Hallux Rigidus and Friebergs Disease

Hallux Rigidus is an arthritic condition leading to pain and stiffness in the great toe. The first stage of surgical treatment is traditionally a chielectomy, and this has traditionally been followed by fusion if the symptoms persist. Friebergs Disease involves a loss of blood supply metatarsal head, leading to eventual collapse of the joint surface.

Fusion in the forefoot is an excellent procedure for providing pain relief, however it does restrict activity such as running and the wearing of high heeled shoes. Preserving motion in the forefoot therefore extremely appealing, however it is a challenge due to the wide range of forces applied on the joint and the limited amount of bone stock available.

The HemiCAP MTP implant is the most anatomic and bone sparing option available to surgeons. With very positive short to mid-term results, the HemiCAP implant uses the patented Arthrosurface intra-operative mapping technology to replicate the curvature of the metatarsal head in both planes. It requires a minimal amount of bone resection on the metatarsal head, while the phalangeal side is left completely intact.

The HemiCAP MTP replacement is quickly becoming established as the first choice joint replacemet for the MTP. If you would like to know more about the implant, please follow the Arthrosurface link to the right hand side of this page. If you are a clinician and would like to learn about the implant in more detail, please contact your local NorthStar Area Manager. One of the best ways to learn the surgical technique is to carry out a sawbones implantation, which can also be arranged through your Area Manager.
