A marked cannula is disclosed that provides for first and second indicia for marking positions along the inner surface of the cannula. The first and second indicia are distinctive with respect to each other and are easily detected or visible using an endoscope. The first and second indicia are preferably provided at positions that are representative of the general population in terms of location of the plantar fascia. The indicia provide a quick visual reference for the positioning of a surgical instrument within the bore of the cannula.

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.

Instrumentation and surgical procedure for decompression for Morton's

A firearm support is provided with a receiving and attachment means for receiving the firearm and securely holding it. The attachment means engages with the sling mount bolt of a firearm and draws the firearm and firearm support tightly but releasably together. The attachment means includes gripping arms with pins that engage a sling bore in the sling mount bolt. The attachment means also includes a fixed body or neck with an inner bore that receives the sling mount bolt and gripping arms. The inner bore has an elongate camming surface to engage an outer surface on the gripping arms for urging the pins into the sling bore and holding them in place as the gripping arms and sling mount bolt are pulled into the inner bore. The firearm support includes a telescoping leg that has an internal lock to maintain the leg in a closed or carrying position with respect to the firearm. Adjustment means are provided to position the telescoping leg substantially parallel to the barrel of the firearm when in the folded carrying position.
