Alendronate Improves Screw Fixation in Osteoporotic Bone
The Journal of Bone & Joint Surgery, 2007Animal studies have demonstrated the efficacy of the use of bisphosphonates to enhance screw fixation in bone. In this prospective, randomized study of pertrochanteric fractures treated with external fixation, we tested whether systemic administration of bisphosphonates would improve the fixation of hydroxyapatite-coated screws implanted in ...

T-Screw. A new bone fixation device
Journal of the American Podiatric Medical Association, 1989The T-Screw was patented in 1984. A 5-year study was begun in 1980, and FDA approval was granted in 1985. Detailed results of this clinical study will be reported in a later paper. The purpose of this paper is to introduce the device. The authors have found that early return to normal function and wearing shoes has been possible when using T-Screws for

Cortical bone trajectory for lumbar pedicle screws
The Spine Journal, 2009Achieving solid implant fixation to osteoporotic bone presents a clinical challenge. New techniques and devices are being designed to increase screw-bone purchase of pedicle screws in the lumbar spine via a novel cortical bone trajectory that may improve holding screw strength and minimize loosening. Preliminary clinical evidence suggests that this new

Predicting cancellous bone failure during screw insertion
Journal of Biomechanics, 2013Internal fixation of fractures often requires the tightening of bone screws to stabilise fragments. Inadequate application of torque can leave the fracture unstable, while over-tightening results in the stripping of the thread and loss of fixation. The optimal amount of screw torque is specific to each application and in practice is difficult to attain

Bone screws and plates in orthognathic surgery
International Journal of Oral Surgery, 1982The almost universal use of bone plates and screws in orthognathic surgical procedures is surveyed. Based upon considerable personal experience, it is advocated that this technique should be used for better stabilization of the fragments, leading to faster bone healing and therefore to less relapse.

A bone screw (10) which can be anchored in the bone in a firm and vacuum-tight manner, and the use of the same in arthroplastic surgery and as a drug delivery system. The interior of the bone screw (10) has a continuous longitudinal bore (15) through which the medullary canal can be evacuated during the application of bone cement.
