I am honored and excited to be a part of the new format of the Orthopedic Clinics of North America . Each issue will consist of cutting-edge and thorough reviews on the various subspecialties of orthopedics. I am charged with overseeing the upper extremity section, which focuses on the contemporary surgical issues involving the hand, wrist, elbow, and shoulder.
The first issue’s section on the upper extremity will review some of our foremost controversies in upper extremity fracture management, including indications for reverse total shoulder arthroplasty, the management of radial nerve palsies following humeral shaft fractures, indications and outcomes for radial head arthroplasty, the management of complex posterior elbow wounds, and indications and outcomes for total elbow arthroplasty in the management of distal humerus fractures. Last, I would like to thank the authors for their sincere efforts and excellent work in presenting a coherent and concise review of these topics.
