In 1941, Jaffe and coworkers studied a lesion with histologic appearance of fibrous stroma, pigmented deposition and histiocytic infiltration as well as giant cell, for which they named pigmented villonodular synovitis, bursitis and tenosynovitis. Thereafter many authors have discussed etiology, clinical and radiological features, pathology and treatment regarding the disease. Almost all, this disease is monoarticular and knee joint is most common site. We experienced a case of localized pigmented villonodular synovitis involving an shoulder joint which was treated by local excision and obtained good result.

OBJECTIVE: To review the research progress of bone graft resorption after Latarjet procedure for the treatment of recurrent anterior shoulder dislocation, and provide a guide for further research on bone graft resorption. METHODS: The relevant literature in recent years was extensively reviewed. The pathogenesis, classification, risk factors, clinical function impact, and management of bone graft resorption after Latarjet procedure for the treatment of recurrent anterior shoulder dislocation were summarized. RESULTS: Bone graft resorption is the common complication after Latarjet procedure for the treatment of recurrent anterior shoulder dislocation. Stress shielding and poor blood supply may contribute to the occurrence of bone graft resorption. The absence of significant preoperative glenoid bone loss, open procedure, earlier graft healing may to be the risk factors for bone graft resorption. Various assessment methods and classification systems are used to evaluate the region and severity of bone graft resorption. Partial resorption may be considered as a natural glenoid remodeling process after the surgery, but severe and complete resorption is proved to be one of the reasons for failed procedures and there is no effective measure to prevent it, except for accepting revision surgery. CONCLUSION The pathogenesis, risk factors, clinical function impact of bone graft resorption after Latarjet procedure for the treatment of recurrent anterior shoulder dislocation has not been fully elucidated and there is a lack of effective management strategies, so further clinical and basic researches are needed.

Traumatic anterior dislocation of the shoulder is one of the most common directions of instability following a traumatic event. Although the incidence of shoulder dislocation is similar between young and elderly patients, most studies have traditionally focused on young patients due to relatively high rates of recurrent dislocations in this population. However, shoulder dislocations in older patients also require careful evaluation and treatment selection because they can lead to persistent pain and disability due to rotator cuff tears and nerve injuries. This article provides an overview of the nature and pathology of acute primary anterior shoulder dislocation, widely accepted management modalities, and differences in treatment for young and elderly patients.

The glenohumeral joint is inherently unstable because the large humeral head articulates with the small shadow glenoid fossa. Traumatic anterior dislocation of the shoulder is a relatively common athletic injury, and the high frequency of recurrent instability in young athletes after shoulder dislocation is discouraging to both the patient and the treating physician. Management of primary traumatic shoulder dislocation remains controversial. Traditionally, treatment involves initial immobilisation for 4-6 weeks, followed by functional rehabilitation. However, in view of the high recurrence rates associated with this traditional approach, there has been an escalating interest in determining whether immediate surgical intervention can lower the rate of recurrent shoulder dislocation, improving the patient's quality of life. This review article aims to provide an overview of the nature and pathogenesis of first-time primary anterior shoulder dislocations, the widely accepted management modalities, and the efficacy of primary surgical intervention in first-time primary anterior shoulder dislocations.

In the past, the report of shoulder instability undergoing open shoulder stabilization had satisfactory outcomes of greater than 90%. However, the functional loss of open procedure is severe in abduction and external rotation especially. Current arthroscopic techniques for shoulder instability result in success rate equal to open surgical procedure when the labrum is properly fixed to the glenoid rim using suture anchors, the capsule is tightened, and associated bony and soft tissue pathology is addressed. The arthroscopic surgery facilitates the view within shoulder joint for more accurate diagnosis, reduces operating time, minimises postoperative pain, reduces operative morbidity, improves shoulder function, and provides the possibility to perform other procedure simultaneously. However, to accomplish a successful arthroscopic stabilization procedure and to prevent complications, numerous advanced arthroscopic skill must be mastered. Although the arthroscope provides means to visualize new lesions, the pathomechanism and biomechanical explanation is not clear yet. Further studies are necessary to develop for shoulder reconstruction.

BACKGROUNDShoulder immobilization can induce adhesion of the joint, capsular contracture or lead to the condition of frozen shoulder. However, little is known about the histological effects of immobilization on the shoulder joint. This study aimed to explore the effect of immobility on the subscapular bursa (SSB) and the joint capsular content, including the distribution of types I and III collagen, within an immobilized rat shoulder.

METHODSForty-six Sprague-Dawley rats were randomly divided into one control group (n = 6) and four immobilization groups (n = 10 in each group), in which the left shoulders were immobilized with plaster for 1, 2, 3 and 4 weeks. At the end of each time point, 2 rats from each group were euthanized and shoulders prepared for serial histological observations of the glenohumeral joints, as well as picrosirius red and immunohistochemical observation of type III collagen. Histological sections of the remaining rat shoulders were used for the immunohistochemical detection of the capsular content of types I and III collagen.

RESULTSThe hyperplastic synovium of the anterior capsule obstructed the communication between the SSB and the glenohumeral joint cavity at 2 and 3 weeks. The adhesion of the SSB appeared at 3 and 4 weeks. The quantitative and qualitative results showed that the capsular contents of types I and III collagen progressively increased at 2, 3 and 4 weeks, and that type III collagen was distributed extensively within the joint capsule at 2 and 3 weeks.

CONCLUSIONImmobilization of the rat shoulder induced synovial hyperplasia of the joint capsule, adhesion of the SSB and an increase of the capsular content of types I and III collagen.

Arthroscopic repair of an isolated teres minor tendon tear without associated shoulder joint pathology has not been reported in the literature. We report on a case of isolated teres minor tendon tear after trauma. The patient complained of severe shoulder pain and progressive limited range of motion 4 months after the injury. Magnetic resonance imaging showed a full-thickness tear of the teres minor tendon at its musculotendinous junction and arthroscopic repair was performed. At 2 years follow-up, satisfactory clinical and radiological outcomes were observed with return to pre-injury level. Here, the authors report this case and provide a review of literature.
