Aims. Gram-negative infections are associated with comorbid patients, but outcomes are less well understood. This study reviewed diagnosis, management, and treatment for a cohort treated in a tertiary spinal centre. Methods. A retrospective review was performed of all gram-negative spinal infections (n = 32; median age 71 years; interquartile range 60 to 78), excluding surgical site infections, at a single centre between 2015 to 2020 with two- to six-year follow-up. Information regarding organism identification, antibiotic regime, and treatment outcomes (including clinical, radiological, and biochemical) were collected from clinical notes. Results. All patients had comorbidities and/or non-spinal procedures within the previous year. Most infections affected lumbar segments (20/32), with Escherichia coli the commonest organism (17/32). Causative organisms were identified by blood culture (23/32), biopsy/aspiration (7/32), or intraoperative samples (2/32). There were 56 different antibiotic regimes, with oral (PO) ciprofloxacin being the most prevalent (13/56; 17.6%). Multilevel, contiguous infections were common (8/32; 25%), usually resulting in bone destruction and collapse. Epidural collections were seen in 13/32 (40.6%). In total, five patients required surgery, three for neurological deterioration. Overall, 24 patients improved or recovered with a mean halving of CRP at 8.5 days (SD 6). At the time of review (two to six years post-diagnosis), 16 patients (50%) were deceased. Conclusion. This is the largest published cohort of gram-negative spinal infections. In older patients with comorbidities and/or previous interventions in the last year, a high level of suspicion must be given to gram-negative infection with blood cultures and biopsy essential. Early organism identification permits targeted treatment and good initial clinical outcomes; however, mortality is 50% in this cohort at a mean of 4.2 years (2 to 6) after diagnosis.

Introduction. The British Spinal Registry (BSR) is a web-based database commissioned by the British Association of Spine Surgeons (BASS) in the UK. It allows auditing of spinal surgery outcomes, patient's safety and overall experience. The clinical data include patient's demographics which is entered into the Registry by medical staff, as well as patient-reported outcome measures (PROM) that is submitted to the Registry by the patient themselves at different time periods post-operatively. It has the ability to register Device and Implants as well as co-ordinate multicentre research. This study is to identify both the staff and patient compliance regarding to data submissions to the BSR at St. George's Hospital NHS Trust. Methods and Materials. Retrospective analysis of the BSR data for all spinal surgeries that was performed at SGH by the three Complex Spinal Surgery Consultants between 1st January 2017 to 31st December 2018. This study period allowed up to 12 months PROM data analysis. Staff and Patient compliance were analysed separately depend on the data they submitted. Results. 404 (n) spinal surgeries were performed over this two-year period. Surgical demographics: 39.4% (159/404) males and 56.2% (227/404) females, 4.5% (18/404) declined to be added. Age ranging from 6 to 92, mean age was 47.9. Staff compliance was 89.4% for the registration of patient data. Trauma and tumour patients were excluded as they are not required to complete any pre-operative PROMs. For the remaining patients, 35.8% (116/324) completed their baseline pre-operative PROMs. A steady decrease in patient compliance for post-operative PROMS was observed: 29.8% (2 weeks), 24.9% (6 weeks), 21.2% (6 months), 17.1% (12 months), and 16.6% (24 months). Conclusions. We identified a poor patient compliance in both pre-operative and post-operative PROMS. Patient questionnaire fatigue can occur over time which results in falling compliance to PROMS in 12 months and 24 months. Moreover, patients who do not provide an email address are less likely to fill in their PROMS. Satisfactory compliance for staff regarding to BSR utilisation are shown. Staff should aim to achieve a higher level of compliance as this will help to keep a record of all spinal surgeries that are performed and any complications that are encountered in a particular centre. Over the past three years, the BSR had introduced various schemes to drive up utilisation including a Best Practice Tariff in 2019. Part of the tariff will be withheld when staff failure to enter patients onto the Registry. Further research is needed to determine why there is such fall off especially with patient compliance and to elucidate potential measures to improve their compliance

Background and purpose of the study. Axial Spondyloarthritis (axSpA) is commonly mistaken as chronic mechanical back pain. Delayed diagnosis averages 5- 8 years with impacts on effective and timely management, outcomes and quality of life. NICE Guidance (2017) highlights the importance of the recognition and referral of suspected axial spondyloarthritis. This study investigated the occurrence of physiotherapy care prior to diagnosis of axSpA within physiotherapy outpatient settings. Methods and results. A retrospective review was performed of all patients diagnosed with axSpA who had received physiotherapy care prior to their diagnosis from 1990–2016. Three or more episodes of care prior to diagnosis was taken as unrecognised axSpA. Information was obtained on diagnostic codes, number of episodes of care and contacts per episode from nine outpatient physiotherapy services. Analysis showed that 263 people (17–69 years) diagnosed with axSpAs had received physiotherapy care prior to diagnosis. Within this population, 103 (44%) had received ≥3 episodes of care. Number of contacts within each episode ranged from 3 (47 people) to 58 (1 person) [median=11 contacts-10 people]. Average time from initial physiotherapy episode to date of diagnosis was 6.4 years (range=0.3–12.8 years, median=8.8 years). The most common assigned diagnostic code was back pain (49.6%), followed by shoulder (11.1%), knee (8.5%), neck (7.7%), ankle/foot (4.3%), tendonitis (4.2%), joint pain (3.4%), osteoarthritis (3.4%) and sacroiliac joint (2%). Conclusion. Findings illustrate the extent of unrecognised axial spondyloarthritis referred to and missed in musculoskeletal physiotherapy practice. It is essential to improve screening and recognition of inflammatory back pain and possible axSpA in musculoskeletal assessments, supported by rheumatology referral guidance.

To analyse if patients with pain improvement following a nerve root block had better outcomes following lumbar microdiscectomy. Fifty-six patients who had a lumbar microdiscectomy were retrospectively followed up to 1 year. All patients had a selective nerve root block (SNRB) as a primary treatment or diagnostic procedure. VAS pain scores were measured daily for 1 week following injection. Patients were grouped into responders and non-responders at 1 week. The 2 groups of patients were followed at 1 year following a lumbar microdiscetomy (LMD). A total of 118 patients had SNRB over a period of 3 years. Of the 56 patients studied retrospectively, 52% and 36% of patients had a VAS score improvement of more than 2 points at 4 days and 1 week respectively. At 1 year post op, 85% of patients had better outcomes in the responder group compared to 74% in the non responder group. Although there was a difference this was not statistically significant. Improvement with SNRB is not a positive predictor of good response with surgery. The ability to evaluate the effect of diagnostic or therapeutic blocks on surgical outcomes is limited by a lack of randomized studies and wide-ranging discrepancies with regard to injection techniques, surgical technique, and outcome measures. More research is needed to determine if diagnostic screening blocks can improve surgical outcomes

Aim. To assess the safety of Zero Profile Interbody fusion (Zero P) device in Anterior Cervical Decompression and fusion (ACDF) for degenerative cervical stenosis. Method. 89 consecutive patients treated with Zero P interbody device from September 2009 to September 2012 were included in this retrospective study. Inclusion criterion: degenerative cervical stenosis with myelopathy, persistent radiculopathy after at least 3 months of failed conservative management. Exclusion criterion: Paediatric population; patients with infection, metastatic disease and trauma. There were 39 females, 50 males with mean age of 55 (ranging from 24 to 84 years). 56 (64%) had surgery at 1 level, 31 (35%) at 2 levels, 1 (1%) at 3 levels. Total number of levels operated were 121. Common levels operated were C56 (62%) and C67 (47%). Majority were operated due to radicular symptoms, 56 (64%) had radicular symptoms, 28(31%) had myelopathy and 5 (5%) Myeloradiculopathy. Results. All had a minimum of 6 months follow up (maximum 2 years). No patient had cage subsidence or extrusion. 1 had superficial infection which settled with antibiotics, 10 (11%) had dysphagia which settled in 6 to12 weeks. Conclusions. Our study demonstrates that ACDF with Zero P can be considered a safe option in management of patients with cervical degenerative stenosis. We would will also recommend a prospective randomised study as a follow on to this retrospective study. Preoperative kyphosis or lordosis did not change the outcome or make the surgical technique any more difficult, hence this implant can also be used in these circumstances.

Objective. To evaluate functional and oncological outcomes following resection of sacral tumours and discuss the strategies for instrumentation. Introduction. Primary malignant tumours of the sacrum are rare, arising from bony or neural elements, or bone marrow in haematological malignancies. Management of such lesions is dictated by anatomy and the behaviour of tumours. Three key issues which arise are the adequacy of tumour resection, mechanical stabilisation and the need for colostomy. Stabilisation is often extensive and can be challenging. Methods. A retrospective review of the surgical management of primary malignant sacral tumours from 2004 - 2009. Results. The study included 46 patients (34 males, 12 females) with an average age of 49 (range 7 – 82). Median duration of symptoms before presentation was 26 months. 25 patients (54%) underwent surgical resection. 8 underwent instrumented stabilisations with fibula strut graft vs. 17 uninstrumented. Mechanical failure of stabilisation was noted in 75% over the follow up period but only one required revision surgery. Colostomy was performed in 10 patients (40%). Mean follow post-operatively was 19.0 months. Wound healing problems were present in 5/25 (20%). There was no difference in infection rates between definitive surgery with and without colostomy. There was one peri-operative death. Local recurrence occurred in 12%(3/25) of operated patients although follow-up period was noted to be short. Conclusions. Mechanical stabilisation for extensive lesions in the sacrum are particularly challenging in tumour surgery. Despite radiological failure in 7/8 instrumented stabilisations, patients were relatively asymptomatic and only 1/8 required revision stabilisation surgery. Ethics approval:. None: Audit.

Royal Liverpool University Hospital, Liverpool, UK. To retrospectively review outcomes in patients who underwent vertebroplasty in Liverpool in response to recent level 1 publications claiming vertebroplasty to be no better than sham procedure assessed using 2 criteria. We reviewed cases between 2006 and 2009 looking at 5 criteria for procedure. Visual Analogue Score (VAS). Oswestry disability index scores (ODI). 96 patients identified. 10 patients excluded (inadequate data recorded) (n=86). Operated levels n=134 (thoracic n=61, lumbar n=71, sacral n=2). Presenting symptoms included back pain (86/86) and point tenderness was present in 90% (77/86). Average length of symptoms was 11.50 months with 28% reporting greater than 12 months. 72% recalled definite onset of symptoms with 90% being associated with a low velocity injury. Radiological findings showed an average of 54% height collapse and 91% showing high signal on STIR MRI sequences. Number of levels operated – 3 or more (n=9 VAS 5.3 ODI 10.6); 1 to 2 levels (n= 77 VAS 3.7 ODI 13.9). Average improvement in VAS score was 3.8.and ODI 13.6. 47% (40/86) of patients met all 5 current criteria recommended for operation (VAS 3.7, ODI 14). 53% (46/86) of patients met 2-5 criteria (VAS 3.8, ODI 13.4). There was improvement in pain scores in 91% of patients with an average pre-op VAS 7.8 and post-op VAS 4.0. There was no significant difference in patients meeting all 5 criteria compared to those meeting 2-5 criteria

Objective. To evaluate functional and oncological outcomes following sacral resection. Methods. Retrospective review of 97 sacral tumours referred to spinal or oncology units between 2004 and 2009. Results. 61 males, 37 females (average age of 47 (range 3 – 82). Average duration of symptoms 13 months. 17 metastatic disease, excluded from further discussion. Of the remainder 36/81(44%) underwent surgery – 21 excision, 9 excision and instrumented stabilisation, and 6 curettage. 13(16%) patients were inoperable - 8 advanced disease, 3 unable to establish local control, 2 recurrence. Colostomy was performed in 11/21(52%) patients who underwent excision. Deep wound infections in 6/21(29%). No difference in infection rates between definitive surgery with or without colostomy – 3/11(27%) vs. 3/10(30%). In the instrumented group, no colostomies were performed due to concerns about deep infection and none resulted (0/9). Radiological failure of stabilisation was noted in 7/9(78%). However, functionally, 3/9(33%) were mobilising independently, 3/9(33%) crutches, 2/9(22%) able to transfer and 1/9(11%) undocumented. Mean follow-up 25 months (range 0-70). Local recurrence in 9/36(25%) of operated patients. Metastasis occurred in 4/36(11%) and mortality 8/36(22%) although follow-up period was noted to be short. Conclusions. Results are comparable with current literature. Mechanical stabilisation for extensive sacral lesions is challenging. Despite radiological failure in 7/9 instrumented stabilisations, patients were relatively asymptomatic and only 1/9 required revision stabilisation surgery. By design none had colostomies and there were no deep infections

Purpose. To question the reliability of Thoracic Spine pain as a red flag and symptoms of a possible cause of Serious Spinal Pathology (SSP). Methods. The clinical notes and Magnetic Resonance Imaging (MRI) results of patients presenting to the Sheffield Spinal Service with Thoracic spine symptoms but no signs were retrospectively reviewed over the period of 2 year (September 2008-August 2010). The clinical reason for request of Thoracic MRIs were noted and the patient notes were reviewed to determine their presentation, length of time of symptoms, age and also it was noted whether any other recognized red flag symptoms were present. Exclusion criteria consisted of patients referred with known SSP or myelopathic symptoms. Results. 57 thoracic spine MRI requests were made in total by the orthopaedic spinal teams for patients presenting with thoracic spine pain in the time period. 8 patients were excluded as per criteria as they were referred with known SSP as were 4 other patients with a history of previous cancer. 45 patients presented with thoracic spine pain but no other red flag signs or symptoms of these none had MRI evidence of serious spinal pathology or indeed anything pathological indicating the cause of their symptoms. Conclusion. The majority of those presenting to orthopaedic spinal clinic with thoracic spine pain alone with no other red flag signs have no pathological cause. Thoracic pain is a widely accepted indicator (red flag) of potential serious spinal pathology. The findings from this review would not support thoracic pain alone as an indicator of SSP

Primary malignant tumours of the sacrum are rare, arising from bony or neural elements, or bone marrow in haematological malignancies. Management of these lesions is dictated by anatomical considerations and the behaviour of tumours. The three key issues which arise are the adequacy of tumour resection, mechanical stabilisation and the need for colostomy. A retrospective review of the surgical management of primary malignant sacral tumours from 2004 - 2009. The study included 46 patients (34 males, 12 females) with an average age of 49 (range 7 – 82). Median duration of symptoms before presentation was 26 months. 10 patients had inoperable tumours at presentation. 6 patients had chemotherapy. 2 patients opted for palliative radiotherapy. 1 patient was unfit for surgery. 25 patients (54%) underwent surgical resection. 8 underwent instrumented stabilisations with fibula strut graft vs. 17 uninstrumented. Colostomy was performed in 10 patients (40%). Mean follow post-operatively was 19.0 months. Wound healing problems were present in 5/25 (20%). There was no difference in infection rates between definitive surgery with and without colostomy. Mechanical failure of stabilisation was noted in 75%. There was one peri-operative death. Local recurrence occurred in 12%(3/25) of operated patients although follow-up period was noted to be short. Mechanical stabilisation for extensive lesions in the sacrum are particularly challenging in tumour surgery. Despite radiological failure in 7/8 instrumented stabilisations, patients were relatively asymptomatic and only 1/8 required revision stabilisation surgery.

Introduction:. Scheuermann's kyphosis is a fixed round back deformity characterised by wedged vertebrae seen on radiograph. It is known patients presented with a negative sagittal balance before operation. Few studies investigated the outcome after operation, especially the change in the lumbar hyperlordosis. Aim:. To investigate the change in sagittal profile after correction surgery. Method:. This is a retrospective review of cases from 2001 to 2012. Our centre uses a posterior, four rod cantilever reduction technique for all Scheuermann's Kyphosis correction. 36 cases are identified. They include 24 males and 12 females with an average age of 20 and follow up of 27 months. First 8 cases used the stainless steel hybrid implants. The remaining 28 had titanium all pedicle screw system. All had intra-operative spinal cord monitoring. Results:. The target of thoracic kyphosis correction is around the accepted upper end of normal limit (40°). The average thoracic kyphosis Cobb angle was 78.5°. The immediate post-op angle was 43.2° and at final follow up, 43.6°. The average lumbar lordosis changed from 65.7° pre-op to 48.8° post-op, which is now bigger than the thoracic kyphosis. The result is the transfer of average sagittal balance (C7 plumb line) from −2.2 cm to −3.5 cm, which remains posterior to the posterior corner of S1 after the surgery. Discussion:. Surgery can improve the roundback deformity but not the overall sagittal profile. We have no explanation to this phenomenon. This could imply the pathology of Scheuermann's Kyphosis involves the whole spine, not just the wedging thoracic segment. Conflict Of Interest Statement: No conflict of interest

Purpose. To report the results of full vertebral column resection (VCR) for paediatric spinal deformity. Methods and Results. All VCR (n=47) for paediatric spinal deformity were retrospectively evaluated from four university hospitals performing these procedures in Finland between 2005 and 2010. After excluding single hemivertebra (n=25) and resections performed for patients with MMC (n=6), 16 patients with full VCR (mean age at surgery 12.9 yrs [6.5-17.9] AIS 1; NMS 3; Congenital scoliosis 3 primary, revision 4; Kyphosis congenital 2, global 2; NF1 scoliosis 1) were identified. Seven procedures were performed anteroposteriorly and nine posterior-only. Mean follow-up time 1.9 (0.6–5.5) years. Major Curve (MC) averaged preoperatively 85 (58–120) degrees, 31 (14-53) degrees at 6 months, and 37 (17-80) degrees at 2-year follow-up. MC correction averaged 61 (46-86)% in the AP and 64 (57-83)% in the PL group at 6 months and 54 (18-86)% and 60 (41-70)% at 2-yr FU, respectively (NS). Blood loss averaged 3400 (500-8200) mL (NS between groups). The mean SRS-24 total scores were 100 (92-108) for AP and 102 (95-105) for PL group. There was one paraparesis in the AP group necessitating urgent re-decompression with full recovery. One peripheral L5 motor deficit resolved fully within few days (PL). Two junctional kyphosis were observed (one in both group). One one-sided partial lower instrumentation pull-out was observed without need for revision. One pseudoarthrosis occurred in AP group needing revision. Conclusions. Full VCR is rarely needed for paediatric spinal deformity with an estimated incidence of 2.9/million/year. Posterior VCR allows better control of neural elements during deformity correction

Objectives. This paper describes the outcomes obtained from a 12 hour group based multidisciplinary functional restoration programme for patients with persistent low back pain who presented with psychosocial obstacles to recovery. The programme was designed to address modifiable psychosocial obstacles to recovery over a four week period, reduce pain related disability, improve pain self-efficacy and reduce patients' reliance on analgesic medication. Design. A single group retrospective analysis. Participants. Data from 54 participants with non-specific low back pain (Male = 26. Female =28, mean age 43.7yrs) who attended a four week functional restoration programme between September 2012 and June 2013 were analysed. Results. There was a statistically significant improvement between Oswestry Disability Index and Pain Self Efficacy scores before and after the treatment intervention, and at 9 month follow-up (p<0.001). When only scores at the end of the treatment intervention and month 9 were compared there was no significant difference (p=0.184 for ODI, p=0.341 for PSEQ). Patients also self-reported reduced reliance on analgesic medication after the treatment intervention and at 9 month follow-up. Conclusion. The findings indicate that a group based multidisciplinary functional restoration programme for patients with persistent low back pain, which targets modifiable obstacles to recovery, can be effective in reducing disability, improving self-efficacy and reducing reliance on medication in both the short and medium term.

Purpose of Study/Background

To identify whether patients were satisfied with the overall educational component of the specialist nurse (CNS)/occupational therapist (OT) led pre-operative assessment clinic in order to identify areas which required improvement.

The pre-operative specialist nurse led clinic was set up in 2002. The aim was to provide high quality information to patients undergoing elective spinal surgery in order to manage expectations and optimise post-operative recovery. Initially the clinic was specialist nurse led however, in 2006 occupational therapy input was introduced in order to provide an increased depth of information in regard to function and activities of daily living post operatively. In addition this has allowed assistive equipment to be provided pre-operatively. The format of this clinic has enhanced the patient's journey by facilitating reduced length of stay and more timely discharge.

The purpose was to analyze preoperative symptoms, curve characteristics, and outcome of surgery in patients operated on for isthmic spondylolisthesis with concomitant scoliosis. Overall, 151(9.1%) of 1667 scoliosis patients had spondylolisthesis treated surgically in 21 (13.9%)(19 females, 2 males; 11 low-, 10 high-grade). Patients' age at admission was 13.5(10-17)y. Preoperatively, 5/21 were pain-free (1 high-grade, 4 low-grade), 7 (2 high-grade) had LBP, 2 (both high-grade) radiating pain, and 7 (5 high-grade) had both. Hamstring tightness was present in 5/10 high-grades. Scoliosis was primary thoracic in 3/11 low-grade and secondary lumbar with oblique rotated take-off of L5 in 8/11 low-grade patients. Of the high-grades, 7/10 had sciatic curves and 3 secondary lumbar. In low-grades, the main indication for surgery was pain in 3/11 and lumbar curve progression or the intent to prevent it in 7/11. The operative technique was uninstrumented posterolateral fusion in 8/11, instrumented L4-S1 fusion with reduction of L4-tilt in 2, and direct repair in 1 patient. High-grades were fused to prevent further slipping regardless of subjective symptoms (uninstrumented anterior 5, combined 2, instrumented reduction 3). Selective thoracic fusion for scoliosis was performed in 3 patients. None of the lumbar curves needed fusion. All sciatic curves resolved. The follow-up time was 10.6(2-21)y. Of the low-grade patients, 5 were pain-free, 4 had moderate pain, and 2 had a severe chronic pain syndrome. One had broken pedicle screws without sequelae. Of the high-grade patients, 4 were pain-free, 6 had moderate pain. One had a pain-free peroneal weakness after slip reduction.

To evaluate Radiological changes in the lumbosacral spine after insertion of Wallis Ligament for Foraminal Stenosis.

Thirty two Levels in Twenty Six patients were followed up with standardised radiographs after insertion of Wallis Ligaments for Foraminal Stenosis. Wallis ligaments as a top-off or those with prolapsed discs were not included. The Radiological parameters compared were Anterior and Posterior Disc height, Foraminal height and width, The inter-vertebral angle (IVA), Lumbar lordosis and Scoliosis if any. The presence of slips and their progression post-op was noted, as was bony lysis if any.

There were ten males with thirteen levels and sixteen females with nineteen levels in the study. Eighteen levels (56.25%) were L4/L5, ten (31.25%) were L5/S1 and 4 (12.5%)were L3/L4. The average age in the series was 59.6 years (Range 37 – 89 yrs). Average follow up was 9.5 months (Range 2 to 36). The Average increase in Anterior disc height was 1.89 mm (+/−1.39), the posterior disc height increased by an average 1.09 mm (+/−1.14). Foraminal height increased by an average 3.85 mm (+/− 2.72), while foraminal width increased by 2.14 mm (+/− 1.38). The IVA increased in 16 and reduced in 15 patients, with no change in 1. Lumbar Lordosis increased in 23 patients, with an average value of 2.3°. No patient exhibited progression in scoliosis and no lysis could be identified. There were three Grade I slips pre-op; none progressed.

Foraminal dimensions and Disc height were consistently improved after Wallis insertion. Changes in IVA and Lumbar lordosis were however variable. A longer follow up is suggested to look for sustained improvement and the presence of lysis.

Aims. The escalating demand for medical resources to address spinal diseases as society ages is an issue that requires careful evaluation. However, few studies have examined trends in spinal surgery, especially unscheduled hospitalizations or surgeries performed after hours, through large databases. Our study aimed to determine national trends in the number of spine surgeries in Japan. We also aimed to identify trends in after-hours surgeries and unscheduled hospitalizations and their impact on complications and costs. Methods. We retrospectively investigated data extracted from the Diagnosis Procedure Combination database, a representative inpatient database in Japan. The data from April 2010 to March 2020 were used for this study. We included all patients who had undergone any combination of laminectomy, laminoplasty, discectomy, and/or spinal arthrodesis. Results. This investigation included 739,474 spinal surgeries and 739,215 hospitalizations in Japan. There was an average annual increase of 4.6% in the number of spinal surgeries. Scheduled hospitalizations increased by 3.7% per year while unscheduled hospitalizations increased by 11.8% per year. In-hours surgeries increased by 4.5% per year while after-hours surgeries increased by 9.9% per year. Complication rates and costs increased for both after-hours surgery and unscheduled hospitalizations, in comparison to their respective counterparts of in-hours surgery and scheduled hospitalizations. Conclusion. This study provides important insights for those interested in improving spine care in an ageing society. The swift surge in after-hours spinal surgeries and unscheduled hospitalizations highlights that the medical needs of an increasing number of patients due to an ageing society are outpacing the capacity of existing medical resources.

Aims. The prevalence of scoliosis is not known in patients with idiopathic short stature, and the impact of treatment with recombinant human growth hormone on those with scoliosis remains controversial. We investigated the prevalence of scoliosis radiologically in children with idiopathic short stature, and the impact of treatment with growth hormone in a cross-sectional and retrospective cohort study. Methods. A total of 2,053 children with idiopathic short stature and 4,106 age- and sex-matched (1:2) children without short stature with available whole-spine radiographs were enrolled in the cross-sectional study. Among them, 1,056 with idiopathic short stature and 790 controls who had radiographs more than twice were recruited to assess the development and progression of scoliosis, and the need for bracing and surgery. Results. In the cross-sectional study, there was an unexpectedly higher prevalence of scoliosis (33.1% (681/2,053) vs 8.52% (350/4,106)) in children with idiopathic short stature compared with controls (odds ratio 3.722; p < 0.001), although most cases were mild. In the longitudinal study, children with idiopathic short stature had a higher risk of the development and progression of scoliosis than the controls. Among children with idiopathic short stature without scoliosis at baseline, treatment with growth hormone significantly increased the risk of developing scoliosis (p = 0.015) and the need for bracing (p < 0.001). Among those with idiopathic short stature and scoliosis at baseline, treatment with growth hormone did not increase the risk of progression of the scoliosis, the need for bracing, or surgery. Conclusion. The impact of treatment with growth hormone on scoliosis in children with idiopathic short stature was considered controllable. However, physicians should pay close attention to the assessment of spinal curves in these children. Cite this article: Bone Joint J 2023;105-B(4):439–448

Aims. To identify the incidence and risk factors for five-year same-site recurrent disc herniation (sRDH) after primary single-level lumbar discectomy. Secondary outcome was the incidence and risk factors for five-year sRDH reoperation. Methods. A retrospective study was conducted using prospectively collected data and patient-reported outcome measures, including the Oswestry Disability Index (ODI), between 2008 and 2019. Postoperative sRDH was identified from clinical notes and the centre’s MRI database, with all imaging providers in the region checked for missing events. The Kaplan-Meier method was used to calculate five-year sRDH incidence. Cox proportional hazards model was used to identify independent variables predictive of sRDH, with any variable not significant at the p < 0.1 level removed. Hazard ratios (HRs) were calculated with 95% confidence intervals (CIs). Results. Complete baseline data capture was available for 733 of 754 (97.2%) consecutive patients. Median follow-up time for censored patients was 2.2 years (interquartile range (IQR) 1.0 to 5.0). sRDH occurred in 63 patients at a median 0.8 years (IQR 0.5 to 1.7) after surgery. The five-year Kaplan-Meier estimate for sRDH was 12.1% (95% CI 9.5 to 15.4), sRDH reoperation was 7.5% (95% CI 5.5 to 10.2), and any-procedure reoperation was 14.1% (95% CI 11.1 to 17.5). Current smoker (HR 2.12 (95% CI 1.26 to 3.56)) and higher preoperative ODI (HR 1.02 (95% CI 1.00 to 1.03)) were independent risk factors associated with sRDH. Current smoker (HR 2.15 (95% CI 1.12 to 4.09)) was an independent risk factor for sRDH reoperation. Conclusion. This is one of the largest series to date which has identified current smoker and higher preoperative disability as independent risk factors for sRDH. Current smoker was an independent risk factor for sRDH reoperation. These findings are important for spinal surgeons and rehabilitation specialists in risk assessment, consenting patients, and perioperative management.
