Abstract
The aim of this study was to prospectively assess the outcome of patients with metastatic spinal disease who underwent minimally invasive fixation of the spine for intractable pain or spinal instability.
This is a prospective audit of patients with metastatic spinal cord disease who have undergone minimally invasive fixation of the spine from August 2009 until the present date. This was assessed by pre and post-operative Oswestry Disability Index (ODI), EQ5D and Tokuhashi scores. Intra- and post-operative complications, time to theatre, length of inpatient stay, analgesia requirements, mobility, chest drain requirement and post-operative HDU and ITU stays were also recorded.
So far, 10 patients have met the criteria. There were no intra-operative complications. Post-operatively, there were no complications, chest drains, increase in analgesia or stay on the HDU or ITU. All patients showed an improvement in mobility. The mean post-operative day of mobilisation was 2 days, post-operative days until discharge 5.3 days and length of inpatient stay was shorter than traditional surgery. Blood loss was minimum except one patient with metastatic renal cell carcinoma who needed transfusion intraoperatively.
ODI, VAS and EQ-5D scores were calculated and were significantly improved compared to preoperatively.
This novel approach to management of metastatic spinal disease has resulted in improved mobility, short inpatient stays without the need for chest drains, HDU or ITU and an improved the quality of life in pallliative patients. This is a completely new strategy to treat the pain in these patients without the usual associated risks of surgery and has major advantages over traditional surgical techniques which may preclude this group of patients having any surgical stabilisation procedure at all
