Primary Total Knee Replacement using Rotating Hinge Implants in Poliomyelitis: A Case Series and Review of the Literature.

Introduction: The results of primary total knee replacement (TKR) using hinge implants performed in the Indian population with post-polio residual paresis (PPRP) are unknown. The purpose of this study was to report the outcome of primary rotating hinge TKR in Indian patients with PPRP at a minimum follow-up of 12 months. Materials and Methods: We retrospectively reviewed the clinical and radiological records of six patients treated with primary rotating hinge TKR. Pre-and post-operative (at final follow-up) knee range of motion (ROM), knee sagittal deformity, knee society score (KSS), and Oxford knee score (OKS) were compared to determine improvement in function. Results: Six rotating hinge TKRs (five female and one male patient) were analyzed for this study. At a mean follow-up of 27 ± 22 months (range, 12-71 months), the mean pre-operative KSS of 50.6 ± 2.5 significantly improved (P < 0.0001) to 72.5 ± 1.6, and the mean pre-operative OKS of 23.6 ± 1.6 significantly improved (P < 0.0001) to 35.3 ± 1.7. The mean pre-operative knee ROM of 94° ± 10° changed to 92° ± 4° (P = 0.64) and the mean pre-operative sagittal deformity of 7° ± 23.5° changed to -3° ± 2.5° (P = 0.32) at final follow-up. None of the knees had any intra- or post-operative complications or showed radiologic evidence of post-operative loosening, subsidence, or periprosthetic radiolucent lines at the final follow-up. Conclusion: Rotating hinge TKR gave excellent clinical and radiological results at a mean follow-up of 27 months in the present study. Despite TKR being a technically challenging procedure in patients with poliomyelitis-affected limbs, a rotating hinge design, along with meticulous surgical technique, can significantly improve function in such patients.

Finite element analysis of implanted lumbar spine: Effects of open laminectomy plus PLF and open laminectomy plus TLIF surgical approaches on L3-L4 FSU.

Several finite element (FE) studies reported performances of various lumbar fusion surgical approaches. However, comparative studies on the performance of Open Laminectomy plus Posterolateral Fusion (OL-PLF) and Open Laminectomy plus Transforaminal Interbody Fusion (OL-TLIF) surgical approaches are rare. In the current FE study, the variation in ranges of motions (ROM), stress-strain distributions in an implanted functional spinal unit (FSU) and caudal adjacent soft structures between OL-PLF and OL-TLIF virtual models were investigated. The implanted lumbar spine FE models were developed from subject-specific computed tomography images of an intact spine and solved for physiological loadings such as compression, flexion, extension and lateral bending. Reductions in the ROMs of L1-L5 (49 % to 59 %) and L3-L4 implanted FSUs (91 % to 96 %) were observed for both models. Under all the loading cases, the maximum von Mises strain observed in the implanted segment of both models exceeds the mean compressive yield strain for the vertebra. The maximum von Mises stress and strain observed on the caudal adjacent soft structures of both the implanted models are at least 22 % higher than the natural spine model. The findings indicate the risk of failure in the implanted FSUs and higher chances of adjacent segment degeneration for both models.

Occupation-based demographic, clinical, and psychological presentation of spine pain: A retrospective analysis of 71,727 patients from urban India.

BACKGROUND: Although many studies have investigated the physical and ergonomic risks of spine pain in specific occupation groups, the literature is lacking on occupation-based clinical and psychological presentation in patients with spine pain. OBJECTIVE: To analyze occupation-based variation in demographic, clinical, and psychological presentation in patients with spine pain. METHODS: This retrospective study analyzed the clinical data of 71727 patients with spine pain visiting a chain of spine rehabilitation clinics. Demographic and clinical variables such as gender, age, affected site, symptom duration, clinical symptoms and presentation, pain intensity, disability, and STarT Back Screening Tool (SBT) risk were compared between 9 occupational groups. RESULTS: The service and sales workers (44%) and students (43.5%) groups had the highest percentage of patients who presented with central spine pain; military personnel had the highest percentage of patients who presented with unilateral radicular pain (51.5%); and the retired or unemployed group had the highest percentage of patients who presented with severe myotomal loss (grade≤3) (6%). Homemakers had significantly higher pain intensity and disability (p < 0.001) and had the highest percentage of patients who presented with severe pain (47%), severe and crippled disability (59.5%), and medium to high risk (59%) with SBT when compared to other occupational groups. CONCLUSION: Patients with spine pain showed variation in demographic, clinical, and psychological presentation based on their occupation. The findings of this study can be the basis for identifying risk factors for spine pain and helping plan preventive and treatment measures based on their occupation.

Finite Element Analysis Comparing the Biomechanical Parameters in Multilevel Posterior Cervical Instrumentation Model Involving Lateral Mass Screw versus Transpedicular Screw Fixation at the C7 Vertebra.

STUDY DESIGN: Basic research. PURPOSE: This finite element (FE) analysis (FEA) aimed to compare the biomechanical parameters in multilevel posterior cervical fixation with the C7 vertebra instrumented by two techniques: lateral mass screw (LMS) vs. transpedicular screw (TPS). OVERVIEW OF LITERATURE: Very few studies have compared the biomechanics of different multilevel posterior cervical fixation constructs. METHODS: Four FE models of multilevel posterior cervical fixation were created and tested by FEA in various permutations and combinations. Generic differences in fixation were determined, and the following parameters were assessed: (1) maximum moment at failure, (2) maximum angulation at failure, (3) maximum stress at failure, (4) point of failure, (5) intervertebral disc stress, and (6) influence of adding a C2 pars screw to the multilevel construct. RESULTS: The maximum moment at failure was higher in the LMS fixation group than in the TPS group. The maximum angulation in flexion allowed by LMS was higher than that by TPS. The maximum strain at failure was higher in the LMS group than in the TPS group. The maximum stress endured before failure was higher in the TPS group than in the LMS group. Intervertebral stress levels at C6-C7 and C7-T1 intervertebral discs were higher in the LMS group than in the TPS group. For both models where C2 fixation was performed, lower von Mises stress was recorded at the C2-C3 intervertebral disc level. CONCLUSIONS: Ending a multilevel posterior cervical fixation construct with TPS fixation rather than LMS fixation at the C7 vertebra provides a stiff and more constrained construct system, with higher stress endurance to compressive force. The constraint and durability of the construct can be further enhanced by adding a C2 pars screw in the fixation system.

Post-surgical Pyoderma Gangrenosum after Total Knee Arthroplasty: A Rare Case Report and Literature Review.

Introduction: Pyoderma gangrenosum (PG) following a primary total knee arthroplasty (TKA) surgery is extremely rare, with very few cases reported in the literature. Case Report: We report our clinical experience of a 65-year-old female who developed PG following a primary TKA surgery. Corticosteroids and local wound care with vacuum-assisted closure dressing helped achieve rapid improvement in the wound condition. Conclusion: Post-surgical PG in TKA can be challenging with limited evidence for its definitive treatment. A high degree of suspicion and a multidisciplinary management approach will help in the timely diagnosis and optimization of treatment for this condition.

Sexual activity at 1 year after total hip arthroplasty in Indian patients.

PURPOSE: This study aimed to report changes in sexual activity and related difficulties and concerns among Indian patients at the end of 1-year after primary total hip arthroplasty (THA). MATERIALS AND METHODS: A detailed questionnaire related to sexual difficulty, frequency, position, satisfaction, stress, and concerns pre- and postoperatively was administered through an in-person interview at 1-year post-THA. RESULTS: Preoperatively, 77% of patients reported difficulties in sexual activities, which reduced significantly (p < 0.0001) to 30% at the end of 1-year post-operatively. A majority of patients reported no change in the frequency (56.5%) or satisfaction with their sexual activity (54%), and moderate to severe stress (53%) related to sexual activity at 1 year postoperatively. A significantly higher percentage (p = 0.01) of female patients (63%) reported changing their coital position postoperatively due to difficulty in leg positioning when compared to male patients (37.5%). Most patients (69%) were not able to procure information on sexual activity after THA surgery. and only 17.5% of patients discussed the topic with their surgeon. CONCLUSION: Although THA significantly reduced difficulty in sexual activity, most patients reported no change in the frequency of sexual activity or sexual satisfaction, had moderate to severe stress regarding sex, and were primarily concerned about safety of coital position and fear of dislocation at the end of 1-year postoperatively. Pre- and postoperative counselling by their surgeons will provide the patient with relevant information and help reduce anxiety and stress, improve satisfaction, and enhance the overall sexual health of the patient undergoing primary THA.

Frozen shoulder after COVID-19 vaccination versus idiopathic frozen shoulder: similar clinical features and functional improvement at 1-year follow-up.

Background: Frozen shoulder after COVID-19 vaccination is sparsely discussed in the medical literature. We aimed to evaluate: (1) the differences in the baseline clinical features and functional outcomes of conservatively treated frozen shoulder following COVID-19 vaccination compared to idiopathic frozen shoulder (2) the improvements in pain scores, functional outcomes, and range of motion (ROM) at 6-10 months and at 1 year of follow-up in patients with frozen shoulder after COVID-19 vaccination treated by conservative therapy. Methods: Between June 2021 and December 2021, 12 patients (13 shoulders) that were diagnosed with frozen shoulder after COVID-19 vaccination (vaccine related frozen shoulder [VRF] group) (final follow-up of 12.4 months ± 0.8 months) were compared with 20 patients that were diagnosed as idiopathic frozen shoulder unrelated to vaccination (unvaccinated frozen shoulder [UFS] group) (average follow-up of 13.4 ± 3.1 months). All patients were treated with home-based stretching exercises. Four (33%) patients in the VRF group and 15 (75%) patients in the UFS group underwent steroid injection in the suprascapular notch by an experienced radiologist. Results: The left side was affected more frequently in the VRF group [n = 10 (83.3%)] than in the UFS group [n = 8 (40%), P = .03]. The VRF and the UFS groups were similar in the rest of the baseline clinical features, such as the age distribution, men/women ratio, baseline Oxford Shoulder Scores (OSS), ROM deficit, and pain visual analogue scale (VAS) scores. The OSS, VAS pain scores, and the ROM deficit significantly improved in the VRF group at the 6-10-month follow-up and then at the final (12.4 ± 0.8 months) follow-up compared to the baseline values. At the final follow-up, there were no significant differences in the average external rotation, external rotation deficit, elevation, elevation deficit, internal rotation, pain VAS scores, and OSS between the VRF and the UFS group. Conclusion: To conclude, frozen shoulder following COVID-19 vaccination may present with clinical features similar to those of the idiopathic frozen shoulder. Furthermore, the patients with frozen shoulder following COVID-19 vaccination may continue to improve over one year with conservative treatment; the final improvements in function and ROM are similar to those with idiopathic frozen shoulder.

Do Improved Trunk Mobility and Isometric Strength Correlate with Improved Pain and Disability after Multimodal Rehabilitation for Low Back Pain?

Objective To determine the correlation between posttreatment trunk range of motion (ROM) and isometric strength (TIS) and pain and disability in patients who underwent multimodal rehabilitation for low back pain (LBP). Methods In this prospective cohort study, 122 patients undergoing multimodal rehabilitation for LBP were analyzed. The pre- and posttreatment numerical pain rating scale (NPRS) and the Oswestry disability index (ODI) scores, as well as trunk ROM and TIS were compared. The Pearson correlation was used to determine correlation between posttreatment clinical outcomes and ROM and TIS. Results At the end of treatment, the mean NPRS ( p < 0.0001) and ODI ( p < 0.0001) scores, mean trunk extension ( p < 0.0001), and flexion ( p < 0.0001) ROMs improved significantly. Similarly, posttreatment, the mean extension ( p < 0.0001) and flexion ( p < 0.0001) TISs improved significantly. There was a weak correlation between the NPRS score and ROM extension (r = -0.24, p = 0.006) and flexion strength (r = -0.28, p = 0.001), as well as between the ODI score and TIS extension (r = -0.30, p = 0.0007) and flexion (r = -0.28, p = 0.001). Conclusion Despite significant improvement in pain, disability, trunk ROM, and TIS with multimodal treatment, there was a weak correlation between posttreatment pain and function and trunk ROM and TIS. Improvement in pain and function with physical rehabilitation treatment for LBP is a complex phenomenon and needs further investigation.

Improvement in pain and function with physical rehabilitation treatment for LBP is a complex phenomenon and needs further investigation.

Resumo Objetivo Determinar a correlação entre a amplitude de movimento (ADM) do tronco pós-tratamento e a força isométrica do tronco (FIT) e a dor e a incapacidade em pacientes submetidos à reabilitação multimodal para dor lombar (DL). Métodos Neste estudo de coorte prospectiva, 122 pacientes submetidos à reabilitação multimodal para DL foram analisados. Foram comparados os escores de escala numérica de dor pré- e pós-tratamento (END) e do índice de incapacidade Oswestry (Oswestry disability index - ODI), a ADM do tronco e a FIT. A correlação de Pearson foi utilizada para determinar a correlação entre desfechos clínicos e a ADM e a FIT pós-tratamento. Resultados Ao final do tratamento, as médias de ADM (p< 0,0001) e ODI (p< 0,0001), as ADMs médias de extensão (p< 0,0001) e a flexão (p< 0,0001) do tronco melhoraram significativamente. Da mesma forma, a FIT pós-tratamento, as FITs médias de extensão (p< 0,0001) e flexão (p< 0,0001) melhoraram significativamente. Houve uma correlação fraca entre o escore do END e a ADM de extensão (r = -0,24, p= 0,006) e força de flexão (r = -0,28, p= 0,001) pós-tratamento, assim como entre o escore de ODI e FIT de extensão (r = -0,30, p= 0,0007) e flexão (r = -0,28, p= 0,001) pós-tratamento. Conclusão Apesar da melhora significativa da dor, capacidade, ADM do tronco e FIT com tratamento multimodal, houve uma fraca correlação entre dor pós-tratamento e função e ADM e FIT de tronco. A melhora da dor e da função com o tratamento de reabilitação física para DL é um fenômeno complexo e precisa de uma investigação mais aprofundada.

Effects of glenohumeral corticosteroid injection on stiffness following arthroscopic rotator cuff repair: a prospective, multicentric, case-control study with 18-month follow-up.

BACKGROUND: This study aimed to analyze the efficacy of single-dose corticosteroid injection (CSI) administered at 6 weeks postoperative to treat stiffness following arthroscopic rotator cuff repair (ARCR). METHODS: In this prospective, multicentric, case-control study, post-ARCR stiffness at 6 weeks was treated with either a single dose of intra-articular CSI (CSI group) or physical therapy with oral analgesics (non-CSI group). Pain intensity according to visual analog scale (VAS), functional outcome using the Constant Murley Shoulder Score, time to return to activities of daily living (ADLs), and retear rate were recorded at 6 weeks, 9 weeks, 12 weeks, 6 months, 12 months, and 18 months postoperatively in both groups. RESULTS: A total of 149 patients (54.5%) in the CSI group and 124 patients (45.5%) in the non-CSI group were included in this study. Pain and function were significantly better in the CSI group at 9-week, 12-week, and 6-month (P<0.001) follow-up, whereas they were not significantly different when the groups were compared at 12- and 18-month follow-up. The mean duration to return to ADLs was significantly shorter (P<0.001) in the CSI group. The incidence of retears was not significantly different (P=0.36) between groups at the end of 18 months of follow-up. CONCLUSIONS: Single-dose intra-articular CSI administered at 6 weeks postoperative to treat post-ARCR stiffness significantly improved pain, function, and duration of return to ADLs without increasing the risk of retears compared to patients who did not receive intra-articular CSI.

Biomechanical analysis of the novel S-type dynamic cage by implementation of teaching learning based optimization algorithm - An experimental and finite element study.

Anterior Cervical Discectomy and Fusion (ACDF) is the most popular and effective procedure for patients with intervertebral disc degeneration, where the degenerated disc is replaced with an interbody implant (widely known as cage). The design of the cage plays a vital role since it has to provide stability for the anterior cervical column without any side-effects. We designed a novel S-type dynamic cage for C4-C5 level, using Polyetheretherketone (PEEK) material considering four different shapes namely: square, circle, rectangle and elliptical, for the central window to occupy bone graft. The major design constrain for a successful cage is minimized cage stress, in order to avoid subsidence. Finite Element (FE) analysis results revealed that the cage stress values obtained during the physiological motion varied depending upon the shape of the central window provided for bone graft. The objective of this study is to optimize the central window shape using the Teaching Learning Based Optimization (TLBO) algorithm. It was found that square and elliptical shape bone graft cavity resulted in better outcomes. Additional experimental study was also conducted with a six-axis spine simulator. Based on the optimization results, we manufactured two PEEK cage models with square and elliptical shaped central window using additive manufacturing. A prototype model of the C4-C5 level made of Polyvinylchloride (PVC) was used for experiment due to the existing constraints for using a cadaveric model. The experimental results were cross-verified using FE analysis. Thus, we would like to conclude that square and elliptical shape of the central window were the better design factor for our novel dynamic cage.

Primary constrained condylar knee arthroplasty in severe varus deformity: a prospective 5-year functional follow-up study in Iraqi patients.

PURPOSE: The outcomes of the constrained condylar knee (CCK) implant used during primary total knee arthroplasty (TKA) in knees with severe varus in patients from low- and middle-income countries (LMICs) such as Iraq are not known. Hence, this study aimed to analyze and report the functional outcome of CCK TKA in patients with severe varus deformities at the end of 5 years in Iraqi patients. METHODS: In this prospective study, pre- and post-operative (at the end of 5 years) clinical outcome using Knee Society Score (KSS) and radiological deformity using hip-knee-ankle (HKA) angle was analyzed in 76 CCK TKAs (20 bilateral and 36 unilateral TKAs) performed in 56 patients with severe varus deformity (> 15°). RESULTS: At a mean follow-up of 60.3 months (range 60-68 months), the mean preoperative KSS knee score of 6.6 ± 4.5 improved significantly (p < 0.0001) to 87.2 ± 6.6 and the mean preoperative KSS function score of 7.1 ± 6.4 improved significantly (p < 0.0001) to 70.4 ± 7.8. The function score was good to excellent in 64.3% (36 patients), fair in 28.5% (16 patients), and poor in 7.1% (4 patients) at the end of 5 years. The mean preoperative HKA angle significantly improved (p < 0.001) from 25.5° ± 6° varus (range 17°-37°) to 3° ± 2.5° varus (range 0°-7.5°) at final follow-up. CONCLUSION: The CCK implant significantly improved pain and function in patients with severe varus deformity at the end of 5 years. The CCK implant is a good option during primary TKA in severe varus knees in patients from LMICs and can help achieve clinical outcomes similar to patients from high-income countries.

Changes in standing and walking time after multimodal physical rehabilitation in low grade degenerative lumbar spondylolisthesis: a non-randomised pilot study.

BACKGROUND: Surgery is often prescribed to patients with significant reduction in standing time (ST) and walking time (WT) due to degenerative lumbar spondylolisthesis (DLS). The efficacy of a multimodal physical rehabilitation protocol (MPRP) in improving ST and WT in patients with DLS is not known. OBJECTIVE: To investigate the effect of MPRP on ST and WT in patients with DLS and compare the results with similar patients treated with other physiotherapy treatment (OPT) methods. METHODS: Outcomes including numerical pain rating scale (NPRS) and Oswestry disability index (ODI) scores, ST and WT were compared in patients in the MPRP and OPT groups. RESULTS: Data from 25 patients in MPRP group and 10 patients in OPT group were analyzed. In the MPRP group, the mean NPRS and ODI scores, ST, and WT improved significantly (p < .0001) after MPRP at a mean follow-up of 328 days. The mean NPRS score was significantly lower (p = .0001); mean ST (p = .03), and mean WT (p = .03) were significantly higher; and the mean NPRS improvement (p < .0001), mean ST improvement (p = .001), and mean WT improvement (p = .008) were significantly higher in MPRP group when compared to the OPT group at final follow-up. CONCLUSION: Patients with low-grade DLS showed significant improvement in ST and WT after MPRP when compared to similar patients who underwent other physiotherapy treatments. These encouraging results indicate that MPRP can be utilized as a primary treatment option in patients with significantly reduced ST and WT due to DLS.

Comparison with Navigation of a Novel Three-Step Technique for Improving Accuracy of the Distal Femoral Resection during Conventional TKA: A Case-Control Study.

Correct placement of the femoral component in the coronal plane during primary total knee arthroplasty (TKA) is related to long-term survival. The aim of this radiographic study was to determine the accuracy of a novel three-step technique for improving the accuracy of the distal femoral cut during conventional technique and compare it with computer navigation during TKA. A total of 458 TKAs were retrospectively analyzed (178 conventional TKAs with the novel technique and 280 navigated TKAs) for postoperative femoral component coronal alignment and compared between the two groups. Mean femoral component coronal alignment was not significantly different (p = 0.314) between the two groups. There was no significant difference in the mean femoral component coronal alignment between varus and valgus knees. The number of outliers (90 ± 3 degrees) for femoral component coronal alignment was not significantly different between the two groups when assessed separately for varus and valgus deformities. The mean value of femoral component alignment using the conventional technique in knees with varus deformity <10 degrees was 88.8 degrees, in knees with varus deformity 10 to 20 degrees was 89.4 degrees, and in those with varus deformity >20 degrees was 90.2 degrees. Femoral component alignment in knees with varus <10 degrees was significantly different from those >20 degrees (p = 0.006); there was no significant difference between knees with varus <10 degrees and those with 10 to 20 degrees varus (p = 0.251), nor between 10 and 20 degrees varus knees and those with varus >20 degrees (p = 0.116). Using the novel three-step technique during conventional TKA to perform the distal femoral cut can help achieve femoral component coronal alignment comparable to the navigation technique.

Coracoid graft resorption after the Latarjet procedure does not depend on the preoperative glenoid defect.

BACKGROUND: The primary purpose was to compare coracoid graft resorption after the Latarjet procedure in patients without preoperative glenoid bone loss vs. those with more than critical glenoid loss. The secondary purposes were to compare the functional outcomes and to investigate the association of graft position, angle of the screws, preoperative glenoid defect, age at surgery, and smoking status with graft resorption. METHODS: Sixty consecutive patients with recurrent anterior instability were treated by the Latarjet procedure as the index procedure, irrespective of the glenoid bone loss between 2018 and 2021. Fifty-five patients were evaluated via computed tomography scans after a minimum of 1 year after surgery (range: 1-4 years). Twenty-five patients had no prior glenoid defect (No-defect group), 24 patients had preoperative glenoid defects ≥15% (Critical defect group), and 6 patients had glenoid defects between 5% and 15%. The No-defect group (n = 25) was compared with the Critical defect group (n = 24). Multivariate logistical regression was performed to evaluate the association of independent factors with the grade of resorption for all 55 patients in the cohort. RESULTS: Major graft resorption at the level of the superior screw was observed in 72%-84% of patients in the No-defect group (n = 25) and in 75%-83% of patients in the Critical defect group (n = 24) (P = 1, P = 1; no significant difference). No to mild resorption at the level of the inferior screw was observed in 96% of patients in the No-defect group and 100% of patients in the Critical defect group (P = 1; no significant difference). Postoperative Rowe scores (100 [95-100] vs. 100 [95-100]; P = .8) and shoulder subjective value (87 [11] vs. 86 [9]; P = .9) were not significantly different between the 2 groups. None of the independent factors, including the corresponding screw angle, the mediolateral graft positioning, prior glenoid defect, age, and smoking status, were associated with graft resorption in multivariate logistical regression. CONCLUSIONS: Graft resorption after the Latarjet procedure does not depend on the preoperative glenoid defect. The coracoid graft may be mostly resorbed around the superior screw but mildly or none at the level of the inferior screw, but this graft resorption is not dependent on the smoking status, age, prior glenoid defect, mediolateral graft positioning, and the angle of the screws.

Fear-Avoidance Beliefs, Kinesiophobia, and Disability Risk Among Indians with Spine Pain.

Purpose: To determine the burden of fear-avoidance beliefs (FAB), kinesiophobia, and risk of persistent disability among Indians with spine pain. Methods: Demographic and clinical data collected from 139 patients who attended a spine rehabilitation clinic for assessment and treatment of their spine pain were analyzed. Fear-avoidance beliefs, kinesiophobia, and risk of persistent disability were measured using the Fear-avoidance Beliefs Questionnaire (FABQ), Tampa Scale for Kinesiophobia (TSK), and the STarT Back Tool (SBT). A multivariate analysis was performed to determine the effect of pain, disability, age, gender, BMI, lifestyle, pain duration, and pain location on FAB, TSK, and SBT scores. Results: A majority of patients had medium to high-risk FAB-physical activities (FAB-P) (50.5%) and SBT (54%) scores. The percentage of patients with medium or high-risk FAB-P (p = 0.03), FAB-work (FAB-W) (p = 0.03), and SBT (p = 0.03) scores were significantly higher in patients with pain score > 7, and the percentage of patients with medium or high-risk with FAB-P (p < 0.0001), TSK (p = 0.0003), and SBT (p < 0.0001) scores were significantly higher in patients with severe, crippled or bed-ridden disability. Disability was the only significant predictor for FAB-W, FAB-P, and SBT scores. Conclusion: The prevalence of fear-avoidance beliefs and risk of persistent disability was significant among Indians and should be taken into account while planning treatment for their spine pain.

Prevalence and risk factors of neck pain in spine surgeons - Are we our own patients?

Aim: This survey of spine surgeons aimed to determine the prevalence of neck pain and identify the associated risk factors. The prevalence of neck pain has been reported in various medical sub-specialities including laparoscopy surgeons, dentists, plastic surgeons, ophthalmologist, urologist and orthopaedic surgeons. However, the literature is lacking on prevalence and risk factors for neck pain in spine surgeons. Methods: A survey questionnaire containing demographic, Neck pain and work practice details was administered to 300 spine surgeons (members of an online group) via text message and e-mail. Results: One hundred and eighty surgeons responded to the survey (response rate, 60%). Three spine surgeons had previous cervical spine surgeries. The 1-month prevalence rate of neck pain was 74.4% (134/180 surgeons). One hundred and eighteen surgeons (88%) reported only neck pain, 16 surgeons (11.9%) had neck pain with radicular arm pain. Only 20.5% of surgeons used a loupe, 18% of surgeons used a microscope, and 24% of surgeons used operating table height at umbilicus during surgery. There was no significant difference between the mean age (p = 0.65), work experience (p = 0.8), time spent in surgery (p = 0.7), and operating table height preference (p = 0.4) when symptomatic and asymptomatic groups were compared. However, a significantly greater percentage of surgeons had a sedentary lifestyle (p = 0.002) & used loupes as compared to microscopes (p = 0.04) in the symptomatic group. There was significant correlation between the surgeon's lifestyle & use of loupe and the incidence of neck pain. Conclusion: Spine surgeons have a higher prevalence of neck pain than general populations and surgeons from other specialties. Considering the high prevalence of neck pain, general health, work, and ergonomic guidelines and recommendations must be formulated to help prevent and decrease the burden of neck pain among spine surgeons.

Efficacy of telerehabilitation for spine pain during the Coronavirus pandemic lockdown: a retrospective propensity score-matched analysis.

PURPOSE: Despite increased usage of telemedicine to deliver treatment during the coronavirus disease 2019 (COVID-19) pandemic, the efficacy of telerehabilitation for spine pain is unknown. This study aimed to investigate the effect of telerehabilitation on pain and disability in patients with spine pain treated during the COVID-19 pandemic and compare the results to in-clinic rehabilitation. MATERIALS & METHODS: In this propensity score-matched analysis, 428 patients with spine pain who underwent telerehabilitation during the 6 months of COVID-19 pandemic lockdown and 428 patients who underwent in-clinic multimodal rehabilitation treatment during the 6-month period prior to lockdown were compared. Propensity score matching was done based on gender, age, pre-treatment pain, and disability. Post-treatment numerical pain rating scale (NPRS), Oswestry or Neck disability index (ODI or NDI), and minimal clinical important difference (MCID) achieved for NPRS and ODI/NDI scores were compared between the 2 groups. RESULTS: Post-treatment, the mean NPRS (mean difference - 1, p < 0.0001) and ODI/NDI (mean difference - 5.8, p < 0.0001) scores, were significantly lower in the telerehabilitation group when compared to control group. Similarly, the percentage of patients who achieved MCID of ≥ 2 for NPRS (mean difference - 6%, p = 0.0007) and MCID of ≥ 10 for ODI/NDI (mean difference - 7.5%, p = 0.005) scores were significantly higher in the telerehabilitation group. CONCLUSIONS: Telerehabilitation achieved significant reduction in pain and disability among patients with spine pain, better than in-clinic rehabilitation. These encouraging results during the COVID-19 pandemic indicate the need to further explore and test the efficacy and wider application of telerehabilitation for treating spine pain.IMPLICATIONS FOR REHABILITATIONTelerehabilitation can help achieve significant reduction in pain and disability among patients with spine pain.These encouraging results indicate the need to further explore a wider application of telerehabilitation for treating patients with spine pain during non-pandemic times.

Prevalence of low back pain in India: A systematic review and meta-analysis.

BACKGROUND: Although many studies have investigated the prevalence of low back pain (LBP) among Indian subjects, no meta-analysis has been conducted to determine the comprehensive epidemiological point, annual, lifetime prevalence of LBP among Indian subjects. OBJECTIVE: The purpose of this systematic review and meta-analysis was to investigate the point, annual, and lifetime prevalence of LBP in the Indian population. METHODS: We searched PubMed, Embase, Science Direct, and Cochrane Library databases for relevant studies that reported point, annual, or lifetime prevalence of LBP among Indian subjects. Pooled point, annual and lifetime prevalence rates were calculated. Meta-analysis, subgroup analysis, sensitivity analysis and publication bias assessment were performed. RESULTS: Ninety-seven studies were included in this review. Fifty-four studies included in the review (55.5%) were found to be of higher methodological quality. The pooled point, annual, and lifetime prevalence of LBP in India was 48% (95% CI 40-56%); 51% (95% CI 45-58%), and 66% (95% CI 56-75%), respectively. The pooled prevalence rates were highest among females, the rural population, and among elementary workers. CONCLUSION: The point, annual, and lifetime prevalence rates of LBP in the Indian population is higher compared to global and other ethnic populations affecting a large proportion of the population, especially among women, rural population and in elementary workers. The findings of this study can be the basis for formulating policy regarding the prevention and treatment of LBP in a large part of the global population.

Gender-based Variations in Trunk Motion and Isometric Strength in Young Adults with Low Back Pain: A Prospective Case-control Study.

Objective To determine gender-based variations in trunk range of motion (RoM) and isometric strength (IS) in symptomatic and asymptomatic young adults. Methods In this prospective case-control study, 73 subjects with low back pain (LBP) and 80 asymptomatic subjects were analyzed. Dynamometer-based device trunk RoM and IS measurements in extension, flexion, and rotation were compared in both groups and gender-based subgroups. Multivariate analysis was used to determine factors influencing trunk RoM and IS. Results Symptomatic males had significantly less extension RoM and extension, flexion, and rotation isometric trunk strength (ITS) ( p < 0.0001) compared with asymptomatic males, whereas no significant difference was found between asymptomatic and symptomatic females. However, the mean extension-flexion RoM and mean extension-flexion ITS ratios were significantly lower ( p = 0.04) in asymptomatic females compared with symptomatic females. Female gender was significantly associated with less extension and flexion ITS in both asymptomatic and symptomatic subjects. Conclusion Males with LBP had significant global ITS weakness when compared with asymptomatic males. Despite no significant ITS difference in symptomatic versus asymptomatic females, LBP caused significant extension-flexion RoM and ITS imbalance in females. These gender-based variations in trunk RoM and IS, especially the extensor-flexor IS imbalance in females, must be considered while designing rehabilitation treatment protocols for LBP.
