RESUMEN
Pelvic radiographs of 25 children aged 6 months to 2 years had the acetabular index measured 3 times by each of five pediatric orthopaedists. Interobserver measurements were found to vary +/-3.0 degrees, whereas the intraobserver variation was +/-3.6 degrees. This error reflects only measurement error and does not consider error introduced with different positioning of the pelvis.

An 18-month-old girl with a distal tibiofibular diastasis secondary to an osteochondroma was seen with a valgus deformity of the ankle. The patient underwent operative excision of the osteochondroma at the age of 2 years. At 13-year followup there was resolution of the diastasis, and the patient was free of symptoms. Early excision obviates the need for complex reconstructive surgery to correct ankle deformity later.

Clinical features and radiographic findings of eight patients with dysplasia epiphysealis hemimelica are described. In all patients, a single lower extremity was involved. The most common sites of involvement were the distal tibia and the distal femur. Magnetic resonance imaging was beneficial in determining a plane of separation between the accessory ossification center and the normal epiphysis. If the lesion is extraarticular, simple excision of the mass yields favorable results. If the lesion is intraarticular, an osteotomy may be needed to correct an angular deformity. Recurrence of the deformity is common.
