Irreducible dislocation of the knee.

Irreducible knee dislocation is a rare injury. This case report describes a knee dislocation in a 39-year-old male U.S. Army noncommissioned officer who was injured while playing in a softball game. Arthroscopy showed the medial collateral ligament and capsule to be locked in the intercondylar notch, covering the medial femoral condyle. Arthrotomy and open reduction were required. Staged posterior cruciate ligament reconstruction using patellar tendon autograft was later performed. Review of the magnetic resonance imaging scan showed the irreducible lesion. The diagnostic clinical and radiographic features of this unusual injury are described.

Internal fixation by the Ender method.

A new method for the intramedullary fixation of trochanteric fractures with prebent, 4.5-mm, round, semielastic nails has theoretical advantages over use of nail-plate devices. Use of the method in 25 patients suggest that it is mechanically sound, relatively easy to learn, and easier for the patient to tolerate. Operating room time is reduced and blood replacement was not necessary. No infections were encountered, and all patients who were ambulatory preoperatively remained ambulatory postoperatively.

The biomechanics of head-first versus feet-first sliding.

The two basic sliding techniques, head-first and feet-first, were analyzed kinematically with high speed cinematography. Four phases were identified with each technique: sprint, attainment of sliding position, airborne, and landing. The velocity and displacement of the center of gravity were measured with each technique. The study was primarily descriptive but demonstrated potential for injury with each technique. Further studies are needed to determine which technique is safer and faster.
