One stage femoral lengthening.

Femoral lengthening can be obtained by a technique using a Z osteotomy and a distraction device separate from the operative field. The expected gain in length is 3-3.5 cm in children, 4-4.5 cm in adults. Sustained flexion of the knee during the procedure prevents vascular and nervous complications. One peroneal nerve and 2 femoral nerve palsies were nevertheless observed in 180 cases of the whole series. These were caused by a failure to comply with technical details. Bony union occurs promptly in young children. Pseudarthrosis occurred 11 times in patients more than 16-years-old, and once in an 8-year-old child. Avascular necrosis of the bone fragments after total separation of the soft tissue from the femoral shaft explains the frequency of non-union after the age of skeletal maturity. Faster and sound union in adolescents and adults is obtainable by the use of decortication to exposure the femur and strong internal fixation. The best indication for this method is a moderate discrepancy allowing a safe and complete equalization of limb length.

[Degenerative spondylolisthesis. Clinical manifestations and treatment apropos of 26 operated cases].

The authors report 26 cases of surgically treated degenerative spondylolisthesis. Twelve patients complained of permanent uni or bilateral sciatica. All the others had a syndrome of intermittent claudication with pain and paresthaesia. The authors stress once again the highly evocative nature of this syndrome which reflects involvement of the nerve roots in the stenosed lumbar canal. Treatment consisted of lamino-arthrectomy which resulted in the disappearance of symptoms in most of cases. In four cases, vertebral slipping worsened during the post-operative cowise with, in three cases a recurrence of symptoms necessitating a complementary arthrodesis. This risk of increased slipping is a result of the instability created by the arthrectomy, especially when it is bilateral, and has led the authors to widen their indications for routine complementary postero-lateral arthrodesis.

[Dorsal tenosynovectomy of the wrist in rheumatoid arthritis. Results obtained in 30 cases].

With reference to a series of thirty synovectomies of the wrist in patients with rheumatoid arthritis, the authors report the results observed after an average interval of three years and six months. There was a remarkable reduction in pain in three-quarters of the cases. On the other hand, loss of mobility was noted in 15 patients. Resection of the cubital head was carried out in half of the cases. This was followed in two cases by internal translocation of the carpus, and in three cases by internal translocation combined with cubital inclination of the hand. The results of the tenddon repairs carried out in six patients have been completely satisfactory. A study of the present cases and of data from the literature confirms the local prophylactic value of tenosynovectomy which may also prevent tendon ruptures. The best result are seen in the less evolutive forms in which the risk of relapse is least, and in cases in which surgery is carried out on stable wrists with cartilage showing little alteration. In the presence of inferior radiocubital arthritis the resection must be systematic as it makes it possible to carry out a complete synovectomy of this joint. The authors compare the value of surgical synovectomy of the wrist with that of radioactive synoviorthesis.
