Return to surfing using an adapted prosthesis: A case report.

BACKGROUND: Surfing with transfemoral knee prosthesis requires flexion of the hip, knee, and ankle and balance between flexibility and stiffness of the prosthetic limb. We report on Mr D, a transfemoral amputee, who wanted to surf again. Case Description and Methods: Technical specifications were based on Mr D's complaint. The prosthesis is salt water resistant and combines a shock absorber associated with elastic tendons to permit the knee to bend easily and to facilitate eccentric braking. Surfing was observed using videos of movements and subjective analysis of compensations. Findings and Outcomes: Mr D uses this prosthesis for surfing with good results and got back to his former level using compensations. During the takeoff, he cannot shorten his left leg. He makes a circumduction movement to put his leg in front of the board.

CONCLUSION: This prosthesis is adapted for surfing and allows precise adjustments to surfing conditions. Clinical relevance Appropriate prosthesis design can enable return to surfing for a transfemoral amputee.
