Growth disturbance of distal epiphysis of the lower leg may affect the carring angle of the ankle joint, causing varus and valgus deformity.
The authors experienced 4 cases of varus deformity after fracture and a case of valgus deformity resulted from defect of the fibula caused by orteomyelitis. The ages ranged from 6 to 14 years.
In 2 patients, one of which was operated on by supramalleolar osteotomy and the other by the same osteotomy with short term Blount's stapling of the distal fibular epiphysis, the deformities recurred within 2 yeare. The other 3 patients were treated by supramalleolar osteotomy combined with epiphyseal arrest by means of 8-figure wiring, which are thought to be encouraging
Discussions were made on shortening of the leg, cosmetic aspects, changes of weight-bearing axis and ages necessitating epiphyseal arrest.
