INTRODUCTION Though proximal humeral physeal injuries are common in children, reports of proximal humeral physeal injuries with disruption of glenohumeral joint are exceedingly rare. We here report such a case. CASE REPORT A three year old male patient presented to us with proximal humeral physeal separation along with glenohumeral dislocation. Under general anaesthesia, closed reduction coul...

[Purpose] Glenohumeral posterior capsule tightness possibly relates to posterior capsule thickness (PCT). The purpose of the current study was to analyze the relationships between PCT and glenohumeral range of motion (ROM) in horizontal adduction (HAdd) and internal rotation (IR). [Subjects and Methods] This study recruited 39 healthy collegiate baseball players. We measured PCT by using ultras...

Subacromial shoulder pain is commonly located to the top and lateral side of the shoulder. It is exaggerated by overhead activity and can be associated with night pain. It is usually associated with full passive range of movement of the glenohumeral joint. The pain originates from the subacromial space of the shoulder, an area made up of the rotator cuff tendons and the subacromial bursa. This ...

This study compared the effect of a computer-assisted and a traditional surgical technique on the kinematics of the glenohumeral joint during passive abduction after hemiarthroplasty of the shoulder for the treatment of fractures. We used seven pairs of fresh-frozen cadaver shoulders to create simulated four-part fractures of the proximal humerus, which were then reconstructed with hemiarthropl...

PURPOSE To review the anatomy of the shoulder joint and of the physiology of glenohumeral stability is essential to manage correctly shoulder instability. METHODS It was reviewed a large number of recently published research studies related to the shoulder instability that received a higher Level of Evidence grade. RESULTS It is reviewed the bony anatomy, the anatomy and function of the lig...

Wheelchairs are the primary mobility device for individuals having difficulty with ambulatory activities [1]. In the U.S. it is estimated that 3.3 million people used a wheelchair in 2010 [2], of which 90% used manual wheelchairs (MWs) [3]. However, MWs often lead to reduced independent function and quality of life [4]. Furthermore, shoulder pain and injuries are commonly associated with MW pro...

BACKGROUND The glenohumeral joint becomes dislocated more than any other major joint because it maintains a wide range of motion and its stability is inherently weak. The most common complication following acute initial shoulder dislocation is recurrent dislocation or chronic instability. Imbalance of strength and range of motion in individuals with anterior dislocation can be a contributing fa...

The goal of this article is to present a concise review of the current concepts of shoulder instability. This chapter supplements the radiologic assessment of glenohumeral instability, which follows this section.

Recent research findings are incorporated in this review of the functional anatomy of the shoulder complex. The scapulothoracic mechanism is described, including a review of scapular motion and the structure and function of the sternoclavicular and acromioclavicular joints. New information regarding the resting position of the scapula on the thorax and the effect of aging and spinal posture on ...

Anterior glenoid bone loss is present in nearly all cases of recurrent anterior glenohumeral instability. Treating glenoid bone loss in the setting of recurrent instability is challenging, and often, soft tissue stabilization procedures in isolation are inadequate. The nonanatomic, incongruous joint resulting from most bony augmentation procedures has motivated investigators to find an alternat...
