Extracorporeal Membrane Oxygenation-Associated Compartment Syndrome: Review of a National Database.

INTRODUCTION: Extracorporeal membrane oxygenation (ECMO)-associated compartment syndrome (CS) is a rare complication seen in critically ill patients. The epidemiology and management of ECMO-associated CS in the upper extremity (UE) and lower extremity (LE) are poorly defined in the literature. We sought to determine the epidemiology and characterize treatment and outcomes of UE-CS compared to LE-CS in the setting of ECMO therapy. METHODS: Adult patients undergoing ECMO therapy were identified in the Nationwide Readmission Database (2015-2019) and followed up for 6 months. Patients were stratified based on UE-CS versus LE-CS. Primary outcomes were fasciotomy and amputation. All-cause mortality and length of stay were also collected. Risk-adjusted modeling was performed to determine patient- and hospital-level factors associated with differences in the management UE-CS versus LE-CS while controlling for confounders. RESULTS: A total of 24,047 cases of ECMO during hospitalization were identified of which 598 were complicated by CS. Of this population, 507 cases were in the LE (84.8%), while 91 (15.5%) were in the UE. After multivariate analysis, UE-CS patients were less likely to undergo fasciotomy (50.5 vs. 70.9; P = 0.013) and were less likely to undergo amputation of the extremity (3.3 vs. 23.7; P = 0.001) although there was no difference in mortality (58.4 vs. 65.4; P = 0.330). CONCLUSIONS: ECMO patients with CS experience high mortality and morbidity. UE-CS has lower rates of fasciotomy and amputations, compared to LE-CS, with similar mortality. Further studies are needed to elucidate the reasons for these differences.

Sex differences in outcomes after revascularization for acute lower limb ischemia: Propensity score adjusted analysis.

BACKGROUND: Previous reports have suggested higher rates of mortality and amputation for female patients in acute lower limb ischemia (ALI). The aims of the present study were to investigate if there is a difference in mortality, amputation, and fasciotomy between the sexes. METHODS: A retrospective cohort study of consecutive patients undergoing index revascularization for ALI between 2001 and 2018 was conducted. A propensity score was created through a logistic regression with female/male sex as an outcome. Cox regression analyses for 90-day and 1-year mortality, combining major amputation/mortality, and logistic regression for major bleeding and fasciotomy, were performed. All analyses were performed with and without adjusting for propensity score. RESULTS: A total of 709 patients were included in the study of which 45.9% were women. Mean age was 72.1 years. Females were older and had higher rates of atrial fibrillation, embolic disease, and lower estimated glomerular filtration rate, while men more often had anemia and chronic peripheral arterial disease. Mortality at 1 year was 21.2% for women and 14.7% for men. The adjusted hazard ratio for 1-year mortality was 0.99 (95% CI 0.67-1.46). Fasciotomy was performed in 7.1% of female and 12.8% of male patients; the adjusted odds ratio was 0.52 (95% CI 0.29-0.91). CONCLUSION: Sex was not found to be an independent risk factor for mortality or combined major amputation/mortality after revascularization for acute lower limb ischemia, whereas women had lower odds of undergoing fasciotomy. Whether women are underdiagnosed or do not develop acute compartment syndrome in the lower leg as often as men should be evaluated prospectively.

Delayed onset of neonatal compartment syndrome associated with compound fetal presentation.

Neonatal compartment syndrome, although rare, has a classic presentation with sentinel skin findings and development of swelling, erythema, and tenderness of the affected extremity. Neonatal compartment syndrome requires prompt surgical intervention to preserve the affected limb and ensure its normal growth and development. Our patient was born at term via vaginal delivery complicated by a compound presentation involving the left upper extremity. No physical exam abnormalities were noted at birth, but she developed signs of neonatal compartment syndrome by 15 h of life. She was surgically treated at 22 h of life and recovered well. At one year of age, she has normal growth and function of the affected extremity. Our case adds to the growing literature associating neonatal compartment syndrome with a compound fetal presentation.

Female patients have greater improvement in pain symptoms and physical activity after fasciotomy for treatment of chronic exertional compartment syndrome of the lower leg.

PURPOSE: The purpose of this study was to identify sex differences in postoperative outcomes and return-to-sport rates after fasciotomy for treatment of chronic exertional compartment syndrome (CECS) of the lower leg. It was hypothesised that male CECS patients would have a higher rate of return to sport than female CECS patients. METHODS: A retrospective cohort study was conducted involving patients who underwent primary fasciotomy of one to four leg compartments for treatment of CECS at a single centre from 2010 to 2020. Each affected leg was treated as a separate subject. Postoperative outcomes included CECS pain frequency and severity, return to sport and Tegner activity level. Multivariable regression was used to determine if sex was an independent predictor of outcomes after adjusting for demographic and clinical covariates. p < 0.05 were considered significant. RESULTS: Eighty-one legs (44 M, 37 F) of 47 unique patients (34 of whom had bilateral symptoms) were included with a mean follow-up time of 51.5 ± 31.4 months. Male subjects were older (p < 0.001) and had higher body mass index (p < 0.001) compared to female subjects. Most subjects (84.0%) underwent two- or four-compartment fasciotomies. Female sex was found to be predictive of lower overall postoperative pain severity (p = 0.007), higher odds of return to sport (p = 0.04) and higher postoperative Tegner score (p = 0.005). However, female sex was not predictive of postoperative pain frequency, odds of reoperation or odds of return to sport to at least the presymptomatic level (all p < 0.05). CONCLUSION: Female sex is independently predictive of reduced overall pain severity, higher odds of return to sport and higher postoperative improvement in Tegner score following fasciotomy for treatment of lower-limb CECS. LEVEL OF EVIDENCE: III.

Evaluating the Need for Simultaneous Carpal Tunnel Release With Forearm Fasciotomy.

PURPOSE: The need to include simultaneous carpal tunnel release (sCTR) with forearm fasciotomy for acute compartment syndrome (ACS) or after vascular repair is unclear. We hypothesized that sCTR is more common when: 1) fasciotomies are performed by orthopedic or plastic surgeons, rather than general or vascular surgeons; 2) ACS occurred because of crush, blunt trauma, or fractures rather than vascular/reperfusion injuries; 3) elevated compartment pressures were documented. We also sought to determine the incidence of delayed CTR when not performed simultaneously. METHODS: Retrospective chart review identified patients who underwent forearm fasciotomy for ACS or vascular injury over a period of 10 years. Patient demographics, mechanism of ACS or indication for fasciotomy, surgeon subspecialty, compartment pressure measurements, inclusion of sCTR, complications, reoperations, and timing and method of definitive closure were analyzed. Logistic regression modeling was used to analyze predictors associated with delayed CTR. RESULTS: Fasciotomies were performed in 166 patients by orthopedic (63%), plastic (28%), and general/vascular (9%) surgeons. Orthopedic and plastic surgeons more frequently performed sCTR (67% and 63%, respectively). A total of 107 (65%) patients had sCTR. Fasciotomies for vascular/reperfusion injury were more likely to include sCTR (44%) compared with other mechanisms. If not performed simultaneously, 11 (19%) required delayed CTR at a median of 42 days. ACS secondary to fracture had the highest rate of delayed CTR (35%), and the necessity of late CTR for fractures was not supported by the logistic regression model. Residual hand paresthesias were less frequent in the sCTR group (6.5% vs 20%). Overall complication rates were similar in both groups (63% sCTR vs 70% without sCTR). CONCLUSION: When sCTR is excluded during forearm fasciotomy, 19% of patients required delayed CTR. This rate was higher (35%) when ACS was associated with fractures. Simultaneous CTR with forearm fasciotomy may decrease the incidence of residual hand paresthesias and the need for a delayed CTR. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognosis IV.

Exogenous Peptide Injection Causing Medical Thigh Compartment Syndrome.

BACKGROUND: Acute 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 REPORT: We 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.

Primary closure of fasciotomies has a reduced complication rate following compartment syndrome in the paediatric population.

PURPOSE: Currently no guidance exists within the literature regarding diagnostic criteria or the long-term outcomes for paediatric patients with acute compartment syndrome (ACS). We conducted a retrospective cohort study reviewing all cases of paediatric ACS managed at a single tertiary referral centre with the aim of characterising the factors responsible for the eventual outcomes. METHODS: The patient cohort was identified retrospectively by interrogating the hospital coding system for all paediatric patients between January 2014 and November 2022. The electronic emergency department, inpatient and operative notes as well as clinic letters for each patient were reviewed and data collected regarding presentation, associated injuries, management and subsequent complications plus length of follow-up. The data was analysed to determine if differences in presentation or management affected long term outcome. RESULTS: The final cohort consisted of 34 patients with a mean age of ten years at the time of presentation. The mean time from presentation to fasciotomy was 27.6 h (range 3.0 - 66.6). There was an overall complication rate of 37.5% with a mean follow-up period of 21 months. Patients who had direct closure of their fasciotomy wounds had a significantly lower complications rate and fewer operations compared to those who healed via other wound coverage methods or secondary intention (p < 0.05). CONCLUSIONS: Significantly higher complication rates were observed in patients who were unable to have direct wound closure following emergency fasciotomy. This information may be utilised to rationalise long term treatment plans and in counselling of patients and parents.

The impact of fasciotomy on inpatient outcomes in lower leg fracture management.

BACKGROUND: While lower extremity fractures are common injuries, concomitant compartment syndrome can lead to significant implications and surgical release (fasciotomy) is essential. The aim of this study was to identify potential predictors of compartment release and risk factors related to complications. Using a large nationwide cohort, this study compared patients suffering from lower extremity fractures with and without compartment syndrome during their primary in-hospital stay following trauma. METHODS: A retrospective analysis was conducted using the prospective surgical registry of the working group for quality assurance in surgery in Switzerland, which collects data from nearly 85% of all institutions involved in trauma surgery. Inclusion criteria Patients who underwent surgical treatment for tibia and/or fibula fractures between January 2012 and December 2022 were included in the study. Statistics Statistical analysis was performed using Chi-square, Fisher's exact test, and t test. Furthermore, a regression analysis was conducted to determine the independent risk factors for fasciotomy and related complications. In the present study, a p value less than 0.001 was determined to indicate statistical significance due to the large sample size. RESULTS: The total number of cases analyzed was 1784, of which 98 underwent fasciotomies and 1686 did not undergo the procedure. Patients with fasciotomies were identified as significantly younger (39 vs. 43 years old) and mostly male (85% vs. 64%), with a significantly higher American Society of Anesthesiologists (ASA) score (ASA III 10% vs. 6%) and significantly more comorbidities (30% vs. 20%). These patients had significantly longer duration of surgeries (136 vs. 102 min). Furthermore, the total number of surgical interventions, the rate of antibiotic treatment, and related complications were significantly higher in the fasciotomy group. Sex, age, comorbidities, and fracture type (both bones fractured) were identified as relevant predictors for fasciotomy, while ASA class was the only predictor for in-hospital complications. Outcomes Patients who underwent fasciotomy had a significantly longer hospital stay (18 vs. 9 days) and a higher complication rate (42% vs. 6%) compared to those without fasciotomy. While fasciotomy may have played a role, other factors such as variations in patient characteristics and injury mechanisms may also contribute. Additionally, in-house mortality was found to be 0.17%, with no patient death recorded for the fasciotomy group. CONCLUSIONS: Fasciotomy is vital. The knowledge about the further course is, however, helpful in resource allocation. We found significant differences between patients with and without fasciotomy in terms of age, sex, complication rate, length of stay, comorbidities, duration of operations, and use of antibiotics during their primary in-hospital stay. While the severity of the underlying trauma could not be modulated, awareness of the most relevant predictors for fasciotomy and related complications might help mitigate severe consequences and avoid adverse outcomes.

Gluteal compartment syndrome: who is most at risk?

PURPOSE: Gluteal compartment syndrome (GCS) is a rare but devastating condition with a paucity of literature to help guide diagnosis and management. This study aims to identify and describe the risk factors and patient characteristics associated with GCS to facilitate early diagnosis. METHODS: This is a retrospective case series of patients undergoing gluteal compartment release between 2015 and 2022 at an academic Level I trauma center. Chart reviews were performed to extract data on patient demographics, presenting symptoms, risk factors, operative findings, and postoperative outcomes. RESULTS: 14 cases of GCS were identified. 12 (85.7%) were male, with a mean age of 39.4 ± 13 years and a mean BMI of 25.1 ± 4.1 kg/m2. 12 (85.7%) patients did not present as traumas and only 3 had ≥ 1 fracture. 9 patients reported drug use. Hemoglobin (Hgb) (11.7 ± 4 g/dL) was generally low (5 had Hgb < 10 g/dL). Creatine kinase (49,617 ± 60,068 units/L) was consistently elevated in all cases, and lactate (2.8 ± 1.6 mmol/L) was elevated in 9. 13 had non-viable muscle requiring debridement. Postoperatively, the mean ICU length of stay was 12 ± 23 days. 2 patients died during admission and all remaining patients required discharge to rehabilitation facilities. CONCLUSION: GCS is more likely to present in a young to middle-aged, otherwise healthy, male using drugs who is either found down or experienced an iatrogenic injury. Recognizing that GCS is different from that of the leg, in terms of etiology, may help avoid delays in diagnosis and treatment.

Suprapatellar tibial fracture nailing is associated with lower rate for acute compartment syndrome and the need for fasciotomy compared with the infrapatellar approach.

BACKGROUND: Intramedullary tibial nailing (IMN) is the gold standard for stabilizing tibial shaft fractures. IMN can be performed through an infra- or suprapatellar approach. PURPOSE: The aim of this study is to compare the rate of fasciotomies for acute compartment syndrome between infra- and suprapatellar approaches. METHODS: A total of 614 consecutive patients who were treated with IMN for tibial fracture between October 2007 and February 2020 were included in the study. The approach used for IMN was determined by the operating surgeon. Infrapatellar IMN was performed with the knee in deep flexion position, with or without calcaneal traction. Suprapatellar IMN was performed in straight or semiflexed position. The diagnosis of compartment syndrome was based on clinical analysis, but for some patients, a continuous compartment pressure measurement was used. The primary outcome was the rate of peri- and postoperative compartment syndrome treated with fasciotomies. RESULTS: The study sample included 513 patients treated with infrapatellar IMN and 101 patients treated with suprapatellar IMN technique. The mean age of the patients was 44.7 years (infrapatellar technique) and 48.4 years (suprapatellar technique). High energy trauma was seen in 138 (27%) patients treated with infrapatellar technique and in 39 (39%) patients treated with suprapatellar technique. In the suprapatellar group (n = 101), there were no cases of peri- or postoperative compartment syndrome treated with fasciotomies. In the infrapatellar group (n = 513), the need for fasciotomies was stated in 67 patients, 31 patients (6.0%) perioperatively and in 36 patients (7.0%) postoperatively. The rate of fasciotomies (0/101 versus 67/513 cases) differed significantly (p < 0.001). There were no significant differences in the fracture morphology or patient demographics between the study groups. CONCLUSIONS: The suprapatellar technique is recommended over the infrapatellar approach in the treatment of tibial shaft fractures. The rate of peri- and postoperative compartment syndrome and the need for fasciotomies was significantly lower with the suprapatellar technique. The major cause of increased rate of peri- or postoperative acute compartment syndrome with infrapatellar IMN technique is presumably associated with the positioning of the patient during the operation.

Evaluation of musculoskeletal system injuries after the 2023 Kahramanmaras Turkey earthquakes: Our single-center experience.

INTRODUCTION: This study aimed to retrospectively analyze patients who presented to the orthopedic and traumatology clinic following the 2023 Kahramanmaras earthquakes. PATIENTS AND METHODS: Over a week after the earthquakes, two hundred and sixty patients were consulted at our clinic. Demographic data of the patients, duration of being under the rubble, fracture locations, types of surgeries performed, number of surgical sessions attended by individuals, and early mortality rate within one month were determined. RESULTS: The mean age of the patients was 40.2 ± 22.4 years. One hundred thirty-eight (53.1%) were female, and 122 (46.9%) were male. The average duration of being under the rubble was determined as 27.1 ± 28.0 hours. Sixteen patients died within one month after the earthquake. The one-month mortality rate among patients with orthopedic injuries was 6.15%. Forty-seven fasciotomies were performed in 35 patients, and 22 amputations were performed in 19 patients. The most injured region was the lower extremity (78 cases, 40%). The ratio of external and internal fixation in extremity fractures was 22%. CONCLUSIONS: The management of musculoskeletal injuries can be successful with proper triage and treatment plans. Decisions regarding fasciotomy and amputation in patients with crush syndrome following an earthquake should be individualized. Implant sets should be planned accordingly, especially considering the higher occurrence of lower extremity injuries.

Efficacy of the shoelace technique for extremity fasciotomy wounds due to compartment syndrome.

BACKGROUND: The shoelace technique for compartment syndrome allows application of sustained tightening tension to an entire wound and intermittent tightening of the shoelace without requiring its replacement or anesthesia. We retrospectively evaluated the usefulness of the shoelace technique in the management of extremity fasciotomy wounds before and after its introduction in our institution. METHODS: We targeted 25 patients who were diagnosed as having compartment syndrome and underwent extremity fasciotomy at our hospital from April 2012 to December 2021. The N group, comprising 12 patients treated without the shoelace technique, and the S group, comprising 13 patients treated with the shoelace technique, were compared retrospectively for each outcome. RESULTS: There were no significant differences between the two groups in patient background. Compared with the N group patients, all of the S group patients avoided skin grafting (S group: n = 0, 0%; N group: n = 6, 50.0%; p < 0.01). However, there was no significant difference in the number of days to final wound closure (S group: 39.5 [IQR 24.3-58.0] days; N group: 24.0 [IQR 18.5-31.0] days, p = 0.06). CONCLUSIONS: We considered the shoelace technique to be a useful wound closure method for fasciotomy wounds caused by compartment syndrome because it can significantly reduce the need for skin grafting and tends to shorten the wound closure period.

Contemporary management and time to revascularization in upper extremity arterial injury.

INTRODUCTION: Upper extremity arterial injury is associated with significant morbidity and mortality for trauma patients, but there is a paucity of data to guide the clinician in the management of these injuries. The goals of this review were to characterize the demographics, presentation, clinical management, and outcomes, and to evaluate how time to intervention associates with outcomes in trauma patients with upper extremity vascular injuries. METHODS: The National Trauma Data Bank (NTDB) Research Data Set for the years 2007-2016 was queried in order to identify adult patients (age ≥ 18) with an upper extremity arterial injury. Patients with brachiocephalic, subclavian, axillary, or brachial artery injury using the 1998 and 2005 versions of the Abbreviated Injury Scale were included. Patients with non-survivable injuries to the brain, traumatic amputation, or other major arterial injuries to the torso or lower extremities were excluded. RESULTS: The data from 7908 patients with upper extremity arterial injuries was reviewed. Of those, 5407 (68.4%) underwent repair of the injured artery. The median Injury Severity Score (ISS) was 10 (IQR = 7-18), and 7.7% of patients had a severe ISS (≥ 25). Median time to repair was 120 min (IQR = 60-240 min). Management was open repair in 52.3%, endovascular repair in 7.3%, and combined open and endovascular repairs in 8.8%; amputation occurred in 1.8% and non-operative management was used in 31.6% of patients. Blunt mechanism of injury, crush injury, concomitant fractures/dislocations, and nerve injuries were associated with amputation, whereas simultaneous venous injury was not. There was a significant decrease in the rate of amputation when patients undergoing surgical revascularization did so within 90 min of injury (P = 0.007). CONCLUSION: Injuries to arteries of the upper extremity are managed with open repair, endovascular repair, and, rarely, amputation. Expeditious transport to the operating room for revascularization is the key for limb salvage.

Upper Extremity Crotalid Envenomation: A Review of Incidence and Recent Trends in Management of Snakebites.

PURPOSE: The goal of this study was to evaluate the recent trends in the management of upper extremity Crotalid envenomation in the state of Georgia, United States. METHODS: A retrospective review of the Georgia Poison Center database looking at the reported snakebites to the upper extremity between 2015 and 2020 was performed. Patient demographics, timing and location of injury, severity of envenomation, treatment, including use of antivenin and surgical intervention, and reported complications related to the use of antivenin was extracted. RESULTS: A retrospective review of snakebites between 2015 and 2020 showed 2408 snakebite cases with a mean patient age of 37.4 years. Males incurred 62.8% of all bites. The highest incidence was in summer 52.5%, and between the hours of 5 PM to midnight 57.2%. Overall, 1010 (41.9%) of all bites were categorized as venomous snakebites (55.6% copperhead, 20% rattlesnake, 2.4% cottonmouth, and 22% miscellaneous [including 3 Elapid envenomations] or unidentified. The total number of venomous bites to the upper extremity was 575 (56.9%) and 567 patients received antivenin. Envenomation severity was mild in 29%, moderate in 45%, severe in 10%, and undetermined in 16% of cases. Crotalidae polyvalent immune Fab (Ovine) was the main antivenin used, with overall mean initial therapy dose of 6.2 vials and 59% of patients receiving maintenance therapy. Three patients (0.5%) had a severe anaphylactic reaction to antivenin requiring cessation of therapy. Seven patients had acute compartment syndrome of the upper extremity requiring fasciotomy (3 copperhead, 2 rattlesnake, and 2 unidentified). There was no reported mortality during this period. CONCLUSIONS: Hand surgeons should be familiar with the management of upper extremity Crotalid envenomation. Antivenin remains the main treatment for symptomatic patients. Crotalid snakebites rarely require operative intervention. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

Collagenase Treatment Versus Needle Fasciotomy for Single-Digit Dupuytren Contractures: A Meta-Analysis of Randomized Controlled Trials.

PURPOSE: The objective of this systematic review and meta-analysis was to synthesize the available randomized controlled trial data comparing needle fasciotomy and collagenase treatment for single-digit Dupuytren contractures with a minimum of 3-year follow-up and determine whether one treatment is superior regarding contracture correction and functional outcomes. METHODS: A systematic review and meta-analysis was conducted by searching four databases for randomized controlled trials investigating the single-digit treatment outcomes for Dupuytren contracture comparing collagenase treatment and needle fasciotomy with a minimum of 3-year follow-up. The risk of bias of included studies was assessed using the Cochrane risk-of-bias tool. A meta-analysis was performed using a random effects model in anticipation of unobserved heterogeneity. The primary outcome measure was contracture recurrence. Secondary outcome measures included final fixed flexion contracture (FFC), Quick Disabilities of Arm, Shoulder and Hand (QuickDASH) scores, and Unité Rhumatologique des Affections de la Main (URAM) scores. RESULTS: After screening 264 articles, 4 randomized clinical trials were eligible for final inclusion. One trial had a high risk of bias, and two trials had some concern for bias. The final meta-analysis included 347 patients, 169 who underwent collagenase treatment and 178 who underwent needle fasciotomy. No significant differences were noted between the groups in contracture recurrence, FFC, and URAM scores. The pooled data showed a higher QuickDASH score in the collagenase treatment group compared with the needle fasciotomy group, but the observed difference was less than what would be expected to be clinically relevant. CONCLUSIONS: Needle fasciotomy and collagenase treatment have similar outcomes with regards to contracture recurrence, final FFC, QuickDASH scores, and URAM scores for the single-digit treatment for Dupuytren contracture at a minimum of 3-year follow-up. Relevant factors that may be considered during the shared decision-making process for treatment selection include surgeon and patient preferences, costs of treatment, and the disparate complication profiles of these two treatments. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

Neonatal Limb Compartment Syndrome: A Comprehensive Review.

PURPOSE: Neonatal limb compartment syndrome (NLCS) is a rare and potentially limb-threatening condition defined as an increased pressure within a confined limb compartment. Clinicians may fail to distinguish NLCS from other mimicking conditions. Misdiagnosis is possible due to a low index of suspicion for this condition, which may delay appropriate and urgent treatment. A comprehensive review of the available literature was performed to explore common themes in NLCS and identify gaps in the evidence to guide future studies. METHODS: A literature search was conducted in PubMed, Scopus, and Google Scholar electronic databases to identify original articles and reviews in English or French. Studies were selected by two independent reviewers who extracted descriptive data including the delivery history and complications, the timing of diagnosis, the location of the lesion, and the management strategy. RESULTS: A total of 43 reports describing 86 cases of neonatal compartment syndrome were published between 1980 and 2021. The male-to-female ratio was 6:7. Compartment syndrome was mainly located in the upper extremity (95.3%). Clinical features including swelling (41%), sentinel skin lesion (94.2%), extremity cyanosis (89.5%), and necrotic fingers (7%) were observed. The treatment strategy was either surgical decompression (32.6%) or nonsurgical management (68.6%). Sequelae occurred at a rate of 16.6%, 81.3%, and 75.9% after early fasciotomy (< 24 hours), late fasciotomy, and nonsurgical management, respectively. CONCLUSIONS: Sentinel skin lesions and flaccid paralysis are the most observed clinical features and represent key clues for diagnosis. Neither radiography, Doppler ultrasound, nor magnetic resonance imaging has demonstrated any advantage in guiding the appropriate management of NLCS and may delay appropriate treatment. Despite nonsurgical management and late fasciotomy (> 24 hours) being the most described treatments, the lowest rate of sequelae was observed when decompression was performed within the first 24 hours. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic V.

Minimally invasive fasciotomy for symptomatic tibialis anterior muscle hernia.

BACKGROUND: Symptomatic muscle herniae are an uncommon cause of chronic exercise induced leg pain. The most common site for muscle hernia is the tibialis anterior muscle. This study evaluates the outcome of a minimal incision fasciotomy in patients with a symptomatic muscle hernia of the tibialis anterior muscle, and their return to normal daily activities including sport. METHODS: The study reports mid-term results in a series of 22 consecutive patients (17 males and 5 females, median age: 22 years) with a unilateral tibialis anterior MH who had undergone minimally invasive fasciotomy between 2008 and 2019. Clinical outcomes were assessed with SF-36 and European Quality of Life-5 Dimensions scale (EQ-5D). The ability to participate in sport before and after surgery, and the time to return to training (RTT) and to sport (RTS) were recorded. RESULTS: At a median follow up after surgery of 23 months, both questionnaires showed a statistically significant improvement (P < 0.005). At the latest follow up, 16 of patients (73%) had returned to pre-injury or higher levels of sport/activity. The median time to return to training and to return to sport was 7 and 11 weeks respectively. No severe complications and no recurrence of symptoms were recorded. CONCLUSION: Minimally invasive fasciotomy is effective and safe for patients suffering from muscle hernia of the tibialis anterior muscle with good results in the mid-term. LEVEL OF EVIDENCE: IV.

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

PURPOSE: 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. METHODS: 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. RESULTS: The overall incidence of lower legs and forearms ACS 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). CONCLUSIONS: 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.

Surgical treatment options for plantar fasciitis and their effectiveness: a systematic review and network meta-analysis.

BACKGROUND: To date, there are no systematic reviews on the utility of surgical management for plantar fasciitis to guide best practice. This review aimed to evaluate the operative options for plantar fasciitis and their effectiveness. METHODS: A systematic review and network meta-analysis were carried out in accordance with PRISMA guidelines. A search strategy was conducted on the MEDLINE, EMBASE, and Cochrane databases. Quality was assessed using the ROBINS-I tool. RESULTS: 17 studies involving 865 patients were included. Surgical options considered were open and endoscopic plantar fasciotomy, gastrocnemius release, radiofrequency microtenotomy and dry needling. All interventions resulted in improvement in VAS and AOFAS scores. No major complications were seen from any treatment modality. CONCLUSIONS: Surgical interventions are effective in providing short- to medium-term symptomatic relief for plantar fasciitis refractory to non-operative management. Current evidence is equivocal regarding treatment choice. Further large randomised studies are required to establish long-term outcomes and a management algorithm. LEVEL OF EVIDENCE: Level III.

Compartment Syndrome after Crotalid Envenomation in the United States: A Review of the North American Snakebite Registry from 2013 to 2021 on Behalf of the ToxIC Snakebite Study Group.

INTRODUCTION: Compartment syndrome (CS) is a rare but serious complication after crotalid envenomation in the United States. Few data are available regarding the epidemiology and management of these cases. Significant controversy and misunderstanding over best practices, including measurement of compartment pressures and use of fasciotomy, exist for this syndrome. This study aims to describe presentation and management of suspected CS cases after native snakebite reported to the North American Snakebite Registry (NASBR). METHODS: This is an analysis of snakebite cases reported to the Toxicology Investigators Consortium NASBR between January 1, 2013 and December 31, 2021. Cases of native snakebite with documented concern for CS were included. RESULTS: Over an 8-y period, 22 cases of suspected CS were identified, representing 1% of all cases reported to the NASBR. Fasciotomies were performed in 41% (n=9) of these cases, most commonly to the upper extremity (67%, n=6). In cases of suspected CS, intracompartmental pressures (ICPs) were rarely measured (23%, n=5) and fasciotomies were performed without measurement of ICPs frequently (56%, n=5). In 1 case, ICPs were measured and found to be low (8 mm Hg) and fasciotomy was avoided. CONCLUSIONS: Measurement of compartment pressures in cases of suspected CS was uncommon in cases reported to the NASBR. Fasciotomy was commonly performed without measurement of compartment pressures.
