Shoulder arthroplasty in patients with a prior anterior shoulder dislocation. Results of a multicenter study.
Prior reports of shoulder arthroplasty performed for dislocation-induced arthropathy have included only patients who had had a prior stabilizing procedure. The purpose of this study was to report the results of shoulder arthroplasty in all patients with a prior anterior shoulder dislocation, including both those previously treated operatively and those previously treated nonoperatively. ⋯ This investigation documented the good results obtainable with shoulder arthroplasty for the treatment of arthritis following anterior shoulder instability. In addition, our findings suggest that capsulorrhaphy-induced arthropathy may be indistinguishable from arthritis following nonoperatively treated anterior shoulder instability.

Arthroscopic posterior labral repair and capsular shift for traumatic unidirectional recurrent posterior subluxation of the shoulder.
The purpose of this study was to evaluate the results of arthroscopic treatment of traumatic unidirectional recurrent posterior subluxation of the shoulder. ⋯ Arthroscopic posterior labral repair and capsular shift to treat traumatic unidirectional recurrent posterior subluxation is a reliable procedure with respect to providing stability, pain relief, and functional restoration.

Comparative StudyA single percutaneous injection of recombinant human bone morphogenetic protein-2 accelerates fracture repair.
Recombinant human bone morphogenetic protein-2 (rhBMP-2), surgically implanted with a matrix material, has been shown to induce bone formation and enhance fracture repair. The purpose of this investigation was to test the hypothesis that a single, local, percutaneous injection of rhBMP-2 would accelerate fracture-healing in a standard rat femoral fracture model. ⋯ These data demonstrate that a single, local, percutaneous injection of rhBMP-2 accelerates fracture repair in this rat femoral fracture model. This effect appears to result from a combination of the induction of bone formation at the fracture site and acceleration of the rate at which the fracture callus matures.
