Midterm results of osteochondral lesions of the talar shoulder treated with fresh osteochondral allograft transplantation.
With osteochondral lesions of the talar shoulder, their size, the articular cartilage geometry, and the loss of the medial or lateral articular buttress often preclude treatment with traditional osteochondral autograft techniques. We hypothesized that fresh, large osteochondral allograft transplantation is a viable treatment option for patients with such lesions. ⋯ These midterm results in a small group of patients indicate that structural fresh allograft transplantation can be a successful surgical option in the treatment of large osteochondral defects of the talar shoulder [corrected].

Randomized Controlled Trial Comparative StudyEffect of calcium phosphate bone cement augmentation on volar plate fixation of unstable distal radial fractures in the elderly.
Calcium phosphate bone cement increases the stability of implant-bone constructs in patients with an osteoporotic fracture. The purpose of this randomized study was to determine whether augmentation of volar locking plate fixation with calcium phosphate bone cement has any benefit over volar locking plate fixation alone in patients older than sixty-five years of age who have an unstable distal radial fracture. ⋯ Augmentation of metaphyseal defects with calcium phosphate bone cement after volar locking plate fixation offered no benefit over volar locking plate fixation alone in elderly patients with an unstable distal radial fracture.

Risk factors for chondrolysis of the glenohumeral joint: a study of three hundred and seventy-five shoulder arthroscopic procedures in the practice of an individual community surgeon.
Glenohumeral chondrolysis is a complication of arthroscopic shoulder surgery characterized by the dissolution of the articular cartilage of the glenoid and the humeral head. An analysis of 375 intra-articular shoulder arthroscopic surgical procedures by an individual community orthopaedic surgeon was performed to explore which factors or combinations of factors might be associated with glenohumeral chondrolysis. ⋯ To our knowledge, this is the first Level-II retrospective cohort study of the factors associated with the development of post-arthroscopic glenohumeral chondrolysis. In this cohort of intra-articular shoulder arthroscopic procedures, chondrolysis was observed only in cases in which either Marcaine or lidocaine had been infused into the joint during the postoperative period. Avoiding such a postoperative infusion may reduce the risk of chondrolysis.
