Low back pain is a common complaint, affecting up to one third of the adult population costing over £1 billion to the NHS each year and £3.5 billion to the UK economy in lost production. The demand for spinal injections is increasing allowing for advanced spinal physiotherapists to perform the procedure. The objective of this study was to investigate outcome following spinal injections performed by consultant spinal surgeon (n=40) and advanced spinal physiotherapists (ASP) (n=40) at our centre. Data on 80 patients who had received caudal epidural (n=36), nerve root block (n=28) and facet joint injections (n=16) form August 2010 to October 2011 consented to be in the study. 40 patients in each group completed Oswestry Disability Index (ODI), Visual Analogue Scores (VAS) before and 6 weeks after the procedure and patient satisfaction questionnaire investigating their experience and any complications related to the spinal injection retrospectively. The study included 32 males and 48 females. Mean age 57 years, range 21–88. [Consultant group M:17, F:23 mean age: 55, range 21–81. ASP group M:15, F:25 mean age 59, range 22–88]. Measures of patient satisfaction and outcome were obtained; using 2 tailed independent samples Introduction and aims
Method and Materials
The effect of head injury on systemic physiology, including bone healing is still a topic of vivid discussion. We aimed to investigate whether in patients with long bone fractures the presence of head injury is associated with excessive callus formation. Data on patients with head injury and femoral diaphyseal fracture admitted to our trauma unit between 1997- 2002 were collected and analysed. Patients with factors that could influence bone healing such as smoking, NSAIDs and hormonal disorders were excluded. The severity of head injury was quantified using GCS, AIS and CT scan reports. Patients matched for age, sex and ISS with femoral shaft fractures and no head injury formed the control group of the study. All the fractures were stabilised with reamed femoral nail. The quantification of fracture healing response was estimated by taking the radiological ratio of the largest diameter of callus formed into two planes and the adjacent normal diameter of femoral canal. The minimum follow-up of the patients was 12 months. In total 42 patients were studied, 17 with head injury and femoral fracture and 25 with an isolated femoral fracture, (control group). Both groups were comparable in terms of age, sex, ISS. The difference between the mean callus to diaphyseal ratio was statistically significant for both the AP and Lateral projections (AP – mean difference 0.462, 95% CI 0.312 to 0.602, p<0.0001, LAT – mean difference 0.289, 95% CI 0.142 to 0.436, p<0.001) with the head injured patients having more florid callus compared to the control group. This study supports the view that head injury leads to exuberant callus formation in patients with long bone fractures. The mechanisms of this response could be both central and local. Research is ongoing to elucidate the pathways involved in this biological phenomenon.
