A case of an elderly hip disarticulation amputee with rheumatoid arthritis who regained the ability to walk using a hip prosthesis

Abstract

[Purpose] We report a case of an elderly patient with rheumatoid arthritis who underwent hip disarticulation because of necrotizing fasciitis and regained the ability to walk independently with a prosthetic limb. [Participant and Methods] A 61-year-old female patient underwent right hip disarticulation due to severe necrotizing fasciitis of the right lower limb. Her chief complaint was that she was not able to walk inside her house or outdoors to perform instrumental activities of daily living. We applied a Canadian-type hip disarticulation prosthesis to the stump. The patient received in-hospital physical therapy, occupational therapy, and clinical psychology counselling for 145 days. As her hands and fingers were weakened by rheumatism, we made several modifications to the prosthesis to enable the patient to attach and detach it independently. [Results] The patient was able to use the prosthesis to walk continuously for 45 m, perform various housework duties, drive a car, and go out, thus accomplishing the desired daily activities. [Conclusion] Our patient, an elderly hip disarticulation amputee with rheumatoid arthritis, was able to walk independently using a prosthetic limb. The application of prosthetic limbs may be appropriate even for hip disarticulation amputees with comorbidities that make it difficult to acquire a prosthetic gait.
