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.
