Acute compartment syndrome (ACS) is a severe orthopedic issue that, if left untreated, can result in lasting nerve and muscle damage or even necessitate amputation. The association between admission laboratory blood test indicators and the occurrence of ACS in patients with tibial diaphysis fractures is currently a subject of debate. The objective of this research was to identify the contributing factors for ACS in individuals suffering from tibial diaphysis fractures. In this retrospective study, we collected data on a total of 705 individuals from our hospital, comprising 86 ACS patients and 619 non-ACS patients with tibial diaphysis fractures. These participants were categorized into two distinct groups: the ACS group and the non-ACS group. Despite the inherent limitations associated with retrospective analyses, such as potential biases in data collection and interpretation, we conducted a comprehensive analysis of demographics, comorbidities, and admission lab results. Our analytical approach included univariate analysis, logistic regression, and receiver operating characteristic (ROC) curve analysis techniques, aiming to mitigate these limitations and provide robust findings. The statistical analysis revealed several predictors of ACS, including gender (p = 0.011, OR = 3.200), crush injuries (p = 0.004, OR = 4.622), lactic dehydrogenase (LDH) levels (p < 0.001, OR = 1.003), and white blood cell (WBC) count (p < 0.001, OR = 1.246). Interestingly, the study also found that certain factors, such as falls on the same level (p = 0.007, OR = 0.334) and cholinesterase (CHE) levels (p < 0.001, OR = 0.721), seem to provide a degree of protection against ACS. In order to better predict ACS, the ROC curve analysis was employed, which determined threshold values for LDH and WBC. The established cut-off points were set at 266.26 U/L for LDH and 11.7 × 10 9 cells per liter for WBC, respectively. Our research has successfully pinpointed gender, crush injuries, LDH levels, and white blood cell (WBC) count as crucial risk factors for the development of ACS in patients experiencing tibial diaphysis fractures. Furthermore, by establishing the cut-off values for LDH and WBC, we have facilitated a more personalized assessment of ACS risk, enabling clinical doctors to implement targeted early interventions and optimize patient outcomes., (© 2024.

Purpose: The predictors of muscle necrosis after acute compartment syndrome (ACS) remain debated. This study aimed to investigate the predictors for muscle necrosis in ACS patients., Methods: We collected data on ACS patients following fractures from January 2010 to November 2022. Patients were divided into the muscle necrosis group (MG) and the non-muscle necrosis group (NG). The demographics, comorbidities, and admission laboratory indicators were computed by univariate analysis, logistic regression analysis, and receiver-operating characteristic (ROC) curve analysis., Results: In our study, the rate of MN was 37.6% (83 of 221). Univariate analysis showed that numerous factors were associated with muscle necrosis following ACS. Logistic regression analysis indicated that crush injury (p = 0.007), neutrophil (NEU, p = 0.001), creatine kinase myocardial band (CKMB, p = 0.047), and prothrombin time (PT, p = 0.031) were risk factors. Additionally, ROC curve analysis identified 11.415 10 9 /L, 116.825 U/L, and 12.51 s as the cut-off values for NEU, CKMB, and PT to predict muscle necrosis, respectively. Furthermore, the combination of NEU, CKMB, and PT had the highest diagnostic accuracy., Conclusions: Our findings showed that crush injury and the level of NEU, CKMB, and PT were risk factors for muscle necrosis after ACS. Additionally, we also identified the cut-off values of NEU, CKMB, and PT and found the combination of crush injury, PT, and NEU with the highest diagnostic accuracy, helping us individualize the assessment risk of muscle necrosis to manage early targeted interventions., (© 2023.

Background: Compartment syndrome is a rare but serious entity with various causes. Timely diagnosis and treatment are essential., Case Description: We present a case of a 14-year-old boy with a crush injury of the forearm including a fracture of the radius and ulna. In addition, a traction injury of the brachial plexus was present. Despite the absence of pain, a fasciotomy was performed because of excessive swelling of the forearm with obvious bulging of the muscles intra-operatively., Conclusion: Compartment syndrome can develop at several places in the body, including the forearm. Disproportional pain is the most relevant symptom which can however be absent due to concurrent neurological injury. Surgical exploration is always warranted in case of a clinical suspicion of compartment syndrome to prevent severe complications.

Rationale: Acute compartment syndrome (ACS) is a feared complication following traumatic injuries. We describe the occurrence of silent ACS of the hand in a 2-year old patient with atypical symptoms., Patient Concerns: Our patient experienced massive swelling but minimal pain of the hand after a heavy bistro table with a stone tabletop had fallen on the right hand., Diagnosis: After monitoring the development of ACS for 1 night, we noted increased firmness of the swelling and impaired perfusion of the skin covering the palm and dorsum of the hand. Notably, the patient held the hand in an intrinsic minus position but did not complain of pain after administration of only a single (weight-matched) dose of ibuprofen. Our suspicion of ACS was confirmed intraoperatively because of the elevated intramuscular pressure (up to 60 mm Hg) in several hand compartments., Interventions: We performed surgical fasciotomy of all hand compartments, followed by temporary coverage of the wounds with Epigard synthetic skin substitute. The wounds were closed stepwise after 2 and 7 days, and occupational therapy was initiated after 3 weeks., Outcomes: At the 1-year follow-up, we noted unrestricted wrist and finger functions of the patient. The parents reported that there was no difference in the use of the 2 hands during daily activities., Lessons: The possible development of ACS should be borne in mind even in the absence of marked pain. Although the 3 A's (i.e., anxiety, agitation, and increased analgesic requirements) in the diagnosis of ACS in children are well established, some patients may experience only minimal pain. This challenges the correct and timely diagnosis of ACS in children, particularly if they are very young.

Acute compartment syndrome is a critical condition, most commonly arising as the result of high-energy trauma, fracture, and crush injury. Early diagnosis and treatment are imperative to avoid permanent functional damage to the affected extremity. Although isolated pedal compartment syndrome is well studied in adults, in the pediatric population, it has been seldom reported. Pediatric patients pose a unique challenge when diagnosing compartment syndrome. Their inability to appropriately verbalize symptoms and participate in physical examinations often causes a delay in diagnosis. We present the case of a 5-year-old female who developed compartment syndrome of her left foot 26 hours after sustaining an isolated crush injury to the distal forefoot. Her treatment included emergent fasciotomy in combination with 20 hyperbaric oxygen therapy treatments. The progression of her acute digital ischemia was monitored by using serial fluorescence microangiography studies performed at 17 hours, 7 days, and 3 weeks postinjury. Throughout these serial studies, improvement in hypofluorescence was noted involving the dorsolateral midfoot, as well as digits 3, 4, and 5, which correlated with physical examination. The patient went on to uneventfully autoamputate the distal aspects of digits 4 and 5 within 4 months of injury. At the 12-month follow-up visit, she denied any pain, sensory deficits, or functional disability and had returned to all preinjury activities. Our case study demonstrates the use of serial microangiography to monitor progression of acute ischemia associated with acute pediatric compartment syndrome and discusses prognostic capabilities., (Copyright © 2019 the American College of Foot and Ankle Surgeons.

Successful vitamin K antagonist (eg, warfarin) reversal with 4-factor prothrombin complex concentrate (4F-PCC) without vitamin K (phytonadione) for emergent surgery in a patient at moderate-to-high risk for thromboembolism is reported. This approach may decrease the risk for development of thrombus, as it limits the amount of time the patient's anticoagulation is subtherapeutic. It also may increase the risk of bleeding, so patient selection is essential if this strategy is employed. Caution must be exercised to complete the procedure or surgery in the window of peak 4F-PCC effect (∼1-6 hours postinfusion)., Competing Interests: Conflicts of Interest: None declared., (2016 BMJ Publishing Group Ltd.)
