title: Trochanter re-attachment in revision hip arthroplasty.
abstract: We present a new method of trochanter stabilisation designed for use in difficult revision hip arthroplasties. A fixator is secured to the metaphysis of the femur, and its two malleable prongs encompass the trochanter fragment and stabilise it using the tension band principle. The fixator is versatile, simple to apply and has better mechanical properties than any technique using wires. We reviewed 49 revisions after a mean follow-up of 40 months. Patients had been mobilised early, but there were no detachments or displacements from the initial postoperative position. Although 31% of patients were osteoporotic and 16% had poor trochanter fragments, there was bony union in 46 of the 49 hips, the remaining three developing stable fibrous union.
