Timing of intervention for spinal injury in patients with polytrauma

Early major fracture care in polytrauma-priorities in the context of concomitant injuries: A Delphi consensus process and systematic review

BACKGROUND

The timing of major fracture care in polytrauma patients has a relevant impact on outcomes. Yet, standardized treatment strategies with respect to concomitant injuries are rare. This study aims to provide expert recommendations regarding the timing of major fracture care in the presence of concomitant injuries to the brain, thorax, abdomen, spine/spinal cord, and vasculature, as well as multiple fractures.

METHODS

This study used the Delphi method supported by a systematic review. The review was conducted in the Medline and EMBASE databases to identify relevant literature on the timing of fracture care for patients with the aforementioned injury patterns. Then, consensus statements were developed by 17 international multidisciplinary experts based on the available evidence. The statements underwent repeated adjustments in online- and in-person meetings and were finally voted on. An agreement of ≥75% was set as the threshold for consensus. The level of evidence of the identified publications was rated using the GRADE approach.

RESULTS

A total of 12,476 publications were identified, and 73 were included. The majority of publications recommended early surgery (47/73). The threshold for early surgery was set within 24 hours in 45 publications. The expert panel developed 20 consensus statements and consensus >90% was achieved for all, with 15 reaching 100%. These statements define conditions and exceptions for early definitive fracture care in the presence of traumatic brain injury (n = 5), abdominal trauma (n = 4), thoracic trauma (n = 3), multiple extremity fractures (n = 3), spinal (cord) injuries (n = 3), and vascular injuries (n = 2).

CONCLUSION

A total of 20 statements were developed on the timing of fracture fixation in patients with associated injuries. All statements agree that major fracture care should be initiated within 24 hours of admission and completed within that timeframe unless the clinical status or severe associated issues prevent the patient from going to the operating room.

A case of damage control after polytrauma and bilateral femur fracture

Introduction

Multi-trauma patients require a multidisciplinary team, especially in the presence of various body systems injuries. The evaluation focuses on the decision regarding the DCO and ETC approaches.

Case presentation

A 24-year-old male patient with Glasgow Coma Score 8, arrived at the emergency room, followed by ATLS protocol. Orthopedic trauma included D8 vertebra unstable burst fracture, right open femur shaft fracture, left closed midshaft femur fracture, and right tibial plateau fracture of the knee.

Case summary

A hemodynamically stable patient with bilateral femur fractures is directed toward the DCO approach.

Discussion

An initial treatment for an external fixator across the knee on the right leg and a spine fusion and decompression of D5-10 surgery was made on the day of admission. Definitive fixation and conversion to internal fixators were done on day 9 after the accident. Postoperative drop-foot injury was seen in the right leg. A Masquelet technique was applied for the right femur segmental fracture due to gaps.

Conclusion

DCO may be employed to temporarily stabilize fractures, allowing the patient to recover from other life-threatening injuries before definitive fixation. Further secondary procedures, such as the Masquelet technique, should be considered to optimize the results. Long-term follow-up and rehabilitation are part of recovery, aiming to optimize functional recovery and improve the patient's quality of life.

Traumatic thoracolumbar spondyloptosis of T12-L1 with stable hemodynamics: A case report

INTRODUCTION AND IMPORTANCE

A fracture-dislocation of the vertebral bone is mostly caused by high-energy trauma. Spondyloptosis is the severest form of spondylolisthesis (>100 %) which affects the sagital or coronal plane from the contiguous vertebral bone. Anterior spondyloptosis is known as fracture-dislocation where the proximal part of the vertebra is located infront of the distal vertebrae. Most cases are associated with spinal cord injury (SCI) and unstable hemodynamics, in this case the vital sign of the patient's tend to be stable.

CASE PRESENTATION

A 21-year-old man had multiple traumas after having a traffic injury, pain and numbness were positive during physical examination, especially in both lower limb. A radiography examination shows that the patient had total spinal cord transection and anterior spondyloptosis in T12 until L1 segment. Additional examinations found minimal renal and liver contusion including the ischemic bowel. The interbody fusion procedure was chosen as our therapeutic modalities.

CLINICAL DISCUSSION

We performed open surgical methods by using interbody fusion modalities usually in patient's with stable vital signs. This intervention could be the priority in managing patients with a rare case of anterior spondyloptosis. A visual analog Scale (VAS) was used for monitoring the degree of pain, and Oswestry Disability Index (ODI) questionnaire for evaluating the outcome for low back pain.

CONCLUSIONS

Most traumatic spondyloptosis cases end with neurogenic shock, Due to the injury's rarity and collaborated with minimal soft tissue injury, early diagnosis and the use of an open surgical method may improve patient's outcome.

Quality of in-hospital care in traumatic spinal column and cord injuries (TSC/SCI) in I.R Iran

PURPOSE

This study aimed to implement the Quality of Care (QoC) Assessment Tool from the National Spinal Cord/Column Injury Registry of Iran (NSCIR-IR) to map the current state of in-hospital QoC of individuals with Traumatic Spinal Column and Cord Injuries (TSCCI).

METHODS

The QoC Assessment Tool, developed from a scoping review of the literature, was implemented in NSCIR-IR. We collected the required data from two primary sources. Questions regarding health system structures and care processes were completed by the registrar nurse reviewing the hospital records. Questions regarding patient outcomes were gathered through patient interviews.

RESULTS

We registered 2812 patients with TSCCI over six years from eight referral hospitals in NSCIR-IR. The median length of stay in the general hospital and intensive care unit was four and five days, respectively. During hospitalization 4.2% of patients developed pressure ulcers, 83.5% of patients reported satisfactory pain control and none had symptomatic urinary tract infections. 100%, 80%, and 90% of SCI registration centers had 24/7 access to CT scans, MRI scans, and operating rooms, respectively. Only 18.8% of patients who needed surgery underwent a surgical operation in the first 24 h after admission. In-hospital mortality rate for patients with SCI was 19.3%.

CONCLUSION

Our study showed that the current in-hospital care of our patients with TSCCI is acceptable in terms of pain control, structure and length of stay and poor regarding in-hospital mortality rate and timeliness. We must continue to work on lowering rates of pressure sores, as well as delays in decompression surgery and fatalities.

Concomitant Traumatic Brain Injury Delays Surgery in Patients With Traumatic Spinal Cord Injury

BACKGROUND AND OBJECTIVES

Growing evidence supports prompt surgical decompression for patients with traumatic spinal cord injury (tSCI). Rates of concomitant tSCI and traumatic brain injury (TBI) range from 10% to 30%. Concomitant TBI may delay tSCI diagnosis and surgical intervention. Little is known about real-world management of this common injury constellation that carries significant clinical consequences. This study aimed to quantify the impact of concomitant TBI on surgical timing in a national cohort of patients with tSCI.

METHODS

Patient data were obtained from the National Trauma Data Bank (2007-2016). Patients admitted for tSCI and who received surgical intervention were included. Delayed surgical intervention was defined as surgery after 24 hours of admission. Multivariable hierarchical regression models were constructed to measure the risk-adjusted association between concomitant TBI and delayed surgical intervention. Secondary outcome included favorable discharge status.

RESULTS

We identified 14 964 patients with surgically managed tSCI across 377 North American trauma centers, of whom 2444 (16.3%) had concomitant TBI and 4610 (30.8%) had central cord syndrome (CCS). The median time to surgery was 20.0 hours for patients without concomitant TBI and 24.8 hours for patients with concomitant TBI. Hierarchical regression modeling revealed that concomitant TBI was independently associated with delayed surgery in patients with tSCI (odds ratio [OR], 1.3; 95% CI, 1.1-1.6). Although CCS was associated with delayed surgery (OR, 1.5; 95% CI, 1.4-1.7), we did not observe a significant interaction between concomitant TBI and CCS. In the subset of patients with concomitant tSCI and TBI, patients with severe TBI were significantly more likely to experience a surgical delay than patients with mild TBI (OR, 1.4; 95% CI, 1.0-1.9).

CONCLUSION

Concomitant TBI delays surgical management for patients with tSCI. This effect is largest for patients with tSCI with severe TBI. These findings should serve to increase awareness of concomitant TBI and tSCI and the likelihood that this may delay time-sensitive surgery.

Catalytic antioxidant nanoparticles mitigate secondary injury progression and promote functional recovery in spinal cord injury model

Traumatic spinal cord injury exacerbates disability with time due to secondary injury cascade triggered largely by overproduction of reactive oxygen species (ROS) at the lesion site, causing oxidative stress. This study explored nanoparticles containing antioxidant enzymes (antioxidant NPs) to neutralize excess ROS at the lesion site and its impact. When tested in a rat contusion model of spinal cord injury, a single dose of antioxidant NPs, administered intravenously three hours after injury, effectively restored the redox balance at the lesion site, interrupting the secondary injury progression. This led to reduced spinal cord tissue inflammation, apoptosis, cavitation, and inhibition of syringomyelia. Moreover, the treatment reduced scar tissue forming collagen at the lesion site, protected axons from demyelination, and stimulated lesion healing, with further analysis indicating the formation of immature neurons. The ultimate effect of the treatment was improved motor and sensory functions and rapid post-injury weight loss recovery. Histological analysis revealed activated microglia in the spinal cord displaying rod-shaped anti-inflammatory and regenerative phenotype in treated animals, contrasting with amoeboid inflammatory and degenerative phenotype in untreated control. Overall data suggest that restoring redox balance at the lesion site shifts the dynamics in the injured spinal cord microenvironment from degenerative to regenerative, potentially by promoting endogenous repair mechanisms. Antioxidant NPs show promise to be developed as an early therapeutic intervention in stabilizing injured spinal cord for enhanced recovery.

A Comparison of Outcomes between the Wiltse Approach with Pedicle Screw Fixation and the Percutaneous Pedicle Screw Fixation for Multi-Segmental Thoracolumbar Fractures

OBJECTIVE

Multi-segmental thoracolumbar fracture (MSF) generally refers to fractures occurring in two or more segments of the thoracolumbar spine. With the development of minimally invasive concept, there is little research on its application in the field of MSF. The purpose of this study is to compare two minimally invasive surgical techniques and determine which one is more suitable for treating patients with neurologically intact MSF.

METHODS

We retrospectively analyzed the clinical data of 49 MSF patients with intact nerves who were admitted from January 2017 to February 2019. Among them, 25 cases underwent percutaneous pedicle screw fixation (PPSF), and 24 cases underwent Wiltse approach pedicle screw fixation (WAPSF). The operation time, number of fixed segments, blood loss, length of incision, postoperative ambulation time, accuracy of pedicle screw placement, facet joint violation (FJV), number of C-arm exposures, as well as pre- and postoperative visual analogue scale (VAS), Oswestry disability index (ODI), local Cobb's angle (LCA), and percentage of anterior vertebral body height (PAVBH) were recorded for both groups. Paired sample t-test was used for intra-group comparison before and after surgery while independent sample t-test was used for inter-group comparison.

RESULTS

The differences in the number of fixed segments, intraoperative bleeding, postoperative bed time, accuracy rate of pedicle screw placement, VAS, and ODI between the two groups were not statistically significant (p > 0.05). However, the operative time and total surgical incision length were significantly shorter in the WAPSF group than in the PPSF group (p < 0.05), and the FJV was significantly higher in the PPSF group than in the WAPSF group (p < 0.05). Also, the PPSF group received more intraoperative fluoroscopy (p < 0.05). The result of LCA and PAVBH in the WAPSF group were significantly better than in the PPSF group (p < 0.05).

CONCLUSIONS

Both PPSF and WAPSF were found to be safe and effective in the treatment of MSF without neurological deficits through our study. However, considering radiation exposure, FJV, vertebral height restoration, correction of kyphosis, and learning curve, WAPSF may be a better choice for neurologically intact MSF.
