Abstract
Background Data: Lumbar spondylolisthesis is a prevalent cause of lower back pain and is a focal interest of spinal surgery. A diverse set of decompression and fusion techniques are used in surgery.
 
 Purpose: To investigate the surgical and clinical outcomes patients with spondylolisthesis who received surgical intervention. 
 
 Materials and Methods: Data of 25 patients (15 women; 10 men; mean age, 48.8 ± 12.4 years; range, 27–66 years) with low-grade spondylolisthesis who received surgical intervention were retrospectively analyzed. Posterolateral and posterior interbody fusion was used in 17 and 8 patients, respectively, and 19 received posterior pedicle screws and 6 received only fusion and decompression. 
 Results: According to the Kirkaldy–Willis criteria, the clinical outcomes of 11 (44%), 9 (36%), 3 (12%), and 2 (8%) patients were rated excellent, good, fair, and poor, respectively, with a success rate of 80%. Furthermore, fusion was observed in 21 patients (84%). Favorable outcomes were achieved in 17 (90%) patients with pedicle screws and in 3 (50%) with only decompression and fusion (p=0.048; p0.05). Two out of three patients with revision surgery had poor clinical outcomes (p=0.091; p
