The GAIT Implant is designed for replacement of the first metatarsophalangeal joint. The GAIT MPJ prosthesis is constructed of medical grade silicone elastomer and is available in three sizes: small, medium and large, as well as individually color coded sizers. The GAIT spacer procedure is reserved for Class 3 type degeneration of the first metatarsophalangeal joint with narrowing of the joint space, loss of the joint cartilage, bony spurring surrounding the joint space and a painful range of motion of the first metatarsophalangeal joint, both with rotation and walking. The benefit of the surgery is to allow regular walking without the accompaniment of degenerative arthritic pain. This type of surgical correction is not expected to recreate a normal range of motion of the first metatarsophalangeal joint. The implant is meant to augment the Keller arthroplasty procedure by stabilizing the hallux to the first metatarsal head in the transverse, sagittal and frontal plane.
60/60 is the criterial for this implant:
- Over 60 years of age or less than 60% of normal push-off ability.
