ABSTRACT:
A preassembled disposable driver and suture anchor are provided for threaded engagement into a bone to provide an attachment point for soft tissue. The anchor is formed to have an externally threaded body portion for engaging the bone, a distal end portion, and a proximal end portion. When the anchor is threaded into an opening in a bone, the distal end portion is adjacent a bottom of the opening and the proximal end portion is adjacent a mouth of the opening. A suture is attached to said anchor having free ends extending outwardly from the bone opening. The driver is elongated and has a distal end which engages the proximal end of the anchor and a proximal end for gripping by the surgeon. The driver also has a slot for receiving the suture which extends away from the anchor. The distal end portion of the driver is radially enlarged relative to the body portion of the anchor to engage the bone surrounding the mouth of the opening to limit the internal advancement of the driver such that further rotation and threading of the anchor into the bone by the driver will separate the anchor from the driver.
