Summary
A novel transmetatarsal amputation prosthesis with a carbon-fiber plate significantly improved gait patterns in patients. This innovative footwear offers a viable alternative for individuals with transmetatarsal amputations.
Area of Science:
- Biomechanics
- Prosthetics
- Orthopedics
Background:
- Transmetatarsal amputation (TMA) presents challenges in restoring normal gait.
- Existing footwear solutions may not adequately address the biomechanical needs following TMA.
Purpose of the Study:
- To evaluate the efficacy of a newly designed transmetatarsal amputation prosthesis incorporating a carbon-fiber plate.
- To assess the impact of this prosthesis on gait patterns in TMA patients.
Main Methods:
- A gait analysis was conducted in a laboratory setting.
- Eight male patients with TMAs and nine able-bodied male volunteers participated.
- Footwear included a standard shoe and the novel TMA prosthesis with a carbon-fiber plate, custom insole, and toe filler.
Main Results:
- Kinetic and kinematic studies demonstrated significant improvements in gait parameters after using the prosthesis.
- The prosthesis design did not necessitate extensive shoe modifications for insertion.
Conclusions:
- The transmetatarsal amputation prosthesis with a carbon-fiber plate significantly enhances gait in TMA patients.
- The integrated carbon-fiber plate mimics a shoe shank, improving foot function.
- This prosthesis represents a promising footwear option for individuals with transmetatarsal amputations.
