Ból kości ogonowej (koccydynia)
Etiologia i przyczyny

Koccydynia, czyli ból kości ogonowej, dotyka głównie kobiety (5-krotnie częściej niż mężczyzn) oraz osoby z nadwagą lub otyłością (ryzyko wzrasta trzykrotnie). Najczęstszą etiologią są urazy zewnętrzne (upadki na kość guziczną, prowadzące do stłuczeń, przemieszczeń lub złamań) oraz przeciążenia wynikające z długotrwałego siedzenia na twardych powierzchniach, szczególnie u osób pracujących przy biurku, kierowców i sportowców (kolarstwo, wioślarstwo). W ostatnim trymestrze ciąży i podczas porodu siodłowego dochodzi do rozmiękczenia tkanek i możliwych urazów kości ogonowej. Patogeneza obejmuje także zmiany zwyrodnieniowe stawów krzyżowo-ogonowych, hipermobilność lub hipomobilność kości ogonowej, ostrogi kostne oraz warianty morfologiczne kości. W rzadkich przypadkach ból może być objawem nowotworów (np. chordoma, rak prostaty, rak jelita grubego), infekcji (osteomyelitis) lub torbieli pilonidalnych.

Ból kości ogonowej (koccydynia) – Etiologia, przyczyny, powstawanie

Ból kości ogonowej, medycznie określany jako koccydynia (lub koccygodynia), to dolegliwość zlokalizowana w dolnej części kręgosłupa, gdzie znajduje się kość ogonowa (kość guziczna, kość ogonowa). Dolegliwość ta dotyka znacznie częściej kobiety niż mężczyzn (około 5 razy częściej), a ryzyko jej wystąpienia zwiększa się również u osób z nadwagą lub otyłością.123

Urazy i traumy

Najczęstszą przyczyną koccydynii są urazy zewnętrzne lub wewnętrzne. Urazy zewnętrzne zazwyczaj powstają w wyniku upadku do tyłu bezpośrednio na kość ogonową, co może prowadzić do stłuczenia, przemieszczenia lub złamania kości.12 Taki urazowy mechanizm uszkodzenia kości ogonowej może wystąpić podczas upadku na lód, upadku ze schodów czy podczas uprawiania sportów, takich jak jazda na rowerze, jazda na łyżwach czy hokej.34

Upadek może również spowodować zapalenie więzadeł i uszkodzenie przyczepu kości ogonowej do kości krzyżowej. Urazy kości ogonowej zwykle prowadzą do stłuczenia, ale mogą również skutkować złamaniem lub przemieszczeniem w przedniej lub tylnej części kości ogonowej.56

Pozycja siedząca i mikrourazy

Długotrwałe siedzenie, szczególnie na twardych lub wąskich powierzchniach, może powodować nadmierny nacisk na kość ogonową, prowadząc do mikrourazów i stanu zapalnego. Dotyczy to zwłaszcza osób, które:

  • Siedzą długo w pracy przy biurku
  • Prowadzą pojazdy przez długie okresy
  • Jeżdżą na rowerze
  • Uprawiają wioślarstwo

123

Te czynności wymagają wielokrotnego pochylania się do przodu i do tyłu, co może powodować nadmierne naprężenia tkanek otaczających kość ogonową i prowadzić do przewlekłego bólu.45

Ciąża i poród

W ostatnim trymestrze ciąży organizm kobiety wydziela hormony, które powodują rozmiękczenie tkanek między kością ogonową a kością krzyżową. Jest to naturalny proces, który zwiększa elastyczność kości ogonowej podczas porodu, tworząc więcej przestrzeni w kanale rodnym. Jednakże, czasami ten proces może prowadzić do nadmiernego rozciągnięcia mięśni i więzadeł wokół kości ogonowej, powodując ból.12

Podczas porodu siodłowego znaczny nacisk wywierany na kość ogonową przez główkę dziecka przechodzącą przez miednicę może doprowadzić do urazów kości ogonowej i otaczających ją struktur. W rzadkich przypadkach może dojść nawet do złamania kości ogonowej.34

Masa ciała

Zarówno nadwaga jak i niedowaga mogą przyczyniać się do bólu kości ogonowej:

  • Nadwaga/otyłość: Dodatkowy ciężar wywiera większy nacisk na kość ogonową, zwłaszcza podczas siedzenia. Może to powodować odchylenie kości ogonowej do tyłu, co prowadzi do jej nieprawidłowego ustawienia i bólu. Osoby otyłe mają trzykrotnie większe ryzyko wystąpienia bólu kości ogonowej w porównaniu do osób o prawidłowej masie ciała.123
  • Niedowaga: Zbyt mała ilość tkanki tłuszczowej w okolicy pośladków powoduje brak odpowiedniego amortyzowania i ochrony kości ogonowej. W rezultacie kość ogonowa może ocierać się o mięśnie, więzadła i ścięgna, powodując stan zapalny i ból.12

Zmiany degeneracyjne i schorzenia stawów

Nieurażowa koccydynia może wynikać z szeregu przyczyn, w tym z choroby zwyrodnieniowej stawów lub dysków, nadmiernej ruchomości lub ograniczenia ruchomości stawu krzyżowo-ogonowego.1 Zmiany zwyrodnieniowe w kręgosłupie wraz z wiekiem mogą obejmować:

  • Osteoartrozę stawów kości ogonowej powodująca ból z powodu zużycia i tarcia23
  • Degeneracyjne zmiany chrząstki w kręgosłupie, powodujące tarcie kręgów o siebie4
  • Zrost małych dysków chrząstkowych utrzymujących kość ogonową na miejscu5

Nieprawidłowości anatomiczne

Ból kości ogonowej może wynikać z wariantów morfologii kości ogonowej, takich jak:12

  • Nieprawidłowa ruchomość kości ogonowej:
  • Ostrogi kostne: Przerośnięta lub pogrubiona kość (ostroga kostna) w pobliżu końcówki kości ogonowej może zmieniać jej długość i/lub normalny kąt ustawienia, powodując ból podczas siedzenia567
  • Skoliotyczne zniekształcenie (boczne odchylenie) kości ogonowej8
  • Nadmierne zgięcie lub wyprost kości ogonowej8

Rzadkie przyczyny

W bardzo rzadkich przypadkach ból kości ogonowej może być objawem poważniejszych schorzeń, takich jak:12

  • Nowotwory: Zarówno pierwotne, jak i przerzutowe zmiany nowotworowe mogą powodować ból kości ogonowej. Do nowotworów najczęściej związanych z bólem kości ogonowej należą:
  • Infekcje: Zapalenie kości i szpiku kostnego (osteomyelitis) w obszarze kości ogonowej, szczególnie u osób z obniżoną odpornością67
  • Torbiele: Torbiel włosowa (cysty pilonidalne) – nieprawidłowa kieszeń w skórze, zwykle w pobliżu kości ogonowej, zawierająca włosy i resztki skóry, która po zakażeniu może powodować obrzęk i ból89

Inne przyczyny

Inne możliwe przyczyny bólu kości ogonowej obejmują:

  • Uszkodzenie mięśni dna miednicy może prowadzić do lokalnego dyskomfortu12
  • Wiek – zmiany zwyrodnieniowe w połączeniu krzyżowo-ogonowym oraz w stawach międzykręgowych kości ogonowej, a także zrosty w tych miejscach, wydają się nasilać wraz z wiekiem3
  • Hemoroidy – tkanka, która amortyzuje i chroni otwór analny, ulega zapaleniu, a mięśnie ciągną kość ogonową, co może powodować ból4
  • Ból przeniesiony z innych obszarów kręgosłupa lub miednicy, np. z przepukliny dysku lędźwiowego lub choroby zwyrodnieniowej dysku lędźwiowego56
  • Nadmierna aktywność mięśni dna miednicy7
  • Zaburzenia psychiczne, takie jak zaburzenia somatyzacyjne8

W wielu przypadkach (do 30%) przyczyna bólu kości ogonowej pozostaje nieznana – określana jest wówczas jako idiopatyczna koccydynia.123

Czynniki ryzyka bólu kości ogonowej

Określone czynniki zwiększają ryzyko rozwoju koccydynii:123

  • Płeć żeńska: Kobiety są 5 razy bardziej narażone na koccydynię niż mężczyźni, co wynika z szerszego kąta miednicy i większego narażenia kości ogonowej na urazy podczas porodu
  • Otyłość: Osoby otyłe mają trzykrotnie wyższe ryzyko rozwoju koccydynii
  • Aktywność zawodowa: Osoby wykonujące prace wymagające długotrwałego siedzenia
  • Aktywność sportowa: Osoby uprawiające sporty takie jak kolarstwo czy wioślarstwo
  • Wiek: Zmiany degeneracyjne występujące wraz z wiekiem zwiększają ryzyko koccydynii

Mechanizmy powstawania bólu kości ogonowej

Ból kości ogonowej może powstawać w wyniku różnych mechanizmów patofizjologicznych:12

  • Bezpośredni uraz pionowy na kość ogonową może prowadzić do różnych skutków – od stłuczenia do złamania-przemieszczenia
  • Urazowe lub nieurazowe uszkodzenie więzadeł kości ogonowej może skutkować niestabilnością dynamiczną kości ogonowej (nadmierny ruch kości ogonowej podczas obciążenia lub siedzenia)
  • Zapalenie okostnej kości ogonowej (faktycznie odnosimy się do zapalenia okostnej kości ogonowej, gdy mówimy o zapaleniu kości ogonowej)3
  • Niestabilność stawów kości ogonowej powodująca przewlekły stan zapalny4
  • Ucisk przez ostrogę kostną na końcu kości ogonowej podczas siedzenia5
  • Skurcz mięśni przyczepionych do kości ogonowej6

Koccygodynia o wielu przyczynach

Warto podkreślić, że u pacjentów może występować więcej niż jedna przyczyna bólu kości ogonowej. Przykłady takich złożonych sytuacji to:1

  • Jednoczesne występowanie hipermobilności kości ogonowej i ostrogi kostnej na końcu kości ogonowej
  • Ból powodowany przez nieprawidłowości w dwóch różnych stawach w obrębie kości ogonowej
  • Zapalenie stawów w górnej części kości ogonowej i inne problemy w dolnej części

Ta złożoność przyczyn podkreśla potrzebę dokładnej diagnostyki i indywidualnego podejścia do leczenia bólu kości ogonowej.1

Zrozumienie przyczyn bólu kości ogonowej jest kluczowe dla właściwego leczenia. Chociaż w większości przypadków koccydynia ustępuje samoistnie po kilku tygodniach lub miesiącach z pomocą środków domowych, w niektórych przypadkach może trwać dłużej, szczególnie przy poważniejszych urazach.12

    https://pmc.ncbi.nlm.nih.gov/articles/PMC3963058/
    Despite its small size, the coccyx has several important functions. […] The incidence of coccydynia (pain in the region of the coccyx) has not been reported, but factors associated with increased risk of developing coccydynia include obesity and female gender. […] The most common etiology of coccydynia is external or internal trauma. External trauma usually occurs due to a backwards fall, leading to a bruised, dislocated, or broken coccyx. […] Nontraumatic coccydynia can result from a number of causes, including degenerative joint or disc disease, hypermobility or hypomobility of the sacrococcygeal joint, infectious etiology, and variants of coccygeal morphology. […] Coccydynia can also be associated with nonorganic causes, such as somatization disorder and other psychological disorders.

    https://my.clevelandclinic.org/health/diseases/10436-coccydynia-tailbone-pain
    Tailbone pain can occur if you bruise your tailbone (located just below your sacrum) during a fall or other trauma. You can get tailbone pain after a fall or another type of trauma. Soreness often increases when you sit down. […] Coccydynia is the medical term for tailbone pain (coccyx = tailbone, dynia = pain). […] There are many reasons why you might develop tailbone pain. Possible tailbone pain causes include: Falls. A bad fall can bruise, break (fracture) or dislocate your tailbone. Repetitive strain injuries (RSI). Sports like bicycling and rowing require you to lean back and forth. Too much of that repeated motion can strain the tissues around your tailbone. Pregnancy or childbirth. During the third trimester of pregnancy, your body secretes hormones that soften the area between your tailbone and sacrum (the part of your pelvis just above your tailbone). This gives your tailbone more flexibility during childbirth. Its a natural process. But in some cases, this can stretch the muscles and ligaments around your tailbone too far, causing additional pain. The strain on these soft tissues keeps them from supporting your tailbone at the correct angle. Carrying extra weight. Extra weight places additional pressure on your tailbone. This can make your tailbone lean backwards, resulting in pain. Not carrying enough weight. Less fat means less cushioning in your butt. Without this cushion, your tailbone may rub against your muscles, ligaments and tendons, causing inflammation. Prolonged sitting. Sitting for long periods of time can place excess pressure on your tailbone, especially if you sit on hard surfaces.

    In very rare cases, tailbone pain may be a sign of cancer near your coccyx or metastatic cancer thats spread to your bones. This is very uncommon. Cancers most likely to cause tailbone pain include: Chordoma. Prostate cancer. Colorectal (colon) cancer. […] Tailbone pain treatment depends on the cause and the severity of your discomfort. Home remedies might be all you need. But if home remedies dont work, your provider may recommend nonsurgical or surgical treatments. […] You cant always prevent tailbone pain because it often occurs after accidents or as a symptom of an underlying condition. You might be able to reduce your risk if you: Avoid sitting for long periods of time, especially on hard surfaces. Use caution when cycling or participating in other activities that could cause tailbone pain. […] Tailbone pain usually goes away on its own in a few days with the help of home remedies and a little bit of patience. It can take a little longer for more severe injuries.
  • #1 Tailbone pain: Causes, diagnosis, and relief
    https://www.medicalnewstoday.com/articles/318064
    Tailbone pain or pain in the coccyx may occur suddenly after an obvious injury. It can also appear over time, with no apparent cause. Doctors may call it coccydynia. […] A wide range of health issues can cause tailbone pain. […] Sources of tailbone pain include, but are not limited to, the following: Physical damage to the coccyx or the tissue surrounding it is the most common cause of tailbone pain. Falls, knocks, and trauma experienced in childbirth can all cause coccyx injuries. […] As the cartilage in the spine wears down, vertebrae may rub against each other, causing pain. Changes in the spine can also place excess pressure on the coccyx. […] Damage to a person’s pelvic floor muscles can lead to localized discomfort. […] An infection of the spine or the tissue surrounding it can lead to pain in the tailbone region.
  • #1 Tail Bone Pain (Coccygodynia) Symptoms and Treatment
    https://www.verywellhealth.com/tail-bone-pain-296530
    Tailbone pain, technically called coccygodynia, can result from a fall or other trauma onto the very bottom part of your spine. Such trauma can bruise the periosteum (connective tissue that surrounds the bone), causing pain. Falls onto the tail bone can also fracture the bone, dislocate it (at the sacrococcygeal joint, which is the place where the coccyx and the sacrum come together,) or both. […] Problems with your coccyx bone that can result in coccygodynia may include injuries (including but not limited to falls, as discussed above), disc degeneration at your sacrococcygeal (defined above) and/or intercoccygeal joints (joints between the tiny bone pieces that together comprise the coccyx), bone spurs at the coccyx (called coccygeal spicule), infection in the bone (called osteomyelitis) or a tumor on the bone. […] Childbirth is another possible cause of coccygodynia (in the mother). […] Finally, your coccygodynia maybe be a case of „cause unknown.” A 2012 review of studies states that 30% of coccygodynia is idiopathic; in other words, the reason for the tail bone pain could not be found.
  • #1 Coccyx Pain – StatPearls – NCBI Bookshelf
    https://www.ncbi.nlm.nih.gov/books/NBK563139/
    Coccyx pain is known by multiple synonyms, including coccydynia, coccygodynia, and tailbone pain. There are many causes of coccygeal pain, ranging from musculoskeletal injuries to infections and fatal malignancies. […] Direct vertical trauma, repetitive microtrauma, and childbirth are common causes of coccyx pain. However, more serious underlying causes must be excluded, such as infections (including both soft tissue abscess and osteomyelitis) or malignancy (including chordoma, which has a high fatality rate). […] The outcome of direct vertical trauma to the coccyx can vary from contusion to fracture-dislocation of the coccyx. Traumatic or non-traumatic compromise of the coccygeal ligaments can result in coccygeal dynamic instability (excessive movement of the coccyx during weight-bearing or while sitting).

    Yes, it is certainly possible for patients to have more than one location of coccyx problem. […] For example, I frequently see patients who have both the most common cause of coccyx pain (hypermobility, diagnosed by sitting-versus-standing x-rays) and they may ALSO have the 2nd most common cause of coccyx pain, which is a bone spur at the distal/lowest tip of the coccyx. […] Or, some patients may have pain being caused by hypermobility or other abnormalities at TWO different joints within the coccyx, not just one joint. […] Or, a patient may have arthritis at the upper coccyx, and tables for at the lower coccyx. […] Other combinations are also possible.

    Prolonged or unsupported sitting: Sitting may contribute to tailbone pain, especially if you sit on a narrow or hard surface for extended durations. […] Repetitive Strain Injury (RSI): Activities that involve repetitive leaning and stretching of the spine like rowing and cycling can strain the soft tissues around the tailbone. […] Coccydynia most frequently affects adults and adolescents, obese individuals and women. Females are five times more likely to experience coccyx pain than males, especially with childbirth-related injuries being a significant factor.

    https://www.nhs.uk/conditions/tailbone-coccyx-pain/
    Tailbone (coccyx) pain may improve after a few weeks, but it can sometimes last longer. […] Common causes of tailbone (coccyx) pain include: pregnancy and childbirth, an injury or accident, such as a fall onto your coccyx, repeated or prolonged strain on the coccyx for example, after sitting for a long time while driving or cycling, poor posture, being overweight or underweight, joint hypermobility (increased flexibility) of the joint that attaches the coccyx to the bottom of the spine.

    During pregnancy, your body secretes hormones that soften the area between your tailbone and sacrum, and sometimes, this can stretch the muscles and ligaments around the tailbone so much that it causes pain. […] Childbirth is a well-known cause of coccydynia. Ligaments and muscles around the coccyx can get stretched and strained during delivery and cause pain. […] If you have hemorrhoids, the tissue that cushions and protects your anal opening gets inflamed and muscles pull on your coccyx. That can cause tailbone pain. […] Carrying too much weight puts extra pressure on your coccyx when you sit down, which can lead to tailbone pain. […] Tailbone pain may stem from chordoma, a rare, cancerous tumor that develops in your spine, the base of your skull, or your tailbone. […] Tailbone pain is sometimes related to prostate cancer, a common cancer in men. […] A tumor or cancer in your colon or rectum can cause tailbone pain. […] A pilonidal cyst is an abnormal pocket in the skin, typically near the tailbone at the top of the buttocks. It usually contains hair and skin debris. When a cyst gets infected, it causes swelling and pain.

    A womans body secretes hormones during the third trimester of pregnancy that softens the region between the sacrum and the coccyx. This enables the widening of the pelvic area to make childbirth easier. This also results in the coccyx moving as needed when giving birth. Although this is a normal bodily process, the movement may unnecessarily stretch the ligaments and muscles surrounding the coccyx, leading to more discomfort. […] The coccyx will undergo more pressure when you gain more weight. As a result, the coccyx may slant backward. This misalignment may lead to pain. […] A sufficient amount of fat is required in the buttocks to keep the coccyx from rubbing against the muscles, ligaments, and tendons. If you are underweight, soft tissues become inflamed from the friction. […] Coccyx pain can exacerbate if you sit for a more extended period daily. It happens mainly if youre seated on a hard or constrained surface.
  • #2 Understanding the Causes of Tailbone Pain

    Coccyx disorders almost always manifest as pain in the coccyx (coccydynia, coccygodynia). There are numerous causes of coccygeal area pain. Many of these causes involve disorders of anatomic structures near the coccyx rather than the coccyx itself. Coccydynia (coccygodynia) refers to pain in and around the coccyx. […] The most common causes of coccyx disorders are musculoskeletal. These can be categorized as involving acute trauma and repetitive microtrauma. […] Acute trauma can involve external (from outside the pelvis) or internal (from inside the pelvis) physical force. […] External physical trauma includes falling and landing directly on to the coccyx, which can cause fracture, dislocation, ligamentous disruption, and joint instability. […] Internal physical trauma to the coccyx classically includes childbirth, in which passage of the neonate through the birth canal can injure the coccyx.

    Falling backward onto a hard floor is a common way people hurt their tailbone. Because of its position at the very bottom of the spine, the tailbone can be very susceptible to injury, says Dr. Barsoum. And if the injury causes the tailbone to move out of position, it can cause pain not only in the moment, but also long term. […] Carrying extra weight puts pressure on the tailbone, throwing off body alignment. Carrying too little weight means theres less fat (aka cushioning) to absorb friction as the coccyx rubs against the surrounding tissues. […] As we age, we lose subcutaneous fat in the area, which can contribute to pain. Additionally, as we get older, the cartilage that helps hold the coccyx in place degrades, so the small bony segments fuse together more tightly. […] Sports like cycling and rowing, which cause you to lean forward for a long time, can cause the muscles at the base of the spine to misalign, as well as put extra pressure on the tailbone.

    Accidental Falls Direct force on the tailbone may cause misalignment, sprain, or in rare cases, fracturing of the coccyx. A fall can also sprain the surrounding ligaments and strain the muscles. This can cause severe pain, which can last for many years if not properly treated. […] Childbirth As the baby passes through the birth canal, it comes in contact with the tailbone. It is possible to injure the tailbone in cases where the coccyx is tilted forward into the birth canal (from a past injury) or if the baby is larger in size. The position of the coccyx can decrease the diameter of the birth canal, which may cause difficult deliveries and lead to re-injury with subsequent pregnancies. For females, it is important to fix past coccyx injuries in order to reduce the chances of re-injury if they give birth again.
