Biorigid Nail™ Tibia

With its Biorigid Nail™ Tibia unreamed tibial nailing system, aap has set new standards in the biological osteosynthesis of fractures of the lower leg. The new patented concept of interlocking grooves permits the use of stable 4.5 mm interlocking screws while increasing the load-carrying cross-section to more than 50% above that of implants with central holes. The advantages of this concept are reflected in an extremely low implant failure rate of less than 0.1 percent.

Wider range of indications

The Biorigid Nail™ Tibia can be used to treat indications ranging from simple, closed fractures to complex open, comminuted fractures. At the same time, the proximal AP locking and the interlocking grooves at the distal extremity permit the treatment of fractures ranging from those at the passage from the middle to proximal third of the tibia to diaphyseal fractures and fractures close to the ankle joint. Where the soft tissue is badly damaged and primary treatment is with an external fixateur, the Biorigid Nail Tibia permits an early change of procedure to intramedullary fracture stabilization, which is easy on the patient and reduces the risk of infection round the fixation pins.

Ultra-biocompatibility

The Biorigid Nail™ Tibia is made from a titanium alloy (TiAl6V4) with elastic properties that more closely approximate those of the human bone than do those of other metallic materials. Its non-allergenic, bio-inert behaviour guarantees outstanding biocompatibility and provides a high degree of protection against nickel allergies.

Optimized operating technique

The X-ray-free distal targeting device meets the demand of users to reduce X-ray exposure. It enables precision distal targeting to be maintained even if the nail implant becomes elastically deformed.

Gentle implantation

There is no need to drill open the medullary cavity. This reduces the associated risk of heat necroses and fat embolisms.

The distal extremity of the Biorigid Nail is very rounded and fitted with a dorsal runner.

This prevents the nail from becoming stuck during insertion into the medullary cavity. At the same time, the longitudinal dorsal groove relieves the pressure in the medullary space during implantation. The arteria nutricia that runs close to the groove is also relieved, so vascularization of the bone is not impeded.

Early patient mobilization

The ultra-stable Biorigid Nail permits early mobilization of the patient, with full weight-bearing capacity after just one week on average. Because of the system's reduced stiffness (biorigidity), there is no need for a second surgical intervention for early removal of the fixation elements (dynamization).
