[Comparative analysis of the results of microdiscectomy and minimally invasive transforaminal lumbar interbody fusion in the treatment of adjacent-level intervertebral disc herniations with lumbosacral transitional vertebra in elderly patients.]

The purpose of the study was a comparative analysis the effectiveness of microsurgical discectomy and minimally invasive transforaminal lumbar interbody fusion in the treatment of disk herniation adjacent to the anomaly of the lumbosacral junction segment in elderly patients. The study included 80 elderly patients (over 60 years old), divided into two groups: the 1st-(n=39) who underwent microsurgical discectomy; the 2nd- patients (n=41) operated on using minimally invasive transforaminal interbody fusion and percutaneous transpedicular stabilization (MI-TLIF). For the comparative analysis, we used gender characteristics (gender, age), constitutional characteristics (BMI), degree of physical status according to ASA, intraoperative parameters of interventions and the specificity of postoperative patient management, clinical data, and the presence of complications. Long-term outcomes were assessed at a minimum follow-up of 3 years. As a result, it was found that the use of MI-TLIF allows achieving better long-term clinical outcomes, fewer major complications in comparison with the microsurgical discectomy technique in the treatment of disc herniation adjacent to the anomaly of the lumbosacral junction segment in elderly patients.

The significance of cervical discopathy diagnosis in patients with mastalgia.

OBJECTIVE: The primary aim of this study was to explore the involvement of cervical discopathy in the development of non-cyclic mastalgia by employing cervical magnetic resonance imaging (MRI). PATIENTS AND METHODS: A total of 407 patients were included in the study. Individualized management plans were developed for each patient. Pathological findings in MRI results were assessed by specialists in physical therapy and neurosurgery, and appropriate treatment was administered. Visual assessments of patients were conducted. The Analog Scale (VAS) scoring system was used at the initial presentation, and patients were evaluated at 1 and 3 months following the treatment. RESULTS: In the MRI examinations of the patients included in the study, simultaneous cervical disc protrusion was observed in 29% (n: 124) of those with annular bulging. Comparing the VAS scores of patients before treatment, at the 1st and at the 3rd month showed a significant decrease in mastalgia pain (p < 0.001). CONCLUSIONS: The diagnosis of cervical discopathy holds significant importance in the treatment of mastalgia patients. Therefore, clinicians should keep the cervical spine in mind as a potential contributing factor to mastalgia.

C3-C4 cervical disc herniation producing Brown-Séquard syndrome: A case report and review of the literature.

Brown-Séquard Syndrome (BSS) is a rare form of incomplete spinal cord injury and is characterized by ipsilateral motor deficit and contralateral sensory loss. BSS is commonly associated with traumatic etiologies, but non-traumatic causes should be considered as well. A 38-year-old woman presented with a 3-week history of weakness in her right upper extremity, and she has developed numbness and tingling in her left upper and lower extremities over the past week and a half, along with some motor difficulty. Imaging showed a large right paracentral disc protrusion at the C3-C4 level causing severe spinal canal narrowing and resulting in abnormal cord signal. The patient subsequently underwent a C3-4 cervical total disk replacement. Hemovac placed during surgery was removed on post-op day one, and she was re-evaluated by PT/OT and recommended for outpatient therapies on post-op day two. Our case, along with a review of the literature, highlights those non-traumatic causes of BSS should be considered as a cause of BSS. BSS produced by a herniated cervical disc is extremely rare and is often misdiagnosed.

Atypical presentation of tight filum terminale with thoracic disc herniation: a case report.

BACKGROUND: Tight filum terminale is a rare and challenging condition to diagnose because it presents with nonspecific symptoms and unclear imaging findings. This report documents an atypical case of tight filum terminale. CASE PRESENTATION: The patient was a previously healthy Asian 18-year-old male presenting with recurrent upper extremity and back pain, initially treated as nonspecific musculoskeletal pain. Notably, the patient's symptoms were inconsistent with the dermatome, showing no correlation with his skin's sensory innervation areas. In contrast to typical tight filum terminale presentations focused on lower extremity and lumbar region disturbances, this patient experienced pain and weakness predominantly in the upper extremities and back, hypothesized to result from traction myelopathy exacerbated by thoracic disc herniation. Investigations including blood and nerve function tests were inconclusive. However, a magnetic resonance imaging scan revealed a combination of tight filum terminale and tiny thoracic disc herniation. A diagnosis of tethered spinal cord syndrome was confirmed following further tests and imaging. The filum terminale was surgically removed, resolving the symptoms at a 7-month follow-up. CONCLUSIONS: This case underlines the importance of including tight filum terminale as a differential diagnosis in cases of unexplained upper or lower extremity pain. Primary care practitioners, particularly those managing undefined symptoms, should consider tight filum terminale in their diagnostic approach.

Lumbar degeneration and quality of life in patients with lumbar disc herniation: a case-control long-term follow-up study.

BACKGROUND AND PURPOSE: Adults treated surgically for lumbar disc herniation in adolescence have a higher degree of lumbar disc degeneration than controls. We aimed to establish whether the degree of lumbar degeneration differs at diagnosis or at follow-up between surgically and non-surgically treated individuals. METHODS: We identified individuals with a lumbar disc herniation in adolescence diagnosed with magnetic resonance imaging (MRI) and contacted them for follow-up MRI. Lumbar degeneration was assessed according to Pfirrmann, Modic, and total end plate score (TEP score). Patient-reported outcome measures at follow-up comprised the Oswestry Disability Index (ODI), EQ-5D-3-level version, 36-Item Short Form Health Survey (SF-36), and Visual Analogue Scale (VAS) for back and leg pain. Fisher's exact test, Mann-Whitney U tests, Wilcoxon tests, and logistic regression were used for statistical analysis. RESULTS: MRIs were available at diagnosis and after a mean of 11.9 years in 17 surgically treated individuals and 14 non-surgically treated individuals. Lumbar degeneration was similar at diagnosis (P = 0.2) and at follow-up, with the exception of higher TEP scores in surgically treated individuals at levels L4-L5 and L5-S1 at follow-up (P ≤ 0.03), but this difference did not remain after adjustment for age and sex (P ≥ 0.8). There were no significant differences in patient-reported outcome measures between the groups at follow-up (all P ≥ 0.2). CONCLUSION: Adolescents with a lumbar disc herniation have, irrespective of treatment, a similar degree of lumbar degeneration at the time of diagnosis, and similar lumbar degeneration and patient-reported outcomes at long-term follow-up.

Pediatrics severe low back pain by disc herniation: an uncommon entity.

BACKGROUND: Common severe back pain due to disc herniation is rare in the paediatric population which involves children under eighteen years of age. Paediatric lumbar disc herniation (LDH) cannot be considered the same disease as in adults, as it has potentially different natural and clinical backgrounds. The treatment of pediatric LDH is the other particularity of this condition. Indeed, in children, delaying surgery for a conservative treatment is justified. We report 3 cases treated in 8 years. CASE PRESENTATION: Three patients, two of whom were 14 years of age and one 17 years of age, were admitted for L5 or S1 lumbosciatica. A CT scan showed a lumbar disc herniation L5S1 associated with bi-isthmic lysis (and a transitional abnormality in 1 case or spina bifida occulta in 1 other case). The last patient had an magnetic resonance imaging (MRI) that showed a herniated L4L5 disc. The diagnosis of low back pain disc herniation was retained in two patients and that of disabling low back disc in one patient. Percutaneous discolysis in the two hyperalgesic cases and epidural corticosteroid infiltration in the disabling case were effective on lumbosciatica. CONCLUSION: Paediatric common lomw back pain caused by a disc herniation with a hyperalgic or disabling character posed a therapeutic problem which were solved by the invasive approaches that must be given priority nowadays with children.

Predictors of successful treatment after transforaminal epidural steroid injections in patients with lumbar disc herniation.

BACKGROUND: Epidural steroid injections are common procedures used to treat lumbosacral radicular pain due to lumbar disc herniation (LDH). It is crucial for the clinician to anticipate which patients can benefit from interventional treatment options. OBJECTIVE: This study aimed to examine the effect of radiological and clinical parameters on lumbar transforaminal epidural steroid injections (TFESI)/local anesthetic injection outcomes in patients with LDH. METHODS: This study included 286 patients with LDH (146 males and 140 females). All patients received a fluoroscopically guided TFESI (triamcinolone acetonide 40 mg, lidocaine 2%, and 2.5 ml of physiological saline). Patients were evaluated according to radicular pain, the Oswestry Disability Index (ODI) and the Hospital Anxiety and Depression Scale at baseline and 3 months after the injections. Demographic, clinical and magnetic resonance imaging (MRI) findings were recorded to assess the predictive factors for TFESI outcomes. Pfirrmann Grades 1 and 2 were classified as low-grade nerve root compression and Grade 3 was classified as highgrade nerve root compression. RESULTS: Compared to baseline measurements there were significant improvements in radicular pain, ODI score, Laseque angle, and Schober test scores 3 months after injection. Improvements of at least 50% in radicular pain relief and the ODI functionality index were (n= 214) 82%, (n= 182) 70% respectively at 3 months. Correlation analyses revealed that a shorter duration of symptoms, lowgrade nerve root compression and foraminal/extraforaminal location on MRI findings were associated with a favorable response. CONCLUSIONS: Lowgrade nerve root compression was a predictor of a favorable response to TFESI.

Intramuscular paravertebral oxygen-ozone therapy for chronic neck pain and low back pain: evaluation of 6-month clinical outcomes.

Spinal pain is recognized as the most common cause of disability, work absenteeism and need of healthcare services worldwide. Although many strategies have been developed for conservative treatment of spinal pain, its increasing prevalence diagnosis highlights the need for new treatments. Oxygen-ozone (O2-O3) therapy is considered to be an alternative therapy due to its analgesic and anti-inflammatory effects. This retrospective study evaluated the effects of O2-O3 intramuscular paravertebral injections in 76 patients with chronic neck pain or low back pain, in terms of pain and disability reduction, quality of life improvement, and analgesic drug intake. Patients were evaluated before, at the end of the treatment, and at 1, 3 and 6 months after the last treatment, using Numeric Rating Scale, Neck Disability Index or Oswestry Disability Index, and Short Form-12 Health Survey. There were significant beneficial effects of O2-O3 therapy in reducing pain and disability reduction and improving quality of life during the 6-month follow-up period. O2-O3 therapy was associated with a reduction in analgesic drug intake at each assessment. Our results allow us not only to support treatment with O2-O3 intramuscular paravertebral injections as a safe and beneficial treatment for chronic low back pain, but also to consider it as a valuable conservative therapy for patients with chronic neck pain.

A Method of Predicting Posture-related Pain Using Biomechanical Parameters for Patients with Lumbar Spinal Disc Herniation.

Lumbar spinal disc herniation is a disease in which the protruding nucleus pulposus presses on the nerve due to actions that place loads on the disc, causing pain in the lower back and lower limbs. About 80% of treatments of disc herniation are conservative treatments, and although it is necessary to live with pain for a long time, there have been no studies that clearly define the relationship between pain and biomechanical parameters. In this study, we proposed a method of identifying biomechanical parameters that predict posture-related pain in patients with lumbar spinal disc herniation. The pain values were quantitatively evaluated by the Numerical Rating Scale (NRS) and the biomechanical parameters were analyzed by OpenSim. Lasso regression was performed to narrow down the biomechanical parameters that were related to pain and derive the mathematical model of the relationship. Therefore, many of the parameters of the obtained mathematical model were related to the lumbar spine and were consistent with areas that be related to lumbar spinal disc herniation.

N-Acetyl Cysteine as an Add-on Therapy is Useful in Treating Acute Lumbar Radiculopathy Caused by Disc Herniation: Results of a Randomized, Controlled Clinical Trial.

BACKGROUND: Available experimental and clinical evidence indicates that N-Acetyl cysteine (NAC) may have an analgesic role in specific pain conditions, particularly neuropathic pain. Thus, we hypothesized that NAC supplementation might be also helpful in decreasing pain and improving pain-related disability in patients with acute radiculopathy. We designed this study to investigate the potential use of NAC-adjunctive treatment to Nonsteroidal Anti- Inflammatory Drugs (NSAIDs) in patients with acute radiculopathy secondary to lumbar intervertebral disc herniation. METHODS: Sixty-two patients diagnosed with acute lumbar radiculopathy associated with disc herniation were randomly allocated to the NAC or the placebo groups. Besides naproxen at a dose of 500 mg twice a day, participants based on their allocation group started with NAC or matched placebo at a dose of 600 mg twice a day for eight weeks. The pain severity, measured by the Visual Analog Scale (VAS), and pain-related disability measured by the Oswestry Disability Index (ODI) were measured at baseline and weeks 2, 4, and 8 of treatment. Global improvement of symptoms rated by Patient and Clinical Global Impressions of Change (PGIC and CGIC) was also recorded at the end of week 8. All analyses were conducted on an Intentionto- Treat (ITT) analysis data set. RESULTS: A comparison of the VAS and ODI scores at weeks 2 and 4 of the treatment between the two groups did not show a significant difference. In contrast, from week 4 to week 8, we noticed a significantly greater reduction in the mean VAS and ODI scores in the NAC group compared to the placebo group (p-value <0.001 for both variables). In parallel with these results, also, more NAC-treated than placebo-treated patients achieved treatment success defined as ''very much'' or ''much improved'' on CGIC and PGIC scales, and these differences reached a significant level (p-value = .011 and p-value = .043). CONCLUSIONS: This study suggested that NAC might be a relevant candidate for adjunct therapy in managing acute lumbar radiculopathy. Additional clinical trials are needed to validate these findings.

Cauda Equina Syndrome in a Military Personnel: A Case Report.

Cauda equina syndrome is a rare but severe neuro-spinal disorder commonly caused due to lumbar disc herniation, which occurs mostly at lower levels of L4-S1. We report a case of 38-year-old male soldier deployed on a foreign mission who presented to a level 1 military hospital 4 months back with complaints of decreased movement of bilateral lower limbs and severe low back pain radiating to the right lower limb for 2 hours. He was referred to a higher centre and diagnosed with cauda equina syndrome due to massive disc herniation at levels L2-L3. He underwent laminotomy and discectomy of the extruded intervertebral disc after 48 hours. On subsequent follow-up, his bladder and lower limbs sensations were normal however, he had bowel incontinence, hypotonia, hyporeflexia, and no significant improvement in power. Hence, early diagnosis, referral, and timely intervention affect the outcomes in a cauda equina syndrome patient. Keywords: case reports; cauda equina syndrome; disc herniation; low back pain; military personnel.

Effect of an intraoperative periradicular application of platelet-rich fibrin (PRF) on residual post-surgical neuropathic pain after disc herniation surgery: study protocol for NeuroPRF, a randomized controlled trial.

BACKGROUND: The prevalence of post-surgical lumbar neuropathic radiculopathy is approximately 30%. Poor response to the recommended treatments for neuropathic pain, namely antidepressants and/or gabapentinoids, requires the development of new techniques to prevent chronic pain. One such well-tolerated technique is the administration of autologous plasma enriched in platelets and fibrin (PRF). This approach is largely used in regenerative medicine owing to the anti-inflammatory and analgesic properties of PRF. It could also be an interesting adjuvant to surgery, as it reduces neurogenic inflammation and promotes nerve recovery, thereby reducing the incidence of residual postoperative chronic pain. The aim of the present study is to evaluate the benefit of periradicular intraoperative application of PRF on the residual postsurgical neuropathic pain after disc herniation surgery. METHODS: A randomized, prospective, interventional, controlled, single-blind study with evaluation by a blind outcome assessor will be performed in Strasbourg University Hospital. We will compare a control group undergoing conventional surgery to an experimental group undergoing surgery and periradicular administration of PRF (30 patients in each arm). The primary outcome is the intensity of postoperative neuropathic radicular pain, measured by a visual analog scale (VAS) at 6 months post-surgery. The secondary outcomes are the characteristics of neuropathic pain (NPSI), the quality of life (SF-12 and PGIC), the presence of anxiety/depression symptoms (HAD), and the consumption of analgesics. We will also carry out transcriptomic analysis of a panel of pro- and anti-inflammatory cytokines in blood samples, before surgery and at 6 months follow-up. These gene expression results will be correlated with clinical data, in particular, with the apparition of postoperative neuropathic pain. DISCUSSION: This study is the first randomized controlled trial to assess the efficacy of PRF in the prevention of neuropathic pain following surgery for herniated disc. This study addresses not only a clinical question but will also provide information on the physiopathological mechanisms of neuropathic pain. TRIAL REGISTRATION: This study is registered at ClinicalTrials.gov: NCT05196503 , February 24, 2022.

Bone cement distribution may significantly affect the efficacy of percutaneous vertebroplasty in treating symptomatic Schmorl's nodes.

PURPOSE: Percutaneous vertebroplasty(PVP) has been widely used in treating symptomatic Schmorl's nodes(SNs). However, there were still some patients with poor pain relief. At present, there is a lack of research to analyze the reasons for poor efficacy. METHODS: Review the SNs patients treated with PVP in our hospital from November 2019 to June 2022, collect their baseline data. Reverse reconstruction software was used to calculate the filling rate of bone edema ring(Rf). NRS score was used to evaluate pain and ODI to evaluate function. The patients were divided into remission group(RG) and non remission group(n-RG) according to symptom. In addition, according to the Rf, they were divided into excellent, good and poor groups. Differences between groups were investigated. RESULTS: A total of 26 vertebrae were included in 24 patients. When grouped according to symptoms, patients in n-RG were older, and surgical segments were tend to locate in lower lumbar spine. The proportion of Poor distribution was significantly higher. When grouped according to the cement distribution, the preoperative NRS and ODI of the three groups were comparable, but the NRS and ODI of Poor group were significantly worse than the Excellent and Good groups postoperatively and at the last follow-up. CONCLUSIONS: The cement distribution may significantly affect the efficacy of PVP in treating symptomatic SNs. We suggest that the bone edema ring should be filled as fully as possible to ensure the efficacy. In addition, advanced age and low lumbar lesions are also adverse factors for clinical outcomes.

Novel Physical Examination Tests for the Diagnosis of Chronic Sacroiliac Joint Dysfunction and Differentiate It From Lumbar Disc Herniation.

BACKGROUND: Traditional sacroiliac joint (SIJ) provocation tests have been used to diagnose SIJ pain. However, this can simply be changed to chronic SIJ dysfunction (cSIJD) manifests as mechanical changes in the pelvis and lower extremities in addition to pain. A novel composite of physical examinations based on the iliac pronation, pubic tubercle tenderness, and plantar fascia tenderness tests (IPP triple tests) was designed for the diagnosis of cSIJD. OBJECTIVES: To evaluate IPP triple tests in the diagnosis of cSIJD and differential diagnosis from lumbar disc herniation (LDH) in comparison with traditional provocation tests. STUDY DESIGN: Prospective single-blind controlled study. SETTING: This study was conducted at the Department of Spine and Spinal Cord Surgery of China Rehabilitation Research Center in Beijing, China. METHODS: One hundred and sixty-six patients were assigned into the cSIJD group, LDH group, or healthy control group. The cSIJD diagnosis was confirmed by SIJ injection. The diagnosis of LDH was confirmed according to the 2014 North American Spine Association diagnosis and treatment guidelines for LDH. All patients were examined with IPP triple tests and traditional provocation tests. The sensitivity, specificity, positive and negative likelihood ratios, and areas under the curve (AUCs) were used to evaluate the diagnostic accuracy of the composites or single of the IPP triple tests, and traditional provocation tests. The Delong's test was used for the comparison among AUCs. The kappa analysis was used for the IPP triple tests and traditional provocation tests compared with the reference standard (REF). The independent t test and chi-square test were used to analyze the influence factors (i.e., age, gender), and group on diagnostic accuracy. RESULTS: There was no statistical difference in gender (chi-squared = 0.282, P = 0.596) and age (F = 0.096, P = 0.757) between the 3 groups. The AUC of the iliac pronation test was 0.903 when it was used alone; the AUC of the novel composites of the IPP triple tests was 0.868 (95% confidence interval [CI] = 0.802-0.919); and the diagnostic accuracy of the traditional provocation test was relatively low (AUC = 0.597, 95% CI = 0.512-0.678). The diagnostic accuracy of the IPP triple tests was higher than that of the traditional provocation test, P < 0.05. Kappa consistency comparison showed that the kappa value between the IPP triple tests and the REF was 0.229, the kappa between the traditional provocation test and the REF was 0.052. The age of the patients with inaccurate diagnosis was higher than that of the patients with accurate diagnosis in both methods (traditional tests, P = 0.599; IPP:P = 0.553). Different types of diseases (groups) affect the accuracy of diagnosis, the proportion of inaccuracy of traditional provocation tests was higher than that of the IPP triple tests (77.8% vs 23.6%) in cSIJD, while the 2 methods have high differential diagnostic accuracy in LDH (96.77%) and control groups (97.56%). LIMITATIONS: Small size of LDH patients and differences in physical tests among examiners. CONCLUSIONS: The novel composites of IPP triple tests have higher accuracy than the traditional provocation tests in diagnosing cSIJD and both have good accuracy in differentiating cSIJD from LDH. IPP triple tests may be an alternative physical examination for clinical screening of cSIJD.

Lumbar Disc Herniation: Diagnosis and Management.

Lumbar disc herniations are common causes of lower back pain, neurological dysfunction, and buttock/leg pain. Herniation refers to the displacement of the nucleus pulposus of the intervertebral disc through the annulus fibrosus, thereby causing pressure on the neural elements. The sequalae of lumbar disc herniations range in severity from mild low back and buttock pain to severe cases of inability to ambulate and cauda equina syndrome. Diagnosis is achieved with a thorough history and physical examination along with advanced imaging. Treatment plans are dictated by corresponding patient symptoms and examination findings with their imaging. Most patients can experience relief with nonsurgical measures. However, if symptoms persist or worsen, surgery may be appropriate.

Comparison of magnetic resonance imaging findings among sciatica patients classified as centralizers or non-centralizers.

OBJECTIVE: To compare if the degenerative findings from MRI differ between the sciatica patients classified as centralizers (CEN) and non-centralizers (Non-CEN) according to the McKenzie Method of mechanical diagnosis and therapy. STUDY DESIGN: A cross-sectional study. METHODS: Patients (N = 100) referred to a spine clinic of a single tertiary hospital for specialist consultation for sciatica. The McKenzie-based assessment was performed by the mechanical diagnosis and therapy-trained physiotherapists. Clinical data and prevalence of lumbar MRI findings were compared between the groups. RESULTS: There was no significant difference in leg pain intensity between the groups. The Non-CEN had significantly more intense back pain, mean 56 (SD 30) and were more disabled 44 (SD 15) compared to the CEN mean 41 (SD 25) and mean 31 (11), measured with a visual analogue scale (0-100), and the Oswestry Disability Index (0-100), respectively. The CEN had more severe degenerative findings on MRI than the Non-CEN: vertebral end-plate changes were 63% and 43%; mean Pfirrmann's disc degeneration lumbar summary score was 12.8, and 10.6; and severity score of total damage was 12.0 and 10.1, respectively. There were differences neither in disc contour changes nor nerve root stenosis on MRI. CONCLUSIONS: Sciatica patients classified as non-centralizers had significantly more severe back pain, and were significantly more disabled than centralizers, who instead had more severe degenerative findings on MRI. Thus, classification to non-centralizers by the McKenzie method seems not predict higher incidence of degenerative findings on MRI compared to centralizers.

Usefulness of discography, discoblock and a new mechanical method for identifying a painful segment/disc.

BACKGROUND: We previously described a procedure for eliciting deep spatial discrimination of individual segments in the healthy lumbar spine of normal subjects: the percutaneous mechanical provocation (PMP) test. Our goal was to devise a method for accurate identification of the spinal level of pathology in chronic low back pain (CLBP). In the present study, we validated the PMP test, using a subgroup of CLBP patients with isthmic spondylolisthesis (IS). Because there is clinical consensus that IS back pain originates in the slipped segment/disc, the level of pathology can be directly compared to the result of the PMP test. The test is agnostic with respect to the underlying pathological mechanism, and therefore might be useful in identifying the involved segment(s) irrespective of the painful structure. METHODS: In 37 patients with confirmed IS (slippage 3-15mm), we compared sensitivity between the PMP test, the widely used provocative discography test and the discoblock test. RESULTS: The PMP test reliably identified the slip level in patients with IS, with sensitivity of 92%. Accepting the slipped disc as the origin of pain in IS, the sensitivity of the provocative discography and discoblock tests were 49% and 35%, respectively: i.e., too low to be contributive in clinical practice. CONCLUSIONS: The PMP test reliably identified the origin of localized pain in IS as the slip level, but should be used with care in CLBP patients in selecting discogenic pain patients for fusion surgery, since the specificity of the test is not known and it may be positive for any origin of localized pain.

Neoplastic malignant cord compression mimicking low back pain: A case report.

BACKGROUND: The point prevalence of Cauda Equina Syndrome (CES) as a cause of Low Back Pain (LBP) is estimated at 0.04% in primary care, and it is reported as a complication in about 2% of patients with disc herniation. Compression of the cauda equina usually occurs as a result of disc prolapse. However, CES may be caused by any space-occupying lesion, including spinal stenosis, neoplasms, cysts, infection, and osteophytes. First contact physiotherapists may encounter patients with early CES, as the clinical presentation of CES can mimic non-specific LBP. CASE PRESENTATION: This case report presents the medical history, diagnostic tests and relevant clinical data of a 52-year-old man complaining of LBP. The patient's medical history, his symptoms and the clinical findings led to the identification of a number of red flags (i.e. risk factors) suggestive of a non-musculoskeletal condition. The patient was referred to the emergency department for further investigation. Having undergone several diagnostic tests, the patient was diagnosed with CES due to malignancy. CONCLUSIONS: This case report highlights the importance of differential screening throughout the treatment period, in order to identify red flags that warrant further investigation and a referral to an appropriate specialist. Physiotherapy screening should include clinical reasoning, careful analysis of clinical presentation and symptom progression, in addition to appropriate referral for medical assessment and diagnostic imaging, if necessary.
