Rehabilitation after hip disarticulation and hemipelvectomy amputations can be challenging, and many opt to forego prosthetic limb use. There is limited evidence on characteristics that result in successful prosthetic use; therefore, our study aimed to identify these to help guide patient expectations.
A retrospective review was performed on patients seen at a UK tertiary prosthetic center in the past 5 years with hip disarticulation or hemipelvectomy amputations. Details and etiology of amputation, length between assessment and delivery of prosthesis, goals, reasons for abandonment, and outcomes were recorded. Successful prosthetic use was defined as the use of a prosthesis at least 3 times a week. Characteristics were compared using odds ratios and Fisher exact test.
Twenty-seven patient notes were analyzed: 42% female, 58% male, and age range 14-90. Thirty percent had a hemipelvectomy, and 70% had a hip disarticulation. Neoplasia accounted for 78% of etiologies followed by trauma 15% and infected endoprosthesis 7%. Sixty-seven percent trialed a walking prosthesis; 33% of these stopped eventually. There were no statistically significant findings of factors increasing odds of successful prosthetic use. However, age significantly increased the odds of being given a trial of a prosthesis.
Although younger patients are more likely to be given the opportunity to trial a walking prosthesis, age does not seem to affect the overall outcome alone. In cases of neoplasia, there is often a delayed start to rehabilitation and prosthetic use, which may affect eventual success. Further studies are required to define the optimum characteristics for successful prosthetic use at higher amputation levels.
