Abstract: We present a case series of patients with intradural spinal tumours who underwent posterior laminectomy followed by lamina reimplantation. This technique demonstrated favourable post-operative MRI visualisation and minimal adhesions. The primary objective of this study was to evaluate the potential benefits of lamina reimplantation following laminectomy in the surgical treatment of intradural spinal tumours. This was compared to conventional laminectomy techniques without reimplantation. A retrospective review of five patient cases was conducted, examining clinical notes and radiological imaging. Additionally, a literature review was performed to contextualise the findings within existing knowledge. Five patients with intradural spinal tumours underwent posterior laminectomy with lamina reimplantation. Post-operative MRI imaging showed excellent clarity, with minimal artefacts, enabling effective monitoring for residual or recurrent tumour. One patient developed tumour recurrence, necessitating reoperation. Notably, during re-exploration, there were no adhesions between the dura and reimplanted bone, significantly facilitating surgical access. The literature supports these observations, suggesting that lamina reimplantation may reduce postoperative spinal instability and epidural fibrosis, and it avoids the imaging artefacts commonly associated with metallic instrumentation. Lamina reimplantation after laminectomy in patients with intradural spinal tumours may offer significant advantages, including preservation of spinal stability, reduced scar tissue formation, and improved post-operative imaging. Further comparative studies on a larger scale are needed to substantiate these findings and guide best surgical practices.
