Abstract
A new surgical technique, the Barrett-Day endoscopic plantar fasciotomy procedure, is used to relieve the symptoms of heel spur syndrome. The positioning of the plantar fascia ligament is determined, and the patient is prepared for surgery. A small, vertical incision is made in the medial side of the foot, and the adipose tissue is spread. A fascial elevator is inserted into the first incision to separate the plantar fascia from the surrounding tissue, creating a channel. A slotted canula and trocar is inserted into the channel, and a second incision is made on the lateral side of the foot, allowing the canula and trocar to substantially pierce the foot. The trocar is removed, and an endoscope is inserted into the canula through the medial portal. A cutting instrument is inserted into the lateral portal of the canula, and is used to release the plantar fascia from the heel bone. Once the plantar fascia has been released from the heel bone, the instruments are removed, and a bandage is placed around heel. The procedure allows the patient to immediately bear weight on the heel after the operation is complete.
