Subtrochanteric fractures of the femur below an arthritic hip are uncommon and challenging to orthopedic surgeons. Most of these fractures occur in elderly patients with advanced osteoporosis. The treatment choices consist of treatment of the fracture and the above hip joint versus treatment of the fracture alone. ⋯ Radiographic findings demonstrated stable ingrowth of the femoral prosthesis with no evidence of subsidence in 11 hips (92%). The average Engh score for all femora was 20.2 (range, 10-26). There was no relationship between the bone morphology (Dorr type) of the femoral medullary canal and the bone ingrowth scores of Engh (P=.639).

Slipped capital femoral epiphysis is a relatively common disorder in late childhood and early adolescence, with an incidence in the United States of approximately 10 per 100,000. Although clinicians have theorized that contributing factors to the development of slipped capital femoral epiphysis include 25-hydroxyvitamin D deficiency and other nutritional deficiencies, the roles of these factors have not been fully analyzed. This article presents a case of a morbidly obese 13-year-old African-American boy who presented with sudden worsening of chronic hip pain and was diagnosed with stable, bilateral, grade-III slipped capital femoral epiphysis and severe vitamin D deficiency. ⋯ Although the osteotomy provided substantial biomechanical advantage by changing the forces across the physis from shear to compressive, correction of the vitamin D deficiency was critical in providing metabolic capacity for bone healing. Vitamin D plays an important role in bone formation and development, but the level of 25-hydroxyvitamin D is not routinely measured during assessment and treatment of slipped capital femoral epiphysis patients. The early detection and proper treatment of vitamin D may assist in the treatment of patients with slipped capital femoral epiphysis.

This article describes the effect of closed reduction and internal fixation with 3 different screw configurations for acute completely displaced femoral neck fractures in young adults. From 2001 to 2006, 136 patients (age range, 20-50 years) who had acute unilaterally completely displaced femoral neck fractures were evaluated retrospectively. All fractures were managed with closed reduction and internal fixation with 3 cannulated screws. ⋯ The average duration from injury to surgery was 17.3 hours in the avascular necrosis of the femoral head group and 22.3 hours in the non-avascular necrosis of the femoral head group, with no statistical significance (P=.155). Vertical- and separated-type screw configurations resulted in a significantly higher nonunion rate (P=.001 and P=.0017, respectively) than parallel configuration. The complication rate in treating completely displaced femoral neck fractures with internal fixation in young adults is high, and screw configuration may further affect results.

Case Reports
Acute compartment syndrome of the foot following fixation of a pilon variant ankle fracture.
Acute traumatic compartment syndrome of the foot is a serious potential complication after fractures, crush injuries, or reperfusion injury after vascular repair. Foot compartment syndrome in association with injuries to the ankle is rare. This article presents a case of acute compartment syndrome of the foot following open reduction and internal fixation of an ankle fracture. ⋯ Emergently, fasciotomy of both compartments was performed through a medial incision. Postoperatively, the patient reported immediate pain relief. At 18-month follow-up, she reported no pain and had returned to all of her preinjury athletic activities.
