Distal tibiofibular bone-bridging in transtibial amputation

Area of Science:

• Orthopedic Surgery
• Rehabilitation Medicine
• Biomedical Engineering

Background:

• Transtibial amputation is a common procedure for lower-limb loss.
• The distal tibiofibular bone-bridge technique is a surgical modification aimed at improving outcomes.
• Its efficacy remains debated among specialists.

Purpose of the Study:

• To evaluate the functional outcomes of the distal tibiofibular bone-bridge technique in transtibial amputations.
• To compare patient-reported quality of life with traditional amputation methods and international bone-bridge procedures.

Main Methods:

• A prospective study of twenty patients undergoing transtibial amputation with bone-bridging.
• Utilized the Prosthesis Evaluation Questionnaire (PEQ) for quality of life assessment.
• Compared results to a historical control group and a Brazilian cohort.

Main Results:

• Patients in the American bone-bridge group reported similar outcomes to the control group.
• Outcomes in the American group were not as favorable as in the Brazilian bone-bridge group.
• Lower scores were observed in Social Burden, Ambulation, Frustration, Sounds, Utility, and Well-Being domains for the American bone-bridge and control groups.

Conclusions:

• The distal tibiofibular bone-bridge technique did not demonstrate superior functional outcomes compared to standard transtibial amputation in this cohort.
• Current evidence does not support the routine recommendation of the bone-bridge technique.
• Additional studies are necessary to validate the benefits of this surgical approach.
