Background & Importance: Spinal deformity is one of the most common disorders among the vertebral diseases that results from unnatural curvatures of spine, such as scoliosis and kyphosis. Spinal fusion surgery is used most commonly to treat certain types of spinal deformity. Herein, we reported the efficacy of posterior spinal fusion accompanied by instrumentation in patients with the limitations of the anterior approach. Case Presentation: This case series study included six patients. There were three cases of severe gibbus deformities, a case of kyphosis deformity and two cases of both kyphosis and scoliosis. Two cases of gibbus deformities had undergone spinal fusion with instrumentation, and relatively satisfactory correction was observed for both patients. One patient, who had been treated with posterior decompression and fixation, returned to leading his normal active life. One case of severe deformities had no dynamic problems four years after receiving the instrumentation surgery. Conclusion: The outcomes of posterior spinal fusion surgery were found to be satisfactory in patients with the limitations of the anterior approach.
