Management of Traumatic Femur Fractures: A Focus on the Time to Intramedullary Nailing and Clinical Outcomes.

BACKGROUND: Femur shaft factures (FSF) are common injuries following high-energy mechanisms mainly involving motor vehicle crashes (MVC). We evaluated the timings of nailing management and analyzed the pattern of fracture union and outcome in a level 1 trauma center. METHODS: This was a retrospective observational study of all the admitted trauma patients who sustained femoral fractures between January 2016 and September 2020. Data were analyzed and compared based on time to Intramedullary Nailing (IMN) (<12 h, 12-24 h and >24 h) and outcomes of FSF (union, delayed union and nonunion). RESULTS: A total of 668 eligible patients were included in the study, of which the majority were males (90.9%) with a mean age of 34.5 ± 15.8, and 54% of the injuries were due to MVCs. The chest (35.8%) was the most commonly associated injured body region, followed by the pelvis (25.9%) and spine (25.4%). Most of femur fractures (93.3%) were unilateral, and 84.4% were closed fractures. The complete union of fractures was observed in 76.8% of cases, whereas only 4.2% and 3.3% cases had delayed union and nonunion, respectively, on the clinical follow-up. Patients in the delayed IMN (>24 h) were severely injured, had bilateral femur fracture (p = 0.001) and had higher rate of external fixation, blood transfusion, pulmonary complications and prolonged hospitalization. Non-union proportion was greater in those who had IMN <24 h, whereas a delayed union was greater in IMN done after 24 h (p = 0.5). Those with a nonunion femur fracture were more likely to have bilateral fracture (p = 0.003), frequently had retrograde nailing (p = 0.01), and high-grade femur fracture (AO type C; p = 0.04). CONCLUSION: This study showed that femur fracture is not uncommon (8.9%), which is manifested with the variety of clinical characteristics, depending on the mechanism, management and outcome in our center. Bilateral fracture, retrograde nailing and AO classification type C were the significant risk factors of non-union in patients with diaphyseal fractures. The timing of IMN has an impact on the fracture union; however, it is not a statistically significant difference. Therefore, the treating physicians should consider the potential risk factors for a better outcome by careful selection of treatment in sub-groups of patients.

Trouble in Tiger country: isolated traumatic pancreatic transection - a case report.

Isolated pancreatic transection is a rare surgical condition that occurs more commonly following blunt abdominal trauma. It carries a high degree of morbidity and mortality, and the management remains a source of debate as universally accepted guidelines are not well established owing to the paucity in clinical experience and large series. We presented a case of an isolated pancreatic transection following blunt abdominal trauma. The surgical management of pancreatic transection has evolved over the decades from aggressive approaches to more conservative measures. Given the lack of large series and clinical experience, no universal consensus exists, except for applying damage control surgery and resuscitation principles in critically unstable patients. For transections of the main pancreatic duct, most recommend excision of the distal pancreas. Concerns over the iatrogenic complications of wide excisions, particularly diabetes mellitus, have led to reconsideration and more conservative approaches, but it may fail in some cases.

Home-related falls: An underestimated mechanism of injury.

BACKGROUND: The home is a leading location for falls, but the epidemiology and outcome of falls at home (FH) have not been adequately described. Our aim was to evaluate FH, particularly in the bathroom. MATERIALS AND METHODS: We conducted a retrospective analysis of patients with a history of FH admitted to the Level I trauma center in Qatar. Patients were divided into Group 1: <60 years and Group 2: 60 year or older, and their data were analyzed and compared. RESULTS: A total of 98 patients with FH in the bathroom with a mean age of 51 ± 18 years, mostly males (73.5%) were identified over 3 years. One out of every 50 trauma patients admitted was a victim of a fall in the bathroom. Group 2 had significantly more females and sustained a single-site injury. Group 1 had more involvement of alcohol (P = 0.02) and sustained more multiple injuries (44% vs. 23%; P = 0.02). The mean Injury Severity Score and length of hospital stay was comparable among the two groups. Head, abdomen, and facial injuries were significantly higher in Group 1 whereas lower extremity injuries and mortality were significantly higher in Group 2. CONCLUSION: FH, particularly in the bathroom, is an underrecognized mechanism of injury with a unique dichotomous epidemiology based on age. This needs increased public awareness and primary prevention programs for high-risk populations.

False negative pericardial Focused Assessment with Sonography for Trauma examination following cardiac rupture from blunt thoracic trauma: a case report.

INTRODUCTION: The Focused Assessment with Sonography for Trauma examination is an invaluable tool in the initial assessment of any injured patient. Although highly sensitive and accurate for identifying hemoperitoneum, occasional false negative results do occur in select scenarios. We present a previously unreported case of survival following blunt cardiac rupture with associated negative pericardial window due to a concurrent pericardial wall laceration. CASE PRESENTATION: A healthy 46-year-old white woman presented to our level 1 trauma center with hemodynamic instability following a motor vehicle collision. Although her abdominal Focused Assessment with Sonography for Trauma windows were positive for fluid, her pericardial window was negative. After immediate transfer to the operating room in the setting of persistent instability, a subsequent thoracotomy identified a blunt cardiac rupture that was draining into the ipsilateral pleural space via an adjacent tear in the pericardium. The cardiac injury was controlled with digital pressure, resuscitation completed, and then repaired using standard cardiorrhaphy techniques. Following repair of her injuries (left ventricle, left atrial appendage, and liver), her postoperative course was uneventful. CONCLUSIONS: Evaluation of the pericardial space using Focused Assessment with Sonography for Trauma is an important component in the initial assessment of the severely injured patient. Even in cases of blunt mechanisms however, clinicians must be wary of occasional false negative pericardial ultrasound evaluations secondary to a concomitant pericardial laceration and subsequent decompression of hemorrhage from the cardiac rupture into the ipsilateral pleural space.

External air compression: A rare cause of blunt esophageal injury, managed by a stent.

INTRODUCTION: Blunt esophageal injuries secondary to external air compression of anterior chest and abdomen complicated with esophageal perforation are uncommon events associated with worse outcomes. PRESENTATION OF CASE: We reported a rare case of esophageal perforation following an external air-compression injury along with the relevant review of literatures. The patient presented with chest pain and shortness of breath and was managed with tube thoracostomy, followed by thoracotomy and eventually with temporary endoscopic stenting. DISCUSSION: In such trauma case, the external pressurized air forms a shock wave which usually directed to the hollow viscus. Patients with external air-compression injury presented with chest pain and pneumothorax should be suspected for esophageal perforation. CONCLUSION: High index of suspicion is needed for early diagnosis of esophageal perforation after blunt trauma. Appropriate drainage, antibiotic and temporary endoscopic esophageal stenting may be an optimal approach in selected patients, especially with delayed diagnosis.

Dilemma of blunt bowel injury: what are the factors affecting early diagnosis and outcomes.

Blunt bowel and mesenteric injury (BBMI) is frequently a difficult diagnosis at initial presentation. We aimed to study the predictors for early diagnosis and outcomes in patients with BBMI. Data were collected retrospectively from the database registry between January 2008 and December 2011 in the only Level I trauma unit in Qatar. Patients with BBMI were divided into Group A (surgically treated within 8 hours) and Group B (treated after 8 hours). Data were analyzed and χ2, Student's t test, and multivariate regression analysis were performed appropriately. Among 984 patients admitted with blunt abdominal trauma (BAT), 11 per cent had BBMI with mean age of 35 ± 9.5 years. Polytrauma and isolated bowel injury were identified in 53 and 42 per cent, respectively. Mean Injury Severity Score (ISS) was higher in Group A in comparison to Group B (18 ± 11 vs. 13 ± 8; P = 0.02). Presence of pain and seatbelt sign (P = 0.02) were evident in Group B. Hypotension (P = 0.004) and hypothermia (P = 0.01) were prominent in Group A. The rate of positive Focused Assessment Sonography for Trauma was greater in Group A (P = 0.001). Among operative findings, bowel perforation was more frequent in Group B (P = 0.04), whereas mesenteric full-thickness hematoma was significantly higher in Group A. Pelvic fracture was more frequent finding in Group A (P = 0.005). The overall mortality rate was 15.6 per cent. In patients with BAT, the presence of abdominal pain, hypotension, ISS greater than 16, hypothermia, pelvic fracture, and mesenteric hematoma might help in early diagnosis of BBMI. Moreover, base deficit and mean ISS were independent predictors of mortality. Delayed operative interventions greater than 8 hours increased morbidity rate but had no significant impact on mortality.

Concurrent rib and pelvic fractures as an indicator of solid abdominal organ injury.

OBJECTIVES: To study the association of solid organ injuries (SOIs) in patients with concurrent rib and pelvic fractures. METHODS: Retrospective analysis of prospectively collected data from November 2007 to May 2010. Patients' demographics, mechanism of injury, Injury severity scoring, pelvic fracture, and SOIs were analyzed. Patients with SOIs were compared in rib fractures with and without pelvic fracture. RESULTS: The study included 829 patients (460 with rib fractures ± pelvic fracture and 369 with pelvic fracture alone) with mean age of 35 ± 12.7 years. Motor vehicle crashes (45%) and falls from height (30%) were the most common mechanism of injury. The overall incidence of SOIs in this study was 22% (185/829). Further, 15% of patient with rib fractures had associated pelvic fracture. SOI was predominant in patients with concurrent rib fracture and pelvic fracture compared to ribs or pelvic fractures alone (42% vs. 26% vs. 15%, respectively, p = 0.02). CONCLUSIONS: Concurrent multiple rib fractures and pelvic fracture increases the risk of SOI compared to either group alone. Lower RFs and pelvic fracture had higher association for SOI and could be used as an early indicator of the presence of SOIs.

Rib fracture patterns predict thoracic chest wall and abdominal solid organ injury.

Blunt trauma patients with rib fractures were studied to determine whether the number of rib fractures or their patterns were more predictive of abdominal solid organ injury and/or other thoracic trauma. Rib fractures were characterized as upper zone (ribs 1 to 4), midzone (ribs 5 to 8), and lower zone (ribs 9 to 12). Findings of sternal and scapular fractures, pulmonary contusions, and solid organ injures (liver, spleen, kidney) were characterized by the total number and predominant zone of ribs fractured. There were 296 men and 14 women. There were 38 patients with scapular fracture and 19 patients with sternal fractures. There were 90 patients with 116 solid organ injuries: liver (n = 42), kidney (n = 27), and spleen (n = 47). Lower rib fractures, whether zone-limited or overlapping, were highly predictive of solid organ injury when compared with upper and midzones. Scapular and sternal fractures were more common with upper zone fractures and pulmonary contusions increased with the number of fractured ribs. Multiple rib fractures involving the lower ribs have a high association with solid organ injury, 51 per cent in this series. The increasing number of rib fractures enhanced the likelihood of other chest wall and pulmonary injuries but did not affect the incidence of solid organ injury.
