Abstract

Introduction

There has not been any study regarding comparative gait analysis in patients with intramedullary stemmed prosthesis (ISP) and thrust plate prosthesis (TPP) implanted to each hip.

Patients and methods

Four patients (three females and one male) who had undergone operation due to coxarthrosis were selected. The mean age was 60.5 (37–78) years. TPP and ISP had been implanted to the left and right hip, respectively, in three patients, and one patient received TPP to the right and ISP to the left hip. Gait was analyzed with a BTS Elite System consisting six cameras and two Kistler force plates using Helen Hayes marker set to assess the gait parameters. The clinical outcome was also evaluated according to Harris hip score (HHS).

Results

The average HHS was 95.0 (82–100) points after a mean follow-up of 45.0 (30–50) months for TPP and 94.5 (80–100) points after a follow-up of 60.0 (14–122) months for ISP. Neither of the HHS scores and follow-up time nor gait parameters obtained from the TPP-implanted side were statistically different when compared to those of the ISP-implanted side.

Conclusion

TPP and ISP as the implants with their own biomechanical specifications did not produce any remarkable difference in gait.
