Background/Objectives: Low back pain (LBP) is the leading cause of disability in Saudi Arabia and contributes substantially to healthcare utilisation, reduced quality of life, and lost productivity. This guideline provides nationally standardised, evidence-based recommendations for the assessment and management of non-specific LBP and sciatica in adults, adapted to the clinical and health-system context in Saudi Arabia. Methods: A multidisciplinary Task Force developed the guideline using the GRADE ADOLOPMENT approach, using NICE guideline NG59 as the primary evidence source. One additional clinical question was formulated to address pain neuroscience education, informed by a relevant systematic review. Update literature searches were conducted in PubMed, Embase, and the Cochrane Library (2016–2022). The evidence was appraised using GRADE, and recommendations were formulated through structured Evidence-to-Decision deliberations and consensus voting. Results: The Task Force addressed eleven clinical questions in this guideline. Strong recommendations were provided for the use of validated risk assessment tools (very low certainty of evidence) and stratified management (moderate certainty of evidence). Conditional recommendations were made for indications for imaging, pharmacological treatment for sciatica, psychological interventions, multidisciplinary return to work programmes, epidural injections, prognostic value of image-concordant pathology, spinal decompression, radiofrequency denervation, and pain neuroscience education, with certainty of evidence ranging from very low to low. Conclusions: The findings indicate that management of non-specific LBP and sciatica in Saudi Arabia should be guided by clinical assessment, with restricted use of imaging, careful selection of pharmacological treatments, and appropriate use of psychological, multidisciplinary, and procedural interventions.

Background/Objectives: Adult spinal deformity (ASD) is increasingly prevalent due to an ageing population and is associated with significant pain, disability, and reduced quality of life. While surgery is often considered for severe deformities, many patients are either unsuitable for major corrective procedures or prefer conservative care. This narrative review synthesizes the current evidence on nonoperative management strategies for ASD. Methods: A literature search on the PubMed and Cochrane databases identified relevant studies published up to 25 October 2025. Medical Subject Headings and keywords related to nonsurgical ASD management were used. Eligible studies included nonsurgical series with a minimum of 12 months’ follow-up, while case reports were excluded. Results: Seven studies met our inclusion criteria: three on bracing, three on physiotherapy and combined physical and cognitive rehabilitation programmes, and one on transforaminal epidural steroid injections (ESIs). Bracing was effective in slowing the curve progression rate. One study showed that the progression rate decreased from 1.47°/year to 0.24° for degenerative scoliosis (p < 0.0001) and from 0.70°/year to 0.24° for idiopathic scoliosis (p = 0.03). Another study showed that there was no statistically significant difference in the Cobb angle or anticipated worsening when comparing the initial measurement with the final control after treatment (p = 0.973). Finally, a third study reported reduced back pain, with Roland–Morris scores improving from 3.3 to 2.0 (p < 0.001) at 18 months. Physiotherapy and multidisciplinary rehabilitation programmes appeared to be effective in significantly reducing pain and disability levels. One study found that Oswestry Disability Index (ODI) scores improved from 39.5 to 31.8 (p < 0.001), while back pain, measured using the Numeric Pain Rating Scale (NPRS), improved from 58.4 to 42.1 (p < 0.001), with 51% achieving minimal clinically important change (MCIC). Another study reported ODI reductions from 38 to 17.6 and pain scores from 6.5 to 2.2 (p < 0.001), while in a third study, the “Koshimagari Exercise” programme yielded MCIDs in the ODI for 42% of patients. Finally, ESIs provided significant pain relief for at least a month in over half of the patients with degenerative scoliosis and radiculopathy, with diminishing effects throughout the first 2 years. More specifically, 37.2% of patients had a successful outcome at one year post-injection and 27.3% at 2 years (p < 0.01). Conclusions: Our study suggests that bracing, physiotherapy, and multidisciplinary rehabilitation programmes, as well as ESIs, can serve as effective short term alternatives for patients with ASD who are either unsuitable for surgery or do not wish to pursue it. As such, this review provides valuable evidence-based insights that can guide clinicians in developing a treatment plan and lay the foundations for establishing a novel pathway for this specific subgroup of patients with ASD.

Background/Objectives: While epidural and periradicular corticosteroid injections are well-established treatments for degenerative spinal conditions, intrathecal administration of glucocorticoids remains uncommon and under-researched. To our knowledge, this is the first large contemporary dataset on intrathecal triamcinolone in degenerative lumbar disorders. This study retrospectively analyzes clinical outcomes and complication rates associated with this treatment. Methods: We reviewed patients who received intrathecal injections of triamcinolone for lumbar degenerative spinal diseases between May 2023 and June 2024. Data were extracted from electronic records and included demographics, indication, application method (freehand or CT-guided), dosage, symptom relief, and complications. Results: A total of 722 intrathecal injections were performed (499 patients). The most common indication was lumbar spinal canal stenosis (94.0%). Punctures were performed freehand in 68.4% of the injections; 80 mg of triamcinolone was administered in 71.2%. Follow-up data were available for 528 injections. After 87.3% of these, symptom improvement (binary yes/no) after injection was reported. Duration of benefit was documented after 144 injections: 39.6% reported a relief lasting up to six months, and 25% up to one month. Four complications (0.6%) occurred: one post-puncture headache, one pain aggravation, one case of shortness of breath, and one intracranial subdural hygroma. All were managed conservatively. Conclusions: Despite limited data quality, including missing/non-standardized follow-up and the lack of standardized pain scales for follow-up, this large retrospective cohort provides preliminary evidence that intrathecal triamcinolone may be a safe and effective treatment option for lumbar degenerative spinal disorders, with pain relief observed in the majority of cases. Given the inherent limitations of retrospective Level IV evidence, prospective controlled studies are warranted to further evaluate its role compared to other interventional pain therapies.

Spinal cord injury (SCI) often results in long-term locomotor impairments, and strategies to enhance functional recovery remain limited. While epidural electrical stimulation (EES) has shown clinical promise, our understanding of the mechanisms by which it improves function remains incomplete. Here, we use genetic tools in an animal model to perform neuromodulation and treadmill rehabilitation in a manner similar to EES, but with the benefit of the genetic tools and animal model allowing for targeted manipulation, precise quantification of the cells and circuits that were manipulated, and the gathering of extensive kinematic data. We used a viral construct that selectively transduces large diameter afferent fibers (LDAFs) with a designer receptor exclusively activated by a designer drug (hM3Dq DREADD; a chemogenetic construct) to increase the excitability of large fibers specifically, in the rat contusion SCI model. As changes in locomotion with afferent stimulation can be subtle, we carried out a detailed characterization of the kinematics of locomotor recovery over time. Adult Long-Evans rats received contusion injuries and direct intraganglionic injections containing AAV2-hSyn-hM3Dq-mCherry, a viral vector that has been shown to preferentially transduce LDAFs, or a control with tracer only (AAV2-hSyn-mCherry). These neurons then had their activity increased by application of the designer drug Clozapine-N-oxide (CNO), inducing tonic excitation during treadmill training in the recovery phase. Kinematic data were collected during treadmill locomotion across a range of speeds over nine weeks post-injury. Data were analyzed using a mixed effects model chosen from amongst several models using information criteria. That model included fixed effects for treatment (DREADDs vs. control injection), time (weeks post injury), and speed, with random intercepts for rat and time point nested within rat. Significant effects of treatment and treatment interactions were found in many parameters, with a sometimes complicated dependence on speed. Generally, DREADDs activation resulted in shorter stance duration, but less reduction in swing duration with speed, yielding lower duty factors. Interestingly, our finding of shorter stance durations with DREADDs activation mimics a past study in the hemi-section injury model, but other changes, including the variability of anterior superior iliac spine (ASIS) height, showed an opposite trend. These may reflect differences in injury severity and laterality (i.e., in the hemi-section injury the contralateral limb is expected to be largely functional). Furthermore, as with that study, withdrawal of DREADDs activation in week seven did not cause significant changes in kinematics, suggesting that activation may have dwindling effects at this later stage. This study highlights the utility of high-resolution kinematics for detecting subtle changes during recovery, and will enable the refinement of neuromechanical models that predict how locomotion changes with afferent neuromodulation, injury, and recovery, suggesting new directions for treatment of SCI.

Background: As means of addressing ongoing challenges in accessing publicly funded specialist care, new models of care have been trialled. One such approach is using physiotherapists in advance practice roles, who in collaboration with other health professionals, act as an initial orthopedic point of contact and coordinate care. This research investigated the impact of a model of care, the Spinal Virtual Clinic Model, implemented for the first time in South Australia, using advanced practice physiotherapists in a large metropolitan hospital in South Australia. Although formally named the “Spinal Virtual Clinic” by the health service, this model does not involve direct patient contact and differs from traditional virtual or telehealth clinics. Instead, it is best understood as a physiotherapy-led referral triage and management service. Methods: This research was conducted in two stages. Stage 1 was a retrospective clinical audit of sequential patients triaged to the Spinal Virtual Clinic, as well as a follow up audit to capture any subsequent engagement with the Orthopaedic Spinal Service following the initial Spinal Virtual Clinic correspondence. Data were descriptively analysed. In Stage 2, semi-structured interviews were conducted with patients from the Spinal Virtual Clinic to explore their perspectives on this model of care. The interviews were transcribed verbatim and independently analysed using thematic analysis. The sequential use of quantitative and qualitative approaches enabled us to both describe engagement with this model of care and better understand the underlying perspectives. Results: Three hundred and nine referrals were triaged to the physiotherapy-led spinal virtual clinic over a six-month period from 1 January 2021 to 30 June 2021. Majority of referrals were triaged as low acuity did not need formal spinal specialist review and could be managed safely in primary care. Therapist-led active management strategies (80.8%), trial of neuropathic medication (35.6%) closely followed by advice regarding targeted spinal injections (foraminal and epidural), were the most common conservative management strategies recommended. Only a small proportion needed surgical review. Interviews with eleven patients revealed that while many valued the convenience, timely advice, and reassurance offered by the service, others expressed confusion about the referral process and disappointment at not seeing a specialist. A key recommendation identified was improved communication, including providing patients with direct feedback alongside general practitioner correspondence. Conclusions: This research, underpinned by quantitative and qualitative research, has showcased the potential of this model of care, the spinal virtual clinic, to have a positive impact on improving access and reducing the burden on the health system for low acuity patients. As historical models of care become unsustainable and obsolete, alternative models of care can be implemented in health care settings where outpatient demand significantly exceeds capacity.

Background and Clinical significance: Single-shot spinal anesthesia for intrapartum Cesarean section has recently been incriminated in carrying a high risk of high neuraxial block (HNB) occurrence in parturients receiving labor epidural analgesia. The so-called volume effect of the epidurally injected solution causes a contraction of the dural sack and unexpected HNB. Case presentation: We present two cases of HNB in parturients receiving epidural analgesia. The first case describes the 36-year-old patient G3P2, who was administered a repeated rescue analgesia single-shot spinal injection with low-dose local anesthetic (levobupivacaine, 3 mg) following non-functional combined spinal–epidural analgesia. The second case describes the 28-year-old parturient G1P0, who experienced HNB after single-shot spinal anesthesia with hyperbaric bupivacaine (7.5 mg) following labor epidural analgesia. Conclusions: Intrathecal administration of local anesthetic for the purpose of spinal analgesia or anesthesia in a parturient with epidural analgesia can cause unexpected HNB and could occur even at low doses of intrathecally administered medications. The interplay of numerous variables and circumstances in the specific case can result in the occurrence of HNB. We assume that in our first case, the volume effect and repeated dural puncture, and in the second case, the low height of the parturient coupled with the volume effect, played significant role in the occurrence of HNB.

Background/Objectives: Sarcopenia is defined by the progressive loss of muscle mass, strength, and/or physical performance associated with aging. Radiofrequency ablation (RFA) of the medial branch nerves is a well-established and effective treatment for lumbar facetogenic pain. While sarcopenia is associated with poor outcomes following epidural steroid injections and lumbar spine surgeries, its impact on clinical outcomes in patients undergoing RFA for facetogenic pain remains unexplored. This study aims to evaluate the influence of sarcopenia on treatment outcomes in this patient cohort. Methods: Patients were classified into sarcopenia (n = 35) and non-sarcopenia groups (n = 67) based on predefined psoas muscle index (PMI) thresholds. The primary outcomes included changes in back pain intensity and the proportion of responders at 1, 3, and 6 months following RFA. The secondary outcome was to identify demographic, clinical, and sarcopenia-related factors predictive of treatment response at each follow-up interval. Results: Both groups demonstrated statistically significant improvements in pain scores compared to baseline at all follow-up points. However, the median pain scores at 3 months post-RFA remained significantly higher in the sarcopenia group. Despite this, the proportion of responders did not differ significantly between the two groups at any time point. At 3 months, the absence of prior spinal surgery was identified as a significant predictor of treatment response. At 6 months, favorable outcomes were significantly associated with the absence of diabetes, no history of spinal surgery, and a higher PMI. Conclusions: Sarcopenia may influence the extent of pain improvement following medial branch nerve RFA. Additionally, patient-specific factors, such as diabetes, prior spinal surgery, and PMI, should be considered when predicting treatment outcomes. Full article

The erector spinae plane (ESP) block is a widely used technique for perioperative analgesia. It involves the infiltration of anesthetics into the interfacial plane between the erector spinae muscle and the transverse processes of the vertebrae. In veterinary medicine, this technique has been adapted for different species, but there are no cadaveric studies in cats. This study describes the ultrasound-guided lumbar ESP-block technique and evaluates the spread of two volumes of dye in feline cadavers. Injections were performed at the second lumbar vertebra (L2) level using 0.6 mL/kg (high volume [HV]) and 0.4 mL/kg (low volume [LV]) of methylene blue bilaterally. After anatomical dissection, the distribution of the dye, the staining of the spinal nerve branches, and the presence of dye in the epidural space were recorded. The results demonstrated that the HV treatment provided wider longitudinal distribution, staining the dorsal branch of the spinal nerves in an average of five segments per injection, without extravasation into the epidural space. It is concluded that the HV treatment promotes efficient multisegmental spread in feline cadavers. Full article

Introduction: Epidural steroid injections (ESIs) are a common interventional treatment for managing spinal pain complaints. Despite their widespread use, practice patterns among physicians performing ESIs vary significantly. This study aimed to evaluate preprocedural imaging review by pain physicians who perform ESIs in the cervical, thoracic, and lumbar spine. Methods: A survey was distributed to a cohort of physicians who regularly perform ESIs. The survey comprised questions regarding preprocedural imaging review before performing ESIs in the cervical, thoracic, and lumbar spine. The respondents included a diverse group of pain management physicians from various specialties and practice settings. Results: The results revealed that the majority of interventional pain management physicians personally interpret their own imaging, followed by a significant percentage of physicians who rely on the radiology reports. There were no physicians who did not perform any imaging review prior to ESIs. Whereas all respondents reported some form of imaging review, only 63.86%, 53.75%, and 64.44% reviewed the actual images prior to cervical, thoracic, and lumbar access, respectively. Conclusions: This survey provides initial data regarding imaging reviews among physicians who perform ESIs. Our results demonstrate that physicians treat imaging review as an essential component of the preprocedural process for performing ESIs, as all physicians reported that they perform some form of imaging review before performing ESIs. However, there is only partial adherence to the multidisciplinary working group opinion that segmental imaging should be reviewed for adequacy of space prior to cervical epidural access.

The epidural injection is a medical intervention to inject therapeutics directly into the vicinity of the spinal cord for pain management. Because of its proximity to the spinal cord, imprecise insertion of the needle may result in irreversible damage to the nerves or spinal cord. This study explores enhancing procedural accuracy by integrating a telerobotic system and augmented reality (AR) assistance. Tele-kinesthesia is achieved using a leader–follower integrated system, and stable force feedback is provided using a novel impedance-matching force rendering approach. In this domain, augmented reality employs a magnetic-tracker-based approach for real-time 3D model projection onto the patient’s body, aiming to augment the physician’s visual field and improve needle insertion accuracy. Preliminary results indicate that our AR-enhanced robotic system may reduce the cognitive load and improve the accuracy of ENI, highlighting the promise of AR technologies in complex medical procedures. However, further studies with larger sample sizes and more diverse clinical settings must comprehensively validate these findings. This work lays the groundwork for future research into integrating AR into medical robotics, potentially transforming clinical practices by enhancing procedural safety and efficiency. Full article

The ultrasound-guided cervical plexus plane (US-CPP) block has proven effective in humans; yet its application in dogs remains unexplored. This study aimed to describe a novel US-CPP approach in canines. A local sonoanatomy was mapped, the injection technique was tested, and a gross anatomical dissection (GAD) was performed on one cadaver. The bilateral injectate spread and nerve staining were then evaluated via a CT scan and GAD in the six cadavers. The transducer was aligned parallel to the cervical spine, caudal to the atlas. After identifying the cleidocervical and omotransversarius muscles and the C2-C3 interfascial plane, a spinal needle was inserted in-plane, and 0.15 mL/kg of a dye-contrast solution was injected. CT imaging showed the contrast reaching the C1, C2, and C3 vertebral bodies in 3 out of 12 (3/12), 11/12, and 12/12 injections, respectively, and the C4, C5, and C6 vertebrae in 8/12, 5/12, and 1/12 injections, respectively. No contrast was detected in the epidural space. The C1, C2, C3, C4, and C5 nerves were stained in 3/12, 10/12, 8/12, 2/12, and 0/12 injections, respectively. No significant differences were observed between the groups (p > 0.05). A single US-CPP injection successfully stained the C2 and C3 nerves, indicating the potential clinical applicability, although the injected volume rarely reached C4 and C5. Full article

Background/Objectives: Lumbar degenerative disease is a common age-related condition, with epidural steroid injection (ESI) being a widely employed conservative treatment approach. However, the potential effect of ESI on osteoporosis and fracture risk remains unclear. This study investigated the risk of osteoporotic vertebral compression fractures (OVCFs) in patients with lumbar degenerative disease who underwent ESI treatment. Methods: A cohort of 64 patients who received ESI treatment and a control group of 256 patients were included in this study. Demographic data, clinical characteristics, and follow-up information were collected. Cox proportional hazards models were used to analyze risk factors for OVCF, and subgroup analyses were conducted. Results: OVCF was more common in the ESI group than in the control group (hazard ratio [HR]: 3.49, 95% confidence interval [CI]: 1.06–11.43, p = 0.039). After confounding factors were adjusted for, ESI remained an independent risk factor for OVCF (HR: 4.60, 95% CI: 1.01–20.89, p = 0.048). In a subgroup analysis, lower socioeconomic status was associated with higher OVCF risk (HR: 11.82, 95% CI: 1.06–131.26, p = 0.044). The ESI group had improved short-term pain relief, with nonsignificant long-term effects. Conclusions: Patients with lumbar degenerative disease receiving ESI treatment are at an increased risk of OVCF, particularly those with lower socioeconomic status. These findings underscore the importance of regular bone density monitoring and fracture prevention following ESI treatment. Clinicians should carefully weigh the short-term benefits of ESI against the long-term risks and develop individualized follow-up plans for high-risk patients. Full article

Objectives: Augmented reality (AR) navigation systems are emerging to simplify and enhance the precision of medical procedures. Lumbosacral transforaminal epidural injection is a commonly performed procedure for the treatment and diagnosis of radiculopathy. Accurate needle placement while avoiding critical structures remains a challenge. For this purpose, we conducted a randomized controlled trial for our augmented reality navigation system. Methods: This randomized controlled study involved 28 patients, split between a traditional C-arm guided group (control) and an AR navigation guided group (AR-NAVI), to compare procedure efficiency and radiation exposure. The AR-NAVI group used a real-time tracking system displaying spinal structure and needle position on an AR head-mounted display. The procedural time and C-arm usage (radiation exposure) were measured. Results: All patients underwent successful procedures without complications. The AR-NAVI group demonstrated significantly reduced times and C-arm usage for needle entry to the target point (58.57 ± 33.31 vs. 124.91 ± 41.14, p < 0.001 and 3.79 ± 1.97 vs. 8.86 ± 3.94, p < 0.001). Conclusions: The use of the AR navigation system significantly improved procedure efficiency and safety by reducing time and radiation exposure, suggesting a promising direction for future enhancements and validation.

Background and Objectives: Adequate pain management during early rehabilitation is mandatory for improving the outcomes of patients undergoing total knee arthroplasty (TKA). Conventional pain management, mainly comprising opioids and epidural analgesia, may result in certain adverse effects such as dizziness, nausea, and motor blockade. We proposed a multimodal analgesic (MA) strategy involving the use of peripheral nerve block (NB), periarticular injection (PAI), and intravenous patient-controlled analgesia (IVPCA). This study compared the clinical efficacy and adverse effects of the proposed MA strategy and patient-controlled epidural analgesia (PCEA). Materials and Methods: We enrolled 118 patients who underwent TKA under spinal anesthesia. The patients followed either the MA protocol or received PCEA after surgery. The analgesic effect was examined using a numerical rating scale (NRS). The adverse effects experienced by the patients were recorded. Results: A lower proportion of patients in the MA group experienced motor blockade (6.45% vs. 22.98%) compared to those in the PCEA group on the first postoperative day. Furthermore, a lower proportion of patients in the MA group experienced numbness (18.52% vs. 43.33%) than those in the PCEA group on the first postoperative day. Conclusions: The MA strategy can be recommended for reducing the occurrence of motor blockade and numbness in patients following TKA. Therefore, the MA strategy ensures early rehabilitation while maintaining adequate pain relief. Full article

Epidural administration is the leading therapeutic option for the management of pain associated with lumbar spinal stenosis (LSS), which is characterized by compression of the nerve root due to narrowing of the spinal canal. Corticosteroids are effective in alleviating LSS-related pain but can lead to complications with long-term use. Recent studies have focused on identifying promising medications administered epidurally to affected spinal regions. In this study, we aimed to investigate the effectiveness of harpagoside (HAS) as an epidural medication in rats with LSS. HAS at various concentrations was effective for neuroprotection against ferrous sulfate damage and consequent promotion of axonal outgrowth in primary spinal cord neurons. When two concentrations of HAS (100 and 200 μg/kg) were administered to the rat LSS model via the epidural space once a day for 4 weeks, the inflammatory responses around the silicone block used for LSS were substantially reduced. Consistently, pain-related factors were significantly suppressed by the epidural administration of HAS. The motor functions of rats with LSS significantly improved. These findings suggest that targeted delivery of HAS directly to the affected area via epidural injection holds promise as a potential treatment option for the recovery of patients with LSS.
