STUDY DESIGN: Bibliometric analysis. OBJECTIVES: An analysis of the literature related to the assessment and management of spinal trauma was undertaken to allow the identification of top contributors, collaborations and research trends. METHODS: A search to identify original articles published in English between 2011 and 2020 was done using specific keywords in the Web of Science database. After screening, the top 300 most cited articles were analyzed using Biblioshiny R software. RESULTS: The highest number of contributions were from the Thomas Jefferson University, USA, University of Toronto and University of British Columbia, Canada. The top 3 most prolific authors were Vaccaro AR, Arabi B, and Oner FC. The USA and Canada were among the top contributing countries; Switzerland and Brazil had most multiple country co-authored articles. The most relevant journals were the European Spine Journal, Spine and Spine Journal. Three of the 5 most cited articles were about classification systems of fractures. The keyword analysis included clusters for different spinal regions, spinal cord injury, classification agreement and reliability studies, imaging related studies, surgical techniques and outcomes. CONCLUSIONS: The study identified the most impactful authors and affiliations, and determined the journals where most impactful research is published in the field. Study also compared the productivity and collaborations across countries. The study highlighted the impact of development of new classification systems, and identified research trends including instrumentation, fixation and decompression techniques, epidemiology and recovery after spinal trauma.

Recovery of function following a complete spinal cord injury (SCI) or an incomplete SCI where recovery has plateaued still eludes us despite extensive research. Epidural spinal cord stimulation (SCS) was initially used for managing neuropathic pain. It has subsequently demonstrated improvement in motor function in otherwise non-recovering chronic spinal cord injury in animal and human trials. The mechanisms of how it is precisely effective in doing so will need further research, which would help refine the technology for broader application. Transcutaneous spinal cord stimulation (TSCS) is also emerging as a modality to improve the functional outcome in SCI individuals, especially when coupled with appropriate rehabilitation. Apart from motor recovery, ESCS and TSCS have also shown improvement in autonomic, metabolic, genitourinary, and pulmonary function. Since the literature on this is still in its infancy, with no large-scale randomised trials and different studies using different protocols in a wide range of patients, a review of the present literature is imperative to better understand the latest developments in this field. This article examines the existing literature on the use of SCS for SCI individuals with the purpose of enabling functional recovery. It also examines the voids in the present research, thus providing future directions.

Background: The key rehabilitation goal for cervical cord injury is promoting functional hand movement. Patients with mid to low-level cervical spinal cord injury can achieve the useful tenodesis grasp with the assistance of upper extremity orthosis. In this study, a custom molded writing device was fabricated and applied on cervical cord injured patients with the aim of hand rehabilitation. Methods: A total of fourteen individuals with cervical spinal cord injury at C6-C7 level were recruited for the study. They were divided into two groups, where the experimental group was prescribed with the custom molded writing device and the standard-of-care group was prescribed with the traditionally available writing device. The performance of the devices was evaluated using the Quest 2.0 questionnaire and the quality of writing after an intervention time of 4 weeks. Result: The group that used custom molded writing device performed comparatively better when compared to the conventional design. The data showed a significant difference with average QUEST scores of 4.47 ± 0.33 for the group using the wrist-driven writing device and 3.04 ± 0.70 for group using the conventional design. For better understanding of the device's performance, the writing with both the splints was also assessed. Conclusion: A writing device using the tenodesis grasp was fabricated to rehabilitate the writing skills of individuals with cervical spinal cord injuries. The performance of the device provided a favorable result indicating to elaborate the study for future references.

INTRODUCTION: Achondroplasia is a rare autosomal dominant condition characterized by stenosis in spinal canal. Multilevel Ossification of the ligamentum flavum in the spine is a rare occurrence which too can contribute to stenosed canal. CASE PRESENTATION: We report a case of an Indian achondroplasic dwarf with multilevel ossification of ligamentum flavum (OLF) at thoracic and lumbar segment. She presented in the outpatient department with bilateral weakness in legs with complete foot drop on the left side and was non-ambulatory. She was managed surgically by instrumentation with multiple interbody fusions with wide decompression and excision of OLF. The patient responded well to the surgery and became a walker after 2-year follow-up. DISCUSSION: Achondroplasic patients may present rarely with multiregional and multilevel OLF. It is important to identify them preoperatively so as to have good surgical outcome. Wide laminectomy, removal of the ossified ligament, and fusion with instrumentation resulted in the improvement of the patient's neurological symptoms and functions.

Sacropelvic is a complex junctional area owing to the complex regional anatomy and higher biomechanical stress. However extension of construct is indicated in cases with complex deformities, high grade spondylolisthesis, and complex fractures. The challenges remain which includes pseudoarthrosis and fixation failures. The fixation techniques have constantly evolved over time with better results with iliac screws and S2-alar-iliac screws. This article gives background on evolution, biomechanics, and recent update of use of robotics for sacropelvic fixation.

BACKGROUND: Spinal hematomas are rarely associated with dengue syndrome and usually occur at the time of active dengue fever. Late presentation after recovery from dengue fever, intradural hematoma, presentation as a multiloculated cystic lesion with longitudinal extensive myelitis, and recurrence after surgery are rarely or not described. Due to the peculiar association of all these findings, we report this case to provide insight into the existence of such a rare presentation. CASE DESCRIPTION: A 79-year-old-male developed sudden-onset paraparesis after 1 week of recovery from dengue fever. The blood counts were normal. Magnetic resonance imaging of the thoracic spine was suggestive of intradural hematoma. The patient underwent emergency decompression and drainage of hematoma with recovery in the neurologic status over the next few weeks. He presented to our emergency department after 5 weeks of the first surgery with deterioration in the neurologic status to complete paraplegia. Repeat magnetic resonance imaging showed a posterior epidural collection bulging anteriorly, causing cord compression. The patient was reoperated on by decompression. There was no neurologic recovery. The patient was managed with multidisciplinary rehabilitation, and he was independent in most of the activities at the time of discharge. CONCLUSIONS: Spinal hematoma should be kept in mind in patients who present with neurologic complications after dengue fever. It can have an atypical radiologic presentation and may present with recurrent hemorrhage after surgery. Attention should also be given to delayed presentation of neurologic complications, which may develop even after weeks of recovery from dengue fever.

BACKGROUND: Complications such as anterior knee pain (AKP) and crepitus continue to be causes of dissatisfaction after total knee arthroplasty (TKA). This prospective study aimed to study the significance of total patellar contact with the femoral trochlea of the implant, with the no thumb test during trial reduction, and its effect on reducing AKP. METHODS: Between 2014 and 2016, 445 patellofemoral joints (M:F 126:319, age 45-80 years) and their contact with the trochlea of the femoral component were graded at trial reduction without lateral retinaculum release (Grades I, Ia, II, III based on existing publications). The aim was to restore all patellae to pre-operative thickness. Posterior stabilized implants with a domed patella were used in all cases. The Knee Society Score (KSS) and Visual Analogue Scale (VAS) score were noted at follow up between 12 and 24 months after surgery. RESULTS: AKP was significantly lower with 100% patellofemoral contact. The KSS and VAS had statistically significant P-values of 0.021 and 0.025 in Grade I and Ia contact, respectively. Better results were achieved where patellar thickness was restored in Grades I and Ia with P-values of 0.041 and 0.046 for VAS change and 0.038 and 0.044 for KSS change, respectively. CONCLUSION: At follow up, superior results were obtained where there was a complete patellofemoral contact at trial reduction in Grade I and Grade Ia, and when other confounding factors such as patellar thickness and normal rotation of the femoral and tibial components were standardized. To minimize AKP it is imperative to have total patellar contact with the femoral trochlea.

INTRODUCTION: Paragangliomas are relatively rare tumors, accounting for only about 0.3% of all neoplasms. Most paragangliomas are defined as benign in nature, but 10-% possess metastatic potential. There have been scattered reports of metastatic paraganglioma in the literature, but in rare circumstances, paragangliomas can metastasize to the spinal column causing destruction or compression of the spinal cord, clinically manifesting as pain or neurological deficit. CASE REPORT: We present a case of a 43-year-old man who presented with paresthesia and paraparesis and was found to have pathologic fracture involving D1 vertebra as a manifestation of metastasis from a non-secretory right paratesticular paraganglioma. CONCLUSIONS: We will review the literature on the topic of metastatic paraganglioma, management of paragangliomas involving spine, and touch on the importance of angioembolization, staged procedures, and a team approach.

AIM: To study the functional and radiological outcomes in cases managed conservatively for single-level traumatic thoracolumbar spine fractures without neurological deficit. MATERIALS AND METHODS: In this prospective study design, thirty patients who presented to tertiary care hospital and diagnosed with posttraumatic thoracolumbar vertebral fracture without any neurodeficit were recruited. All the patients were managed conservatively as per the protocol which included bed rest, spinal braces, and physiotherapy. Adequate analgesia was given wherever necessary. The patients were followed at regular intervals up to a maximum of 2 years. Clinically visual analog scale (VAS) score and Roland Morris Disability Questionnaire (RMDQ)-24 were assessed and radiologically local vertebral kyphosis, scoliosis, and loss of body height were noted at each follow-up. RESULTS: The data was statistically analyzed and the results were as follows. Thoracolumbar fractures were more in young adults (<26 years) and more so among the males (80% cases). The most common fracture type in our study was compression fracture. The most common site involved in our study was L1 vertebra (36.7%). There was a significant decrease of VAS score (pain score) in 79% cases with the maximum decrease in type A1 fracture. The mean RMDQ-4 score in our study was 5.53. The overall progression of kyphosis was 1.9°. There was no relation found between the kyphotic deformity and the clinical outcomes (VAS and RMDQ-24 scores). Canal size changes were found to be insignificant at the end of 2 years compared to baseline. CONCLUSION: Study showed favorable outcomes in terms of return to daily activities, making it a good option in managing Type A1 dorsolumbar fractures. Though there was a progression of kyphosis but no neurological deficit was seen.
