The authors have operated on seventy instances of para-articular ectopic bone formation in fifty patients. Seventeen were paraplegic or tetraplegic, thirty were the result of trauma, two resulted from meningitis and one was a sequel of burns. The ectopic bone was located at the hip (thirty-three cases), the elbow (twenty-three cases), the knee (twelve cases) and the shoulder (two cases). The clinical, radiological and pathological features are reviewed. Several hypotheses on the mechanism of ectopic bone formation are put forward. The surgical procedures have included arthrolysis, arthrodesis, wide resection of the epiphysis, and total prostheses. There were ten recurrences. The authors conclude that the most extensive lesions occur in paraplegia and when the bone formation is situated at the hip.

In 50 black children with 70 slipped capital femoral epiphyses, a satisfactory result was obtained in 87% of the hips. Chondrolysis developed in 6% of the hips, occurring only when there was persistent intraarticular protrusion of the transepiphyseal fixation device. The chondrolytic process resulted in a relatively painless fibrous ankylosis of each hip. Avascular necrosis developed in 7% of the hips, and occurred only in the presence of a valgus reduction of an acute slipped epiphysis. Each case of avascular necrosis was of the whole-head type and was severely progressive. Biplane subtrochanteric femoral osteotomy was employed as a reconstructive procedure in the severely-displaced slipped epiphysis; it was delayed until after epiphyseal plate closure, and restored satisfactory hip function in all cases. Black children are not predisposed to poor results after slipped capital femoral epiphysis contrary to a commonly held impression.

The indications and techniques of an arthrodesis procedure, in children and adolescents, differ greatly with that of adults. And this, on account of, the growth of the epiphysis and its circulation during that period, and also, due to the thick cartilage coating the joint's surface. And therefore, only for the rare exceptions, where there are strict indications that the procedure is weeded, should it be performed, and preferably, when possible in late adolescence. It is advised to perform the arthrodesis even earlier, when it will prevent an increase in the static's impairement especially that of the feet. In general, for the seldom splintplastics one should consider autologous material, as primary choice. To conclude, special arthrodesis will be mentioned later.

Fracture-dislocation of the hip is an infrequent injury in adolescence. In combination with transepiphyseal separation of the capital femoral epiphysis, the injury is rare and catastrophic. A review of orthopaedic literature shows varied recommendations as to treatment approaches. The most recent articles have suggested that open reduction through a posterior approach and internal fixation is the best way to treat this problem initially. Later reconstructive measures are usually required because this injury often leads to avascular necrosis of the femoral head. The patient and family should be advised that the prognosis after such a fracture-dislocation is not good. Potential reconstructive measures after collapse of the femoral head include total hip arthroplasty and hip arthrodesis. Total hip arthroplasty is not a reliable means of providing a long-term painless joint in an active adolescent with one-joint disease. Hip arthrodesis has been shown to be a good alternative treatment for patients who develop avascular necrosis after this severe injury.

Limb lengthening by means of distraction through the callus of a knee arthrodesis was performed in a 14-year-old boy with congenital hypoplasia of one lower limb. Knee arthrodesis was indicated because of destruction of the distal femoral epiphysis caused by a previous bone lengthening procedure.

Seventy-five patients who had hemophilia were followed clinically and roentgenographically to assess the prevalence of hemarthrosis and the prevalence and severity of arthropathy of the ankle. The mean age of the patients at the time of follow-up was twenty-two years and seven months. The patients were divided into four age-groups: less than ten years (eleven patients), ten to nineteen years (twenty-one patients), twenty to thirty years (twenty-four patients), and more than thirty years (nineteen patients). Intra-articular bleeding occurred more frequently in the joints of the lower extremities than in the joints of the upper extremities. During the second decade of life, hemarthroses occurred more often in the ankle than in the knee. A history of recurrent bleeding into the ankle joint, chronic synovitis, and overgrowth of the medial portion of the distal tibial epiphysis was associated with an early onset of arthropathy. In older patients, compression arthrodesis of the ankle joint was helpful in eliminating pain, recurrent bleeding, and equinus deformity.

We evaluated the residual deformity and late treatment of thirty-four hips of thirty-one children who had had septic arthritis when they were less than one year old. The hips were classified into four groups on the basis of radiographic changes. Type-I deformity (five hips) involved transient ischemia of the epiphysis, with or without mild coxa magna, and these hips did not need reconstruction. Type-II deformity (eleven hips) included deformity of the epiphysis, physis, and metaphysis, and these hips needed an operation to prevent subluxation; the goals of the operation included improvement in acetabular coverage, improvement in abductor efficiency by epiphyseodesis or transfer of the greater trochanter, and equalization of limb-length discrepancy by epiphyseodesis of the contralateral limb. Type-III deformity (five hips) involved malalignment of the femoral neck, with extreme anteversion or retroversion or with a pseudarthrosis of the femoral neck that necessitated a realignment osteotomy of the proximal part of the femur or bone-grafting of the pseudarthrosis. Type-IV deformity (thirteen hips) included destruction of the femoral head and neck, with persistence of only a remnant of the medial base of the femoral neck. In the hips that had a Type-IV deformity, the complex clinical problems, which included severe limb-length discrepancy and incompetent articulation of the hip, necessitated operations such as Pemberton osteotomy, trochanteric arthroplasty, arthrodesis, epiphyseodesis of the contralateral limb, and lengthening of the ipsilateral tibia. The functional result was satisfactory in all five hips that had a Type-I deformity, in seven of eleven that had a Type-II deformity, in three of four that had a Type-III deformity, and in only four of thirteen that had a Type-IV deformity.

Many procedures have been described for treatment of unstable, deformed, or painful digital joints; most of these are various types of arthrodeses. These procedures have not been applied to children who have an open epiphysis for fear of damage to the growth plate. This study evaluates an arthrodesis technique that can be used for digital joint instability or deformity in skeletally immature patients. The diagnosis in most of the children in this series was related to non-traumatic congenital or developmental conditions. The joint most often fused was the thumb metacarpophalangeal joint. Results show a high rate of fusion with no interference in digital growth. Complications were minimal.

Two cases of acute chondrolysis of the upper femoral epiphysis associated with protrusio acetabuli are reported in two girls respectively 13 and 12 Y.O. The disease was unilateral in one patient and bilateral in other. Acute chondrolysis is characterized by onset of pain, restricted movements of the hip and evolution to an hip ankylosis within a few months. As usual no evidence of inflammatory disease could be shown at biology or at pathology of synovial membrane or of femoral head. CT and MR studies proved to be contributive in the first case. It's the author's opinion that in these 2 cases, chondrolysis appears as a complication of preexistent Protrusio Acetabuli.

Valgus deformity of the hindfoot can occur at the subtalar joint, the ankle joint, or at both sites. In children suffering from spina bifida, the ankle is often the main site of deformity. Thirty-five ankles with valgus deformity of the hindfoot were studied in 23 children with spina bifida. A radiological triad was observed in all patients: shortening of the fibula, lateral wedging of the distal tibial epiphysis, and lateral tilt of the talus at the ankle mortise . There was a definite correlation between the severity of wedging and the degree of talar tilt, and a fair correlation between the severity of wedging and the extent of fibular shortening. The results of operation in 12 feet are presented. It is concluded that any operations performed below the ankle on these patients (subtalar fusion or triple arthrodesis) is unlikely to succeed; the deformity needs to be corrected above the ankle (by epiphysiodesis or supramalleolar osteotomy). Radiological assessment of the ankle by taking weight-bearing films in the anteroposterior plane is essential to determine the true extent of the deformity before undertaking any operation.
