Complications following osteotomy of the greater trochanter in total hip replacement arthroplasty using the lateral approach.
In a consecutive series of 365 hip replacement arthroplasties ad modum Charnley in 309 patients migration of the trochanteric fragment was encountered in 4.9 per cent of the cases. The predisposing factors were wire-breakage, trochanteric fractures and excessive weight. Men were more apt than women to develop migration. Early mobilization with weight-bearing on the operated leg did not increase the risk of migration. The migration rarely gave rise to complaints, and if so only mild ones. Trochanteric union did not pose problems, and at the end of 2 years 98 per cent had united. After 5 years no case of non-union was detected.
