Abstract
We looked at the outcome of management of 16 patients (19 limb segments) with congenital fibular hemimelia treated in our unit over a 24-year period from 1978 to 2001. Eight boys and eight girls, all with associated musculoskeletal abnormalities in the lower limbs, were presented for management at or before the age of six months.
On four patients no surgery was performed. In the other 12, orthopaedic management was completed during the skeletal growth period. Primary amputations (one below-knee, one Syme and one Boyd) were performed on three patients and prostheses fitted in early childhood. Three patients with bilateral fibular hemimelia were treated initially with a Gruca ankle reconstruction procedure. Using the Ilizarov technique, we performed tibial lengthening procedures on nine patients.
At the latest follow-up, the three patients who had amputations were functioning well and had no complications. The nine patients in whom tibial lengthening was the main reconstructive procedure suffered numerous complications and all needed further corrective surgery or footwear alterations. None required or requested late amputation because of poor function or cosmesis. Analysing results by parameters such as restriction of activity, pain, complication rate, treatment costs, hospital and clinic visits, periods of absence from school, and patient satisfaction, we found notably better results among patients who underwent early primary amputation than among those who underwent tibial lengthening.
This needs to be kept in mind when advising parents of the most appropriate course of management of their child’s disorder.
