Examination of Pain, Quality of Life, Disability, and Anxiety in Patients Undergoing Lumbar Disc Surgery with and without COVID-19

Aim: This study aims to examine pain, disability, anxiety, and quality of life in patients undergoing lumbar disc herniation (LDH) surgery with and without COVID-19. Material and Method: Eighty patients who were diagnosed with LDH and planned surgery between March and September 2023 were included in the study. 50% of the patients were diagnosed with COVID-19 for at most six months, according to the positive polymerase chain reaction (PCR) test. 50% of the patients had no symptoms of COVID-19, ranging from mild to severe, and the PCR test was negative (-). The patients' pain level, disability, anxiety, and quality of life were evaluated and compared between the groups with and without COVID. Results: The mean scores of physical roles, physical function, mental health, body pain, and social function on the SF-36 quality of life scale in the LDH+COVID-19 (+) patient group were significantly lower than those in LDH+COVID-19 (-) (p

Construct validation of the Japanese Core Outcome Measures Index and the impact of diseases on patient-reported outcome measures in preoperative patients with lumbar spinal stenosis and disk herniation: a single-center observational study.

The primary objective was to validate the construct validity of the Japanese Core Outcome Measures Index (COMI) in preoperative patients aged 60years or older undergoing lumbar spine surgery for lumbar spinal stenosis (LSS) and lumbar disk herniation (LDH). Additionally, as a secondary aim, we explored the impact of these diseases on quality of life (QOL). The analysis included 199 preoperative patients aged 60 and above who were scheduled for lumbar spine surgery. To assess QOL, Japanese versions of the COMI, Oswestry Disability Index (ODI), EuroQol-5 Dimension-3 Level (EQ-5D-3L), and SF-12v2 were employed. The study assessed the validity of the COMI and compared demographic and clinical characteristics between the LSS (147 cases) and LDH (52 cases) groups. It used multivariate covariance analysis (MANCOVA) to examine the impact of diseases (LSS and LDH) on each patient-reported outcome measure while considering covariates. Compared to the LSS group, the LDH group showed more difficulty with the COMI summary score (LSS/LDH [mean]: 6.9/8.1, p < 0.001), ODI score (46.8/57.4, p < 0.001), and EQ-5D utility (0.53/0.43, p < 0.001). The LDH group also reported more difficulties in the COMI-function, COMI-symptom-specific well-being, COMI-disability, ODI-personal care, ODI-social life, and SF-12v2-bodily pain subscales. MANCOVA demonstrated that these results were not influenced by covariates such as gender and medical history. This study highlights the distinct impact of LSS and LDH on preoperative QOL in older patients undergoing lumbar spinal surgery. Tailored interventions are essential to address the specific challenges posed by these conditions and improve patient-centered outcomes and postoperative recovery.

Repeat Discectomy or Instrumented Surgery for Recurrent Lumbar Disk Herniation: An Overview of French Spine Surgeons' Practice.

Retrospective multicenter cohort study. Recurrent lumbar disc herniation (ReLDH) is a common condition requiring surgical intervention in a large proportion of cases. Evidence regarding the appropriate choice between repeat microdiscectomy (RD) and instrumented surgery (IS) is lacking. To understand the indications for either of the procedures and compare the results, we aimed to provide an overview of spine surgeon practice in France. This retrospective, multicenter analysis included adults who underwent surgery for ReLDHs between December 2020 and May 2021. Surgeons were asked which of the following factors determined their therapeutic choice: radio-clinical considerations, non-discal anatomical factors, patient preference, or surgeon background. Data on preoperative clinical status and radiologic findings were collected. Patient-reported outcome measures (PROMs) were assessed and compared using propensity scores preoperatively and at 3 and 12 months postoperatively. The study included 150 patients (72 IS and 78 RD). Radioclinical elements, anatomical data, patient preferences, and surgeon background influenced the choice of RD in 57.7%, 1.3%, 25.6%, and 15.4% of the cases, respectively, and IS in 34.7%, 6.9%, 13.9%, and 44.5% of the cases, respectively. At 12 months, patient satisfaction, return to work, and changes in PROMs were not significantly different between the groups. The decision-making process included both objective and subjective factors, resulting in patient satisfaction in 80.3% to 81.5% of cases, with significant clinical improvement in radicular symptoms in 75.8% to 91.8% of cases, and quality of life in 75.8% to 84.9% of cases, depending on the procedure performed.

Risk Factors for Surgical Treatment of Lumbar Degenerative Disc Disease in Middle-aged and Older Women: A Prospective Case-Control Study of 2370 Subjects.

Given the distinct physiological and societal traits between women and men, we propose that there are distinct risk factors for lumbar degenerative disc disease surgeries, including lumbar disc herniation (LDH) and lumbar spinal stenosis (LSS), in middle-aged and older populations. However, few studies have focused on middle-aged and older women. This study aims to identify these risk factors specifically in this population. In this case-control study, the study group comprised 1202 women aged ≥ 45 years who underwent operative treatment of lumbar degenerative disc disease (LDH, n = 825; LSS, n = 377), and the control group comprised 1168 women without lumbar disease who visited a health examination clinic during the same period. The study factors included demographics (age, body mass index [BMI], smoking, labor intensity, and genetic history), female-specific factors (menopausal status, number of deliveries, cesarean section, and simple hysterectomy), surgical history (number of abdominal surgeries, hip joint surgery, knee joint surgery, and thyroidectomy), and systemic diseases (hypercholesterolemia, hypertriglyceridemia, hyper-low-density lipoprotein cholesterolemia, hypertension, diabetes, cardiovascular disease, and cerebrovascular disease). Multivariate binary logistic regression analysis was used to calculate the odds ratio (OR) and 95% confidence interval (95% CI) of associated factors. The risk factors for surgical treatment of LDH in middle-aged and older women included BMI (OR = 1.603), labor intensity (OR = 1.189), genetic history (OR = 2.212), number of deliveries (OR = 1.736), simple hysterectomy (OR = 2.511), hypertriglyceridemia (OR = 1.932), and hyper-low-density lipoprotein cholesterolemia (OR = 2.662). For surgical treatment of LSS, the risk factors were age (OR = 1.889), BMI (OR = 1.671), genetic history (OR = 2.134), number of deliveries (OR = 2.962), simple hysterectomy (OR = 1.968), knee joint surgery (OR = 2.527), hypertriglyceridemia (OR = 1.476), hyper-low-density lipoprotein cholesterolemia (OR = 2.413), and diabetes (OR = 1.643). Cerebrovascular disease was a protective factor against surgery for LDH (OR = 0.267). BMI, genetic history, number of deliveries, simple hysterectomy, hypertriglyceridemia, and hyper-low-density lipoprotein cholesterolemia were independent risk factors for surgical treatment of both LDH and LSS in middle-aged and older women. Two disparities were found: labor intensity was a risk factor for LDH patients, and knee joint surgery and diabetes were risk factors for LSS patients.

Back morphology and walking patterns mean 13.8 years after surgery for lumbar disk herniation in adolescents.

In many pain conditions, there is lingering pain despite healed tissue damage. Our previous study shows that individuals who underwent surgery for lumbar disk herniation (LDH) during adolescence have worse health, more pain, and increased disk degeneration mean 13 years after surgery compared with controls. It is unclear if walking patterns segregate surgically treated LDH adolescents and controls at mean 13-year follow-up. Here, we analyzed the relationship between gait, back morphology and other health outcomes in a cohort of individuals treated surgically because of lumbar disk herniation compared with controls. We analyzed gait during a walking paradigm, back morphology at the site of surgery, and standardized health outcomes, among individuals who received surgery for LDH as adolescents, "cases" (n = 23), compared with "controls" (n = 23). There were gait differences in head (P = 0.021) and trunk angle (P = 0.021) between cases and controls in a direction where cases exhibited a posture associated with sickness. The gait variance was explained by subjective pain and exercise habits rather than objective disk degeneration. Over a decade after surgery for LDH during adolescence, health among cases is worse compared with controls. The head and trunk angles differ between cases and controls, indicating that the residual pain lingers and may cause changes in movement patterns long after a painful episode in early life. Gait may be a useful target for understanding maintenance of pain and disability among individuals treated surgically for LDH during adolescence.

Effect and complication among different kinds of spinal endoscopic surgery for lumbar disc herniation

To compare clinical efficacy and complication rate of percutaneous endoscopic transforaminal discectomy(PETD),percutaneous endoscopic interlaminar discectomy (PEID) and unilateral biportal endoscopic (UBE) in treating single-segment lumbar disc herniation(LDH). From October 2019 to August 2021,121 LDH patients with single-segment treated by spinal endoscopy were retrospectively analyzed and divided into three groups. In PETD group,there were 48 patients,including 19 males and 29 females,aged from 18 to 72 years old with an average of (44.0±13.9) years old;3 patients with L3,4 segments,27 patients with L4,5 segments,and 18 patients with L5S1 segments. In PEID group,there were 43 patients,including 23 males and 20 females,aged from 20 to 69 years old with an average of (40.1±12.1) years old;1 patient with L3,4 segments,15 patients with L4,5 segments,and 27 patients with L5S1 segments. In UBE group,there were 30 patients,including 12 males and 18 females,aged from 29 to 72 years old with an average of (41.2±15.0) years old;1 patient with L3,4 segments,18 patients with L4,5 segments,and 11 patients with L5S1 segments. Operation time,blood loss,fluoroscopy times and complications among three groups were observed and compared. Before opertaion,3 months after operation and at the latest follow-up,visual analogue scale (VAS) was used to evaluate low back pain and lower extremity pain,Oswestry disfunction index (ODI) was used to evaluate lumbar function,and modified MacNab was used to evaluate clinical efficacy at the latest follow-up. All patients were performed endoscopic spinal surgery completly and were followed up for at least 12 months. One patient occurred dural sac rupture both in PETD and PEID group,and dural sac rupture was small,and there was no obvious discomfort after operation. Two patients were occurred intraoperative rupture of dural sac in UBE group. One patient was occurred cerebrospinal fluid leakage after operation,and was improved after rest in supine position and fluid rehydration. One patient without no significant postoperative discomfort. (1)There were no significant difference in operating time,blood loss and hospital stay between PETD and PEID group (P>0.05),while UBE group was higher than those of PETD and PEID group (P<0.05). There was no statistical significance in fluoroscopy times between PEID and UBE group (P>0.05),but PETD group was higher than that of PEID and UBE group (P<0.05). (2)VAS of low back pain at 3 months after operation in UBE group was higher than that in PETD and PEID group (P<0.05),but there was no significant difference between PETD and PEID group (P>0.05). At the latest follow-up,there was no significant difference in VAS of low back pain among three groups (P>0.05). (3)Lower extremity pain of VAS and ODI among 3 groups after operation were significantly improved at all time points compared with those before opertaion(P<0.05),and there were no statistical significance between groups (P>0.05),and there were no statistical significance in interaction between different time points and operation groups (P>0.05). (4) At the latest follow-up,according to the modified MacNab standard,the results of PETD group were excellent in 27 patients,good in 16 patients,moderate in 4 patients,poor in 1 patient;in PEID group,27 patients got excellent result,12 good,3 moderate,and 1 poor;in UBE group,16 patients got excellent,10 good,2 moderate,and 2 poor. There was no significant difference among three groups (χ2=0.308,P>0.05). Recurrence of lumbar disc herniation occurred in 1 patient among each three groups,symptoms were improved in 2 patients after symptomatic treatment,and 1 patient was treated in other hospitals. PETD,PEID and UBE techniques could achieve good early clinical effects in treating lumbar disc herniation with similar complication rates. Both of PETD and PEID are single-channel minimally invasive surgery,with mild intraoperative tissue damage and quick postoperative recovery; while intraoperative fluoroscopy of PETD was relatively more frequent, and PEID was more suitable for L5S1 segment;UBE is a two-channel surgery,in which the intraoperative soft tissue damage is more severe,but exposure is broad,which is more suitable for complex cases.

Comparing Quality of Life: Discectomy Surgery versus Epidural Corticosteroid Injection for Lumbar Disc Herniation

BackgroundSelecting an efficient treatment for patients with radiculopathy caused by lumbar disc herniation (LDH) unresponsive to conservative management remains a challenging task under investigation, yielding varying results. This study aims to compare the outcomes of the two most prevalent invasive treatments. MethodsIn this retrospective longitudinal study, we enrolled patients with confirmed refractory symptomatic LDH who sought treatment at Valiasr Hospital and underwent either discectomy surgery or epidural steroid injection (ESI) between 2019 and 2022. The outcome measures included pain intensity using the Visual Analog Scale (VAS) and quality of life (QoL) using the SF-36 questionnaire. ResultsA total of 202 individuals (112 in the discectomy group and 90 in the ESI group) consisting of 90 males and 112 females, with a mean age of 50.9 ± 13.5 years, underwent analysis. In the univariate analysis, QoL scores were significantly higher in the discectomy group (57.4 ± 2.4) compared to the ESI group (44.2 ± 2.4) (p <0.01). Furthermore, the surgery group exhibited a significantly greater reduction in the Leg VAS score after treatment compared to the ESI group (mean difference: -2.59, 95% confidence interval (CI): -3.45 to -1.70, p <0.01). After adjusting for the most important confounding variables using multiple linear regression analysis, the association between surgery and higher QoL scores remained statistically significant (Unstandardized Coefficients B= 7.65, 95% CI: 0.55, 14.76, p = 0.03). ConclusionsOur findings indicate that discectomy surgery has a more pronounced effect on patient outcomes and is a preferable treatment option for LDH patients.

Current Approaches, Significance and Prognostic Impact of Lumbar Ligament Flavum Preserving Surgeries

Objectives: The aim of this study is to evaluate the use of flavum-preserving surgeries in lumbar disc herniation surgery, compare their clinical outcomes with standard microdiscectomy techniques, and demonstrate the transflaval microdiscectomy technique.&#x0D; Material and Methods: Between 2020 and 2023, a total of 48 patients who underwent transflaval microdiscectomy and 48 patients who underwent standard microdiscectomy at a single center were included in the study. Epidemiologic characteristics of the groups were described, and preoperative and postoperative visual analoge scale scores for leg pain (LPVAS) and back pain (BPVAS) were retrospectively analyzed.&#x0D; Results: There is no significant difference between the groups in preoperative mean LPVAS scores (p=0,474) and there is no significant difference between the groups in postoperative mean LPVAS scores (p=0,598). There is no significant difference between the groups in preoperative mean BPVAS scores (p=0,608). However there is a significant difference between the groups in postoperative mean BPVAS scores (p

Evaluation of Hemodynamic Changes and Fluid Response during Anesthesia in Lumbar Disc Hernias with Pleth Variability Index (PVI).

The study aimed to assess the pleth variability index (PVI) in patients undergoing lumbar disc herniation surgery under general and spinal anesthesia, exploring its correlation with fluid responsiveness, position, and hemodynamic parameters. Methods: This prospective study included 88 ASA 1-2 patients, aged 18-65, undergoing 1-3 h elective lumbar disc herniation surgery. Patients in groups GA and SA were observed for demographic, operative, and hemodynamic parameters at specified time points. (3) Results: PVI values were comparable between the GA and SA groups. After 250 mL of fluid loading, both groups showed a significant decrease in basal PVI at T2. Prone positions in GA exhibited higher PI values than in SA. The transition from a prone to supine position maintained PVI, while pulse and MAP decreased.; (4) Conclusions: PVI values were comparable in elective lumbar disc herniation surgery with general and spinal anesthesia. Both groups exhibited significant a PVI decrease at T2 after 250 mL of fluid loading, indicating fluid responsiveness. In general anesthesia, the prone position showed a lower MAP and higher PI values compared to spinal anesthesia. PVI and PI, sensitive to general anesthesia changes, could have beneficial additions to standard hemodynamic monitoring in spinal anesthesia management.

Surgically Treated Degenerative Lumbar Spine Diseases in Twins.

There is growing evidence to suggest a potential genetic component underlying the development and progression of lumbar spine diseases. However, the heritability and the concordance rates for the phenotypes requiring surgery for the common spine diseases lumbar spinal stenosis (LSS) and lumbar disc herniation (LDH) are unknown. The aim of this study was to determine the heritability and the concordance rates for LSS and LDH requiring surgery by studying monozygotic (MZ) and dizygotic (DZ) twin pairs. Patients between 18 and 85 years of age who underwent surgery for LSS or LDH between 1996 and 2022 were identified in the national Swedish spine registry (LSS: 45,110 patients; LDH: 39,272 patients), and matched with the Swedish Twin Registry to identify MZ and DZ twins. Pairwise and probandwise concordance rates, heritability estimates, and MZ/DZ concordance ratios were calculated. We identified 414 twin pairs (92 MZ and 322 DZ pairs) of whom 1 or both twins underwent surgery for LSS. The corresponding number for LDH was 387 twin pairs (118 MZ and 269 DZ pairs). The probandwise concordance rate for LSS requiring surgery was 0.25 (26 of 105) (95% confidence interval [CI], 0.14 to 0.34) for MZ twins and 0.04 (12 of 328) (95% CI, 0.01 to 0.07) for DZ twins. The corresponding values for LDH requiring surgery were 0.03 (4 of 120) (95% CI, 0 to 0.08) and 0.01 (4 of 271) (95% CI, 0 to 0.04), respectively. The probandwise MZ/DZ concordance ratio was 6.8 (95% CI, 2.9 to 21.5) for LSS and 2.3 (95% CI, 0 to 8.9) for LDH. The heritability was significantly higher in LSS compared with LDH (0.64 [95% CI, 0.50 to 0.74] versus 0.19 [95% CI, 0.08 to 0.35]). Our findings suggest that genetic factors may play an important role in the risk of developing LSS requiring surgery, whereas heredity seems to be of less importance in LDH requiring surgery.

Machine Learning Models for Predicting Disability and Pain Following Lumbar Disc Herniation Surgery

Lumber disc herniation surgery can reduce pain and disability. However, a sizable minority of individuals experience minimal benefit, necessitating the development of accurate prediction models. To develop and validate prediction models for disability and pain 12 months after lumbar disc herniation surgery. A prospective, multicenter, registry-based prognostic study was conducted on a cohort of individuals undergoing lumbar disc herniation surgery from January 1, 2007, to May 31, 2021. Patients in the Norwegian Registry for Spine Surgery from all public and private hospitals in Norway performing spine surgery were included. Data analysis was performed from January to June 2023. Microdiscectomy or open discectomy. Treatment success at 12 months, defined as improvement in Oswestry Disability Index (ODI) of 22 points or more; Numeric Rating Scale (NRS) back pain improvement of 2 or more points, and NRS leg pain improvement of 4 or more points. Machine learning models were trained for model development and internal-external cross-validation applied over geographic regions to validate the models. Model performance was assessed through discrimination (C statistic) and calibration (slope and intercept). Analysis included 22 707 surgical cases (21 161 patients) (ODI model) (mean [SD] age, 47.0 [14.0] years; 12 952 [57.0%] males). Treatment nonsuccess was experienced by 33% (ODI), 27% (NRS back pain), and 31% (NRS leg pain) of the patients. In internal-external cross-validation, the selected machine learning models showed consistent discrimination and calibration across all 5 regions. The C statistic ranged from 0.81 to 0.84 (pooled random-effects meta-analysis estimate, 0.82; 95% CI, 0.81-0.84) for the ODI model. Calibration slopes (point estimates, 0.94-1.03; pooled estimate, 0.99; 95% CI, 0.93-1.06) and calibration intercepts (point estimates, -0.05 to 0.11; pooled estimate, 0.01; 95% CI, -0.07 to 0.10) were also consistent across regions. For NRS back pain, the C statistic ranged from 0.75 to 0.80 (pooled estimate, 0.77; 95% CI, 0.75-0.79); for NRS leg pain, the C statistic ranged from 0.74 to 0.77 (pooled estimate, 0.75; 95% CI, 0.74-0.76). Only minor heterogeneity was found in calibration slopes and intercepts. The findings of this study suggest that the models developed can inform patients and clinicians about individual prognosis and aid in surgical decision-making.

Prolapsed Lumbar Intervertebral Disc (PLID) Surgery and Our Experiences

Background: Herniated lumbar disc is the most common specific cause of low back pain. Surgery results in better outcome for cases with exclusive severe radicular pain and health-related quality of life improves after lumbar disc herniation (LDH) surgery. Objective: To determine the outcome of lumbar disc herniation surgery and to assess the effect of factors that could predict the outcome of surgery. Materials and method: This observational study was done in Delta Medical College &amp; Hospital, Mirpur, Dhaka, during March 2016 to January 2019. We evaluated 54 patients who had undergone operations for lumbar disc herniation using three different surgical techniques (laminectomy, fenestration and discectomy, and spinous process osteotomy) for low back pain and radicular pain. Results: Forty six (85.19%) patients were male and 8(14.81%) were female. Age range was 18-60 years. Forty nine (90.74%) were new patient and 5(9.26%) had recurrent disc prolapse. Diagnosis was confirmed by MRI. Fifty (92.59%) patients had no pain after surgery and only 2(3.70%) patients needed reoperation and 2(3.70%) had occasional pain. Conclusion: Surgery for lumbar disc herniation is effective in reducing radicular pain. All three surgical approaches resulted in significant decrease in preoperative radicular pain and low back pain, but 100% good outcome was not achieved. Delta Med Col J. Jan 2021;9(1): 28-32

Inferior long-term outcomes after surgery for lumbar disc herniation in patients with prior lumbar spine surgery

BackgroundPrevious lumbar spine surgery is a frequent exclusion criterion for studies evaluating lumbar surgery outcomes. In real-life clinical settings, this patient population is important, as a notable proportion of patients evaluated for lumbar spine surgery have undergone prior lumbar surgery already previously. Knowledge about the long-term outcomes after microdiscectomy on patients with previous lumbar surgery and how they compare to those of first-time surgery is lacking.MethodsThe original patient cohort for screening included 615 consecutive patients who underwent surgery for lumbar disc herniation, with a median follow-up time of 18.1 years. Of these patients, 89 (19%) had undergone lumbar spine surgery prior to the index surgery. Propensity score matching (based on age, sex, and follow-up time) was utilized to match two patients without prior surgery with each patient with a previous surgery. The primary outcome measure was the need for further lumbar spine surgery during the follow-up period, and the secondary outcome measures consisted of present-time patient-reported outcome measures (Oswestry Disability Index, EuroQol-5D) and present-time ability to carry out employment.ResultsPatients who received previous lumbar surgeries had a higher need for further surgery (44% vs. 28%, p = 0.009) and had a shorter time to further surgery than the propensity score-matched cohort (mean Kaplan–Meier estimate, 15.7 years vs. 19.8 years, p = 0.008). Patients with prior surgery reported inferior Oswestry Disability Index scores (13.7 vs. 8.0, p = 0.036). and EQ-5D scores (0.77 vs. 0.86, p = 0.01). In addition, they had a higher frequency of receiving lumbar spine-related disability pensions than the other patients (12% vs. 1.9%, p = 0.01).ConclusionsPatients with previous lumbar surgery had inferior long-term outcomes compared to patients without prior surgery. However, the vast majority of these patients improved quickly after the index surgery. Furthermore, the difference in the patients’ reported outcomes was small at the long-term follow-up, and they reported high satisfaction with the results of the study surgery. Hence, surgery for these patients should be considered if surgical indications are met, but special care needs must be accounted for when deliberating upon their indications for surgery.

Return to flight duty (RTFD) after posterior lumbar spine surgery for symptomatic lumbar disc herniation (LDH) and lumbar isthmic spondylolisthesis (LIS) in Chinese military pilots

BackgroundSymptomatic lumbar disc herniation (LDH) and lumbar isthmic spondylolisthesis (LIS) present significant challenges for military pilots, which may result in grounding if not effectively managed. Surgical treatment for LDH and LIS may offer a pathway to return to flight duty (RTFD), but recent data on this crucial topic is lacking. This study seeks to address this gap by investigating the RTFD outcomes among Chinese military pilots who have undergone lumbar spine surgery for symptomatic LDH and LIS.MethodsA retrospective review was conducted on active-duty military pilots who underwent isolated decompressive or fusion procedures at an authorized military medical center from March 1, 2007, to March 1, 2023. The analysis utilized descriptive statistics to examine demographic, occupational, surgical, and outcome data, with a particular focus on preoperative flight status, recommended clearance by spine surgeons, and actual RTFD outcomes and time.ResultsAmong the identified cases of active-duty military pilots with LDH or LIS treated by lumbar surgery (n = 24), 70.8% (17 of 24) consistently maintained RTFD status without encountering surgical complications or medical issues during the follow-up period. Of the seven pilots who did not RTFD, one retired within a year of surgery, two had anterior cruciate ligament injuries, three had residual radicular symptoms, and one had chronic low back pain. Excluding pilots who retired and did not RTFD for reasons unrelated to their lumbar conditions, the RTFD rate stood at 81.0% (17 of 21). The median time for recommended clearance by spine surgeons was 143.0 days (inter-quartile range, 116.5–196.0), while the median duration for actual RTFD attainment was 221.0 days (inter-quartile range, 182.0–300.0). The median follow-up post-lumbar surgery was 1.7 years (inter-quartile range, 0.4–2.9).ConclusionMost military pilots diagnosed with symptomatic LDH and LIS can continue their careers and regain active-duty flight status following lumbar spine surgery, as reflected by the high RTFD rate. Lumbar spine surgery can successfully alleviate the physical constraints associated with spinal conditions, facilitating the return of military pilots to their demanding profession.

Screening patients requiring secondary lumbar surgery for degenerative lumbar spine diseases: a nationwide sample cohort study

This study aims to identify healthcare costs indicators predicting secondary surgery for degenerative lumbar spine disease (DLSD), which significantly impacts healthcare budgets. Analyzing data from the National Health Insurance Service-National Sample Cohort (NHIS-NSC) database of Republic of Korea (ROK), the study included 3881 patients who had surgery for lumbar disc herniation (LDH), lumbar spinal stenosis without spondylolisthesis (LSS without SPL), lumbar spinal stenosis with spondylolisthesis (LSS with SPL), and spondylolysis (SP) from 2006 to 2008. Patients were categorized into two groups: those undergoing secondary surgery (S-group) and those not (NS-group). Surgical and interim costs were compared, with S-group having higher secondary surgery costs ($1829.59 vs $1618.40 in NS-group, P = 0.002) and higher interim costs ($30.03; 1.86% of initial surgery costs vs $16.09; 0.99% of initial surgery costs in NS-group, P < 0.0001). The same trend was observed in LDH, LSS without SPL, and LSS with SPL (P < 0.0001). Monitoring interim costs trends post-initial surgery can effectively identify patients requiring secondary surgery.

The Impact of the Placement of the L5 Vertebra in Relation to the Intercrest Line on the Level of Disc Herniation.

To determine whether there is a correlation between a deeply seated L5 vertebra in relation to the intercrest line (ICL) and the level of degeneration of lumbar discs. The study included 152 patients who underwent surgery for lumbar disc herniation. After analyzing the radiographs, the patients were separated into two groups. Group 1 patients had an ICL that passed through the L4 corpus, and Group 2 patients had an ICL that passed through the L4-5 disc distance or the L5 vertebra. Group 1 patients were classified as having a deeply seated L5 vertebra, while Group 2 patients were classified as not having a deeply seated L5 vertebra. The study found that male patients had a significantly higher incidence of a deeply seated L5 vertebra compared to female patients (p=0.003). Patients who underwent surgery at the L4?5 level exhibited disc heights that were notably higher than those who underwent surgery at the L5-S1 level. In Group 1, 68% of the patients had surgery at the L4-5 level, compared to only 41.7% in Group 2 (p=0.009). When investigating the effects of the position of the L5 vertebra in relation to the ICL at the L4-5 and L5-S1 disc levels, the study found that having a deeply seated L5 vertebra protected against L5-S1 disc herniation and that L4-5 disc herniation was more common in these patients. This is believed to be due to the L5?S1 segment being less mobile when the L5 vertebra is deeply seated.

The Impact of Preoperative Adaptive Training on Postoperative Outcomes in Lumbar Spine Fusion Surgery for Lumbar Disc Herniation: A Retrospective Analysis.

Lumbar disc herniation, often treated with surgical decompression when conservative measures fail, presents challenges due to prolonged prone positioning in surgeries. This retrospective study evaluates the benefits of preoperative adaptive training to mitigate post-surgical physiological changes. A review of medical records from June 2021 to March 2023 identified 170 patients unresponsive to conservative treatments. Grouped into adaptive training and control groups based on historical data, the former had undergone exercises to prepare for surgery and postoperative changes. Vital signs and VAS scores were extracted from patient records to assess training impact. The adaptive training group demonstrated stabilized vital signs intraoperatively, with a notable improvement in surgical exposure compared to the control group. However, there were no significant differences in operative time or blood loss between the groups. Additionally, postoperative VAS scores showed no significant improvement in the adaptive training group at follow-up intervals of 14 days, 1 month, and 3 months post-operation, compared to the control group. Our study reveals that preoperative adaptive training stabilizes intraoperative blood pressure fluctuations in lumbar disc herniation surgeries. However, this stabilization does not significantly impact long-term postoperative pain management. This highlights the need for further research to explore comprehensive strategies that effectively combine preoperative training with postoperative care.

Low-Back Outcome Scale and the Oswestry Disability Index they Reflective of Patient Satisfaction

Background: Low back pain is the most common type of pain. The causes of many painful conditions of the low back remain obscure. Low back pain bothers not only patients but also the experts about its multidisciplinary approaches. The typical background of a low back incidence is a faulty postural pattern. A mechanical or functional strain causing muscular misbalance in one part of the body may soon result in compensatory changes in other parts. The Low-Back Outcome Scale (LBOS) of Greenough and Fraser and the Oswestry disability index (ODI) were compared to the patient satisfaction index (PSI) in lumbar disc herniation (LDH) surgery. Methods: This prospective interventional study was conducted in department of Orthopaedic Surgery, BSMMU, Dhaka from October 2017 to September 2019. A total of 22 patients who underwent discectomy were followed through assessment of pre and post-surgical satisfaction by the PSI, the LBOS, and the ODI. The LBOS were rated as satisfied if the outcomes were excellent or good and as dissatisfied if fair and poor. Considering the ODI, clinically satisfied was defined as a 13-point improvement from the baseline ODI scores. Phi (Φ) correlation analysis was used to study the correlation among the PSI, the LBOS and the ODI scores as proxy for patients’ satisfaction. Results: In this study, out of 22 patients 8 (36.4%) were 35-45 years of age, 8 (36.4%) were 46- 55years, 4 (18.2%) were 56- 65 years and 2 (9.1%) were 66-70 years old. The mean (± SD) age of the patients was 51.1±9.7 years and the youngest and the oldest patients were 35 and 70 years respectively. Among 22 subjects, majority of the study subjects 15 (68.2%) were male and only 7 (31.8%) were female. Significant improvement from the pre- to post-operative ODI scores was observed. Post-surgical satisfaction based on the PSI, the ODI, and the LBOS were 72.7%, 68.1%, and 81.1%, respectively. Regarding patient satisfaction, there were weak associations between LBOS vs. PSI and ODI vs. PSI (Φ=−0.054, P=0.533) and (Φ=−0.129, P=0.136), respectively. Conclusions: Our study showed that the ODI and the LBOS were not reflective of patients’ satisfaction after discectomy.
