Posterior Shoulder Dislocation

The shoulder joint is not a deep ball-and-socket joint, and the curved humeral head and the relatively flat glenoid make the shoulder joint inherently unstable.  The attorneys at McAleer Law are here to guide you through the sometimes complex arena of personal injury law, including cases involving car accidents, boating accidents and ATV accidents. Contact an Alabama personal injury attorney as soon as possible if you have suffered an injury in an accident.

Posterior shoulder instability probably represents less than 5% of shoulder dislocations.  Regardless of cause, a predisposition to posterior instability is typically multifactorial in nature. It is usually associated with a combination of abnormal bony anatomic factors, soft tissue abnormalities or imbalances, pathologic joint lesions or disruption of capsuloligamentous structures. Furthermore, one must differentiate between shoulder laxity, which is a physiological variant of normal, and true shoulder instability, which is a symptomatic, pathologic process.

Bony anatomic deformities that have been implicated include increased humeral retroversion, glenoid retroversion and glenoid hypoplasia.  Soft tissue abnormalities or imbalances may be the result of excessive capsular laxity, with a large capsular recess, or neuromuscular imbalance, such as a neonatal brachial plexus injury. Pathologic lesions, such as a posterior labral tear or loss of integrity of the inferior glenohumeral ligament, may also be predisposing factors.

While acknowledging the potential predisposing factors, posterior instability is thought to be secondary to 3 types of etiologic process: (a) major injury, (b) repetitive minor trauma, or (c) a virtually atraumatic process.
