Study DesignRetrospective.ObjectiveAssess the outcomes of single stage posterior transpedicular corpectomy with cement-based anterior column support for spinal metastasis at longer follow-ups.Summary Of Background DataLife expectancy of cancer patients is constantly increasing. Reliable anterior column reconstruction after posterior corpectomy becomes necessary.MethodsIn this retrospective monocentric study, patients who underwent posterior transpedicular corpectomy and cement-based anterior reconstruction, with a minimum 6 months follow-up, were included. Ambulatory status and pain visual analog score(PVAS), complication rates and Local Sagittal Cobb angle (LSA) were evaluated preoperatively, postoperatively and at the latest follow-up.ResultsIn total, 253 patients were included, with a mean follow-up of 21 months [6-132] and a median survival of 9 months. Pre-operatively, 202 patients(81%) were ambulant while 47 patients (19%) weren't. At the latest follow-up, 241 patients (95%) were ambulant while 12 patients(5%) weren't (P<0.001). Dorsal/lumbar PVAS went from 8.2±2.2 pre-operatively to 5.2(±1.7) post-operatively reaching 3.4±1.9 at the latest follow-up (P<0.001). Mean LSA decreased from 13.2⁰(±5.78) pre-operatively to 6.11⁰(±8.51)(P<0.001) post-operatively and reached 7.56⁰(±7.55) at the latest follow-up(P=0.59). Complications occurred in 39(15.4%) patients. One-third of those were mechanical(rod/screw fracture, cement displacement) needing re-intervention in 4 patients(1.6%).ConclusionsThe mechanical stability offered by the cement-based anterior reconstruction is maintained during the lifespan of patients operated for the spinal metastasis. Satisfying functional and radiological outcomes observed at the last follow-up show that this lasting, cost sparing, and relatively simple reconstruction technique, is a valid alternative for the costly and more complicated cage-based reconstruction.Copyright © 2024 Wolters Kluwer Health, Inc.
