Abstract

Breakage of hardware is not an uncommon complication in spine surgery practice. Pedicle screw breakage is the commonest instrument failure encountered in spine surgery, and different relatively simple, techniques have been recommended to retrieve the threaded part of it. Per-operative breakage of an instrument like pedicle seeker and jaw of disc forceps is unpredictable and removal of an unthreaded smooth implant is difficult. We experienced breakage of the pedicle seeker while putting a pedicle screw in a case of spondylolisthesis and breakage of the mobile jaw of a disc forceps in another case of prolapsed intervertebral disc. Here we present an innovative technique of removal of the broken instrument through the pedicle. Regular maintenance and replacement of al old instrument is recommended.
