title: [Analysis of complication in the spinal pedicle screw internal fixation].
abstract: In 1990-1998, five hundred and twenty patients treated with spinal pedicle screw internal fixation were analyzed. The main operative complication was screw misplacement(7.1%), and others such as screw bend and extra-long screw were less seen. The postoperative complications included screw breakage (13.3%) and backache(14.2%). Recently, by making use of RF screw system and X-ray monitor, the complications were significantly decreased.
