Objectives. Sacroiliac joint dysfunction is a degenerative condition that can result in low back pain and is likely underdiagnosed. Diagnosis is made clinically with the patient experiencing pain in the sacroiliac joint region. Initial management is non-operative with pain management, physiotherapy, injections, and rhizolysis. If these fail then surgical management, by sacroiliac joint fusion, can be considered. The aim of this study was to review the outcomes of all patients who underwent sacroiliac joint fusion by a single surgeon in a large district general hospital between April 2018 and April 2023. Design and Methods. A retrospective review of all patients who underwent sacroiliac joint fusion between April 2018 and April 2023 was conducted. Data was collected from clinical letters, operative notes, and the British Spinal Registry. Oswestry Disability Index (ODI) and Visual Analogue Scale (VAS) for back and leg pain were recorded as well as any post-operative complications. Results. In total 19 patients underwent sacroiliac joint fusion. Mean age was 47 years (range 27 – 69 years). Nine were right sided procedures and ten were left. The mean BMI was 32.3. ODI improved from a mean of 55 pre-operative to 26 at one year and 15 at two years post-operative. VAS for back pain improved from a mean of six pre-operative to three at one year and one at two years post-operative. VAS for leg pain improved from a mean of five pre-operative to four at one year and zero at two years post-operative. There were no surgical site complications. One patient developed trochanteric bursitis post-operatively. Two patients have since undergone sacroiliac joint fusion on the contralateral side with a further patient awaiting contralateral surgery. Conclusion. In patients with sacroiliac joint pain where non-operative measures have failed to control symptoms sacroiliac joint fusion is a reliable and effective surgical option

Aims. To compare the efficacy of decompression alone (DA) with i) decompression and fusion (DF) and ii) interspinous process device (IPD) in the treatment of lumbar stenosis with degenerative spondylolisthesis. Outcomes of interest were both patient-reported measures of postoperative pain and function, as well as the perioperative measures of blood loss, operation duration, hospital stay, and reoperation. Methods. Data were obtained from electronic searches of five online databases. Included studies were limited to randomised-controlled trials (RCTs) which compared DA with DF or IPD using patient-reported outcomes such as the Oswestry Disability Index (ODI) and Zurich Claudication Questionnaire (ZCQ), or perioperative data. Patient-reported data were reported as part of the systematic review, while meta-analyses were conducted for perioperative outcomes in MATLAB using the DerSimonian and Laird random-effects model. Forest plots were generated for visual interpretation, while heterogeneity was assessed using the I. 2. -statistic. Results. A total of 13 articles met the eligibility criteria. Of these, eight compared DA with DF and six studies compared DA with IPD. Patient-rated outcomes reported included the ODI and ZCQ, with mixed results for both types of comparisons. Overall, there were few statistically significant and no clinically significant differences in patient-rated outcomes. Study quality varied greatly across the included articles. Meta-analysis of perioperative outcomes revealed DF to result in greater blood loss than DA (MD = 406.74 ml); longer operation duration (MD = 108.91 min); and longer postoperative stay in hospital (MD = 2.84 days). Use of IPD in comparison to DA led to slightly reduced operation times (MD = –25.18 min), but a greater risk of reoperation compared to DA (RR = 2.70). Conclusion. Currently there is no evidence for the use of DF or IPD over DA in both patient-rated and perioperative outcomes. Indeed, both procedures can potentially lead to greater cost and risk of complications, and therefore, a stronger evidence base for their use should be established before they are promoted as routine options in patients with degenerative spondylolisthesis

Abstract. Objective. Flexible stabilisation has been utilised to maintain spinal mobility in patients with early-stage lumbar spinal stenosis (LSS). Previous literature has not yet established any non-fusion solution as a viable treatment option for patients with severe posterior degeneration of the lumbar spine. This feasibility study evaluates the mean five-year outcomes of patients treated with the TOPS (Total Posterior Spine System) facet replacement system in the surgical management of lumbar spinal stenosis and degenerative spondylolisthesis. Methods. Ten patients (2 males, 8 females, mean age 59.6) were enrolled into a non-randomised prospective clinical study. Patients were evaluated with standing AP, lateral, flexion and extension radiographs and MRI scans, back and leg pain visual analog scale (VAS) scores, Oswestry Disability Index (ODI), Zurich Claudication Questionnaire (ZCQ) and the SF-36 questionnaires, preoperatively, 6 months, one year, two years and latest follow-up at a mean of five years postoperatively (range 55–74 months). Flexion and extension standing lumbar spine radiographs were obtained at 2 years to assess range of motion (ROM) at the stabilised segment. Results. The clinical outcome scores for the cohort improved significantly across all scoring systems. Radiographs at 2 years did not reveal any loss of position or loosening of metal work. There were two incidental durotomies and no failures at 5 years with no patient requiring revision surgery. Conclusions. The TOPS implant maintains clinical improvement and motion in the surgical management of LSS and spondylolisthesis, indicating it can be considered an option for these indications

Up to one-third of patients experience limited benefit following surgical intervention for LS-OA. Thus, identifying contributing factors to this is important. People with OA often have multijoint involvement, yet this has received limited attention in this population. We documented the occurrence and evaluated the influence of multijoint symptoms on outcome following surgery for LS-OA. 141 patients undergoing decompression surgery+/−fusion for LS-OA completed the Oswestry Disability Index (ODI) pre- and 12-months post-surgery. Also captured pre-surgery: age, sex, education, BMI, smoking, depressive symptoms and comorbidities. Any joints with “pain/stiffness/swelling most days of the month” were indicated on a homunculus. A symptomatic joint site count (e.g. one/both knees= one site), excluding the back, was derived (range zero to nine) and considered as a predictor of magnitude of ODI change, and likelihood of achieving minimally clinically important improvement in ODI (MCID=12.8) using multivariable adjusted linear and log-Poisson regression analyses. Mean age: 66 years (range:42–90), 46% female. 76% reported one+ joint site other than the back, 43% reported three+, and nearly 10% reported six+. (< MCID) for those with three sites, and four units for those with six+ sites. Associated with a greater likelihood of not achieving MCID were increasing joint count (11% increase per site (p=0.012)), higher BMI, current/former smoker, and worse baseline ODI tertile. Results suggest there is more than just the back to consider to understand patient-reported back outcomes. Multijoint symptoms directly contribute to disability, but there is potential they may contribute to systemic, largely inflammatory, effects in OA as well

Advanced osteoarthritis of knee is associated with low-backache in a significant number of patients and adversely affects the quality of life. There is a paucity of literature describing outcomes of backache after total-knee-arthroplasty (TKA). We evaluated backache in patients of advanced knee-osteoarthritis and their functional and radiological outcomes after TKA after approval from Institutional ethics committee. Fifty-nine patients (40 females and 19 males) were included. Mean body-mass index was 28.7. Mean visual analogue score (VAS) for knee-pain was 7.98 preoperatively and 1.6 in follow-up. For chronic backache, the mean VAS score improved from 6.08 to 2.4, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) improved from 67.5 to 37.8, Knee society score (KSS) from 49.8 to 76.6, Oswestry Disability Index (ODI) Score from 55.44 to 34.65 and SF-36 Quality-of-life score from 44.95 to 74.63. There was a significant correlation between in knee and low-back functional scores. Magnetic resonance imaging-based scoring of degenerative changes (Pfirrmann grading) showed improvement only in 13.5% patients; 56% showed no change and 30.5% showed deterioration of scores. Chronic low backache is a significant co-morbidity in advanced knee-osteoarthritis. TKA has the potential to relieve backache along with knee-pain and improves quality of life

Seniors make up 16.9 percent of the Canadian population. Furthermore, the number of Canadians who are 65 years or older is increasing at an average rate of 20 percent every 5 years. In 2017, Sing etal reported that there is an increasing number of patients undergoing degenerative scoliosis surgery with the largest increase attributed to patients aged 65–69 years followed by those aged 70–74 years. Therefore, the purpose of this study is to assess the effectiveness of undergoing spinal surgery to correct degenerative spinal scoliosis in the ever-growing number of elderly patients. We hypothesize that age is not an independent prognostic factor of patients' outcomes followings degenerative scoliosis surgery. A retrospective review of prospectively collected data within the Canadian Spine Outcome and Research Network (CSORN) was conducted. Data was analyzed using IBM-SPSS. ANOVA was used to analyze continuous variables while Chi Square test was used to analyze categorical variables. Significance level was p < 0.05. There were 165 patients identified from the registry who met the inclusion criteria, 94 patients (57 %) were female. There were 102 (61.8 %) patients who were 65 years or older. The overall average age was 66.6 years (range 35–84, SD 8.6). There were 27 intra-operative complications, 44 peri-operative complications and 18 post operative complications. There was no statistically significant difference between the two age groups with regards to risk of developing intra-operative, perioperative and post operative complications. Patients who underwent degenerative scoliosis surgery reported an average improvement of 2.95±3.32, 3.64±3.50, 16.84±20.44 points on the back-pain scale, leg pain scale and the Oswestry Disability Index (ODI) respectively, there was no statistically significant differences in these measures between the two age groups. As the number of patients undergoing degenerative scoliosis surgery increases, clinicians will need to determine which factors will significantly impact patients' outcomes following surgery. This study shows that age is not an independent prognostic factor when it comes to patients' outcomes following degenerative scoliosis surgery. In the future, research should examine the impact of age in conjunction with factors such as frailty, comorbidities and functional status on patient outcomes

To investigate the effectiveness of surgical fusion for chronic low back pain (CLBP) compared to non-surgical intervention, databases were searched from 1966-2005. The meta-analysis was based on the mean difference in Oswestry Disability Index (ODI) change from baseline to follow-up. Four studies were eligible (634 patients). The pooled mean difference in ODI was 4.13 in favour of surgery (95% CI: -0.82-9.08; p=0.10; I2=44.4%). Surgery was associated with a 16% pooled rate of complication (95% CI: 12-20%, I2=0%). The cumulative evidence does not support surgical fusion for CLBP due to the marginal improvement in ODI which is of minimal clinical importance

INTRODUCTION. Lumbar total disc replacement (TDR) is an alternative treatment to avoid fusion related adverse events, specifically adjacent segment disease. New generation of elastomeric non-articulating devices have been developed to more effectively replicate the shock absorption and flexural stiffness of native disc. This study reports 5 years clinical and radiographic outcomes, range of motion and position of the center of rotation after a viscoelastic TDR. Material and methods. This prospective observational cohort study included 61 consecutive patients with monosegmental TDR. We selected patients with intermediate functional activity according to Baecke score. Hybrid constructs had been excluded. Only cases with complete clinical and radiological follow-up at 3, 6, 12, 24 and 60 months were included. Mean age at the time of surgery was 42.8 +7.7 years-old (27–60) and mean BMI was 24.2 kg/m² +3.4 (18–33). TDR level was L5-S1 in 39 cases and L4-L5 in 22 cases. The clinical evaluation was based on Visual Analog Scale (VAS) for pain, Oswestry Disability Index (ODI) score, Short Form-36 (SF36) including physical component summary (PCS) and mental component summary (MCS) and General Health Questionnaire GHQ28. The radiological outcomes were range of motion and position of the center of rotation at the index and the adjacent levels and the adjacent disc height changes. Results. There was a significant improvement in VAS (3.3±2.5 versus 6.6±1.7, p<0.001), in ODI (20±17.9 versus 51.2±14.6, p<0.001), GHQ28 (52.6±15.5 versus 64.2±15.6, p<0.001), SF 36 PCS (58.8±4.8 versus 32.4±3.4, p<0.001) and SF 36 MCS(60.7±6 versus 42.3±3.4, p<0.001). Additional surgeries were performed in 5 cases. 3 additional procedures were initially planified in the surgical program: one adjacent L3-L5 ligamentoplasty above a L5S1 TDR and two L5S1 TDR cases had additional laminectomies. Fusion at the index level was secondary performed in 2 L4L5 TDR cases but the secondary posterior fusion did not bring improvement. In the 56 remaining patients none experienced facet joint pain. One patient with sacroiliac pain needed local injections. Radiological outcomes were studied on 56 cases (exclusion of 5 cases with additional surgeries). The mean location centers of the index level and adjacent discs were comparable to those previously published in asymptomatic patients. According to the definition of Ziegler, all of our cases remained grade 0 for disc height (within 25% of normal). Discussion. The silent block design of LP-ESP provides an interesting specificity. It could be the key factor that makes the difference regarding facets problems and instability reported with other implants experimentally or clinically. Unfortunately no other comparative TDR series are available yet in the literature. Conclusion. This series reports significant improvement in mid-term follow up after TDR which is consistent with previously published studies but with a lower rate of revision surgery and no adjacent level disease pathologies. The radiographic assessment of the patients demonstrated the quality of functional reconstruction of the lumbar spine after LP ESP viscoelastic disc replacement

Objectives. The main objective of our study was to determine the treatment effect of corticosteroids in peri-radicular infiltration for radicular pain. We also examined whether there was any effect on the need for subsequent interventions such as additional root blocks and/or surgery. Subjects and Method. In a randomised, double blind controlled trial, 150 eligible patients with radicular pain and unilateral symptoms who failed conservative management were randomised for a single injection with bupivacaine and methylprednisolone (b+s) or bupivacaine (b) alone. The outcome measures used included the Oswestry Disability Index (ODI), Low Back Outcome Score (LBOS), Visual Analogue Score (VAS) for leg pain and back pain and patient's subjective level of satisfaction of the outcome. Results. We recruited 76 patients in the b only group and 74 patients in the b+s group. There was no statistically significant difference in the outcome measures between the groups at 3 months (change in ODI [p=0.2], change in VAS [back pain, p=0.28; leg pain, p=0.67]. Subgroup analysis revealed that there was no statistically significant difference in the change in scores between the stenotic group and disc herniation group at 3 months. At 1 year follow-up data was available for 86% of the patients. There was no statistically significant difference in the rate of further interventions in either group. Conclusion. Clinical improvement occurs in both groups of patients. Corticosteroids did not provide additional benefit. There is no difference in the need for further root blocks or surgery

Introduction. Functional deficits persist in a significant percentage of total hip arthroplasties (THA), leading to patient dissatisfaction. Spinal stenosis is a leading cause of chronic disability and lower extremity weakness. Although previous studies have evaluated the potential benefit of THA on back pain, none have reported the effects of spine disability on functional outcomes and patient satisfaction with THA. Methods. 244 primary THAs (233 patients) with minimum 2-year follow-up rated their satisfaction, return to activity, and standard hip outcomes using the Oxford Hip Score (OHS). History of lumbar spine pain, lumbar surgery, and daily activity limitations was documented and an Oswestry Disability Index (ODI) score was calculated. Results. 151 of 244 (62%) patients reported a history of back problems: 35 patients (14%) – history of lumbar surgery, 91 (37%) – daily low back pain, and 97 (40%) – back pain that limited activity. Patients with a history of back problems had lower OHS scores than those without, p=0.0001. Pain relief was reported by 93% versus resumption of activities in 82% of THA patients, p=0.025. Increasing spine disability, as determined by ODI, correlated with poor OHS, p<0.0001. Spine disability (ODI) was directly associated with patient dissatisfaction for pain relief (R=0.41, p<0.0001), return to activity (R=0.34, p<0.0001), and overall surgical results (ODI, R=0.38, p<0.0001) at 2 years after THA. Patient age, gender, and BMI were not associated with poor THA outcomes. Conclusions. The majority of THA patients have a history of lumbar spine problems. The Oswestry Spine Disability Index, which is the primary outcome measure of spinal disorders, correlated strongly with poor THA outcomes. Moderate and severe lumbar spine disability directly correlated with worse Oxford Hip Scores. Spine disability was directly associated with THA dissatisfaction

Purpose. To determine if clinical outcomes are correlated with center of rotation (COR) in patients implanted with a viscoelastic total disc replacement (VTDR). Methods. Fifty patients with single-level, symptomatic lumbar DDD between L4 and S1 were enrolled in a clinical trial of a VTDR across three surgical centres. A comprehensive, independent review and statistical analysis of both clinical and radiographic outcomes was performed and analyzed for correlations. Data from preoperative through 2 years were available. The COR was calculated for the index levels and compared to data for an asymptomatic population. Each COR coordinate was classified as abnormal if outside of the 95% confidence interval for an asymptomatic population. Results. At most recent follow-up, 69% of the patients had achieved at least a 15 point Oswestry Disability Index (ODI) improvement. 76% of the patients achieved at least a 10 point improvement. At most recent follow-up, 78% of cases had a normal COR-X and 92% had a normal COR-Y. Results from three statistical tests show the association between COR-X and outcomes. 1) Based on latest available time point for each patient, the improvement in ODI score was significantly better for patients with a normal anterior-posterior (AP) coordinate of the COR (P=0.03). 2) Anterior COR corresponded with anterior placement of the device in the disc space, and patients were almost 7 times less likely to achieve at least a 15 point improvement in the ODI score if the COR was positioned too anteriorly. 3) This effect was also seen in the average AP coordinate of the COR for patients who achieved a 15 point ODI improvement. Conclusions. A viscoelastic TDR can restore a normal COR. This is the first study to show that restoration of a normal COR correlates with a significant and clinically relevant improvement in patient disability

The Nerve Root Sedimentation Sign in transverse magnetic resonance imaging has been shown to discriminate well between selected patients with and without lumbar spinal stenosis (LSS), but the performance of this new test, when used in a broad patient population, is not yet known (Barz et al. 2010). We conducted a retrospective study of consecutive patients with suspected LSS from 2004–2006, before the sign had been described, to assess its association with health outcomes. Based on clinical and radiological diagnostics, patients had been treated with decompression surgery or conservative treatment (physical therapy, oral pain medication). Changes in the Oswestry Disability Index (ODI) from baseline to 24 month follow-up were compared between Sedimentation Sign positives and negatives in both treatment arms. Of the 146 included patients (52% female, mean age 59 yrs), 71 underwent surgery. Baseline ODI in this treatment arm was 52%, the sign was positive in 44 patients (mean ODI improvement 25 points) and negative in 27 (ODI improvement 24), with no significant difference between groups. In the 75 patients of the conservative treatment arm, baseline ODI was 44%, the sign was negative in 45 (ODI improvement 17), and positive in 30 (ODI improvement 5). Here a positive sign was associated with a smaller ODI improvement compared with sign negatives (t-test, p=0.003). This study allowed an unbiased clinical validation of the Sedimentation Sign by avoiding it influencing treatment selection. In the conservative treatment arm a positive sign identifies a group of patients who are less likely to benefit. In these cases, surgery might be effective; however, this needs confirmation in prospective studies

To investigate clinical outcome scores in surgically treated patients with either spontaneous or postoperative pyogenic spondylodiscitis after 3, 12 and 24 month. 70 consecutive patients (mean age 64y; male n=33 female n=27) underwent surgical treatment due to pyogenic spondylodiscitis with or without epidural abscess at our department from 2011 to 2013. We performed either microsurgical debridement or debridement in combination with ventral support employing dorsally instrumented spondylodesis followed by bracing and antibiotic therapy up to 12 weeks. European life quality score (EQ-5D), Oswestry disability index (ODI) and visual analogue scale for pain (VAS) were recorded 3, 12 and 24 month after surgery. Length of hospital stay (LOS) was 25,3 days. The Mean time to presentation at our spine center and diagnosis was 3,8 weeks. Distribution of inflammation was lumbar in 66 (94%) and thoracic in 4 (6%) patients. Thirtyfour patients (49%) had isolated spondylodiscitis (SD). Epidural abscess (ED) was found in 26 patients (37%). Ten patients (14%) showed a combination of SD and ED. SD or ED were predominantly found after previous surgery at the same or contiguous level 38 (54%). Nine patients (13%) suffered from ED or SD after previous lumbar epidural steroid injections (LESI). Spontaneous idiopathic inflammation was found only in 13 cases (19%). Standardized follow-up (FU) protocol was scheduled at 3, 12, and 24 month. FU rate was 60%. Healing of the inflammation was the rule. In our study cumulative EQ-5D increased from 0.47 to 0,80. ODI decreased from 41.1 to 24.3 and VAS concerning back pain decreased from 58.4 to 22.6 VAS according sciatica decreased from 46.8 to 20.5. Due to an increasing number of spine surgeries and spinal interventions as well as the increasing age and morbidity of patients, spinal surgeons have to deal more often with the diagnosis pyogenic spondylodiscitis. Standardized conservative or radical surgical treatment strategies in order to achieve good results according to patients life quality are gaining more importance

Background. Foraminal stenosis is often encountered in patients undergoing decompression for spinal stenosis. Given the increased resection of facets and the presence of the more sensitive dorsal root ganglion, it is hypothesized that patients with foraminal stenosis have poorer postoperative outcomes. Methods. Thirty-one patients undergoing decompression without fusion for lumbar spinal stenosis were evaluated. The degree of foraminal stenosis was determined by 2 independent reviewers for absence of fat around the nerve roots. ImageJ digital imaging software was also used to evaluate the foraminal area. Patients with foraminal stenosis were compared with those without using the Oswestry Disability Index (ODI) and a numerical pain scale for back and leg pain at a minimum of 1 year follow-up. Results. Twenty patients in the foraminal stenosis group were compared with 11 without foraminal stenosis. There were no significant differences between the 2 groups regarding age, sex, comorbidities, number of levels operated on, preoperative ODI, back pain or leg pain scores. The foraminal area was significantly smaller in the foraminal stenosis group. Patients without foraminal stenosis reported significant improvements in ODI (mean 26.0), back pain (mean 3.1) and leg pain scores (mean 5.5). Patients with foraminal stenosis reported significant improvements in ODI (mean 18.8) and leg pain (mean 2.5) but not in back pain (mean 0.3). Comparing the 2 groups, the patients with foraminal stenosis had significantly less improvement in back pain (p = 0.02) and leg pain (p = 0.02). Conclusion. The results of this study suggest that presence of foraminal stenosis is a negative predictor for successful outcome following decompression surgery. This may be related to the increased instability that occurs when a foraminotomy is required. Spinal fusion may reduce this effect, and further study is required. NO DISCLOSURES

Background. There are no published studies investigating predictive values of psychological distress on effectiveness of epidural injection. Aims. To evaluate response to epidural injection (EI) in patients with chronic lower back pain (CLBP) with and without psychological distress. Methods. 96 patients with CLBP were recruited to this prospective cohort study. They had preoperative level of distress measured using Modified Zung Index (MZI) and Modified Somatic Perception Questionnaire (MSPQ); pain with Visual Analogue Score (VAS) and McGill Pain Questionnaire (MPQ); back related disability with Oswestry Disability Index (ODI). Fluoroscopic caudal EI comprising 80 mg methylprednisolone and 8 mg of lignocaine was performed. Scores were repeated at 6, 12, and 26 weeks. Successful outcome was Minimal Clinically Important Change (MCIC) in any given measure. Results. There were 62.5% not-distressed patients, 3.1% somatising, 15.6% depressed and 18.8% with mixed distress. Preoperative VAS was 82.4, MPQ 18.2 and ODI 51.6. Distress was associated with worse MPQ and ODI. Average VAS and MPQ improved significantly at 6 and 26 weeks. Mean change of ODI was significant but less than MCIC. Average magnitude of change of VAS and ODI did not differ between distressed and not-distressed. MPQ improved significantly more in the distressed. MZI was significant predictor of VAS-MCIC at 6 weeks while MZI and MSPQ at 6 months. None could predict this outcome independently. MSPQ was the only individual predictor of MPQ-MCIC at any time; MSPQ≥8 could predict MPQ-MCIC with 53%-sensitivity and 78%-specificity. MZI was significant predictor of ODI-MCIC but not individually.88% patients were satisfied with the treatment at 6 weeks and 63% at 6 months (significantly higher rate if somatising). Conclusions. Early psychological screen was correlated with outcome following epidural injection in CLBP and capable of predicting some response to treatment. Minimal, short-lived improvement of distress was not related to post-treatment CLBP measures

Introduction and aims. 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. Method and Materials. 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 t-test with 95% confidence interval, statistical significance was investigated. Results. Data analysis shows that there are no significant differences (p>0.05) in either overall patient satisfaction or outcomes between patients of the surgeon vs physiotherapists. Patients of the surgeon were found to be more satisfied with the procedure itself (p< 0.05). Conclusion. Physiotherapists are able to provide spinal injections with equal efficacy to spinal surgeons, with no reduction in overall patient outcome. Benefits of this scheme include greater number of spinal injections performed. Therefore, reducing the overall waiting times. Further, multi-centre studies on larger populations are required to investigate injection treatment by physiotherapists

Introduction. In all traumatic injury there is a clear relationship between the structural tissue damage and resultant disability after recovery. There are no publications that compare significant thoracolumbar osseous injury to non specific soft tissue injury. Aim. To compare spinal outcome measures between patients with self reported back pain in the workplace perceived as injury to those having sustained structural injury in the form of an unstable thoracolumbar fracture requiring surgical stabilisation. Method. Two consecutive cohorts consisting of 23 patients with healed thoracolumbar fractures and 21 patients with a perception of work related injury were compared. Patient outcomes were measured using the Oswestry Disability Index (ODI), Low Back Outcome score (LBOS), Modified Somatic Perception (MSP) and Modified Zung Depression (MZD) indices. Results. 23 patients (8 females; 15 males) with spinal fractures (group 1), of average age 42 years were followed up for a mean of 41 months post trauma and compared to 21 patients (6 females; 15 males) with self reported back pain pursuing compensation claims, (group 2), of average age 47 years, mean time since perceived injury of 42 months. Both groups were comparable in terms of age and sex. The average ODI in group 1 was 28% (SD 18.5) compared to 52% (SD 17.1) in group 2 (P: 0.0003). Similarly, LBOS was 39.7 Vs 20.3 (P: 0.0003); MSP 4.3 Vs 9.65 (P: 0.03); and MZD 20.2 Vs 35.9 (P: 0.001) in groups 1 and 2 respectively. Conclusion. Despite high energy trauma and significant structural damage to the spine, post-traumatic patients had better spinal outcome scores in all measures (ODI, LBO, MSP, MZD). There is no ‘dose-response’ relationship to functional outcomes. In fact, the disability seems greater in the lower energy injury which is unique in trauma care

Greater trochanteric pain syndrome (GTPS) is common, yet the impact on function and quality of life has not been measured. The aim of this study was to quantify the impact on function and quality of life, comparing the results to people with severe hip osteoarthritis and an asymptomatic control group. Forty two people with GTPS – including 11 not actively seeking treatment and 11 seeking surgical treatment, 20 with severe hip osteoarthritis (OA), and 23 age and sex matched asymptomatic participants (ASC) where recruited from public and private hospitals, and the community. Upon confirming meeting inclusion and exclusion criteria participants were interviewed. Exclusion criteria included lumbar nerve root signs; inflammatory, neoplastic and metabolic disorders. Measured used were the Harris hip score (HHS); the Oswestry disability index (ODI); the Australian quality of life instrument (AQoL); the Functional co-morbidity index (FCI); and fulltime work assessments. No difference was found between the GTPS and the OA group on the HHS, ODI, AQoL or the FCI measures. Both symptomatic groups were significantly more disabled than the ASC group on the HHS and ODI (p<0.001). The GTPS and OA groups had lower AQoL than the ASC group (p<0.001); and higher FCI results than the ASC group (GTPS vs ASC, p=0.005; OA vs ASC, p=0.019). GTPS participants were least likely to be in full time work; full time work participation probability (95% C.I.): GTPS Prob=0.288 (0.160 to 0.463), OA Prob= 0.518 (0.273 to 0.753); ASC group of Prob=0.676 (0.439 to 0.847). People with GTPS have similar levels of pain, disability and quality of life, but are less likely to be in full time employment than people with severe hip OA which puts them at risk of economic hardship. Research on conservative and surgical treatments should measure pain, disability and work participation

We hypothesised whether MIS techniques confer any benefit when treating thoracolumbar burst fractures. This was a prospective, non-randomised study over the past seven years comparing conservative (bracing:n=27), conventional surgery (open techniques:n=23) and MIS techniques (n=21) for stabilisation and correction of all thoracolumbar spinal fractures with kyphosis of >20. 0. , using Camlok S-RAD 90 system (Stryker Spine). All patients previously had normal spines, sustained only a single level burst fracture (T12, L1 or L2) as their only injury. Age range 18–65 years. All patients in both operatively treated groups were corrected to under 10. 0. of kyphosis, posteriorly only. All pedicle screws/rods were removed between 6 months and 1 year post surgery to remobilise the stabilised segments once the spinal fracture had healed, using the original incisions and muscle splitting/sparing techniques. Patients were assessed via Oswestry Disability Index (ODI) and work/leisure activity status 1 year post fracture. The conservatively treated group fared worst overall, with highest length of stay, poorest return to work/activity, and with a proportion (5/27) requiring later intervention to deal with post-traumatic deformity. 19/27 returned to original occupation, at average 9 months. ODI 32%. Conventional open techniques fared better, with length of stay 5 days, most (19/23) returning to original work/activity, and none requiring later intervention. Average return to work was at 4 months. ODI 14%. MIS group fared best, with shorter length of stay (48 hours), all returning to original work/activity at average 2 months, and none requiring later intervention. ODI negligible. There was no loss of correction in either operatively treated groups. The Camlok S-RAD 90 system is a powerful tool for correction of thoracolumbar burst fractures, and maintains an excellent correction. MIS techniques provide the best outcomes in treating this group of spinal fractures, and offer patients the best chance of restoration to pre-fracture levels of activity

We describe the clinical results of a technique of direct pars repair stabilised with a construct that consists of a pair of pedicle screws connected with a modular link that passes beneath the spinous process. Tightening the link to the screws compresses the bone grafted pars defect providing rigid intrasegmental fixation. 20 patients aged between 9 and 21 years were included in this prospective study. Each of the patients had high activity levels and suffered from significant back pain without radicular symptoms or signs. Patients had either no or grade I spondylolisthesis. Definitive pseudoarthrosis and fracture were confirmed via computerize tomography (CT). Magnetic resonance imaging was performed in every patient to assess the adjacent disc spaces which demonstrated normal signal intensity. A midline incision was used for surgery. The pars interarticularis defect was exposed and filled with autologous iliac crest bone graft prior to screw insertion. After screw insertion, a link was contoured to fit, and placed just caudal to the spinous process, deep to the interspinous ligament of the affected level, and attached to each pedicle screw. There was early mobilization post-operatively without a brace. The average inpatient stay was 3 days. Post-operative complications included 1 superficial wound haematoma and two superficial wound infections which responded to antibiotic treatment. Follow-up was at 6 weeks, 6 months and at 18 months, and 24 months. Clinical assessments for all patients was via the Oswestry disability index (ODI) and visual analogue scores (VAS). At the latest follow-up, 18 out of the 20 patients showed a significant (p<0.05) improvement in their ODI and VAS scores. The mean post-operative ODI score was 8%. All patients had radiographs and CT scans which showed fusion rates of 80% in those patients followed up for a minimum of 24 months. This new technique for direct pars repair demonstrates high fusion rates in addition provides the possible benefits of maintaining adjacent level motion. Clinically this group had good-to excellent functional outcomes as indicated by visual analogue scales and the Oswestry Disability Index in 18 out of 20 patients studied with a minimum follow-up of 2 years
