We retrospectively reviewed the records of 16 children treated for spondylodiscitis at our hospital between 2000 and 2007. The mean follow-up was 24 months (12 to 38). There was a mean delay in diagnosis in hospital of 25 days in the ten children aged less than 24 months. At presentation only five of the 16 children presented with localising signs and symptoms. Common presenting symptoms were a refusal to walk or sit in nine children, unexplained fever in six, irritability in five, and limping in four. Plain radiography showed changes in only seven children. The ESR was the most useful investigation when following the clinical course of the disease. Positive blood cultures were obtained in seven children with Staphylococcus aureus being isolated in five. Antibiotics were used in 14 children and spinal bracing in six. Children with spondylodiscitis often present with a confusing clinical picture leading to late diagnosis. The early use of MRI in the investigation of children with an atypical picture may avoid unnecessary delay in starting treatment and possibly prevent long-term problems. All except one of our children had made a complete clinical recovery at final follow-up. However, all six children in the > 24-month age group showed radiological evidence of degenerative changes which might cause problems in the future.

Introduction The aetiology of coccydynia can be multifactorial, with several associated factors such as obesity, female gender and low mood. The long-term results of operative interventions, such as manipulation under anaesthesia and coccygectomy are variable, ranging from 63-90%. Materials and methods Our aim was to identify whether age, trauma and body mass index (BMI) were independent prognostic factors in coccydynia treatment. All patients who presented to the Royal Derby Hospital with a primary diagnosis of coccydynia between January 2011 and January 2015 who had injections, manipulation under anaesthesia or coccygectomy were included. We used patient-reported satisfaction score as the primary outcome measure. We hypothesised that patients with preceding history of trauma and with high BMI (> 25) would be less satisfied. We divided patient BMI into four groups, following World Health Organization guidelines: group A (18.5-24.9), group B (25-29.9), group C (30-39.9) and group D (> 40). Results A total of 748 patients were diagnosed with coccydynia. Of these, 201 patients had 381 injections, 40 had 98 manipulations under anaesthesia and 9 had coccygectomy. Mean age was 46.4 years; 26% of patients had trauma to the coccyx. The mean time to follow-up was 7.3 months. We found a statistically significant difference (P = 0.03) between satisfaction scores in groups B and D. Patients who had trauma improved significantly (P = 0.04). The odds ratio calculation of coccygectomy and BMI revealed a higher risk of coccygectomy in Group A. Discussion This is the first study to establish BMI and trauma as independent prognostic factors for coccydynia treatment. Our hypothesis that patients with higher BMI would have lower satisfaction levels has been proven true.

Purpose Predicted survival of a patient is the most important parameter that helps to guide the treatment of a patient with metastatic spinal cancer. We aimed to investigate the reliability of modified Tokuhashi score in the decisionmaking process in patients with metastatic spinal cancer. Methods We performed a review of our prospectively collected Metastatic Cancer Database over a period of 4 years (2007)(2008)(2009)(2010). Ninety consecutive patients who were treated for metastatic spinal cancer were enrolled. Data review included demographic details, source of primary cancer, duration of symptoms, location of metastases, calculated Karnofsky's performance status, and calculated survival based on modified Tokuhashi score. We divided the patients into 3 groups. Group A included patients with expected survival less than 6 months. Group B included patients with expected survival between 6 and 12 months. Group C included patients whose expected survival was more than 12 months. We compared the calculated expected survival to the actual survival in all three groups with all patients following up to a minimum of 1 year or until death. Statistical analysis was done by Chi-square test and the Fisher Exact test.Results The survival prediction in group C was significantly accurate in 80.9 % patients (P = 0.027). However, in groups A and B, only 36.1 and 9.1 % patients survived, respectively, as per predicted. (P [ 0.05). Conclusions We can conclude from this study that, when used alone, modified Tokuhashi score may not be a reliable tool to predict survival in all patient groups.

INTRODUCTION Management of metastatic spinal disease has changed significantly over the last few years. Different prognostic scores are used in clinical practice for predicting survival. The aim of this study was to assess the accuracy of prognostic scores and the role of delayed presentation in predicting the outcome in patients with metastatic spine disease. METHODS Retrospectively, four years of data were collected (2007)(2008)(2009)(2010). Medical records review included type of tumour, duration of symptoms, expected survival and functional status. The Karnofsky performance score was used for functional assessment. Modified Tokuhashi and Tomita scores were used for survival prediction. RESULTS A total of 55 patients who underwent surgical stabilisation were reviewed. The mean age was 63 years (range: 32-87 years). The main primary sources of tumours included myeloma, breast cancer, lymphoma, lung cancer, renal cell cancer and prostate cancer. Of the cases studied, 29 patients had posterior instrumented stabilisation alone, 10 patients had an anterior procedure alone and 16 patients (with an expected survival of more than one year) had both anterior and posterior procedures performed. Twenty-three patients presented with spinal cord compression. The mean follow-up duration was 9 months (range: 1-39 months). Patients who were treated within one week of referral survived longer than anticipated. Patients were divided into three groups based on their expected survival. Actual survival was better in all three groups after surgery. Discrepancies in scores were prominent in patients with myeloma, breast and prostate cancers. Functional outcome was better in patients under 65 years of age. CONCLUSIONS The prognostic scoring systems are not uniformly effective in all types of primary tumours. However, they are useful in decision making for surgical intervention, taking other factors into account, in particular the age of the patient, the type and stage of the primary tumour and general health.
