Femoral-sided fracture-dislocation of the knee.

OBJECTIVE: To document a previously undescribed fracture-dislocation of the knee that involves a femoral condyle and associated ligaments yet spares the tibial joint surface. DESIGN: Retrospective. SETTING: University. PATIENTS: Four cases of fracture-dislocation of the knee that involve ligamentous injury and fracture of the femoral condyle(s). RESULTS: At a minimum two-year follow-up (average 28.8 months, range 26 to 37 months), overall functional outcome is only fair to good in this injury pattern. The Lysholm knee rating averaged 60 (range 39 to 74) and KT-1000 I-N testing averaged three millimeters at thirty pounds. CONCLUSION: Despite treatment of this fracture-dislocation with internal fixation of the femoral condyle(s) and repair of the ligament(s), functional deficits occur in this severe knee injury patterns.

Successful revascularization of a partially avulsed foot in a 6-year-old child.

The foot of a 6-year-old child was revascularized successfully following an avulsion and partial amputation through the tibiotalar joint. Partial degloving had disrupted the anterior and posterior tibial arteries with resultant ischemia. We excised the entire damaged segment of the posterior tibial artery and performed a reverse saphenous vein graft, end-to-end reconstruction of the defect. Peroneal and tibial nerve function returned within 5 months. Four years later, the patient has regained full, painless range of motion and normal strength and sensibility with no evidence of premature growth plate closure or avascular necrosis of the talus.

Excision of ununited fractures of the posterior process of the talus: a treatment for chronic posterior ankle pain.

The cases of nine patients with ununited fracture of the posterior process of the talus were reviewed. The most common mechanism of injury was forced plantarflexion. All patients had pain in the posterior ankle region. Common physical findings included tenderness between the lateral malleolus and the Achilles tendon and pain on forced plantarflexion. Of the radiographic imaging modalities used, 99Tc bone scan was found to be the most helpful in diagnosis. All nine patients eventually underwent surgical excision at a mean period of 9.4 months post injury. At average follow-up of 27 months after surgery (range 7-69 months), six of nine patients had good or excellent results with respect to pain relief and return to function. There were two complications of sural neuroma formation, one of which resulted in severe persistent pain after surgery. Based on these findings, we believe the differential diagnosis of chronic posttraumatic ankle pain should include fracture of the posterior process of the talus. Furthermore, excision of an ununited fragment through a lateral approach, taking care to preserve and protect the sural nerve, should lead to the return of painless function in the majority of cases.

Growth disturbance of the distal radial epiphysis after trauma: operative treatment by corrective radial osteotomy.

Growth disturbance owing to partial posttraumatic closure of the distal radial physis is rare. The resulting painful, stiff wrist often requires operative treatment. Problems with the operative technique are presented in this case report; different operative techniques described in the literature are discussed. Our technique, described in the literature are discussed. Our technique, osteotomy of the distal radius with interposition of a tricortical bone graft, allows the surgeon to restore the normal longitudinal relationship between the radius and ulna and to reorient the distal radial articular surface to achieve a normal radiocarpal and radioulnar relationship. The patient experiences improved painless wrist motion as a result of this technique.
