• #1 Dislocated shoulder – Symptoms and causes – Mayo Clinic

  https://www.mayoclinic.org/diseases-conditions/dislocated-shoulder/symptoms-causes/syc-20371715

  The shoulder joint is the most frequently dislocated joint of the body. Because it moves in several directions, the shoulder can dislocate forward, backward or downward. It might dislocate completely or partially. […] Most dislocations occur through the front of the shoulder. The ligaments tissue that joins the bones of the shoulder can be stretched or torn, often making the dislocation worse. […] It takes a strong force, such as a sudden blow to the shoulder, to pull the bones out of place. Extreme twisting of the shoulder joint can pop the ball of the upper arm bone out of the shoulder socket. In a partial dislocation, the upper arm bone is partially in and partially out of the shoulder socket. […] Causes of a dislocated shoulder include: Sports injuries. Shoulder dislocation is a common injury in contact sports, such as football and hockey. It’s also common in sports that might involve falls, such as downhill skiing, gymnastics and volleyball. […] Trauma not related to sports. A hard blow to the shoulder during a motor vehicle accident can cause dislocation. […] Falls. Landing awkwardly after a fall, such as from a ladder or from tripping on a loose rug, can dislocate a shoulder.

  https://www.cedars-sinai.org/health-library/diseases-and-conditions/s/shoulder-dislocation.html

  If you have dislocated your shoulder, your upper arm bone (humerus) has moved out of your shoulder joint. This is the most frequently dislocated major joint of your body. Dislocation is often caused by a major force that separates your shoulder joint’s ball (the top rounded part of your upper arm bone) from your joint’s socket (glenoid). […] Your shoulder can dislocate in several ways, including: […] Forward and downward dislocation (anterior dislocation). These are the most common types of dislocations. They often result from falling on your outstretched hand or on the shoulder itself. […] Backward dislocation (posterior dislocation). This type of dislocation may be caused by a direct blow to the front of your shoulder, or the violent twisting of your upper arm. […] Shoulder dislocation means your upper arm bone has come out of your shoulder joint. […] Your shoulder can dislocate forward and downward, and backward. It can be partly or fully dislocated. […] If you had a dislocated shoulder in the past, you are at greater risk for having it happen again.

• #3 Shoulder Dislocations Overview – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK459125/

  Shoulder dislocations represent 50 percent of all major joint dislocations, with anterior dislocation being most common. The shoulder joint is the most regularly dislocated joint in the body. The shoulder can dislocate forward, backward, or downward, and completely or partially, though most occur anteriorly. Fibrous tissue that joins the bones can be stretched or torn, complicating a dislocation. It takes a strong force, such as a blow to the shoulder to pull the bones out of place. Extreme rotation can pop the shoulder out of its socket. Contact sports injuries often cause a dislocated shoulder. Trauma from motor vehicle accidents and falls are also a common source of dislocation. […] The shoulder joint is the most regularly dislocated joint in the body.

• #3 Shoulder Dislocation: Symptoms, and Treatment | Doctor

  https://patient.info/doctor/shoulder-dislocation

  Shoulder dislocation is usually anterior (95-98% of cases).1 However, posterior dislocation can sometimes occur. […] Anterior dislocation is almost invariably traumatic. It usually occurs when people fall with a combination of abduction, extension and a posteriorly directed force on the arm.2 A fall on to an outstretched hand is a common mechanism in the elderly. The humeral head is forced anteriorly, out of the glenohumeral joint, tearing the shoulder capsule and detaching the labrum from the glenoid. A fracture of the humeral head, neck or greater tuberosity can occur at the same time.3 […] Posterior dislocation is less common. It is generally caused by forces with the shoulder held in internal rotation and adduction. It may result from an epileptic fit or an electrocution or lightning injury.4 An unexplained posterior dislocation should raise the possibility of a convulsion. It can occasionally occur due to a direct blow during trauma, usually associated with sport.

  https://orthosportsmed.com/top-5-causes-of-shoulder-dislocations/

  However, no matter how strong or broad ones shoulders may be, this feature does not change the fact that a dislocated shoulder is the #1 most common joint dislocation injury. […] The compromise of freedom-of-motion over stability is what leaves the shoulder so susceptible to dislocation. More than half of all joint dislocations treated across the country are for the shoulder. […] A dislocated shoulder may occur from five common sources: sports injuries, impact injuries, falls, repetitive stress injuries (RSIs), and loose ligaments. […] Shoulder dislocations occur most commonly in sports and athletic activities, particularly those that require repeated, forceful use of the shoulder. In addition, any impact that includes a twisting motion increases the likelihood of a resulting shoulder dislocation.

• #5 Dislocated Shoulder – UOA – University Orthopaedic Associates

  https://uoanj.com/hand-upper-extremity/shoulder-dislocation-2/

  Shoulder dislocations are most commonly (about 90 percent) in the anterior direction. This is where the ball can dislocate towards the front of the body. […] A shoulder dislocation is most often caused by acute traumatic events or injuries, such as car accidents, falls, and sports injuries, especially during a contact sport such as football, rugby or lacrosse. […] Seizures can also result in shoulder dislocations due to muscle contractions pulling the humerus head out of the socket. Shoulder dislocations caused by seizures are most commonly posterior, or where the ball dislocated backwards.

• #6 Posterior Shoulder Dislocations – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK441919/

  Posterior shoulder dislocations are relatively rare, accounting for about 2% to 5% of all shoulder dislocations. They occur when the head of the humerus is displaced backward, usually due to forceful adduction combined with internal rotation or from a blunt blow to the anterior shoulder. […] The most common mechanism is forceful adduction with internal rotation, but a direct, blunt blow to the anterior shoulder may also result in dislocation. Any unexplained nocturnal posterior dislocation should prompt one to consider a seizure. […] The classic mechanisms of posterior dislocation involve tonic-clonic seizures, electrical shock, or anterior-directed shoulder trauma (such as grabbing the dashboard in a motor vehicle collision or falling on an outstretched hand). These injuries create forceful internal rotation, adduction, and shoulder flexion.

• #8 Shoulder Dislocation in Emergency Medicine: Background, Etiology, Epidemiology

  https://emedicine.medscape.com/article/823843-overview

  Rare, but serious, inferior dislocations (luxatio erecta) may be due to axial force applied to an arm raised overhead, such as when a motorcycle collision victim tumbles to the ground. More commonly, the shoulder is dislocated inferiorly by indirect forces hyperabducting the arm. The neck of the humerus is levered against the acromion and the inferior capsule tears as the humeral head is forced out inferiorly. Luxatio erecta almost always has an associated fracture or soft-tissue injury. One series found 80% of patients to have fracture of the greater tuberosity or tear of the rotator cuff. Neurologic compromise was found in 60% of patients, with the axillary nerve the most commonly injured nerve. Inferior dislocations have the highest incidence (3.3%) of vascular compromise.

• #9 Dislocated shoulder – Wikipedia

  https://en.wikipedia.org/wiki/Dislocated_shoulder

  A shoulder dislocation often occurs as a result of a fall onto an outstretched arm or onto the shoulder.[3] […] Anterior dislocations are usually caused by a direct blow to, or fall on, an outstretched arm. […] Posterior dislocations are uncommon, and are typically due to the muscle contraction from electric shock or seizure.[6] […] Inferior dislocation is the least likely, occurring in less than 1%. This condition is also called luxatio erecta because the arm appears to be permanently held upward or behind the head.[18] It is caused by a hyper abduction of the arm that forces the humeral head against the acromion.[19] Such injuries have a high complication rate as many vascular, neurological, tendon, and ligament injuries are likely to occur from this mechanism of injury.

• #13 Shoulder Dislocation: Causes, Symptoms, and Treatment Options | First State Orthopaedics in Delaware

  https://www.firststateortho.com/blog/shoulder-dislocation-causes-symptoms-treatment

  Shoulder dislocation occurs when the humerus is forced out of its socket. This can happen due to a sudden impact or trauma, such as a fall, sports injury, or car accident. The force applied to the shoulder joint overwhelms the surrounding structures, causing the humerus to come out of its normal position. […] Shoulder dislocations can occur for various reasons, but there are some common causes that are frequently seen. One of the leading causes is sports-related injuries, particularly contact sports like football, rugby, and wrestling. These activities involve high-impact collisions and falls, putting the shoulder joint at risk of dislocation. […] Another common cause is falls, especially onto an outstretched arm. When a person falls and lands on their extended arm, the impact can force the humerus out of the socket. This is often seen in elderly individuals who may have weaker bones and muscles, making them more susceptible to dislocations. […] Additionally, individuals with certain medical conditions, such as hypermobility or joint laxity, may be more prone to shoulder dislocations. These conditions cause increased flexibility in the joints, making them less stable and more susceptible to dislocation.

• #20 Chronic Shoulder Instability and Dislocation – OrthoInfo – AAOS

  https://orthoinfo.aaos.org/en/diseases–conditions/chronic-shoulder-instability/

  Shoulder instability occurs when the head of the upper arm bone is forced out of the shoulder socket. This typically happens as a result of a sudden injury, such as a fall or accident. […] Severe injury, or trauma, is often the cause of an initial shoulder dislocation. When the head of the humerus dislocates, the socket bone (glenoid) and the ligaments in the front of the shoulder are often injured. […] Some people with shoulder instability have never had a dislocation. Most of these patients have looser ligaments in their shoulders. […] Sometimes, the looseness is the result of repetitive overhead motion. Swimming, tennis, and volleyball are among the sports requiring repetitive overhead motion that can stretch out the shoulder ligaments. […] In a small minority of patients, the shoulder can become unstable without a history of injury or repetitive strain. In such patients, the shoulder may feel loose or dislocate in multiple directions, meaning the ball may dislocate out the front, out the back, or out the bottom of the shoulder. This is called multidirectional instability.

• #23 Shoulder Dislocation in Emergency Medicine: Background, Etiology, Epidemiology

  https://emedicine.medscape.com/article/823843-overview

  Anterior shoulder dislocations usually result from abduction, extension, and external rotation, such as when preparing for a volleyball spike. Falls on an outstretched hand are a common cause in older adults. The humeral head is forced out of the glenohumeral joint, rupturing or detaching the anterior capsule from its attachment to the head of the humerus or from its insertion to the edge of the glenoid fossa. This occurs with or without lateral detachment. […] Posterior dislocations are caused by severe internal rotation and adduction. This type of dislocation usually occurs during a seizure, a fall on an outstretched arm, or electrocution. Occasionally, a severe direct blow may cause a posterior dislocation. Bilateral posterior dislocation is rare and almost always results from seizure activity. Misinterpretation of the radiograph appearance of a posterior dislocation may result in misdiagnosis as a soft tissue injury in up to 79% of cases.

Dislocation is often caused by a major force that separates your shoulder joint’s ball (the top rounded part of your upper arm bone) from your joint’s socket (glenoid). […] Your shoulder can dislocate in several ways, including: […] Forward and downward dislocation (anterior dislocation). These are the most common types of dislocations. They often result from falling on your outstretched hand or on the shoulder itself. […] Backward dislocation (posterior dislocation). This type of dislocation may be caused by a direct blow to the front of your shoulder, or the violent twisting of your upper arm. […] Shoulder dislocation means your upper arm bone has come out of your shoulder joint. […] Your shoulder can dislocate forward and downward, and backward. It can be partly or fully dislocated. […] If you had a dislocated shoulder in the past, you are at greater risk for having it happen again.

  https://patient.info/doctor/shoulder-dislocation

  Shoulder dislocation is usually anterior (95-98% of cases).1 However, posterior dislocation can sometimes occur. […] Anterior dislocation is almost invariably traumatic. It usually occurs when people fall with a combination of abduction, extension and a posteriorly directed force on the arm.2 A fall on to an outstretched hand is a common mechanism in the elderly. The humeral head is forced anteriorly, out of the glenohumeral joint, tearing the shoulder capsule and detaching the labrum from the glenoid. A fracture of the humeral head, neck or greater tuberosity can occur at the same time.3 […] Posterior dislocation is less common. It is generally caused by forces with the shoulder held in internal rotation and adduction. It may result from an epileptic fit or an electrocution or lightning injury.4 An unexplained posterior dislocation should raise the possibility of a convulsion. It can occasionally occur due to a direct blow during trauma, usually associated with sport.

  Shoulder dislocation happens when the upper arm bone pops out of the shoulder joint. This injury can cause pain, swelling, and limit range of motion. […] Traumatic injuries, particularly those sustained during contact sports or accidents, are the most common cause of shoulder dislocations. […] Common causes of shoulder dislocations are: […] Sudden and forceful impacts during physical activities, such as rugby or wrestling, can cause the shoulder to dislocate. […] Falling with an outstretched hand or getting hit on the shoulder can cause shoulder dislocation. This is common in activities such as cycling, hiking, or exercising on uneven surfaces. […] Being involved in a traffic accident can result in shoulder dislocation. […] Repetitive shoulder movement, such as swinging and carrying heavy loads above your head, can weaken the shoulder joint over time, making it more susceptible to dislocation. […] Once a shoulder has dislocated, the joint and its supporting structures (ligaments, tendons, and muscles) may become weaker or damaged, making recurrent dislocations more likely.

• #75 3 Causes of Shoulder Instability

  https://www.sports-health.com/blog/3-causes-shoulder-instability

  Shoulder trauma from accidents or acute injury: Motor vehicle accidents result in aggressive shoulder dislocations as the body is thrown about. […] Dislocation imparts tears to the capsule and ligaments that stabilize the shoulder as the arm is driven out from its stable position. […] Traumatic shoulder instability is typically common in young athletes and men and accounts for more than 95% of all cases. […] Minor repetitive strains that develop over time progressively stretch the shoulder’s stabilizers, such as ligaments and tendons. […] Overuse injury from sports: Swimmers, pitchers, and volleyball players perform thousands of overhead motions while participating in the respective sport, making the shoulder joint vulnerable to overuse injury. […] Overuse injury from work: Using an unsupported posture while lifting or carrying heavy loads overhead contributes to a risk of shoulder joint instability.

  Shoulder instability can have several causes, including: […] For many patients, an injury that causes a dislocated shoulder can lead to chronic shoulder instability. Work-related or sports injuries are both leading causes of dislocated shoulder and shoulder instability. […] Repeated overhead motion can cause loosening of the connective tissues in the shoulder. Sports that require this type of motion, including volleyball, swimming and tennis, are common causes of shoulder instability. Job activities that involve mechanical work or repetitive lifting can also cause shoulder problems. […] Some people naturally have loose ligaments in their shoulders, causing instability unrelated to injury or repetitive strain.

  A dislocated shoulder may occur from five common sources: sports injuries, impact injuries, falls, repetitive stress injuries (RSIs), and loose ligaments. […] Shoulder dislocations occur most commonly in sports and athletic activities, particularly those that require repeated, forceful use of the shoulder. […] Significant force is required to pull the humerus out of its socket, and to overcome the cushioning and shock absorption abilities of the tissues of the joint capsule. […] With this dislocation, the shoulder has been subjected to a strong traumatic force, one powerful enough to have pulled the shoulder out of joint. […] This type dislocation, the shoulder dislocates with little force, caused by everyday activities like reaching for something on a high shelf, or rolling onto the shoulder in bed. […] The connective tissue in the shoulder that normally keeps the head of the upper arm bone in the shoulder socket may become loose due to injury, overuse, or from previous shoulder dislocations.

  https://your-shoulder.com/dislocated-shoulder-symptoms-treatment/

  What causes a shoulder dislocation? There are several reasons why a shoulder may dislocate and they can be broadly put into 3 groups […] In this type of dislocation there is usually a significant injury that has transmitted enough force through the shoulder joint to cause it to dislocate. There is usually damage to the structures inside the shoulder. […] In this type of dislocation there is usually little force and often no injury at all. Some patients report that simply throwing a duvet over the bed can cause a dislocation. […] These dislocations occur because the several muscles that help to stabilise the shoulder are not coordinating or working properly and cannot hold the humeral head in joint. This may be due to issue with the muscle itself or the nerves that power those muscles.

• #97 Shoulder Dislocation in Emergency Medicine: Background, Etiology, Epidemiology

  https://emedicine.medscape.com/article/823843-overview

  Rare, but serious, inferior dislocations (luxatio erecta) may be due to axial force applied to an arm raised overhead, such as when a motorcycle collision victim tumbles to the ground. More commonly, the shoulder is dislocated inferiorly by indirect forces hyperabducting the arm. The neck of the humerus is levered against the acromion and the inferior capsule tears as the humeral head is forced out inferiorly. Luxatio erecta almost always has an associated fracture or soft-tissue injury. One series found 80% of patients to have fracture of the greater tuberosity or tear of the rotator cuff. Neurologic compromise was found in 60% of patients, with the axillary nerve the most commonly injured nerve. Inferior dislocations have the highest incidence (3.3%) of vascular compromise.

• #98 Shoulder Dislocation: Symptoms, and Treatment | Doctor

  https://patient.info/doctor/shoulder-dislocation

  Shoulder dislocation is usually anterior (95-98% of cases).1 However, posterior dislocation can sometimes occur. […] Anterior dislocation is almost invariably traumatic. It usually occurs when people fall with a combination of abduction, extension and a posteriorly directed force on the arm.2 A fall on to an outstretched hand is a common mechanism in the elderly. The humeral head is forced anteriorly, out of the glenohumeral joint, tearing the shoulder capsule and detaching the labrum from the glenoid. A fracture of the humeral head, neck or greater tuberosity can occur at the same time.3 […] Posterior dislocation is less common. It is generally caused by forces with the shoulder held in internal rotation and adduction. It may result from an epileptic fit or an electrocution or lightning injury.4 An unexplained posterior dislocation should raise the possibility of a convulsion. It can occasionally occur due to a direct blow during trauma, usually associated with sport.

  A dislocated shoulder occurs when the top part of the upper arm bone partially or fully comes out of the socket. […] A force placed on the shoulder joint when it is in a vulnerable position can result in a dislocated shoulder. […] Possible causes include: a fall, a car accident, being hit during a contact sport. […] The shoulder can dislocate forward, backward, or downward. Forward dislocations, also called anterior dislocations, account for about 97% of all cases. […] An anterior dislocation usually occurs when the arm is out to the side and rotated backward, such as when throwing a ball, and then hit. As the bone exits the socket, it causes damage to the surrounding tissues that help stabilize the joint. […] A fracture of the glenoid that sometimes occurs when the shoulder dislocates is also a risk factor for recurrent dislocations. […] The dislocation is painful and can temporarily cause limited mobility. If a person does not receive proper treatment, recurrent dislocations and potential long-term problems, such as arthritis, may arise.

  The incidence of glenohumeral joint is as high as 24 per 100,000 persons annually. […] This dislocation results from contact sports, falls, bicycle accidents, and similar high-impact trauma. […] A combined force of abduction, extension, and external rotation on the shoulder causes an anterior shoulder dislocation, which constitutes about 90% of dislocations. […] Posterior dislocations can also occur from a posteriorly directed force on a flexed shoulder, or from an electric shock or seizure injury. […] Dislocation of the shoulder is often associated with damage to the joint capsule and this can lead to instability and predispose to recurrent dislocation. […] One review found a 39% risk of recurrent instability following a first-time traumatic anterior shoulder dislocation. Increased risk of recurrent instability was reported in people aged 40 years and under, in men and in people with hyperlaxity. Decreased risk of recurrent instability was reported in people with a greater tuberosity fracture. The rate of recurrent instability decreased as time from the initial dislocation increased. Other factors – such as a bony Bankart lesion, nerve palsy and occupation – influenced rates of recurrent instability.
