Summary
Hip disarticulation prostheses can cause discomfort. A new total contact suction socket design improved comfort, suspension, and mobility for two patients, enhancing prosthetic acceptance.
Area of Science:
- Orthopedic prosthetics
- Rehabilitation engineering
- Biomedical engineering
Background:
- Hip disarticulation is common in young individuals, often due to malignancy.
- Traditional exoskeletal Canadian Hip Disarticulation prostheses were standard, but endoskeletal modular versions are now preferred.
- The conventional 'basket-shaped' socket in hip disarticulation prostheses frequently causes patient discomfort and rejection.
Observation:
- Two patients with hip disarticulation experienced difficulties with standard prostheses.
- These patients could not adapt to the conventional 'basket-shaped' socket design.
- A novel total contact suction socket was trialed for these patients.
Findings:
- The new total contact suction socket design demonstrated improved suspension.
- Patients using the new socket design showed better compliance and acceptance.
- Enhanced prosthetic acceptance and mobility were observed with the new socket.
Implications:
- The total contact suction socket may offer a superior alternative for hip disarticulation patients.
- This design could reduce prosthetic rejection rates and improve patient quality of life.
- Further research into suction socket designs for hip disarticulation is warranted.
