Multicenter StudyDirect-to-implant single-stage immediate breast reconstruction with acellular dermal matrix: predictors of failure.
Direct-to-implant single-stage immediate breast reconstruction using acellular dermal matrix is a cost-effective alternative to two-stage expander-implant reconstruction. The purpose of this study was to identify predictors of direct-to-implant single-stage immediate breast reconstruction failure, defined as need for early (≤6 months) revision surgery. ⋯ Risk, III.

Split cranial bone grafting in children younger than 3 years old: debunking a surgical myth.
In cranioplasty patients split cranial bone provides excellent structural support and fundamentally "replaces like with like." However, traditional teaching in craniofacial surgery is that cranial bone cannot be split before the age of 3 years because of the lack of diploic space. The authors have found this not to be the case and describe their experience with splitting cranial bone in children with craniosynostosis younger than 3 years. ⋯ Therapeutic, IV.

Regenerative peripheral nerve interface viability and signal transduction with an implanted electrode.
The regenerative peripheral nerve interface is an internal interface for signal transduction with external electronics of prosthetic limbs; it consists of an electrode and a unit of free muscle that is neurotized by a transected residual peripheral nerve. Adding a conductive polymer coating on electrodes improves electrode conductivity. This study examines regenerative peripheral nerve interface tissue viability and signal fidelity in the presence of an implanted electrode coated or uncoated with a conductive polymer. ⋯ The regenerative peripheral nerve interface remains viable over seven months in the presence of an implanted electrode. Electrodes with and without conductive polymer reliably transduced signals from the regenerative peripheral nerve interface. Electrodes with a conductive polymer coating resulted in recording more of the regenerative peripheral nerve interface signal.

After studying this article, the participant should be able to: (1) Determine the need for operative treatment of metacarpal fractures. (2) Describe the position of immobilization for nonoperative treatment of fifth metacarpal fractures. (3) Assess the differences between intramedullary pinning and transverse pinning of displaced metacarpal fractures. (4) Compare the advantages of plating and pinning for treatment of displaced metacarpal fractures. (5) Recognize appropriate timing and treatment of open metacarpal fractures. ⋯ The body of evidence regarding the treatment of metacarpal fractures continues to grow. Conservative management, closed reduction with percutaneous Kirschner wire fixation, intramedullary fixation, and open reduction and internal fixation with plates and/or screws are all accepted treatment modalities. The goal of this review is to highlight the most recent literature and the best evidence available for the management of metacarpal fractures.
