Abstract
A wedge for insertion to a rectilinear slot in bone fastens tissue for continuous refastening of separated tissue from bone. When viewed in plan toward the proximal truncated top, the wedge is sinusoidal in shape defining a series of prominences and depressions relative to the elongate slot. At the proximal end, suture fastening apertures--preferably elongate parallel to the proximal end--are placed for looping tissue fastening sutures prior to wedge insertion. A plurality of barbs--preferably placed at the prominences--together with the compression of the wedge within a rectilinear slot cause anchoring to bone upon wedge insertion to the rectilinear slot prepared within the bone. Skewering tips at the end of the wedge enable skewered tissue to be entrained with the wedge into the bone upon insertion of the bone within a previously prepared rectilinear slot. The wedge is mounted to an inserting probe and any optional sutures organized along the length of the probe. Thereafter, and utilizing the inserting probe, flesh to be inserted is conventionally "teased" onto the skewering tips and the wedge(s) inserted utilizing the probe. Fastening of the tissue entrained by the wedge within …
