A surgical fastener assembly for coupling first and second bone portions across a fracture therebetween is disclosed. In one embodiment of the present invention, the surgical fastener assembly includes an anchor that has a first externally threaded portion disposed in the first bone portion and a second portion which is at least partially disposed in the second bone portion. At least one pin is operably associated with the first portion of the anchor such that when the pin is in a retracted position the pin is disposed within the anchor and when the pin is in an extended position at least a portion of the pin extends outward from the anchor. An actuator is disposed within the anchor and is operably coupled with the at least one pin. A guide is adapted to be fixedly secured to the second bone portion and includes a sleeve. The second portion of the anchor is received within the sleeve. A fastener is provided that has a head portion and an externally threaded shank portion. The shank portion threadedly engages with the anchor and the head portion operably engages with the guide.

The intramedullary nail system includes an intramedullary nail for insertion in the femur. The nail has an axial bore and an intersecting transverse bore. A lag screw is inserted through the transverse bore and turned into the head of the femur. A slotted sleeve is inserted over the lag screw and through the transverse bore with the slots aligned with the axial bore. A sleeve lock is inserted into the axial bore and has a locking tab which engages the slots in the sleeve preventing rotational and longitudinal movement between the sleeve and the nail. A compression screw is turned into the trailing end of the lag screw and engages the encircling sleeve to provide longitudinal translation between the lag screw and sleeve to apply compressive force across a fracture.

An intramedullary nail system for reducing and fixing fractures in long bones includes an elongated intramedullary nail having radial portals about the circumference. Tang assemblies are slidably telescoped inside the nail with resilient tangs which are deployed through the portals to interlock the nail and the portions of the bone.

Intramedullary nail

An intramedullary system for securing portions of a bone together has a lag screw assembly extending through a radial bore in an intramedullary nail. The lag screw is inserted into one portion of a bone and deployed to fix the leading end. The intramedullary nail is placed in the intramedullary canal of a portion of the bone and the trailing end of the lag screw assembly is adjustably fixed in the radial bore to provide compression between the lag screw assembly and the intramedullary nail. The intramedullary nail has a cap screw in the proximal end holding the lag screw assembly and a tang in the distal end. The tang has legs extending through the nail to fix the distal end in the intramedullary canal.

A swimming pool control system automatically controls the daily maintenance functions of a swimming pool. The control system actively monitors system conditions, makes adjustments for abnormal conditions, and provides remote feedback of system problems during its daily cycle. In addition, the control system provides operator assisted manual override operation and control of additional auxiliary equipment. The system includes a novel filter valve, a novel water level system and a novel suction valve that can be run and monitored non-manually by a digital controller.
