Hallux rigidus

Although the condition is degenerative, it can occur in patients who are relatively young, particularly active sports people who have at some time suffered trauma to the joint (turf toe).

In 1988, Hattrup and Johnson described the following radiographic classification system: Early treatment for mild cases of hallux rigidus may include prescription foot orthotics, shoe modifications (such as a pad under the joint, and/or a deeper toe box[4] to take the pressure off the toe and/or facilitate walking), specialized footwear ('rocker-sole' shoes), medications (anti-inflammatory drugs) or injection therapy (corticosteroids to reduce inflammation and pain).

Physical therapy programs may be recommended, although there is very limited evidence that they provide benefit for reducing pain and improving function of the joint.

Stage 2 hallux rigidus involves greater loss of range of motion and cartilage and may be treated via cheilectomy in which the metatarsal head is reshaped and bone spurs reduced.

Another example of MTP joint implant is "Roto-glide" which is designed to restore optimum anatomical movement whilst preserving as much primary bone stock as possible.
