Randomized Controlled Trial Comparative StudySuperiority of the Bryan(®) disc prosthesis for cervical myelopathy: a randomized study with 3-year followup.
The current standard of care for cervical myopathy is anterior discectomy and fusion (ACDF). Although well tolerated in the short term, this treatment might ultimately result in progressive degeneration of adjacent motion segments. Artificial disc arthroplasty offers the theoretical advantage of preservation of motion at the operative level with consequent stress reduction at adjacent levels. ⋯ Level II, therapeutic study. See the Guidelines for Authors for a complete description of the levels of evidence.

Excessive complications of open intramedullary nailing of midshaft clavicle fractures with the Rockwood Clavicle Pin.
Intramedullary clavicle fixation is a potential alternative to plate fixation. Previous studies documenting the complication rates of intramedullary clavicle fixation have demonstrated variable rates of soft tissue complications and fracture healing. ⋯ Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Randomized Controlled TrialFunction plateaus by one year in patients with surgically treated displaced midshaft clavicle fractures.
Based on short-term (1 year or less) followup, primary fixation of displaced midshaft clavicle fractures reportedly results in better function compared with that reported for nonoperative methods. Whether better function persists beyond 1 year is unclear. ⋯ Level I, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

A reliable radiographic measurement technique for extra-articular scapular fractures.
Currently, neither well-defined nor standardized measurement techniques exist for assessing deformity of extra-articular scapular fractures. To properly evaluate these injuries, compare observations across studies, and make clinical decisions, a validated measurement protocol for evaluating scapular fractures is needed. ⋯ Level IV, diagnostic study. See Guidelines for Authors for a complete description of levels of evidence.

Multicenter StudyIs reverse shoulder arthroplasty appropriate for the treatment of fractures in the older patient? Early observations.
The treatment of comminuted proximal humerus fractures in older patients is challenging. Variable values of functional outcomes scores, ROMs, patient satisfaction, and bony healing have been reported with conventional techniques, including open reduction and internal fixation, percutaneous pinning, and hemiarthroplasty. Another alternative is reverse total shoulder arthroplasty, although it is unclear whether this provides better ROM or function. ⋯ Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.
