Abstract
A fully implantable, incrementally adjustable osteotomy fixation apparatus is disclosed. The apparatus comprises a first plate member, and a second plate member being telescopically received within the first plate member. The osteotomy fixation apparatus may further comprise a ratchet assembly, operatively associated with the first and second plate member, which allows for advancement of the first plate member relative to the second plate member, but prevents retraction. Attachment means operatively associated with the first and second plate members are provided for attaching the apparatus to the bone. The apparatus may also include an external extension brace, operatively associated with the ratchet, for extending the second plate member relative to the first plate member so that post-operative angular correction of the bone may be achieved. A method of performing an osteotomy to the bone is also disclosed utilizing the fixation apparatus herein disclosed.
