Purpose of the Study: The aim of this study was to relate the efficacy of cutting the psoas tendon in case of high congenital hip dislocation treated by slow reduction according to Somerville-Petit., Material: Twenty psoas tenotomies were realised between 1982 and 1992. The average age was 11 months 15 days old, they were 15 girls and 5 boys. Among them, only 9 patients had never been treated., Method: By a short surgical approach close to the lateral lip of Scarpa's triangle, we cut the psoas tendon at the musculotendinous junction doing this suppresses the obstacle that interferes with the femoral head coming down., Results: Results have been evaluated on clinically and especially radiologically. All hips remain stable except one case. A graduated subluxation of the hip occured after removal of the plaster. 18 hips have been revised between the third and fifth year. Clinical results were excellent, on radiological controls 5 hips were considered flawless, 11 satisfying, and 2 were imperfect. Only 2 children have been seen ten years later with excellent clinical and radiological results., Discussion: The hypertrophic psoas tendon interposes between the femoral head and the acetabulum creasing the capsule and the limbus. Cutting tendon of the psoas will decrease the numerous unexplained failures that occured during slow reduction according to Sommerville-Petit method. The use of these surgical techniques may make more outstanding the tenotomies time., Conclusion: Tenotomy of the psoas tendon realized by a short surgical approach without any articular effraction, allowed us to obtain complete reduction of the hips dislocation in these 20 patients.

Introduction: The purpose of this study is to compare the results of direct reinsertion of the distal bicipital tendon to the bicipital tuberosity, with other methods described in the literature., Material and Method: This study is based on six athletic patients, all male, ranging in age from 42 to 62 years old. The rupture of the biceps occurred during an unusually violent effort in flexion and forced supination of the arm at a 90 degree of flexion. The surgical procedure which took place between a week and a month after the accident, consisted in a direct reattachment of the detached tendon., Results: No paralysis in the area of the radial nerve occurred. All patients regained normal range of motion of the joints with maintained strength., Discussion: Faced with a recent lesion in a young patient, a reinsertion on the bicipital tuberosity is desirable in order to maximize the strength and movement of the biceps. This simple technique uses a single approach. It does not weaken the bicipital tuberosity nor the muscular function of the biceps.

The technique used by the authors for removal of hemivertebrae is fully described. Two approaches are made, one posterior and one lateral at the same surgical session. This allows satisfactory control of roots, medulla and radicular vessels. The indications are described with reference to the age of the patient, the level of the lesion and the type of anomaly. It is concluded that it is a valuable procedure in progressive severe congenital scoliosis. 7 cases are reported without any neurological complication.

Seventeen cases of calcification of the intervertebral discs in childhood have been seen. Only cervical lesions gave symptoms. In several cases the lesions were multifocal (cervical and thoracic) and there was a familial history in one case. Two cases were observed for 10 and 8 years respectively. It was noted that cervical calcifications tend to disappear while thoracic ones persist but are asymptomatic. The authors postulate that this is due to differences in the physiology of the nucleus and in the biomechanics at different levels of the spine. A high frequency of associated spinal deformities was noted. For this reason, the late prognosis must be guarded.
