[Intertrochanteric osteotomy of the femur in children under 5 years of age. A new osteosynthesis plate].

Between 1980 and 1988, 70 varus inducing and varus derotation osteotomies of the upper end of femur were carried out in children. The osteotomies were maintained by a plate and screws developed by the author. This plate combines a bend to medialize the inferior fragment and screw perforations for easy positioning; it facilitates the procedure since the degree of varus correction depends completely on the shape of the plate. This firmly maintains the desired correction and reduces the amount of radiation received at subsequent controls.

[Role of acetabuloplasty in the treatment of residual cotyloid dysplasia before 4 years of age. Apropos of 14 cases followed over 5 years].

Concerning 14 cases with a follow-up of over 5 years, the authors describe their acetabuloplasty technique which is applied to dysplastic sockets with normal cotyloid cavity anteversion, innominate osteotomy is reserved for cases in which this anteversion is excessive; results have been excellent for 11 cases with adequate lowering of the roof-edge of the cavity and improvement of the C and CE angles as well as satisfactory subsequent bone growth; the result was insufficient in 3 cases in which either the head of the femur was off-centre or deformed by osteochondritis. The age of the patients was between 16 and 37 months. No growth disorder caused by the operation has been observed. Three failures may be related to pre-existing abnormalities in the growing areas of the acetabulum or to ischaemic troubles in the femoral head.

[The treatment of old dislocations of the radial head in children by osteotomy of the upper end of the ulna. Apropos of 15 cases].

Fifteen old dislocations of the radial head in children were treated by open reduction combined with a high osteotomy of the ulna and a reconstruction of the annular ligament. This method, described by the authors in 1978, was used in nine post-traumatic, three congenital, two paralytic and one dislocation associated with multiple exostoses. Twelve children were reviewed with a follow-up of two to 11 years. Nine radial heads remained stable and well reduced. The three congenital dislocations recurred. Eight elbows showed normal alignment and the other four were only improved. Ten elbows had normal movement or better movement than before the operation. Eleven children used their elbow normally or better than before. In all, 14 children were improved, and only one elbow had unaltered function. The results obtained in congenital dislocations should be able to be improved by a number of technical precautions.

[Surgical treatment of congenital dislocation of the hip in older children; analysis of the results. Apropos of 46 cases].

The results of surgical treatment of 46 congenital dislocations of the hip in children older than 4 years are analysed. Several techniques were used; progressive traction for a short time, stabilisation by plaster cast immobilisation or surgical reduction, pelvic osteotomy with or without combined femoral rotation osteotomy with shortening. Apart from other means of assessment, 3 radiological signs were used to determine the results - sphericity of the femoral head, coverage of the femoral head and centering of the femoral head. A new classification is proposed by the authors. Only 25 p. 100 of the results were excellent or good. The other hips had at least one radiological anomaly and 17.5 p. 100 of the hips had a non-spherical head. Cases with poor coverage of the femoral head did well when this was the only defect because this anomaly was easily corrected. In contrast, excentration of the femoral head was poorly tolerated in the long term. The degree and direction of excentration had to be assessed in the frontal plane.

Excision of hemivertebrae in children with congenital scoliosis.

This study reports the authors' experience with excision of hemivertebrae in the treatment of congenital scoliosis. Although it is limited to 10 cases, it is significant because of the 9 years follow-up. The first patients treated have already passed the age of puberty and this is the most interesting aspect of the study.

[Disk calcifications in children. Apropos of 17 cases].

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.

[Femoral neck fractures in children. About 14 cases (author's transl)].

The authors study 14 femoral neck fractures in children after a four and half years follow up. They point out the scarcity of these fractures in children. They describe their therapeutic methods and results. They corroborate the bad prognosis of this injury (femoral neck necrosis or further growth trouble) and emphasise the importance of a long term follow up to appreciate precisely the sequellar growth trouble. They discuss the responsibility of the femoral neck's vascularisation pattern in the origin of the sequella. They ask two questions : -- Is it useful to treat these fractures in emergency? -- Is the surgical dogma still valid?

[Humerus varus (author's transl)].

Humerus varus is a rare disease and has led to many controversies concerning its classification, its physiopathology, its treatment and even the measurement of the varus angle of the huméral head. This study is based on four personal cases and a review of the literature since 1900 about fifty cases. The relation between humerus varus, congenital aplasia of the glenoïdal articular surface of the scapula, and congenital dislocation of the shoulder, sometimes referred as shoulder dysplasia, is discussed. Two entities must be distinguished: The "true" humerus varus where the epiphyseal plate is in a varus position with a shortened arm. The deformities of the humeral head in varus without main alteration of the epiphyseal plate orientation. When there is a restricted function, especially in abduction, a valgization osteotomy of the proximal part of the humerus can be proposed (one case). The authors have no experience in lengthening of the humerus.
