Tibial fractures involving the ankle in children. The so-called triplane epiphyseal fracture.

Triplane fractures of the distal end of the tibia in fifteen children (average age, thirteen years) represented 6 per cent of 237 consecutive epiphyseal fractures of the ankle. Thirteen children were treated by closed methods (including manipulation) and two had open reduction of the fractures. At an average of twenty-six months after injury, three of fourteen patients showed roentgenographic evidence of premature symmetrical epiphyseal closure with less than 0.5 centimeter of shortening and no angular deformity. Of twelve children examined clinically, three had a 5 to 10-degree external rotation deformity and one patient also had an articular incongruity due to inadequate reduction. In the five cases in which tomograms were used to the medial malleolus, and the anteromedial part of the epiphysis. The lateral fragment included the remainder of the epiphysis together with a piece of posterior metaphysis with attached fibula.

Microscopic examination of a naturally occurring epiphyseal plate fracture.

We had the opportunity to examine a naturally occurring Salter-Harris Type I fracture in the distal tibia of a 9-year-old boy. The injury was simultaneous with traumatic amputation of the extremity a few centimeters distal to the knee. The epiphyseal plate was examined microscopically, and the plane of cleavage was found not to be uniform, but to involve the zones of resting, proliferating, hypertrophying, and provisionally calcified cartilage cells. We hope by demonstrating the inconsistency of the cleavage plane in this case to assist in understanding the complexity of physeal fractures and the unpredictable results that occasionally occur.

Factors relating to hip joint arthritis following three childhood diseases--juvenile rheumatoid arthritis, Perthes disease, and postreduction avascular necrosis in congenital hip dislocation.

This article discusses factors that relate to the prognosis for development of hip joint arthritis following juvenile rheumatoid arthritis (JRA), Perthes disease, and postreduction avascular necrosis in congenital hip dislocation (CDH). In JRA, the integrity of the articular cartilage determines prognosis. In Perthes disease, prognosis is strictly related to the shape of the hip. In postreduction avascular necrosis in CDH, half the patients have a prognosis primarily related to hip joint shape, and half have a prognosis apparently more related to the integrity of the articular cartilage.

Hip dislocation in spastic cerebral palsy: long-term consequences.

We evaluated 38 noninstitutionalized patients with spastic quadriplegic cerebral palsy with 51 dislocated hips. Nine hips had been reduced. The mean follow-up was 18 years, with an average age of 26 years. At follow-up, four were ambulatory with aids. Patients who could walk had normal intelligence and a level pelvis. In patients with 18 unreduced unilateral hip dislocations, pelvic obliquity and scoliosis were present in 12. In seven patients with reduced unilateral hip dislocations, similar findings were present in only two patients. Half of the dislocated hips were painful. Based on these findings, we recommend reduction of unilateral dislocations. Bilateral dislocations may benefit from reduction if treatment is undertaken before significant adaptive deformity of the femoral head occurs.

Late sequelae of septic arthritis of the hip in infancy and childhood.

We report a multicenter long-term follow-up study of patients with septic arthritis of the hip during infancy or childhood. Group I ("infantile") consisted of patients with onset before age 3 months, and Group II ("childhood") consisted of patients in whom onset occurred after age 3 months. Patients were specifically examined for this review. Generally, patients at follow-up had poor anatomic appearance radiographically and scored poorly on the Harris rating system. However, pain and activity restriction were minimal. Patients who were not treated operatively tended to function better than patients who underwent operative reconstruction.

A three-dimensional study of calcaneonavicular tarsal coalitions.

The authors studied 37 presumed calcaneonavicular tarsal coalitions from the Hamann-Todd Osteological Collection at the Cleveland Museum of Natural History. The anatomy of the coalitions and the associated subtalar and transverse tarsal joints was quite variable. The coalitions in 8 specimens completely spared the anterior facet of the calcaneus and in 7 specimens it was partially replaced by the navicular portion of the coalition, whereas in 22 specimens the anterior calcaneal facet was completely replaced by the navicular portion of the coalition. The authors suggest that the pathoanatomy of calcaneonavicular coalitions is not uniform and may involve the subtalar and transverse tarsal joints. This may have clinical relevance and contribute to the unsatisfactory results in feet undergoing coalition resection and soft tissue interposition.
