Postoperative CT image of the patient with decreased muscle strength in the traditional fluoroscopy group
A patient with cervical malignancy underwent cervical spine tumor resection and pedicle screw fixation manually to implant pedicle screws at C4 and C5. Postoperative CT showed a 4.74 mm breach of the cortical bone at the right CPS and a 2.65 mm breach of the cortical bone at the left CPS of C4 vertebra. Neo scales of both sides of C5 were Grade 0. The patient presented with a decreased grip strength in the left hand, and refused to undergo a second operation. After 2 months of rehabilitation treatment, the patient’s left hand-grip strength was recovered from level 2 to level 4
