Abstract
New surgical instrumentation and a new surgical procedure is used for decompression for Morton's neuroma. The patient is prepared for surgery. An incision is made in the dorsal aspect of the foot, another incision is made between the digits of the foot, and then another incision is made on the bottom of the foot. A metatarsal spreader or retractor of the present invention can be inserted through the dorsal incision to spread the metatarsals. A slotted cannula and trocar assembly of the present invention is inserted into the interdigital portal and through the proximal portal. The trocar is removed and an endoscope is inserted into the cannula through the dorsal portal. A lumbrical hook of the present invention is inserted into the proximal portal of the cannula and used to hook the lumbrical tendon. A hook blade is used to sever the intermetatarsal ligament. Once release of the intermetatarsal ligament has been achieved, the instrumentation is removed and a bandage is placed about the foot.
