Crutch design for a high-level amputee.
The Medical Journal of Australia
|November 13, 1976
Summary
This case study introduces a novel crutch design for a high-level leg amputee, significantly improving mobility and reducing hip and foot issues. The new design addresses excessive pelvic movement by optimizing crutch placement for enhanced lateral stability.
Area of Science:
- Orthopedics
- Biomechanics
- Prosthetics and Orthotics
Background:
- A 61-year-old patient with a 33-year-old high-level left-leg amputation experienced persistent hip and foot problems.
- Previous use of unsatisfactory crutch designs led to complications and limited mobility.
Observation:
- Gait film analysis revealed excessive lateral pelvic movement during ambulation.
- The patient's biomechanical gait pattern indicated a need for improved stability.
Findings:
- Analysis of lateral stability suggested a medial shift of approximately 5 cm for the crutch support on the ground.
- A redesigned crutch incorporating this adjustment was developed and implemented.
Implications:
- The novel crutch design led to a significant improvement in the patient's condition and mobility.
- This case highlights the importance of optimized assistive device design for amputees.
- Further research into biomechanically informed crutch modifications could benefit individuals with similar mobility impairments.
