Introduction

Traditionally complex spinal surgery in Belfast has been performed at the Royal Victoria Hospital (RVH). Since an amalgamation the RVH has become effectively the level 1 trauma centre for the province. The ever increasing complexity of spinal surgery in addition to changes in practice such as the management of metastatic spinal cord, are placing significant demands on the service. At a time when resources are scarce trends in patient profiles are highly important to allow adequate planning of our service.

Aim

To establish trends in patient profiles in a level one trauma centre also managing spinal pathology over the last 10 years and to examine the impact of this on our service.

Background

The incidence of scoliosis is 2/1000 population in the UK with 80% being idiopathic. In the Royal Victoria Hospital, Belfast there are approximately 25 scoliosis operations per year, the majority are for idiopathic causes and are limited to posterior instrumentation and fusion. It is current practice in this hospital to use a cell salvage machine for every case managed by nursing staff.

Objective

To ascertain the requirement for and the economical viability of cell salvage during posterior instrumented scoliosis surgery.

Stable thoracolumbar fracture is a common injury. The factors that determine its outcome are unclear. Aspects of injury severity were analysed for their ability to predict outcome by controlling other outcome-affecting factors (patient's pre-injury health status, legal aspects, associated injuries, etc.). No reliable disc injury severity grading system was available and therefore a new system was developed.

A prospective observational study of 44 conservatively treated patients with stable fractures between T11 and L5 was conducted. Bony injury severity was scored based on comminution, apposition and kyphosis parameters. Disc injury severity was scored by the new scale based on variables – Herniation, Indentation, Height decrease and Signal change – seen in MRI. Ten outcome domains (five domains of pain and function each) were assessed at 1 to 2 years from injury. The data was analysed by non-parametric correlation and stepwise-linear regression analysis to assess the predictive value of different variables (patient factors, injury factors and social factor) to outcome.

The correlation coefficients between injury severity and outcome were consistently higher with disc injury severity than bony. Disc injury severity showed highest predictive value for both pain (29%) and functional (16%) outcomes, whereas the bony injury severity parameters (kyphosis, etc.) and the posterior ligament injury severity provided no prediction of outcome. According to AO classification, the fractures were A1, A2, A3 and B1; in this spectrum of injuries, the AO classification had no prediction of outcome. The disc injury score also had a good predictive value for final disc degeneration.

Disc injury severity should be gauged in advising prognosis and treatment. The new disc injury severity grading system showed good construct validity.
