nails it

Every day people all over the world break large bones in their bodies – whether from skiing, car accidents, or just slipping and falling. Fractures in upper arm, thigh, hip, and lower leg are treated with intramedullary (IM) nails – a type of implant manufactured with great care and precision by Tegra Medical.

A different kind of nail

When you think about a regular nail, you probably picture a straight, solid piece of metal, ready to be pounded into wood. But it is a very different story for intramedullary (IM) nails, one of the implants that Tegra Medical manufactures.

During surgery, the doctor drills a hole into the medullary cavity of a broken bone and then inserts a long titanium IM nail into the hole. The nail is then screwed into place, holding the broken pieces together securely so they can heal properly.

More complicated than they look

Compared to other medical devices IM nails do not look extremely complex. But they are complicated to manufacture. Because they are inserted into bones, they must have absolutely precise anatomical bends. To aid the surgeon they can include advanced features that enable fewer revolutions and less torque during the surgical insertion procedure.

Ten patients with broken tibial bones might need ten different sizes of IM nails. This means we manufacture many different sizes in varying amounts. Each size requires its own precise bend tailored to the bend of a person’s bone. As medical implants, every IM nail must meet stringent quality standards.

Bending over backwards

Manufacturing the precise anatomical bend in an IM nail can be a challenge for some manufacturers. The bend is needed right where the nail also changes its diameter and where there are holes and slots for screws. Traditional methods of bending metal tend to damage those areas. The experts at Tegra Medical harnessed their decades of implant-making experience and created a proprietary way of bending the nails that does not damage its special features.

With all the necessary technologies under one roof – CNC milling, Swiss turning (sliding head lathes), gundrilling, bending, and CMM measuring – they are well positioned to manufacture components and complete IM nail assemblies. While other manufacturers may get bent out of shape over the complexities of IM nails, Tegra Medical has nailed down a process that is hard to beat.
