Early or delayed stabilization in severely injured patients with spinal fractures? Current surgical objectivity according to the Trauma Registry of DGU: treatment of spine injuries in polytrauma patients

Meta-analysis of early versus late fixation of traumatic unstable thoracolumbar spine fractures in patients with or without spinal cord injury

BACKGROUND AND OBJECTIVES

Timing of surgical fixation for unstable thoracolumbar Fractures in polytrauma patients remains controversial. We performed a meta-analysis to quantitatively evaluate the impact of early (< 72 h) versus late (> 72 h) thoracolumbar stabilization on in-hospital outcomes, including hospital and ICU length of stay, mortality, ventilator dependency, and complication rates.

METHODS

Studies comparing early and late surgical stabilization of traumatic thoracolumbar fractures were included. Outcomes analyzed included hospital length of stay (HLOS), ICU length of stay (ICULOS), days on a ventilator (VENTDAYS), complication rates, and in-hospital mortality. Complications included intraoperative hemorrhage, sepsis, postoperative neurological deterioration, and respiratory complications. Subset analysis was performed for non-SCI patients. Data were pooled using fixed or random-effects models based on heterogeneity.

RESULTS

Twelve studies met inclusion criteria. Early fixation was associated with shorter HLOS (mean difference [MD] = -3.59 days; 95 % confidence interval [CI]: -6.44 to -0.75, I2 = 31 %), shorter ICULOS (MD = -1.21 days; 95 % CI: -2.0 to -0.41, I2 = 0 %), and fewer VENTDAYS (MD = -3.43 days; 95 % CI: -6.07 to -0.78, I2 = 90 %). Early fixation also reduced the odds of perioperative complications (odds ratio [OR] = 0.61; 95 % CI: 0.49 to 0.75, I2 = 13 %) without increasing in-hospital mortality (OR = 1.04; 95 % CI: 0.73 to 1.46, I2 = 2 %). Subset analysis of non-SCI patients showed no differences in mortality (OR = 1.1; 95 % CI: 0.41 to 2.93, I2 = 0 %) or complication rates (OR = 0.79; 95 % CI: 0.36 to 1.73, I2 = 28 %).

CONCLUSION

Early fixation of traumatic thoracolumbar fractures is associated with decreased HLOS, ICULOS, complication rates, and ventilator dependency. Further prospective trials are required to confirm these findings and refine the role of SCI status in clinical decision-making for thoracolumbar fixation.

Comparison of the immobilizing effect of soft, semi-rigid and rigid neck orthoses

PURPOSE

Cervical orthoses are widely used in the management of cervical spine (c-spine) injuries, serving to limit motion, alleviate pain, and enhance patient security. While extensive research has examined soft and rigid cervical braces, data on semi-rigid braces, such as the PDC collar, remain scarce. This study aims to compare the immobilizing effects of a semi-rigid cervical orthosis to those of a soft and a rigid orthosis on c-spine mobility in healthy individuals.

METHODS

In a prospective study, 20 healthy participants (mean age 28.0 ± 6.0 years) underwent motion analysis using a 3D camera system under four conditions: without an orthosis and while wearing a soft, semi-rigid, and rigid orthosis. Maximum cervical range of motion (ROM) was measured during flexion/extension, lateral flexion, and axial rotation. The maximum active ROM was determined for each orthosis. After testing for normal distribution (Shapiro-Wilk test), repeated measures ANOVA with post-hoc Bonferroni-corrected t-tests was used for pairwise comparison of absolute ROM across orthoses.

RESULTS

All orthoses significantly restricted ROM compared to the unrestricted state (p < 0.01). Flexion/extension was the most restricted movement across all orthoses. The rigid orthosis provided the greatest restriction in all three movement directions, significantly reducing flexion/extension to 27.5° from an unrestricted ROM of 107.3° (p < 0.01). It also restricted rotation and lateral flexion significantly more than the semi-rigid and soft orthoses (p < 0.01). The semi-rigid orthosis significantly reduced flexion/extension compared to the soft collar (39.1° vs. 48.1°, p < 0.01), while no significant differences were observed between the two in rotation or lateral flexion.

CONCLUSION

The semi-rigid orthosis effectively limits c-spine mobility, particularly in flexion/extension, offering an intermediate option between soft and rigid braces. Its use may balance immobilization needs and patient comfort in cases requiring moderate motion restriction without increased complication risks.

[Current surgical treatment concepts for traumatic thoracic and lumbar vertebral fractures in adults with good bone quality]

The surgical treatment of traumatic vertebral body fractures in patients with good bone quality is controversially discussed. The data situation is unclear and only of limited help due to mainly insufficient evidence. The surgical measures include an axially aligned reduction and an osteosynthesis which is stable under load so that immediate mobilization of the patient is possible. This requires anatomical restoration of the alignment and the biomechanical challenge of fracture healing or fusion in the correct position without relevant loss of reduction must be taken into account. The aim should be the lowest possible loss of function. In the case of existing or impending neurological deficits it is crucial to prevent deterioration of the neurological situation and to achieve the prerequisites for recovery. Posterior stabilization primarily plays the decisive role in the operative treatment. If possible, this should be a minimally invasive procedure and over short distances. For bisegmental treatment monoaxial screws and the use of index screws improve construct stability. In addition, stable cobalt rods should be used as 5mm longitudinal support. Special minimally invasive reduction instruments are helpful in restoring the sagittal and coronal relationships. The indications for an additional ventral column depend on the rigidity of the posterior stabilization, the extent of the injury of the anterior column and the intervertebral disc. Anterior fusion can often be delayed or avoided altogether, depending on the course with corresponding clinical signs.

Timing of Spinal Surgery in Polytrauma: The Relevance of Injury Severity, Injury Level and Associated Injuries

STUDY DESIGN

Retrospective database analysis.

OBJECTIVE

Polytraumatized patients with spinal injuries require tailor-made treatment plans. Severity of both spinal and concomitant injuries determine timing of spinal surgery. Aim of this study was to evaluate the role of spinal injury localization, severity and concurrent injury patterns on timing of surgery and subsequent outcome.

METHODS

The TraumaRegister DGU® was utilized and patients, aged ≥16 years, with an Injury Severity Score (ISS) ≥16 and diagnosed with relevant spinal injuries (abbreviated injury scale, AIS ≥ 3) were selected. Concurrent spinal and non-spinal injuries were analysed and the relation between injury severity, concurrent injury patterns and timing of spinal surgery was determined.

RESULTS

12.596 patients with a mean age of 50.8 years were included. 7.2% of patients had relevant multisegmental spinal injuries. Furthermore, 50% of patients with spine injuries AIS ≥3 had a more severe non-spinal injury to another body part. ICU and hospital stay were superior in patients treated within 48 hrs for lumbar and thoracic spinal injuries. In cervical injuries early intervention (<48 hrs) was associated with increased mortality rates (9.7 vs 6.3%).

CONCLUSIONS

The current multicentre study demonstrates that polytrauma patients frequently sustain multiple spinal injuries, and those with an index spine injury may therefore benefit from standardized whole-spine imaging. Moreover, timing of surgical spinal surgery and outcome appear to depend on the severity of concomitant injuries and spinal injury localization. Future prospective studies are needed to identify trauma characteristics that are associated with improved outcome upon early or late spinal surgery.

Initial surgical management of spinal injuries in patients with multiple and/or severe injuries- the 2022 update of the German clinical practice guideline

PURPOSE

Our aim was to update evidence-based and consensus-based recommendations for the initial surgical management of spinal (cord) injuries in patients with multiple and/or severe injuries based on current evidence. This guideline topic is part of the 2022 update of the German Guideline on the Treatment of Patients with Multiple and/or Severe Injuries.

METHODS

MEDLINE and Embase were systematically searched to May 2021. Further literature reports were obtained from clinical experts. Randomised controlled trials, prospective cohort studies, and comparative registry studies were included if they compared interventions and the timing of interventions for the initial surgical management of spinal (cord) injuries in patients with polytrauma and/or severe injuries. We considered patient-relevant clinical outcomes such as mortality, complication rates, and lengths of stay. Risk of bias was assessed using NICE 2012 checklists. The evidence was synthesised narratively, and expert consensus was used to develop recommendations and determine their strength.

RESULTS

Seven new studies were identified. All studies compared different moments for the initial surgical management of spinal injuries. Three recommendations were modified, and three additional recommendations were developed. All achieved strong consensus.

CONCLUSION

The following key recommendations are made. (1) Patients with spinal injuries or deformities with confirmed or assumed neurological deficits which can be treated operatively should undergo surgery as soon as possible (ideally on day 1) if their other medical conditions permit. (2) If suggested by fracture morphology with spinal canal compression or translational injury and if spinal neurological damage cannot be ruled out, assume the presence of spinal neurological damage until it can be ruled out. (3) In the absence of neurological signs and/or symptoms, unstable spinal injuries should be treated by early surgical stabilization based on the patient's overall condition. (4) Depending on the injury, an anterior and/or posterior approach or, in exceptional cases, a halo fixation device can be used to stabilize the cervical spine. (5) Posterior internal fixation should be used as the primary surgical technique for stabilizing injuries to the thoracic and lumbar spine.

Spine injuries among severely injured trauma patients: A retrospective single-center cohort study

BACKGROUNDS AND AIMS

We aimed to determine the incidence and severity of spine injuries among severely injured trauma patients (Injury Severity Score (ISS)/New Injury Severity Score (NISS) > 15) treated in a single tertiary trauma center over 15 years. We also wanted to compare the demographics between patients with and without spine injuries and to determine the mortality of spine-injury patients.

METHODS

Data from the years 2006-2020 from the Helsinki Trauma Registry (HTR), a local trauma registry of the trauma unit of the Helsinki University Hospital (HUH), were reviewed. We divided patients into two groups, namely those with traumatic spine injury (TSI) and those without traumatic spine injury (N-TSI). TSI patients were further subdivided into groups according to the level of injury (cervical, thoracolumbar, or multilevel) and the presence of neurological symptoms.

RESULTS

We included 2529 patients: 1336 (53%) had a TSI and 1193 (47%) had N-TSI. TSI patients were injured more frequently by a high-fall mechanism (37% vs 21%, p < 0.001). Among TSI patients, 38% of high-fall injuries were self-inflicted. High falls, young age, and female gender were overrepresented in spine-injury patients with a self-inflicted injury mechanism. Cervical spine-injury patients were mostly elderly persons injured by a low-energy mechanism.

CONCLUSIONS

Unlike other severely injured trauma patients, severely injured trauma patients with spine injuries are more frequently injured by a high-fall mechanism and self-injury.

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.

Rib fixation for flail chest physiology and the facilitation of safe prone spinal surgery: illustrative case

BACKGROUND

Spine fractures are frequently associated with additional injuries in the trauma setting, with chest wall trauma being particularly common. Limited literature exists on the management of flail chest physiology with concurrent unstable spinal injury. The authors present a case in which flail chest physiology precluded safe prone surgery and after rib fixation the patient tolerated spinal fixation without further issue.

OBSERVATIONS

Flail chest physiology can cause cardiovascular decompensation in the prone position. Stabilization of the chest wall addresses this instability allowing for safe prone spinal surgery.

LESSONS

Chest wall fixation should be considered in select cases of flail chest physiology prior to stabilization of the spinal column in the prone position. Further research is necessary to identify patients that are at highest risk to not tolerate prone surgery.

Time to Surgery in Spinal Trauma: A Meta-Analysis of the World's Literature Comparing High-Income Countries to Low-Middle Income Countries

OBJECTIVE

We conducted a systematic review and meta-analysis to: 1) compare time from traumatic spinal injury (TSI) to operating room (OR) in high-income countries (HICs) versus low-middle-income countries (LMICs), and 2) evaluate hospital length of stay (LOS) in HICs versus LMICs.

METHODS

A systematic literature search was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines involving articles of all languages.

INCLUSION CRITERIA

published between 1991 and 2021, spine trauma population, single country/region, and recorded time from injury to OR. The primary outcome was time from injury to OR, and the secondary outcome was LOS. Means and standard deviations were estimated in a random effects model by DerSimonian and Laird methods.

RESULTS

Of 2367 articles, 163 met the inclusion criteria for systematic review. Regarding time from injury to OR, 23 articles were eligible for meta-analysis; 16 studies were conducted in HICs and 7 in LMICs, comprising 3819 patients with TSI. A significantly shorter mean time from injury to OR was found in HICs (1.92 days, 95% confidence interval 1.44-2.41) compared with LMICs (3.27 days, 95% confidence interval 2.27-4.27) (P = 0.020). Regarding length of stay, 14 articles were eligible for meta-analysis, 10 studies were conducted in HICs and 4 in LMICs, comprising 11,003 patients. There was no difference in LOS between HICs and LMICs (25.76 days vs. 20.48 days, P = 0.140).

CONCLUSIONS

Patients with traumatic spinal injuries in HICs were more likely to undergo earlier surgery compared to patients in LMICs. No difference was found in total LOS between HICs and LMICs. While multiple factors can influence time to surgery, these findings draw attention to the global disparity in spinal trauma care.

Early Versus Late Spine Surgery in Severely Injured Patients-Which Is the Appropriate Timing for Surgery?

STUDY DESIGN

Retrospective cohort study conducted at tertiary spinal trauma referral center.

OBJECTIVE

We aimed to determine if early definitive management of spine fractures in patients admitted to the Intensive Care Unit (ICU) shortens the intubation time and the length of stay (LOS), without increasing mortality.

METHODS

The medical records of all patients admitted to the ICU and submitted to surgical stabilization of spine fractures were reviewed over a 10-year period. Time to surgery, number of fractured vertebrae, degree of neurological injury, Simplified Acute Physiology Score (SAPS II), ASA score and associated trauma were evaluated. Surgeries performed on the first 72 hours after trauma were defined as "early surgeries." Intubation time, LOS on ICU, overall LOS and mortality rate were compared between patients operated early and late.

RESULTS

Fifty patients were included, 21 with cervical fractures, 23 thoracic and 6 lumbar. Baseline characteristics did not differ between patients in both groups. Patients with early surgical stabilization had significantly shorter intubation time, ICU-LOS and overall LOS, with no differences in terms of mortality rate. After multivariate adjustments overall LOS was significantly shorter in patients operated earlier.

CONCLUSIONS

Early spinal stabilization (<72 hours) of severely injured patients is beneficial and shortens the intubation time, ICU-LOS and overall LOS, with no differences in terms of mortality rate. Although some patients may require a delay in treatment due to necessary medical stabilization, every reasonable effort should be made to treat patients with unstable spinal fractures as early as possible.

Predictors of Intensive Care Unit Stay in Patients with Acute Traumatic Spinal Cord Injury Above T6

OBJECTIVE

The objective of this study was to identify factors associated with the intensive care unit (ICU) length of stay (LOS) of patients with an acute traumatic spinal cord injury above T6.

METHODS

We performed a retrospective, observational study of patients admitted to an ICU between 1998 and 2017 (n = 241). The LOS was calculated using a cumulative incidence function, with events of death being considered a competing event. Factors associated with the LOS were analyzed using both a cause-specific Cox proportional hazards regression model and a competing risk model. A multistate approach was also used to analyze the impact of nosocomial infections on the LOS.

RESULTS

A total of 211 patients (87.5%) were discharged alive from the ICU (median LOS = 23 days), and 30 (12.4%) died (median LOS = 11 days). In the multivariate analysis after adjusting for variables collected 4 days after the ICU admission, a higher American Spinal Injury Association motor score (subdistribution hazards ratio [sHR] = 1.01), neurological level C5-C8 (HR = 0,64), and lower Sequential Organ Failure Assessment score (sHR = 0.82) and fluid balance (sHR = 0.95) on day 4 were linked to a lower LOS in this unit. In the multivariate analysis, the onset of an infection was significantly associated with a longer LOS when adjusting for variables collected both at ICU admission (adjusted sHR = 0.62; 95% confidence interval = 0.50-0.77) and on day 4 (adjusted hazards ratio = 0.65; 95% confidence interval = 0.52-0.80).

CONCLUSIONS

After adjusting the data for conventional variables, we identified a lower American Spinal Injury Association motor score, injury level C5-C8, a higher Sequential Organ Failure Assessment score on day 4, a more positive fluid balance on day 4, and the onset of an infection as factors independently associated with a longer ICU LOS.

Early postoperative complications of thoracolumbar fractures in patients with multiple trauma according to the surgical timing

INTRODUCTION AND OBJETCTIVES

Our objective was to compare the rate of complications in thoracolumbar fractures that occurred during the early postoperative period in patients with multiple high-energy trauma according to the time of surgery. As a secondary objective, to estimate which variables were associated with surgery before 72h.

MATERIAL AND METHODS

Retrospective analysis of a series of patients with thoracolumbar fractures and multiple associated injuries in other anatomical regions due to high energy trauma. Surgically treated in an occupational trauma referral center, by the same surgical team and during the period between January 2013 and December 2019.

RESULTS

We analyzed a sample of 40 patients (39 men and 1 woman). The rate of complications was independent of surgical delay (before and after 72h) (p=0.827). There were statistically significant differences between early and later surgery groups in the variables age, systolic blood pressure, initial SOFA score and presence of neurological damage (p=0.014; p=0.029; p=0.032; p=0.012). The overall surgical delay was correlated with the SOFA score (p=0.007).

CONCLUSION

The rate of early postoperative complications did not show significant differences between the early and late surgery groups. We observed that the patients who had been operated before 72h from trauma were younger, had more association with neurological syntoms, presented higher blood pressure values and less physiological damage. Surgical delay was positively correlated with SOFA score on arrival.

Timing of Surgery for Thoracolumbar Spine Trauma: Patients With Neurological Injury

STUDY DESIGN

Large multicenter retrospective cohort study.

OBJECTIVE

The objective of this study was to analyze the effect of fusion timing on inpatient outcomes in a nationally representative population with thoracolumbar fracture and concurrent neurological injury.

SUMMARY OF BACKGROUND DATA

Among thoracolumbar trauma admissions, concurrent neurological injury is associated with greater long-term morbidity. There is little consensus on optimal surgical timing for these patients; previous investigations fail to differentiate thoracolumbar fracture with and without neurological injury.

MATERIALS AND METHODS

We analyzed 19,136 nonelective National Inpatient Sample cases (2004-2014) containing International Classifications of Disease, Ninth Revision, Clinical Modification (ICD-9-CM) diagnosis codes for closed thoracic/lumbar fracture with neurological injury and procedure codes for primary thoracolumbar/lumbosacral fusion, excluding open/cervical fracture. Timing classification from admission to fusion was same-day, 1-2-, 3-6-, and ≥7-day delay. Primary outcomes included in-hospital mortality, complications, and infection; secondary outcomes included total and postoperative length of stay and charges. Logistic regressions and generalized linear models with gamma distribution and log-link evaluated the effect of surgical timing on primary and secondary outcomes, respectively, controlling for age, sex, fracture location, fusion approach, multiorgan system injury severity score, and medical comorbidities.

RESULTS

Patients undergoing surgery ≤72 hours (n=12,845) had the lowest odds of in-hospital cardiac [odds ratio (OR)=0.595; 95% confidence interval (CI), 0.357-0.991] and respiratory complications (OR=0.495; 95% CI, 0.313-0.784) and infection (OR=0.615; 95% CI, 0.390-0.969). No differences were observed between same-day (n=4724) and 1-2-day delay (n=8121) (P>0.05). Lowest odds of hemorrhage or hematoma was observed following 3-6-day delay (OR=0.467; 95% CI, 0.236-0.922). A ≥7-day delay to fusion (n=2,002) was associated with greatest odds of hemorrhage/hematoma (OR=2.019; 1.107-3.683), respiratory complications (OR=1.850; 95% CI, 1.076-3.180), and infection (OR=3.155; 95% CI, 1.891-5.263) and greatest increases in mean postoperative length of stay (4.26% or 35.3% additional days) and charges (163,562 or 71.7% additional US dollars) (P<0.001).

CONCLUSIONS

Patients with thoracolumbar fracture and associated neurological injury who underwent surgery within 3 days of admission experienced fewer in-hospital complications. These benefits may be due to secondary injury mechanism avoidance and earlier mobilization.

Early fixation of traumatic spinal fractures and the reduction of complications in the absence of neurological injury: a retrospective cohort study from the American College of Surgeons Trauma Quality Improvement Program

OBJECTIVE

The optimal timing of operative stabilization of patients with traumatic spinal fractures without spinal cord injury (SCI) has not been established. The challenges of early operative intervention, which may require prone positioning in a patient with multisystem injuries, must be balanced with the disadvantages of prolonged immobilization. The authors set out to define the optimal timing of surgical repair of traumatic spinal fractures in patients without SCI and the effect of delayed repair on the incidence of major complications.

METHODS

A retrospective cohort study was conducted using data derived from the American College of Surgeons Trauma Quality Improvement Program. Adult trauma patients who underwent operative fixation of a spinal fracture within 7 days of admission were included. Patients with SCI were excluded. The primary outcome was the occurrence of a major complication. Secondary outcomes included death and length of stay. Restricted cubic splines were used to model the nonlinear effects of time to spinal fixation and determine a threshold beyond which stabilization was associated with a higher rate of major complications. Logistic regression and propensity score matching were then used to derive estimates for the association between delayed fixation and major complications.

RESULTS

The authors identified 19,310 patients treated at 389 centers who met the inclusion criteria. Modeling identified fixation beyond 24 hours as a risk for major complications. Adjusting for potential confounders using multivariable logistic regression showed that late fixation was associated with a 1.30 (95% CI 1.15-1.46) times increased odds of developing a major complication. After propensity score matching, late fixation remained associated with a 1.25 (95% CI 1.13-1.39) times increased risk of experiencing a major complication.

CONCLUSIONS

In the absence of clear contraindications, surgeons should strive to stabilize traumatic spinal fractures without SCI within 24 hours. Early fixation can be expected to reduce major complications by 25%-30%.

Comparison of Preoperative Pedicle Screw Measurement Between Computed Tomography and Magnet Resonance Imaging

BACKGROUND

Pedicle screw fixation is commonly used in the treatment of spinal pathologies. While the biomechanical factors that affect bone fixation have been frequently described, questions remain as to which imaging modality is the ideal medium for preoperative planning. Due to its perceived superiority in assessing bony changes, computed tomography (CT) scan is assumed to be the gold standard for preparative planning, and we hypothesize that magnetic resonance imaging (MRI) is sufficiently accurate to predict screw length and diameter compared to CT.

METHODS

We retrospectively measured the length and diameter of vertebral bodies in the lumbar region in both MRI and CT and tested for differences between the modalities as well as for confounding effects of age, sex, and the presence of spondyloarthrosis.

RESULTS

We found a significant difference in pedicle screw length between CT and MRI measurements for both sides. For the left pedicle, the mean difference was 1.89 mm (95% confidence interval [CI] -3.03 to -0.75; P < .002), while for the right pedicle, the mean difference was 2.05 mm (95% CI -3.27 to -0.84; P = .001). We also found a significant difference in diameter measurements between CT and MRI for the left pedicle (0.53 mm; 95% CI 0.13 to 0.93; P = .011) but not for the right pedicle (0.36 mm; 95% CI -0.06 to 0.78; P = .094). We identified no significant effect of sex, age or spondyloarthrosis on the results (P > .05).

CONCLUSIONS

Pedicle screw planning measurements were more accurate using CT images compared to MRI images. CT scan remains the gold standard for pedicle screw planning in trauma surgery. When using MRI images, the surgeon should be aware of the differences in screw length and diameter compared to CT in order to avoid intra- and postoperative risks.

Massive hemothorax due to bleeding from thoracic spinal fractures: a case series and systematic review

BACKGROUND

Massive hemothorax secondary to thoracic spinal fractures is rare, and its clinical characteristics, treatment, and prognosis are unknown. We present two cases of thoracic spinal fracture-induced massive hemothorax and a systematic review of previously reported cases.

METHODS

This study included patients with traumatic hemothorax from thoracic spinal fractures at a Japanese tertiary care hospital. A systematic review of published cases was undertaken through searches in PubMed, EMBASE, and ICHUSHI from inception to October 13, 2019.

RESULTS

Case 1: An 81-year-old man developed hemodynamic instability from a right hemothorax with multiple rib fractures following a pedestrian-vehicle accident; > 1500 mL blood was evacuated through the intercostal drain. Thoracotomy showed hemorrhage from a T8-burst fracture, and gauze packing was used for hemostasis. Case 2: A 64-year-old man with right hemothorax and hypotension after a fall from height had hemorrhage from a T7-burst fracture, detected on thoracotomy, which was sealed with bone wax. Hypotension recurred during transfer; re-thoracotomy showed bleeding from a T7 fracture, which was packed with bone wax and gauze for hemostasis. The systematic review identified 10 similar cases and analyzed 12 cases, including the abovementioned cases. Inferior part of thoracic spines was prone to injury and induced right-sided hemothorax. Most patients developed hemodynamic instability, and some sustained intra-transfer hemorrhage; direct compression (gauze packing, bone wax, and hemostatic agents) was the commonest hemostatic procedure. The mortality rate was 33.3%.

CONCLUSIONS

Hemothorax due to thoracic spinal fracture can be fatal. Thoracotomy with direct compression is necessary in hemodynamically unstable patients.

Early Spinal Injury Stabilization in Multiple-Injured Patients: Do All Patients Benefit?

Background: Thoracolumbar spine fractures in multiple-injured patients are a common injury pattern. The appropriate timing for the surgical stabilization of vertebral fractures is still controversial. The purpose of this study was to analyse the impact of the timing of spinal surgery in multiple-injured patients both in general and in respect to spinal injury severity. Methods: A retrospective analysis of multiple-injured patients with an associated spinal trauma within the thoracic or lumbar spine (injury severity score (ISS) >16, age >16 years) was performed from January 2012 to December 2016 in two Level I trauma centres. Demographic data, circumstances of the accident, and ISS, as well as time to spinal surgery were documented. The evaluated outcome parameters were length of stay in the intensive care unit (ICU) (iLOS) and length of stay (LOS) in the hospital, duration of mechanical ventilation, onset of sepsis, and multiple organ dysfunction syndrome (MODS), as well as mortality. Statistical analysis was performed using SPSS. Results: A total of 113 multiple-injured patients with spinal stabilization and a complete dataset were included in the study. Of these, 71 multiple-injured patients (63%) presented with an AOSpine A-type spinal injury, whereas 42 (37%) had an AOSpine B-/C-type spinal injury. Forty-nine multiple-injured patients (43.4%) were surgically treated for their spinal injury within 24 h after trauma, and showed a significantly reduced length of stay in the ICU (7.31 vs. 14.56 days; p < 0.001) and hospital stay (23.85 vs. 33.95 days; p = 0.048), as well as a significantly reduced prevalence of sepsis compared to those surgically treated later than 24 h (3 vs. 7; p = 0.023). These adverse effects were even more pronounced in the case where cutoffs were increased to either 72 h or 96 h. Independent risk factors for a delay in spinal surgery were a higher ISS (p = 0.036), a thoracic spine injury (p = 0.001), an AOSpine A-type spinal injury (p = 0.048), and an intact neurological status (p < 0.001). In multiple-injured patients with AOSpine A-type spinal injuries, an increased time to spinal surgery was only an independent risk factor for an increased LOS; however, in multiple-injured patients with B-/C-type spinal injuries, an increased time to spinal surgery was an independent risk factor for increased iLOS, LOS, and the development of sepsis. Conclusion: Our data support the concept of early spinal stabilization in multiple-injured patients with AOSpine B-/C-type injuries, especially of the thoracic spine. However, in multiple-injured patients with AOSpine A-type injuries, the beneficial impact of early spinal stabilization has been overemphasized in former studies, and the benefit should be weighed out against the risk of patients’ deterioration during early spinal stabilization.

Possible advantages of early stabilization of spinal fractures in multiply injured patients with leading thoracic trauma - analysis based on the TraumaRegister DGU®

Background

Major trauma often comprises fractures of the thoracolumbar spine and these are often accompanied by relevant thoracic trauma. Major complications can be ascribed to substantial simultaneous trauma to the chest and concomitant immobilization due to spinal instability, pain or neurological dysfunction, impairing the respiratory system individually and together. Thus, we proposed that an early stabilization of thoracolumbar spine fractures will result in significant benefits regarding respiratory organ function, multiple organ failure and length of ICU / hospital stay.

Methods

Patients documented in the TraumaRegister DGU®, aged ≥16 years, ISS ≥ 16, AIS_Thorax ≥ 3 with a concomitant thoracic and / or lumbar spine injury severity (AIS_Spine) ≥ 3 were analyzed. Penetrating injuries and severe injuries to head, abdomen or extremities (AIS ≥ 3) led to patient exclusion. Groups with fractures of the lumbar (LS) or thoracic spine (TS) were formed according to the severity of spinal trauma (AIS_spine): AIS_LS = 3, AIS_LS = 4–5, AIS_TS = 3 and AIS_TS = 4–5, respectively.

Results

1740 patients remained for analysis, with 1338 (76.9%) undergoing spinal surgery within their hospital stay. 976 (72.9%) had spine surgery within the first 72 h, 362 (27.1%) later on. Patients with injuries to the thoracic spine (AIS_TS = 3) or lumbar spine (AIS_LS = 3) significantly benefit from early surgical intervention concerning ventilation time (AIS_LS = 3 only), ARDS, multiple organ failure, sepsis rate (AIS_TS = 3 only), length of stay in the intensive care unit and length of hospital stay. In multiple injured patients with at least severe thoracic spine trauma (AIS_TS ≥ 4) early surgery showed a significantly shorter ventilation time, decreased sepsis rate as well as shorter time spend in the ICU and in hospital.

Conclusions

Multiply injured patients with at least serious thoracic trauma (AIS_Thorax ≥ 3) and accompanying spine trauma can significantly benefit from early spine stabilization within the first 72 h after hospital admission. Based on the presented data, primary spine surgery within 72 h for fracture stabilization in multiply injured patients with leading thoracic trauma, especially in patients suffering from fractures of the thoracic spine, seems to be beneficial.

Time-sensitive ambulatory orthopaedic soft-tissue surgery paradigms during the COVID-19 pandemic

Purpose

Timing of surgery for orthopaedic injuries continues to evolve, as an improved understanding of biology, healing, and technological advances continues to challenge historical norms. With the growing COVID-19 pandemic stretching limited healthcare resources, postponing surgery becomes an inevitable and unenviable task for most orthopaedic surgeons, and a shift in outpatient paradigms is required to mitigate poor outcomes in patients.

Methods

A scoping review of five databases on surgical timing and orthopaedic soft-tissue injuries was performed. All randomized controlled trials, longitudinal cohort studies, retrospective case series, systematic reviews, meta-analyses, and expert opinions were included for review, with 65 studies meeting the inclusion criteria.

Results

Better outcomes appear to be associated with early surgery for subluxations (< 1 week), recurrent dislocations (> 2 episodes), ligamentous and tendinous injuries (< 2 weeks), and bony avulsion injuries (< 3 weeks). Spinal conditions with neurological compromise should be operated on within 24 hours and spinal instability within 72 hours to reduce the risk of complications and poor outcomes.

Conclusion

Most soft-tissue orthopaedic injuries can be managed with outpatient ambulatory surgery in a semi-elective setting. As the paradigm for outpatient surgery shifts due to technological advances and the COVID-19 pandemic, it is critical for surgeons to time their surgery appropriately to maintain the high standards of orthopaedic practice.

Spinal Injury Without Neurological Symptoms in Severely Injured Patients: Impact on the Length of Stay?

BACKGROUND

The impact of spinal injuries on clinical outcome in most severely injured patients is currently being controversially discussed. At the same time, most of the studies examine patients with post-traumatic neurological disorders. The aim of this study was therefore to analyse severely injured patients with spinal injuries but without neurological symptoms with regard to their clinical outcome. Here the focus was then on the question, whether spinal injury is an independent risk factor increasing length of stay in the intensive care unit and in the hospital in total.

MATERIAL AND METHODS

Data of the TraumaRegister DGU^® were retrospectively analysed. Inclusion criteria were: Injury Severity Score ≥ 16, primary admission, age ≥ 16 years, time interval 2009 - 2016, and a full data set on length of stay in the hospital and the intensive care unit, respectively. Following a univariate analysis in the first step, independent risk factors for the length of stay in the intensive care unit and in the hospital in total were investigated using a multivariate regression analysis.

RESULTS

98,240 patients met the inclusion criteria. In this population, patients with Abbreviated Injury Scale (AIS) 2 and 3 spinal injuries were significantly younger (up to 60 years), and injuries were significantly more commonly caused by falls from a great height and traffic accidents (age ≤ 60 years: AIS_Spine 0: 58.4%, AIS_Spine 3: 65%; p < 0.001). Multivariate analysis showed that spinal injury without neurological symptoms is an independent risk factor for increased length of stay in the intensive care unit (odds ratio: + 1.1 d) and in the hospital in total (AIS 3 odds ratio: + 3.4 d).

CONCLUSION

It has been shown for the first time that spinal injury without initial neurological symptoms has a negative impact on the length of stay of most severely injured patients in the intensive care unit and in the hospital in total and thus represents an independent risk factor in this group of patients.

Less Invasive Surgery is Feasible in the Management of Traumatic Thoracolumbar Fractures in Isolated and Polytrauma Injury

Background

Less invasive stabilization systems (LISSs) have gained popularity. However, limited quality of life (QOL) and clinical outcome data exist for trauma patients treated with LISSs. The objective of this study is to describe QOL and outcome for posterior percutaneous pedicle screw fixation in the management of traumatic thoracolumbar fractures.

Methods

Between January 2006 and December 2011, data from all patients treated with a posterior percutaneous pedicle screw fixation technique for thoracolumbar fractures were collected and analyzed. Sixty-nine patients met the inclusion criteria. Additional vertebral reduction and cement augmentation was used in 25 patients, when there was more than 50% of vertebral body comminution.

Results

Mean follow up of 19 months (range = 6-49 months). Fifty-one percent of the study population consisted of polytrauma patients, with 22% having injury severity score ≥ 15. In 6 cases (8.7%) there were perioperative complications. Response rate for the follow-up health survey was 78%, with a satisfactory overall median EuroQuol score of 0.811 (Q1-Q3 95% confidence interval = 0.709-0.897).

Conclusions

Posterior percutaneous pedicle screw fixation proves to be effective in the management of traumatic thoracolumbar fractures, with a good overall functional outcome. Percutaneous techniques that reduce perioperative morbidity are an alternative approach well suited for damage control orthopaedics, as long as there are no neurological deficits. Especially in polytrauma patients with spine fractures, the spinal column can be stabilized in an emergency setting, while limiting the risks of "a second hit" at the patients' already frail condition.

Timing of surgical fixation in traumatic spinal fractures: A systematic review

BACKGROUND

The optimal timing of fracture fixation following spinal injury is controversial. Many spinal fractures occur as part of polytrauma requiring a complex management strategy. Whilst the decision to stabilize unstable spinal column injuries is without debate, the duration between injury and definitive fixation can impact on the incidence of post-operative complications. This study was designed to systemically summarize and compare the complication profile of early vs late stabilization of spinal injuries, in an attempt to unveil an appropriate treatment protocol for traumatic spinal fractures.

METHODS

A comprehensive search strategy was performed on the PubMed, Cochrane, and Google Scholar databases using key words. The search strategy provided 1120 results. Forty-six articles were reviewed for full-text. Reference lists were analysed for potential additional texts.

RESULTS

Sixteen articles met the inclusion criteria and were included for systematic review. Studies were controversial and the overall result was inconclusive. Several studies favour early stabilisation to reduce post-surgical complication rates, especially in cases of patients with high Injury Severity Scale (ISS) scores. However, this is challenged by a small number of studies reporting a higher mortality rate in the early-stabilisation cohort.

CONCLUSION

Due to limited studies and a small overall cohort, the authors would cautiously recommend the early surgical fixation of unstable spine fractures in the stable trauma patient. For severely injured patients, the discordance among literature warrants the need for further investigation.

Acute Spinal Cord Injury: A Systematic Review Investigating miRNA Families Involved

Acute traumatic spinal cord injury (SCI) involves primary and secondary injury mechanisms. The primary mechanism is related to the initial traumatic damage caused by the damaging impact and this damage is irreversible. Secondary mechanisms, which begin as early as a few minutes after the initial trauma, include processes such as spinal cord ischemia, cellular excitotoxicity, ionic dysregulation, and free radical-mediated peroxidation. SCI is featured by different forms of injury, investigating the pathology and degree of clinical diagnosis and treatment strategies, the animal models that have allowed us to better understand this entity and, finally, the role of new diagnostic and prognostic tools such as miRNA could improve our ability to manage this pathological entity. Autopsy could benefit from improvements in miRNA research: the specificity and sensitivity of miRNAs could help physicians in determining the cause of death, besides the time of death.

Does the Coexistence of Multiple Segmental Rib Fractures in Polytrauma Patients Presenting With "Major" Vertebral Fracture Affect Care and Acute Outcomes?

OBJECTIVE

To determine whether operating on "major" vertebral fractures leads to premature abortion of surgery and/or other acute cardiopulmonary complications.

DESIGN

Retrospective review.

CLINICAL SETTING

Level 1 trauma center.

PATIENTS/PARTICIPANTS AND INTERVENTION

We retrospectively queried our institutional Trauma Rregistry for all cases presenting with concomitant rib fractures and surgically managed vertebral fractures.

MAIN OUTCOME MEASUREMENTS

The main outcomes included the surgical outcome (aborted vs. successfully performed), total and Intensive Care Unit length of stay (LOS), adverse discharge, mortality, and functional outcomes.

RESULTS

We found 57 cases with concomitant segmental rib fractures and surgically managed vertebral fractures. Seven patients (12%) received a rib fixation, of which 1 received before vertebral fixation and 6 after. Importantly, 4 vertebral fixation cases (7.02%) had to be aborted intraoperatively because of the inability to tolerate prone positioning for surgery. For case-control analysis, we performed propensity score matching to obtain matched controls, that is, cases of vertebral fixation but no rib fractures. On matched case-control analysis, patients with concomitant segmental rib fractures and vertebral fractures were found to have higher Intensive Care Unit LOS [median = 3 days (Inter-Quartile Range = 0-9) versus. 8.4 days, P = 0.003], whereas total LOS, frequency of complete, incomplete or functional spinal cord injury, discharge to rehab, and discharge to nursing home were found to be similar between the 2 groups.

CONCLUSION

Our findings demonstrate that segmental rib fractures with concomitant vertebral fractures undergoing surgical treatment represent a subset of patients that may be at increased risk of intraoperative cardio-pulmonary complications and rib fixation before prone spine surgery for cases in which the neurological status is stable is reasonable.

Transportation mode and timing of spinal cord decompression and stabilization in patients with traumatic spinal cord injury in Iran

STUDY DESIGN

Cross-sectional retrospective study.

OBJECTIVE

To describe the transportation mode to hospital and timing of spinal cord decompression and stabilization (D&S), length of hospital stay, frequency of pressure injuries, and sepsis during hospitalization.

SETTING

Brain and Spinal Injury Research Center, Tehran, Iran.

METHODS

Eight hundred and thirty patients with traumatic spinal cord injury (TSCI) were enrolled. Mode of transportation and length of time to reach the first hospital, length of hospital stay (LOS), and the time span between hospital arrival and decompression and stabilization (D&S) were recorded.

RESULTS

Fifty-nine percent of the enrolled individuals were transported to the first hospital by ambulance, while 41% were transferred by vehicles without medical equipment and personnel. Median length of time to reach the first hospital was 1 h for both ambulance and non-equipped car groups, with no statistically significant difference (p = 0.1). Median LOS, frequencies of pressure injuries, and sepsis based on the injury levels were not significantly different between two transportation modalities. One hundred and seventy-seven individuals had early surgery, and 254 had late surgery. Median LOS was 13 days in the early surgery group and 20 days in the late surgery group (p = 0.002). Frequencies of pressure injuries and sepsis were not significantly different between the late and early surgery groups for various injury levels.

CONCLUSION

About 59% of our patients had been transported to a hospital by non-medical personnel. Those with late surgery had significantly longer LOS. Improving TSCI patients' transportation method and early surgical interventions, if possible, may be considered.

Management of Mangled Extremities and Orthopaedic War Injuries

In 16 years of conflict, primarily in Iraq and Afghanistan, wounded warriors have primarily been subjected to blast type of injuries. Evacuation strategies have led to unprecedented survival rates in blast-injured soldiers, resulting in large numbers of wounded warriors with complex limb trauma. Bone and soft tissue defects have resulted in increased use of complex reconstructive algorithms to restore limbs and function. In addition, in failed salvage attempts, advances in amputation options are being developed. In this review, we summarize state-of-the-art limb-salvage methods for both soft tissue and bone. In addition, we discuss advances in diagnostic methods with development of personalized clinical decision support tools designed to optimize outcomes after severe blast injuries. Finally, we present new advances in osteointegrated prostheses for above-knee amputations.

Early Definitive Fracture Fixation is Safely Performed in the Presence of an Open Abdomen in Multiply Injured Patients

OBJECTIVE

To investigate the safety and feasibility of performing definitive fracture fixation in multiply injured patients in the presence of an open abdomen after laparotomy.

DESIGN

Retrospective observational cohort study.

SETTING

Level-I academic trauma center.

PATIENTS

Adult polytrauma patients with the presence of an open abdomen after "damage control" laparotomy and associated major fractures of long bones, acetabulum, pelvis, or spine, requiring surgical repair (n = 81).

INTERVENTION

Timing of definitive fracture fixation in relation to the timing of abdominal wall closure.

MAIN OUTCOME MEASURE

Incidence of orthopedic surgical site infections.

RESULTS

During a 15-year time window from January 1, 2000 until December 31, 2014, we identified a cohort of 294 consecutive polytrauma patients with an open abdomen after laparotomy. Surgical fixation of associated fractures was performed after the index laparotomy in 81 patients. In group 1 (n = 32), fracture fixation occurred significantly sooner despite a concurrent open abdomen, compared with group 2 (n = 49) with abdominal wall closure before fixation (mean 4.4 vs. 11.8 days; P = 0.01). The incidence of orthopaedic surgical site infections requiring a surgical revision was significantly lower in group 1 (3.1%) compared to group 2 (30.6%; P = 0.002).

CONCLUSIONS

Definitive fracture fixation in the presence of an open abdomen is performed safely and associated with a significant decrease in clinically relevant surgical site infections, compared with delaying fracture fixation until abdominal wall closure. These data suggest that the strategy of imposing a time delay in orthopaedic procedures while awaiting abdominal wall closure is unjustified.

Surgical timing for cervical and upper thoracic injuries in patients with polytrauma

OBJECTIVE

Few studies have investigated the advantages of early spinal stabilization in the patient with polytrauma in terms of reduction of morbidity and mortality. Previous analyses have shown that early stabilization may reduce ICU stay, with no effect on complication rates.

METHODS

The authors prospectively observed 340 polytrauma patients with an Injury Severity Score (ISS) of greater than 16 at a single Level 1 trauma center who were treated in accordance with a protocol termed “early appropriate care,” which emphasizes operative treatment of various fractures within 36 hours of injury. Of these patients, 46 had upper thoracic and/or cervical spine injuries. The authors retrospectively compared patients treated according to protocol versus those who were not. Continuous variables were compared using independent t-tests and categorical variables using Fisher’s exact test. Logistic regression analysis was performed to account for baseline confounding factors.

RESULTS

Fourteen of 46 patients (30%) did not undergo surgery within 36 hours. These patients were significantly more likely to be older than those in the protocol group (53 vs 38 years, p = 0.008) and have greater body mass index (BMI; 33 vs 27, p = 0.02), and they were less likely to have a spinal cord injury (SCI) (82% did not have an SCI vs 44% in the protocol group, p = 0.04). In terms of outcomes, patients in the protocol-breach group had significantly more total ventilator days (13 vs 6 days, p = 0.02) and total ICU days (16 vs 9 days, p = 0.03). Infection rates were 14% in the protocol-breach group and 3% in the protocol group (p = 0.2) Total complications trended toward being statistically significantly more common in the protocol-breach group (57% vs 31%). After controlling for potential confounding variables by logistic regression (including age, sex, BMI, race, and SCI), total complications were significantly (p < 0.05) greater in the protocol-breach group (OR 29, 95% CI 1.9–1828). This indicates that the odds of developing “any complication” were 29 times greater if treatment was delayed more than 36 hours.

CONCLUSIONS

Early surgical stabilization in the polytrauma patient with a cervical or upper thoracic spine injury is associated with fewer complications and improved outcomes. Hospitals may consider the benefit of protocols that promote early stabilization in this patient population.

Spine Trauma-What Are the Current Controversies?

Although less common than other musculoskeletal injuries, spinal trauma may lead to significantly more disability and costs. During the last 2 decades there was substantial improvement in our understanding of the basic patterns of spinal fractures leading to more reliable classification and injury severity assessment systems but also rapid developments in surgical techniques. Despite these advancements, there remain unresolved issues concerning the management of these injuries. At this moment there is persistent controversy within the spinal trauma community, which can be grouped under 6 headings. First of all there is still no unanimity on the role and timing of medical and surgical interventions for patients with associated neurologic injury. The same is also true for type and timing of surgical intervention in multiply injured patients. In some common injury types like odontoid fractures and burst type (A3-A4) fractures in thoracolumbar spine, there is wide variation in practice between operative versus nonoperative management without clear reasons. Also, the role of different surgical approaches and techniques in certain injury types are not clarified yet. Methods of nonoperative management and care of elderly patients with concurrent complex disorders are also areas where there is no consensus. In this overview article the main reasons for these controversies are reviewed and the possible ways for resolutions are discussed.

Does Surgical Intervention or Timing of Surgery Have an Effect on Neurological Recovery in the Setting of a Thoracolumbar Burst Fracture?

Traumatic thoracolumbar burst fractures are one of the most common forms of spinal trauma with the majority occurring at the junctional area where mechanical load is maximal (AOSpine Thoracolumbar Spine Injury Classification System Subtype A3 or A4). Burst fractures entail the involvement of the middle column, and therefore, they are typically associated with bone fragment in the spinal canal, which may cause compression of the spinal cord, conus medullaris, cauda equina, or a combination of these. Fortunately, approximately half of the patients with thoracolumbar burst fractures are neurologically intact due to the wide canal diameter. Recent evidences have revealed that functional outcomes in the long term may be equivalent between operative and nonoperative management for neurologically intact thoracolumbar burst fractures. Nevertheless, consensus has not been met regarding the optimal treatment strategy for those with neurological deficits. The present review article summarizes the contemporary evidences to discuss the role of nonoperative management in the presence of neurological deficits and the optimal timing of decompression surgery for neurological recovery. In summary, although operative management is generally recommended for thoracolumbar fracture with significant neurological deficits, the evidence is weak, and nonoperative management can also be an option for those with solitary radicular symptoms. With regards to timing of operative management, high-quality studies comparing early and delayed intervention are lacking. Extrapolating from the evidence in cervical spine injury leads to an assumption that early intervention would also be beneficial for neurological recovery, but further studies are warranted to answer these questions.

Thoracolumbar fractures without neurological impairment: A review of diagnosis and treatment

An appropriate protocol and unified management of thoracolumbar fractures without neurological impairment has not been well defined.

This review attempts to elucidate some controversies regarding diagnostic tools, the ability to define the most appropriate treatment of classification systems and the evidence for conservative and surgical methods based on the recent literature.

Correlation Between Timing of Surgery and Outcome in ThoracoLumbar Fractures: Does Early Surgery Influence Neurological Recovery and Functional Restoration? A Multivariate Analysis of Results in Our Experience

BACKGROUND

Treatment for spinal trauma is affected by both nonmodifiable and modifiable variables. The aim of this study was to compare early surgery with intermediate and late surgery to determine the benefits of spinal reconstruction in neurological recovery and functional restoration in patients with thoracolumbar fractures.

METHODS

In order to identify correlations between treatment timing, fracture site, neurological recovery, American Spinal Injury Association (ASIA) score restoration, and rehabilitation prognosis in patients with thoracic and lumbar fractures, we conducted a multivariate analysis of the results of surgery, at our institution, in 166 consecutive patients with unstable thoracolumbar fractures with or without neurological impairment. We conducted a literature review (1988-2012) and compared our results with those already published.

RESULTS

Regardless of the location and type of fracture, early surgery resulted in a reduction of median hospital and intensive care unit (ICU) length of stay, as well as a reduction of nosocomial complications. Regardless of the type of fracture and preoperative ASIA score, thoracic fractures had the worst outcome. Early treatment seemed to have better results, depending on the preoperative ASIA score.

CONCLUSION

Early surgery in patients with thoracolumbar fractures with incomplete neurological damage could positively affect neurological recovery, functional restoration, length of hospital and ICU stay, and associated comorbidity. Thoracic fractures had the worst outcome. Early surgery seemed to have better results if the initial ASIA score was good. The better the ASIA score on admission, the better was the outcome. Surgical timing did not affect the outcome when the ASIA score was A or E.

Is Early Appropriate Care of axial and femoral fractures appropriate in multiply-injured elderly trauma patients?

BACKGROUND

Previous work established resuscitation parameters that minimize complications with early fracture management. This Early Appropriate Care (EAC) protocol was applied to patients with advanced age to determine if they require unique parameters to mitigate complications.

METHODS

Between October 2010 and March 2013, 376 consecutive skeletally mature patients with unstable fractures of the pelvis, acetabulum, thoracolumbar spine, and/or proximal or diaphyseal femur fractures were treated at a level I trauma center and were prospectively studied. Patients aged ≤30 years (n = 114), 30 to 60 years (n = 184), and ≥60 years (n = 37) with Injury Severity Scores (ISS) ≥16 and unstable fractures of the pelvis, acetabulum, spine, and/or diaphyseal femur were treated within 36 h, provided they showed evidence of adequate resuscitation. ISS, Glasgow Coma Scale (GCS), and American Society of Anesthesiologists (ASA) classification were determined. Lactate, pH, and base excess (BE) were measured at 8-h intervals. Complications included pneumonia, pulmonary embolism (PE), acute renal failure, acute respiratory distress syndrome (ARDS), multiple organ failure (MOF), deep vein thrombosis, infection, sepsis, and death.

RESULTS

Patients ≤30 years old (y/o) were more likely to sustain gunshot wounds (p = 0.039), while those ≥60 y/o were more likely to fall from a height (p = 0.002). Complications occurred at similar rates for patients ≤30 y/o, 30 to 60 y/o, and ≥60 y/o. There were no differences in lactate, pH, or BE at the time of surgery. For patients ≤30 y/o, there were increased overall complications if pH was <7.30 (p = 0.042) or BE <-6.0 (p = 0.049); patients ≥60 y/o demonstrated more sepsis if BE was <-6.0 (p = 0.046).

CONCLUSIONS

EAC aims to definitively manage axial and femoral shaft fractures once patients have been adequately resuscitated to minimize complications. EAC is associated with comparable complication rates in young and elderly patients. Further study is warranted with a larger sample to further validate EAC in elderly patients.

Large-magnitude Pelvic and Retroperitoneal Tissue Damage Predicts Organ Failure

BACKGROUND

Pelvic and retroperitoneal trauma is a major cause of morbidity and mortality in multiply injured patients. The Injury Severity Score (ISS) has been criticized for underrepresenting and inaccurately defining mechanical injury. The influence of pelvic injury volume on organ dysfunction and multiple organ failure (MOF) has not been described. Through the use of CT, this investigation sought to precisely define volumes of mechanical tissue damage by anatomic region and examine its impact on organ failure.

QUESTIONS/PURPOSES

(1) Do patients with MOF have a greater volume of pelvic and retroperitoneal tissue damage when compared with those without MOF? (2) In patients who sustained pelvic trauma, does the magnitude of pelvic injury differ in patients with MOF? (3) Does the magnitude of organ dysfunction correlate with pelvic tissue damage volume?

METHODS

Seventy-four multiply injured patients aged 18 to 65 years with an ISS ≥ 18 admitted to the intensive care unit for a minimum of 6 days with complete admission CT scans were analyzed. Each identifiable injury in the head/neck, chest, abdomen, and pelvis underwent volumetric determination using CT to generate regional tissue damage volume scores. Primary outcomes were the development of MOF as measured by the Denver MOF score and the degree of organ dysfunction by utilization of the Sequential Organ Failure Assessment (SOFA) score. Mean pelvic and retroperitoneal tissue damage volumes were compared in patients who developed MOF and those who did not develop MOF using Student's t-test. Among patients who sustained pelvic injuries, we compared mean volume of tissue damaged in patients who developed MOF and those who did not. We assessed whether there was a correlation between organ dysfunction, as measured by the SOFA score as a continuous variable, and the volume of pelvic and retroperitoneal tissue damage using the Pearson product-moment correlation coefficient.

RESULTS

The average volume of tissue damage was greater in patients with MOF when compared with those without (MOF: 685.667 ± 1081.344; non-MOF: 195.511 ± 381.436; mean difference 490.156 cc [95% confidence interval {CI}, 50.076-930.237 cc], p = 0.030). Among patients who sustained pelvic injuries, those with MOF had higher average tissue damage volumes than those without MOF (MOF: 1322.000 ± 1197.050; non-MOF: 382.750 ± 465.005; mean difference 939.250 [95% CI, 229.267-1649.233], p = 0.013). Organ dysfunction (SOFA score) correlated with higher volumes of pelvic tissue damage (r = 0.570, p < 0.001).

CONCLUSIONS

This investigation demonstrated that greater degrees of pelvic and retroperitoneal tissue damage calculated from injury CT scans in multiply injured patients is associated with more severe organ dysfunction and an increased risk of developing MOF. Early identification of polytrauma patients at risk of MOF allows clinicians to implement appropriate resuscitative strategies early in the disease course. Improved stratification of injury severity and a patient's anticipated clinical course may aid in the planning and execution of staged orthopaedic interventions. Future avenues of study should incorporate the ischemic/hypoperfusion component of pelvic injury in conjunction with the mechanical component presented here for improved stratification of multiply injured patients at higher risk of MOF.

Percutaneous pedicle screw fixation for an unstable thoracic spine fracture after a traumatic degloving injury

Unstable spinal fractures require urgent surgical intervention to relieve compression of the spinal cord, correct spinal deformity, stabilise the spine and prevent further neurological injury. We report the case of a young man with a thoracic chance fracture in the setting of a devastating degloving injury, whose fracture was stabilised using minimally invasive, percutaneous pedicle screw fixation. We discuss the advantages of using a minimally invasive technique for spinal fixation and its role in the treatment of complicated, multisystem trauma patients.

[Value of clinical key symptoms in the primary treatment of severely injured patients]

BACKGROUND

The initial diagnostic procedure of severely injured patients in the emergency room (ER) during the primary survey is first and foremost a clinical examination. The clinical S3 guidelines provide recommendations for the treatment of patients with severe and multiple injuries.

OBJECTIVES

The study was performed to investigate the reliability of clinical key symptoms or red flags registered in the ER that lead to further diagnostic or therapeutic procedures.

MATERIAL AND METHODS

An evaluation of key symptoms as a synopsis of the current literature considering aspects of probability calculation and medical experience was carried out.

RESULTS

Key symptoms registered during the clinical examination are not sufficiently safe to be solely relied upon for further diagnostic and therapeutic decisions. This confirms the sense of purpose of the strict approach according to the advanced trauma life support (ATLS) algorithm. Red flags can serve as a warning to focus on relevant injuries early on. A rational imaging diagnostic procedure must follow.

Current Concepts in Orthopedic Management of Multiple Trauma

Multiple trauma patients frequently present challenging clinical scenarios with musculoskeletal injuries being the most common indications for surgical procedures in these patients. Despite our substantial knowledge, a universally approved objective definition for “multiple trauma” is yet to be delineated. Several controversial aspects of economics, pathophysiology, animal models, diagnosis, management and outcome of patients with multiple trauma have recently been explored and although some progress has been made, it seems that the available evidence is still inconclusive in some occasions. This manuscript revisits several current concepts of multiple trauma that have been the focus of recent investigation. We aim to provide the reader with an updated perspective based on the most recently published literature in the field of multiple trauma.

Damage control in thoracic and lumbar unstable fractures in polytrauma. Systematic review

<p>The objective of this systematic review was to integrate the information from existing studies to determine the level of evidence and grade of recommendation of the implementation of damage control in unstable thoracic and lumbar fractures in polytraumatized patients. Eighteen papers were collected from different databases by keywords and Mesh terms; the level of evidence and grade of recommendation, the characteristics of the participants, the time of fracture fixation, the type of approach and technique used, the length of stay in the intensive care unit, the days of dependence on mechanical ventilator, and the incidence of complications in patients were assessed. The largest proportion of the studies were classified as level 4 evidence and grade C of recommendation which is favorable to the implementation of damage control in unstable thoracic and lumbar fractures in polytraumatized patients as a positive recommendation, although not conclusive. Most papers advocate fracture stabilization within 72 hours of the injury which is associated with a lower incidence of complications, hospital stay, stay in the intensive care unit and lower mortality.</p>
