The treatment of idiopathic scoliosis in adolescents: rotation or in situ bending?

Rotation alone is not fully efficient in order to correct all types of scoliotic curvatures. We report a series of 30 cases instrumented with the EUROS spine system and analyse reductions obtained with in situ rotation or bending alone or with combined maneuvres. The average age of surgery is 17 years for this series composed of 24 female and 6 male patients. The average follow-up is 2.3 years. The curve patterns are displayed with 6 major thoracic, 5 genuine double major, 4 double major thoracic predominant, 6 double major lumbar predominant and 9 double thoracic curves. Combination of both reduction techniques is advisable and is to be made according to the type of curvature and its reducibility in situ bending is made easier with this system without lockers and by reduced diameter of the rod.

[Sequelae of osteoarthritis of the hip in growing children. Apropos of 72 cases].

The authors reviewed a series of 72 hips in 60 children with sequelae of septic arthritis of the hip to evaluate the long term evolution. The average follow up was 7 years 8 months (Range 1Y-17Y). 40 hips were operated and 32 were not. The results were analysed according to clinical and radiological criterions in an attempt to propose a guide for treatment. Sequelae might also occur after both initial treatment with open drainage or aspiration. The study of sequelae according to the factors of severity (organism, age when infected) showed that the evolution of these cases of arthritis cannot be forecast. The authors noticed that very severe roentgenographic lesions could be well tolerated clinically, at least on a medium term basis. They advise great care before operating on dislocated hips when they are clinically well tolerated. Finally the authors insist on 2 little known lesions: caput valgum and caput antetorsum.

[Acute osteomyelitis of the ilium. A study of 2 cases with review of the literature].

The authors have made a review of the literature about two cases of osteomyelitis of the iliac ala. They insist on rarity of the disease and how often the right diagnosis may be delayed because of misleading clinical symptoms. Any tumefaction of the buttock associated with pelvic pain and with an infectious syndrome necessarily evoke an iliac osteomyelitis. The bone scan may be negative which need not exclude the possibility. The evolution may be the formation of intra or extra or sometimes simultaneous sub-periosteal abscesses which must be drained. This is the reason why the authors advise to verify systematically the other side of the ilium by its surgical trepanning in case of a sub-periosteal abscess.

[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.

Is the Cotrel-Dubousset really universal in the surgical treatment of idiopathic scoliosis?

We reviewed the results of 22 cases of Cotrel-Dubousset (C-D) instrumentation, 16 cases of anterior approach, and 200 cases of posterior approach by Harrington instrumentation and modifications of Harrington procedure. Posterior spinal fusion and instrumentation by C-D gives better correction and stabilization in thoracic and balanced double major curves. We no longer use the Harrington procedure and its modification. In lumbar and short thoracolumbar curves, VDS is still preferred. In some double major curves combined procedures, VDS and C-D are used to obtain more correction with a shorter fusion area.

New procedure to remove a centrally located bone bar.

A centrally located bone bar of the lower tibia was removed after epiphyseolysis with an Ilizarov device. The bone bridge attached to the metaphysis was easy to remove, and methylmethacrylate was used as an interpositional material. Varus deformity was corrected at the level of the epiphyseolysis. At the 2-year follow-up, there was evidence of further growth and correction of the varus was maintained.
