- W4243473328 abstract "Abstract Background: There have been several reports of instrumentation failure after 3-column resections such as total en bloc spondylectomy (TES) for spinal tumours; nevertheless, clinical outcomes of revision surgery for instrumentation failure after TES are seldom reported. Therefore, this study assessed the clinical outcomes of revision surgery for instrumentation failure after TES. Methods: This study employed a retrospective case series in a single centre and included 61 patients with spinal tumours who underwent TES between 2010 and 2015 and followed for >2 years. Instrumentation failure rate, back pain, neurological deterioration, ambulatory status, operation time, blood loss, complications, bone fusion after revision surgery, and re-instrumentation failure were assessed. Data were collected on back pain, neurological deterioration, ambulatory status, and management for patients with instrumentation failure, and we documented radiological bone fusion and re-instrumentation failure in cases followed for >2 years after revision surgery. Results: Of the 61 patients, 26 (42.6%) experienced instrumentation failure at an average of 32 (range, 11−92) months after TES. Of these, 23 underwent revision surgery. The average operation time and intraoperative blood loss were 204 min and 97 ml, respectively. Including the six patients who were unable to walk after instrumentation failure, all patients were able to walk after revision surgery. Perioperative complications of reoperation were surgical site infection (n = 2) and delayed wound healing (n = 1). At the final follow-up, bone fusion was observed in all patients. No re-instrumentation failure was recorded. Conclusion: Bone fusion was achieved by revision surgery using the posterior approach alone." @default.
