The authors have studied a case of familial osteopoikilosis. This rare radiological finding was observed in four of eight studied cases. The progressive character of the disease during the puberty was noticed.

After a brief description of the classification of fractures of lower and of humerus in children, methods are described for the application of different orthopedic and surgical procedures developed over the years. Treatment of supracondylar fractures remains very conventional (Judet's method), experience lacking in the use of contention in strong flexion for these fractures. Emphasis is placed on two points: the need for perfect reduction under all circumstances, since growth will have little impact on correction of residual faults, and the quality and reading of review radiographic images to avoid major mistakes in reduction.

In order to illustrate the phenomena which occur at the first contact between arterial prostheses and blood, an in vitro test is suggested which may be used to quantify the retention of the cruoric matrix using labelled compounds and confirming the nature by scan electron microscopy. Reorganisation of the cruoric matrix is dependent upon the scarring of polyesters which retain considerably more blood substances than microporous polytetrafluoroethylenes or the biological models dealt with, the course of which after implantation is closer to passivation.

Since May 1982, when the pediatric surgery group of Rouen has published their study in the 39th congress of "Societe Française de Chirurgie Infantile", regular surgical attitude in treatment of intussusception was abandoned by our team. Seventy cases were admitted in our section in the period (06-82/06-86), age ranged from one month to nine years. All except one were subjected to radio-opaque enema as a method of treatment with success rate of 89% reduction. Optimum conditions, failures (7 case), perforation (one case) and recurrence are presented. We conclude the efficacy of this treatment in condition of a rigorous technic.

This study is based on 48 cases of paralysis of the femoral or sciatic nerves complicating hip surgery, mostly total hip arthroplasty. Most of these lesions arose during difficult operations. The diagnosis was clinical and electromyographic, but it was not always made from the outset. The prognosis was better for the cases of paralysis of the femoral or peroneal nerves than for the cases of generalised sciatic paralysis in which the recovery, slower as it was, was only satisfactory in 15 cases out of 26. The treatment was primarily medical and required reeducation. A surgical treatment was considered when the electrical exploration showed no improvement after 6 weeks.

Anatomopathologic study of fractures of lower end of femur in 87 patients demonstrated the frequency of compound lesions in adults, epiphyseal detachment being the most common finding in children. Therapy used resulted in consolidation within a mean period of 4 months. Anatomic results were satisfactory in 87% of cases, 2 of 3 patients recuperating a knee compatible with a normal active life. Complications were rare. The current therapeutic attitude in adults is resolutely surgical, particularly in case of an intra-articular fracture line. In children, treatment remains orthopedic, except for epiphyseal detachments when minimal fixation allows perfect anatomic reduction and avoids secondary growth disorders.

Three cases of Kirner's deformity in siblings are reported. Kirner's deformity consists in a palmar bending of the terminal phalanx of the 5th finger. The deformity is usually bilateral; the condition is congenital but the deformity is recognized in later childhood and has to be classified as osteochondrodysplasia.

A literature review allowed classification of seven cases of Sprengel's deformity based on that described by Rigault et al. This classification into three types as a function of degree of elevation defines each case within the context of associated malformations, and appropriate therapy. Surgery is indicated, employing Woodward's type of operation, for patients with functional and esthetic deficits, particularly in Rigault's type II deformity.

The radiographic results of treatment of unstable thoracolumbar spinal injuries by Harrington rods are reviewed. The loss of initial correction of kyphosis is 8 degrees on average. Correlation between good anatomical reduction and lapse of time before operation, level of instrumentation and solid spinal fusion exists. But, in burst fracture with deficient anterior pilar, the incidence of loss of reduction is important. The influence of Harrington rods on the spine is significant.

Jacquez constructed a properly posed, more general model for the Reed-Frost epidemic process by assuming independent behaviors for the susceptibles and introducing the generating function for the number of contacts per person. An alternative approach is proposed here that relies on similar hypotheses for the infectives and allows the usual chain-binomial structure of the infection process to be extended. For this new model, the derivation of the final size and the threshold phenomenon becomes much simpler. A detailed analysis and its generalization to heterogeneous populations and continuous-time models will be the subject of a forthcoming paper.

Latarjet's operations as single therapy was performed in 52 patients admitted since 1976 with recurrent antero-internal dislocation of shoulder. There were no recurrences but three patients (6%) complained of residual instability. Effectiveness of results depends on use of a perfect technique : the bony ridge playing both an active and passive role should be level with the antero-internal border of the glenoid.

In this report concerned with luxation of the elbow and fractures of the upper end of two forearm bones in children emphasis is placed on the importance of the initial treatment, since sequelae are not corrected during growth. Correct therapy requires firstly a precise diagnosis, this depending on the obtaining of images of very good quality, if necessary taken during sleep if the child has to be anesthetized. Therapy should be as atraumatic as possible, particularly in the region of the head of radius, to avoid its subsequent necrosis.

Lumbar surgery is currently benefiting from the development of anterior approach to the spine and the possibilities of body reconstruction by plate and bony graft. The anterior extraperitoneal approach enables access to the spine. The Fraser approach expose the lumbar and the lumbo sacral spine.

The authors report 2 cases of infantile digital fibromatosis. These benign tumours occur in newborns and infants, involving mainly the extremities (fingers, toes). Its prevalence is probably higher than the reported cases. The pathogenesis and treatment are discussed. The diagnosis of such fibrous tumours is useful since surgical treatment can be avoided in a majority of cases.

A simple, reproducible and reliable method is proposed for measurement of cotyloid version. Using a standing frontal image of hip, the cotyloid borders are identified and a single-plane geometric projection determines the precise degree of version. This study can also be made from a conventional frontal pelvic image with bipodalic weight bearing. Knowledge of spatial orientation allows a better approach to head-cotyle biomechanical phenomena and thus improved understanding of the genesis of certain hip diseases.

Results of three therapeutic modalities used for the treatment of a homogeneous series of patients with a Pouteau Colles fracture are analyzed. Orthopedic treatment provided deceiving results. Pinning was, on the contrary, very effective, intrafocal pinning with immediate mobilization of the wrist appearing perfectly effective. Few complications were reported in contrast to plastered immobilizations. Good results were obtained in 80% of cases and functional recovery was rapid, indicating that this method represents undoubted progress when compared with conventional therapies.
