Objectives: To present novel strategies in the diagnosis and management of spondylodiscitis in a patient with tetraplegia. Case Presentation: A 44-year-old man presented with increased spasms despite having a SynchroMed II Medtronic for intrathecal infusion of baclofen. The C-reactive protein level was raised. Infection was suspected, but there were no localising signs. Positron Emission Tomography (PET) was performed to identify the focus of infection. PET showed an increased Fluorodeoxyglucose uptake in the L-5 vertebral body and the associated ill-defined soft tissue anteriorly. There was significant erosion and destruction of the S-1 vertebra. Magnetic Resonance Imaging of the lumbo-sacral spine revealed destruction and collapse of the S-1 vertebral body and a 6 cm × 2 cm anterior paravertebral abscess collection. This patient was managed in his home. Intravenous administration of 1 g of Ertapenem daily was provided by community nurses for eight weeks. Blood tests were performed in the community setting, and the patient was monitored by spinal unit doctors. Results: Follow-up CT revealed abnormal soft tissue, expanding and replacing the S-1 vertebral body, with appearances in keeping with an infective process. Using CT guidance and the Madison bone biopsy kit, multiple cores were obtained from the left sacral bone. Four of the five specimens showed no growth after extended incubation. Propionibacterium acnes were isolated after 10 days of incubation from the tissue from the sacral bone biopsy only. A shared decision was made towards active surveillance. Follow-up CT of the abdomen showed a stable appearance of the lumbar and sacral spine. Conclusions: A complex case of spondylodiscitis can be diagnosed and managed while the patient stays mainly in their home, avoiding prolonged admission to the spinal unit, in alignment with the “hospital to community” aspect of the National Health Service’s 10-year Health Plan for England. A diagnostic pathway with PET-CT as the first approach proved useful when the site of infection was unclear. Active surveillance obviated the need for extended periods of antibiotic therapy, which could have led to complications such as antibiotic-induced toxicity and microbial resistance to antibiotics.

Background/Objectives: Non-invasive spinal cord transcutaneous stimulation (scTS) has expanded the therapeutic landscape of spinal cord injury (SCI) rehabilitation, offering potential benefits beyond compensatory approaches to paralysis. Children with SCI are particularly susceptible to developing neuromuscular scoliosis due to trunk muscle paralysis and ongoing skeletal growth, making targeted interventions crucial. As demonstrated in adults and pediatrics with SCI, the ability of scTS to acutely and safely enable an upright posture and trunk control could be leveraged as a therapeutic adjunct. Activity-based locomotor training (AB-LT) alone significantly improves trunk control in children with SCIs; combining it with scTS may enhance outcomes. This pilot study evaluated the safety, feasibility, and cumulative effects of AB-LT combined with scTS on trunk control in children with SCI. Methods: Three children with SCI completed 19 to 64 sessions of combined AB-LT and scTS. Adverse effects were monitored session to session, and trunk control was assessed pre- and post-intervention. Results: Across 130 interventions in three participants, 88.5% of sessions were free from adverse effects. Reported adverse events included autonomic dysreflexia (5.4%), skin redness at electrode sites (4.6%), and headaches (1.5%). No significant impact of scTS on fatigue or central hemodynamic parameters was observed. Post-intervention, all participants demonstrated improved trunk control during quiet and perturbed sitting. Conclusions: These findings provide the first evidence supporting the safety and feasibility of this combinatorial approach in pediatric SCI rehabilitation while emphasizing the importance of monitoring skin integrity and signs of autonomic dysreflexia. This intervention shows potential synergistic benefits, warranting further research to confirm efficacy and optimize therapeutic protocols. Full article

Background/Objectives: Autonomic dysreflexia (AD) is a clinical syndrome affecting persons with spinal cord injury (SCI). The aim of the study was to present the experience of individuals with SCI and AD in Croatia. Single-center questionnaire study. Setting: Faculty of Medicine, University of Rijeka, Rijeka, Croatia. Persons with SCI were divided into those with an SCI at T6 and above (n = 41) and those with an SCI at T7 and below (n = 29). Based on anamnestic data, patients with an SCI at T6 and above were further divided into those with and without self-reported clinical symptoms of AD (respectively: n = 33 and n = 8). Methods: The online survey included 23 questions of various types. It consisted of a general (demographic) section, section with specific questions about AD, and a section on self-assessment and quality of life. Based on the answers, the experience and knowledge of AD among individuals with an SCI in Croatia was assessed. Results: A total of 70 individuals with an SCI completed the whole survey. The average age was 40.6 years. The patients were predominantly male (72.9%) and mostly with a traumatic SCI (84.3%). Of the 70 individuals with an SCI, 35 (50%) reported they were familiar with AD, with the majority indicating that the internet was their primary source of information. Among those with an SCI who were unaware of AD, most (34/35 = 97.1%) wanted to learn about AD. The self-assessed quality of life was insignificantly better in patients with an SCI below T6 than in those with higher lesions. Patients with AD reported different symptoms and the most frequently reported symptom was a headache (70%). In 64% of participants, the primary trigger of AD were issues with the urinary bladder. In most individuals (55%), symptoms were not recognized by the healthcare providers. The individuals with AD were dissatisfied with the information about AD they received from doctors or nurses. Overall, 61% of all participants with AD rated their quality of life as good. Conclusions: Persons with an SCI are not adequately informed about AD. In most persons with AD, their symptoms are not properly recognized by healthcare providers. Our results suggest the need for more education of healthcare professionals about AD. Full article

(1) Background: Spinal cord injury (SCI) represents a major health challenge, often leading to significant and permanent sensorimotor and autonomic dysfunctions. This study reviews the evolving role of epidural spinal cord stimulation (eSCS) in treating chronic SCI, focusing on its efficacy and safety. The objective was to analyze how eSCS contributes to the recovery of neurological functions in SCI patients. (2) Methods: We utilized the PRISMA guidelines and performed a comprehensive search across MEDLINE/PubMed, Embase, Web of Science, and IEEE Xplore databases up until September 2023. We identified studies relevant to eSCS in SCI and extracted assessments of locomotor, cardiovascular, pulmonary, and genitourinary functions. (3) Results: A total of 64 studies encompassing 306 patients were identified. Studies investigated various stimulation devices, parameters, and rehabilitation methods. Results indicated significant improvements in motor function: 44% of patients achieved assisted or independent stepping or standing; 87% showed enhanced muscle activity; 65% experienced faster walking speeds; and 80% improved in overground walking. Additionally, eSCS led to better autonomic function, evidenced by improvements in bladder and sexual functions, airway pressures, and bowel movements. Notable adverse effects included device migration, infections, and post-implant autonomic dysreflexia, although these were infrequent. (4) Conclusion: Epidural spinal cord stimulation is emerging as an effective and generally safe treatment for chronic SCI, particularly when combined with intensive physical rehabilitation. Future research on standardized stimulation parameters and well-defined therapy regimens will optimize benefits for specific patient populations. Full article

Background: The prevention of lower extremity fractures and fracture-related morbidity and mortality is a critical component of health services for adults living with chronic spinal cord injury (SCI). Methods: Established best practices and guideline recommendations are articulated in recent international consensus documents from the International Society of Clinical Densitometry, the Paralyzed Veterans of America Consortium for Spinal Cord Medicine and the Orthopedic Trauma Association. Results: This review is a synthesis of the aforementioned consensus documents, which highlight the pathophysiology of lower extremity bone mineral density (BMD) decline after acute SCI. The role and actions treating clinicians should take to screen, diagnose and initiate the appropriate treatment of established low bone mass/osteoporosis of the hip, distal femur or proximal tibia regions associated with moderate or high fracture risk or diagnose and manage a lower extremity fracture among adults with chronic SCI are articulated. Guidance regarding the prescription of dietary calcium, vitamin D supplements, rehabilitation interventions (passive standing, functional electrical stimulation (FES) or neuromuscular electrical stimulation (NMES)) to modify bone mass and/or anti-resorptive drug therapy (Alendronate, Denosumab, or Zoledronic Acid) is provided. In the event of lower extremity fracture, the need for timely orthopedic consultation for fracture diagnosis and interprofessional care following definitive fracture management to prevent health complications (venous thromboembolism, pressure injury, and autonomic dysreflexia) and rehabilitation interventions to return the individual to his/her pre-fracture functional abilities is emphasized. Conclusions: Interprofessional care teams should use recent consensus publications to drive sustained practice change to mitigate fracture incidence and fracture-related morbidity and mortality among adults with chronic SCI.

Spinal cord injury (SCI) produces damage to the somatic and autonomic pathways that regulate lower urinary tract, sexual, and bowel function, and increases the risk of autonomic dysreflexia. The recovery of these functions has a high impact on health, functioning, and quality of life and is set as the utmost priority by patients. The application of reliable models to predict lower urinary tract, sexual, and bowel function, and autonomic dysreflexia is important for guiding counseling, rehabilitation, and social reintegration. Moreover, a reliable prediction is essential for designing future clinical trials to optimize patients’ allocation to different treatment groups. To date, reliable and simple algorithms are available to predict lower urinary tract and bowel outcomes after traumatic and ischemic SCI. Previous studies identified a few risk factors to develop autonomic dysreflexia, albeit a model for prediction still lacks. On the other hand, there is an urgent need for a model to predict the evolution of sexual function. The aim of this review is to examine the available knowledge and models for the prediction of lower urinary tract, sexual, and bowel function, and autonomic dysreflexia after SCI, and critically discuss the research priorities in these fields.

Spinal cord injury (SCI) results in severe cardiovascular dysfunction due to the disruption of supraspinal control. Autonomic dysreflexia (AD), an uncontrolled rise in blood pressure in response to peripheral stimuli including common bowel routine, digital anorectal stimulation (DARS), reduces the quality of life, and increases morbidity and mortality. Recently, spinal cord stimulation (SCS) has emerged as a potential intervention to mitigate unstable blood pressure following SCI. The objective of this case series was to test the real-time effect of epidural SCS (eSCS) at the lumbosacral spinal cord, the most common implant location, on mitigating AD in individuals with SCI. We recruited three individuals with cervical and upper thoracic motor-complete SCI who have an implanted epidural stimulator. We demonstrated that eSCS can reduce the elevation in blood pressure and prevent DARS-induced AD. The blood pressure variability analysis indicated that eSCS potentially reduced vascular sympathetic nervous system activity during DARS, compared to without eSCS. This case series provides evidence to support the use of eSCS to prevent AD episodes during routine bowel procedures, improving the quality of life for individuals with SCI and potentially reducing cardiovascular risks.

Spinal cord injuries (SCI) have a profound impact on autonomic systems, sometimes resulting in multi-organ dysfunction, including of the neurogenic bladder. Autonomic dysreflexia (AD) is commonly seen in patients with SCI above T6 when the injured cord develops a deregulated sympathetic reflex, which can be induced by bladder sensation and can cause hypertensive crisis. While intravesical injection of botulinum toxin A (Botox) is a standard therapy for neurogenic detrusor overactivity, the role of Botox for AD has rarely been described. This study reviewed the medical records of SCI patients who reported AD and received either detrusor or urethral sphincter injection with Botox. The primary endpoint is the subjective improvement of AD. The secondary endpoint is a change in videourodynamic parameters before and after Botox injection. A total of 200 patients were enrolled for analysis. There were 125 (62.5%) patients in the detrusor injection group, and 75 (37.5%) in the urethral sphincter injection group. There were 79 (63.2%) patients in the detrusor injection group and 43 (57.3%) in the urethral sphincter injection group reporting moderate or marked improvement. Detrusor injection leads to a greater improvement in AD, probably because of decreased detrusor pressure and increased compliance after Botox injection. Urethral sphincter injection appears to have a modest effect on AD, despite general improvements in the voiding parameters of videourodynamic study. Full article

Spinal cord injury (SCI) is a debilitating condition that can significantly affect an individual’s life, causing paralysis, autonomic dysreflexia, and chronic pain. Transspinal stimulation (TSS) is a non-invasive form of neuromodulation that activates the underlying neural circuitries of the spinal cord. Application of TSS can be performed through multiple stimulation protocols, which may vary in the electrodes’ size or position as well as stimulation parameters, and which may influence the response of motor functions to the stimulation. Due to the novelty of TSS, it is beneficial to summarize the available evidence to identify the range of parameters that may provide the best outcomes for motor response. The PubMed and Google Scholar databases were searched for studies examining the effects of TSS on limb motor function. A literature search yielded 34 studies for analysis, in which electrode placement and stimulation parameters varied considerably. The stimulation protocols from each study and their impact on limb motor function were summarized. Electrode placement was variable based on the targeted limb. Studies for the upper limbs targeted the cervical enlargement with anatomical placement of the cathode over the cervical vertebral region. In lower-limb studies, the cathode(s) were placed over the thoracic and lumbar vertebral regions, to target the lumbar enlargement. The effects of carrier frequency were inconclusive across the studies. Multisite cathodal placements yielded favorable motor response results compared to single-site placement. This review briefly summarized the current mechanistic evidence of the effect of TSS on motor response after SCI. Our findings indicate that optimization of stimulation parameters will require future randomized controlled studies to independently assess the effects of different stimulation parameters under controlled circumstances.

Spinal cord injury can either be complete with no neural communication across the injury level or incomplete with limited communication. Similarly, motor neuron injuries above the sacral spinal cord are classified as upper motor neuron injuries, while those inside the sacral cord are classified as lower motor neuron injuries. Specifically, we provide recommendations regarding the urological management of complete upper motor neuron spinal cord injuries; however, we also make limited comments related to other injuries. The individual with a complete upper motor neuron injury may encounter five lower urinary tract conditions: first, neurogenic detrusor overactivity causing urinary incontinence; second, neurogenic detrusor underactivity resulting in high post-void residual volumes; third, detrusor sphincter dyssynergia, which is contraction of striated and/or smooth muscle urethral sphincters during detrusor contractions; fourth, urinary tract infection; and fifth, autonomic dysreflexia during detrusor contractions, which produces high blood pressure as well as smooth muscle detrusor sphincter dyssynergia. Intermittent catheterization is the recommended urinary management method because it addresses the five lower urinary tract conditions and has good long-term outcomes. This method uses periodic catheterizations to drain the bladder, but also needs bladder inhibitory interventions to prevent urinary incontinence between catheterizations. Primary limitations associated with this management method include difficulties with the multiple catheterizations, side effects of bladder inhibitory medications, and urinary tract infections. Three suggestions to address these concerns include the use of low-friction catheters, wireless, genital-nerve neuromodulation for bladder inhibition, and consideration of urine egress into the urethra as a risk factor for UTI as well as egress treatment. The second management method is reflex voiding. This program uses external condoms for urine collection in males and diapers for females. Suprapubic tapping is used to promote bladder contractions. This method is not recommended because it has high rates of medical complications. In particular, it is associated with high detrusor pressure, which can lead to ureteral reflux and kidney pathology. Botulinum toxin injection into the urethral striated sphincter can manage detrusor sphincter dyssynergia, reduce voiding pressures, and risks to the kidney. We suggest a modified method for botulinum toxin injections as well as five additional methods to improve reflex voiding outcomes. Finally, the use of intermittent catheterization and reflex voiding for individuals with incomplete spinal injuries, lower motor neuron injuries and multiple scleroses are briefly discussed.

Botulinum toxin A (Botox) had been considered a promising drug that has an effect on functional disorders of the lower urinary tract. Because Botox exhibits anti-inflammatory and antispasmodic effects, Botox injection into the bladder can decrease detrusor contractility, reduce bladder hypersensitivity, and eliminate painful sensations. Injecting Botox into the bladder outlet can relax the hyperactivity of the bladder neck, and of the urethral smooth and striated muscles. Based on these therapeutic effects, Botox has been widely applied to treat lower-urinary-tract dysfunctions (LUTDs) such as overactive bladder and neurogenic detrusor overactivity. However, this treatment has not been licensed for use in other LUTDs such as interstitial cystitis, voiding dysfunction due to benign prostatic hyperplasia in men, and dysfunctional voiding in women. Botox has also not been approved for the treatment of children with overactive bladder and dysfunctional voiding; in patients with spinal cord injuries with detrusor sphincter dyssynergia and autonomic dysreflexia; or for poorly relaxed external sphincter in non-neurogenic patients. This article reviews the current knowledge regarding Botox treatment for LUTDs and discusses the potential clinical applications of Botox, as well as work that can be conducted in the future.

The autonomic nervous system (ANS), composed of the sympathetic and parasympathetic nervous systems, acts to maintain homeostasis in the body through autonomic influences on the smooth muscle, cardiac muscles, blood vessels, glands and organs of the body. The parasympathetic nervous system interacts via the cranial and sacral segments of the central nervous system, and the sympathetic nervous system arises from the T1–L2 spinal cord segments. After a spinal cord injury (SCI), supraspinal influence on the ANS is disrupted, leading to sympathetic blunting and parasympathetic dominance resulting in cardiac dysrhythmias, systemic hypotension, bronchoconstriction, copious respiratory secretions and uncontrolled bowel, bladder, and sexual dysfunction. Further, afferent signals to the sympathetic cord elicit unabated reflex sympathetic outflow in response to noxious stimuli below the level of SCI. This article outlines the pathophysiology of SCI on the ANS, clinical ramifications of autonomic dysfunction, and the potential long-term sequelae of these influences following SCI. Full article

Pediatric spina bifida (SB) and spinal cord injury (SCI) are unfortunately common in our society, and their unique findings and comorbidities warrant special consideration. This manuscript will discuss the epidemiology, pathophysiology, prevention, and management strategies for children growing and developing with these unique neuromuscular disorders. Growth and development of the maturing child places them at high risk of spinal cord tethering, syringomyelia, ascending paralysis, pressure injuries, and orthopedic abnormalities that must be addressed frequently and judiciously. Similarly, proper neurogenic bladder and neurogenic bowel management is essential not just for medical safety, but also for optimal psychosocial integration into the child’s expanding social circle.

Urinary incontinence is common after spinal cord injury (SCI) due to loss of supraspinal coordination and unabated reflexes in both autonomic and somatic nervous systems; if unchecked, these disturbances can become life-threatening. This manuscript will review normal anatomy and physiology of the urinary system and discuss pathophysiology secondary to SCI. This includes a discussion of autonomic dysreflexia, as well as its diagnosis and management. The kidneys and the ureters, representing the upper urinary tract system, can be at risk related to dyssynergy between the urethral sphincters and high pressures that lead to potential vesicoureteral reflux, urinary tract infections, and calculi associated with neurogenic lower urinary tract dysfunction (NLUTD). Recent guidelines for diagnosis, evaluation, treatment and follow up of the neurogenic bladder will be reviewed and options provided for risk stratification and management. Mechanical, pharmacological, neurolysis and surgical management will be discussed. Full article

Detrusor sphincter dyssynergia (DSD) is defined as an external urethral sphincter anomalous contraction concomitant to detrusor contraction during voiding, due to a neurological disease. It commonly occurs in suprasacral spinal cord-injured (SCI) patients and can be associated with autonomic dysreflexia. DSD generates risks to the urinary system and overall health; hence, it should be promptly diagnosed and managed. Bladder neck dyssynergia is a condition that should be integrated in DSD assessment. We reviewed the literature indexed in PubMed/Medline on the evaluation methods of DSD in SCI patients. Urodynamics is the mainstay evaluation method and has a prognostic value for the progression of upper urinary tract structural degradation and renal function decline. We found a lack of consensus on the optimal urodynamics configuration when evaluating DSD, especially in obtaining and measuring the signal from external urethral sphincter (EUS) activity. It appears that a combination of recordings of voiding cystourethrography and EUS electromyography, either with or without EUS pressure measurement, is the most accurate method available for evaluating DSD. While gathering articles, we came across an interesting approach in evaluating DSD in the past: urodynamics coupled with ultrasound imaging. Despite being considered valuable from a diagnostic standpoint by some prominent authors, it is no longer represented in the current literature. In addition to the instrumental diagnosis, health professionals should consider additional clinical features when evaluating and managing DSD in SCI patients, to design a customized plan to achieve the best compromise between quality of life and urinary system protection.
