Compression arthrodesis of the knee and ankle with the Hoffmann external fixator.

We performed 12 arthrodeses of the knee and eight of the ankle, using the Hoffmann device as a compressor-fixator. For the knees, the double rectangular frame was used with the added fixation of a cylinder cast in six cases. In four cases a separate half frame was used in the anterior plane. Posttraumatic arthritis was the indication in seven cases, and failed arthroplasties in five cases (three of them infected). For the ankles, a double triangular compression frame was used, with transfixing pins across the talus (after trauma) or the calcaneus (after ankle replacement). The ankle arthrodeses were done for posttraumatic arthritis in five cases (ankle fracture in one case, pylon fracture in three cases, fracture of the talus in one case), and failed ankle arthroplasty in three cases. Solid union occurred in all but one of the knee arthrodeses and in all but two of the ankle arthrodeses. Two infected total ankle replacements eventually terminated in amputation.

Open fractures of the tibia treated by the Hoffmann external fixator.

In a prospective study 40 consecutive patients with open tibial fractures were treated by the Hoffmann external fixator; the follow-up period was 18 months. All fractures were irrigated, debrided, and fixed rigidly with the Vidal-Adrey modification of the Hoffmann device as soon as the patients' condition allowed. The wounds were left open, to be closed secondarily with skin grafts, muscle flaps, and other plastic surgical procedures. The 40 wounds were all classified as Gustilo's Type II or III in relation to soft tissue damage; 36 injuries were due to motor vehicle accidents and four to gunshot wounds. At the 18-month follow-up examination there had been five amputations and five nonunions had healed after bone grafting; in addition, five patients had persistent pin drainage. Pin site drainage (80%) was the most common problem, but most cleared after removal of the fixator and five after curettage of ring sequestra. There was a high number of associated surgical procedures (2.4% per patient) related to the open fracture. At the 18-month follow-up examination bony healing was noted in all patients.

Open fractures of the tibia treated with the Lottes nail.

Of fifty consecutive open fractures of the mid-part of the shaft of the tibia that were treated from 1975 to 1980 with immediate intramedullary Lottes-nail fixation and with débridement and irrigation, with minimum periosteal disruption, all but one healed. The rate of infection was 6 per cent; of delayed union, 16 per cent; and of malunion, 4 per cent. One fracture, with arterial injury, resulted in amputation. The wounds were classified as Gustilo and Anderson Type I (24 per cent), II (12 per cent), or III (64 per cent). Seventy-six per cent of the patients had other fractures, and 38 per cent had a fracture of the ipsilateral femur. Sixty-four per cent of the fractures were segmental and 36 per cent were transverse with comminution.

Fractures of the tibia treated with Lottes nail fixation.

We have reviewed 60 consecutive cases, occurring in 57 patients, of intramedullary fixation of fractures of the midshaft of the tibia done over a ten-year period with the Lottes nail. Of 50 acute fractures, 38 were open fractures, nailed after adequate irrigation and debridement; the other 12 were closed fractures. The remaining ten cases were nonunions. All fractures healed with a rate of infection of 3.33% and a rate of malunion of 3.33%. Of the 50 patients with acute fracture, 29 had other fractures of long bones and 12 had ipsilateral fractures of the femur. The nailing facilitated their ambulation and care. All ten nonunions healed after nailing and bone grafting. Lottes nailing of tibial midshaft fractures is a simple procedure that gives stability, allows early weight-bearing with minimal shortening, and can be used in open fractures with minimal morbidity after adequate debridement.

Impingement exostoses of the talus and fibula secondary to an inversion sprain. A case report.

Impingement exostoses of the talus and fibula following an inversion sprain is an uncommon sequela to the initial injury. Although a high frequency of symptomatic tibial and talar impingement exostoses have been reported, changes on the lateral side of the ankle are more subtle with significant roentgenographic findings rarely seen. The authors present a rare case of impingement exostoses involving both the talus and fibula simultaneously. Arthroscopy visualized the tibiotalar and talomalleolar articulations. It revealed opposing exostoses of the talus and fibula, necessitating surgical resection. Arthroscopy is recommended for difficult diagnostic problems of the ankle and an awareness of the condition of post-traumatic impingement exostoses of the talus and fibula.
