INTRODUCTION: Osteotomy procedure is an effective tool for the correction of fixed sagittal plane deformity. However, there is potentially significant perioperative morbidity associated with this technique in adults and was known to have some complications including but not limited to increased blood loss and surgical time.

METHODS: Retrospective study with a minimum of 2 years follow‐up between 2002 and 2006. 15 patients were included in the study.9 patients underwent PSO were included in the first group, and 6 patients underwent SPO were included in the second group.The mean age PSO group was 48 years and 42 in SPO group.Eight of the patients had undergone at least one previous spine surgery in the region of the PSO, and nine of them had comorbidities that increased their surgical risk. We identified all causes of perioperative morbidity. Radiological results including standing long‐film of the spine were obtained and measurements were made preoperative, postoperative, and at most recent follow‐up.

RESULTS: The mean follow‐up was 28 months. The mean operation time in PSO group was 260 min. and 185 min. for SPO group. The mean blood loss in PSO group 850 mL. and 400 mL. for SPO group. In PSO group, we had 3 patients, 33%, who developed spinal infection at the site of surgical osteotomy and 1 patient developed temporary weakness of his Right TBA, this completely resolved after 9 months. In the SPO group,2 patients had complications, 1 deep infection not resolved with all measures and the other died on the second postoperative day.

DISCUSSION: Spinal Osteotomy procedures had a significant risk for infections and we found no statistical significance between these two types of osteotomies as regards infection, implant failure, blood loss and surgical time. Obese patients and bad general conditions as cardiac, hepatitis and diabetic patients had a significant increase of risk for major spinal complications.
