Compartment Syndrome Following Snake Envenomation in the United States: A Scoping Review of the Clinical Literature.

Local tissue destruction following envenomation from North American snakes, particularly those within the Crotalinae subfamily, has the potential to progress to compartment syndrome. The pathophysiology of venom-induced compartment syndrome (VICS) is a debated topic and is distinct from trauma/reperfusion-induced compartment syndrome. Heterogeneity exists in the treatment practices of VICS, particularly regarding the decision to progress to fasciotomy. Associations with functional outcomes and evolution in clinical practice since the introduction of Crotalidae polyvalent immune Fab (FabAV) have not been well defined. Our goal was to identify the potential gaps in the literature regarding this phenomenon, as well as illuminate salient themes in the clinical characteristics and treatment practices of VICS. We conducted this systematic scoping-style review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Records were included if they contained data surrounding the envenomation and hospital course of one or more patients who were envenomated by a snake species native to North America and were diagnosed with compartment syndrome from 1980-2020. We included 19 papers: 10 single- or two-patient case reports encompassing 12 patients, and nine chart reviews providing summary statistics of the included patients. In case reports, the median compartment pressure when reported was 60 millimeters of mercury (interquartile range 55-68), 66% underwent fasciotomy, and functional outcomes varied. Use of antivenom appeared to be more liberal with FabAV than the earlier antivenin Crotalidae polyvalent. Rapid progression of swelling was the most commonly reported symptom. Among the included retrospective chart reviews, important data such as compartment pressures, consistent laboratory values, and snake species was inconsistently reported. Venom-induced compartment syndrome is relatively rare. Existing papers generally describe good outcomes even in the absence of surgical management. Significant gaps in the literature regarding antivenom dosing practices, serial compartment pressure measurements, and functional outcomes highlight the need for prospective studies and consistent standardized reporting.

Fasciotomy following North American pit viper envenomation in Texas 2004–2021

Introduction North American pit viper envenomation occurs over 4,000 times annually in the United States, with polyvalent Fab antivenom being the primary treatment. Fasciotomy is occasionally performed due to concerns about compartment syndrome. We utilized our direct access to Texas Poison Center Network data to create a new snakebite abstraction form and database on relevant available information between 2004 and 2021 and to identify, describe, and estimate the incidence of fasciotomy following pit viper envenomation in Texas. Methods We searched the Texas Poison Center Network database for cases during 2004–2021 using keywords such as fasciotomy, surgery, compartment pressure, and compartment syndrome. Descriptive statistics summarized the data. Results Of 16,911 reported envenomations, 0.69 percent involved fasciotomies (n = 117). Most common bite sites were digits/hands and lower extremities. Patients who underwent fasciotomy were typically male, aged 20–59, and 10 years younger than the total snakebite population. Only 6 percent of reported compartment syndrome cases had a compartment pressure measurement. Antivenom was administered in 101 (86.3 percent) cases, 92 (91.1 percent) of which received only Fab antivenom product. Patients with bites from rattlesnakes (47.9 percent) were associated with most fasciotomies Discussion Our findings suggest a potential increase in snakebite exposures, accompanied by a decrease in fasciotomies. Overall, copperheads constituted the majority of snakebites, but most fasciotomies were from rattlesnake envenomations (47.9 percent). In this cohort, compartment syndrome diagnosis and decisions regarding fasciotomy were primarily based on clinical evaluation/surgeon expertise without compartment pressure measurements. Despite the efficacy of antivenom, only 86.3 percent of patients in our study received antivenom. Conclusions Fasciotomy after North American pit viper envenomation in Texas is uncommon (0.69 percent) and has decreased over time, possibly due to increased antivenom use or surgeon comfort with nonsurgical management.

Updates in Diagnosis and Management of Forearm Compartment Syndrome

In children, compartment syndrome of the forearm often arises from supracondylar fractures, whereas in adults, distal radius fractures are the predominant cause. In 48% of instances, diagnosis was based exclusively on clinical assessment, while in the remaining 52% of cases, a combination of intracompartmental pressure measurement and clinical assessment was used. Several methods, including wick catheters, slit catheters, the Whitesides method, and the Stryker compartment pressure measurement device, were employed to measure intracompartmental pressure. The treatment approach of choice was fasciotomy, with a preference rate of 73%. Out of all the patients that needed wound management, postfasciotomy skin grafting was essential in 61% of them, while secondary closure was done in 39% of cases. The most prevalent consequence, observed in 21% of patients, was neurological impairment.

A hybrid 3D-printed model for lower extremity compartment syndrome simulation

BackgroundCompartment syndrome is a medical emergency. It should be diagnosed promptly, and therapeutic measures should be taken to avoid limb ischemia. Measurement of compartment pressure is extremely important. ModelKnowledge about compartments and familiarity with the pressure monitoring device are important to diagnose acute compartment syndrome properly. Simulations provide an opportunity to learn the device and practice the procedure. Given their lower cost and the possibility of frequent reproduction, simulations using 3D-printed material are gaining popularity. We propose a simple low-fidelity model using a silicone-based lower leg soft tissue, 3D-printed tibia and fibula, Foley catheter, and syringes. ConclusionThis low-fidelity simulator helps to improve procedural skills and retention through repeated practice.

Practical Review on the Contemporary Diagnosis and Management of Compartment Syndrome.

Acute compartment syndrome (ACS) is a limb-threatening pathology that necessitates early detection and management. The diagnosis of ACS is often made by physical examination alone; however, supplemental methods such as compartment pressure measurement, infrared spectroscopy, and ultrasound can provide additional information that support decision-making. This practical review aims to incorporate and summarize recent studies to provide evidence-based approaches to compartment syndrome for both resource-rich and -poor settings among several patient populations.

Evaluating the Need for Simultaneous Carpal Tunnel Release With Forearm Fasciotomy

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. 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. 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). 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. Prognosis IV.

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

BackgroundIntramedullary tibial nailing (IMN) is the gold standard for stabilizing tibial shaft fractures. IMN can be performed through an infra- or suprapatellar approach.PurposeThe aim of this study is to compare the rate of fasciotomies for acute compartment syndrome between infra- and suprapatellar approaches.MethodsA 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.ResultsThe 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.ConclusionsThe 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.Level of evidence3.

An overview of exertional leg pain in the athlete

Exertional leg pain is a common problem in the athletic population, presenting with a constellation of similar symptoms. Delayed or incorrect diagnosis and treatment may result in significant morbidity and avoidable cessation of activity. Multiple causes such as chronic exertional compartment syndrome (CECS), medial tibial stress syndrome (MTSS), nerve or vascular entrapment syndromes may be responsible. A thorough history and focused clinical examination is mandated, and may yield clues as to the definitive diagnosis. Investigative adjuncts include imaging, compartment pressure measurement and electrodiagnostic studies. Whilst specific management depends on the underlying cause, the mainstay of initial management is activity modification, with surgery reserved for those who fail to respond to conservative measures.

Chronic Exertional Compartment Syndrome in Athletes: An Overview of the Current Literature.

Chronic exertional compartment syndrome is an incapacitating condition that primarily affects athletes and individuals with high activity levels. The exact etiology of the condition is unknown to date, but multiple factors play a role in its occurrence. The clinical presentation includes pain, tightness, muscle weakness, paresthesia, and cramps. Common tools utilized during the diagnostic approach include intramuscular compartment pressure measurement, advanced imaging to exclude other disorder entities, near-infrared spectrometry, and shear wave elastography, with the clinical diagnosis being the gold standard. Management includes both conservative and surgical options. Conservative treatment includes gait re-training and botulinum toxin injections. Further, the operative treatment has variable approaches and may be combined with conservative modalities. This article reviews the literature on chronic exertional compartment syndrome and elucidates future recommendations.

Compartment Syndrome following Intramedullary Nail Fixation in Closed Tibial Shaft Fractures.

Compartment syndrome complicating intramedullary nailing of closed tibia fractures has been described as early as the 1980s, but currently remains less described in literature compared to compartment syndrome directly following trauma. This study aims to review this potentially disabling complication and highlight the importance of timely diagnosis and management of compartment syndrome following fracture fixation, not just after fracture itself, via a review of three cases. A retrospective study of a series of three cases was conducted. The type of fracture, wait time to fixation, surgery duration, reaming, size of nail implant used, tourniquet time, and surgical technique were recorded. Time to diagnosis of compartment syndrome, compartment pressure if available, extent of muscle necrosis, reconstructive procedures performed, and post-operative complications were analysed. The three cases following high-energy trauma from road traffic accidents presented from January to May 2010. Compartment syndrome was diagnosed clinically for all cases, between one to six days post-operatively and supported by elevated compartment pressure measurements in two of the three cases. This study advocates thorough clinical monitoring and maintaining strong clinical suspicion of compartment syndrome in patients even after intramedullary nail fixation of tibial shaft fractures to achieve timely limb-salvaging intervention. While intercompartmental pressure can be used to aid in diagnosis, we do not advise using it in isolation to diagnose compartment syndrome. Tendon transfer improves functional mobility and provides a good result in patients with severe muscle damage, while skin grafting sufficient in patients with minimal muscle damage.

Measurement of the gluteal compartment pressures: A cadaveric study describing safety and reproducibility of two methods

IntroductionGluteal compartment syndrome is an uncommon entity and physicians may use intracompartmental pressure measurements for confirmation of the clinical diagnosis, or in cases where the physical exam is indeterminate. However, there is a paucity of literature describing a safe and reproducible technique to measure gluteal intracompartmental pressures during the diagnosis of gluteal compartment syndrome. The purpose of this cadaveric study is to evaluate the sole previous technique described in the literature to measure gluteal intracompartmental pressures and provide a modified technique which can be safely and reliably utilized clinically. MethodsA cadaveric study with three phases was performed in 16 gluteal regions in 8 cadavers. In the first phase, the previously described technique was assessed. In the second phase, a modified set of techniques was created and evaluated. In the third phase, inter-user reliability of the modified set of techniques was assessed and calculated using Cohen's ĸ coefficient. In all three phases, methylene blue was injected through pressure monitoring needles into the gluteus maximus (GMax), gluteus medius/minimus (GMM), and the tensor fascia lata (TFL) compartments. Following dissection, rate of successful penetration into each targeted compartment and distance from the neurovascular structures was recorded. ResultsThe previously described set of techniques was found to be variable. The modified set of techniques was effective, successfully reaching the GMax, GMM, and TFL compartments in 100%, 100%, and 81% of attempts, respectively. Inter-user reliability was excellent (ĸ = 1) for the techniques to reach both the GMax and GMM compartments, and moderate (ĸ = 0.54) for the technique to reach the TFL compartment. Within the GMax, the pressure monitoring needle was at a mean of 5.4±0.6 cm, 4.1±0.7 cm, 6.4±0.5 cm from the sciatic nerve (SN), superior gluteal nerve (SGN), and inferior gluteal nerve (IGN), respectively. Within the GMM, the pressure monitoring needle was at a mean of 9.7±1.4 cm, 7.4±1.3 cm, 11.1±1.7 cm from the SN, SGN, and IGN, respectively. ConclusionThe modified set of techniques presented allows the three gluteal compartments to be safely and reproducibly reached to measure intracompartmental pressures during the diagnosis of gluteal compartment syndrome.

Chronic Exertional Compartment Syndrome of the Lower Extremity: Diagnosis and Surgical Treatment.

Chronic exertional compartment syndrome of the lower extremity is a condition that characteristically presents as recurrent anterior, posterior, and/or lateral lower-extremity pain on repetitive activity and physical exertion1. This condition is commonly seen in athletes, runners, and military personnel2. Open fasciotomy has been demonstrated to be a highly effective surgical treatment for patients with this condition who do not experience symptomatic relief after a thorough trial of nonoperative treatment3. Diagnostic compartment pressure management is achieved through direct insertion of a compartment-pressure-measuring device into the anterior, lateral, and posterior compartments of the lower extremity4. Surgical treatment of the anterior and lateral compartments with use of open fasciotomy employs longitudinal proximal and distal incisions that are made on the lateral surface of the leg approximately 3 finger-breadths distal and proximal to the fibular flare, respectively, and 3 finger-breadths lateral to the tibial crest. Surgical treatment of the posterior compartments with use of open fasciotomy employs a single, mid-shaft incision made approximately 2.5 cm medial to the tibial ridge. Dissection is carried down to the deep fascia at both sites, beginning at the distal operative site. Care is taken to avoid transection of the superficial peroneal nerve at the distal anterolateral incision and saphenous vein and nerve at the medial incision. Once down to the deep fascia, a scalpel is utilized to incise the fascia. Metzenbaum scissors are then employed under the incision, spreading the scissors while sliding them over the muscles proximally and distally to release the muscular attachments from the fascia as well as to release the fascia itself3. This process is repeated in the anterior, lateral, and superficial posterior compartments through the proximal and distal incisions. In the deep posterior compartment, the fascia is released from the tibial ridge with a large Cobb elevator. Closure is achieved with deep dermal and superficial sutures. Nonoperative alternatives have been reported to include nonpharmacological modalities such as walking modification and shoe inserts, pharmacological therapy with nonsteroidal anti-inflammatory drugs, and physical therapy targeted at conditioning the lower extremity5. Nonoperative intervention has been demonstrated to increase endurance in select patients; however, most patients must either stop the activity associated with the compartment syndrome altogether or proceed to surgery for complete resolution of symptoms5. There are a few surgical alternatives that differ in their utilization of minimally invasive approaches versus a direct open approach6; however, all existing surgical treatments of this condition involve physical release of the fascial compartment. Diagnostic compartment-pressure measurement is useful in confirming or ruling out the presence of this condition in patients with unclear symptoms4. Furthermore, diagnostic compartment-pressure management ensures accuracy in diagnosis and validates invasive treatment when patients desire surgical intervention. Surgical management of exertional compartment syndrome of the lower extremity is indicated in patients when nonoperative treatment has failed despite clinically notable symptoms and objectively elevated lower-extremity compartment pressures. Open fasciotomy has been postulated to prevent compression of local vasculature and effectively prevent ischemia; however, the definitive mechanism is unclear1. Surgical treatment of chronic exertional compartment syndrome with use of open fasciotomy is highly successful in the civilian population. One study showed excellent return to activity/sport in 15 of 16 patients (25 of 26 limbs; 96%), with patients often reporting no symptoms postoperatively3. Military personnel have been reported to experience satisfactory results, with another study showing positive subjective feedback in 35 (76%) of 46 patients on long-term follow-up; however, only 19 patients (41%) were able to return to full active duty postoperatively7. Balloting the fascial compartment with ∼1 cc of saline solution can be helpful in determining successful placement of the pressure-measuring device at the time of needle entry.Identifying the course of the superficial peroneal nerve via physical examination can help avoid iatrogenic injury to this important superficial structure during the dissection leading to the distal fasciotomy.Deep posterior compartment release with use of open fasciotomy may not provide symptomatic relief; patients who demonstrate elevation of pressures in this specific compartment should be counseled accordingly.

Atraumatic Bilateral Acute Compartment Syndrome of the Lower Legs: A Review of the Literature.

Bilateral acute compartment syndrome of the legs is a very rare presentation that requires emergency surgical intervention. Atraumatic bilateral cases are almost unheard of in medicine. There is currently no link between compartment syndrome and cognitive impairment or mental health.A systematic literature search was performed in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines using the following keywords in multiple databases: compartment syndrome, atraumatic, spontaneous, bilateral, both, lower leg, acute, compartmental pressure, and fasciotomy. Atraumatic, bilateral, acute, and confirmed compartment syndrome cases were included.In total, 33 cases of atraumatic bilateral acute compartment syndrome (ABACS) were identified, of those 72.7% of cases were males. A form of cognitive impairment was found in 66% of cases. The medical history of the cases included substance abuse (nine patients), mental health illness (seven patients), and hypothyroidism (four patients). Within the reports, there was evidence of a misdiagnosis or delayed management in 19 cases (57.6%). Creatinine kinase (CK) was measured in 28 cases with a mean CK of 110,893 IU/L. Compartment pressure measurements were used in only 12 cases. A total of 29 cases were managed with bilateral four-compartment fasciotomy.This review highlights that ABACS is a condition with high rates of misdiagnosis or delay in treatment. Associations found included patients with cognitive impairment on presentation, mental health conditions, substance misuse, and elevated levels of CK. In addition, this review demonstrates that this condition is less rare than previously thought with serious morbidity and mortality.

Evaluation of Clinical and Venous Blood Parameters as Surrogate Indicators in Assessing the Need for Fasciotomy in Lower Limb Compartment Syndrome.

Acute compartment syndrome in the lower limb, a surgical emergency, may cause ischemic damage to muscles and neurological deficits leading to loss of function of the limb which may even require amputation, thus drastically affecting the quality of life of a patient. Fasciotomy for decompression is suggested when the differential pressure in the compartment of the leg is ≤30 mm Hg. However, compartment pressure measurement is not always feasible. Surgeons often find themselves in a dilemma in deciding the right treatment option for the patient: fasciotomy or conservative management. Since there is no universally accepted reference standard for the diagnosis of acute compartment syndrome at present, there is a need for definitive diagnostic variables so as to not delay fasciotomy in patients who need it, as well as to avoid unnecessary fasciotomies, especially when compartment pressures cannot be measured. In this observational study including 71 patients, based on the compartment pressures of the affected limb, treatment was done either with fasciotomy or conservative approach, and various clinical and biochemical parameters were evaluated in between these two groups. Statistically significant difference was found in the venous blood gas parameters between patients managed conservatively and with fasciotomy (MANOVA, P = .001). The results revealed the association of lower venous blood bicarbonate levels (independent sample t test, P = .021) and the presence of paresthesia (Fisher exact test, P = .0016) with the fasciotomy group. Also, pain on passive stretching of the affected limb was found to be significantly associated with a delta pressure of ≤30 mm Hg in any compartment (Fisher exact test, P = .002). These variables may thus be used as an alternative to the measurement of compartment pressure to assess the requirement of fasciotomy.

A hospital based one year randomised controlled trial to determine optimum height of leg elevation in closed fractures of leg by invasive intra compartmental pressure monitoring

Introduction: Closed fractures of leg are common following RTA, which requires immobilization and leg elevation above heart level to reduce oedema formation and increase of compartment pressure leg elevation is routine in pre operative and post operative period to reduce intra compartment pressure whereas optimum height of elevation has not been standardized till now. Inadvertent elevation of leg decreases venous oedema whereas chances of muscle ischemia increases with prolonged and inappropriate elevation of leg. So determination of appropriate level of leg elevation above heart level by invasive method by white side’s method will help reduce muscle ischemia and discomfort to the patient. Purpose: To determine optimum height of leg elevation above heart level to reduce intra compartmental pressure.Methods: Patients at KLES Dr. Prabhakar Kore Hospital with closed fractures of leg. Anterior compartment pressure measured with Whiteside’s invasive method .Patients were randomly divided into two groups Group A: 15 cm of leg elevation and Group B:30 cm of leg elevationResults: In this study 60 patients with closed fractures of tibia were selected for intra compartmental pressure monitoring and randomised for different weights of leg elevation i.e., Group A 15 cm above heart level and Group B 30 cm above heart level. The mean age of leg fractures in our study was 40.1 years. Male subjects were 85% (mean = 53) and female were 17% (mean = 7) of total of 60 patients.The measurement of compartment pressure of normal leg was 9.4 ± 2.5 mm Hg. Pressure were measured within 5 cm of fracture site at 0 hr, 12 hr, 24 hr and 48 hr interval using Whiteside’s method. The mean values at 0 hr were 29.17 ± 5.95 mm Hg, at 12 hr interval it was 29.97 ± 5.46 mm Hg, at 24 hr interval it was 23.36 ± 3.8 mm Hg and at 48 hr interval it was in Group A. The mean values at 0 hr were 32 ± 7.8 mm Hg, at 12 hr interval it was 32.33 ±57.65 mm Hg, at 24 hr interval it was 26.48 ± 3.5 mm Hg and at 48 hr interval it was in 25.19 ± 2.56 mm Hg in Group B. In our study 5 patients out of 60 underwent fasciotomy. All patients had differential or delta pressure below 30 mm Hg before fasciotomy.Conclusion: Tibia fractures are commonest cause of compartment syndrome of leg. Whiteside’s method is a reliable and safe method of measuring intra compartment pressure when sophisticated methods are not available. Inappropriate levels of leg elevation causes muscle ischemia. Elevation of leg to 15 cm leads same clinical results as 30 cm with the advantage of avoiding muscle ischaemia. There is further need for evaluation of different heights of leg elevation and review about our practice of leg elevation.

Minimally invasive measurement of orbital compartment pressure and implications for orbital compartment syndrome: a pilot study.

Diagnosis of orbital compartment syndrome is mainly based on clinical findings, such as intraocular pressure and proptosis, which try to estimate the orbital compartment pressure. However, the reliability of these surrogates is unclear. Current techniques for the direct measurement of orbital compartment pressure are widely experimental and impractical in the clinical setting. Our aim was to explore the feasibility of minimally invasive needle manometry for direct measurement of orbital compartment pressure under reproducible conditions in an in vivo model of orbital congestion. We further sought to evaluate intraocular pressure and proptosis as indicators for elevated orbital compartment pressure. A total of 7 ml of mepivacaine 2% solution was injected into the orbital compartment in 20 patients undergoing cataract surgery under local anesthesia. A commercially available single-use manometer device was inserted between the syringe and the injection needle to measure the orbital compartment pressure for each milliliter of intraorbital volume increment. Additionally, intraocular pressure (subgroup A; n = 10) or axial globe position (subgroup B; n = 10) were measured. Needle manometry allowed for rapid and continuous measurement of orbital compartment pressure. Overall mean orbital compartment pressure increased from 2.5 mmHg pre- to 12.8 mmHg post-interventionally. Both, intraocular pressure (Spearman's correlation coefficient rs = 0.637, p < 0.0001) and proptosis (rs = 0.675, p < 0.0001) correlated strongly with the orbital compartment pressure. Needle manometry appears to be a feasible minimally invasive instrument to directly measure orbital compartment pressure, showing promises for a more routine application in managing orbital compartment syndrome. The results further suggest that both elevated intraocular pressure and proptosis are valuable indicators for orbital compartment syndrome.

Paravertebral compartment syndrome after exercise: a case report

BackgroundParavertebral compartment syndrome occurring without trauma is quite rare. We report a case of compartment syndrome that occurred after spinal exercises.Case presentationA 23-year-old Japanese rower developed severe back pain and was unable to move 1 day after performing exercises for the spinal muscles. Initial evaluation at a nearby hospital revealed hematuria and elevated creatine phosphokinase levels. He was transferred to our hospital, where magnetic resonance imaging revealed no hematoma but confirmed edema in the paravertebral muscles. The compartment pressure measurements were elevated bilaterally. Despite his pain being severe, his creatine phosphokinase levels were expected to peak and decline; his urine output was normal; and surgery was undesirable. Therefore, we opted for conservative management. The next day, the patient’s compartment pressure diminished, and his pain levels decreased to 2/10. After 5 days, he was able to walk without medication.ConclusionsWe present a rare case of compartment syndrome of the paravertebral muscles with good resolution following conservative management. We hope our case findings will help avoid unnecessary surgery in cases of paravertebral compartment syndrome.

Measurement of compartment pressure in closed tibia fracture using white side’s technique

Introduction: Tibia fractures account for 40% of acute compartment syndrome. Measurement of compartment pressure in high energy trauma, complex fractures, unconscious patient, poly trauma, severe soft tissue injury avoids morbidity and permanent disability by timely fasciotomy. Whiteside’s method of needle manometer technique is a accepted method of invasive technique of compartment syndrome measurement. Materials and Methods: Patients admitted in vydehi institute of medical science hospital with closed tibia fractures during Jan 2019 to Dec 2019 were included after consent. Anterior compartment of leg was chosen and site of measurement was 5 cm from fracture. Differential pressure was also recorded and cut off for fasciotomy was 30 mm Hg. Results: 60 patients with closed tibia fractures were included in the study. 5 patients underwent fasciotomy and all patients had delta pressure less than 30 mm Hg before fasciotomy. Conclusion: Whiteside’s technique is a safe, easily assembled, inexpensive method of intra compartment pressure measurement and differential pressure is a reliable guide for decision of fasciotomy compared absolute pressure.

Dichotomy in Fasciotomy: Practice Patterns Among Trauma/Acute Care Surgeons With Performing Fasciotomy With Peripheral Arterial Repair

Failure to perform adequate fasciotomy for a presumed or diagnosed compartment syndrome after revascularization of an acutely ischemic limb is a potential cause of preventable limb loss. When required, outcomes are best when fasciotomy is conducted with the initial vascular repair. Despite over 100 years of experience with fasciotomy, the actual indications for its performance among acute care and trauma surgeons performing vascular repairs are unclear. The hypothesis of this study was that there are many principles of fasciotomy that are uniformly accepted by surgeons and that consensus guidelines could be developed. A 20-question survey on fasciotomy practice patterns was distributed to trauma and acute care surgeons of a major surgical society which had approved distribution. The response to the survey was 160/1066 (15 %). 92.5% of respondents were fellowship trained in trauma and acute care surgery, and 74.9% had been in practice for fewer than 10 years. Most respondents (71.9%) stated that they would be influenced to perform a preliminary fasciotomy (fasciotomy conducted prior to planned exploration and arterial repair) based upon specific signs and symptoms consistent with compartment syndrome-including massive swelling (55.6%), elevated compartment pressures (52.5%), delay in transfer >6 hours (47.5%), or obvious distal ischemia (33.1%). 20.6% responded that they would conduct exploration and repair first, regardless of these considerations. Prophylactic fasciotomies (fasciotomy without overt signs of compartment syndrome) would be performed by respondents in the setting of the tense compartment (87.5%), ischemic time >6 hours (88.1%), measurement of elevated compartment pressures (66.9%), and in the setting of large volume resuscitation requirements (31.3%). 69.4% of respondents selectively measure compartment pressures, with nearly three-fourths utilizing a Stryker needle device (72.5%). The most common sequence of repairs following superficial femoral artery injury with a >6-hour limb ischemia was cited as the initial insertion of a shunt, followed by fasciotomy, then vein harvest, and finally interposition repair. While there is some general consensus on indications for fasciotomy, there is marked heterogeneity in surgeons' opinions on the precise indications in selected scenarios. This is particularly surprising in light of the long history with fasciotomy in association with major arterial repairs and strongly suggests the need for a consensus conference and/or meta-analysis to guide further care.

Post-exercise leg compartment pressure measurements in asymptomatic collegiate distance runners: a prospective study

Background: Chronic exertional compartment syndrome (CECS) is an uncommon cause of leg pain in running athletes. Post-exercise compartment pressure measurements are an invasive test that many clinicians use for making the diagnosis of CECS. We sought to determine if intracompartmental pressures in anterior leg compartments of asymptomatic collegiate distance runners meet established criteria for diagnosis of exertional compartment syndrome. Methods: Thirty collegiate running athletes underwent 1-minute post-exercise compartment pressure measurements of bilateral anterior leg compartments. Each was asked to run for 15 min at a moderately intense pace, and then underwent measurements performed at 1-minute postexertion with a needle manometer. Fifteen male and 15 female collegiate running athletes from age 18 to 23 yr (average 20.8 yr) underwent post-exercise compartment pressure testing of the legs. Results: Eleven (six men, five women) demonstrated 1-minute post-exercise compartment pressure measurements that met criteria for diagnosis of exertional compartment syndrome in at least one leg based on established criteria (&gt;30 mmHg). Of these 11, four demonstrated positive measurements bilaterally (two men, two women). Intracompartmental pressure measurements ranged from 16 mmHg to 88 mmHg (average 27.5 mmHg). Measurements of anterior leg compartments performed at 1-minute post-exercise were indicative of exertional compartment syndrome in more than one-third of the asymptomatic running athletes tested (11/30, 36.7%). Conclusions: Elevated anterior leg compartment pressures were prevalent in collegiate distance runners despite a lack of symptoms. Post-exercise compartment pressure measurements should be viewed only as an indicator of exertional compartment syndrome and not relied upon as a confirmatory test. Level of Evidence: Level IV.
