Hip disarticulation (HD) and Hemipelvectomy (HP) are the most proximal amputations of the lower extremity. Although the two amputation levels are similar in appearance they feature important anatomical differences; Whilst a HD is performed directly through the hip joint, a HP includes removal of the entire hip joint along with a section of the pelvis on the same side
Because of the extent of HD and HP amputations, they can significantly impact functional mobility and independence. Coupled with an increased likelihood of chronic pain and skin complications,individuals with these proximal amputation levels tend to experience the most difficulty in activities such as walking, rising and sitting down and climbing stairs.
Despite the challenges associated with rehabilitation, prosthetic fitting for HD and HP amputees should not be discouraged.
Modern advancements in prosthetic design have seen the development of lighter and more functional lower limb components, including some specifically designed for HD and HP prostheses. Socket designs have also evolved to incorporate more modern interface materials such as silicone, that conform more closely to the individual's anatomy thus providing improved fit and comfort for the prosthetic user. HD and HP prostheses, particularly those incorporating modern designs and components, can help restore functional mobility to a higher level as well as benefit a more diverse demographic of amputees.
A thorough physical assessment of the individual is essential as it can help can guide the selection of components, with careful consideration to the their personal requirements and activity level.
Another method to help aid stability is to shorten the overall length of the prosthesis by approximately 1cm compared to the contralateral limb. This allows for additional toe clearance during the swing phase of gait, although depending on the components used, this compensation may not always be necessary
