Résumé

Background The conventional method of attachment of prosthesis involves on a socket. A new method relying on osseointegrated fixation is emerging. It has significant prosthetic benefits. Only a few studies demonstrated the biomechanical benefits. Purpose The ultimate aim of this study was to characterise the functional outcome of transfemoral amputees fitted with osseointegrated fixation, which can be assess through temporal and spatial gait characteristics. The specific objective of this preliminary study was to present the key temporal and spatial gait characteristics. Methods Four male transfemoral amputees fitted with a fixation were asked to performe 3 trials of straight level walking. The speed of walking, cadence, duration of gait cycle, support and swing phases, length of stride and step, and walking base were extracted from displacements of foot markers using a 3D motion analysis system recording at 200 Hz. Results The speed of walking and the cadence were 0.81±0.16 m/s and 46.03±4.70 steps/min, respectively. The duration of the gait cycles, support and swing phases were 1.31±0.13 s, 0.76±0.07 s and 0.55±0.07 s, respectively. The stride and step length, and walking base were 1.29±0.09 m, 0.10 ± 0.65 m and -0.09 ± 0.138 m for the prosthetic leg, and 1.31±0.07 m, 1.00±0.64 m and 0.11 ± 0.12 m for the sound leg, respectively. Conclusion The results demonstrate that the amputees fitted with an osseointegrated fixation showed a highly functional walk compared to normative data presented in previous studies focusing on amputees fitted with a socket and able-bodied.
