‘Low-Plane’ Fractures of the Distal Humerus in Elderly Patients with Osteoporosis Show High Postoperative Complication Rates

Background: This study aimed to investigate the fracture patterns and complexity of distal humerus fractures with high-resolution computed tomography (CT) as a function of Dual-Energy X-ray absorptiometry (DXA)-derived bone marrow density (BMD) measurements in an elderly patient cohort. Methods: A retrospective chart review was conducted on patient data collected at a Level I trauma center between January 2007 and January 2022. Inclusion criteria comprised patients aged ≥40 years with a confirmed distal humerus fracture as demonstrated by CT. Additionally, patients were included if they underwent DXA. Patient demographics and detailed information regarding the surgical treatment and trauma mechanism were retrieved from the institutional databank. Fractures were classified as either ‘low-plane’ distal humeral fractures or ‘non-low-plane’ distal humerus fractures. Furthermore, the fracture patterns were classified according to established classification systems. Intra- and postoperative complication and revision rates were analyzed. Results: A total of 41 patients (30 women; mean age 74 ± 13 years) were enrolled. Low-energy trauma was sustained by 68% of the patients. The remaining 32% of the fractures involved medium-energy trauma. A total of 62% of the patients underwent primary osteosynthesis, while 30% of patients were initially treated with an external fixator. ORIF was performed in 89% of cases and, in the majority, double-plate osteosynthesis was used (76%). An olecranon osteotomy was performed in 30% of cases. A total of 5% of cases received total elbow arthroplasty, and 10% of cases were treated conservatively. A total of 61% of patients had osteoporosis, 24% of patients had osteopenia, and 15% of patients had a normal BMD with an overall mean T-score of −2.4. Most of the fractures were complex (including 61% Type C fractures). A total of 66% of cases were considered as ‘low-plane’ fractures. Postoperative complications occurred in 11% of patients (64% of cases among ‘low-plane’ fractures). Revision surgery was required in 20% of cases. Conclusions: The consecutive series of patients showed a high incidence of ‘low-plane’ fractures. However, no statistical significance was found between the BMD and fracture complexity. The very distal ‘low-plane’ fractures showed a high complication rate, which was aggravated by osteoporotic bone conditions. These findings highlight the need for future research with larger patient samples to better understand the relationship between the BMD, fracture complexity, and outcomes in patients with ‘low-plane’ fractures in order to reduce complications and improve clinical outcomes.

Odontoid Fractures: A Review of the Current State of the Art.

Odontoid fractures (OFs) represent up to 15% of all cervical fractures encountered and present most commonly amongst elderly patients, typically in the setting of low energy trauma such as falls. The Anderson and D'Alonzo classification and Roy-Camille subtype description are the most clinically noteworthy descriptions of OFs used. Even though most patients will not present with neurological injury, mechanical instability can occur with type II and type III (Anderson and D'Alonzo) fractures, particularly if the transverse ligament of the atlas is ruptured; however, this is very rare. Conservative treatment is usually employed for type I and type III injuries, and to a varying degree for non-displaced type II injuries. Surgical treatment is typically reserved for type II fractures, patients with neurological injury, and in the setting of other associated fractures or ligamentous injury. Anterior screw fixation is a viable option in the setting of a favorable fracture line orientation in type II fractures, whereas posterior C1-C2 screw fixation is an option for any type II or type III fracture presentation. There is evidence that surgery for type II fractures has higher rates of union and lower mortality than nonoperative treatments. While surgical options have increased over the decades and the management of OF has been optimized by considering fracture subtypes and patient factors, there remains a significant morbidity and mortality associated with OFs. The aging population and changing demographics suggest that there will be an ongoing rise in the incidence of OFs. Therefore, the appropriate management of these cases will be essential for ensuring optimization of health care resources and the quality of life of affected patients.

Prehospital undertriage of older injured patients in western Switzerland: an observational cross-sectional study

BackgroundThe ageing of the population is leading to an increase in the number of traumatic injuries and represents a major challenge for the future. Falls represent the leading cause of Emergency department admission in older people, with injuries ranging from minor to severe multiple injuries. Older injured patients are more likely to be undertriaged than younger patients. The aim of this study was to investigate the extent of undertriage in older patients with particular emphasis on access to trauma centres and resuscitation rooms.MethodsRetrospective observational cross-sectional study based on data prospectively collected from prehospital electronic records including all patients ≥ 18 years for whom an ambulance or helicopter was dispatched between 1 January 2018 and 31 April 2023 due to a trauma. The primary outcome, admission to the resuscitation room of the regional trauma centre with trauma team activation, was assessed by age. Multivariate logistic regression was used to control for known confounders and to test for plausible effect modifiers.ResultsEmergency Medical Services treated 37,906 injured patients. Older patients ≥ 75 years represented 17,719 patients (47%). Admission to trauma centre with trauma team activation was lower in older patients, N = 121 (1%) compared to N = 599 (5%) in younger patients, p < 0.001; adjusted odds ratio: 0.33 (0.24–0.45); p < 0.001. Undertriage increased by twofold with age ≥ 75; OR: 1.81 (1.04–3.15); p value < 0.001. Undertriaged patients were older, more likely to be female, to have low energy trauma and to be located farther from the regional trauma centre.ConclusionOlder injured patients were at increased risk of undertriage and non-trauma team activation admission, especially if they were older, female, had head injury without altered consciousness and greater distance to regional trauma centre.

Sacral U-type Fractures in Patients Older Than 65 years.

The purpose of this study was to determine the degree of disability that geriatric patients with sacral U-type fractures experience. Patients older than 65 years presenting from 2013 to 2019 with a U-type sacral fracture were included. Patient demographics, treatment type, preinjury domicile, preinjury use of assistive devices, and neurologic deficits were recorded. Outcomes included mortality, return to preinjury domicile, and use of assistive devices for mobility. Among 46 patients in the treatment period, ground-level fall was the most common mechanism of injury (60.8%). Thirty-four patients (74%) were treated surgically, most commonly with closed percutaneous fixation (n = 27). Thirteen percent of patients died during the admission. At the final follow-up, 14 (45%) had not returned to their prior domicile and 18 (58%) required more supportive assistive devices. Seventy-three percent of patients who presented delayed required a new gait aid, compared with 47% presenting acutely. Between those presenting with low-energy versus high-energy mechanisms, similar rates of need were observed for new assistive devices (50% low and 73% high) and lack of return to preinjury domicile (40% low, 50% high). Many geriatric patients were disabled by or died after sustaining a sacral U-type fracture, highlighting the morbidity regardless of high-energy or low-energy trauma.

Long-term administration of alendronate sodium caused an atypical femoral shaft fracture in a 36-year-old woman: a case report and literature review.

Long-term bisphosphonate therapy is associated with atypical or insufficiency fractures, particularly in the proximal femur. We observed a case of an atypical femoral shaft fracture in a patient with a long-term history of alendronate therapy. A 36-year-old woman was admitted with a complaint of pain in her right mid-thigh following low-energy trauma. She had been taking alendronate for more than 15 years. X-rays indicated a fracture of the right femoral shaft. The patient was treated with proximal femoral nail antirotation (PFNA) fixation. This case highlights concerns regarding long-term bisphosphonate therapy and its potential complications.

Fragility Fracture of Proximal Tibia in A Wheelchair-Bound 54-Year-Old Female Patient

Sedentary behavior is one of the risk factors of fracture, in which mild activity was found to be inversely associated with hip, vertebral, and total fracture. Other study also found non-linear association of fracture risk with lower and higher physical activity was associated with higher risk of any fracture compared to a mean physical activity. In this study, we reported a 54-year-old wheelchair bound female with fracture on the proximal tibia cause by low-energy trauma. This research underscores the importance of early identification of fracture risk factors, especially in vulnerable populations such as older adults who are wheelchair-bound. Early interventions that include lifestyle changes, increased physical activity, and nutritional management are essential to prevent further fractures and improve bone health. Identifying the risk of fractures on elderly patient may be beneficial for prevention of fractures especially in wheelchair-bound elderly individual.

Simultaneous Bilateral Quadriceps Tendon Rupture in a Patient Undergoing Long-Term Hemodialysis: A Case Report

Bilateral quadriceps tendon ruptures are rare lesions. At.raumatic forms, or those following low-energy trauma, are much rarer and occur on pre-existing lesions. We report a case of bilateral and simultaneous rupture of the quadricipital tendon in a 45-year-old hemodialysis patient with secondary hyperparathyroidism (PTH: 1642 pg /ml). He underwent surgical repair with good evolution after rehabilitation. Spontaneous and simultaneous bilateral ruptures of the quadricipital tendon are exceptional. A pathology that weakens the tendons, such as secondary hyperparathyroidism, which is common in dialysis patients, remains the most common cause.

Contrast-enhanced Ultrasound as a Method of Splenic Injury Assessment

Abstract Splenic injuries are common in abdominal trauma, as the spleen is one of the most often harmed organs. The treatment of splenic injuries underwent major changes during the past decades, shifting from a surgical approach to nonoperative management. This change of the proceedings results from a constantly growing awareness of the spleen’s crucial hematological and immunological function and was possible owing to the advances in radiological techniques. In a setting of high-energy trauma in hemodynamically stable patients, computed tomography (CT) remains the gold standard. Where ultrasonography (US) is of major importance is in cases of unstable patients undergone high-energy trauma or in patients after low-energy trauma. Nevertheless, baseline US’s sensitivity is not sufficient to detect splenic traumatic injuries; hence, a new method was developed involving ultrasound contrast agents (UCAs), called contrast-enhanced ultrasound (CEUS). In a low-energy trauma setting, it facilitates the diagnosis of abdominal lesions with a sensitivity close to that of CT, without the disadvantages of the latter. In addition, CEUS can be used in the follow-up of abdominal traumatic injuries. The fact that CEUS preserves CT’s sensitivity while not carrying the risk of radiation-induced cancer makes it feasible for children and pregnant women. This review aims to discuss the technical aspects of CEUS, the limitations, and possibilities regarding this modality, present the appearance of both a healthy and injured spleen, and compare CEUS’s effectiveness to that of CT through an analysis of retrievable studies.

[Translated article] Anatomical and biomechanical factors of osteoporotic vertebral fracture and the occurrence of cascade fractures

Osteoporosis weakens the structural strength of bone to such an extent that normal daily activity may exceed the capacity of the vertebra to bear this load. Vertebral fracture and deformity is a hallmark of osteoporosis. The detriment of trabecular bone properties alone cannot explain the occurrence of osteoporotic vertebral fracture. The ability of the spine to bear and resist loads depends on the structural capacity of the vertebrae, but also on loading conditions arising from activities of daily living or low-energy trauma. This review describes the mechanical properties of the vertebral bone, the structural load-bearing capacity of the various elements forming the spine, the neuromuscular control of the trunk, as well as the biomechanics of the loads to which the spine is subjected in relation to the presence of osteoporosis and the risk of vertebral fracture. A better understanding of biomechanical factors may help to explain both the high incidence of osteoporotic vertebral fractures and their mechanism of production. Consideration of these issues may be important in the development of prevention and management strategies.

Locking Plate Fixation with Calcium Phosphate Bone Cement Augmentation for Elderly Proximal Humerus Fractures-A Single-Center Experience and Literature Review.

Proximal humerus fractures (PHFs) are among the most common upper-extremity fractures, with a rising incidence linked to the growing elderly population. Treatment options include non-surgical and surgical methods, but the best approach for geriatric PHFs remains debated. Patient selection for treatment must consider clinical and functional outcomes and the potential complications of surgery. Osteoporosis, a key factor in elderly PHFs, meaning those in patients over 65 years old, often results from low-energy trauma and necessitates treatments that enhance bone healing. Bone cement, such as calcium phosphate, is widely used to improve fracture stability and healing. However, the benefits of surgical fixation with bone cement augmentation (BCA) for elderly PHF patients remain controversial. Hence, in this article, we searched databases including MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and Web of Science to analyze the evidence on locking plate fixation (LPF) with BCA for proximal humeral fractures. We aim to provide readers with updates concerning the above issues.

Epidemiological characteristics of traumatic spinal fractures among the elderly in China

The exploration of traumatic spinal fractures (TSFs) within the senior demographic has not been thoroughly scrutinized, particularly with respect to variations across genders, age groups, seasonal periods, and causative factors. This retrospective analysis aimed to dissect differences in the prevalence and characteristics of TSFs among the elderly, factoring in gender, age, seasonal timing, and causation. A retrospective analysis was conducted on the medical and imaging records of 1,415 patients, all aged 60 years or older, who were diagnosed with TSFs from 2013 to 2019. This study categorized the data by gender, age groups (60–70, 70–80, and 80 years or older), seasons, and the cause of injuries, including road traffic crashes (RTCs), falls from low heights (LHF), falls from high heights (HHF), and injuries incurred during everyday activities and agricultural labor (DFI). Male patients exhibited notably higher incidences of RTCs, high-height falls (HHFs), outdoor incidents, comas post-injury, fractures of the lower limbs (LLFs), pelvic fractures (PFs), rib fractures (RFs), intra-thoracic injuries (ITIs), intra-abdominal injuries (IAIs), cervical fractures, and spinal cord injuries (SCIs). With advancing age, there was a marked decline in occurrences of RTCs, HHFs, outdoor incidents, RFs, craniocerebral injuries (CCIs), ITIs, cervical fractures, and SCIs, while the incidences of DFIs, indoor incidents, and thoracic and lumbar (T + L) fractures notably increased. During autumn, LLF occurrences were significantly reduced, whereas the winter season saw an increase in thoracic fractures. Spring time was associated with a higher frequency of lumbar fractures and noncontiguous spinal fractures (NSFs). Significant distinctions were observed in the age distribution, injury circumstances, associated injuries, and SCIs between high-energy impacts (RTCs and HHFs) and low-energy traumas (LHFs and DFIs). In the elderly demographic, TSFs exhibited discernible distinctions based on gender, age, seasonal variations, and etiological factors, impacting the nature and circumstances of injuries, associated traumas, complications, fracture sites, and the occurrence of SCIs.

Comparative efficacy of proximal femoral nail vs dynamic condylar screw in treating unstable intertrochanteric fractures.

Among the most frequent hip fractures are trochanteric fractures, which usually occur from low-energy trauma like minor falls, especially in older people with osteoporotic bones. To evaluate the treatment efficacy of dynamic condylar screws (DCS) and proximal femoral nails (PFN) for unstable intertrochanteric fractures. To find pertinent randomized controlled trials and retrospective observational studies comparing PFN with DCS for the management of unstable femoral intertrochanteric fractures, a thorough search was carried out. For research studies published between January 1996 and April 2024, PubMed, EMBASE, Scopus, Web of Science, Cochrane Library, and Google Scholar were all searched. The complete texts of the papers were retrieved, vetted, and independently examined by two investigators. Disputes were settled by consensus, and any disagreements that persisted were arbitrated by a third author. This study included six articles, comprising a total of 173 patients. Compared to the DCS, the PFN had a shorter operation time [mean difference (MD): -41.7 min, 95% confidence interval (95%CI): -63.04 to -20.35, P = 0.0001], higher success rates with closed reduction techniques [risk ratio (RR): 34.05, 95%CI: 11.12-104.31, P < 0.00001], and required less intraoperative blood transfusion (MD: -1.4 units, 95%CI: -1.80 to -1.00, P < 0.00001). Additionally, the PFN showed shorter fracture union time (MD: -6.92 wk, 95%CI: -10.27 to -3.57, P < 0.0001) and a lower incidence of reoperation (RR: 0.37, 95%CI: 0.17-0.82, P = 0.01). However, there was no discernible variation regarding hospital stay, implant-related complications, and infections. Compared to DCS, PFN offers shorter operative times, reduces the blood transfusions requirements, achieves higher closed reduction success, enables faster fracture healing, and lowers reoperation incidence.

Intraoperative computerised tomography scan for percutaneous fixation of the pelvis: a retrospective case series

PurposeFractures and dislocations of the pelvic ring are complex injuries that when treating require meticulous attention to detail and often specialized technical skill. These injuries can be the result of high-energy trauma, particularly in younger patients, or low energy trauma more often found in the elderly. Regardless of mechanism, these injuries lie on a spectrum of severity and can be treated conservatively or surgically. Percutaneous fixation under fluoroscopic guidance is the preferred standard technique when treating these fractures. This technique can be challenging for a variety of reasons including patient characteristics, intra-operative image quality, fracture morphology, among others.MethodsThis retrospective study evaluated the use of intra-operative computed tomography (CT) using an O-arm imaging system for critical evaluation of fluoroscopic-guided screw placement in twenty-three patients. We retrospectively reviewed all cases of patients who were treated by three fellowship-trained orthopaedic traumatologists during a one-year span. Patients undergoing percutaneous pelvis fixation using both standard fluoroscopy and intraoperative CT with the Medtronic O-arm® (Minneapolis, MN) imaging system. Additionally, procedures performed included open reduction internal fixation (ORIF) of the pelvic ring, acetabulum, and associated extremity fractures.ResultsTwenty-three patients were included in this study. On average, the use of intraoperative CT added 24.4 min in operative time. Five patients (21.7%) required implant adjustment after O-arm spin. Fourteen patients underwent additional post-operative CT. No secondary revision surgeries were attempted after any post-operative CT.ConclusionsOur study suggests that intra-operative CT scan, compared to post-operative CT scan, can be utilized to prevent take-back surgery for misplaced implants and allow for adjustment in real-time.

Management of Femoral and Tibial Shaft Fractures in Chronic Spinal Cord Injury Patients.

To compare outcomes and complications between non-operative and operative management of femur and tibia fractures in patients with paraplegia or quadriplegia from chronic spinal cord injury (SCI). Design: Retrospective cohort study. Three Level-1 Trauma centers. All adult patients with paraplegia or quadriplegia due to a chronic SCI with operative or nonoperative treatment of a femoral or tibial shaft fracture from 01/01/2009 through 12/31/2019 were included. Outcomes collected included range of motion, pain, return to baseline activity, extent of malunion and treatment complications (infection, pressure ulcers, nonunion, DVT/PE, stroke, amputation, death). Comparison between operative and nonoperative treatment were made for each outcome. Fifty-nine patients with acute lower extremity fracture in the setting of chronic SCI fulfilled inclusion criteria with a median age of 46 years in the operative group and 47 years in the non-operative group. Twelve patients (70.6%) in the nonoperative group were male with 32 (76.2%) male patients in the operative group. Forty-six patients (78%) presented as low energy trauma. Differences were seen between operative and non-operative management for pressure ulcers (19% vs 52.9%, p=0.009) and mean VAS pain score at first follow-up (1.19 vs 3.3, p=0.03). No difference was seen for rates of infection, nonunion, DVT/PE, stroke, amputation, death, return to baseline activity, and range of motion. Tibial and femoral shaft fractures commonly resulted from low energy mechanisms in patients with chronic SCI. Operative treatment seemed to decrease morbidity in these patients via lowered rates of pressure ulcers and decreased pain compared to non-operative management. Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Analysis of risk factors affecting postoperative neurological recovery in patients with cervical spine fracture in ankylosing spondylitis.

Ankylosing spondylitis (AS) is a chronic progressive inflammatory disease that mainly affects the spine and involves the sacroiliac and peripheral joints. Low-energy trauma can often lead to spinal fractures and spinal cord injuries (SCIs), the treatment of AS is challenging. The prognosis of neurological function in patients with AS cervical fracture and SCI is a major problem that must sought clinician attention on urgent basis. A total of 106 patients with AS cervical fractures who underwent surgical treatment at Shanghai Changzheng Hospital between August 2009 and 2021 were included in this study. All the patients were divided into 2 groups (improved group and the control group) based on their neurological function improvement at 1 year mark after the surgery. The baseline characteristics, perioperative factors, and procedural outcomes of all the patients including injury type, AS drug treatment, the injured segment, ossified anterior longitudinal ligament injury, spinal hypersignal, decompression time window, operation duration, blood loss, preoperative and postoperative American Spinal Injury Association (ASIA) score were recorded and analyzed. Among the 106 patients, 79 demonstrated improved neurological function at 1 year mark after the surgery. Binary univariate logistic regression analysis revealed significant differences in injury type (P = .018), ossified anterior longitudinal ligament injury (P = .01), operation duration (P = .002), spinal hypersignal (P = .001), preoperative ASIA score (P < .001), and prior AS drug treatment (P = .012). No significant differences were observed in the other variables (P > .05). Binary multivariate logistic regression analysis identified spinal hypersignal (OR = 37.185, P = .028), preoperative ASIA score (OR = 0.16, P = .012) and previous AS drug treatment (OR = 0.296, P = .049) as factors associated with postoperative neurological function improvement. The preoperative ASIA score and previous drug treatment of AS were identified as protective factors affecting the improvement of neurological functions in patients with AS cervical fracture after surgery. Preoperative T2-weighted spinal hypersignal was identified as an independent risk factor affecting the improvement of neurological function recovery in patients with AS cervical fracture after the surgery.

2223 Older patients admitted with a fragility fracture—a review of discharge summary documentation in accordance with HIQA national

Abstract Background Fragility fractures, defined as fractures resulting from low energy trauma (1), are consistent with a diagnosis of osteoporosis. When a patient is discharged from hospital, guidelines recommend principal and additional diagnoses, relevant co-morbidities contributing to primary diagnosis, medications and relevant investigations are recorded (2). Methods This audit reviewed discharge summaries of all patients discharged from a rehabilitation unit over two months, in accordance with the Health Information and Quality Authority’s (HIQA) National Standard for Patient Discharge Summary Information (2). Patients with fragility fractures were identified through medical record review. Principal and additional diagnoses were reviewed, with cause and mechanism of falls considered relevant co-morbidities. Discharge prescriptions for anti-resorptive medications were noted. Dual-energy x-ray absorptiometry (DXA) was recorded as a relevant investigation (3). Results 33 discharge summaries met inclusion criteria. 12 patients were admitted with fragility fractures with a mean age of 81 years (69–90). 83.3% (n = 10) were female. Osteoporosis was mentioned in 50% (n = 6) of discharge summaries of patients with fragility fractures. On review of relevant co-morbidities, likely cause of the fall was documented in 58.3% (n = 7) and mechanism in 75.0% (n = 9). Bone protection was planned in 83.3% (n = 10). Plan for DXA was documented in 8.3% (n = 1). Conclusion This audit demonstrates suboptimal communication between hospital and community teams, despite chronic disease being predominantly managed in the community. In Europe, Ireland has one of the largest disease burdens relating to osteoporosis and the largest increase predicted in the next ten years (4). It is of utmost importance we improve communication to minimise disease burden.

Pelvic ring fracture in the older adults after minor pelvic trauma – is it an innocent injury?

ObjectiveThis study aimed to evaluate the prevalence of severe hemorrhage as a potentially life-threatening complication in elderly patients with isolated, low-energy pelvic ring fractures, which may be more common than previously described. Patients and methodsA retrospective cohort study was conducted at an academic level 1 trauma center, including 579 patients aged over 65 who suffered from isolated low-energy pelvic fractures between 2006 and 2020. Pelvic computer tomography (CT) scans, with or without contrast, were performed and reviewed for patients with suspected posterior ring injury or bleeding. Patients without CT scans were excluded from the study. ResultsAmong the 123 patients with isolated pubic rami fractures, 30 (24.4 %) had bleeding with a significant hemoglobin drop (>2 g%). 21(70 %) patients of these had posterior pelvic ring involvement as compared to 45 who did not bleed (51 %, p = 0.07). There was a significantly larger proportion of patient who received anticoagulant therapy (ACT) with posterior ring injury among the bleeding group (20 % vs 3.2 % p < 0.01). Treatment included blood transfusion (19/123, 15.5 %), and arterial angiographic embolization (5/123, 4 %). No complications related to angio-embolization were observed, and all patients survived the initial 90-day period. No other source of bleeding was identified in any of these patients. ConclusionSevere pelvic hemorrhage in the older adults due to a minor pelvic injury after a low-energy trauma is not an uncommon complication, especially with combination of ACT and posterior pelvic ring fracture. This indicates that these injuries more challenging than previously believed. Geriatric pelvic ring injuries should be monitored carefully with serial blood counts, and low threshold for imaging including contrast enhanced CT scans and angiography.

Does regional implementation of a clinical pathway for older adult patients with pelvic fragility fractures after low-energy trauma improve patient outcomes (PELVIC): a multicentre, stepped-wedge, randomised controlled trial

IntroductionPatients with pelvic fragility fractures suffer from high morbidity and mortality rates. Despite the high incidence, there is currently no regional or nationwide treatment protocol which results in a wide...

Severe Thoracic Trauma Indications and Contraindications for Non-operative and Operative Treatment Strategies

Severe thoracic trauma can occur as a penetrating or blunt mono-injury or as part of a polytrauma. Almost half of all severely injured patients documented in the TraumaRegister DGU were diagnosed with severe chest trauma, defined according to the Abbreviated Injury Scale (AIS) as ≥3. In our own collective, the proportion was even higher with 60%. Emergency surgical treatment with a thoracotomy within the Trauma Resuscitation Unit or within the first hour of admission is an extremely rare intervention in Germany, accounting for 0.9% of severe thoracic injuries. The management of complex polytraumas and extensive pathophysiological reactions to the trauma, as well as knowledge about the development of secondary damage have led to the conclusion that minimally invasive procedures such as video-assisted thoracoscopy (VATS) or inserting a chest drain can resolve most severe thoracic injuries. At <4%, penetrating injuries to the thorax are a rarity. Among blunt thoracic injuries, >6% show an unstable thoracic wall that requires surgical reconstruction. The demographic development in Germany leads to a shift in injury pattern. Low-energy trauma results have lower incidence than higher-grade chest wall injuries with penetrating rib fractures in the pleura, lungs, peri-/myocardium and diaphragm. Sometimes this results in instability of the chest wall with severe restriction of respiratory mechanics, which leads to fulminant pneumonia and even ARDS (Acute Respiratory Distress Syndrome). With this background, surgical chest wall reconstruction has become increasingly important over the past decade. Together with the underlying strong evidence, the assessment of the extend and severity of the trauma and the degree of respiratory impairment are the basis for a structured decision on a non-surgical or surgical-reconstructive strategy, as well as the timing, type and extent of surgery. Early surgery within 72 hours can reduce morbidity (pneumonia rate, duration of intensive care and ventilation) and mortality. In the following article, evidence-based algorithms for surgical and non-operative strategies are discussed in the context on the management of severe thoracic injuries. Thus, a selective literature search was carried out for the leading publications on indications, treatment strategy and therapy recommendations for severe thoracic injury, chest wall reconstruction.

Lisfranc injuries

Lisfranc injuries are rare but severe injuries of the foot. They range from ligament sprain to complex fracture dislocations. Etiologically, adistinction is made between indirect and direct force and between high-energy and low-energy trauma. Inadequate diagnostics (injuries overlooked or misinterpreted) can lead to painful posttraumatic osteoarthritis, chronic instability and deformity of the foot. Afracture, malalignment and unclear findings in conventional radiological diagnostics necessitate computed tomography imaging including 3D reconstruction. Lisfranc injuries are often associated with accompanying pathologies of the foot that also need to be addressed. Only stable non-displaced fractures can be treated conservatively. Depending on the injury pattern, surgical treatment is performed percutaneously, minimally invasive or open. The prognosis following Lisfranc injury is determined by the severity of damage and the quality of reconstruction.
