A NEW OSTEOTOME FOR PERFORMING CHEVRON TROCHANTERIC OSTEOTOMY

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