Covering the below-knee amputation stump with the pedicled dorsalis pedis flap from the ipsilateral foot: a case report.

Abstract

It is important to preserve the length, appropriate durable skin, and sensation of the stump when performing below-knee amputation to achieve functional ambulation with a prosthesis. There are many reports of reconstruction procedures using microvascular surgery to preserve the optimum length of the amputation stump for prosthesis; however, free tissue reconstruction is necessary to accompany with the donor site morbidity. In this report, we describe our experience with a below-knee amputation and stump covering using the pedicled dorsalis pedis flap from the no longer usable foot in the case of a severe osteomyelitis of a lower extremity after highly contaminated Gustilo type IIIB fracture. We achieved a well-healed amputated stump with enough length for a prosthesis and for protective sensation. The pedicled dorsalis pedis flap is easily elevated without microvascular anastomosis and is one useful option for the reconstruction of the below-knee amputated stump in the specific case.
