Aims and Objectives :To provide an initial experience in performing the procedure of the use of pedicle screws and rods for stabilisation of the spinal column in Nigerians with highlights on indications and outcome of surgery. Materials and Methods: The hospital records of all the patients who had the procedure were retrieved. Biodata, presentation, neuroimaging findings, surgical procedure and postoperative outcomewere extracted from records. Evidence of recurrent spinal instability, change in neurological status, wound infection and implant related complications postoperatively were used as outcome measures Results: Twenty seven procedures were performed in 26 patients [male: female was 1:1]. The age range was 26 to 77 years (mean=52.9, SD= 13.7). Seventeen (65.4%) patients had degenerative spinal disease, while 9 (34.6%) had trauma. Five patients (19.2%) had thoracic spinal lesions and these were secondary to trauma, while there were 21 (80.8%) patients with lumbar spinal lesions. The indications for surgery were spinal instability in trauma cases and/or anticipated instability for degenerative cases. Two spinal segments were fused during 11 (40.7%) procedures, 3 in 10 (37.4%), 4 in 4 (14.8%) and 5 segments in 2 (7.4%) procedures. Post operatively, the Frankel grading improved in 6 (23.1%) patients, while it remained the same in 20 (76.9%). Back pain resolved in all but 1 (96.2%) patient. One (3.9%) patient each had screw fracture, recurrent instability andsymptomatic redundant rod lengthwhile 2 (7.7%) peri-operative mortalities occurred due to cardiac events. Conclusion: The most common indication for posterior spinal stabilisation with pedicle screws and rods in this study is established or anticipated instability from degenerative lumbar spinal disease.Immediate stabilisation was achieved in majority of the patients without postoperative neurological deterioration.
