SUMMARY
Purpose: rickets-like deformities of the lower limb (knock-knee or bow-leg) are very frequent in sub-Saharan Africa.Methods: A prospective study was carried out over a period of 5 years. Forty children were treated surgically for rickets-like deformities. The surgical technique was guided growth using a tension-band plate (eight plate).Results: The deformity was bilateral in 33 cases and unilateral in 7 cases (73 knees). The deformities were knock-knees in 20 cases, bowlegs in 18 cases and there were 2 windswept deformities Good correction was obtained after a mean time of 11.4 months for genu varum and after a mean time of 12.4 months. The two windswept deformities were corrected after 8 and 9 months respectively.Conclusions: the guided growth technique using eight plate is effective as well in Africa. The needed material is not expensive if a two-hole tubular plate is used with two screws.
