[Scoliosis].

Recent advances in the knowledge of the spontaneous course, pathogenesis and therapy of scoliosis are reported. In adolescent scoliosis, which is the most common form, the necessity for improving systematic detection is emphasized. Diagnostic procedures and currently accepted pathogenetic hypotheses are recalled. Therapeutic indications, which are closely dependent on the severity and the prognosis of each case, are outlined. Physical therapy is often unduly prescribed in patients with non-progressive curves, leading to useless expense. Concerning congenital scoliosis, it is pointed out that progressive scoliosis does not develop in all vertebral malformations. Conversely, progressive scoliosis secondary to vertebral malformations is often severe and may require a surgical procedure in early life. In neurologic scoliosis, preventive steps should be taken as soon as the underlying neurologic disease is diagnosed; therapy should be initiated when the angle is still small. In infants, scoliosis follows a spontaneously regressive course in 92% of cases.

[Prognosis of extensive vertebral arthrodesis for scoliosis using Harrington's rods. Initial evaluation].

The authors have studied the technical results and the social status of patients operated on for scoliosis with Harrington rods. Only 137 of the first 330 patients, now adults, could be located and questioned. The scoliosis was idiopathic in nearly all cases. Correction of angulation was comparable to that found in the international literature. The aesthetic results were fair. Most of the patients are still young, and lead active lives without any noticeable loss of function or discomfort, except for low back pain whose frequency is discussed. Scoliosis, therefore, is thought to influence the social and professional future of these patients very little. Their problems have been analysed by the use of a questionnaire. The follow-up period for this early assessment is still short and needs to be completed by a further review in 10 to 15 years. It is likely that these results will not then be applicable to scoliosis of the future whose management will be likely to have altered.

Osteoarticular abnormalities and orthopedic complications in children with chromosomal aberrations.

Chromosome abnormalities may result in a great number of osteo-articular anomalies. Little documentation concerning these anomalies is available. The main orthopedic problems encountered in 67 children with chromosomal abnormalities are reported here. Patients should be evaluated at regular intervals in order to detect osteoarticular involvement. Gradual deterioration results in disabling conditions which are difficult to manage. Orthopedic management should be mainly preventive. It's purpose is to delay or to avoid the onset of disabling complications.

[Limited osteochondritis complicating coxa valga in children (author's transl)].

Height cases of limited "osteochondritis" were observed in children showing some degree of coxa valga. The radiological appearances were different from those of Perthe's disease and resembled those of osteochondritis dissecans of the knee but with stability during their development. These "osteochondritis" were often bilateral; all the patients were male. In four cases some degree of platyspindyly was seen. It is thought that these hips are earlier and limited varieties of osteo-chondrodysplasia. The indications for varus osteotomy are discussed.

[Transient synovitis of the hip in childhood. "observation hip" (author's transl)].

Thirty-eight children suffering of a transient synovitis of the hip joint have been reviewed with a follow up of 2 to 20 years (mean 7 years). It appears that this affection is not as benign as it seems, for in 1/3 of the cases it remains clinical and roentgenographic sequelae some of them looking like a minor degree of Legg Perthes' disease. The authors insist on the treatment, with traction in bed, and on the necessity of a new roentgenogram 45 days after the onset of the illness, to exclude the risk of an osteochondritis of the hip joint. Nuclide bone scan cannot affirm the diagnosis of transient synovitis, but can only eliminate an osteochondritis of the hip when it shows hyperfixation of the hip.

[Progressive tibial lengthening in children (author's transl)].

The authors have studied 38 "simple" tibial lengthenings and 10 "iterative" tibial lengthenings in children, with the use of an external rigid distractor. Four out of five of these lengthenings have been performed in cases of constitutional shortness. The authors got an average lengthening of 4,2 cm (that is 17,5 p. 100) for first procedure and 5,5 cm (16,5 p 100) for iterative ones. Consolidation has been obtained after about 3 months and free walking was authorized after 6 months for simple lenghtenings. These delays are longer (5 months and 6 and a half months) for iterative lengthenings. The bone and articular complications observed are closely linked to the technic used. The authors recommended the use of an external distractor of Wagner type, an oblique osteotomy with ample oblique section and extensive tenotomies and aponevrotomies. Out of the author's own experience, the most frequent complications were: delay in consolidations, especially in acquired shortness, and foot complications, especially frequent on those patients with previous alterations at that level. Progressive tibial lengthenings must be, of course, part of a complete program of length equalization of the inferior limbs and must however be preceded by the necessary surgery to obtain rightness and stabilisation of the knee, leg, ankle and foot before starting the required lengthening.

[Surgical treatment of dorso lumbar scoliosis in a homocystinuric child (author's transl)].

The authors report an observation which is interesting in many points of view. 1. A homocystinuria was found in a 7 year old child. The diagnosis of this disease in the sister of the patient led to make a family schedule and permitted to connect to this homocystinuria the entirety of the pathological signs found in the patient, particularly a serious scoliosis. 2. Because of the rarity, the severity of the vital prognosis and the risk of thrombo-embolic complications of the homocystinuria any important surgical intervention was given up until the age of 13 years, but the aggravation of the scoliosis at this moment made an operation necessary. After an orthopaedic, dietetic and anti-aggregative preparation, a posterior vertebral arthrodesis was done without any incidence. 3. One year after this intervention, the orthopaedic as well as the medical evolution have been favourable, and there have been no accident to deplore, especially no thrombo-embolism.

[Instability and kyphosis following cervical laminectomy and occipital craniectomy in children (author's transl)].

The authors analyse the various factors of spinal instability and their respective importance in a series of 113 patients in which, either the occipital cerebellar pits or the cervical spine had been approached surgically. The essential cause was mechanical failure consecutive and related to the number of levels of laminectomies performed, even when the articular processes and their capsule were left intact. While craniectomy and ablation of the posterior arch of the Atlas was rarely, if ever, responsible for instability, the frequency rises to 25% once the Axis, the spinous processes and laminae have been removed. Instability was present in 80% of the cases in which three or more levels are involved. Moreover, cervical laminectomy was nearly always followed by instability, above all when the cervico-dorsal transitional zone was involved and even when only a small number of vertebral levels had been operated on. Location of the instability was always at the limit between the lowest level of laminectomy and the lover lying intact vertebra. Diagnosis has gone unrecognized until presently: the severity of the possible complications have led the authors to propose preventive surgical management. It this serie, an anterior vertebral bone graft was prefered. Consciousness of the risks involved should lead to better prevention, be it at the moment of neurosurgical surgery or in the follow-up period. However, preventive treatment creates several problems, which may only be solved by a currently undertaken prospective study.
