Rehab and recovery of posterior shoulder dislocations? I'm finding quite a bit on the Internet about anterior shoulder dislocations but not much about posterior dislocations.

Acromioclavicular AC joint dislocation is a common shoulder problem. However, information about the basic epidemiological features of this condition is scarce.
The aim of this study is to analyze the epidemiology of isolated AC dislocation in an urban population. A retrospective database search was performed to identify all patients with an AC dislocation over a 5-year period.
Gender, age, affected side and traumatic mechanism were taken into account. A total of patients, with a mean age of The estimated incidence was 1.
The most common traumatic mechanism was sport injury and the most common type of dislocation was Rockwood type III. Age between 20 and 39 years and male sex represent significant demographic risk factors for AC dislocation. AC joint dislocations can result from both direct and indirect trauma.
Direct trauma is caused by a vertically oriented superior impact on the lateral part of the shoulder, forcing the AC joint in an inferior direction [ 9 ]. Indirect trauma generally results from falling on an adducted and outstretched arm causing the humeral head to be driven into the inferior aspect of the acromion and the joint itself [ 10 ].
The severity of this condition is directly related to the force of impact. AC joint dislocations range from a simple sprain of the acromion-clavicular and coraco-clavicular ligaments, which are responsible of holding the joint in its physiological position without displacement, to widely displaced injuries with dislocations of the distal third of the clavicle after the delta-trapezial fascia [ 10 ].
AC dislocations are classified on the basis of the radiographic findings. Different classification systems are available [ 1112 ], being that of Rockwood et al. The Rockwood classification takes into account not only the acromioclavicular joint, but also the coracoclavicular ligament, the deltoid and trapeziusmuscles, and the direction of dislocation of the clavicle with respect to the acromion.
According to this classification, AC dislocations can be divided into 6 types. Despite the large amount of the literature regarding the prognosis and treatment of AC dislocation, there is scarce information regarding the basic epidemiological features of this condition in the general population.
Some information can be gathered from studies based on sport practitioners [ 4 — 7 ], but, to our knowledge, there is only one study up to date that assessed the incidence of AC dislocation in a city-like population wherein only 19 cases were reported during a 1-year period [ 13 ].
The aim of this study is to analyze the epidemiology of isolated AC dislocation in an urban population during a 5-year period.A shoulder may dislocate after a significant injury like a fall on an outstretched hand or due to a direct blow to the shoulder (traumatic dislocation), or it may dislocate without a significant injury (atraumatic dislocation) in patients who have an inherent laxity of joints (loose jointed patients).
shoulder was points (range, to points), whereas the functional score, unadjusted for age or sex as a percentage of the unaffected shoulder, was %. A posterior dislocation should be considered as a differential in any episode of shoulder pain and immobility after a seizure.
Incidence The shoulder joint is the . Acute posterior shoulder dislocations are less common than anterior dislocations, but more commonly missed 50% of traumatic posterior dislocations seen in the emergency department are undiagnosed Epidemiology.
Shoulder Dislocation Shoulder Dislocation Classifications (caninariojana.com) Definition: Separation of the humerus from the scapula at the glenohumeral joint. Know the causes, symptoms, treatment, prognosis, pathophysiology, epidemiology and diagnosis of Glenohumeral arthritis.
Recurrence of traumatic incidences like fracture or shoulder dislocation, affects the articulating cartilage in the shoulder leading to progressive damage to the joint.
