Shoulder Dislocation вђ Orthosho There are 3 types of shoulder dislocations: anterior, posterior and inferior, which refer to the direction of displacement of the humeral head: anterior dislocations account for approximately 95% of all shoulder (glenohumeral) dislocations and result from an external rotation and abduction force: anterior dislocation. Welcome! orthosho is a new resource for (surprise surprise) orthopaedic shos. we appreciate that it can be a scary job, especially overnight, and we want to help. the team behind orthosho were in your position not very long ago. please bear with us whilst we gradually upload content. if you have any comments, suggestions, or would like to work.
Shoulder Dislocation вђ Orthosho Anterior shoulder dislocation. an 80 year old woman presents to the emergency room with severe right shoulder pain and immobility. she fell down the steps outside her house and landed on her right side two hours prior to presentation. on exam, her right arm is abducted and externally rotated. Anterior shoulder dislocation. shoulder dislocation (correctly termed a glenohumeral joint dislocation) involves separation of the humerus from the glenoid of the scapula at the glenohumeral joint. the shoulder is inherently unstable joint due to the shallow glenoid articulating with a small part of the humeral head. [1]. Posterior shoulder dislocation. in these shoulder dislocations, the humeral head is displaced posterior to the glenoid fossa of the scapula. this type of dislocation is more commonly encountered in young athletic individuals. risk factors include bony abnormalities such as glenoid retroversion or hypoplasia and ligamentous laxity. Summary. traumatic anterior shoulder instability, also referred to as tubs (traumatic unilateral dislocations with a bankart lesion requiring surgery), are traumatic shoulder injuries that generally occur as a result of an anterior force to the shoulder while its abducted and externally rotated and may lead to recurrent anterior shoulder.

Shoulder dislocations can be complete or partial, and usually occur after a trauma, such as a fall or motor vehicle collision. in a complete dislocation, the joint surfaces are completely separated. in a partial dislocation, the joint surfaces are only partially separated. a partial dislocation is also called a subluxation. The shoulder is an unstable joint due to a shallow glenoid that only articulates with a small part of the humeral head. 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.
