Background

Social context may be important in chronic pain. One focus is reactions to pain between persons with LBP and their partners. Researchers have investigated partner reactions and found influences on pain levels and psychological outcomes, but little is known about factors underpinning these reactions.

Purpose and background. Although low back pain (LBP) with leg pain, is considered by most a poor prognostic indicator, it is at the same time believed to have a favourable natural resolution, and is often treated along similar lines to non-specific LBP, in line with current guidelines. It is unclear whether patients with LBP and leg pain are a distinct subgroup that might benefit from early identification and targeted interventions. We set out to investigate the impact of LBP with leg pain on health outcomes and health resources compared with that of LBP alone, and to explore which factors contribute to the observed disability outcomes. Methods. A systematic literature search of all English language peer reviewed publications was conducted using Medline, EMBASE, and CINAHL for the years 1994 to 2009. Results. Of the 89 papers retrieved, 9 were included in the review. The heterogeneity of data allowed only for narrative analysis of findings. All studies reported worsening baseline health status in terms of poorer self-assessment and increasing use of health care the further the radiation of leg pain. Differences in quality of life measures were higher for physical than for mental health dimensions. Pain and disability outcome at follow up assessment appeared to be less favourable in this group than for individuals with LBP alone. Conclusion. LBP with leg pain is associated with poorer health outcomes and increased use of health resources. These findings argue for early identification of these cases by health care professionals and for pursuing effective treatments rather than simply treating similarly to non-specific LBP

Background and study purpose. Low mood and distress are commonly reported with by people with persistent musculoskeletal pain and may be mislabelled as ‘depression’. In order to understand how pain-related distress is conceptualised and managed in primary care consultations, we explored understanding of pain-related distress and depression from the perspectives of people with persistent musculoskeletal pain and general practitioners (GPs). Method and results. Semi-structured interviews with 21 GPs and 21 people with persistent musculoskeletal pain were conducted. The majority of people with pain had back pain (15/21). Data were analysed thematically using constant comparison techniques. Participants described challenges distinguishing between distress and depression in the context of persistent pain but described strategies to make this distinction. Some people with pain described how acceptance of their situation was key, involving optimism about the future and creation of a new identity. Some GPs expressed ‘therapeutic nihilism’, with uncertainty about the cause of pain and thus how to manage people with both pain and distress, whilst GPs who could identify and build on optimism with patients described how this could help the patient to move forwards. Conclusion. This study offers a model for the primary care consultation with patients presenting with pain-related distress. GPs should recognize the impact of pain on the patient, support the person in acceptance of the pain, explore how the person feels about the future, encourage optimism, and support self-management strategies.

Aims. We compared decompression alone to decompression with fusion surgery for lumbar spinal stenosis, with or without degenerative spondylolisthesis (DS). The aim was to evaluate if five-year outcomes differed between the groups. The two-year results from the same trial revealed no differences. Methods. The Swedish Spinal Stenosis Study was a multicentre randomized controlled trial with recruitment from September 2006 to February 2012. A total of 247 patients with one- or two-level central lumbar spinal stenosis, stratified by the presence of DS, were randomized to decompression alone or decompression with fusion. The five-year Oswestry Disability Index (ODI) was the primary outcome. Secondary outcomes were the EuroQol five-dimension questionnaire (EQ-5D), visual analogue scales for back and leg pain, and patient-reported satisfaction, decreased pain, and increased walking distance. The reoperation rate was recorded. Results. Five-year follow-up was completed by 213 (95%) of the eligible patients (mean age 67 years; 155 female (67%)). After five years, ODI was similar irrespective of treatment, with a mean of 25 (SD 18) for decompression alone and 28 (SD 22) for decompression with fusion (p = 0.226). Mean EQ-5D was higher for decompression alone than for fusion (0.69 (SD 0.28) vs 0.59 (SD 0.34); p = 0.027). In the no-DS subset, fewer patients reported decreased leg pain after fusion (58%) than with decompression alone (80%) (relative risk (RR) 0.71 (95% confidence interval (CI) 0.53 to 0.97). The frequency of subsequent spinal surgery was 24% for decompression with fusion and 22% for decompression alone (RR 1.1 (95% CI 0.69 to 1.8)). Conclusion. Adding fusion to decompression in spinal stenosis surgery, with or without spondylolisthesis, does not improve the five-year ODI, which is consistent with our two-year report. Three secondary outcomes that did not differ at two years favoured decompression alone at five years. Our results support decompression alone as the preferred method for operating on spinal stenosis.

Background. Various studies have highlighted issues regarding the prevalence of back pain due to lead apron use. The health and safety executive guidelines on personal protection equipment state that an employee should be able to carry the weight of a lead apron without injury (HSE, 2017). It has been suggested that wearing a 15 pound lead apron can place pressures of up to 300 pounds per square inch of the intervertebral discs (Khalil, 1993), ‘interventionalist's disc disease’ has been identified as a confirmed entity (Ross et al. 1997). Aim. To evaluate the prevalence of back pain amongst theatre staff and correlate this to lead apron use. Methods. Data collection (November 2018 – February 2019) involved the distribution of questionnaires to staff using lead aprons on a routine basis at Salisbury District Hospital. Results. A total of 59 members of staff responded to the questionnaire. The results showed that 30% staff had a previous history of back pain, of these 61% felt that their back pain had worsened since wearing lead aprons. 46% of staff who did not have any previous history of back pain developed new back pain since wearing lead aprons. A total of 46% of staff feel that their back pain has been exacerbated or caused by lead apron wearing. Conclusion. The study highlights that a significant proportion of staff had new or worsening back pain due to lead apron use. This can lead to time off work and could lead to unsafe practice around ionising radiation. No Conflicts of interest No funding obtained

Aims. To determine the value of scoliosis surgery, it is necessary to evaluate outcomes in domains that matter to patients. Since randomized trials on adolescent idiopathic scoliosis (AIS) are scarce, prospective cohort studies with comparable outcome measures are important. To enhance comparison, a core set of patient-related outcome measures is available. The aim of this study was to evaluate the outcomes of AIS fusion surgery at two-year follow-up using the core outcomes set. Methods. AIS patients were systematically enrolled in an institutional registry. In all, 144 AIS patients aged ≤ 25 years undergoing primary surgery (median age 15 years (interquartile range 14 to 17) were included. Patient-reported (condition-specific and health-related quality of life (QoL); functional status; back and leg pain intensity) and clinician-reported outcomes (complications, revision surgery) were recorded. Changes in patient-reported outcome measures (PROMs) were analyzed using Friedman’s analysis of variance. Clinical relevancy was determined using minimally important changes (Scoliosis Research Society (SRS)-22r), cut-off values for relevant effect on functioning (pain scores) and a patient-acceptable symptom state (PASS; Oswestry Disability Index). Results. At baseline, 65 out of 144 patients (45%) reported numerical rating scale (NRS) back pain scores > 5. All PROMs significantly improved at two-year follow-up. Mean improvements in SRS-22r function (+ 1.2 (SD 0.6)), pain (+ 0.6 (SD 0.8)), and self-image (+ 1.1 (SD 0.7)) domain scores, and the SRS-22r total score (+ 0.5 (SD 0.5)), were clinically relevant. At two-year follow-up, 14 out of 144 patients (10%) reported NRS back pain > 5. Surgical site infections did not occur. Only one patient (0.7%) underwent revision surgery. Conclusion. Relevant improvement in functioning, condition-specific and health-related QoL, self-image, and a relevant decrease in pain is shown at two-year follow-up after fusion surgery for AIS, with few adverse events. Contrary to the general perception that AIS is a largely asymptomatic condition, nearly half of patients report significant preoperative back pain, which reduced to 10% at two-year follow-up.

Introduction. We report the outcomes of minimally invasive technique for posterior lumbar interbody fusion (PLIF) procedure using Hollow Modular Anchorage (HMA) screws supplemented by routine pedicle screw fixation (Dynesis). Patients and Methods. Seventy-nine patients, who had undergone PLIF procedure using HMA screws supplemented by pedicle screw fixation, were included. Patients deemed suitable for surgery following discography under sedation, with Marcaine instillation establishing reducibility of the listhesis and temporary relief of symptoms. Clinical outcome included visual analogue scale scores for leg pain and back pain, Oswestry Disability Index (ODI) and SF-36 questionnaires. Results. Average age was 59 (range: 27-85). Mean follow- up was 5 years (range: 1-10). All cases went into union. None were lost to follow-up. Average length of stay was 24 hours (18-72 hours). All clinical parameters improved except SF-36. Mean ODI improved from 54 (range: 44-89) preoperatively to 33 (17-55) postoperatively (statistically significant, p=0.004). Back pain relief improved in visual analogue scale from average of 68 (range: 60-100) preoperatively to 37 postoperatively (range: 8:46) (statistically significant, p= 0.022). Leg pain relief improved from 53 (range: 31-100) preoperatively to 28 postoperatively (range: 4:60) (statistically significant, p= 0.007). Although mean SF-36 score improved from 37 (range: 10-41) preoperatively to 47 (range: 53-94) postoperatively (statistically insignificant, p=0.592). Complications included: one infection required removal of implant; two temporary motor weaknesses related to L5 nerve root; four required removal of the pedicle screw due to pain or loosening. Discussion. Our results are encouraging. Interbody HMA screws are porous hollow titanium screws with favourable biomechanical characteristics. Rather than square cages, they permit accurate placement of implant. Dynesys offers the option of extension and flexible support for the adjacent segment. Conclusion. PLIF supplemented with pedicle fixation is a reliable and safe procedure for degenerative spondylolisthesis. SF-36 is less sensitive for assessing spinal surgery outcome

Purpose. To determine, for the first time, how back pain is portrayed in the United Kingdom press. Methods and Results. LexisNexisTM Professional search engine was utilised to retrieve articles from all national newspapers over a six months containing the terms “back pain/backpain/back ache/backache” from May to October 2009. 284 relevant articles were retrieved. Of these tabloids accounted for 62% and broadsheets for 38%. Back pain was the sole topic in 7%, a main topic in 18% and mentioned in passing in 75%. 15% were essentially case reports and the tone was neutral in 95%, positive in 2.5% and negative in 2.5%. The cause of back pain was mentioned in 11% of articles- trauma accounted for 50% and disc disease and spinal deformity for 20% each. Only 0.3% of articles discussed litigation. Articles mentioned new physiotherapy regimes in 7%, new forms of alternative therapy in 7%, new surgical techniques/technologies in 2% and new medications in 1%. They were significantly more likely to mention new non-surgical techniques- Fishers' Exact Test p=0.01. Articles were alternative therapy related in 3%, physiotherapist related in 2%, surgeon related in 1% and pain specialist related in 1%. 10% of papers included a quote from an “expert” of which 23% were Spine Surgeons, 16% GP's, 13% Sports Physicians, 13% alternative therapists, 10% pain specialists and 7% physiotherapists. Overall, 98% of articles were of a neutral tone and 1% were of a positive tone or negative tone. Articles concerning physiotherapists or new surgical techniques/technologies were significantly more likely to be of a positive overall tone than the other articles- Fishers' Exact Test p=0.04. Conclusions. Back pain receives a considerable amount of attention in the United Kingdom press. Much of this currently concentrates on isolated case reports, the aetiology of back pain is poorly represented, quoted “experts” are frequently non-medical and new surgical treatments receive significantly less attention than new non-surgical treatments. The press play an important role in educating and informing the general public. The stories they cover ad how they cover them have a powerful influence on public perceptions. We need to do more to engage with the press and positively influence their reportage

We studied 27 patients with low back pain and unilateral L5 or S1 spinal nerve root pain. Significant radiological changes were restricted to the symptomatic root level, when compared with controls. Low back and leg pain were graded on a visual analogue scale. Dermatomal quantitative sensory tests revealed significant elevations of warm, cool and touch perception thresholds in the affected dermatome, compared with controls. These elevations correlated with root pain (warm v L5 root pain; r = 0.88, p < 0.0001), but not with back pain. Low back pain correlated with restriction of anteroposterior spinal flexion (p = 0.02), but not with leg pain. A subset of 16 patients underwent decompressive surgery with improvement of pain scores, sensory thresholds and spinal mobility. A further 14 patients with back pain, multilevel nerve root symptoms and radiological changes were also studied. The only correlation found was of low back pain with spinal movement (p < 0.002). We conclude that, in patients with single level disease, dermatomal sensory threshold elevation and restriction of spinal movement are independent correlates of sciatica and low back pain

Background. PROMs have become an integral assessment tool of clinical effectiveness and patient satisfaction. To date, PROMs for lumbar discectomy are not an NHS requirement, although voluntary collection via the British Spine Registry is encouraged. Despite this, PROMs for day case microdiscectomy is scarcely reported. We present PROMs for day case microdiscectomy at Lancashire Teaching Hospitals. Aims. 1). To review PROMs to quantify leg pain, back pain, EQ5D and ODI scores. 2). Evaluate PROMs data collection compliance. Methods. We studied PROMs data, taken prospectively as part of routine clinical care for all patients who underwent single level day case microdiscectomy between January 2013 to December 2015. PROMs included VAS for back and leg pain, EQ5D and ODI scores. Preoperative PROMs were compared to all available postoperative PROMs at 3 months, 6 months, 12 months and 24 months. Paired student T-tests were used to compare preoperative to postoperative scores. Results. Preoperative PROMs were recorded for 132 patients. Postoperative PROMs were recorded for 48 patients at 3 months, 51 patients at 6 months, 37 patients at 12 months and 15 patients at 24 months. Significant postoperative improvements (p<0.05) were found at all time points for back pain, leg pain, EQ5D and ODI, with the exception EQ5D at 24 months (p = 0.10). Conclusion. There was significant improvement in VAS back and leg scores, as well as ODI scores over 24 months. Further work is needed to improve compliance with postoperative PROMs and to optimise the benefit of these health assessment tools. No conflicts of interest. No funding obtained

Background:. Identification of nerve root involvement (NRI) in patients with low back-related leg pain (LBLP) can be challenging. Diagnostic models have mainly been developed in secondary care with conflicting reference standards and predictor selection. This study aims to ascertain which cluster of items from clinical assessment best identify NRI in primary care consulters with LBLP. Methods:. Cross-sectional data on 395 LBLP consulters were analysed. Potential NRI indicators were seven clinical assessment items. Two definitions of NRI formed the reference standards: (i) high confidence (≥80%) NRI clinical diagnosis (ii) high confidence (≥80%) NRI clinical diagnosis with confirmatory magnetic resonance imaging (MRI) findings. Multivariable logistic regression models were constructed and compared for both reference standards. Model performances were summarised using the Hosmer-Lemeshow statistic and area under the curve (AUC). Bootstrapping assessed internal validity. Results:. NRI clinical diagnosis model retained five items. The model with MRI in the reference standard retained six items. Four items remained in both models: below knee pain, leg pain worse than back pain, positive neural tension tests, neurological deficit (myotome, reflex or sensory). NRI clinical diagnosis model was well calibrated (p=0.17) and discrimination was AUC 0.96 (95%CI: 0.93, 0.98). Performance measures for clinical diagnosis plus confirmatory MRI model showed good discrimination (AUC 0.83, 95% CI: 0.78, 0.86) but poor calibration (p=0.01). Bootstrapping revealed minimal overfitting in both models. Conclusion:. A cluster of items identified NRI in LBLP consulters. These criteria could be used clinically and in research to improve accuracy of identification and homogeneity of this subgroup of low back pain patients

Background. 60% of back pain patients report pain radiation in the leg(s), which is associated with worse symptoms and poorer recovery. The majority are treated in primary care, but detailed information about them is scarce. The objective of this study is to describe the characteristics of patients with back and leg pain-seeking treatment in primary care. Methods. Adult patients consulting their GP with back and leg pain were invited to the study. Participants completed questionnaires including sociodemographic, physical and psychosocial measures. They also underwent standardised clinical assessments by physiotherapists, and received an MRI scan. Results. 609 patients participated with 67.5% reporting pain below the knee. 62.6% were female, sample mean (SD) age 50.2 (13.9). 367 (60.7%) were in paid employment with 39.7% reporting time off work. Mean disability (RMDQ) was 12.7 (5.7) and mean pain intensity was 5.6 (2.2) and 5.2 (2.4) for back and leg respectively. Mean sciatica bothersomeness index (SBI) score was 14.9 (5.1). 74.2% (452/609) were clinically diagnosed as having sciatica. Patients in the sciatica group reported significantly higher levels of leg pain and SBI scores, leg pain worse than back pain and pain below the knee. Neuropathic pain was more prevalent in patients with referred leg pain. Conclusion. This primary care cohort reported high levels of disability and pain. Three quarters were diagnosed with sciatica. Follow-up of this cohort will investigate the prognostic value of their baseline characteristics.

Purpose and Background. This pilot study aimed to determine the accuracy of lumbar spine combined movement (CM) testing for diagnosing facet joint mediated pain, by comparing CM to medial branch blocks (MBB) - the gold standard in the diagnosis of facet joint pain. A regular compression pattern of CM combines active extension and lateral flexion, which is believed to compress the facet joints greater than physiological uni-planar movements. Method and Results. 96 patients attending a pain clinic day case unit for diagnostic MBB were recruited. Patients' pain responses to CMs were measured prior to and thirty minutes following MBB. The effect of weight bearing and recumbence, RMDQ, EQ-5D and MYMOP were also measured. The regular compression CM test had 80% sensitivity (95%CI: 71% to 89%) and 50% specificity (95%CI: 28% to 71%). The regular compression CM group had the largest pre-post VAS difference (median 4 points). The patients whose pain was not relieved in recumbence (n=15) showed a significant VAS difference of 6 points p=0.001). There was a significant positive correlation between the pre and post pain scores, p<0.001. There was no association between MBB response and RMDQ, EQ-5D, MYMOP scores, duration of symptoms or standing as a provoking activity. Conclusion. Regular compression CM testing can be used as a diagnostic tool to identify patients with facet joint mediated pain, particularly when associated with high pain scores. Low back pain (LBP) provoked by standing and relieved with recumbence are common features in the LBP population but are not indicators of facet joint pathology, contrary to many clinicians' beliefs

To determine if the term “back pain” has uniform meaning to spinal surgeons. A survey of specialists attending an international meeting on spinal surgery. Participants were shown 5 schematic pain drawings and then asked to categorize the pain as either back or leg pain. An international cohort of neurosurgeons, orthopaedic surgeons and trauma surgeons (n=104) attending a European spinal meeting. 67% of participants were orthopaedic surgeons and 22% neurosurgeons. 42% were in full time spinal practice. 50% had been in independent practice for 7 years or more. There was no statistical difference in the responses of neuro- and orthopaedic surgeons (Fisher's test, p>0.05). The more rostral the pain, the more likely it was to be deemed “back pain”. However, unilateral pain was more likely to be deemed “leg pain” than its bilateral symmetrical equivalent no matter how rostral the distribution. Unilateral mid-lumbar pain was considered “back pain” by 48%, symmetrical bilateral mid-lumbar pain in 87%. Pain in the buttocks was considered “back pain” in 50% whether unilateral or bilateral. This study demonstrates significant discrepancy in what is considered to be back pain and leg pain by a broad spectrum of spinal surgeons. Back pain and leg pain are often investigated and managed in different ways. This differentiation is difficult to justify until we know the answer to the question, what is back pain?

Aims. The purpose of this study was to investigate the risk of additional surgery in the lumbar spine and to describe long-term changes in patient-reported outcomes after surgery for lumbar disc herniation in adolescents and young adults. Patients and Methods. We conducted a retrospective study design on prospectively collected data from a national quality register. The 4537 patients were divided into two groups: adolescents (≤ 18 years old, n = 151) and young adults (19 to 39 years old, n = 4386). The risk of additional lumbar spine surgery was surveyed for a mean of 11.4 years (6.0 to 19.3) in all 4537 patients. Long-term patient-reported outcomes were available at a mean of 7.2 years (5.0 to 10.0) in up to 2716 patients and included satisfaction, global assessment for leg and back pain, Oswestry Disability Index, visual analogue scale for leg and back pain, EuroQol five-dimension questionnaire (EQ-5D), and 36-Item Short-Form Health Survey (SF-36) Mental Component Summary and Physical Component Summary scores. Statistical analyses were performed with Cox proportional hazard regression, chi-squared test, McNemar’s test, Welch–Satterthwaite t-test, and Wilcoxon’s signed-rank test. Results. Any type of additional lumbar spine surgery was seen in 796 patients (18%). Surgery for lumbar disc herniation accounted for more than half of the additional surgeries. The risk of any additional surgery was 0.9 (95% confidence interval (CI) 0.6 to 1.4) and the risk of additional lumbar disc herniation surgery was 1.0 (0.6 to 1.7) in adolescents compared with the young adult group. Both age groups improved their patient-reported outcome data after surgery (all p < 0.001). Changes between short- (mean 1.9 years (1.0 to 2.0)) and long-term follow-up (mean 7.2 years (5.0 to 10.0)) were small. Conclusion. The risk of any additional lumbar spine surgery and additional lumbar disc herniation surgery was similar in adolescents and young adults. All patient-reported outcomes improved from preoperative to the short-term follow-up, while no likely clinically important differences between the short- and long-term follow-up were seen within both groups.

Balloon kyphoplasty (BKP) is a minimally invasive treatment for vertebral fractures (VCF) aiming to correct deformity using balloon tamps and bone cement to stabilize the body. Patients with 1 - 3 non-traumatic acute VCF were enrolled within three months of diagnosis and randomly assigned to receive either BKP (N=149) or nonsurgical care (N=151). Follow-up was 2 years. The mean SF-36 physical component summary (PCS) score improved 5.1 points (95%CI, 2.8-7.4; p<0.0001) more in the kyphoplasty than the nonsurgical group at one month, the primary endpoint of the study. Kyphoplasty improved the PCS score by an average of 3.0 points (95%CI, 1.6-5.4; p=0.002) during the two-year follow-up. There was a significant interaction between treatment and follow-up time (p=0.003), indicating that the treatment effect over the year is not uniform across follow-up; a result from early improvement that persists in the kyphoplasty group whereas the nonsurgical group shows more incremental improvement over time. Overall, patients assigned to kyphoplasty also had statistically significant improvements over the two years compared to the control group in global quality of life (EQ-5D), pain relief (VAS), back disability (RMDQ) and days of limited activity (within a two-week period). There was no statistical significant difference between groups in the number of patients with adverse events or new VCF's over 24 months. Compared to the control, BKP improved quality of life and reduced back pain and disability and did not increase adverse events including the risk of new vertebral fractures over 2 years

Introduction. It is becoming increasingly more accepted that Patient Reported Outcome Measures (PROMs) should be used to assess surgical interventions. We report on a pilot study of a generic database with complete pre and post-operative data sets in a UK hospital. Method. 19 cases undergoing lumbar surgery in our institution were prospectively reviewed between January and August 2010. Pre and post–operative data assessing pain, back pain specific function, generic health, work disability and patient satisfaction were collected using a core outcome measures index, EuroQol EQ-5D and Oswestry Disability Index (ODI). Details of surgery and assessment of treatment outcome by the operating surgeon was also assessed. Results. There were 11 males and 8 females. 8 cases were coded as disc herniation, and 11 as spinal stenosis. Levels involved included L3/4 (4), L4/5 (8) and L5/S1 (6). ASA status was 1 (4/19), 2 (12/19) and 3 (3/19). The median operation time for all operations was between 1-2 hours and blood loss was under 500ml for all cases. Complications recorded were one dural tear and one wound infection. Post operatively the COMI score improved from 8.7 to 7 overall (p=0.028) and the leg pain score improved from 8 to 7 overall (p=0.009). The EQ-5D improved from 0.09 to 0.36. The ODI improved from 60 to 40 (p=0.03). Patients reported being satisfied in 73% of cases and the surgeon reported a good or excellent result in 65% of cases. Conclusion. The Spine Tango is an effective and user friendly tool for data collection. Data entry and extraction is easy. It is security enhanced and no Patient identifiable data (PID) is transferred outside the host institution. Data retrieval can be done online with clear-cut graphs and data tables or by downloading data and importing into a statistical package for more complex, analyses

Background and purpose. Trajectories of change over time can illustrate the course of pain. Back pain trajectories have previously been identified among adults. Understanding different patterns of back pain among adolescents could shed light on how persistent back pain develops. We aimed to identify and compare trajectories of back pain among adolescents in the general population. Methods and results. This prospective cohort study followed 1,336 adolescents (initially aged 11 years) every three months for three years, using self-completion questionnaires. Latent class growth analysis was used to cluster subjects into distinct trajectories of back pain. Six clusters were identified. Most subjects (78%) had very low likelihood of back pain throughout follow-up. The second largest cluster (10%) had relatively low and falling probability of back pain. Two clusters (4% each) showed increasing probability of back pain. One cluster had a peak likelihood of pain around age 13 (2%). The smallest cluster (1%) had very high probability of back pain throughout follow-up. The more painful trajectories had significantly fewer males, higher levels of depression and somatization, and lower life satisfaction at baseline, but differed little in physical activity or BMI. Conclusions. Over a fifth of adolescents had trajectories indicating back pain, but a minority had persistent pain problems. Poorer baseline psychological status and female gender were linked with more frequently experienced pain. Trajectories indicating rising or persistent pain might be illustrating the beginning of a long-term pain problem. Headache, facial pain and stomach pain trajectories were also identified in this sample; findings were similar to back pain

The National Institute for Health and Care Excellence has issued guidelines that state fusion for non-specific low back pain should only be performed as part of a randomised controlled trial, and that lumbar disc replacement should not be performed. Thus, spinal fusion and disc replacement will no longer be routine forms of treatment for patients with low back pain. This annotation considers the evidence upon which these guidelines are based.

Lumbar disc herniation (LDH) is uncommon in youth and few cases are treated surgically. Very few outcome studies exist for LDH surgery in this age group. Our aim was to explore differences in gender in pre-operative level of disability and outcome of surgery for LDH in patients aged ≤ 20 years using prospectively collected data. From the national Swedish SweSpine register we identified 180 patients with one-year and 108 with two-year follow-up data ≤ 20 years of age, who between the years 2000 and 2010 had a primary operation for LDH. Both male and female patients reported pronounced impairment before the operation in all patient reported outcome measures, with female patients experiencing significantly greater back pain, having greater analgesic requirements and reporting significantly inferior scores in EuroQol (EQ-5D-index), EQ-visual analogue scale, most aspects of Short Form-36 and Oswestry Disabilities Index, when compared with male patients. Surgery conferred a statistically significant improvement in all registered parameters, with few gender discrepancies. Quality of life at one year following surgery normalised in both males and females and only eight patients (4.5%) were dissatisfied with the outcome. Virtually all parameters were stable between the one- and two-year follow-up examination. LDH surgery leads to normal health and a favourable outcome in both male and female patients aged 20 years or younger, who failed to recover after non-operative management.
