BACKGROUND Different implant designs are utilized in reverse shoulder arthroplasty. The purpose of this systematic review was to evaluate the results of reverse shoulder arthroplasty using a traditional (Grammont) prosthesis and a lateralized prosthesis for the treatment of cuff tear arthropathy and massive irreparable rotator cuff tears. METHODS A systematic review of the literature was perf...

Synovial chondromatosis is an uncommon condition, and involvement of the shoulder is even more rare. We report on a 39-year-old female who presented with symptoms, radiographic features, and intraoperative findings consistent with multiple subacromial loose bodies resulting in a partial-thickness, bursal-sided rotator cuff tear of the supraspinatus muscle. She was treated with an arthroscopic r...

Increases security of fixation in rotator cuff repair is usually achieved by increasing the strength of fixation. Paradoxically, the problem can be approached by techniques that decrease the strain at the margins of the tear so that weaker fixation will still be adequate. Such techniques provide greater safety tolerances for the strength characteristics of suture, tendon, and bone. The principl...

Rotator cuff lesions (RCL) have considerable variability in location, tear pattern, functional impairment, and repairability.Historical classifications for differentiating these lesions have been based upon factors such as the size and shape of the tear, and the degree of atrophy and fatty infiltration. Additional recent descriptions include bipolar rotator cuff insufficiency, 'Fosbury flop tea...

Rotator cuff (RC) disease, defined as any pathological state of the rotator cuff, is one most common shoulder conditions worldwide. It accounts for 70% pain and dysfunction in adults third prevalent musculoskeletal disorder. Currently, main issue with disease that surgery represents treatment performed. However, surgeries have a high failure rate positively correlated severity tear, re-tear rat...

Methods: A cohort of 195 subjects with an asymptomatic rotator cuff tear was prospectively monitored for pain development and examined annually for changes in various parameters such as tear size, fatty degeneration of the rotator cuff muscle, glenohumeral kinematics, and shoulder function. Forty-four subjects were found to have developed new pain, and the parameters before and after pain devel...

A rotator cuff tear causes shoulder pain and limits movement of the shoulder joint. A chronic degenerative change or impingement is the reason for a rotator cuff tear. Diagnosis is made based on medical history and, physical and radiological examinations. Other causes of shoulder pain include calcific tendinitis, degenerative arthropathy, joint dislocation, fracture, and primary or metastatic n...

The use of shoulder manipulation in the treatment of frozen shoulder remains controversial. Humeral fractures and neurological damage are the risks associated with the procedure. A concern of causing a rotator cuff tear exists but the incidence of iatrogenic rotator cuff tears is not reported. The purpose of this study was to assess the effect of shoulder manipulation for frozen shoulder on the...
