ReviewAlternative bearings in total hip arthroplasty in the young patient.
Total hip arthroplasty is an effective treatment option for advanced hip arthritis in elderly patients. Studies in young patients have traditionally shown less durable results. ⋯ To improve implant longevity, there are several bearing surface choices currently available for this demanding group of patients. Alternatives must be evaluated in terms of the risks and benefits associated with each articulation, and all new technologies must be carefully monitored over the long term.

ReviewThe evolution of damage control orthopedics: current evidence and practical applications of early appropriate care.
This article summarizes the evolution of literature and practice related to fracture care in polytrauma patients. Particular emphasis is given to the management of femoral shaft fractures and the concept of damage control in these complex patients. The application of these guidelines in common clinical practice is also discussed.

ReviewRadial head fractures: indications and outcomes for radial head arthroplasty.
Radial head fractures without associated bony or ligamentous injury can be safely treated with internal fixation, if possible, or arthroplasty if nonreconstructable. However, nonreconstructable radial head fractures in association with elbow dislocation and/or ligamentous injury in the elbow or forearm represent a specific subset of injuries that requires restoration of the radiocapitellar articulation for optimal function. The purpose of this article was to summarize the indications for radial head arthroplasty and discuss the reported outcomes.

ReviewManagement of radial nerve palsy following fractures of the humerus.
Radial nerve palsy is the most common peripheral nerve injury following a humerus fracture, occurring in 2% to 17% of cases. Radial nerve palsies associated with closed humerus fractures have traditionally been treated with observation, with late exploration restricted to cases without spontaneous nerve recovery at 3 to 6 months. Advocates for early exploration believe that late exploration can result in increased muscular atrophy, motor endplate loss, compromised nerve recovery upon delayed repair, and significant interval loss of patient function and livelihood. In contrast, early exploration can hasten nerve injury characterization and repair, and facilitate early fracture stabilization and rehabilitation.

Fractures of the acetabulum are some of the most challenging fractures that face orthopedic surgeons. In geriatric patients, these challenges are enhanced by the complexity of fracture patterns, the poor biomechanical characteristics of osteoporotic bone, and the comorbidities present in this population. Nonsurgical management is preferable when the fracture is stable enough to allow mobilization, and healing in a functional position can be expected. When significant displacement and/or hip instability are present, operative management is preferred in most patients, which may include open reduction and internal fixation with or without total hip arthroplasty.
