Segmental forearm fractures are rare in children, and management is controversial. Epiphyseal injuries further complicate matters. ⋯ The patient underwent immediate internal fixation of the forearm fractures and delayed fixation of the scaphocapitate fractures. Results at 12 months showed excellent functional outcome.

Neurologic injuries are a potentially devastating complication of total hip arthroplasty (THA). Review of the literature reveals that these injuries are uncommon. The reported incidence ranges from 0.08% to 7.6%. ⋯ Reported etiologies include intraoperative direct nerve injury, significant leg lengthening, improper retractor placement, cement extravasation, cement-related thermal damage, patient positioning, manipulation, and postoperative hematoma. Risk factors include developmental dysplasia of the hip, the female sex, posttraumatic arthritis, and revision surgery. However, no single risk factor has been consistently reported to be significant, and many patients with no known risk factors incur neurologic injuries.

Osteoarthritis (OA) has become one of the leading causes of disability in the United States. Mechanical forces exerted on the joints are a significant cause of OA and one of the most modifiable risk factors. As determined by body mass index (BMI), 34 million US adults are obese, and 13 million of these are morbidly obese. ⋯ March and Bagga (Med J Aust. 2004; 180 (5 suppl): S6-S10) showed that the risk for knee OA increased by 36% for every 2 units of BMI (5 kg) of weight gain. Bariatric surgery results in a mean weight loss of 44 kg (97 lb). Eighty-nine percent of patients had complete relief of pain caused by OA in at least one joint after undergoing bariatric surgery.
