Stress-riser fractures of the hip after sliding screw plate fixation.

Fractures occurring after fixation of intertrochanteric femur fractures have been described previously in the literature. Terms such as "stress-riser fracture" and "Young's modulus fracture" have been applied. The prevalence of these fracture types has increased, and so has use of the sliding screw plate device for fixation of intertrochanteric hip fractures.

Bilateral simultaneous infrapatellar tendon rupture: support for Davidsson's theory.

Rupture of the extensor mechanism of the knee is not an unusual occurrence. Bilateral simultaneous rupture, however, is rare. Most cases of bilateral simultaneous rupture occur in association with systemic disease, i.

Immediate double hip spica immobilization as the treatment for femoral shaft fractures in children.

Fractures of the femur in children are usually the result of high-velocity injury. Older methods of treatment, i.e.

Use of the infrapatella strap in the treatment of patellofemoral pain.

The spectrum of patellofemoral disorders ranging from chondromalacia of the patella to degenerative arthritis is a difficult, often vexing problem. Many methods of treatment, both surgical and nonsurgical, have been used without uniform or predictable success. The infrapatella strap, a new concept in nonsurgical management of patellofemoral pain, can be effective in 77% of patients.
