Dorsal Approaches for Isolated Midfoot Joints
The most common reason for using this approach to isolated midfoot joints is osteoarthritis. Removal of osteophytes or fusions are the most frequent procedures carried out through these approaches. Isolated midfoot fusions require small, precise approaches. The approaches are very specific to the requirements of the treatments, and the incisions need to be carefully planned. Fluoroscopy is often helpful in ensuring precise localization of the skin incision.
Position of the Patient
Many approaches on the dorsum of the middle part of the foot are possible. Depending on which midfoot structures are being approached, a sandbag may be used to help position the foot in a more internally rotated position (see Fig. 7-1). After exsanguination, apply a tourniquet to the middle of the thigh.
