Comparative Study
Functional outcome of glenohumeral fusion in brachial plexus palsy: a report of 54 cases.
The restoration of shoulder function is a major issue in brachial plexus palsy. Although several tendon and nerve transfers have been described, shoulder arthrodesis remains a reliable technique in this context. This study planned to compare surgical and functional outcomes of 2 glenohumeral arthrodesis bone graft techniques: massive subacromial corticocancellous versus cancellous only grafts. ⋯ Therapeutic III.

This study reports the results of restoring the deltoid and triceps functions in patients with C5, C6, and C7 root avulsion injuries by simultaneously transferring 4 intercostal nerves to the anterior axillary nerve and the nerve to the long head of the triceps through the posterior approach. ⋯ Therapeutic IV.

Vascularized composite allotransplantation is a recent innovation in the fields of transplantation surgery, plastic and reconstructive surgery, and orthopedic surgery. The success of hand and face transplantation has been based on extensive experience in solid organ transplantation. ⋯ The purpose of this article is to introduce the basics of human immunology (innate and adaptive systems) and the immunological basis of human transplantation (the importance of human leukocyte antigen, direct and indirect pathways of antigen recognition, the 3 signals for T-cell activation, and mechanisms and types of allograft rejection) and focus on the mode of action of immunosuppressive drugs that have evolved as the mechanisms and pathways for rejection have been defined through research. This includes recent studies involving the use of costimulatory blockade, regulatory T cells, and tolerance induction that have resulted from research in understanding the mechanisms of immune recognition and function.

Double-plate fixation is a popular treatment method for intercondylar humeral fractures. Ulnar nerve complications are emphasized, but radial nerve complications are rarely mentioned. We present a case of iatrogenic radial nerve palsy following open reduction and double plating of a supracondylar/intercondylar fracture of the humerus. ⋯ On exploration, a segment of nerve was found crushed within the reduced lateral condyle fracture site, with a screw from the posteroradial plate going through the nerve. Although rare, radial nerve injury can occur with posteriorly displaced supracondylar/intercondylar humerus fractures. When preoperative signs of radial nerve injury are present, we recommend that the radial nerve be identified and protected during double-plate fixation.

In this retrospective, nonrandomized study, we evaluated the clinical outcomes of percutaneous screw and K-wire fixation in the treatment of acute transscaphoid perilunate fracture dislocation. ⋯ Prognostic III.
