The Vilex CHI Cannulated Metallic Hemi Implant, a hemi-arthroplasty implant for the metatarsophalangeal (MTP) joint, is indicated for use in the treatment of patients with degenerative and post-traumatic arthritis in the MTP joint in the presence of good bone stock and integrity of the phalangeal base, along with the following clinical conditions: Hallux Limitus, Hallux Valgus, Hallux Rigidus, and an unstable or painful MTP joint.
