Our findings confirm the view that anatomic repair of distal biceps tendon rupture provides consistently good results and early anatomic reconstruction can restore strength and endurance for the elbow.

Primary synovial chondromatosis is an uncommon condition, and involvement of the glenohumeral joint is rare. Currently, the recommended treatment is arthroscope-assisted synovectomy and removal of the loose bodies. We report a case with the clinical findings, radiographic features, arthroscopic technique for treatment of this disease and the main histological appearance of the removed loose bodies. We believe this is an easy and safe method for management of this disorder and that the support of an experienced pathologist is necessary to avoid differential diagnostic problems with the uncommon malignant transformation.

INTRODUCTION:\ud Latissimus dorsi tendon transfer (LDT) is a recent method for surgical treatment of massive, irreparable posterosuperior cuff tears (MIPCT). So far, there are no studies on the quantitative motion analysis of the shoulder and latissimus dorsi (LD) muscle activation after LDT. The changes in shoulder movements after LDT can be objectively assessed by the 3-D motion analysis. These changes may not be due to an increased activity of the LD muscle as external rotator.\ud MATERIALS AND METHODS:\ud The shoulder kinematics of nine patients with MIPCT were recorded through a 3-D motion analysis system, before LTD (T0), and after 3 (T1) and 6 (T2) months post-LDT. Maximal shoulder flexion-extension, abduction-adduction, and horizontal abduction-adduction, and the internal and external circumduction of the shoulder joint were measured during upright standing posture. Surface EMG activity of the LD muscle was recorded during both internal rotation (IR) and external rotation (ER) tasks in three different postures.\ud RESULTS:\ud A significant increase of shoulder movements was observed at T2 compared with T0 for almost all motor tasks. A significant effect of LDT was also found on LD-IR/ER ratio in posture 1 at T2 compared with T0 and T1. No significant effects were found for the LD-IR/ER ratio in the other postures.\ud CONCLUSIONS:\ud Our study indicates that LDT is effective in shoulder motion recovery. Such improvement is not associated with a change in function of the LD muscle, which may be induced by a depression of the humeral head into the glenoid cavity instead
