Background: Surgical stabilization of rib fractures (SSRF) has been demonstrated to improve early clinical outcomes. Tube thoracostomy (TT) is commonly performed with SSRF, however there is a paucity of data regarding when removal of TT following SSRF should occur. This study aimed to compare patients undergoing thoracic reinterventions (reintubation, reinsertion of TT/pigtail, or video-assisted thoracic surgery) to those not following SSRF+TT, hypothesizing increased TT output prior to removal would be associated with thoracic reintervention.

Methods: We performed a single center retrospective (2018-2023) analysis of blunt trauma patients ≥ 18 years-old undergoing SSRF+TT. The primary outcome was thoracic reinterventions. Patients undergoing thoracic reintervention ((+)thoracic reinterventions) after TT removal were compared to those who did not ((-)thoracic reintervention). Secondary outcomes included TT duration and outputs prior to removal.

Results: From 133 blunt trauma patients undergoing SSRF+TT, 23 (17.3 %) required thoracic reinterventions. Both groups were of comparable age. The (+)thoracic reintervention group had an increased injury severity score (median: 29 vs. 17, p = 0.035) and TT duration (median: 4 vs. 3 days, p < 0.001) following SSRF. However, there were no differences in median TT outputs between both cohorts post-SSRF day 1 (165 mL vs. 160 mL, p = 0.88) as well as within 24 h (60 mL vs. 70 mL, p = 0.93) prior to TT removal.

Conclusion: This study demonstrated over 17 % of SSRF+TT patients required a thoracic reintervention. There was no association between thoracic reintervention and the TT output prior to removal. Future studies are needed to confirm these findings, which suggest no absolute threshold for TT output should be utilized regarding when to pull TT following SSRF.

Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) serves as a bridging intervention for subsequent definitive haemorrhagic control. This study compared the clinical outcomes of REBOA and resuscitative thoracotomy (RT) in patients with bleeding below the diaphragm.

Materials and methods: This retrospective cohort study included adult trauma patients who presented to the Trauma Quality Improvement Program between 2020 and 2021 and who underwent either REBOA or RT in the emergency department (ED). Patients with severe head and chest injuries, characterised by an Abbreviated Injury Scale (AIS) score greater than 3, were excluded. The clinical data of patients treated with REBOA and those treated with RT were compared, and multivariable logistic regression (MLR) was employed to identify prognostic factors associated with mortality.

Results: A total of 346 patients were enrolled: 138 (39.9 %) received REBOA, and 208 (60.1 %) received RT at the ED. Patients in the RT group underwent ED cardiopulmonary resuscitation (CPR) more frequently (58.2 % vs. 23.2 %; p < 0.001) and had a higher mortality rate (87.0 % vs. 45.7 %; p < 0.001). Patients who died had lower Glasgow Coma Scale scores (6 [4.5] vs. 11 [4.9]; p < 0.001), underwent more ED CPR (58.6 % vs. 9.8 %; p < 0.001), and received RT more frequently (74.2 % vs. 26.5 %, p < 0.001). The MLR revealed that the major prognostic factors for mortality were systolic blood pressure (odds ratio [OR] 0.988, 95 % confidence interval [CI] 0.978-0.998; p = 0.014), ED CPR (OR 11.111, 95 % CI 4.667-26.452; p < 0.001), abdominal injuries with an AIS score ≥ 4 (OR 4.694, 95 % CI 1.921-11.467; p = 0.001) and RT (OR 5.693, 95 % CI 2.690-12.050; p < 0.001).

Conclusions: In cases of blunt trauma, prompt identification of the bleeding source is crucial. For patients with bleeding below the diaphragm, REBOA led to higher survival rates than did RT. However, it is important to consider the limitations of the database and the necessary exclusions from our analysis.

Background: Falls are a leading cause of morbidity and mortality among older adults in the United States. Current fall prevention interventions rely on provider referral or enrollment during inpatient admissions and require engagement and independence of the patient. Community emergency medical services (CEMS) are a unique opportunity to rapidly identify older adults at risk for falls and provide proactive fall prevention interventions in the home. We describe the demographics and treatment characteristics of the older adult population most likely to benefit from these interventions.

Materials and methods: We linked 2019 Healthcare Cost and Utilization Project Massachusetts State Emergency Department (ED) and State Inpatient Databases with American Hospital Association survey data to query ED encounters and inpatient admissions for adults age ≥55 with ED encounters for fall-related injury between July 1, 2019 and December 31, 2019. Univariable descriptive statistics assessed participant characteristics and bivariable tests of significance compared diagnoses, disposition, and hospital characteristics between older adults with and without an EMS encounter in the six months prior to the presenting fall.

Results: Of 66,027 older adults who presented with a fall to a Massachusetts ED in July-December 2019, 7,942 (11%) had a prior encounter with EMS in the preceding six months, most of which included an injury diagnosis (99%). Compared to older adults without previous EMS encounters, those with previous EMS encounters were more often in poorer health (17% vs. 10% with multiple or complex comorbidities, p < 0.001) and of lower socioeconomic status (12% vs. 8% in lowest neighborhood income quartile, p < 0.001; 10% vs. 6% enrolled in Medicaid, p < 0.001) compared to those without a prior EMS encounter.

Conclusions: A significant proportion of older adults presenting to the ED with fall related injury have encounters with EMS in the preceding months. These participants are predisposed to poorer health and economic outcomes worsened by their fall and thus demonstrate a population that would benefit from CEMS fall prevention programs.

Background: Occupational injuries impose a substantial global burden, affecting millions of workers annually, which demands urgent attention to enhance workplace safety and health standards. We aimed to outline the frequency, patterns of injury, and clinical characteristics of patients injured by high-rotation cutting tools (grinders) and to pinpoint the neurovascular (nerves and blood vessels) injuries.

Methods: A retrospective study was conducted and included all adult patients hospitalized because of grinder-related injuries at the only level I Trauma Center in the country. The characteristics of patients, mechanism of injury, management and outcomes were analyzed based on the anatomical location of injuries.

Results: 127 patients were hospitalized with grinder-related injuries over ten years. The incidence of GRIs showed an increasing trend over the years. All patients were males with a mean (SD) age of 34.9 (9.8) years. The majority were general laborers (66.1 %), injured by portable grinders (86.6 %), and direct blade contact (64.6 %). The median Injury Severity Score (ISS) was 5.0(IQR 4.0-9.0), and the median Glasgow Coma Scale (GCS) at ED was 15 (3-15). The most frequently injured part was the upper extremity (36.2 %), followed by the lower extremity (33.9 %) and the face (27.6 %). One-third of cases had vascular injuries, and 23.6 % had nerve injuries. Suturing was done for all patients; repairs and debridements were performed in 62 % and 58 % of cases, respectively, and 21 % required vascular surgery. Amputations were required in 9.4 % of cases. Thirty patients had nerve injuries involving the median (11 %) and radial (9.4 %) nerves. Among patients who had neurovascular injuries, 30 % (12/40) experienced complications during the hospital stay, while 60 % (24/40) ended up with physical disabilities.

Conclusion: Individuals affected by power-tool accidents were predominantly young males, mainly general laborers, with a significant proportion being expatriates. The trend of grinder-related injuries increases over time, with portable grinders being a primary source of injuries due to direct contact with the blade. The anatomical injuries mainly include fractures of the upper and lower extremities. Further studies are warranted to understand the cultural aspects and training requirements of workers handling power tools, aiming to achieve sustainable injury prevention effectively.

Background: Physiological criteria are used to assess the potential severity of injury in the early phase of a trauma patient's care trajectory. Few studies have described the extent of abnormality in vital signs and different combinations of these at a national level. Aim of the study was to identify physiologic abnormalities in trauma patients and describe different combinations of abnormalities and changes between the pre-hospital and emergency department (ED) settings.

Method: Norwegian Trauma Registry (NTR) data between 01.01.15 - 31.12.18, where evaluated on the prevalence and characteristics of abnormal physiologic variables. Primary outcome were rates of hypoventilation (respiratory rate [RR] < 10 breaths per min), hyperventilation (RR > 29 breaths per min), hypotension (systolic blood pressure [SBP] < 90 mmHg), and reduced level of consciousness (Glasgow Coma Scale [GCS] < 13).

Results: A total of 24,482 patients were included. Documented values for RR, SBP and GCS were 77.6%, 78.5% and 81.9% in the pre-hospital phase, and the corresponding percentages in the ED were 95.5%, 99.2% and 98.6%, respectively. In the pre-hospital phase, 3,615 (14.8%) patients had at least one abnormal vital sign, whereas the corresponding numbers in the ED, were 3,616 (14.8%) patients. The most frequent combination was low GCS and hyperventilation. A worsened RTS-score from pre-hospital phase to the ED was observed for RR, SBP and GCS in 3.9%, 1.2% and 1.9% of incidents, respectively. Overall 30-day mortality was 3.1% (n=752). Of these, 60.8% had abnormal vital signs, with decreased GCS as the most prevalent (61.3%).

Conclusion: Most trauma patients had normal vital signs. According to the RTS-score, there were few deteriorations in RR, SBP and GCS between pre-hospital phase and the ED. The most frequent abnormality was low GCS, with a higher proportion in those who died within 30 days.

Background: Recurrent pneumothorax (rPTX) is a common complication following thoracostomy tube (TT) removal in chest trauma patients. While chest X-ray (CXR) is most commonly used to detect a rPTX, bedside ultraportable ultrasound (UPUS) is a feasible, low cost, and radiation free alternative. No consensus exists with regards to the optimal timing of diagnostic imaging to assess for rPTX post-TT removal. Accordingly, we sought to identify an ideal UPUS timing to detect a rPTX METHODS: We conducted a single center prospective study of adult (≥18years) patients admitted with a chest trauma. UPUS examinations were performed using the Butterfly iQ⁺™ ultrasound. Three intercostal spaces (ICS) were evaluated (2nd through 4th). Post-TT UPUS examinations were performed at different timepoints following tube removal (1-6 h). A rPTX on UPUS was defined as the absence of lung-sliding in one or more intercostal spaces, and was considered a clinically concerning rPTX if lung-sliding was absent in ≥2 ICS. UPUS findings were compared to CXR.

Results: Ninety-two patients (97 hemi-thoraces) were included in the analysis. A total of 58 patients had a post-TT removal rPTX of which 11 were either clinically concerning or expanding. Comparing UPUS findings to CXR, the 3-hour post-TT removal ultrasound examinations were associated with the highest sensitivity. By hour 4, no rPTX showed expansion in size. Three patients required an intervention for a clinically concerning rPTX, all of whom were detected on UPUS 3-hour post-TT removal.

Conclusion: Bedside UPUS performed at 3-hour post-TT removal has the highest sensitivity in detecting clinically concerning rPTX. Size of rPTX appears to stabilize by hour 4. In the absence of clinical symptoms, repeat imaging or observation of non-significant rPTX beyond 4 h may not provide added clinical benefit.

Level of evidence: Level II, Diagnostic Tests or Criteria.

Introduction: The Pain, Inspiratory effort, Cough score (PIC) has been developed and widely adopted to guide clinical prognostication for patients with chest wall injury. To date, the efficacy, accuracy, and safety of a PIC based triage system has not been validated. Therefore, this study sought to evaluate the use of a modified-PIC score to triage and down-grade trauma patients with chest wall injury at a single institution.

Methods: A retrospective study was conducted at a large, Level I Trauma Center on patients with chest wall injuries admitted between 1/1/2018-10/31/20,222. On 12/1/2020, our institution implemented a modified-PIC triage tool including the PIC score, age, and severity of chest wall injury. The Pre-PIC (1/1/2018-11/20/2020) and Post-PIC (1/1/2021-10/31/2022) groups were composed based on admission date and outcomes between the two were compared.

Results: 2,627 patients comprised the Pre-PIC group and 2,212 patients comprised Post-PIC. The groups didn't differ significantly in demographics or mechanisms of injury except for COVID status. Post-intervention, a greater proportion of patients were triaged to the intermediate care unit instead of the ICU or floor. There were no significant differences in hospital length of stay (LOS), ventilator days, unplanned ICU admission, or mortality in Pre-PIC vs Post-PIC. ICU LOS, rates of ARDS, and cardiac arrest with return of spontaneous circulation (ROSC) were significantly lower in Post-PIC. Multivariable models demonstrated significantly lower ARDS rates and ICU free days. ICU LOS trended towards significance as well.

Conclusions: This is the largest study, to date, evaluating the impact of a modified-PIC triage system on clinical outcomes. The results suggest a modified-PIC triage system may lead to decreased ICU days, ARDS rates, and rates of cardiac arrest w/ ROSC, potentially improving hospital resource allocation. Further prospective and multi-center studies are needed to validate our understanding on the impact of a chest wall scoring system on triage and outcomes.

Background: Fracture healing is a complex biological process that begins soon after a fracture has occurred. Whereas the role of vitamin D status on the maintenance of bone health is well established, the clinical effects of vitamin D deficiency in the healing of distal humeral fractures are less well explored. This study examines the role of vitamin D serum levels in distal humeral fractures (C2, C3) managed with open reduction and double plate fixation, by comparing its concentration in patients with or without radiographic signs of fracture healing and in control subjects. Our hypothesis is that 6 months from treatment vitamin D levels will be different between the groups of patients.

Material and methods: We measured the vitamin D serum level in a cohort of consecutive adult patients aged 30 to 60 years. They included a group of subjects without fractures who were admitted to our clinic in the 6 months preceding the study (controls) and two groups of patients with humeral fractures who at 6-month follow-up showed or failed to show radiological signs of fracture healing.

Results: The mean vitamin D concentration was 23.03 μg/L (±5.8) in the group with radiographic signs of fracture healing, 9.30 μg/L (±2.60) in the group with radiographic signs of delayed union and 26.15 μg/L (±11.76 μg/L) in the control group. Significantly different (p < 0.05) concentrations were measured between the fracture groups, between the group with radiographic signs of fracture healing and the control group and between the group with radiographic signs of delayed union and the control group.

Discussion: Vitamin D is primarily involved in the stages of hard callus formation and remodelling. It also has several functions that affect the early stages of fracture healing. Vitamin D influences the cellular process of bone healing, although the underlying mechanism is still partly unclear. It would be useful to determine the vitamin D status of fracture patients at admission and to start supplementation, with periodic checks, to foster the consolidation phase. Although vitamin D is clearly not the only factor influencing the consolidation of a surgically treated distal humerus fracture, its concentration can easily be determined and managed. Our data suggest that vitamin D levels should be determined at admission and that fracture patients with low concentrations should be started on vitamin D supplementation.

Introduction: The choice between hemiarthroplasty (HA) and total hip arthroplasty (THA) for displaced femoral neck fractures remains debated. There is increasing use in dual mobility cup total hip arthroplasty (DMC-THA) to prevent dislocations in these high-risk patients. Aim of this study is to retrospectively analyze patients treated in a single Center for femoral neck fracture comparing HA and DMC-THA in terms of: functional outcome, rate of complications and mortality.

Material and methods: Between 2020 and 2022, 162 patients were included, 39 male and 123 female, with a mean age of 76 years old. HA were implanted in 82 cases and DMC-THA in 80 cases. INCLUSION CRITERIA WERE: age < 85 years old, American Society of Anesthesiologists (ASA) score below 3, minimum follow-up of 6 months. Overall, 124/162 of patients (77%) were surgically treated within 48 h from admission.

Results: The mean age for DMC-THA group was 74 years old and 78 years old for HA group. The overall mean surgical time was significantly higher in the DMC-THA group (P < 0.001). Mean hemoglobin (Hb) loss was 1.64 g/dl in the HA group and 1.72 g/dl in the DMC-THA group with no differences between the two groups (P = 0.573). There is no difference in survival of patients between the two groups (P = 0.7704). In the HA group, the mean one-month post-operative VAS score was 2.1, while in the DMC-THA group was 0.9. The Harris hip score was significantly better in DMC-THA group (P = 0.035) Dislocation never occured in the overall series. Infection occurred only in one patient with DMC-THA and was treated with debridement. Periprosthetic fracture occurred in 2 cases of DMC-THA both within 1 month from the first surgery; one was treated with revision femoral stem and the second one with fixation.

Conclusions: DMC-THA offer better functional results than HA in elderly patients with femur neck fractures. The mean surgical time was longer in DMC-THA but this did not influence blood loss, time of discharge or one-year mortality. In our series dislocation never occurred in both groups.

Introduction: Radial nerve injury following humeral fracture is the most common peripheral nerve injury associated with long bone fractures. The purpose of this study is to analyse our treatment protocols and long-term outcomes of humeral fractures associated with radial nerve injury which were surgically treated at the I.R.C.C.S. Orthopaedic Institute Galeazzi (Milan, Italy).

Materials and methods: The study was designed to evaluate retrospectively 30 patients, 15 men and 15 women, affected by humeral fracture associated with radial nerve palsy, treated at Orthopaedic Institute Galeazzi (Milan, Italy) from 1st January 2012 to 31st December 2022. Radial nerve injury was diagnosed based on the clinical evaluations of the neurological deficit. The cases were analyzed for any documented sensory impairment, wrist extensor weakness and/or finger weakness, with or without a "drop-hand" posture described in the patient's medical record at admission or throughout the hospital stay. Patients with pathological humeral shaft fractures were excluded. All patients, accounted for the study, were operated under general anaesthesia, and no peripheral nerve block was performed.

Results: The treatment of this clinical condition represents a challenge for orthopaedic surgeons. Most patients (86.7%, 26 patients) experienced total recovery of the radial nerve function during the follow-up period, whereas only 4 patients achieved a partial nerve function recovery, with lingering weakness when extending the fingers.

Conclusions: The chronic outcomes arising from surgical treatment of the humeral fracture with related radial nerve injury can lead to impairment sequelae of greater clinical-functional significance, with possible medico-legal implications. Radial nerve injury constitutes one of the most common complications arising from humeral fracture. The course of the nerve and its close relationship with the humerus are likely to entail a high risk of injury with shaft fractures. A treatment algorithm should be recommended for the management of radial nerve injury associated with humeral shaft fracture.
