A new osteotome for performing chevron trochanteric osteotomy.

We report on the use of a new modified osteotome for performing chevron trochanteric osteotomy during hip arthroplasty. It is easy to use and the apex of the chevron is directed distally, thus producing a large segment of osteotomized trochanter, while avoiding the problems of fragmentation and splintering. At the end of the procedure, the trochanter is easily seated back within its concave bed, automatically achieving anatomical reduction and allowing easier fixation using the cruciate wiring technique. In a series of 77 primary hip arthroplasties, bony trochanteric union was achieved within 6 months in all patients.
