PurposeThe aim of the current study is to analyze perioperative data and complications of open vs. percutaneous dorsal instrumentation after dorsal stabilization in patients suffering from fractures of the thoracic or lumbar spine.MethodsIn the time period from 01/2007 to 06/2009, open surgical approach was used for dorsal stabilization. The percutaneous surgical approach was used from 05/2009 to 03/2014. In every time period, all types of fractures were treated only by open or by percutaneous approach, respectively, to avoid any selection bias. Retrospectively, epidemiological data, complications and perioperative data were documented and statistically analyzed.ResultsA total of 491 patients met the inclusion criteria. Open surgery procedure was carried out on 169 patients, and percutaneous surgery procedure was carried out on 322 patients. Fracture level ranged from T1 to L5, and fractures were classified types A, B, and C. In 91.4% of all patients, no complication occured following dorsal stabilization after traumatic spine fracture during their hospital stay. However, 42 complications related to dorsal stabilization have been documented during the hospital stay. The complication rate was 14.8% if open surgical approach has been used and was significantly reduced to 5.3% using percutaneous surgical approach. Post-operative hospital stay was also reduced significantly using the percutaneous surgical approach.ConclusionsAccording to the current study, percutaneous dorsal stabilization of the spine could also be safely used in trauma cases and is not restricted to degenerative spinal surgery.
