[Segmental posterior spinal osteosynthesis using the Luque-Dove technic].

The Hartshill frame is method for segmental osteosynthesis of the spine. It is attached at each vertebral level by sub-laminal metal wires. This frame therefore ensures immediate stability and avoids the need for a post-operative corset. It enables correction of frontal deformities (scoliosis) whilst retaining sagittal physiological curves (lumbar lordosis--dorsal kyphosis). It ensures the fixation of posterior spinal instability (destruction of posterior ligaments and bone tissue, spondylolisthesis, etc.). The Hartshill frame can thus be seen to be a posterior brace. It has been used in 92 patients, (53 lumbar disorders, 10 cases of scoliosis, 4 of kyphosis, 19 tumors, 6 fractures). Results are generally entirely satisfactory in the mid term apart from fractures (recurrence of initial displacement). Specific complications are of a neurological nature (cases of cutaneous hyperesthesia, one severe motor deficit) long-term problems with device and material are uncommon; rupture of sub-laminar wire 8 cases; secondary incurving of frame 1 case.

[The shelf operation for painful hip dysplasia in adults. Apropos of a continuous series of 230 cases].

230 shelf operations were carried out between 1961 and 1985 for painful acetabular dysplasia or subluxation of the hip. 208 patients have been followed up for more than one year, with 79 for between 10 and 24 years. Substantial relief of pain was obtained in 88%. The benefits of operation usually continue for many years. Factors which may lead to a poor result are advanced age, dislocation of the hip and the presence of marked osteoarthritic changes. The results have been compared with those obtained for Chiari's osteotomy, and the relative indications for the two procedures are discussed.

Acetabulum↗

[A simple method for measuring anteversion of the acetabulum from a frontal radiograph of the hip].

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.

[Congenital elevation of the scapula].

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.

[Subperiosteal (juxtacortical) chondroma of the hand. Apropos of 4 cases].

The subperiosteal type of chondroma of hand is reputedly rare. Four such cases are reported two in adolescents, one in a child and one in an adult. The chondroma being localized to the phalanges, its most frequent development site. In one patient multiple chondromata were present. The relevant literature and typical characters of these subperiosteal chondromata are reviewed. Radiological images show clearly outlined tumors due to peripheral calcification. Treatment is surgical by block excision through healthy bone, this avoiding recurrence.

[Extraperitoneal approach to the lumbar spine and lumbosacral region].

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.

[Recent fractures of the distal end of the femur. Apropos of 87 cases (after the end of treatment)].

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.

[Our concepts of treating recent fractures of the lower end of the humerus in children].

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.

[Fractures of the upper end of radius and ulna and recent dislocations of the elbow in children].

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.

[Stabilization of thoraco-lumbar spinal fractures using Harrington's equipment. Study of the evolution of spinal curvatures].

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.

[Apropos of 87 dislocations of total hip prostheses].

Eighty seven dislocations were seen in 1571 consecutive total hip replacements, mostly performed through a posterior approach. Nine occurred immediately after operation and most of the remainder within 5 weeks. In 26 cases further dislocation occurred, and in 11 patients another operation was required. The 87 dislocated hips have been compared with the remaining 1484. Factors predisposing to dislocation included revision operations, the experience of the surgeon and proper reconstruction of the abductor musculature. When the hip was deemed unstable at the end of an operation, dislocation occurred on 18 occasions out of 20 such cases. The position of the components in the dislocated hips was compared with that in 100 stable prostheses chosen by random sampling. A vertical acetabular prosthesis, and retroversion of the acetabular and femoral components all favoured dislocation. In 331 replacements with a 22 mm diameter head 29 dislocations were seen (8.7%), whereas in 168 replacements with 32 mm heads, 5 dislocations occurred (2.9%).

[Transverse fracture of the 2nd sacral vertebra with neurological signs. Apropos of a case].

The authors report a case of transverse fracture of the second part of the sacrum with neurological signs. Whilst such a lesion would appear very rare, associated involvement of the sacral roots is very common. Recovery of the neurological deficit syndrome is hazardous. A review of the literature fails to provide the basis for a defined programme of management.
