In hemipelvectomy socket principles, what is emphasized for weightbearing?

In hemipelvectomy socket principles, the emphasis on weightbearing is placed on the iliac crests and impaired areas. This approach is crucial because the iliac crests provide a bony structure that can effectively transmit loads and support the prosthesis during weightbearing activities. By focusing on these areas, the socket can achieve better stability and distribute forces across the residual limb, facilitating a more functional and comfortable fit for the user.

The rationale behind this emphasis includes the need to maximize support from the available bone, as well as to avoid unnecessary pressure and discomfort in softer tissues or areas that may be more vulnerable post-surgery. This strategy reduces the risk of skin breakdown and enhances the overall functional capability of the prosthesis.

Other options, while they may have relevance in different aspects of rehabilitation or prosthetic fitting, do not prioritize the critical role that the iliac crests and impaired areas play in providing a stable foundation for weightbearing in hemipelvectomy cases. Focusing on other structures, such as the thigh and knee joints or muscle groups around the hip, may not align with the unique considerations of a hemipelvectomy, where the primary support structure is significantly altered.
