Background: Minimally invasive techniques in spinal surgery are increasing popularity as it reducing length of stay, morbidity risk, post-operative analgesia and early return to work. Objective: A prospective study to evaluate the clinical outcome of percutaneous fixation for disabling low back pain associated with lumbosacral GI spondylolisthesis. Methods: Twenty patients with 1st degree lumbar spondylolisthesis underwent percutaneous fixation after failure of at least 6 months of conservative treatment. All patients with neurological compromise and requiring decompression or had previous spine surgery were excluded. There were 16 males (80%) and four female (20%). Patient’s age ranged from 30 to 42 years old with average age 37 years old. Clinical outcome was evaluated by Japanese Orthopedic Association Score (JAOS). Operative time, blood loss, and postoperative pain were also recorded. Results: Average follow up periods were 15.5 months. According to JOAS mean preoperative score was 18, which are improved to mean 27.85. Overall results were excellent mean improvement rate were 89.76%. Mean operative time 96 minutes; mean blood loss was 100 mL. Postoperative X-Ray has proper screws position. The complications occurred in two cases (10%) and dealt with them accordingly. Conclusion: Percutaneous fixation for management of symptomatic 1st lumbosacral spondylolisthesis allows for safe and efficient minimally invasive procedure had good clinical results. Further prospective studies with long-term follow-up results are required to assess the definitive merits of percutaneous instrumentation of the lumbar spine.
