A rare case report: compartment syndrome after brachiocephalic arteriovenous fistula formation in a hemodialysis patient

Introduction: Acute compartment syndrome is a condition in which increased pressure in the tight fascia space reduces capillary perfusion below the level required for tissue viability. Very few cases of acute compartment syndrome associated with dialysis have been reported. It can lead to severe damage to the tissues of the arm. Case Illustration: A 47-year-old woman with end-stage renal failure presented to the emergency room with swelling and pain in the right upper extremity and has lasted for a day. Three days before admission, the patient underwent right brachiocephalic arteriovenous (AV) fistula surgery. Physical Examination showed a blackish bruise at the fossa cubiti, radial and ulnar artery were not palpable, but there is trill at AV fistula. Decreased motoric strength, reduced hand sensation and decreased capillary return in fingers. Oxygen blood saturation of the right fingers could not be read. Diagnosis of acute compartment syndrome was made. The patient was immediately taken to the operating room for decompression surgery. Emergency compartment fasciotomy was performed. After fasciotomy, necrotomy was performed. Furthermore, brachiocephalic AV fistula was ligated. Postoperative evaluation obtained good radial and ulnar artery. Six months after the surgery, the wound was fully healed and no sign of neuromuscular or vascular deficit. Conclusion: Compartment syndrome is a possible complication after AV fistula formation that can have disastrous consequences. However, it can be effectively treated if detected and treated early. Prognosis of compartment syndrome after fasciotomy depends on how quickly the condition is diagnosed and treated.

Acute Compartment Syndrome in Pediatric Patients on Extracorporeal Membrane Oxygenation Support.

When acute compartment syndrome (ACS) occurs in pediatric patients requiring venoarterial extracorporeal membrane oxygen (VA ECMO) support, there is little data to guide surgeons on appropriate management. The purpose of this study is to characterize the presentation, diagnosis, timeline, and outcomes of patients who developed this complication. This is a single-center retrospective case series of children below 19 years old on VA ECMO support who subsequently developed extremity ACS between January 2016 and December 2022. Outcomes included fasciotomy findings, amputation, mortality, and documented function at the last follow-up. Of 343 patients on VA ECMO support, 18 (5.2%) were diagnosed with ACS a median 29 hours after starting ECMO. Initial cannulation sites included 8 femoral, 6 neck, and 4 central. Femoral artery cannulation was associated with an increased risk of ACS [odds ratio=6.0 (CI: 2.2 to 15), P <0.0001]. In the hospital, the mortality rate was 56% (10/18). Fourteen (78%) patients received fasciotomies a median of 1.2 hours after ACS diagnosis. Only 4 (29%) patients had all healthy muscles at initial fasciotomy, while 9 (64%) had poor muscular findings in at least 1 compartment. Patients with worse findings at fasciotomy had a significantly longer duration between ischemia onset and ACS diagnosis. Patients required a median of 1.5 additional procedures after fasciotomy, and only 1 (7%) developed a surgical site infection. Of the 7 surviving fasciotomy patients, 2 required amputations, 3 developed an equinus contracture, 1 developed foot drop, and 3 had no ACS-related deficits. Four patients did not receive fasciotomies: 3 were deemed too ill and later died, and 1 was diagnosed too late to benefit. The only surviving nonfasciotomy patient required bilateral amputations. Pediatric ECMO-associated ACS is not exclusive to patients with femoral artery cannulation. The majority of fasciotomy patients were diagnosed with ACS after muscle necrosis had already started. We were unable to definitively conclude whether fasciotomies provide better outcomes. There is a need for increased awareness and earlier recognition of this rare yet potentially devastating complication. Level IV-retrospective case series.

Axillary Plexus Block for Anesthesia Management in Patients with Acute Compartment Syndrome after Primary Percutaneous Coronary Intervention (PCI) Transradial Approach: A Case Report

Background: Acute compartment syndrome is a rare complication of the percutaneous Coronary Intervention (PCI) transradial approach but it is very hand-threatening. Treatment for acute compartment syndrome is emergent fasciotomy of the affected compartments to reduce intracompartmental pressure. Axillary plexus block is an excellent choice of anesthesia technique for elbow, forearm, and hand surgery.&#x0D; Case presentation: An 80-year-old, 60 kg, 168 cm man was consulted to our department with a painful swelling on his right upper arm and hand that began three hours after a primary PCI procedure. Previously, the patient had a history of hypertension and diabetes mellitus. The supporting examination results were notable for anemia (Hemoglobin 7,5 g/dL), thrombocytopenia (78 x103/uL), elevated hemostasis function (International Normalized Ratio 1.43), and high blood sugar (360 mg/dL) from echocardiography results anteroseptal and lateral hypokinetic. Before we did block, the patient was given ketamine 10 mcg IV and fentanyl 25 mcg IV for sedation. Axillary plexus block, as a type of regional anesthesia under ultrasound guidance, is a reliable substitute for general anesthesia in high-risk patients, and we do it with a dose of 20 ml of solution (50 mg (10 ml) isobaric bupivacaine 0.5% + 200 mg lidocaine 2% diluted with 20 ml normal saline). During the surgery, the patient was hemodynamically stable. After the operation, the patient was readmitted to the intensive cardiac care unit (ICCU).&#x0D; Conclusion: Axillary plexus block can be an alternative to general anesthesia in patients who will undergo fasciotomy surgery after percutaneous coronary intervention transradial approach with stable hemodynamics during surgery and well-controlled pain after the surgery.

Clinical and radiological risk factors associated with the occurrence of acute compartment syndrome in tibial fractures: a systematic review of the literature.

Acute compartment syndrome (ACS) is an orthopedic emergency that may lead to devastating sequelae. Diagnosis may be difficult. The aim of this systematic review is to identify clinical and radiological risk factors for ACS occurrence in tibial fractures. PubMed® database was searched in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines. Additional articles were found by a manual research of selected references and authors' known articles. The identification process individualized 2758 via database and 30 via other methods. After screening and eligibility assessment, 29 articles were included. Age, gender, occupation, comorbidities, medications, habits, polytrauma, multiple injuries, mechanism, sports, site, open vs closed, contiguous lesion, classification, and pattern were found to be related to ACS occurrence. Younger age and male gender are strong independent risk factors in tibial plateau and shaft fractures. High-energy fractures, polytrauma, more proximal fractures and fractures with contiguous skeletal lesions are aggravating risk factors; higher AO/OTA and Schatzker classification types, increased displacement of the tibia relative to the femur, and increased tibial joint surface width are associated risk factors in tibial plateau fractures; higher AO Foundation/Orthopaedic Trauma Association classification types and subgroups and more proximal fractures within the diaphysis are associated risk factors in tibial shaft fracture. Open fractures do not prevent ACS occurrence. Increased fracture length is the only factor suggesting a higher risk of ACS in tibial pilon fractures. The presence of each independent predictor may have a cumulative effect increasing the risk of ACS occurrence.

Exogenous Peptide Injection Causing Medical Thigh Compartment Syndrome

BackgroundAcute compartment syndrome can be caused by any condition that increases the pressure of an intracompartmental muscular space, resulting in ischemia, which is a limb-threatening emergency. This case report is the first known documented example of an exogenously injected peptide causing compartment syndrome. The use of natural supplements and holistic therapies is on the rise, specifically, peptide injections. It is important to obtain the history of use and routes of administration of these substances. Case ReportWe present a case of a 43-year-old man who presented to the Emergency Department with worsening thigh pain. The patient had injected a “peptide cocktail” into his thigh 3 days prior. Physical examination revealed trace pitting edema of the left leg with moderate muscle spasm and tenderness of the medial aspect of the distal thigh with associated numbness along the medial aspect of the knee. Point-of-care ultrasound detected intramuscular edema and free fluid in the leg. He was found to have acute compartment syndrome of the thigh secondary to the peptide cocktail injection, causing a large hematoma posterior to the adductor magnus. The patient required fasciotomy and hematoma evacuation. He ultimately left against medical advice during his hospitalization. Why Should an Emergency Physician Be Aware of This?In an age when many patients look for supplements to aid with weight loss and muscle growth, it is essential to be aware of peptide injection therapies and the potential complication of compartment syndrome.

Olink proteomics analysis uncovers the landscape of inflammation-related proteins in patients with acute compartment syndrome.

Our primary purpose was to explore the landscape of inflammation-related proteins, and our second goal was to investigate these proteins as potential biomarkers of acute compartment syndrome (ACS), which is a serious complication of tibial fractures. We collected sera from 15 healthy subjects (control group, CG) and 30 patients with tibial fractures on admission day, comprising 15 patients with ACS (ACS group, AG) and 15 patients without ACS (fracture group, FG). Ten samples in each group were analyzed by the inflammation panel of Olink Proteomics Analysis, and all samples were verified by an ELISA. Receiver-operating characteristic (ROC) curve analysis was performed to identify the diagnostic ability and cutoff values of potential biomarkers. Our findings showed that the levels of IL6, CSF-1, and HGF in the FG were significantly higher than those in the CG. Similar results were found between the AG and CG, and their cutoff values for predicting ACS compared with the CG were 9.225 pg/ml, 81.04 pg/ml, and 0.3301 ng/ml, respectively. Furthermore, their combination had the highest diagnostic accuracy. Notably, compared with FG, we only found a higher expression of CCL23 in the AG. Additionally, we identified 35.75 pg/ml as the cutoff value of CCL23 for predicting ACS in patients with tibial fractures. We identified CCL23 as a potential biomarker of ACS in comparison with tibial fracture patients and the significance of the combined diagnosis of IL6, CSF-1, and HGF for predicting ACS compared with healthy individuals. Furthermore, we also found their cutoff values, providing clinicians with a new method for rapidly diagnosing ACS. However, we need larger samples to verify our results.

PROGRESSIVE MUSCLE HYPOXIA RESEARCH: COULD PHARMACOLOGICAL AGENTS BE USED TO LIMIT REPERFUSION INJURY AT THE TIME OF FASCIOTOMY TO TREAT ACUTE COMPARTMENT SYNDROME?

AbstractBackgroundProgressive muscle ischaemia results in reduced aerobic respiration and increased anaerobic respiration, as cells attempt to survive in a hypoxic environment. Acute compartment syndrome (ACS) is a progressive form of muscle ischaemia that is a surgical emergency resulting in the production of Lactic acid by cells through anaerobic respiration. Our previous research has shown that it is possible to measure H+ ions concentration (pH) as a measure of progressive muscle ischaemia (in vivo) and hypoxia (in vitro). Our aim was to correlate intramuscular pH readings and cell viability techniques with the intramuscular concentration of key metabolic biomarkers [adenosine triphosphate (ATP), Phosphocreatine (PCr), lactate and pyruvate], to assess overall cell health in a hypoxic tissue model.MethodsNine euthanised Wistar rats were used in a non-circulatory model. A pH catheter was used to measure real-time pH levels from one of the exposed gluteus medius muscles, while muscle biopsies were taken from the contralateral gluteus medius at the start of the experiment and subsequently at every 0.1 of a pH unit decline. The metabolic biomarkers were extracted from the snap frozen muscle biopsies and analyzed with standard fluorimetric method. Another set of biopsies were stained with Hoechst 33342, Ethidium homodimer-1 and Calcein am and imaged with a Zeiss LSM880 confocal microscope.ResultsOur study shows that the direct pH electrode readings decrease with time and took an average of 69 minutes to drop to a pH of 6.0. The concentrations of ATP, pyruvate and PCr declined over time, and the concentration of lactate increased over time. At pH 6.0, both ATP and PCr concentrations had decreased by 20% and pyruvate has decreased by 50%, whereas lactate had increased 6-fold. The majority of cells were still viable at a pH of 6.0, suggesting that skeletal muscle cells are remarkably robust to hypoxic insult, although this was a hypoxic model where reperfusion was not possible.ConclusionsOur research suggests that histologically, skeletal muscle cells are remarkably robust to hypoxic insult despite the reduction in the total adenine nucleotide pool, but this may not reflect the full extent of cell injury and quite possibly irreversible injury. The timely restoration of blood flow in theory should halt the hypoxic insult, but late reperfusion results in cellular dysfunction and cell death due to localised free radical formation. Further research investigating the effects of reperfusion in vivo are warranted, as this may identify an optimal time for using pharmacological agents to limit reperfusion injury, around the time of fasciotomy to treat acute compartment syndrome.Declaration of Interest(b) declare that there is no conflict of interest that could be perceived as prejudicing the impartiality of the research reported:I declare that there is no conflict of interest that could be perceived as prejudicing the impartiality of the research project.

Surgical Fasciotomies for Pediatric Acute Compartment Syndrome, and Overview

Introduction: The goal of treatment is firstly to save the patient's life and secondly to save the damaged climb. Fasciectomy is the only accepted treatment for compartment syndrome and should be performed promptly after the diagnosis is made. The results after fasciectomy are best when there is no delay in treatment. Method: Clinically determined according to the "5 P's" and measured Intracompartmental Pressure (ICP) with P ≥ 30 mmHg. Perform traditional Fasciotomies surgery on all patients. Results: There were four patients; Mean age: 54 months ± 31.749; Girl: 03; Boy: 01; Fall from hight: 2; Sport trauma: 01; Pedestrian in a car accident: 01; Mean - Intracompartmental Pressure (ICP): 53.75 mmHg.The most common mechanisms of injury are pedestrians struck by motor vehicles, falls, sports, and vehicle occupants in motor vehicle crashes. Forearm fractures are the most common cause in the upper extremity, and fractures of the tibia and/or fibula are most common in the lower extremity. Conclusions: Fractures significantly increase the risk of developing compartment syndrome in both forearm and leg fractures. The patients were transferred directly from the emergency room to the operating room, suggesting that the remaining developed compartment syndrome after admission or late diagnosis.

Tibial Plateau Fractures Complicated by Compartment Syndrome are Associated with a Three Times Higher Cost of Care.

To determine the impact of acute compartment syndrome (ACS) and identify cost-drivers of 1-year total treatment costs for operative tibial plateau fractures. Retrospective review. Level 1 Trauma Center. 337 patients with tibial plateau fractures, 24 of which were complicated by ACS. The primary outcome was total treatment cost over the first year for operatively treated tibial plateau fractures. The secondary objective was to use regression analysis to identify significant cost drivers. The diagnosis of ACS was associated with 2.85 times higher in total treatment cost (p < 0.001). Acute compartment syndrome demonstrated increased total treatment cost when controlling for polytrauma (p < 0.001) and post-operative infection (p < 0.001). Regression analysis identified 5 variables significantly associated with total cost of care: Body Mass Index, Injury Severity Score, ACS, Staged External Fixation, and Locking Fixation (p < 0.001; R2 = 0.57). The diagnosis of ACS had the largest impact on total cost with a 3.5x greater impact on cost compared to the next highest variable, staged external-fixation. Tibial plateau fractures complicated by ACS are associated with 2.85 times higher treatment costs over a 1-year period. There were 5 significant variables identified by regression analysis with ACS having the highest impact on total treatment. Together, these 5 factors account for 57% of treatment cost variability.

Postfasciotomy Classification System for Acute Compartment Syndrome of the Leg.

Acute compartment syndrome (ACS) is a true emergency. Even with urgent fasciotomy, there is often muscle damage and need for further surgery. Although ACS is not uncommon, no validated classification system exists to aid in efficient and clear communication. The aim of this study was to establish and validate a classification system for the consequences of ACS treated with fasciotomy. Using a modified Delphi method, an international panel of ACS experts was assembled to establish a grading scheme for the disease and then validate the classification system. The goal was to articulate discrete grades of ACS related to fasciotomy findings and associated costs. A pilot analysis was used to determine questions that were clear to the respondents. Discussion of this analysis resulted in another round of cases used for 24 other raters. The 24 individuals implemented the classification system 2 separate times to compare outcomes for 32 clinical cases. The accuracy and reproducibility of the classification system were subsequently calculated based on the providers' responses. The Fleiss Kappa of all raters was at 0.711, showing a strong agreement between the 24 raters. Secondary validation was performed for paired 276 raters and correlation was tested using the Kendall coefficient. The median correlation coefficient was 0.855. All 276 pairs had statistically significant correlation. Correlation coefficient between the first and second rating sessions was strong with the median pair scoring at 0.867. All surgeons had statistically significant internal consistency. This new ACS classification system may be applied to better understand the impact of ACS on patient outcomes and economic costs for leg ACS.

Acute compartment syndrome of the lower limbs: Fasciotomy or dermofasciotomy? A cadaver study of compartment pressures

BackgroundAcute compartment syndrome (ACS) of the lower limbs is a function-threatening event usually managed by extended dermofasciotomy. Closure of the skin may be delayed, creating a risk of complications when there is an underlying fracture. Early treatment at the pre-ACS stage might allow isolated fasciotomy with no skin incision. The primary objective of this study was to compare intracompartmental pressure (ICP) changes after fasciotomy and after dermofasciotomy. The secondary objectives were to evaluate potential associations linking the starting ICP to achievement of an ICP below the physiological cut-off of 10mm Hg and to determine whether the ICP changes after fasciotomy and dermofasciotomy varied across muscle compartments. HypothesisFasciotomy with no skin incision may not provide a sufficient ICP decrease, depending on the initial ICP value. Material and methodsA previously validated model of cadaver ACS of the lower limbs was used. Saline was injected gradually to raise the ICP to>15mmHg (ICP15), >30mmHg (ICP30), and >50mmHg (ICP50). We studied 70 leg compartments (anterior, lateral, and superficial posterior) in 13 cadavers (mean age, 89.1±4.6years). ICP was monitored continuously. Percutaneous, minimally invasive fasciotomy consisting in one to three 1-cm incisions was performed in each compartment. ICP was measured before and after fasciotomy then after subsequent skin incision. The objective was to decrease the ICP below 10mmHg after fasciotomy or dermofasciotomy. ResultsOverall, mean ICP was 37.8±19.1mmHg after the injection of 184.0±133.01mL of saline. In the ICP15 group, the mean ICP of 16.1mmHg fell to 1.4mmHg after fasciotomy (ΔF=14.7) and 0.3mmHg after dermofasciotomy (ΔDF=1.1). Corresponding values in the ICP30 group were 33.9mmHg, 4.7mmHg (ΔF=29.2), and 1.2mmHg (ΔDF=3.5); and in the ICP50 group, 63.7mmHg, 17.0mmHg (ΔF=46.7), and 1.2mmHg (ΔDF=15.8). Thus, in the group with initial pressures >50mmHg, the ICP decrease was greater after both procedures, but fasciotomy alone nonetheless failed to achieve physiological values (<10mmHg). The pressure changes were not significantly associated with the compartment involved (anterior, lateral, or superficial posterior) (p<0.05). ConclusionUnder the conditions of this study, higher baseline ICPs were associated with larger ICP drops after fasciotomy and dermofasciotomy. Nevertheless, when the baseline ICP exceeded 50mmHg, fasciotomy alone failed to decrease the ICP below 10mmHg. Adding a skin incision achieved this goal. Level of evidenceIV, experimental study.

Electrical impedance myography for the early detection of muscle ischemia secondary to compartment syndrome: a study in a rat model

Acute Compartment Syndrome (ACS) is one of the most devastating orthopedic conditions, affecting any of the body’s many compartments, which, if sufficiently severe, may result in disability and amputation. Currently, intra-compartmental pressure measurements serve as the gold standard for diagnosing ACS. Diagnosing limbs at risk for ACS before irreversible damage to muscle and nerve is critical. Standard approaches for diagnosing impending compartment syndrome include clinical evaluation of the limb, such as assessment for “tightness” of the overlying skin, reduced pulses distally, and degree of pain, none of which are specific or sensitive. We have proposed a novel method to detect ACS via electrical impedance myography (EIM), where a weak, high-frequency alternating current is passed between one pair of electrodes through a region of tissue, and the resulting surface voltages are measured via a second pair. We evaluated the ability of EIM to detect early muscle ischemia in an established murine model of compression-induced muscle injury, where we collected resistance, reactance, and their dimensionless product, defined as Relative Injury Index (RII) during the study. Our model generated reproducible hypoxia, confirmed by Hypoxyprobe™ staining of endothelial regions within the muscle. Under conditions of ischemia, we demonstrated a reproducible, stable, and significant escalation in resistance, reactance, and RII values, compared to uninjured control limbs. These data make a reasonable argument for additional investigations into using EIM for the early recognition of muscle hypoperfusion and ischemia. However, these findings must be considered preliminary steps, requiring further pre-clinical and clinical validation.

Risk Factors for Surgical Site Infections Following Fasciotomy in Patients With Acute Compartment Syndrome: A Study on the February 2023 Kahramanmaraş Earthquake.

Surgical site infections (SSIs) developing after fasciotomy are difficult to treat, costly, and an important source of mortality and morbidity. This study aimed to determine the risk factors affecting the development of SSI in patients who underwent fasciotomy with the diagnosis of acute compartment syndrome (ACS) within 72 hours after two consecutive earthquakes of 7.7 and 7.6 magnitude that occurred in Kahramanmaraş on February 6, 2023. A total of 116 patients were retrospectively analyzed. Patients were divided into two groups: those who developed SSI and those who did not. In this study, variables such as basic demographic characteristics, time of fasciotomy, center performing fasciotomy, type of wound closure, affected extremity, concomitant renal failure, hyperbaric oxygen (HBO) therapy, blood creatine kinase (CK) level were examined. Of 116 patients, 58 (50%) had SSI. It was statistically observed that patients who underwent treatment with vacuum-assisted closure (VAC), those who underwent primary closure with the shoelace method, those who went into renal failure, and those whose fasciotomy was performed in an earthquake zone had a higher incidence of SSI (p<0.001). Blood CK level above 17.839 seemed to be a risk factor according to receiver operating characteristic (ROC) analysis (P<0.01). Age (p=0.193), gender (p=0.125), fasciotomy time (p=0.843), lower extremity (p=0.234), upper extremity (p=0.806), and HBO treatment (p=0.56) were not associated with SSI. Infection was found to be a significant risk factor for amputation (p<0.001). The use of VAC as a wound closure technique for SSI after fasciotomy in patients who developed ACSdue to the earthquake, the presence of renal failure in the patients, and performing fasciotomy in the earthquake zone were independent risk factors. A blood CK level above 17.839 was also determined as a risk factor, but the confidence interval was found to be low.

Compartments of the crural fascia: clinically relevant ultrasound, anatomical and histological findings

PurposeCompartment syndrome is a surgical emergency that can occur in any part of the body and can cause cell necrosis when maintained over time. The resulting defects can affect the nerves, muscle cells, bone tissue, and other connective tissues inside the compartment, and fasciotomy has to be performed. The anatomical and histological characteristics of the leg make acute, chronic, and exertional compartment syndrome more likely in this limb. For these reasons, knowledge of the ultrasound, anatomical, and histological features of the crural fascia can help in the treatment of leg compartment syndrome.MethodsTwenty-one cryopreserved lower limbs from adult cadavers and from one 29-week-old fetus were obtained from the dissection room. They were examined by ultrasound and a subsequent anatomical dissection and microscopy to study the crural fascia and its relationship with the different muscles. Anthropometric measurements were taken of the distances from the head of the fibula and lateral malleolus to the origin of the tibialis anterior muscle in the crural fascia, the exit of the superficial fibular nerve, and the fascia covering the deep posterior muscles of the leg.ResultsThe crural fascia has very important clinical relationships, which can be identified by ultrasound, as the origin of the tibialis anterior muscle at 16.25 cm from the head of the fibula and the exit of the superficial fibular nerve that crosses this fascia at 21.25 cm from the head of the fibula. Furthermore, the presence of a septum that fixes the deep posterior muscles of the leg and the vessels and nerve can be seen by ultrasound and can explain the possible development of a posterior compartmental syndrome of the leg. Awareness of these features will help to keep these structures safe during the surgical treatment of compartment syndrome.ConclusionThe ultrasound study allows identification of anatomical structures in the leg and, thus, avoids damage to them during surgery for compartmental syndromes.

Single-Incision Fasciotomy Decreases Infection Risk Compared with Dual-Incision Fasciotomy in Treatment of Tibial Plateau Fractures With Acute Compartment Syndrome.

Comparison of surgical site infection (SSI) rates in tibial plateau fractures with acute compartment syndrome treated with single-incision (SI) versus dual-incision (DI) fasciotomies. Retrospective cohort study. Two, Level-1, academic, trauma centers. Between January 2001 and December 2021, one-hundred ninety patients with a diagnosis of tibial plateau fracture and acute compartment syndrome met inclusion criteria (SI: n = 127, DI: n = 63) with a minimum of 3-month follow-up after definitive fixation. Emergent 4-compartment fasciotomy, using either SI or DI technique, and eventual plate and screw fixation of the tibial plateau. The primary outcome was SSI requiring surgical debridement. Secondary outcomes included nonunion, days to closure, method of skin closure, and time to SSI. Both groups were similar in demographic variables and fracture characteristics (all P > 0.05). The overall infection rate was 25.8% (49 of 190), but the SI fasciotomy patients had significantly fewer SSIs compared with the DI fasciotomy patients [SI 18.1% vs. DI 41.3%; P < 0.001; OR 2.28, (confidence interval, 1.42-3.66)]. Patients with a dual (medial and lateral) surgical approach and DI fasciotomies developed an SSI in 60% (15 of 25) of cases compared with 21.3% (13 of 61) of cases in the SI group ( P < 0.001). The nonunion rate was similar between the 2 groups (SI 8.3% vs. DI 10.3%; P = 0.78). The SI fasciotomy group required fewer debridement's ( P = 0.04) until closure, but there was no difference in days until closure (SI 5.5 vs. DI 6.6; P = 0.09). There were zero cases of incomplete compartment release requiring return to the operating room. Patients with DI fasciotomies were more than twice as likely to develop an SSI compared with SI patients despite similar fracture and demographic characteristics between the groups. Orthopaedic surgeons should consider prioritizing SI fasciotomies in this setting. Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Prehospital management of earthquake crush injuries: A collective review.

Earthquakes are natural disasters which can destroy the rural and urban infrastructure causing a high toll of injuries and death without advanced notice. We aim to review the prehospital medical management of earthquake crush injuries in the field. PubMed was searched using general terms including rhabdomyolysis, crush injury, and earthquake in English language without time restriction. Selected articles were critically evaluated by three experts in disaster medicine, emergency medicine, and critical care. The medical response to earthquakes includes: (1) search and rescue; (2) triage and initial stabilization; (3) definitive care; and (4) evacuation. Long-term, continuous pressure on muscles causes crush injury. Ischemia-reperfusion injury following the relieving of muscle compression may cause metabolic changes and rhabdomyolysis depending on the time of extrication. Sodium and water enter the cell causing cell swelling and hypovolemia, while potassium and myoglobin are released into the circulation. This may cause sudden cardiac arrest, acute extremity compartment syndrome, and acute kidney injury. Recognizing these conditions and treating them timely and properly in the field will save many patients. Majority of emergency physicians who have worked in the field of the recent Kahramanmaraş 2023, Turkey, earthquakes, have acknowledged their lack of knowledge and experience in managing earthquake crush injuries. We hope that this collective review will cover the essential knowledge needed for properly managing seriously crushed injured patients in the earthquake field.

Forearm Compartment Syndrome due to Transradial PCI in STEMI: Case Series of What Can Go Wrong and Lesson Learned

The trans-radial approach (TRA) is shown to be superior in reducing bleeding complications and associated with lower mortality with a similar procedural success rate in ST-Elevated Myocardial Infarction (STEMI) patients compared to the trans-femoral approach. Nevertheless, complications such as forearm hematoma and, in rare cases, acute compartment syndrome (ACS) may develop, thus requiring a prompt surgical procedure. Here, we present two successful emergency fasciotomy cases as ACS treatment following primary percutaneous coronary intervention after STEMI. Both patients show normal neurological and muscular function and normal artery flow on both hands afterward.

Analysis of acute extremity compartment syndrome using a genealogic population database.

Acute extremity compartment syndrome ("CS") is an under-researched, highly morbid condition affecting trauma populations. The purpose of this study was to analyze incidence rates and risk factors for extremity compartment syndrome using a high-quality population database. Additionally, we evaluated heritable risk for CS using available genealogic data. We hypothesized that diagnosis of extremity compartment syndrome would demonstrate heritability. Adult patients with fractures of the tibia, femur, and upper extremity were retrospectively identified by ICD-9, ICD-10, and CPT codes from 1996 to 2020 in a statewide hospital database. Exposed and unexposed cohorts were created based on a diagnosis of CS. Available demographic data were analyzed to determine risk factors for compartment syndrome using logistic regression. Mortality risk at the final follow-up was evaluated using Cox proportional hazard modeling. Patients with a diagnosis of CS were matched with those without a diagnosis for heritability analysis. Of 158,624 fractures, 931 patients were diagnosed with CS. Incidence of CS was 0.59% (tibia 0.83%, femur 0.31%, upper extremity 0.27%). Male sex (78.1% vs. 46.4%; p < 0.001; RR = 3.24), younger age at fracture (38.8 vs. 48.0years; p < 0.001; RR = 0.74), Medicaid enrollment (13.2% vs. 9.3%; p < 0.001; RR = 1.58), and smoking (41.1% vs. 31.1%; p < 0.001; RR 1.67) were significant risk factors for CS. CS was associated with mortality (RR 1.61, p < 0.001) at mean follow-up 8.9years in the CS cohort. No significant heritable risk was found for diagnosis of CS. Without isolating high-risk fractures, rates of CS are lower than previously reported in the literature. Male sex, younger age, smoking, and Medicaid enrollment were independent risk factors for CS. CS increased mortality risk at long-term follow-up. No heritable risk was found for CS. III.

Mini approaches fasciotomy combined with vacuum sealing drainage for acute compartment syndrome caused by fractures in children.

Acute compartment syndrome (ACS) is an urgent, critical condition that requires immediate fasciotomy once diagnosed. Traditionally, fasciotomy of the forearms and lower leg involves one or two long approaches. Our previous study demonstrated that mini approaches fasciotomy was an effective method to treat ACS. This study is aimed at further evaluating the limb functions and complications of mini approaches combined with vacuum sealing drainage (VSD) for treating ACS caused by fractures in the forearms and lower legs. This was a retrospective cross-sectional study, and after applying the inclusion and exclusion criteria, we reviewed 126 children who underwent mini treatment approaches for ACS from Jan 2008 to Jan 2022. The selected patients were divided into two groups: group A (ACS group; 58 patients aged 7.77±3.45 years) and group B (ACS combined with VSD; 68 patients aged 7.17±3.55 years). Patients' clinical data were collected. The patients were followed up, and muscle function in the forearms and lower legs was evaluated. The overall incidence of lower legs and forearmsACS was 126/29642 (0.425%). The most common mechanisms of injury were fractures of the forearm (39/74, 52.7%), supracondylar humerus (31/74 41.9%), and elbow (4/74, 5.4%), while those for the lower legs were fractures of the proximal tibia (19/52, 36.5%), midshaft of tibia (25/52, 48.1%), and distal tibia (7/52, 13.5%). According to Flynn's assessment, no significant difference was observed between the two groups (p=0.151). However, the two groups showed significant differences in the hospitalization time (p=0.002) and incision infection rate (0.043). Mini approaches fasciotomy combined with VSD is an effective and safe method to treat ACS of the forearms and lower legs caused by fractures in children. This method involves a single-stage surgery and is associated with shorter hospitalization time and incision infection.
