Abstract
Introduction: We report the early results of the hydroxyapatite coated, distally locking Cannulok revision hip prosthesis. The component was used to treat difficult periprosthestic and pathological fractures, often in the presence of aseptic loosening or infection in a group of elderly patients.
Methods: 16 patients with a mean age of 78 years underwent surgery by a single surgeon over a period of 3 years. No patients have been lost to follow-up and they have been followed up clinically and radiologically for an average of 24 months.
Results: The mean modified Merle D’Aubigne and Oxford Hip Scores were 14 and 23.6 respectively. These results are comparable to the published results for the previous uncoated version of the Cannulok hip, and other revision hip series.
Discussion: We believe the HA coated distally locked Cannulok revision hip implant provides a relatively simple and effective reconstructive option that can be used as an alternative to more extensive surgical options in elderly patients with periprosthetic fractures.
