Fractures of the proximal tibial metaphysis in children: review of a series of 25 cases.

Twenty-five cases of fractures of the proximal tibial metaphysis in children are reported. They are divided into three groups: torus fractures, greenstick fractures, and complete fractures. Genu valgum appeared in 12 cases of complete or greenstick fractures. Eleven deformities deteriorated progressively in the year following trauma. Three of these were spontaneously compensated for by growth at the inferior epiphyseal plate. Four corrective osteotomies were performed in the series, but this procedure is not recommended because of the significant risk of recurrence and the possibility of compartment syndrome, even with associated fibular osteotomy. A persistent valgus deformity can be corrected during puberty, if necessary, by a medial tibial epiphysiodesis.

Osteoid osteoma or osteoblastoma of the cervical spine in relation to the vertebral artery.

Osteoid osteoma or osteoblastoma of the cervical spine require complex therapeutic solutions in cases in which there is proximity to the vertebral artery. We describe four such cases. Generally, resection was efficacious and without recurrence, but twice the vertebral artery had to be sacrificed. Although we did not find any serious neurological complication, we concluded that a simple sacrifice of one of the vertebral arteries is not acceptable, principally because of the importance and variability of the unknown radiculomedullary branches of the vertebral artery. We discuss the therapeutic strategies for treating these lesions, namely preoperative investigations, surgical approaches, and vascular control.

[The prediction of growth in long bones in poliomyelitis (author's transl)].

The authors have studied 15 cases of unilateral poliomyelitis and have compared the growth of the intact lower limb with that of the paralysed limb. It is concluded that no accurate prediction can be made except by multiple measurements. In most of the cases, growth was steady, the rate of shortening increasing by regular degrees. However, in very young children the degree of shortening was more consistent and was similar to that in congenital abnormalities.

Osteochondral fractures of the glenoid fossa of the ulna in children: review of four cases.

Osteochondral fractures of the glenoid fossa of the ulna are exceptional injuries in children. These lesions can present diagnostic problems because the fragments are often radiolucent. We followed four children for 3, 6, and 24 months and 12 years, respectively. The elbow was definitely dislocated in two, and was probably dislocated in two other, children. The most reliable paraclinical examination was conventional sagittal tomography. Open revision is mandatory for reduction of the fracture and, when performed early, may lead to excellent functional results.

[Birth palsy of the brachial plexus--surgical exploration and attempted repair in twenty one cases (author's transl)].

Twenty one cases of birth palsy of the brachial plexus have been explored surgically. The patients were aged from seven weeks to nine years. The results of pre-operative examination are described and myelography is considered to be especially important. It was found that ruptures of the upper roots at the junction of C5-C6 were frequent and could be repaired by nerve graft. Avulsion from the spinal cord was more frequent in the lower roots. It is concluded that surgical exploration and attempted repair should be done early, preferably at the age of two or three months in cases of absence of spontaneous recovery.

[Progressive bone lengthening using Wagner's technique (author's transl)].

The authors have reviewed the results of 30 surgical procedures of progressive bone lengthening using the Wagner's technique. In 28 cases, internal fixation was applied at the end of the lengthening period. There were 17 femora and 13 tibae operated on. In 6 cases, lengthening was associated with a correction of the alignment of the femur, and in 2 cases was associated with the treatment of a non-union of the tibia. Complications are described; they were found to be relatively rare.

[Oral pristinamycin therapy for bone and joint infections in children. A report of 50 cases (author's transl)].

50 children with bone and joint infections (acute osteomyelitis, suppurative acute arthritis, osteoarthritis) were treated with pristinamycin. The responsible bacterium was most often but not exclusively Staphylococcus aureus; its sensitivity to various antibiotics is discussed. The value of biochemical tests for diagnosis and follow-up is emphasized; the potency of this drug avoids the need for intravenous therapy. A therapeutic protocol according to age, type of and sensitivity of the germs is proposed.

[Epiphysiodesis in the treatment of discrepancies in length of the lower extremities (author's transl)].

Thirteen children treated only by epiphysiodesis for inequality in the length of lower limbs were reviewed after maturity. The intention was to estimate the value of the predictions of growth used in this work and the effectiveness of the operation. The result of this procedure depends upon the accuracy in predicting the further growth in order to determine at what age the operation should be performed. The imperfect results of epiphysiodesis are attributable to prediction errors and to operation delay in some cases. Prediction can be made using only roentgenographic measurement of the femur and the tibia, skeletal age and growth charts of Green and Anderson. It is not necessary to make use of others factors such as the size of the child.

[Neurologic complications of surgery of the spine in children].

Neurological deficiency can occur during or after spinal surgery. The most severe complications are seen after instrumental correction for scoliosis or kyphosis. Regression of paraplegia, paraparesia and Brown-Sequard syndrome is never a certainty and usually incomplete. Preoperative manoeuvres and evoked potentials do not provide absolute security and metal instrumentation should always be used prudently. The main risk factors are vertebral malformation, major kyphosis, preoperative signs of neurological deficit, excessive correction and double anterior and posterior access. Finally, the canal is poorly vascularized from T4 to T8 or T9 which can raise further problems. Cordal deficiency during or following almost always requires removal of the metal implant, and exploration of the canal possibly with MRI. Injury include direct contusion of the spinal cord, devascularization and compressive haematomas. The frequency of neurological complications is currently about 1% and only extreme prudence and knowledge of causes can reduce this rate.

Radiological study of severe proximal femoral focal deficiency.

Twenty-two hips in 20 children, all classified as Amstutz type 3 proximal femoral focal deficiency, were studied by means of plain radiographs, arthrograms (30), ultrasound examination (six), computed tomography (CT) scans (including five arthrographies with CT) and magnetic resonance imaging (MRI; nine). These investigations demonstrated that in 15 hips, the superior femoral epiphysis was mobile in the acetabulum, whereas in six others, it was fixed and fused to the acetabulum. In one case, it was impossible to prove whether the epiphysis was mobile or fixed. The key radiologic and other image features that allow these conclusions to be drawn are described. The therapeutic implications are important, as it would be pointless or harmful to attempt to consolidate the femoral neck or put it into valgus when the epiphysis is spontaneously fixed to the acetabulum.
