Arthrodesis of the ankle joint with complete removal of the distal part of the fibula: experience with the transfibular approach and three different types of fixation.
In 20 patients the following 3 techniques have been used for ankle fusion, all with a lateral transfibular approach: (1) fibular grafting; (2) lateral removal of the distal fibula and fixation with 3 Blount staples; (3) removal of the distal fibular and fixation with Charnley compression clamps. The compression technique, through a lateral approach, was found to be superior as it avoids section of tendons. Removal of the distal portion of the fibular eliminates the risk of drainage and problems with wound healing due to the presence of a large bone graft immediately underneath the skin. Fusion is obtained more rapidly with the third than the first and second techniques. Pain seems to be related to osteoarthritis of the surrounding joints. The gait pattern depends not only on pain, but also on the position of the foot and on the posterior displacement of the talus. Less osteoarthritis as a result of shorter immoblizaition is the most favorable factor, notwithstanding the longer preoperative period in the third than in the first two methods.
