[Compartment syndrome of the leg (author's transl)].

The authors have observed ten compartment syndromes of the leg. Nine occurred after tibial fractures, one after a contusive trauma. Early signs those of muscular and neural ischemia, with an acute pain when the toes are passively mobilised. The cast must be promptly removed. In 6 cases the two compartments were involved. In all cases the pulses were palpable. Arteriographs could occasionaly verify the integrity of the main arterial trunks. The treatment is based on early fasciotomies. It was realised in 5 cases, with good results when the fasciotomy was realised more than twelve hours after the trauma, the muscles were more or less necrotic. In one case all the muscles of the leg had to be excised.

[Infected total knee prostheses treated by Papineau's technique and arthrodesis (author's transl)].

The technique of arthrodesis of the knee after removal of an infected total prostheses is described. It was used in four cases. In the first stage, the prostheses and cement were removed, the wound was left open and knee immobilized by Hoffman external fixation. Details of the fixation are given. The second stage of filling of the wound by cancellous chips was performed two weeks later. On average, the fixation was removed after seven months. Some mechanical experiments were made to establish the best type of fixation device.

[Aseptic osteonecrosis in the renal transplant patient. Apropos of 27 surgically treated cases].

The authors have treated 27 cases of avascular necrosis of bone in patients following renal transplantation. They have noted some specific features--early onset after transplantation, multiple localization and rapid and severe progress of the lesion. The authors discuss the pathogenesis as it relates to cortico-steroids, bone dystrophy due to renal failure and the effects of dialysis. Surgical treatment requires special care because of the poor general condition of the patient. Operations have been done on 20 hips (12 forages, 1 cup arthroplasty, 2 Moore prostheses, 5 total prostheses) and 7 knees (1 forage, 6 removal of loose bodies). Two procedures were found to be valuable at the hip--forage at a very early stage and total prosthetic replacement. The indications for operation depend on the degree of functional disability. For the knee, necrosis affected both the femoral and tibial component resulting in effusion and locking. The only useful procedure seemed to be removal of loose bodies. In every case, surgical procedures must be conducted under careful and constant medical supervision.

[Fatigue fractures: apropos of 8 cases].

Eight cases of fatigue fracture were observed by the authors. In two patients, they presented in metatarsal bones; others were in the lower end of the tibia, in the shaft of the fibula, in the patella, at the upper end of the fibula, in the shaft to the tibia and in the neck of the femur. The main features of these fractues, which occurred in previously intact bones, are reviewed. The role of previous muscle imbalance, or metabolic disturbance, (by age or in pregnancy) is discussed. Good results were obtained by simple immobilization. Surgery may be indicated in the two situations: 1. To eliminate the possibility of a bone tumour by biopsy and, 2. For internal fixation in special sites such as the femoral neck to avoid coxa vara or when healing is very slow, as occurs particularly in the femoral shaft.

[Fractures of the odontoid process. 94 cases, 61 treated by arthrodesis].

The authors have reviewed 94 cases of fractures of the odontoid process, 21 of the with neurological signs. The conclusions were as follows: 1) Conservative treatment in 26 cases led to 9 non-unions; 2) 27 recent fractures were operated on (arthrodesis) with 24 fusions; 3) 54 cases were treated more than 30 days after the accident: 15 ot them demonstrated neurological involvement, 34 of them were operated on; 4) The surgical technique is fully described, usually the operation aimed at fusing C1 to C2; 5) One patient died, none was aggravated, all were somewhat improved on the neurological standpoint; 6) On a functional standpoint neck mobility was less decreased after conservative treatment than after cervical fusion.
