[Clinical and radiological semiology of unilateral hip dysplasia in infants].

PURPOSE OF THE STUDY: The much discussed subject of hip dysplasia in infants already seems well and truly exhausted, yet the simple clinical examination and frontal pelvic X ray of Unilateral Hip Dysplasia in infant reveals a semiology which is both specific and easily made conspicuous. MATERIAL: This study is based on a prospective consecutive series of 50 cases of Hip Unilateral Dysplasia in infants. METHODS: The study particularly endeavoured to find: postural, muscular, articular, spinal or cranial asymmetries, fixed positions of the foetus in utero, systematic sleep positions, three plans asymmetries on frontal pelvic X-ray. RESULTS MAIN RESULTS: Unilateral Hip Dysplasia in infants was associated to a constant contralateral retraction of the abductors, to plagiocephalism and a fixed in utero position in almost half of the cases, to an asymmetrical sleep position in 3/4 of cases, and to pelvis asymmetry in 84 per cent of cases. DISCUSSION: The possible cause of Unilateral Hip Dysplasia in infants must be evocated at surgical consultation analyzing in utero positions or sleep positions. CONCLUSION: Treatment of dysplasia depends on how serious it is and on the asymmetries observed.

Computerised tomography in non-treated congenital hip dislocation.

Computerised tomography, carried out in 5 non-treated cases of congenital dislocation of the hip, shows that the femoral head can move in a large anteroposterior cavity. When the hip is extended the common position of dislocation is lateral superior and slightly anterior to the acetabulum. When the hip is flexed (at a right angle), the femoral head is located posterior and slightly superior to the acetabulum. Dislocation reduction has always been possible. When the hip is flexed a large "click" takes place; whereas if the hip is extended, the "click" is less noticeable, or even absent.

Elastic stable intramedullary nailing of femoral shaft fractures in children.

We report the use of elastic stable intramedullary nailing (ESIN) in 123 fractures of the femoral shaft in children. Flexible rods are introduced through the distal metaphyseal area, and the aim is to develop bridging callus. Early weight-bearing is possible and is recommended. There was one case of bone infection and no delayed union. Complications were minimal, the most common being minor skin ulceration caused by the ends of the rods. A surprising feature was the low incidence of growth changes, with a mean lengthening of only 1.2 mm after an average follow-up of 22 months. Compared with conservative treatment, ESIN obviates the need for prolonged bed rest and is thus particularly advantageous for treating children.

[Comparative study of the Armstrong and Harrington technics in the treatment of idiopathic scolioses].

Between 1982 and 1985, idiopathic scoliosis was treated by instrumentation using Armstrong's technique, segmental spinal instrumentation (Luque's method) being reserved for neuromuscular scoliosis. Of the 29 patients treated by the technique 22 have been followed up for more than 18 months. Results were compared with those in a similar group of 30 patients operated upon using Harrington's original procedure between 1977 and 1982. This retrospective study complements that of Michel et al., and provided the following results: Although the instrumental correction gain was comparable in the two groups after 2 years, the angular loss was less marked by 3.4 degrees in the Armstrong when compared with the Harrington group. In addition, this mounting offers stability of lumbar contra-curvatures of which there is a lack of deterioration. Horizontalization of the lower load-bearing vertebra was better in the Armstrong group and allowed the choice of a load-bearing vertebra above that of the Harrington's group in two-thirds of cases. The changes in vertebral rotation and gibbosity are supplementary advantages of Armstrong's technique. Postoperative contention is still necessary, whatever technique is used, but the use of a second branch placed in distraction in the convexity is recommended, to improve quality of surgical treatment of idiopathic scoliosis.

Elastic stable intramedullary pinning of long bone shaft fractures in children.

Stable intramedullary pinning is an excellent method for treating shaft fractures in children when there is an indication for operative management. It is a new biomechanical concept which aims at developing the bridging external callus. This closed pinning uses flexible rods which are introduced into a metaphysial area. Technique, results and indications are described particularly in regard to shaft fractures of the femur and the forearm. This closed surgical procedure can always be performed; complication rates are slight (no sepsis, no delayed union). Early mobilisation is possible, and use of a cast is unnecessary.

[Lengthening osteotomy of the femoral neck with transposition of the greater trochanter in acquired coxa vara].

The main problem in acquired coxa vara is related to shortening of the femoral neck and upward displacement of the greater trochanter. Using the Wagner technique, the authors have performed an intertrochanteric osteotomy in five adolescents with transfer of the greater trochanter to lengthen the femoral neck. The technique is described. The early results are encouraging.

[Osteoarthritis in infants. Follow-up and treatment].

For 25 years, 102 hematogenous septic arthritis have been observed in 82 newborns and infants. The hip joint was the most commun site of involvement (63 cases), than the knee (23 cases), the shoulder (7 cases), the elbow (5 cases), the ankle (3 cases) and one wrist. 14 times, two or more joints were involved. When the diagnosis was made early, an aspiration of pus and an irrigation of the joint was done. But in severe and delayed arthritis, an arthrotomy was preferred. In all cases, joints were immobilized in a post-operative cast or with a traction management, and parenteral antibiotics were prescribed. 52 sequellae were noted, two third of these were seen in second hand. Sequellae are detailed joint by joint, and the authors describe different stages from minor dysplasia and abnormal growth of the epiphysis to severe destruction of the bones and persistent dislocation. Treatment of sequellae is proposed: 1. The hip joint. Dysplasia and deformities of the head and/or the neck were corrected with femoral osteotomy. In 2 cases, a pelvic innominate osteotomy was performed. Progressive coxa vara with short neck and greater trochanteric overgrowth were treated with femoral neck lengthening (personal technic). Dislocations needed open reduction of the hip and extensive excision of the acetabular fibro-fatty tissue. In a few cases, a Colonna's procedure was made. In total destructions of the upper femoral extremity, the treatment consisted in trochanteroplasty. In partial epiphysiodesis of a femoral condyle, disepiphysiodesis was obtained with resection of the physeal bone bridge (2 cases) or with free free physeal transplantation with microvascular anastomosis (2 cases).(ABSTRACT TRUNCATED AT 250 WORDS)

[Congenital anterior dislocation of the hip].

An apparently congenital antero-superior hip dislocation is identified during surgery. With reference to this case, three possible clinical courses for congenital hip dislocations are outlined: As a rule full recovery is most frequent. However, a posterior dislocation which is persistent tends to become postero-superior upon weight-bearing. Anterior dislocations as well as antero-superior subluxation appear to be rather common. Both pathology and the CAT scan attest to this fact. Extension, which is a true dislocating position for a retracted hip in adduction anc rotated externally, is probably responsible for such an evolution. Anterior dislocation and especially antero-superior subluxation are frequent findings which can be explained anatomically. The eventual complications of the antero-superior wall of the acetabulum resulting from these, will be the objective of most of the usual treatments for residual hip dysplasia.

[Legg-Perthes-Calvé disease. Plea for an original ambulatory orthosis].

Legg-Perthes-Calvé disease is a local disease which should be treated by non-iatrogenic means. The authors have designed a new ambulatory orthosis allowing containment in abduction, flexion and medial rotation, with relief of weight-bearing on the femoral head. It was tested in thirty six hips. In only eight of them a surgical procedure had to be performed during the evolution of the disease (femoral or pelvic osteotomy) because of secondary exenteration of the hip.

[Closed flexible medullary nailing in pediatric traumatology].

Flexible Medullary Nailing is an excellent method in children when operative management is indicated. It is a new biomechanical concept using prebent flexible rods introduced in a metaphyseal area. In femoral shaft fractures, closed percutaneous nailing permits stabilization using wires inserted by a medial and a lateral approach. In severely displaced humeral fractures of the upper end, two Kirschner wires are inserted under X-ray control through a epicondyl hole. Pinning can be indicated in others fractures : tibia, radial neck (original procedure), fore arm, humeral supracondylar original procedure and shaft fractures. This closed surgical procedure can always be done; the complication rate is light (no sepsis, no delayed union). Early mobilisation is often possible and cast is not necessary.

[Interest of fistulography in the treatment of infection of arterial prostheses (author's transl)].

In groin distal anastomosis suppuration of an aorto or ilio-femoral prosthesis, preoperative opacification of the fistulous tract was used to assess the extent of infection along the prosthesis. In two patients, one with an ilio-femoral by-pass whose entire length was infected, and the other having an aorto-bifemoral by-pass with only one infected distal anastomosis, fistulography enabled us to plan the operative procedure consisting of venous by-pass and resection of the infected segment.

Elastic stable intramedullary nailing in forearm shaft fractures in children: 85 cases.

The results of elastic stable intramedullary nailing (ESIN) of 85 forearm fractures in children are reported. A single curved nail was inserted into each forearm bone with closed reduction. Immediate mobilization was allowed postoperatively. In a 3 year 6 month follow-up of 76 patients, 92% had excellent results with a full range of movement. There were neither nonunions nor infections. ESIN is recommended in the treatment of displaced forearm fractures in children older than 10 years of age, and in younger children when conservative treatment fails.

[Surgical treatment of fractures of the long bones in children. Interference between osteosynthesis and the physiological processes of consolidation. Therapeutic indications].

Flexible medullary nailing is an excellent method when operative treatment of fractures in children is indicated. It is a new biomechanical concept using prebent flexible rods introduced in the medullary canal through a metaphyseal area. This method can be used in all types of Femoral, Tibial, Humeral or fore arm fractures. In Each case, the operative technique is described. This closed surgical procedure has a low complication rate (no sepsis, no delayed union, no length discrepancy). Early mobilization is often possible and cast is not necessary.
