What is primarily used for suspension in a hip disarticulation prosthesis?

In a hip disarticulation prosthesis, the iliac crest plays a central role in suspension due to its stability and anatomical positioning. The iliac crest provides a secure anchoring point for the prosthetic socket. By utilizing the bony anatomy of the pelvis, the socket can achieve better load distribution and enhanced proprioception for the wearer.

This anatomical feature is particularly beneficial in hip disarticulation cases, where traditional suspension methods, such as thigh cuffs or pelvic bands, may not offer the same level of security or comfort. The socket's design incorporates the iliac crest to form a more integrated system that supports the prosthesis during ambulation and various activities while also ensuring optimal performance and control. This connection to the pelvis allows the user to have a more natural movement pattern and enhances the overall stability of the prosthetic device.
