Prosthetic fitting in a patient with a transtibial amputation due to a congenital vascular malformation of the right leg.

Background: The problems of prescribing a prosthesis for a young girl with severe congenital vascular malformation deformity leading to a transtibial amputation. Case description and methods: Due to the high risk of recurrent bleeding and limitations regarding full weight bearing of the stump, a normal socket fitting process was not possible. Using a multidisciplinary approach, a prosthesis was designed to enable full weight bearing in a flexed knee position with ischial tuberosity support to prevent full weight bearing on the tibial part of the stump. Findings and outcomes: After training and adjustments to the design, a definitive prosthesis with a free motion mechanical knee joint could be used. During the training with this prosthesis, no skin problems were observed, and at the end of the rehabilitation, the patient had a high level of activities of daily living and sports. Conclusion: The above prosthetic solution with an adjusted socket design proved to be successful in this case. Clinical relevance In a patient with severe congenital vascular malformation deformity leading to a transtibial amputation, fitting of a good prosthesis without full weight bearing of the stump proved to be successful.
