Comparative StudyMortality after distal femur fractures in elderly patients.
Hip fractures in the elderly are associated with high 1-year mortality rates, but whether patients with other lower extremity fractures are exposed to a similar mortality risk is not clear. ⋯ Level II, prognostic study. See the guidelines online for a complete description of evidence.

Comparative StudyTotal shoulder arthroplasty in older patients: increased perioperative morbidity?
More elderly patients are becoming candidates for total shoulder arthroplasty with an increase in frequency of the procedure paralleling the rise in other total joint arthroplasties. Controversy still exists, however, regarding the perioperative morbidity of total joint arthroplasty in elderly patients, particularly those 80 years of age and older. ⋯ Level III, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

The importance of the radial head to elbow function and stability is increasingly apparent. Although preservation of the native radial head is preferred, severely comminuted fractures may necessitate resection or arthroplasty. Silastic radial head arthroplasty has been condemned on the basis of several sporadic reports of silicone synovitis. However, problems of "overstuffing," cartilage wear, and motion loss are becoming apparent with metal prostheses, indicating this also is not an ideal solution. Thus, the choices remain controversial. ⋯ Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Comparative StudyCan implant retention be recommended for treatment of infected TKA?
Retention treatment is reportedly associated with lower infection control rates than two-stage revision. However, the studies on which this presumption are based depend on comparisons of historical rather than concurrent controls. ⋯ Level III, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Risk factors for revision of hip arthroplasties in patients younger than 30 years.
Numerous reports of THAs in patients younger than 30 years indicate a high risk of revision. Although risk factors for revision have been reported for older patients, it is unclear whether these risk factors are the same as those for patients younger than 30 years. ⋯ Level III, therapeutic study, case control study. See the Guidelines for Authors for a complete description of levels of evidence.
