Introduction

Less invasive techniques have always been welcome for management of patients with ‘Metastatic Spinal Disorders’. This is because these patients can be poor candidates for extensive / major invasive surgery even though radiologically, there may be an indication for one. The aim of the treatment with Minimal Invasive Fixation (MIS) systems is mainly for ‘pain relief’ than to radically decrease tumour burden or to achieve near total spinal cord decompression, which could be major presentations in these patients. These procedures address the ‘spinal instability’ very well and they can address pain associated with compression fractures resulting from metastatic disease from a solid organ as well as multiple myeloma with minimal complications. These procedures can be combined with radiology and chemotherapy without much concern for wound problems in the way of infection or dehiscence. They also have a great advantage of timing of adjunct therapy closer to the index procedure. The disadvantage, however, are they do not allow thorough decompression of the spinal cord. There could also be problem in addressing patients who have severe vertebral height loss or loss of integrity of the anterior column where anterior column reconstruction may be required. There is a risk of inadequate fixation or implant loosening or failure. We aim to examine the results of MIS surgery in our department and support the rationale for its use.
