METHOD AND SYSTEM FOR PERFORMING ENDOSCOPIC SURGERY AT LOCATIONS WHERE TISSUE INSERTS INTO BONE Abstract of the Disclosure An endoscopic system and method for performing endoscopic surgery at locations where tissue inserts into bone which includes a sleeve member, obturator, cutting and excision instruments, and a marking and insertionassembly wherein the sleeve member has an expanded portal through which instrument access and improved visualization can be performed at arcuate lines of insertion of tissue into bone. The sleeve member can include a flange for engaging tissue along the line of insertion and exposing the bone and measurement means for gauging precisely the reduction or resection of bone. An alternative embodiment of the sleeve member has a non-uniform aperture with an instrument portion and a register portion providing increased space and maneuverability forinstruments when opening at the portal on tissue or bone that can include the flange. Cutting instruments are provided with an extension portion to extravasate from tissue and palpitate underlying tissue. An marking and insertion assembly for use in heel surgeries to remedy plantar fasciitis and in conjunction with a lateral radiograph provides precise location of an entry incision and precise medial to lateral insertion of a guide wire forming a channel for the sleeve member. The method and system also provides for minimal incision surgery in the caudal release of the plantar fascia and reduction of a spur on the os calcis.
