Rigid internal fixation of the Mitchell-Hawkins osteotomy/bunionectomy with the Herbert Bone Screw

The author reports on his use of the Herbert Bone Screw to obtain rigid internal fixation of the Mitchell-Hawkins osteotomy-bunionectomy procedure (distal metatarsal osteotomy). A pilot drill with a built-in stop to prevent overpenetration is used first and then the screw can be inserted with jig, or it may be inserted manually if the osteotomy is stablized temporarily with a Kirschner wire. The screw is an excellent fixation device and does not have to be removed because it is made of inert materials and has no protrusive head.
