Femoral neck fractures are the most common human bone fractures.

Many femoral neck fractures are treated by intramedullary hip nailing: surgically implanting a short femoral nail (SFN) with the nail shaft being inserted into the intramedullary cavity of the femoral shaft, and a lag screw being inserted into the femoral neck and ball.

The human femoral neck and ball are positioned approximately 4mm to the anterior of the femoral shaft. Existing SFNs does not include this displacement. Consequently, post-operative imaging shows that SFNs are positioned incorrectly in many patients, leading to the femoral neck bone fragment being displaced posterior to the femoral shaft bone fragment. This causes undesirable outcomes: large telescope, in which one bone fragment slips inside the other; and cut-out, in which the lag screw, due to improper positioning, protrudes from the femoral ball.

BFN Research has developed a new short femoral nail, the Best Fit Nail (“BFN”) for treating femoral neck fractures. The BFN’s lag screw is displaced anterior to the nail shaft conforming to the shape of the human femur and solving the design shortcoming of conventional SFNs.

BFN is licensed for surgical use in Japan and is available to surgeons and hospitals. In Japan, BFN has been implanted in more than 200 patients, with markedly improved results compared to straight SFNs, as demonstrated in clinical trials.

BFN Research seeks to license its patents and registered designs to one or more companies to make the BFN nail available worldwide for the benefit of femoral neck fracture patients.
