Background: The availability of intraoperative fluoroscopy and improved access to varieties of spinal titanium implants has revived posterior spinal stabilization techniques with their distinct advantages. Our aim is to describe the profile of various spine pathologies requiring subaxial posterior spinal decompression, stabilization (using titanium implants), and arthrodesis, and to determine the rate of postoperative complications and factors affecting outcome. Materials and Methods: This is a prospective single institution study of consecutive adult patients seen during the study period. Data collected included the patients' demographics, radiological findings, indication for surgery, surgical procedure, operation time, intraoperative blood loss, and postoperative complications. Results: There were 26 patients (15 males and 11 females). Their ages ranged between 24 and 78 years (median = 42 years). The most common indications for surgery were spinal trauma and degenerative spine disease (24 patients). The region that was most commonly stabilized was the lumbar- 12 cases (46.2%). No patients experienced neural or vascular injury as a result of screw position; likewise no patient had screw loosening. There was a case each of superficial surgical site infection and transient cerebrospinal fluid leak but no case of implant failure was encountered. The outcome was significantly associated with the etiology (0.030) of the indication for surgery and preoperative power grade (0.000). Conclusion: Spinal trauma and degenerative spine disease are the two most common indications for posterior spinal decompression, stabilization and fusion in our center. It is associated with acceptable postoperative complication rate when done under fluoroscopic guidance. Outcome is related more to the preoperative neurological deficit and etiology of the indication for surgical stabilization.
