Spondyloza szyjna
Etiologia i przyczyny
Spondyloza szyjna jest powszechną chorobą zwyrodnieniową kręgosłupa szyjnego, której patofizjologia obejmuje degenerację dysków międzykręgowych, utratę ich wysokości i elastyczności, powstawanie pęknięć w pierścieniu włóknistym oraz tworzenie przepuklin dyskowych mogących uciskać korzenie nerwowe i rdzeń kręgowy. Proces ten rozpoczyna się zwykle po 30. roku życia, a objawy kliniczne pojawiają się między 40. a 60. rokiem życia. W odpowiedzi na zwiększone obciążenia mechaniczne dochodzi do powstawania osteofitów na krawędziach trzonów kręgowych, które stabilizują kręgosłup, ale mogą również powodować ucisk struktur nerwowych i zwężenie kanału kręgowego. Dodatkowo, pogrubienie i usztywnienie więzadeł oraz zwyrodnienie stawów międzykręgowych prowadzą do ograniczenia ruchomości i dalszego zwężenia przestrzeni dla struktur nerwowych.
Etiologia spondylozy szyjnej
Spondyloza szyjna (cervical spondylosis) jest powszechną chorobą zwyrodnieniową kręgosłupa szyjnego, dotykającą struktury kostne, dyski międzykręgowe oraz więzadła. Rozwija się przede wszystkim w wyniku naturalnych procesów starzenia się organizmu, prowadząc do zmian w strukturze i funkcji kręgosłupa szyjnego.12 Szacuje się, że około 85-95% osób powyżej 60. roku życia wykazuje zmiany zwyrodnieniowe kręgosłupa szyjnego widoczne w badaniach obrazowych, choć nie u wszystkich występują objawy kliniczne.34
Zmiany związane z wiekiem jako główna przyczyna
Głównym czynnikiem etiologicznym spondylozy szyjnej jest naturalny proces starzenia się, który prowadzi do degeneracji elementów kręgosłupa. Proces ten najczęściej rozpoczyna się po 30. roku życia, a pierwsze objawy kliniczne zazwyczaj pojawiają się między 40. a 60. rokiem życia.56 Wiek jest najistotniejszym czynnikiem ryzyka rozwoju spondylozy szyjnej, a zmiany zwyrodnieniowe kręgosłupa szyjnego są powszechne u osób w podeszłym wieku.78
Patofizjologia spondylozy szyjnej
Patofizjologia spondylozy szyjnej obejmuje kilka kluczowych procesów, które wzajemnie na siebie oddziałują, prowadząc do charakterystycznych zmian zwyrodnieniowych:910
Degeneracja i odwodnienie dysków międzykręgowych
Pierwsze zmiany w patogenezie spondylozy szyjnej dotyczą dysków międzykręgowych. Z wiekiem dyski międzykręgowe ulegają stopniowej degeneracji, która obejmuje:1112
- Utratę zawartości wody, prowadzącą do odwodnienia i zmniejszenia wysokości dysku
- Zmniejszenie elastyczności i zdolności amortyzacyjnych
- Stopniowy rozpad proteoglikanów w macierzy dysku
- Powstawanie pęknięć i szczelin w pierścieniu włóknistym
Procesy te rozpoczynają się zazwyczaj około 40. roku życia. Odwodnienie dysków międzykręgowych prowadzi do zmniejszenia ich wysokości i elastyczności, co z kolei powoduje zwiększenie obciążenia innych struktur kręgosłupa, w tym stawów międzykręgowych i więzadeł.34
Tworzenie wypuklin i przepuklin dyskowych
W miarę postępu degeneracji, osłabiony pierścień włóknisty może ulegać wypuklinom i przepuklinom:56
- Jądro miażdżyste może przemieszczać się przez szczeliny w pierścieniu włóknistym
- Przepukliny dyskowe mogą uciskać korzenie nerwowe lub rdzeń kręgowy
- Przepuklina dysku może prowadzić do zapalenia i podrażnienia otaczających struktur nerwowych
Tworzenie osteofitów (narośli kostnych)
W odpowiedzi na zwiększone obciążenia mechaniczne i degenerację dysków, organizm próbuje stabilizować kręgosłup poprzez tworzenie wyrośli kostnych, zwanych osteofitami:34
- Osteofity (narośle kostne) tworzą się na krawędziach trzonów kręgowych
- Ich powstawanie jest mechanizmem kompensacyjnym organizmu, mającym na celu zwiększenie powierzchni nośnej i stabilizację kręgosłupa
- Mogą one jednak uciskać struktury nerwowe, w tym korzenie nerwowe i rdzeń kręgowy
- Mogą również zmniejszać średnicę otworów międzykręgowych i kanału kręgowego
Zmiany w więzadłach i stawach międzykręgowych
Wraz z postępem choroby dochodzi do zmian w więzadłach i stawach kręgosłupa:45
- Więzadła kręgosłupa, w tym więzadło żółte i więzadła podłużne, ulegają pogrubieniu i usztywnieniu
- Zmniejsza się elastyczność i zakres ruchu kręgosłupa szyjnego
- Stawy międzykręgowe (fasetowe) ulegają przerostowi i zwyrodnieniu
- Przerost więzadła żółtego może dodatkowo zmniejszać średnicę kanału kręgowego
Czynniki ryzyka spondylozy szyjnej
Poza naturalnym procesem starzenia się, istnieje szereg dodatkowych czynników, które mogą przyspieszać rozwój spondylozy szyjnej lub zwiększać ryzyko jej wystąpienia:12
Czynniki genetyczne
Predyspozycje genetyczne mogą odgrywać istotną rolę w rozwoju spondylozy szyjnej:12
- Rodzinne występowanie spondylozy szyjnej sugeruje genetyczne podłoże choroby
- Niektóre osoby mogą mieć wrodzoną węższy kanał kręgowy, co predysponuje do wcześniejszego rozwoju objawów uciskowych
- Genetycznie uwarunkowana budowa dysków międzykręgowych może wpływać na szybkość ich degeneracji
- Cechy dziedziczne, takie jak nieprawidłowa budowa stawów lub skłonność do szybszego zużycia tkanki chrzęstnej
Urazy i przeciążenia kręgosłupa
Przebyte urazy kręgosłupa szyjnego oraz przewlekłe przeciążenia znacząco zwiększają ryzyko rozwoju spondylozy:12
- Urazy typu „whiplash” (uraz kręgosłupa szyjnego spowodowany nagłym szarpnięciem głowy, np. podczas wypadku samochodowego)
- Złamania i zwichnięcia kręgów szyjnych
- Mikrourazy związane z powtarzalnymi ruchami głowy i szyi
- Przeciążenia związane z długotrwałym utrzymywaniem niewłaściwej pozycji głowy i szyi
Czynniki zawodowe i ergonomiczne
Wykonywany zawód i związane z nim obciążenia kręgosłupa szyjnego mogą istotnie wpływać na rozwój spondylozy:12
- Zawody wymagające długotrwałego utrzymywania głowy w jednej pozycji (np. praca biurowa przy komputerze)
- Prace związane z ciągłymi ruchami szyi (np. niektóre zawody techniczne)
- Zawody wymagające dźwigania ciężarów na ramionach lub głowie
- Prace związane z ekspozycją na wibracje (np. kierowcy zawodowi)
- Czynności wykonywane przez dłuższy czas z głową pochyloną lub zadartą do góry
Styl życia i choroby współistniejące
Różne aspekty stylu życia oraz choroby towarzyszące mogą przyspieszać rozwój spondylozy szyjnej:12
- Palenie tytoniu (udowodniono związek z przyspieszonym rozwojem zmian zwyrodnieniowych)
- Nadwaga i otyłość (zwiększone obciążenie kręgosłupa)
- Siedzący tryb życia i brak aktywności fizycznej
- Zaburzenia postawy ciała
- Choroby systemowe wpływające na tkankę kostną i chrzęstną, np. osteoporoza, reumatoidalne zapalenie stawów
- Zaburzenia psychiczne, takie jak depresja i stany lękowe (mogą nasilać percepcję bólu i wpływać na napięcie mięśniowe)
Wcześniejsze zabiegi chirurgiczne kręgosłupa
Przebyte operacje kręgosłupa szyjnego mogą przyczyniać się do szybszego rozwoju spondylozy:1
- Zabiegi stabilizacyjne mogą zwiększać obciążenie sąsiednich segmentów ruchowych
- Zmiany biomechaniki kręgosłupa po operacjach mogą prowadzić do przeciążeń i przyspieszonej degeneracji
- Blizny pooperacyjne mogą wpływać na ruchomość i elastyczność tkanek
Szczególne warianty etiologiczne spondylozy szyjnej
Istnieją pewne szczególne warianty i sytuacje kliniczne, które mogą zwiększać ryzyko rozwoju spondylozy szyjnej lub modyfikować jej przebieg:12
Choroby neurologiczne wpływające na napięcie mięśniowe
Niektóre schorzenia neurologiczne mogą przyczyniać się do rozwoju spondylozy szyjnej:12
- Dystonia szyjna (kręcz szyi)
- Mózgowe porażenie dziecięce z zajęciem mięśni szyi
- Choroby neurodegeneracyjne z nieprawidłowym napięciem mięśniowym
Aktywność sportowa wysokiego ryzyka
Niektóre dyscypliny sportowe wiążą się ze zwiększonym ryzykiem urazów i przeciążeń kręgosłupa szyjnego:1
- Rugby i sporty kontaktowe
- Zapasy i sporty walki
- Jeździectwo
- Gimnastyka z elementami akrobatycznymi
- Nurkowanie
Wrodzone anomalie kręgosłupa
Wady wrodzone kręgosłupa mogą predysponować do wcześniejszego rozwoju spondylozy:12
- Wrodzone zwężenie kanału kręgowego
- Wrodzone bloki kostne (zrosty kręgów)
- Anomalie rozwojowe kręgów i stawów
- Wady rozwojowe krążków międzykręgowych
Złożoność etiologii spondylozy szyjnej
Spondyloza szyjna jest chorobą o złożonej etiologii, w której główną rolę odgrywa naturalny proces starzenia się organizmu. Niemniej jednak, szereg czynników genetycznych, środowiskowych, zawodowych i związanych ze stylem życia może istotnie wpływać na tempo rozwoju zmian zwyrodnieniowych i nasilenie objawów klinicznych.123
Zrozumienie wieloczynnikowej etiologii spondylozy szyjnej pozwala na identyfikację osób z grup zwiększonego ryzyka oraz wdrożenie odpowiednich działań profilaktycznych. Mimo że proces zwyrodnieniowy jest nieodwracalny i stanowi naturalną konsekwencję starzenia się, modyfikacja określonych czynników ryzyka, takich jak poprawa ergonomii pracy, redukcja masy ciała czy zaprzestanie palenia tytoniu, może potencjalnie spowolnić postęp choroby i zmniejszyć nasilenie objawów.12

Cervical spondylosis is a natural age-related disease process that is associated with degenerative changes within the intervertebral disc. […] The primary risk factor and contributor to the incidence of cervical spondylosis is age-related degeneration of the intervertebral disc and cervical spinal elements. […] Factors that can contribute to an accelerated disease process and early-onset cervical spondylosis include exposure to significant spinal trauma, a congenitally narrow vertebral canal, dystonic cerebral palsy affecting cervical musculature, and specific athletic activities like rugby, soccer, and horse riding.

Cervical spondylosis is a general term for age-related wear and tear affecting the spinal disks in your neck. […] As people age, the structures that make up the backbone and neck gradually develop wear and tear. These changes can include: […] Dehydrated disks. Disks act like cushions between the vertebrae of the spine. By the age of 40, most people’s spinal disks begin drying out and shrinking. As the disks become smaller, there is more bone-on-bone contact between the vertebrae. […] Herniated disks. Cracks also appear on the exterior of the spinal disks. The soft interior of a disk can squeeze through these cracks. Sometimes, it presses on the spinal cord and nerve roots. […] Bone spurs. As the disks break down, the body may produce extra amounts of bone in a misguided effort to strengthen the spine. These bone spurs can sometimes pinch the spinal cord and nerve roots. […] Stiff ligaments. Ligaments are cords of tissue that connect bone to bone. Spinal ligaments can stiffen with age, making the neck less flexible.

Cervical spondylosis arises from degenerative changes that occur in the spine as we age. These changes are normal and they occur in everyone. […] Cervical spondylosis, commonly called arthritis of the neck, is the medical term for these age-related, wear-and-tear changes that occur over time. […] Age is the most common risk factor for cervical spondylosis. The condition is extremely common in patients who are middle-aged and older. […] Other factors that may increase your risk for developing cervical spondylosis and neck pain include: Genetics a family history of neck pain and spondylosis, Smoking clearly linked to increased neck pain, Occupation jobs with lots of repetitive neck motion and overhead work, Depression or anxiety, Previous injury or trauma to the neck. […] As the disks in the spine age, they lose height and begin to bulge. They also lose water content, begin to dry out and weaken. […] Over time, these bone overgrowths called bone spurs may narrow the space for the nerves and spinal cord to pass through (stenosis). Bone spurs may also lead to decreased range of motion in the spine.
- #1 Cervical Spondylosis – UF Healthhttps://ufhealth.org/conditions-and-treatments/cervical-spondylosis
Cervical spondylosis is caused by aging and chronic wear on the cervical spine. This includes the disks or cushions between the neck vertebrae and the joints between the bones of the cervical spine. There may be abnormal growths or spurs on the bones of the spine (vertebrae). […] The major risk factor is aging. By age 60, most people show signs of cervical spondylosis on x-ray. Other factors that can make someone more likely to develop spondylosis are: Being overweight and not exercising, Having a job that requires heavy lifting or a lot of bending and twisting, Past neck injury (often several years before), Past spine surgery, Ruptured or slipped disk, Severe arthritis, Previous surgery on the neck.

Cervical spondylosis is a common age-related neck condition caused by wear-and-tear arthritis of the spinal joints in your neck. […] Arthritis in the neck starts with osteophytes (aka bone spurs) that form on vertebral bodies as they break down. Bone spurs are the body’s response to joint wear and tear. […] A major risk factor for cervical spondylosis is age. Once you reach 40, your likelihood of developing neck arthritis increases. By age 60, according to The American Academy of Orthopedic Surgeons, more than 85% of people have cervical spondylosis. […] If you have relatives with cervical spondylosis, you have a higher risk of developing it yourself. Some researchers think this may be due to inherited factors such as a naturally narrow spinal canal or smaller-than-average passages between vertebrae.

Spondylosis is caused by repetitive stress from overloading the spine, wear and tear due to ageing, as well as injury. […] Other causes include: […] Dehydrated discs due to ageing. The discs in the spine act like cushions between the vertebrae. By around the age of 40, the spinal discs start to dry out and shrink, which leads to more bone-on-bone contact between the vertebrae. […] Herniated discs due to ageing. With age, the exterior of the spinal discs wear down and cracks can happen, leading to bulging (herniated) discs that press on the spinal cord and nerve roots. […] Bone spurs due to disc degeneration. When the discs wear down, the body produces extra bone to stabilise the segment. These bone spurs often lead to pinching of the nerve roots or spinal cord. […] Stiff ligaments due to ageing. Ligaments are cords of tissue that connect bone to bone. Ligaments can stiffen over time, making the back less flexible.
- #2 Cervical Spondylosis – Prof. Nicola Portinaro – Orthopedic Suregonhttps://www.nicolaportinaro.com/cervical-spondylosis/
Cervical spondylosis occurs as you age because the cartilage in the cervical spine degenerates and develop wear and tear. […] Possible causes include: […] Dehydrated spinal discs. Inside the spinal discs, there is a gel-like material that can dry over time. This increases the contact between the bones of the vertebrae and causes pain […] Bone spurs. the body can try to grow an extra amount of bones to make the spine stronger. these bone spurs can pinch the nerve root and the spinal cord […] Herniated discs. Spinal discs can develop cracks that lead to herniated discs. The material that leaks out can press the spinal cord and nerves and cause Cervical spondylosis symptoms […] Stiff ligaments. Ligaments are tough cords that connect your spinal bones to each other. They can become stiffer over time, affecting neck movement and making the neck tight and less flexible. […] Injury and Overuse. If youve had a car accident that injured your neck this can accelerate the ageing process. Also overuse due to a particular occupation or repetitive activity that involve the movement of your neck or heavy lifting can result in premature wear and tear.

4. Genetic Predisposition […] Genetics also play a role in the development of cervical spondylosis. Some individuals may have a genetic predisposition to degenerative spine conditions, including spondylosis. Certain inherited traits might also make some people more susceptible to early-onset degeneration in the cervical spine. […] 5. Smoking and Unhealthy Habits […] Unhealthy lifestyle habits, particularly smoking, have been linked to an increased risk of cervical spondylosis. Smoking affects blood circulation and can impair the delivery of nutrients to spinal discs, accelerating degeneration. Other unhealthy habits like a sedentary lifestyle, poor nutrition and excessive alcohol consumption may also contribute to the development of this condition.

- #2 Spondylosis > Fact Sheets > Yale Medicinehttps://www.yalemedicine.org/conditions/spondylosis
Neck or back pain that develops as we age may be a sign of spondylosis, a degenerative condition that affects the spine. Spondylosis is a normal, age-related condition. In fact, an estimated 90% of adults aged 60 years or older have this condition. […] The most common cause of spondylosis is the cumulative joint stress that occurs as people age. It predisposes them to osteoarthritis, a common form of arthritis typically associated with progressive wear and tear on joint cartilage. […] Spondylosis may also arise as a result of previous trauma to the spine. For instance, this condition is more likely to occur among patients who: Have had car accidents, falls, or other spinal injuries, Play competitive sports, Perform strenuous physical activity at work, Have had a previous neck or back surgery.
- #2 Cervical Spondylosis: Symptoms, Causes, Diagnosis, Treatmenthttps://www.verywellhealth.com/arthritis-in-the-neck-cervical-spondylosis-296658
Studies show that smoking is a risk factor for neck pain. Researchers suspect smoking could speed up the process of cervical disc degeneration, especially in the lower discs. […] Depression and anxiety are psychological risk factors for neck pain in general, and research shows depression may increase your risk of developing cervical spondylosis. […] Your occupation can be a significant risk factor for cervical spondylosis if it involves repetitive neck motions, working above your head, heavy lifting, poor ergonomics, or exposure to vibration. […] While most people with neck arthritis haven’t had previous neck injuries, trauma to your neckâand especially repeated traumaâincreases your risk for cervical spondylosis.

Genetics Sometimes the problem runs in families. […] Occupation Jobs that involve several repetitive motion or heavy lifting tend to put more stress on the cervical spine […] Overweight People who are overweight tend to develop osteoarthritis. Excess weight means more stress on the joints, which can lead to inflammation. […] The risk of neck arthritis increases with age. Other risk factors that lead to early degeneration or arthritis include smoking, family history, occupation, neck injury, depression, anxiety, heavy lifting, straining your neck and if one is exposed to a lot of vibration like truck drivers.

Cervical spondylosis can cause pain, headaches, and other symptoms as the cartilage in the neck wears down. […] Several factors can increase the risk of developing cervical spondylosis: […] Age: The most common cause, with symptoms often starting in your 40s or 50s. […] Genetics: If family members have cervical spondylosis, you may be more likely to develop it. […] Injury or surgery: Past trauma or surgeries can speed up the degeneration process. […] Smoking: Tobacco use has been linked to increased neck pain and arthritis. […] Occupation: Jobs that involve repetitive neck movements or heavy lifting can contribute to degeneration.
- #2 Cervical Spondylosis- Causes, Presentation and Treatment | Bone and Spinehttps://boneandspine.com/cervical-spondylosis/
Cervical spondylosis is a term for degenerative changes (wear and tear) of the vertebral discs and facets of the cervical spine. […] Age-related wear and tear is the biggest factor for the development of cervical spondylosis. However repeated occupational trauma like carrying loads, professional dancing, gymnastics etc. which put repeated strains on the neck may contribute. […] Familial cases have also been reported suggesting possible genetic factors also. Smoking is another suggested risk factor. […] Conditions that cause increased mobility or instability to a segment of the cervical spine like the congenitally fused spine, cerebral palsy, Down syndrome etc may be risk factors for cervical spondylosis. […] Marginal osteophytes then begin to develop due to stress. The process could be hastened by trauma or long term heavy use of the neck.
- #2 Cervical Spondylosis: Causes, Symptoms, Home Treatments, and Morehttps://www.healthline.com/health/cervical-spondylosis
Cervical spondylosis is a common, age-related condition that affects the joints and discs in your cervical spine, which is in your neck. Its also known as cervical osteoarthritis or neck arthritis. […] It develops from the wear and tear of cartilage and bones. While its largely the result of age, it can be caused by other factors as well. […] The bones and protective cartilage in your neck are prone to wear and tear that can lead to cervical spondylosis. Possible causes of the condition include: […] Bone spurs […] Dehydrated spinal discs […] Herniated discs […] Injury […] Ligament stiffness […] Overuse. […] The greatest risk factor for cervical spondylosis is aging. Cervical spondylosis often develops as a result of changes in your neck joints as you age. Disc herniation, dehydration, and bone spurs are all results of aging.
- #2https://www.nni.com.sg/patient-care/conditions-treatments/cervical-spondylosis
Cervical spine is made up of bones (vertebraes) with cushions (discs) between them. As we grow older, the bones and the discs will degenerate. Bone spurs (osteophytes) may form and spinal canal may narrow (stenosis). These changes are known as cervical spondylosis. […] As the spine degenerates, osteophytes formation occurs which intends to fuse the vertebrae together to minimise movement. These osteophytes may cause the unwanted symptoms once it comes into contact with any of the nerve root or the spinal cord. The symptoms vary with each individual. […] There is no specific way to prevent this condition. However, some lifestyle modifications may slow the process of the degeneration.
- #3 Cervical Spondylosis: Recognition, Differential Diagnosis, and Managementhttps://pmc.ncbi.nlm.nih.gov/articles/PMC3116771/
Cervical spondylosis is a general and nonspecific term that refers to the degenerative changes that develop either spontaneously with age, or secondarily as the result of trauma or other pathological condition. […] These changes develop slowly. The earliest event is probably a biochemical change in the substance of the disc, resulting in decreased water content. This causes an alteration in the biomechanics of the spine due to loss of the shock absorber-like action of the discs. […] Cervical spondylosis would seem to be unavoidable. The radiographic appearance of human spines reflects this fact. By age 60-65, 95% of nonsymptomatic men and 70% of nonsymptomatic women show at least one degenerative change on plain films. […] Cervical spondylosis is usually associated with mild self-limiting aches and pains or is not symptomatic at all. Nevertheless, individual patients may develop symptoms.

- #3 Spondylosis | Radiology Reference Article | Radiopaedia.orghttps://radiopaedia.org/articles/spondylosis?lang=us
Spondylosis (plural: spondyloses) is used as a broad descriptive term referring to degeneration of the spinal column from any cause; it is usually further qualified by the part of the spine affected, e.g. cervical spondylosis and lumbar spondylosis. […] Spondylosis can be divided into static causes (degeneration) or dynamic causes (due to movements). […] The earliest spondylotic change is disc desiccation. Repetitive movements wear down the vertebral body endplates, compromising vascular supply to the central part of the intervertebral disc (made up of the nucleus pulposus and annulus fibrosus). […] Further disc desiccation results in disc herniation through the posterior annular tear. […] Disc herniation irritates the posterior adjoining ends of the vertebrae, causing the new bone formation, known as an osteophyte.

Facet Joint Arthritis: Facet joints, located at the back of the spine, can undergo degeneration and arthritis. Inflammation and pain can result from facet joint dysfunction. […] Ligament Thickening: Ligaments in the cervical spine may thicken and stiffen, reducing neck mobility and potentially contributing to symptoms. […] Spinal Stenosis: The narrowing of the spinal canal, known as spinal stenosis, can occur with age, compressing the spinal cord and nerve roots. This condition is associated with myelopathy. […] Genetic Factors: Genetics can play a role in the development of cervical spondylosis. Some individuals may have a genetic predisposition to disc degeneration or other structural abnormalities. […] Occupational and Lifestyle Factors: Certain occupations or activities that involve repetitive neck movements or heavy lifting may increase the risk of cervical spondylosis. […] Smoking: Smoking has been linked to accelerated disc degeneration and may contribute to the development of cervical spondylosis. […] Trauma: Previous neck injuries or trauma, even if they occurred years earlier, can accelerate the degenerative process.
- #3 Cervical Spondylosis: Causes, Symptoms & Treatmentshttps://www.physiotattva.com/blog/spondylosis-symptoms-diagnosis-and-treatment
The leading cause of spondylosis is aging. As we age, we wear down the ligaments and bones in our spine, and the intervertebral discs degenerate and weaken. It is prevalent, and over 80% of people over 40 suffer from it. […] Genetics can play a role in the development of spondylosis. If many people in your family have spondylosis, you have a higher risk factor and a stronger genetic predisposition to spondylosis. […] Injuries can be a risk factor for spondylosis. Injuries can cause intervertebral discs to herniate and increase the risk of osteoarthritis. Like sportspersons, people who suffer from repeated trauma to their spine have higher chances of spondylosis. […] Other causes of spondylosis are repeated heavy lifting, misalignment of joints, persistent stress on the spine, and spondylolisthesis.

Cervical spondylosis is a common degenerative disease that gets more acute with age. It is also known as neck arthritis or cervical osteoarthritis. Cervical spondylosis is present in more than 85 percent of people older than age 60. This condition may cause pain and stiffness in the neck for many people, but others with cervical spondylosis may never have any symptoms. […] What causes cervical spondylosis? […] Aging is the greatest risk factor for cervical spondylosis. The condition often develops as an outcome of changes that happen to your neck joints as you grow older. Dehydration, disc herniation, and bone spurs are all results of aging. […] But there are certain factors other than aging that can increase your risk of cervical spondylosis. These include the following: Being inactive and overweight, Injuries to the neck, Holding your neck in an uncomfortable position for long periods of time, Genetic factors, Smoking, Jobs that need repetitive neck movements and awkward positioning, Normal part of aging.

Cervical spondylosis is primarily an age-related condition, and its etiology is multifactorial. Several key factors contribute to the development and progression of this condition: […] Degeneration of Intervertebral Discs: Over time, the intervertebral discs in the cervical spine undergo wear and tear. This degeneration can lead to the loss of disc height and hydration, resulting in reduced shock-absorbing capacity and increased susceptibility to injury. […] Formation of Osteophytes: Osteophytes, also known as bone spurs, often develop as a response to disc degeneration. These bony growths can impinge on surrounding structures, including nerves, leading to pain and other symptoms. […] Herniated Discs: Disc herniation occurs when the inner core of a disc protrudes through its outer layer. This can compress nearby nerves or the spinal cord, causing radiculopathy or myelopathy, respectively.

Spondylosis (plural: spondyloses) is used as a broad descriptive term referring to degeneration of the spinal column from any cause; it is usually further qualified by the part of the spine affected, e.g. cervical spondylosis and lumbar spondylosis. […] Spondylosis can be divided into static causes (degeneration) or dynamic causes (due to movements). […] The earliest spondylotic change is disc desiccation. Repetitive movements wear down the vertebral body endplates, compromising vascular supply to the central part of the intervertebral disc (made up of the nucleus pulposus and annulus fibrosus). […] Further disc desiccation results in disc herniation through the posterior annular tear. […] Disc herniation irritates the posterior adjoining ends of the vertebrae, causing the new bone formation, known as an osteophyte.

Cervical spondylosis is a general term for age-related wear and tear affecting the spinal disks in your neck. […] As people age, the structures that make up the backbone and neck gradually develop wear and tear. These changes can include: […] Dehydrated disks. Disks act like cushions between the vertebrae of the spine. By the age of 40, most people’s spinal disks begin drying out and shrinking. As the disks become smaller, there is more bone-on-bone contact between the vertebrae. […] Herniated disks. Cracks also appear on the exterior of the spinal disks. The soft interior of a disk can squeeze through these cracks. Sometimes, it presses on the spinal cord and nerve roots. […] Bone spurs. As the disks break down, the body may produce extra amounts of bone in a misguided effort to strengthen the spine. These bone spurs can sometimes pinch the spinal cord and nerve roots. […] Stiff ligaments. Ligaments are cords of tissue that connect bone to bone. Spinal ligaments can stiffen with age, making the neck less flexible.

- #9 Cervical Spondylosis: Practice Essentials, Pathophysiology, Epidemiologyhttps://emedicine.medscape.com/article/1144952-clinical
Cervical spondylosis is a chronic degenerative condition of the cervical spine that affects the vertebral bodies and intervertebral disks of the neck (in the form of, for example, disk herniation and spur formation), as well as the contents of the spinal canal (nerve roots and/or spinal cord). Some authors also include the degenerative changes in the facet joints, longitudinal ligaments, and ligamentum flavum. […] Spondylosis progresses with age and often develops at multiple interspaces. Chronic cervical degeneration is the most common cause of progressive spinal cord and nerve root compression. Spondylotic changes can result in stenosis of the spinal canal, lateral recess, and foramina. […] Intervertebral disks lose hydration and elasticity with age, and these losses lead to cracks and fissures. The surrounding ligaments also lose their elastic properties and develop traction spurs. The disk subsequently collapses as a result of biomechanical incompetence, causing the annulus to bulge outward.

Cervical spondylosis is a condition caused by herniated cervical discs, which may press on the spinal nerve roots and cord. […] Nerve compression caused by degenerative cervical spondylosis is a condition caused by herniated cervical discs, which may press on the spinal nerve roots and cord. […] The cervical vertebrae and discs will degenerate due to incorrect or repetitive motions over time. This degeneration will have the following consequences: […] Disk degeneration – Cervical discs begin to degrade around age 35, causing the spinal joints to work harder and narrowing the spinal nerve foramen. […] Herniated disks – With increased age, degenerated discs are prone to herniate and may impinge on the spinal cord and nerve roots. […] Bone spurs – Intervertebral disc degeneration can result in the formation of bone in the vertebrae to support the joints, but this can likewise impose pressure on the spinal cord and nerve roots. […] Age – Cervical spondylosis is more common as we age. […] Neck injury – Prior neck injuries increase the risk of developing cervical spondylosis. […] Smoking – Smoking makes cervical spondylosis more likely.
