[Correction of neurological complications after transpedicular stabilization of the spine].
Nowadays transpedicular fixation systems have gained great priority in stabilization of thoracic and lumbar spine. But implantation of the system may cause iatrogenic complications due to extrapedicular insertion (malposition) of screws. Present work is devoted to analysis of neurologic disturbances of screw malposition in the prospective study of 44 consecutive patients. Patients had complains which could be attributed to mistakes in implantation of TPF system. After detailed examination we created a group of 8 patients who had compression of spinal cord and radices due to inadequately implanted TPF system (5 male and 3 female patients, age range 27-63 (median 42)). According to malposition of screws we divided patients into 3 groups: medial malposition (3 patients); lateral (2 patients); and 2 patients with inferior-lateral malposition. 1 patient had both medial and lateral malposition of screws. On the basis of results of treatment we suggested management protocol for complications due to mistakes in implantation of TPF.
