Patient reported outcome measures (PROMs) and psychological aspects of spinal conditions play an important role in its management. Disability benefit in the social welfare system is being closely scrutinized. The PHQ9 and GAD7 are used widely in general practice to aid assessment of depression and anxiety/somatization. To date, their use in the spinal surgery out patient setting has not been assessed. Over a one-year period the senior author saw 516 new patients. Each patient completed a standard spinal assessment questionnaire consisting of several demographic/aetiological questions and PROMs (VAS back, VAS leg, ODI/NDI, PHQ9 and GAD7). An analysis of these scores was performed.Introduction
Materials and Method
To determine whether measuring pedicle size on CT is accurate and reproducible using the WEBPACS ruler tool Radiological analysis. A human cadaveric spine along with 5 geometrical shapes were scanned using a multislice spiral CT scanner with 1mm cuts. The objects and the pedicle diameters for lumbar and thoracic vertebrae in the axial plane were measured independently using the WEBPACS ruler tool by 2 observers (to the nearest 0.1mm). The geometrical shapes and pedicle size on the skeleton were then measured using Vernier callipers by an independent third observer. All measurements were repeated a week later. Reproducibility of the measurements was assessed using Bland and Altman plots. Accuracy was assessed using the Vernier calliper measurements as the gold standard and comparing the plots. Perfect reproducibility was achieved when measuring the geometric objects with the Vernier callipers. The error of the measurement associated when measuring the pedicles was 0.5mm. The error of the measurement for the geometric objects for observers 1 and 2 was 0.5 and 0.6mm respectively, and for the pedicles it was 1.0 and 0.6mm respectively. The WEBPACS ruler on a CT scan is accurate to within 0.5-0.6mm of the true size of an object. The error for pedicle measurements is marginally higher (0.6-1.0mm) and this may reflect the fact that they are ill defined geometric shapes. Measuring pedicle size on CT for surgical planning may have implications for small pedicles when sizing them up for a good screw. Ethics approval None Interest Statement None
Peninsula Spinal Unit, Princess Elizabeth Orthopaedic Centre, Royal Devon and Exeter Foundation NHS Trust, Exeter, UK. A retrospective audit in 2000 of cases presenting with metastatic cord compression (MSCC) was conducted. In June 2009 we introduced the role of MSCC coordinator. We present the preliminary results from a 6 month comparative audit and discuss whether implementation of the NICE Guidelines have improved the care pathway. Prospective cohort study with retrospective controlled group. Adults with suspected MSCC Length of time to MR imaging % referred for surgical opinion Length of time on bed rest. % undergoing surgery Retrospective audit 2000 38 cases confirmed MSCC. 11 did not have MRI and were treated on the basis of clinical symptoms. Average time from admission to MRI 42 hours. 8 patients (21%) referred for surgical opinion. None had surgery 38 had radiotherapy. Spinal stability documented on 1 patient. 5.5 days average bed rest Prospective audit 2009 54 patients referred to co-ordinator as suspected MSCC. 52 had MRI and 2 had CT. Average time from referral to MRI 41 hours. Average time for patients with neurological deficit 7.6 hours. 54 patients (100%) referred for surgical opinion. 12 patients had surgery (22%). 100% patients had spinal stability documented. Average length of time on bed rest 2 days. It is uncertain whether these results are attributed to the introduction of the NICE guidelines or improved awareness of condition. However we feel that NICE guidelines have improved the care pathway of patients with MSCC. Statement of ethics and interests: Study was approved and registered with audit department.
