Correlation of outcome measures with epidemiological factors in thoracolumbar spinal trauma

Pattern of spine fracture in Sub-Himalayan region: A prospective study

BACKGROUND

Though spine trauma contributes to great functional, psychological, and economic loss, research regarding the demographic profile of patients according to different regions of our country are lacking.This study aims to identify the demographic pattern and clinical profile of patients with spinal fracture in the Sub-Himalayan region.

METHOD

Patients with acute or subacute spine trauma presenting within 8weeks and involving fracture of cervical, dorsal, or lumbar vertebra, from July 2017 to December 2019 were included prospectively. Patients with osteoporotic or metastatic collapse, isolated transverse or spinous process fracture, penetrating trauma or ballistic injuries were excluded.

RESULTS

Out of 280 enrolled patients, 180 were males and 100 were females. The maximum number of spine trauma patients was in 16-30 years age group. The most common mechanism of injury was fall from height (FFH, 42.5%)> road traffic accident (RTA, 38.6%). RTA was more common among males and FFH among females (p < 0.0001). Most common location of injury was at thoracolumbar junction (D10-L2) (37.5%) followed by cervical spine (25.3%). 58.2% of patients had AO type A facture morphology followed by AO types C (36.1%) and AO type B (5.7%). Spinal Cord Injury (SCI) was seen in 82.1% spine trauma patients with statistically significant association with male gender (p- 0.045). Complete paralysis was seen maximum in patients with cervical spine injury (67.3%, p < 0.0001). Complete neurological deficit (ASIA grade A) was seen maximum in AO type C fracture morphology (74.25%, p < 0.001) followed by AO type A4 (29.6%). Seasonal distribution showed increased incidence during summer and monsoon season.

CONCLUSION

Young aged males in age group of 16-30 yrs were most commonly affected with fall from height as the most common mechanism of trauma. Association was found between gender and mechanism of injury (RTA in males and FFH in females). Most common vertebral injury level was thoracolumbar junction. AO type A was the most common fracture morphology. SCI seen in 82.1% of spine trauma. Statistically significant association was found between Complete SCI with Location of Injury (Cervical) and Fracture morphology (AO type C).

Surgery for Spinal Trauma: Early Days at a Young Institution in a Hilly State

Background Spinal trauma is associated with significant morbidity and affects the overall quality of life of the patient as well as their family. The aim of this study was to study the epidemiology, in-hospital outcome, and follow-up of patients undergoing surgery for spinal trauma.

Methods All patients who underwent surgery for spinal trauma at the Department of Neurosurgery between June 2016 and October 2019 were studied retrospectively. Data collected from patient record included demographic profile, mode of injury, level of injury, neurological status at admission, time from injury to operative intervention, hospital stay, neurological outcome at discharge, and follow-up. Postoperative computed tomography scans were done in all patients to check for adequacy of screw placement.

Results A total of 70 patients (45 males, 25 females) with a mean age of 36 years (range: 16–65 years) were operated for spinal injuries at our department during the study period. Fall was the most common mode of injury (77.1%), followed by road traffic accident (28.5%). Most common site of injury was lumbar spine (38.6%), followed by dorsal (32.9%) and cervical (28.5%). Out of the total, 27.1% of our patients were American Spinal Injury Association (ASIA) grade A at presentation whereas 18.6% were ASIA E. Remaining 54.3% patients had incomplete injuries (ASIA B, C, and D). Burst fracture was the most common morphology of injury (60%), followed by translational injuries (30%). Mean duration between injury and operative intervention was 20.8 days. The mean duration of hospital stay was 21.4 days (range: 8–90 days). Six patients expired during hospitalization. All these six cases had cervical spinal injury. One patient of dorsal spine injury with a complete neurological injury expired 6 months after discharge from the hospital (cause unknown). Nine of our cases showed neurological improvement on follow-up and in rest of the patients, neurological status remained same as preoperative status.

Conclusion Neurological status at admission (ASIA grade) and level of injury remain the most important predictor of the outcome. Spinal injury patients must be managed with a holistic and multidisciplinary approach. Rehabilitation is important for helping these patients in leading a productive life.

Role of minimally invasive percutaneous fixation in thoracolumbar fractures: a prospective study

Background

Each year, there are approximately 5 million new vertebral fractures worldwide. Being a mobile flexible segment that is prone to severe stresses and loads, thoracolumbar fractures are considered one of the most controversial and challenging fracture types to manage.

Objective

The aim of this study is to explore the technique and to evaluate feasibility, safety, and outcome of percutaneous transpedicular fixation in the management of thoracolumbar fractures.

Methods

This study was carried out in the period between May 2016 and June 2017, where 20 consecutive patients with thoracolumbar fractures, based on TLICS scoring and neurological status, underwent a posterior percutaneous transpedicular fixation. The mean age was 33.85 years, range 20–49 years. Patients were followed up for 12 months. Patients had their clinical outcomes reviewed and evaluated in terms of cosmesis by visual analog scale (VAS) and in terms of Cobb angle correction.

Results

The length of the procedure varied from 120 to 180 min with mean time of 154.50 min. There was no significant blood loss in all cases. The volume of blood loss ranged from 150 to 200 cc with mean loss of 174.25 cc.

No major intraoperative complications happened in our study cases. Six cases had only one laterally malpositioned screw each. All cases returned to their previous activity without limitations (E5). Those who were completely pain free (F5) were 15 patients. Only five patients were suffering from moderate pain (F4). The Prolo scale was either 9 or 10 with mean of 9.60.

Conclusion

By comparing our results with other studies, we found more or less equivalence in terms of neurological recovery, functional outcome, fusion rate, and maintenance of correction gain. However, the cosmesis scores for patients in the study were great.

Bystander Assistance for Trauma Victims in Low- and Middle-Income Countries: A Systematic Review of Prevalence and Training Interventions

OBJECTIVE

Lack of organized prehospital care may contribute to the disproportionate burden of trauma-related deaths in low- and middle-income countries (LMICs). The World Health Organization (WHO) recommends bystander training in basic principles of first aid and victim transport; however, prevalence of bystander or layperson assistance to trauma victims in LMICs has not been well-described, and organized reviews of existing evidence for bystander training are lacking. This systematic review aims to 1) describe the prevalence of bystander or layperson aid or transport for trauma victims in the prehospital setting in LMICs and 2) ascertain impacts of bystander training interventions in these settings.

METHODS

A systematic search of OVID Medline, Cochrane Library, and relevant gray literature was conducted. We included 1) all studies detailing prevalence of bystander-administered aid or transport for trauma victims in LMICs and 2) all randomized controlled trials and observational studies evaluating bystander training interventions. We extracted study characteristics, interventions, and outcomes data. Study quality was assessed using Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria.

RESULTS

Sixty-two studies detailed prevalence of bystander transport and aid. Family members, police, and bus or taxi drivers commonly transported patients; a majority of patients, up to >94%, received aid from bystanders. Twenty-four studies examined impacts of training interventions. Only one study looked at transport interventions; the remainder addressed first aid training. Interventions varied in content, duration, and target learners. Evidence was generally of low quality, but all studies demonstrated improvements in layperson knowledge and skills. Five studies reported a mortality reduction.

CONCLUSIONS

Heterogeneity in data reporting and outcomes limited formal meta-analysis. However, this review shows high rates of bystander involvement in prehospital trauma care and transport in LMICs and highlights the need for bystander training. Bystander training in these settings is feasible and may have an important impact on meaningful outcomes such as mortality. Categories of involved bystanders varied by region and training interventions should be targeted at relevant groups. "Train the trainer" models appear promising in securing community engagement and maximizing participation. Further research is needed to examine the value of bystander transport networks in trauma.

Occupant and Crash Characteristics of Elderly Subjects With Thoracic and Lumbar Spine Injuries After Motor Vehicle Collisions

STUDY DESIGN

Retrospective study of a prospectively gathered database.

OBJECTIVE

To investigate the incidence and pattern of thoracic and lumbar (T and L) spine injuries among elderly subjects involved in motor vehicle collision (MVC).

SUMMARY OF BACKGROUND DATA

Adults age 65 and older currently constitute more than 16% of all licensed drivers. Despite driving less than the young, older drivers are involved in a higher proportion of crashes. Notwithstanding the safety features in modern vehicles, 15.8% to 51% of all T and L spine injuries result from MVCs.

METHODS

Crash Injury Research and Engineering Network database is a prospectively maintained, multicentered database that enrolls MVC occupants with moderate-to-severe injuries. It was queried for T and L spine injuries in subjects 65 and older. 142 Crash Injury Research and Engineering Network files for all elderly individuals were reviewed for demographic, injury, and crash data. Each occupant's T and L injury was categorized using a modified Denis classification.

RESULTS

Of 661 elderly subjects, 142 (21.48%) sustained T and L spine injuries. Of the 102 major injuries, there were 63 compression, 20 burst and 12 extension fractures. Seatbelt use predisposed elderly subjects to compression and burst fractures, whereas seatbelt and airbag use predisposed to burst fractures. Deployment of airbags without seatbelt use appeared to predispose elderly subjects to neurological injury, higher Injury Severity Score, and higher mortality. Occupants using 3-point belts who had airbags deployed during the collision had the lowest rates of fatality and neurological injury.

CONCLUSION

T and L spine injuries in the elderly are not uncommon despite restraint use. Whereas seatbelts used alone and in conjunction with airbag deployment reduced fatalities and neurological injuries in the elderly, deployment of airbags in occupants without seatbelts predisposed to more severe injury.

Where do I go? A trauma victim's plea in an informal trauma system

BACKGROUND

The three pillars of a good trauma system are the prehospital care, definitive care, and rehabilitative services. The prehospital care is a critical component of the efforts to lower trauma mortality.

OBJECTIVE

To study the prehospital profile of patients who died due to trauma, compute the time taken to reach our facility, find the cause of delay, and make feasible recommendations.

MATERIALS AND METHODS

A hospital-based study was performed at a trauma center in Puducherry from June 2009 to August 2010. Puducherry is a union territory of India in the geographical terrain of the state of Tamil Nadu. A total of 241deaths due to trauma were included. Apart from the demographic and injury characteristics, a detailed prehospital log was constructed regarding the time of incident, the referral patterns, care given in the prehospital phase, the distance travelled, and the total time taken to reach our center.

RESULTS

The majority (59%) of patients were referred, with stopovers at two consecutive referral centers (30%), needing at least two vehicles to transport to definitive care (70%), clocking unnecessary distances (67%), and delayed due to non therapeutic intervention (87%). The majority of deaths (66%) were due to head injury. Only 2.96% of referred cases reached us within the first hour. Few of the patients coming directly to us had vehicle change due to local availability and lack of knowledge of predestined definitive care facility. Overall, 94.6% of direct cases arrived within 4 h whereas 93.3% of referred cases required up to 7 h to arrive at definitive care.

CONCLUSIONS

Seriously injured patients lose valuable prehospital time because there is no direction regarding destination and interfacility transfer, a lack of seamless transport, and no concept of initial trauma care. The lack of direction is compounded in geographical areas that are situated at the border of political jurisdictions.
