Abstract: A minimally invasive hip arthroplasty technique involves intramedullary insertion of an elongate femoral broach into a femur. The broach has a superior lateromedial transverse bore. A reaming rod is then located through the transverse bore and the neck of the femur. A cutting head is coupled to a distal end of the reaming rod via an incision. An orthogonal drive arm of an arthroplasty jig may also be inserted behind the cutting head to press the cutting head to ream the acetabulum while the reaming rod rotates the cutting head.

Abstract: A surgical filament securement assembly has an anchor having a channel therethrough through which a surgical filament is passed. The surgical filament is tied to form a dilated knot having at least one throw around a dilater member at an entrance of the channel such that the surgical filament is able to run around the dilater member when a limb thereof is pulled in a first direction through the channel whilst the dilated knot remains in place. When the dilater member is pulled out from within the dilated knot, the dilated knot itself strangulates to form a tightened stopper knot. The channel has a diameter less than that of the tightened stopper knot such that the tightened stopper knot cannot pass through the entrance in the first direction.
