Comparative Outcome Data Using Different Techniques for Posterior Lumbar Fusion: A Large Single-Center Study.

STUDY DESIGN: Retrospective single-center study. PURPOSE: This study aims to evaluate perioperative and intermediate-term clinical outcomes of patients undergoing different lumbar fusion techniques. OVERVIEW OF LITERATURE: Various open and minimally invasive techniques for lumbar fusion are available, but previous studies comparing lumbar fusion techniques have heterogeneous data, making interpretation challenging. METHODS: Between 2011 and 2018, data from 447 consecutive patients undergoing one/two-level lumbar fusion were analyzed. Posterior lumbar interbody fusion (PLIF) with bilateral muscle strip or Wiltse approach, open transforaminal lumbar interbody fusion (TLIF) and minimally invasive TLIF, and posterolateral fusion only were among the surgical techniques used. Core outcomes measure index (COMI) questionnaires were distributed before surgery and at 3 months, 1 year, and 2 years postoperatively to establish patient selfreported outcome measures. Demographic data (age, gender, and body mass index [BMI]) for each patient were also collected in addition to surgical indication, previous operative history, perioperative outcomes, and complications, and whether later revision surgery was required. Pearson's chi-square test, Kruskal-Wallis test, repeated measure mixed-effects models, and ordinal logistic regression were used for statistical analysis. RESULTS: Postoperative COMI scores improved across all procedures compared with pre-surgery (p<0.001). There was no significant difference between different postoperative COMI scores. Significant predictors of higher postoperative COMI score included higher pretreatment COMI score (p≤0.001), previous surgery (p≤0.04), younger age (p≤0.05), higher BMI (p≤0.005), and the indications of lytic spondylolisthesis (p=0.02) and degenerative disc disease (p<0.001). Patients undergoing minimally invasive TLIF had a significantly shorter post-surgery stay than patients undergoing open PLIF (Kruskal-Wallis test, p=0.03). CONCLUSIONS: At 2 years postoperatively, there was no significant difference in clinical outcomes between open and minimally invasive techniques. These findings suggest that the main determinant of surgical approach should be surgeon preference and training.

Giant adrenal gland pseudo-cyst: a case report with literature review.

Adrenal Gland Cysts are rare among all the pathologic cysts that occur in human beings; the pseudo-cyst variety even rarer. Adrenal pseudo-cysts are asymptomatic, non-functional, small, and incidentally discovered disease entities. Their clinical presentation is usually the result of their mass effects. Thanks to the advanced diagnostic technology, more such cases are being discovered timely and managed surgically, before life-threatening complications occur. Open surgical treatment remains the treatment of choice for giant cysts.

Evaluation of the thermographic response of the lumbar region in dogs with bilateral hip osteoarthritis.

Infrared thermography is suggested as a method of medical assistance for evaluating anatomical regions where there may be some inflammatory or painful condition that requires immediate medical attention. For this reason, this study aimed to characterize digital thermography of the lumbar region in police working dogs with hip osteoarthritis, 47 dogs with bilateral hip osteoarthritis were evaluated. A thermographic dorsoventral view of the dogs' backs were obtained, and mean and maximum temperatures were determined. In addition, results from the Canine Brief Pain Inventory, Liverpool Osteoarthritis in Dogs (LOAD), the Canine Orthopedic Index, and weight-bearing distribution evaluation were collected. Results were compared with an Independent Samples T-Test or ANOVA, followed by an LSD post hoc. Multiple regression was run to predict temperatures from age, sex, breed, body weight, and Orthopedic Foundation for Animals hip score and to predict clinical metrology scores and weight-bearing distribution results from temperature results. The sample included 28 males and 19 females, with a mean age of 6.3 ± 2.5 years and bodyweight of 26.9 ± 5.1 kg, with osteoarthritis hip scores of mild (70.2%), moderate (21.3%), and severe (8.5%). Significant differences were observed in mean temperatures between German Shepherd Dogs (GSD) and Labrador Retrievers (LR) (p < 0.01), and LR and Belgian Malinois (BM) (p=0.02). Mean temperature contributed to the prediction of LOAD and stiffness. LR showed significantly higher temperature values than GSD and BM. No differences were observed between osteoarthritis hip scores and mean temperature values contributed to LOAD scores' prediction. This relation needs to be addressed in further studies, involving a larger number of animals, and to determine changes in response to treatment.

TLIF Online Videos for Patient Education-Evaluation of Comprehensiveness, Quality, and Reliability.

Over the last few decades, the number of lumbar interbody fusion surgeries performed has been constantly increasing, with transforaminal lumbar interbody fusion (TLIF) being one of the most common surgical techniques. Due to easy accessibility, patients frequently use YouTube to obtain information on health-related issues. Consequently, online video platforms may be a valuable tool for patient education. The aim of this study was to assess the quality, reliability, and comprehensiveness of online videos on TLIF. We screened 180 videos on YouTube, yielding a total of 30 videos that met the inclusion criteria. These videos were evaluated using Global Quality Scale, DISCERN reliability tool, and JAMA Benchmark Score, and assessed in regard to their comprehensiveness and coverage of relevant aspects. At the time of rating, the videos had between 9188 and 1,530,408 views and between 0 and 3344 likes. The median rater assessment for all videos was "moderate quality". GQS and subjective grades showed a moderate to strong statistically significant association with views and likes. Considering this association of GQS and subjective grade with views and likes, these criteria could be used by laypersons to identify good-quality content. Nevertheless, there is an urgent need for peer-reviewed content that covers all of the relevant aspects.

Dermatofibrosarcoma Protuberans Over Right Lumbar Region: A Case Report.

Dermatofibrosarcoma protuberans is a rare, low-grade dermal soft-tissue tumor with a high propensity for recurrence but a low propensity for metastatic spread. It mostly affects the head, neck, proximal extremities, and trunk. We report a case of dermatofibrosarcoma protuberans over the right lumbar region. The patient presented with swelling in the right lumbar region measuring 3 cm × 3 cm. The local region ultrasonography (USG) revealed a well-defined hypoechoic lesion in the subcutaneous area. The patient was provisionally diagnosed with a peripheral nerve sheath tumor under evaluation. USG-guided fine needle aspiration cytology (FNAC) suggested a spindle cell tumor. Wide local excision of the tumor was performed. Monomorphic spindle cells in a storiform pattern were observed by histological evaluation. The neighboring adipose tissue was invaded by the tumor cells in a honeycomb-shaped pattern. The histological features were suggestive of Dermatofibrosarcoma Protuberans. Due to the high likelihood of recurrence, it is crucial to monitor these patients for an extended period of time.

Post-Mortem Computed Tomographic Features of the Most Caudal Lumbar Vertebrae, Anatomical Variations and Acquired Osseous Pathological Changes, in a Mixed Population of Horses.

The radiographic, ultrasonographic, and scintigraphic findings of horses with thoracolumbosacral pain have been previously reported. In this study, the computed tomographic appearance of anatomical variations and pathological changes of the equine caudal lumbar region through a post-mortem examination were investigated. A total of 40 horses that had died or were submitted for euthanasia, for reasons unrelated to the study, were included in the study. From all the specimens, the modified vertebral system was adopted to evaluate and describe the four most caudal lumbar vertebrae, which were numbered from a caudal reference point (lumbosacral junction), with the segment number designated within parentheses (i.e., L(i)-L(iv)). Contact of the spinous processes was detected in 21 specimens (54%) and fusion in 6 specimens (15%). Lumbar spondylosis was seen in 17 specimens (42.5%), more commonly on the lateral aspect or on both ventral and lateral aspects in 12 specimens (71%). The presence of spondylosis was found more commonly in older horses (p < 0.001). There was no difference in bony density in specimens with spondylosis or spinous processes contact compared to specimens without. The highest prevalence of bony changes was found at L(ii)-L(i) intertransverse joints in 28 specimens (97%) on the left and in 22 specimens (96%) on the right side. Spondylolisthesis and partial fusion of the L(ii)-L(i) vertebral disc were found in association with degenerative pathologies. This study showed a high frequency of several anatomical variations and acquired osseous pathological changes in the most caudal lumbar vertebrae via a CT examination.

Wound drain in lumbar arthrodesis for degenerative disease: an experimental, multicenter, randomized controlled trial.

INTRODUCTION: Drains for surgical wound management are frequently used in spine surgery. They are often used to decrease the incidence of postoperative hematoma and decrease wound tension. No conclusive evidence in the literature supports using drains to avoid complications in degenerative lumbar spine surgery. PURPOSE: We aimed to evaluate wound drains in patients with lumbar arthrodesis for degenerative disorders based on clinical outcomes, complications, hematocrit, and length of stay. STUDY DESIGN: A multicenter randomized prospective controlled clinical trial. PATIENT SAMPLE: We enrolled surgical candidates for posterior lumbar decompression and fusion surgery for degenerative disorders from October 2019 to August 2021. Patients were randomized into the drain or nondrain group at nine hospitals. The inclusion criteria were as follows: patients aged 40 to 80 years with lumbar and radicular pain, lumbar degenerative disorder, and primary surgery up to three levels. The exclusion criteria were bleeding abnormalities, bleeding >2,500 mL and dural tears. OUTCOME MEASURES: Preoperative data including Oswestry disability index (ODI), SF-36, lumbar and lower extremity visual analog scale (VAS), body mass index (BMI), hematocrit, and temperature were recorded. Surgical parameters, including surgical time, complications, estimated blood loss (EBL), postoperative temperature and hematocrit (days 1 and 4), dressing saturation, and length of hospital stay (LOS), were registered. METHODS: The two groups were assessed preoperatively, perioperatively and at the 1-month follow-up. A REDCap database was used for registration. Data analysis was performed using classical statistics. RESULTS: One hundred one patients were enrolled using the Redcap database, and 93 patients were evaluated at the final follow-up. Forty-five patients were randomized to the drain group, and 48 were randomized to the nondrain group. The preoperative characteristics were equivalent in both groups: demographic aspects, pain, ODI, SF-36, BMI, hematocrit, and spine pathology. Surgical time, EBL and complications were similar, with no difference between the groups. No difference was found between BMI and complications. No difference was observed in dressing saturation or postoperative temperature between the groups. The postoperative day 4 hematocrit was higher in the nondrain group [36.4% (32-39)] than in the drain group [34% (29.7-37.6)] without statistically differences (p=.054). The LOS was higher in the drain group [4 (3-5) days] than in the nondrain group [3 (2-4) days] (p=.007). The quality-of-life score, SF-36, was higher in the nondrain group [67.9 (53.6-79.2)] than in the drain group [56.7 (49.1-66)] (p=.043). CONCLUSIONS: Nondrain patients presented shorter LOS and better outcomes, with similar complication rates. No difference was found between BMI and complications. Based on this study, in patients undergoing primary posterior spinal decompression and fusion up to three levels for degenerative lumbar disorders, we do not recommend the use of postoperative drains.

The Brazilian Portuguese version of the Pregnancy Mobility Index: Cross-cultural adaptation and psychometric evaluation - a validation study

ABSTRACT BACKGROUND: The Pregnancy Mobility Index (PMI) was developed to assess mobility in pregnant women in the Netherlands. At present, no similar questionnaire is available in Brazil. OBJECTIVE: The present study aimed to translate, cross-culturally adapt, and evaluate the psychometric properties of a Brazilian PMI. DESIGN AND SETTING: The present study was a validation study conducted at the Universidade Federal do Paraná and a public maternity ward in Curitiba, Brazil. METHODS: Text translation and cross-cultural adaptation followed international guidelines. Construct validity, internal consistency, and inter- and intra-rater reliability tests included 97 women. The Pelvic Girdle Questionnaire, Multidimensional Pain Evaluation Scale, Schober's test, and lumbar spine range of motion assessment were administered on the first day. Intra-rater reliability (n = 19) was measured after 15 days. Exploratory factor analysis was performed, and the correlation matrix was analyzed using Pearson's coefficient. RESULTS: Pregnant women (88%) understood the cultural adaptation process. The internal consistency was high (Cronbach's alpha > 0.90), construct validity was moderate, with significant correlation between lumbar spine range of motion (r = 0.283-0.369) and Schober's test (r = -0.314), and high correlation between the Multidimensional Pain Evaluation Scale (r = -0.650 and -0.499) and Pelvic Girdle Questionnaire (r = -0.737). Intra- and inter-rater reliabilities were excellent (intraclass correlation coefficient = 0.932 and 0.990, respectively). CONCLUSION: The Brazilian version of the PMI was successfully translated with excellent reliability and moderate-to-high construct validity. It is an important tool for assessing mobility in pregnant women. CLINICAL TRIAL: RBR-789tps (Validation study), https://ensaiosclinicos.gov.br/rg/RBR-789tps.

Effects of External Focus and Motor Control Training in Comparison with Motor Control Training Alone on Pain, Thickness of Trunk Muscles and Function of Patients with Recurrent Low Back Pain: A Single Blinded, Randomized Controlled Trial.

Background: Recurrent low back pain (RLBP) affects different structures in the lumbar spine. Exercise therapy is highly recommended as one of the first-line treatments. One crucial variable introduced to enhance RLBP is the external focus. The present study aimed to investigate the effects of external focus training on pain, the thickness of transverse abdominis (TrA), internal oblique (IO), external oblique (EO), and lumbar multifidus (LM) muscles, kinesiophobia, fear-avoidance beliefs, and disability of people with RLBP. Methods: This randomized-controlled trial consisted of 38 RLBP patients. Patients were randomly divided into two groups the treatment group (n=19) that received external focus training in addition to motor control training and the control group (n=19) that received motor control training alone. The primary outcome was pain intensity, and secondary outcomes were the thickness of TrA, IO, EO, LM muscles, kinesiophobia, fear-avoidance beliefs, and disability that were measured at the baseline and after 16 sessions of interventions. The interventions were performed three sessions weekly. Results: Reduction in pain intensity was more significant in the intervention group than in the control group (P<0.001, Cohen's d=-1.47). The thickness of TrA muscle in the contraction condition of the intervention group was significantly more on the left side (P<0.001, Cohen's d=1.05) than on the right side (P=0.03, Cohen's d=0.44). Other outcomes showed no significant differences. However, the Cohen's d effect size for the left IO (Cohen's d=0.57) and TKS (Cohen's d=-0.53) were moderate. Conclusion: In RLBP patients, external focus and motor control training could effectively reduce the pain. Although this intervention could increase the thickness of the TrA muscle of RLBP, it has no significant effect on the thickness of IO, EO, and LM muscles. In addition, the obtained results indicated that this intervention has no significant effect on kinesiophobia, fear-avoidance beliefs, and disability..

Objective: Determine the risk factors of lumbar pathologies in patients employed and affi-liated with the health system, based on physical examination, habits, personal history, and occupational risk factors.Materials and Methods: The study design is retrospective, cross-sectional. In a sample of 668 adult workers from Ecuador. The binary logit response predictive model was applied to identify risk factors and supervised learning methodology (classification trees) was used to classify patients according to the degree of lumbar pathology.Results: The logistic predictive model has a sensitivity of 62.5%, a specificity of 63.7%, the area under the ROC curve was 0.63, and precision of 63.4% was determined.Conclusion: The factors that increase the risk of the most frequent lumbar pathology (low back pain) in order of importance in patients are: younger age, female sex, tend to be expo-sed to psychosocial risk factors at work, and lower risk of having mechanical factors.

Reliability and validity of Turkish versions of Sciatica Bothersomeness and Sciatica Frequency Index.

BACKGROUND: The Sciatica Frequency Index (SFI) and Sciatica Bothersomeness Index (SBI) are two separate indices scored for both the bothersomeness and frequency of radiating symptoms. There is no Turkish scale used specifically for sciatica. OBJECTIVE: We aimed to translate SBI and SBI in Turkish and investigate the reliability and validity of these indices. METHODS: A total of 80 patients with lumbar disc herniation (LDH) were prospectively included. Construct validity was assessed by comparing the SBI and SFI with subscales of Short Form 36 (SF-36), back and leg Numeric Rating Scale (NRS) and Roland Morris Disability Questionnaire (RMDQ). Reliability was assessed by internal consistency (Cronbach's alpha) and test-retest reliability. RESULTS: A weak correlation was found between SBI/SFI, back NRS and SF-36 subgroups while a moderate correlation was found between SBI/SFI, RMDQ and leg NRS. The SBI and SFI had high internal consistency measured by Cronbach's alpha (0.76 and 0.73). Test-retest reliability of the SBI and SFI were 0.95 (95% CI: 0.92-0.97) and 0.95 (95% CI: 0.92-0.97) respectively, indicating excellent reliability. CONCLUSION: The Turkish versions of the SFI/SBI are a valid and reliable tool supporting their usability in patients with LDH-induced sciatica.

Multifidus muscle cross-sectional area adaptations over two volleyball seasons and one off-season in athletes with and without low back pain.

BACKGROUND: The multifidus muscle is important in spine stabilization. Atrophy of the multifidus muscle has been associated with low back pain. OBJECTIVE: To examine multifidus muscle cross-sectional area (CSA) adaptations over two volleyball seasons and one off-season in volleyball athletes experiencing low back pain or no low back pain. METHODS: Twelve female NCAA division 1 volleyball athletes participated. Athletes were placed into a low back pain or no low back pain group. Athlete's multifidus was imaged and measured using ultrasound at four time points across seasons. Imaging time points were before season one, following season one, following off-season, and following season two. A single level mixed-model analysis of variance was used for all analyses. A Tukey HSD post hoc test was used to determine differences between and within the low back pain and the no low back pain groups. RESULTS: Following off-season training the pain group had clinically significant smaller multifidus CSA at the L4 (-2.36 cm2 difference or 17.5%) and L5 (-2.40 cm2 or 12.5%) levels. Non-significant (p> 0.05) decreases in multifidus CSA were seen in both groups following season one and two. Athletes with pain had decreased multifidus CSA at the L4 and L5 vertebral levels at all time points which was non-significant (p> 0.05). CONCLUSIONS: Clinically significant decreases in multifidus CSA occurred in female volleyball athletes with low back pain at the L4 and L5 level following off-season training. Volleyball athletes with pain had smaller multifidus CSA averages at all time points measured of the two year period.

[Spinal manipulation therapy in low back pain : Why? When? Where? How?] / Manualmedizinische Interventionen bei Kreuzschmerzen : Warum? Wann? Wo? Wie?

BACKGROUND: Manipulation and mobilisation for low back pain are presented in an evidence-based manner with regard to mechanisms of action, indications, efficacy, cost-effectiveness ratio, user criteria and adverse effects. Terms such as non-specific or specific are replaced by the introduction of "entities" related to possible different low back pain forms. EFFICACY: MM is effective for acute and chronic low back pain in terms of pain relief, recovery of function and relapse prevention. It is equally effective but less risky compared to other recommended therapies. MM can be used alone in acute cases and not only in the case of chronic low back pain where it is always and necessarily part of a multimodal therapy programme, especially in combination with activating measures. The users of MM should exclusively be physician specialists trained according to the criteria of the German Medical Association (Bundesärztekammer) with an additional competence in manual medicine or appropriately trained certified therapists. The application of MM follows all rules of Good Clinical Practice. ADVERSE EFFECTS: Significant adverse effects of MM for low back pain are reported in the international literature with a frequency of 1 per 50,000 to 1 per 3.7 million applications, i.e. MM for low back pain is practically risk-free and safe if performed according to the rules of the European Training Requirements of the UEMS.

Role of low-intensity pulsed ultrasound on lumbar spondylolysis: A systematic review.

OBJECTIVE: To systematically review the role of low-intensity pulsed ultrasound on lumbar spondylolysis. METHODS: Literature search was conducted on PubMed, Embase, CINAHL, Web of Science, PEDro and Scopus databases to identify relevant studies published between 2010 and 2020 by using medical subject headings and applying Booleans, such as low-intensity pulsed ultrasound OR interventional ultrasound AND lumbar spine OR lumbar region AND spondylolysis OR stress fracture. Unpublished studies were hand-searched in the journals, abstracts of conferences were reviewed, and citation index was used for searching experts in the field and then contacting them for information. Studies included were the ones that had at least one of the following outcomes: bone union rate, treatment period to bone union and time to return to previous activities. RESULTS: Of the 243 studies identified, 228(94%) were full text articles and only 2(0.8%) studies were critically appraised for qualitative synthesis based on bone union rate, treatment period to bone union, and time to return to previous activities. CONCLUSIONS: Low-intensity pulsed ultrasound was found to be effective for bone union and a useful therapy for quick return to playing sports in patients with lumbar spondylolysis.

The Role of Rehabilitative Ultrasound Imaging Technique in the Lumbopelvic Region as a Diagnosis and Treatment Tool in Physiotherapy: Systematic Review, Meta-Analysis and Meta-Regression.

Rehabilitative ultrasound imaging (RUSI) technique seems to be a valid and reliable tool for diagnosis and treatment in physiotherapy and has been widely studied in the lumbopelvic region the last three decades. The aims for this utility in clinical settings must be review through a systematic review, meta-analysis and meta-regression. A systematic review was designed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines with PROSPERO registration and per review in all phases of the process using COVIDENCE, analysis of risk of bias and meta-analysis using REVMAN, and meta-regression calculation using STATA. Database screening provided 6544 references, out of which 321 reported narrative synthesis, and 21 reported quantitative synthesis, while only 7 of them provided comparable data to meta-analyze the variables pain and muscle thickness. In most cases, the forest plots showed considerable I2 heterogeneity indexes for multifidus muscle thickness (I2 = 95%), low back pain (I2 = 92%) and abdominal pain (I2 = 95%), not important for transversus abdominis muscle thickness (I2 = 22%), significant heterogenity (I2 = 69%) depending on the subgroup and not important internal oblique muscle thickness (I2 = 0%) and external oblique muscle thickness (I2 = 0%). Meta-regression did not provide significant data for the correlations between the variables analyzed and the intervention, age, and BMI (Body Mass Index). This review reveals that RUSI could contribute to a high reliability of the measurements in the lumbopelvic region with validity and reliability for the assessments, as well as showing promising results for diagnosis and intervention assessment in physiotherapy compared to the traditional model, allowing for future lines of research in this area.

ERECTOR SPINAE PLANE BLOCK AND PLACEMENT OF PERINEURAL CATHETER FOR DEVELOPMENTAL HIP DISORDER SURGERY IN CHILDREN.

The ultrasound-guided erector spinae plane (ESP) block is a novel interfascial plane block technique providing analgesic effects in different localizations of the body, in accordance with the level of administration. Although ESP block is usually performed in the thoracic region in pediatric patients, it is possible to achieve ESP block in the lumbar region as well. Postoperative pain management is essential in patients undergoing operative hip treatment, one of the most common procedures in pediatric orthopedic surgery. We report on a case of effective intraoperative analgesia achieved by ultrasound-guided lumbar ESP block and another case of effective intra- and postoperative analgesia accomplished with perineural catheter placement in addition to lumbar ESP block, both performed in children surgically treated for developmental hip disorders.

The lumbar region localization using bone anatomy feature graphs.

The automatic localization of the lumbar region is essential for the diagnosis of lumbar diseases, the study of lumbar morphology, and the surgical planning. Although the existing researches have made great progress, it still faces several challenges. First, the various lumbar diseases and pathologies cause different abnormalities in the lumbar shape and appearance. Second, the numbers of lumbar vertebrae are irregular (some people have an additional vertebra L6). To tackle these challenges, we propose a novel lumbar region localization method based on bone anatomy feature graphs. Specifically, a feature graph (called LS) considering the anatomy of the sacrum and the lumbar vertebra is proposed to locate the inferior boundary of L5 or L6. A feature graph (called TL) considering the anatomy of the thoracic vertebra and the lumbar vertebra is proposed to locate the superior boundary of L1. Extensive experimental analysis is performed on a public available dataset xVertSeg and a private dataset which contains 197 CT scans. The localization results show that the proposed method is robust and can be applied to normal scans, scoliosis scans, deformity scans, hyperosteogeny scans, 6 lumbar vertebrae scans and lumbar implant scans. The Dice and Jaccard coefficients are 98.09 ± 0.84% and 96.27 ± 1.62% respectively. Graphical Abstract Lumbar Region Localization Framework.

[Ventral support in dorsal lumbar fusion surgery : A case report with many incidents]. / Die ventrale Abstützung bei dorsalen lumbalen Fusionsoperationen : Ein Fallbericht mit vielen Zwischenfällen.

Anterior column support in posterior lumbar fusion surgery is essential for the outcome of the operation, particularly in the case of unstable pathologies such as spondylolisthesis or spondylodiscitis. The complicated case of a patient with simultaneous spondylolisthesis and spondylodiscitis is presented and reevaluated based on the literature and our own treatment algorithm. In the case of spondylodiscitis alone, iliac crest interposal is sufficient as a support. In the case of additional disturbances of the sagittal profile, a cage implantation is preferred.
