Trochanteric arthroplasty in the treatment of sequelae after septic arthritis of the hip in infancy.

The authors describe 17 patients submitted to trochanteric arthroplasty between 1979 and 1999 at the Division of Pediatric Orthopaedics and Traumatology of the Rizzoli Orthopaedic Institute. There were 9 females and 8 males aged from 1 to 8 years (mean of 4) affected with the sequelae of septic arthritis of the hip with complete destruction of the epiphysis and of the femoral neck (types IVB and V according to the Hunka classification system). Mean follow-up was 9 years (minimum 1, maximum 23). Surgery is described and indications are discussed: this is the only type of treatment that may be offered in place of conservative treatment.

Injection-induced contractures of the quadriceps during childhood.

A total of 8 cases affected with injection-induced contractures of the quadriceps occurring in 7 patients were followed-up at the Division of Pediatric Orthopaedics at the Rizzoli Orthopaedic Institute. Mean age was 8 years (minimum 5, maximum 9). Surgery involved arthromyolysis according to Judet whether or not associated with distal reconstruction of the quadriceps. Mean follow-up was 9 years (3-17). Mean increase in passive flexion of the knee was 70 degrees, while deficit in active extension was observed in 50% of cases. The clinical aspects indispensable for diagnosis, the therapeutic choices, the surgical method reported in the literature and the results obtained using this method are all discussed.

Focal myositis. Description of a case and review of the literature.

The authors describe a rare form of pseudotumor of the muscle tissue of an inflammatory nature with an unknown etiology that occurred in a boy aged 13 years, characterized by the occurrence of rapidly-developing swelling, no pain symptoms, with degeneration of the myofibers, evident eosinophilia and lymphomonoplasmacellular infiltrate. Surgical excision of the lesion is the treatment of choice.

Stiff-skin syndrome.

It is the purpose of this paper to present the case of a patient who came to our observation because of the occurrence of non-elastic hardening of the skin (stone hard skin) and of the subcutaneous tissue that began during early childhood. The parents reported having observed the gradual functional limitation of numerous joints with asymmetrical distribution, more evident in the elbow and the right scapulohumeral joint. There were no signs of involvement of the internal organs; hematologic testing was normal. Described for the first time in 1971 by Esterly nd McKusik and called stiff skin syndrome (SSS), this is a rare genetic alteration characterized by hardening of the skin and subcutaneous tissue associated with gradual joint stiffness and, at times, hirsutism. Generally, there are no modifications in the internal organs or in the musculoskeletal structures; anomalies of the immune system are not described. Modifications are manifested during early childhood causing gradual functional limitation of the hips and knees, with consequent difficulty related to posture and walking. Deficit in the upper limbs is less important. The literature describes about 25 cases with little incidence of familiarity; etiopathogenesis is unknown.

Pyle's disease. A description of two clinical cases and a review of the literature.

The authors present the case of a sister and a brother who came to our observation at different times and both affected with Pyle's disease with marked valgus of the knee. The clinical cases reported demonstrate how in Pyle's disease with significant valgus of the knee temporary asymmetrical tibial epiphysiodesis was able to correct the deformity, not only by provoking the momentary arrest of growth in the growth cartilage on the internal tibial aspect, but also by allowing for bone remodeling in the tibial metaphysis.

Lowe syndrome: general problems in a female patient.

The authors describe a clinical case of a patient affected with Lowe syndrome. Ocular modifications, as well as those involving the nervous system, renal function, and the locomotor apparatus, typical of the syndrome, are taken into consideration. The problem of axial deformity of the knee, secondary to spontaneous fracture of the femur, a frequent occurrence in these patients, is dealt with.

Lengthening of the lower limbs in Ollier's disease: problems related to surgery.

Ollier's disease is a chondromatosis of the long bones that occurs rarely but that is highly disabling because it causes severe dysmetria and deformity of the lower limbs. Surgical correction of these skeletal changes is obstructed by poor mechanical resistance of the bone tissue affected and by the amount of lengthening required to even the lower limbs. It is the purpose of this study to indicate the surgery of choice for the treatment of this disease, comparing the two most recent methods used: Wagner's technique and the Ilizarov method. The latter is more reliable in terms of mechanical hold and the possibility of correcting severe deformities, producing bone regenerate of excellent quality even in major lengthening procedures. These results were obtained by adapting the Ilizarov method to the features of the chondromatous bone, thanks to the extreme malleability of the circular external fixator.

The treatment of congenital hip dysplasia.

The authors take into consideration the different phases of the treatment of congenital hip dysplasia (CHD) as it is related to age and natural development. Within the first year of age three objectives must be aimed at: reduction of the epiphysis, its retention and immobilization, maturation of the hip. After three years of age, once the epiphysis has been reduced, reconstructive and stabilizing surgery must be performed (acetabuloplasty and femoral osteotomy) in order to correct the modified joint parameters. After ten years of age and until the end of growth the degree of dysplasia influences treatment, as intervention is justified (preferably with biological reconstruction of the acetabulum) in forms of severe dysplasia caused by the definite occurrence of pain at an early age. We emphasize the importance of adapting treatment to the specific phase of evolution of the hip understood to be dynamic reality.
