Thesis Title:
How Important is Length? Mechanical Testing and Measurement of a Cemented, Polished, Tapered Femoral Implant.

Citation:
Despite the excellent clinical performance of cemented, polished, tapered femoral implants, they currently can not be offered to all patients due to variations in femoral anatomy. The thesis has shown that a reduction in implant length is possible without a significant compromise in stability and therefore shorter implants should be well tolerated, extending the scope of their clinical use. A tightly controlled mechanical testing model was developed to assess a range of implants and to define their geometric profile. The major findings are that for a given proximal body size, a reduction in implant length has no effect on the torsional stability of a polished, tapered design, while a small reduction in axial stability should be expected.
