First rib fractures (FRFs) have historically been a marker for severe trauma and poor outcomes. The aim of this study was to assess whether an association still exists between a fractured first rib and global trauma scores suffered by the patient, examine mortality rate and identify other commonly associated injuries. This study examined patients who presented to the Rockhampton Hospital with a traumatic FRF between the dates of July 2015 to June 2020. Patient demographics, mortality rate and additional injuries sustained by the patients were collected. The Injury Severity Score (ISS) was utilised and calculated for each patient. Analysis was conducted to determine associations between trauma scores and FRFs, mortality rate and other injuries sustained at the time of rib fracture. In total, 545 patients had a rib fracture with 48 patients identified as having an FRF. Median age was 50 years. Thirty-seven (77%) were male. The most common mechanism of FRF was motor vehicle/motorbike accidents (71%). Fifty percent of patients with an observed FRF had the highest global ISS of very severe, with 13% severe, 22% moderate and 15% mild. No patients died from their injuries. Of those with an FRF, 79% experienced fractures other than ribs, 75% had other rib fractures and 52% had chest injuries. A larger than expected proportion of FRFs were not associated with severe trauma scores or high mortality. These findings suggest that patients with an FRF may have a greater chance of surviving their traumatic FRF than previously reported. Clinicians should be aware of the potential for severity and other associated injuries, such as chest wall fractures and thoracic injuries, when treating a patient with a fracture of their first rib

Rib fracture fixation by orthopaedic and cardiothoracic surgeons has become increasingly popular for the treatment of chest injuries in trauma. The literature, though mainly limited to Level II and III evidence, shows favourable results for operative fixation. In this paper we review the literature and discuss the indications for rib fracture fixation, surgical approaches, choice of implants and the future direction for management. With the advent of NICE guidance and new British Orthopaedic Association Standards for Trauma (BOAST) guidelines in production, the management of rib fractures is going to become more and more commonplace

This study aimed to assess the outcomes of patients with complex rib fractures undergoing operative or non-operative management at our center over a six-year time period. Retrospective analysis was performed to identify all patients with complex rib fractures at our center from May 2016 to September 2022. Outcome measures included mechanical ventilation, tracheostomy, pneumonia, and mortality at one year. 388 patients with complex rib fractures were identified. 37 (10%) patients fulfilled criteria for surgical management and underwent rib fracture fixation; 351 patients were managed non-operatively with anaesthetic block or analgesia alone. The fixation group had a significantly higher proportion of patients with flail chest (30 (81%) vs 94 (27%), p<0.001) and were significantly more likely to require ICU admission (30 (81%) vs. 16 (5%), p<0.001) than the non-operative group. At one year follow-up, no significant differences were seen for mortality between these groups (1 (3%) vs. 27 (7%), p=0.276). Of the surgical management group, those that underwent fixation <72 hours post injury were significantly less likely to develop pneumonia than those who were delayed >72 hours (2 (18%) vs 15 (58%), p=0.038), with downward trends noted for ICU length of stay (6 vs 10 days, p=0.140) and duration of mechanical ventilation (5 vs 8 days, p=0.177); no significant differences were seen for tracheostomy (3 vs. 5, p=0.588) or mortality (0 vs 1, p=0.856). Surgical fixation of complex rib fractures improves outcomes in selected patient groups. Early surgical fixation led to reduced rates of pneumonia and may improve other outcome measures

Historically rib fractures have been managed conservatively but over recent years evidence has continued to grow in support of fixation in select cases. Rib fractures can affect patients’ ability to adequately ventilate and increase the morbidity and mortality of patients with multiple injuries. There is increasing evidence that rib fracture fixation in certain patients is of benefit, reducing length of stay both in the Intensive Care Unit (ICU) and overall hospital stay, as well as resulting in a decreased rate of tracheostomy and pneumonia. We commenced rib fracture fixation two years ago as a combined procedure between Trauma Orthopaedics and Cardiothoracic surgery for carefully identified patients. We instituted a multi-disciplinary decision making process involving the Orthopaedic, Cardiothoracic and ICU teams. We present the initial results for these patients. Fourteen patients with a total of 49 ribs were fixed between November 2015 and August 2017. Nine patients were acute and multiply injured, with five patients treated with delayed fixation for ventilation problems following non-union of existing fractures. The average length of stay was 13 days. Follow up is ongoing with a mean follow up of 192 days. There have been no deep infections or acute complications and no incidence of peri-operative pneumothorax in this initial cohort. There have been no deaths, and all of these patients have since been discharged to their own home. The initial outcomes following the introduction of this new procedure to our unit have been encouraging, although the long term results are awaited

High energy chest trauma resulting in flail chest injury is associated with increased rates of patient morbidity. Operative fixation of acute rib fractures is thought to reduce morbidity by reducing pain and improving chest mechanics enabling earlier ventilator weaning. A variety of operative techniques have been described and we report on our unit's experience of acute rib fracture fixation. Over 18 months, 10 patients have undergone acute rib fracture fixation. Outcome measures included; patient demographics, time ventilated pre-operatively, time ventilated post-operatively and time spent on ITU/HDU post operatively. The mean time from presentation to surgery was 5 days (range 2–12 days). The mean time ventilated post operatively was 2 days (range 1–4 days) and the mean number of days spent on ITU/HDU post-operatively was 6 days (range 2–11 days). Our results appear positive in terms of time spent ventilated post-operatively but no conclusion can be drawn as we have no comparable non-operative group. We have however shown, that rib fracture fixation can be carried out successfully and safely in a trauma centre. Further evidence on rib fracture fixation is required from a large, multi-centre randomised controlled trial

Flail chest and multiple rib fractures are common injuries in trauma patients. Several small randomized studies have suggested significant improvements in patient outcomes with surgical fixation, compared to nonoperative management, yet emerging population-level data report some conflicting results. The objectives of this study were to compare the results of surgical fixation and nonoperative management of multiple rib fractures and flail chest injuries and to assess whether effects varied by study design limitations, including risk of confounding by indication. A comprehensive search of electronic databases (Medline, Embase, Web of Science) was performed to identify randomized controlled trials and observational studies. Random effects models were used to evaluate weighted risk ratios (RR) and mean differences (MD). Risk of confounding by indication was assessed for each study (low, medium, and high risk), and this categorization was used to stratify results for clinical outcomes. Publication bias was assessed. Thirty-nine studies, with a total of 19,357 patients met inclusion criteria. Compared to nonoperative treatment, surgical fixation of flail chest and multiple rib fractures was associated with decreased risk of death (overall RR 0.40, 95% confidence interval (CI) 0.28–0.56), pneumonia (overall RR 0.70, 95% CI 0.52–0.93), tracheostomy (overall RR 0.62, 95% CI 0.41–0.93), and chest wall deformity (overall RR 0.16, 95% CI 0.06–0.42). However, many of the observational studies were at risk of confounding by indication, and results varied according to risk of confounding by indication. Differences in ventilator time, intensive care unit length of stay (LOS), hospital LOS, and return to work will be assessed (results pending). Compared to nonoperative treatment, surgical fixation of flail chest and multiple rib fractures is associated with improved clinical outcomes. Discrepancies between some study results may be due to confounding by indication. Additional prospective randomized trials and high-quality observational studies are required to overcome potential threats to validity and to expand on existing evidence around optimal treatment of these injuries

Unstable chest wall injuries have high rates of mortality and morbidity. These injuries can lead to respiratory dysfunction, and are associated with high rates of pneumonia, sepsis, prolonged ICU stays, and increased health care costs. Numerous studies have demonstrated improved outcomes with surgical fixation compared to non-operative treatment. However, an adequately powered multi-centre randomized controlled study using modern fixation techniques has been lacking. We present a multi-centred, prospective, randomized controlled trial comparing surgical fixation of acute, unstable chest wall injuries with the current standard of non-operative management. Patients aged 16–85 with a flail chest (3 or more consecutive, segmental, displaced rib fractures), or severe deformity of the chest wall, were recruited from multiple trauma centers across North America. Exclusion criteria included: severe pulmonary contusion, severe head trauma, randomization>72 hours from injury, inability to perform surgical fixation within 96 hours from injury (in those randomized to surgery), fractures of the floating ribs, or fractures adjacent to the spine not amendable to surgical fixation. Patients were seen in follow-up for one year. The primary outcome was days free from mechanical ventilation in the first 28 days following injury. Secondary outcomes were days in ICU, rates of pneumonia, sepsis, need for tracheostomy, mortality, general health outcomes, pulmonary function testing, and other complications of treatment. A sample size of 206 was required to detect a difference of 2 ventilator-free days between the two groups, using a 2-tailed alpha error of 0.05 and a power of 0.80. A total of 207 patients were recruited from 15 sites across Canada and USA, from 2011–2018. Ninety-nine patients were randomized to non-operative treatment, and 108 were randomized to surgical fixation. Overall, the mean age was 53 years, and 75% of patients were male, with 25% females. The commonest mechanisms of injury were: motor vehicle collisions (34%), falls (20%), motorcycle collisions (14%), and pedestrian injuries (11%). The mean injury severity score (ISS) at admission was 26, and patients had a mean of 10 rib fractures. Eighty-nine percent of patients had pneumothorax, 76% had haemothorax, and 54% had pulmonary contusion. There were no differences between the two groups in terms of demographics. The final results will be available and presented at the COA meeting in Halifax. This is the largest randomized controlled trial to date, comparing surgical fixation to non-operative treatment of unstable chest wall and flail chest injuries. The results of this study will shed light on the best treatment options for patients with such injuries, help understand outcomes, and guide treatment. The final results will be available and presented at the COA meeting in Halifax

Rib fractures (RF) represent the most common bone fracture after blunt trauma, occurring in 10–20% of all trauma patients and leading to concomitant injuries of the inner organs in severe cases. However, a standardized classification system for serial rib fractures (SRF) does still not exist. Basic knowledge about the facture pattern of SRF would help to predict organ damage, support forensic medical examinations, and provide data for in vitro and in silico studies regarding the thoracic stability. The purpose of our study was therefore to identify specific SRF patterns after blunt chest trauma. All SRF cases (≥3 subsequent RF) between mid-2008 and end of 2015 were extracted from the CT database of our University Hospital (n=383). Fractures were assigned to anterior, antero-lateral, lateral, postero-lateral, and posterior location within the transverse plane (36° each) using an angular measuring technique (reliability ±2°). Rib level, fracture type (transverse, oblique, multifragment, infracted), as well as degree of dislocation (none, </≥ rib width) were recorded and each related to the cause of accident. In total, 3747 RF were identified (9.7 per patient, ranging from 3 (n=25) to 33 (n=1)). On average, most RF occurred in crush/burying injuries (15.9, n=13) and pedestrian accidents (12.2, n=14), least in car/truck accidents (8.8, n=76). Altogether, RF gradually increased from rib 1 (n=140) towards rib 5 (n=517) and then decreased towards rib 12 (n=49), showing a bell-shaped distribution. More RF were detected on the left thorax (n=2027) than on the right (n=1720). Overall, most RF were found in the lateral (33%) and postero-lateral (29%) segment. Posterior RF mostly occurred in the lower thorax (63%), whereas anterior (100%), antero-lateral (87%), and lateral (63%) RF mostly appeared in the upper thorax. RF were distributed symmetrically to the sagittal plane, showing a hotspot (up to 98 RF) at rib levels 4 to 7 in the lateral segment and rib level 5 in the antero-lateral segment. In the car/truck accident group, 47% of all RF were in the lateral segment, in case of frontal collision (n=24) even 60%. Fall injuries (n=141) entailed mostly postero-lateral RF (35%). In case of falls >3 m (n=45), 48% more RF were detected on the left thorax compared to the right. CPR related SRF (n=33) showed a distinct fracture pattern, since 70% of all RF were located antero-laterally. Infractions were the most observed fracture type (44%), followed by oblique (25%) and transverse (18%) fractures, while 46% of all RF were dislocated (15% ≥ rib width). SRF show distinct fracture patterns depending on the cause of accident. Additional data should be collected to confirm our results and to establish a SRF classification system

Aims

In the Netherlands, general practitioners (GPs) can request radiographs. After a radiologically diagnosed fracture, patients are immediately referred to the emergency department (ED). Since 2020, the Máxima Medical Centre has implemented a new care pathway for minor trauma patients, referring them immediately to the traumatology outpatient clinic (OC) instead of the ED. We investigated whether this altered care pathway leads to a reduction in healthcare consumption and concomitant costs.

Summary Statement. MCP-1/ CCR2 axis at the early phase plays a pivotal role in the fracture healing. Inflammation plays a pivotal role in fracture healing. Among them, chemokines play key roles in inflammation. Monocyte chemotactic protein-1 (MCP-1), via its receptor C-C chemokine receptor 2 (CCR2), acts as a potent chemoattractant for various cells to promote migration from circulation to inflammation site. Thus, the importance of MCP-1/CCR2 axis in fracture healing has been suggested. However, the involvement of MCP-1/CCR2 axis tofracture site is not fully elucidated. Results. PCR Array: The expression of MCP-1 and MCP-3 had increased on day 2 than 0 or 7 in the rib fracture healing. Immunohistochemistry Staining: To verify the localization of MCP-1 expression, we examined the Wild type (WT)-mouse rib fracture healing. We observed high expression of MCP-1 and MCP-3 at the periosteum and the endosteum on post-fracture day 3. In vivo Antagonist Study: To elucidate whether MCP-1/CCR2 axis is involved during the early phase of fracture healing, we continuously administered RS102895, CCR2 antagonist, before or after rib fracture. Micro-CT analysis showed delayed fracture healing in the before-group compared with both the control and after-group. On day 21, the hard callus volume in the before-group was significantly smaller than that in the control-group. Histological analysis showed that fractures in both the control and the after-groups were healed by day 21. In contrast, less of cartilage in the callus was observed in the before-group on day 7. Gain of Function: To examine the roles of MCP-1 at the periosteum and the endosteum during the fracture healing, we created a segmental bone graft exchanging model. The bone grafts were transplanted from MCP-1. −/−. mice to another MCP-1. −/−. mice (KO-to-KO). Micro-CT analysis showed that KO-to-KO transplantation led to the delay of fracture healing on day 21. Next, we created exchanging-bone graft models between MCP-1. −/−. and WT mice, in which a segmental bone derived from a WT mouse was transplanted into a host MCP-1. −/−. mouse (WT-to-KO). In contrast to KO-to-KO bone graft transplantation, the transplantation of WT-derived graft into host KO mouse resulted in a significant increase of new bone formation on day 21. Histological analysis revealed that marked and localised induction of MCP-1 expression in the periosteum and the endosteum around the WT-derived graft was observed in the host MCP-1. −/−. mouse. Loss of Function: To validate whether MCP-1 is a crucial chemokine for fracture healing, we created WT-to-WT and KO-to-WT bone graft models. When WT-donor graft was transplanted into WT-host, abundant new bone formation was observed around a WT-derived graft on day 21. In contrast, transplantation of KO-derived graft into WT-host resulted in a marked reduction of periosteal bone formation on a donor graft. Discussion. In this study, we demonstrated that MCP-1/ CCR2 axis at the early phase modulates the fracture healing. Furthermore, we showed that MCP-1 in the periosteum and the endosteum promotes the fracture healing in vivo. Thus, these results clearly suggest that MCP-1 in the periosteum and the endosteum at the early inflammatory phase is an essential component for successful fracture healing

Our aim was to investigate the incidence and outcome of chest injuries after blunt trauma in patients admitted in a level I trauma centre over a 6-year period. This is a review of prospectively collected data (1996–2002); part of the (TARN-UK) data. Patients divided in 6 subgroups based on the chest AIS. Univariate analysis identified factors predicting mortality and a backward stepwise logistic regression multivariate analysis determined relationships with outcome. There were 1,164 patients with chest injuries. The mean overall severity of chest injuries was 3.15+/−1.01. The commonest mechanism of injury was RTAs (57.01%). Rib fractures were the most common injuries (395 patients, 34%) associated with lung contusions in 12.9%. Admission GCS was highest in chest-AIS subgroup 2 and was significantly higher in groups 1 and 3. Complications, invasive operations, and investigations were more common with increasing chest-AIS. The ICU-admissions and the mean length-of-stay were similar for chest-AIS1 and 2, but significantly higher for the rest. Half of the AIS1 patients had associated head injuries; the lowest percentage was in subgroup 2 (18.8%). There was a variable correlation of abdominal injury severity with severity of chest injury. There was a significant difference in mortality rates between group 2 and group 1 and -3. The average time to death in those with chest-AIS1 was significantly lower than the average time in those with AIS4 and 5. Patients in the higher AIS groups had both a higher overall ISS and mortality rate. Minimal chest injury severity (AIS1) showed higher ISS and significantly higher mortality compared with chest-AIS2,3. This has been attributed to the fact that the chest is spare as most of the impact during the course of the accident is been absorbed by the head (head injury). This theory also explains the shorter time period of death seen in patients belonging to the chest AIS1 group

Aims

A growing number of fractures progress to delayed or nonunion, causing significant morbidity and socioeconomic impact. Localized delivery of stem cells and subcutaneous parathyroid hormone (PTH) has been shown individually to accelerate bony regeneration. This study aimed to combine the therapies with the aim of upregulating fracture healing.

Fractures and fracture dislocations involving the lower lumbar spine and lumbosacral junction are uncommon. These high velocity injuries are often associated with neurological deficit, incontinence and dural tears. The accepted treatment has been posterior stabilisation with fusion, but loss of reduction has often been reported. We reviewed our experience over the past four years in the management of eight male patients, two of whom sustained injuries in motor vehicle accidents and two in falls from a height. Two patients had L5/S1 traumatic spondylo-listhesis with no neurological deficit. Of the six patients with fracture dislocations of L3/4, four had translation in the sagittal and coronal planes and incomplete neurological deficit. Associated injuries in four patients included an ankle fracture, multiple rib fractures, dislocation of knee and hip, and a fracture dislocation of the midfoot. Following satisfactory reduction, seven patients were treated by posterior spinal fusion (PSF) with instrumentation. One patient had anterior decompression, strut-grafting and posterior instrumentation. Three patients had dural tears. In three patients treated by single segment PSF, reduction was not maintained. The maintenance of alignment was attributed to stable facet joints in one patient, two-segment instrumentation in three, and anterior strut grafting in one. One patient developed postoperative wound sepsis, which settled after repeated debridement and antibiotic treatment. Symptoms of nerve root compression improved in two of the four patients with neurological deficit. Posterior reduction and instrumentation alone did not maintain reduction in these severe injuries. Anterior column support and multisegmental instrumentation may be required where there is marked vertebral body compression and neurological deficit

Aims

The number of convolutional neural networks (CNN) available for fracture detection and classification is rapidly increasing. External validation of a CNN on a temporally separate (separated by time) or geographically separate (separated by location) dataset is crucial to assess generalizability of the CNN before application to clinical practice in other institutions. We aimed to answer the following questions: are current CNNs for fracture recognition externally valid?; which methods are applied for external validation (EV)?; and, what are reported performances of the EV sets compared to the internal validation (IV) sets of these CNNs?

Introduction: Fractured scapula is rare because the scapula is mobile and well protected. We report the first prospective study in the literature of scapular fractures caused by blunt trauma. Patients: 67 consecutive patients (64 males and 3 females, with a mean age of 33 (8–60) years) were included between January 2003 and September 2004. Data regarding the mechanism of injury, associated injuries, the Injury Severity Score (ISS), the location of the scapular fracture, whether it was isolated or involved more than one part of the scapula, and the accuracy of radiographic modality used were analyzed. Results: 50 (75%) fractures were caused by road traffic accidents, 11 by afall from height, 4 from a fall from the same level and 2 by heavy object. 56 patients (84%) sustained associated injuries of which chest injury occurred in 48 (72 %) and was the most frequent. Many patients had more than one substantial chest injury. 30 (45%) patients had lung contusion, 27 rib fracture, 23 haemothorax and 22 pneumothorax. The abbreviated injury score for chest injury for the isolated fractures (n=41) was 2.1 (0–5) and for the combined fracture group (n=26) was 2.4 (NS). Other associated injuries were upper limb fractures in 29 patients, head and facial injuries in 25, 17 had pelvic fractures, lower limb fractures occurred in 16 patients, 15 had spinal fractures and 10 abdominal injuries. No brachial plexus or subclavian artery injury occurred. The mean ISS was 20 for both fracture groups. 41 (61%) of fractures were isolated. Of these, 31 (75%) involved the body of the scapula, 4 acromion, 2 glenoid, 2 coracoid, 1 neck and 1 spine. For the 26 combined fractures, the body was involved in 24 (92%), 13 the neck, 12 spine, 4 glenoid, 4 acromion and 3 coracoid. Plain chest X-ray was done in 63 patients and the scapular fracture was shown in 40 (63%). 42 patients had scapular X-rays and the fracture was seen in 35 (83%). The fracture was shown in all 42 patients that had computer tomography (CT) of the chest. The same was true for the 19 patients who had CT of the scapula. In total, CT was done in 61 (91%) of the 67 patients. Discussion; Scapular fracture has a high rate of associated injuries, mainly to the chest. Lung contusion, haemo- and pneumothorax were very frequent in our series compared with other reports. The liberal use of trauma CT protocols and the prospective nature of the study may explain this finding

Both posterior and anterior surgery have potential for complete scoliosis correction. Significant difference in judging the procedures still persists. Aim. To establish objective advantages and risks of the procedures, basing upon long term results. Method. From 1982–2007, 859 anterior(A) and 388 posterior(P) instrumentations were performed by the same surgeon. Single level thoracotomy used even in double curves. Spinal canal was never opened, rib heads left intact, ribs were fractured at the top of rib hump. Zielke rod was used for correction, and another rod added for aditional correction and stabilisation. Various posterior instrumentations were used. Results. CORRECTION (A)frontal 67-45-16(76%), sagital +6, (P)frontal 66-44-29(56%), sag+3; OP. TIME (A)140(50–300), (P)155(110–350); BLOOD REPL. (A)18%, (P)92%; HOSP STAY (A)10, (P)13; VC (A)-10%, (P)0%; SPORT ACT. (A)3mths, (P)12mths; MAJOR COMPLICATIONS: no deaths, (A)1 aorta rupture, 1 bronchus penetration, 0,7% haematothorax, 0,6% reinstrumentation, 0,7% infections demanding op, (P)2 paraplegia (0,5%), 3.9% infections, 4.9% reinstrumentation. Discussion. (A)required no neuromonitoring, no intensive care unit. Blood replacement was occasionally used only for double curves (11 segm), and in preop. anemia. Most of the complications were preventable. Hospitalisation was longer in (P) group due to wound problems. Pulmonary decrease was found only in curves greater than 100 °. Halo traction improved VC, but both instr. had no influence on further improv. In (A)VC recovered in 6 months. Conclusions. (A) can be performed in less radical and agressive way. Anterior release significantly mobilizes the spine and decreases necessary corrective forces. Infection was more frequent in (P) but consequences were more dramatic in (A). All major complications in (A) were preventable. There is temporary decrease in pulmonary function after (A). We could not find objectives for (A) to have more morbidity than (P). Due to superior results we still prefer (A) in surgery of AIS. Our indications for (P) is VC<40%, age, poor bone quality, surgery in upper thoracic spine
