[Surgical treatment of ruptures of the Achilles tendon. Apropos of 42 cases treated by Bosworth's technique].
There is no consensus on the treatment of acute ruptures of the Achilles tendon. We have chosen surgical technique with early muscle stimulation. This study analyses possibilities of functional recovery and complications in Athletes. ⋯ A rigid and stable reconstruction, allowing early weightbearing without equinus position seems to be a rational treatment for Achilles tendon rupture in athletes.

Case Reports[Scaphoid and lunate palmar divergent dislocation. Apropos of a case].
A case of palmar dislocation of the scaphoid and lunate which where dissociated from each other is reported with a 3.5 years follow up. A 32 years old man fell while reading his motorcycle. He landed on his left hand dorsiflexed. There was no skin dilaceration and neuro-vascular status of his hand was intact. X-rays showed a palmar dislocation of the scaphoid and lunate with a large gap between the two bones. The lunate was also completely dissociated from the triquetrum and the capitate. Distal pole of the scaphoid remained in contact with the trapezium. The patient was taken to the operating room, and after unsuccessful closed reduction, an open reduction through a palmar approach was performed. A complete disruption of the anterior capsule was founded and all perilunate ligaments were completely disrupted. Reduction was easy under direct vision, and the anterior capsule was repaired. A non displaced trapezium fracture seen at surgery was fixed with a Kirschner wire. A long arm cast applied for 6 weeks. At 3.5 years follow-up, the patient had an almost full range of motion and no residual pain. Power grip was 25 per cent reduced in comparison with the opposite side. X-rays showed a palmarflexed scaphoid and Magnetic Resonance imaging showed no evidence of avascular necrosis. ⋯ In such a case, and with a low rate of avascular necrosis in perilunate dislocations treated early we suggest an open reduction and internal fixation (O.R.I.F.) to prevent carpal instability. We recommend combined volar and dorsal approaches for repairing anterior and posterior ligaments (especially interosseous ligaments on both sides of the lunate), associated with a stabilization of the entire carpum by scapho-lunate, triquetro-lunate, and capito-lunate Kirschner wire fixation.

Comparative Study[Biomechanical comparative study of three types of osteosynthesis in the treatment of supra and intercondylar fractures of the humerus in adults].
Supra and intercondylar fractures are the most common fractures of the distal end of the humerus in adult. An osteosynthesis consisting of a plate is the treatment of choice. But location and type of plate always remain open for debate. The authors present the results of an in vitro biomechanical study, which compared the stiffness of three types of osteosynthesis commonly used in these fractures. ⋯ In spite of the progress of the material and the accuracy of the indications, the treatment of supra and intercondylar fractures of the distal end of the humerus is always a difficult problem. The devices have to be as stable as possible to allow an early motion. The best one should be placed on both sides of the distal humerus, because of the sagittal cyclic forces it undergoes, but this location is anatomically impossible. Our study concludes that the device using the Lambda plate i

All intramedullary femoral surgery entails embolic phenomena which explain peroperative collapses formally known as bone cement implantation syndrome, as well as perioperative fat embolism syndromes. Locally, the bigger the cavity is, the higher the number of accidents: 2.5-5 per cent for GUEPAR hinged-knee prosthesis, 1.75 per cent for total hip arthroplasty with long stem, and 0.1 per cent during classic THA with cement limited to the metaphysis. Anomalies in bone vascularization also increase risk: 10.5-13 per cent during prophylactic nailing for shaft metastases, 1-11.5 per cent during hemiarthroplasty cemented in osteoporotic bone of femoral neck fractures, and only 0.1 per cent during THA implanted because of arthrosis. ⋯ Preventive treatment is surgical as there is an inverse relation between embolic marrow and marrow eliminated by large volume washes (which is often more effective than draining). Cement indications in older patients as well as the choice of fixation techniques in femoral fractures must take into account the cardio-pulmonary condition of the patient. Resuscitation procedures dealing with these complications end in the patient's death in half of the cases.

[Value of orthopedic treatment of distal fractures of the forearm in children. Apropos of 152 cases].
Distal forearm fractures in children are frequent. Management is conservative except in rare cases which will be discussed. ⋯ Close reduction is possible for fractures with large displacement but must be done perfectly and the cast must be adapted. If instability, irreducibility and/or incorrect reduction exist, management must include posterolateral and intrafocal percutaneous pinning, especially in older children. While rare, this indication must be known.
