Original articleWalking Ability and Quality of Life in Subjects With Transfemoral Amputation: A Comparison of Osseointegration With Socket Prostheses
Section snippets
Methods
Subjects with transfemoral amputation recruited for this study were referred to the outpatient clinic from the university medical center. All subjects were referred because socket-related skin and residual limb problems were contributing to limited prosthesis use. An inclusion criteria instrument for OIP was developed based on the following items: prosthesis use, prosthetic mobility, problems, and global score of a Dutch translation of the Questionnaire for Persons With a Transfemoral
Results
Between May 2009 and May 2011, 22 subjects who had undergone transfemoral amputation because of trauma (n=20) or a tumor (n=2) participated in this study. Twenty-one participants had unilateral transfemoral amputation, and 1 participant had bilateral transfemoral amputations. The mean age ± SD of the study group was 46.5±10.7 years (range, 23–67y) and included 18 men and 4 women. At the time of inclusion, the participants were at an average ± SD of 16.4±14.8 years after amputation (range,
Discussion
In this prospective case-control study, we report that OIP improved walking ability and quality of life in subjects with transfemoral amputation who initially presented with socket prosthesis–related skin and residual limb problems. In summary, subjects with OIP were capable of walking further faster while using 18% less energy. In addition, they had significantly better prosthesis-related quality of life compared with their previous situation with the socket prosthesis. Participants with OIP
Conclusions
Osseointegration is a suitable intervention for individuals with transfemoral amputation performed because of trauma or tumor, who have reduced prosthesis use as a result of socket-related residual limb/skin problems. In 1-year follow-up, subjects with OIP significantly increased walking ability and prosthesis-related quality of life.
