2009 – Outcomes and complications of extension of previous long fusion to the sacro pelvis: does surgical approach make a difference?

Summary: Multicenter, retrospective review of outcomes following extension of previous long scoliosis fusions to the sacro-pelvis demonstrated that posterior only procedures (PSF) had similar sagittal correction and fewer complications at 2 year follow-up than combined anterior-posterior procedures (APSF).

2009 – Extension of previous fusions to the Sacro-Pelvis vs. Primary spino-pelvic fusions in the setting of adult deformity: A comparison of health related quality of life measures and complications

Summary: Clinical and radiographic evaluation of revision extension of previous long thoracolumbar fusion to the sacro-pelvis compared to primary lumbosacral fusion indicates that although the two patient populations are heterogeneous, clinical outcomes and complication rates of salvage procedures where a prior spinal fusion procedure is extended to the sacro-pelvis compare favorably to primary sacro-pelvic fusion for adult spinal deformity.

2009 – PSO failures can be predicted by high pre-op SVA and Pelvic Tilt

Summary: PSO technique has been reported as a method to obtain significant sagittal re-alignment, although sub-optimal results may still occur. This retrospective multi-center study on patients who underwent a lumbar PSO, suggested that failed post-operative alignment can be predicted and that a PSO alone for marked sagittal mal-alignment may be insufficient to obtain acceptable radiographic outcome.

2009 – Pre-operative pelvic parameters must be considered to achieve adequate sagittal balance after lumbar osteotomy

Summary: PSO procedure is now commonly used for realignment of patients with marked sagittal mal-alignment. It is also commonly accepted that patients with different sagittal deformities will require different surgical procedures. This study focuses on patients with large pre-operative imbalance and aims to identify the key parameters that lead to successful post-operative alignments based on pre-operative sagittal spino-pelvic parameters. This study demonstrated that patients with large pre-operative pelvic tilt required a larger PSO resection of reach an acceptable post-operative alignment

2009 – Patients Perceive Perioperative Complications as More Severe and Having Greater Negative Consequences than Surgeons

Summary: Survey of patient and surgeon perceptions of different perioperative complications associated with spinal deformity surgery demonstrated patients perceive complications more severe and more negatively impacting satisfaction and quality of life than surgeons. Dural tear and blood transfusion demonstrated the greatest discrepancy between patient and surgeon perceptions. These results demonstrate a potential need for improved patient education and surgeon communication, and will be used to further develop an adverse event impact instrument.

2009 – The impact of reciprocal regional alignment of changes distant from the site of spinal osteotomies affects post operative spinal balance

Summary: Large vertebral resections are more frequently utilized in the setting of sagittal malalignment. If the effect of such a resection on regional alignment can be predicted, its impacts on distant unfused levels still need to be understood as they relate to the final post-operative alignment. Data from this study suggests that a lumbar and thoracic resection/osteotomy will impact the unfused reciprocal levels and respectively increase the thoracic and lumbar regional curvature of the unfused segments.

2009 – Major Complications Following Adult Spinal Deformity Surgery: Is There a High Risk Patient Profile?

Summary: Perioperative complications are a major consideration in Adult Spinal Deformity. This retrospective consecutive multicenter study established patient profile of subjects with major peri-operative complication. Results revealed that patient profiles may not be ‘typical’ of high risk patients. Future prospective studies will use this information to develop a risk scoring system (RS3) for Adult Spinal Deformity patients.
