Sir,I read with great interest the article entitled “subtrochanteric valgus osteotomy in developmental coxa vara” by T El-Sobky published in the Indian Journal of Orthopedics.1 We appreciate the authors for their good work but certain key points of their report are not clear. The authors stressed only the merits of Y-shaped osteotomy over the classic V-shaped osteotomy. However, they did not clearly provide it, based on several parameters such as2 subtrochanteric fusion rates,3 effect on leg length,4 effect of one degree of deformity correction on leg length, and finally5 the fate of the corrected femoral neck-shaft angle. The final shape of the neck at the time of growth maturity is a reliable indicator of successful management.67As far as the clinical experience of this reader on subtrochanteric closing and opening osteotomy 2 of the same disease is concerned issues were, frequently (a) delayed union,3 (b) higher loss of correction at early post-operative stage, and4 very little effect on leg length. Also it was already a known fact that the corrected deformity remodel to original shape at maturity. According to Shopner et al., in cases of intertrochanteric osteotomy, the corrected neck-shaft angle remodel to the original shape within three years; which in cases of the subtrochanteric osteotomy takes six to eight years. The early loss of correction is due to union failure at osteotomy site or fixation failure, while the gradual loss of correction is due to natural remodeling. The average followup is also not clear. The final success should be made by the final neck-shaft angle and leg length at the time of growth maturity.
