A rare case of a fracture through the neck of the talus with a trimalleolar ankle fracture and ruptured tibialis posterior tendon is presented and the literature reviewed. Management consisted of open-reduction internal fixation of the fractures and repair of the tibialis posterior tendon. At 40 months after injury, the patient had tibiotalar range of motion at 5 degrees of dorsiflexion and 38 degrees of plantar flexion. While avascular necrosis of the talus did not occur, significant degenerative arthritis of the ankle was noted.

Comparative Study
Operative management of displaced femoral head fractures: case-matched comparison of anterior versus posterior approaches for Pipkin I and Pipkin II fractures.
Because of the controversy surrounding the selection of the surgical approach for the operative management of femoral head fractures, we retrospectively reviewed the combined experience with femoral head fractures at two major trauma centers. Forty-three femoral head fractures in 41 patients were identified. Twenty-six of the 43 fractures were Pipkin types I and II, and were managed operatively. ⋯ The functional results in the two groups were identical; 67% good and excellent in each. There were no cases of avascular necrosis of the femoral head associated with an anterior approach. Because of the greater ease of access to the fracture, the anterior approach is recommended when operative reduction of a displaced Pipkin type I or II is indicated, but newer methods of minimizing heterotopic ossification must be developed.

Seventeen patients, aged 11-67 years (mean, 32.6), with major vascular injuries associated with traumatic orthopaedic injuries, were treated operatively in the authors' institution over a 4-year period. The most common mechanism of trauma was a high-energy injury (70.8%), and the rate of open injuries was 88.2%; 64.9% of the injuries were located in the lower extremities. The treatment protocol consisted of aggressive resuscitation; Doppler imaging and, when necessary, angiography; stable bone fixation with subsequent vascular repair; and extended wound debridement. ⋯ Although six patients (35.4%) were admitted with delayed shock (mean duration, 73.6 +/- 27.8 min), this led to a lethal outcome due to shock lung in only one patient. Another patient developed massive lung embolism 3 months postoperatively and died. The authors believe that this well-organized approach, based on a specific treatment protocol, for patients with severe orthopaedic trauma and concomitant vascular injury, not only improves outcome but gives good to excellent functional results in the majority of patients.

Proximal radioulnar transposition in an elbow dislocation is rare. Only three cases have been recorded. ⋯ Proximal radioulnar translocation has been believed to be iatrogenic. The injury we report was not iatrogenic, and mechanical locking of radial head and neck fracture necessitated open reduction.

A prospective study on tension band fixation of medial malleolus fractures was performed on 30 consecutive patients with 31 fractures from October 1987 until December 1990. All patients had at least a displaced medial malleolus fracture unreduced by closed methods. The fractures were classified into small, medium and large using a modified Lauge-Hansen classification. ⋯ The tension band fixation provided the greatest resistance to pronation forces: for times stiffer than the two screws and 62% of the intact specimen. Tension band fixation of the medial malleolus is a biomechanically strong and clinically acceptable method of treatment for displaced medial malleolus fractures. This method of fixation may be especially useful for small fragments and in osteoporotic bone.
