Contemporary outcomes of surgical decompression for functional popliteal entrapment syndrome.

BACKGROUND: Functional popliteal entrapment syndrome (FPES) is an under-recognized source of leg pain caused by dynamic compression of the popliteal vessels by surrounding musculature in the absence of anatomic abnormality. Late recognition and difficulty capturing this entity across imaging modalities can lead to significant morbidity in an often young and active patient population. Surgical outcomes and optimal diagnostic strategies remain uncertain. METHODS: We performed a retrospective cohort study of all patients undergoing surgical decompression for FPES at an academic medical center between 2018 and 2022. Preoperative symptoms, patient characteristics, imaging, operative details, and follow-up were captured. The primary outcome was symptomatic improvement at last clinic visit. Secondary outcomes included symptomatic improvement at 6 months and postoperative complications. RESULTS: A total of 24 extremities (16 patients) were included. The mean ± standard deviation age was 23.3 ± 6.4 years and 75.0% of patients were female. The median symptom duration before decompression was 27 months (interquartile range, 10.7-74.6 months). Preoperative symptom severity in the affected extremity was as follows: 33.3% limited from peak exercise, 25% unable to exercise, and 41.7% with debilitating symptoms that affected activities of daily living. Preoperative imaging with provocative maneuvers included duplex ultrasound (87.5%), magnetic resonance angiography (100%), and digital subtraction angiography (100%). Using digital subtraction angiography as the gold standard, the sensitivity for detection of FPES was 85.7% for duplex examination and 58.3% for magnetic resonance angiography. The median follow-up was 451 days (interquartile range, 281-635 days). Most patients demonstrated durable improvement in the affected extremity, with 29.2% realizing complete resolution of symptoms and 37.5% reporting symptomatic improvement at last clinic visit for a total of 66.7%; 20.8% had initial improvement, but developed recurrent symptoms and were found to have elevated compartment pressures consistent with chronic exertional compartment syndrome and were treated with formal fasciotomy. Repeat decompression was required in one extremity (4.2%) owing to recurrent symptoms. Two patients (8.3%) had minimal or no improvement in their affected extremity and workup for the cause of continued discomfort was ongoing. CONCLUSIONS: Delays in diagnosis of FPES are common. Provocative maneuvers until replication of symptoms across multiple imaging modalities may be necessary to reliably identify the disease process. Surgical decompression improved or completely resolved symptoms in two-thirds of extremities. Treating physicians should maintain suspicion for comorbid chronic exertional compartment syndrome, especially if symptoms recur or persist after decompression.

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.

Three-Month Complication Rate of Ultrasound-Guided Soft Tissue Surgical Procedures Across Six Sports Medicine Clinics.

OBJECTIVES: To 1) determine the types and frequency of complications within 3 months following ultrasound-guided surgical procedures, and 2) identify any patient demographics, co-morbidities, or procedural characteristics that were associated with an increased risk of complications. METHODS: A retrospective chart review was performed at six Sports Medicine clinics across the United States. The Clavien-Dindo classification was used to categorize procedural complications on a 5-point scale from 1, representing any deviation in post-procedure care without requiring pharmacological or invasive treatment to 5, representing death. Generalized Estimating Equations for binomial outcomes with a logit link were used to estimate the overall and procedure-specific 3-month complication rates. RESULTS: Among 1902 patients, 8.1% (n = 154) had diabetes and 6.3% (n = 119) were current smokers. The analysis included 2,369 procedures, which were performed in either the upper extremity (44.1%, n = 1045) or lower extremity (55.2%, n = 1308) regions. The most common procedure was ultrasound-guided tenotomy (69.9%, n = 1655). Additional procedures included, trigger finger release (13.1%, n = 310), tendon scraping (8.0%, n = 189), carpal tunnel release (5.4%, n = 128), soft tissue release (2.1%, n = 50), and compartment fasciotomy (1.6%, n = 37). Overall, there was a complication rate of 1.2% (n = 29 complications; 95% CI: 0.8-1.7%). Individual procedures had complication rates that ranged from 0 to 2.7%. There were 13 Grade I complications in 13 patients, 12 Grade II complications in 10 patients, 4 Grade III complications in 4 patients, and 0 Grade IV or V complications. No associations between complication risk and any patient demographics (age, sex, BMI), co-morbidities (diabetes, smoker), or procedure characteristics (type, region) were identified. CONCLUSION: This retrospective review provides an evidence-based estimate supporting the low level of risk associated with ultrasound-guided surgical procedures for patients from a variety of geographical settings who are seeking care at private and academic-affiliated clinics.

Two-Compartment or 4-Compartment Fasciotomy for Lower Leg Chronic Exertional Compartment Syndrome: A Systematic Review.

Patients with lower leg chronic exertional compartment syndrome are impaired due to exercise-related pain. Fasciotomy is the surgical gold standard. However, it is unknown whether number of simultaneously opened compartments affects outcome. The purpose of this systematic review was to compare patient-reported outcomes of a 2-compartment fasciotomy with a 4-compartment fasciotomy. Controlled clinical trials (randomized/nonrandomized), cohort studies and case series reporting on outcome following either 2-compartment or 4-compartment fasciotomy for lower leg chronic exertional compartment syndrome were searched until May 31, 2021 in PubMed, EMBASE, and Cochrane. Results were qualitatively synthesized. Risk of bias and levels of evidence were determined. Seven studies reporting on altogether 194 athletes and military personnel (mean age 24 y) were included. Quality assessment revealed a high risk of bias in all studies. Both 2-compartment and 4-compartment fasciotomy were associated with a 50% to 100% "return to activity" rate (in studies reporting group results separately: 2-compartment 90%-100%; 4-compartment 50%-100%) and a 41% to 100% "return to previous activity" rate (in studies reporting group results separately: 2-compartment 82-100%; 4-compartment 50%-100%) without significant differences. Mean Marx activity score of 1 study found a small significant standardized mean difference (0.196 [0.524,0.916]) favoring 4-compartment fasciotomy. Rate of satisfaction (2-compartment 74%-89%; 4-compartment 75%-100%) and residual symptoms (2-compartment 0%-36%; 4-compartment 0%-50%) indicated no group differences. In conclusion, a 2-compartment fasciotomy or a 4-compartment fasciotomy for lower leg chronic exertional compartment syndrome appears to be equally successful. However, included studies were hampered by methodological shortcomings (low sample size, selection bias, heterogeneity and no uniform outcome measures).

Systematic Review of Patient-Reported Outcome Measures for Patients with Exercise-Induced Leg Pain.

Background and Objectives: To determine the most commonly used patient-reported outcome measures (PROMs) in exercise-induced leg pain (EILP) and to identify specific PROMs for EILP in order to evaluate their psychometric properties and methodological quality. Materials and Methods: A strategic search was performed in different databases to identify and extract the characteristics of studies based on the use of PROMs in patients with EILP. Specific PROMs were evaluated according to the Terwee et al. and COSMIN criteria. Results: Fifty-six studies were included in the review. The Medial Tibial Stress Syndrome Score (MTSSS), Lower Extremity Functional Scale (LEFS) and Exercise-Induced Leg Pain Questionnaire (EILP-Q) were identified as specific PROMs for EILP. The Visual Analog Scale (VAS) was the most widely used instrument in the assessment of EILP. The methodological quality assessment showed six positive values for the LEFS, four for the MTSSS and three for the EILP-Q for the eight psychometric properties analyzed according to the COSMIN criteria. The evaluation of the nine psychometric properties according to Terwee showed five positive values for the LEFS and MTSSS, and three for the EILP-Q. Conclusions: The overall methodological quality of the PROMs used was low. The VAS was the most widely used instrument in the assessment of EILP, and the LEFS was the highest quality PROM available for EILP, followed by the MTSSS and EILP-Q, respectively.

Single incision, minimally invasive fasciotomy of the anterior and lateral leg compartments with decompression of the superficial peroneal nerve.

BACKGROUND: There is a considerable overlap of symptoms between chronic exertional compartment syndrome (CECS) of the anterior and lateral compartments of the lower leg and entrapment neuropathy of the superficial peroneal nerve (SPN). We describe a minimally invasive, single incision surgical technique for release of both the compartments and the SPN in the same setting. The operative technique involves a minimal anterolateral approach at the level where the SPN pierces the subcutaneous fascia. METHODS: Nineteen patients were operated with the method and 24 anterolateral compartments (5 cases with bilateral CECS) were released. Anterior and lateral, proximal and distal fasciotomies were performed sequentially with the use of a specific instrument designed for carpal tunnel release (KnifeLight®, Stryker). This is a modification of a fasciotome with an intergrated light source which allows for transillumination of the subcutaneous tissues. The SPN and its main branches with their anatomical variations were explored and decompressed at the same setting. RESULTS: Patients who met the inclusion criteria were reviewed at one year postoperatively with a Numeric Analog Pain Scale (NAS) and the Linkert satisfaction scale. There were 5 men and 10 women, aged 35.7 (21-60) years. The NAS scores improved by a mean 6 points (p<0.0001) postoperatively and 86.6% (13/15) of the patients were either satisfied or very satisfied with the operation. There were no intraoperative complications. There were two patients with SPN neuropathy symptoms postoperatively, one of whom required revision surgery. One patient had recurrence of less intense symptoms in the first postoperative year with no need for reoperation. CONCLUSIONS: The simultaneous release of the anterolateral compartment of the leg and decompression of the SPN with the described technique was safe and effective. It combined the advantages of a single, minimally invasive approach with the subcutaneous transillumination, and had a high patient satisfaction and a low recurrence rate. LEVEL OF EVIDENCE: Retrospective case series, Level IV.

Outcome following mini-open lower limb fasciotomy for chronic exertional compartment syndrome.

PURPOSE: The aim of this study was to report outcomes following mini-open lower limb fasciotomy (MLLF) in active adults with chronic exertional compartment syndrome (CECS). METHODS: From 2013-2018, 38 consecutive patients (mean age 31 years [16-60], 71% [n = 27/38] male) underwent MLLF. There were 21 unilateral procedures, 10 simultaneous bilateral and 7 staged bilateral. There were 22 anterior fasciotomies, five posterior and 11 four-compartment. Early complications were determined from medical records of 37/38 patients (97%) at a mean of four months (1-19). Patient-reported outcomes (including EuroQol scores [EQ-5D/EQ-VAS], return to sport and satisfaction) were obtained via postal survey from 27/38 respondents (71%) at a mean of 3.7 years (0.3-6.4). RESULTS: Complications occurred in 16% (n = 6/37): superficial infection (11%, n = 4/37), deep infection (3%, n = 1/37) and wound dehiscence (3%, n = 1/37). Eight per cent (n = 3/37) required revision fasciotomy for recurrent leg pain. At longer-term follow-up, 30% (n = 8/27) were asymptomatic and another 56% (n = 15/27) reported improved symptoms. The mean pain score improved from 6.1 to 2.5 during normal activity and 9.1 to 4.7 during sport (both p < 0.001). The mean EQ-5D was 0.781 (0.130-1) and EQ-VAS 77 (33-95). Of 25 patients playing sport preoperatively, 64% (n = 16/25) returned, 75% (n = 12/16) reporting improved exercise tolerance. Seventy-four per cent (n = 20/27) were satisfied and 81% (n = 22/27) would recommend the procedure. CONCLUSION: MLLF is safe and effective for active adults with CECS. The revision rate is low, and although recurrent symptoms are common most achieve symptomatic improvement, with reduced activity-related leg pain and good health-related quality of life. The majority return to sport and are satisfied with their outcome.

Chronic exertional compartment syndrome in the differential diagnosis of peripheral artery disease in older patients with exercise-induced lower limb pain.

OBJECTIVE: Peripheral artery disease (PAD) and chronic exertional compartment syndrome (CECS) both cause exercise-induced lower limb pain. CECS is mostly described in young individuals and may therefore not be considered in older patients with intermittent claudication. The aim of our study was to identify differences in characteristics and symptomatology between patients with CECS and PAD that may help in recognizing CECS in patients ≥50 years with exercise-induced lower limb pain. METHODS: In this case-control study, patients with CECS ≥50 years were selected from a prospectively followed cohort and compared with a sample of newly diagnosed patients with PAD ≥50 years. A questionnaire assessed frequency and severity of lower limb pain, tightness, cramps, muscle weakness, and altered skin sensation at rest and during exercise. RESULTS: At rest, patients with CECS (n = 43, 42% female, 57 years; range, 50-76 years) reported significantly more pain, tightness, muscle weakness and altered skin sensation (all P < .01) than patients with PAD (n = 41, 39% female, 72 years; range, 51-93 years). Having CECS was associated with a significantly higher combined symptom score at rest (P = .02). During exercise, patients with CECS experienced more tightness, muscle weakness and altered sensation (P < .01), but not pain and cramps (P = .36; P = .70). Exercise-induced complaints occurred much later in patients with CECS than in patients with PAD (15 minutes vs 4 minutes; P < .01). Persistence of pain over 4.5 minutes proved most discriminative for the presence of CECS (sensitivity, 95%; specificity, 54%; positive predictive value, 65%). Exercise cessation completely alleviated complaints in all patients with PAD (n = 41) but not in 73% (n = 29) of the patients with CECS. Ongoing discomfort strongly predicted the presence of CECS (sensitivity, 73%; specificity, 100%; positive predictive value, 100%). CONCLUSIONS: Patients with CECS ≥50 years report a symptom pattern that is different from patients with PAD. These differences may aid vascular surgeons in identifying older patients with CECS.

Significantly lower intramuscular pressure in the posterior and lateral compartments compared with the anterior compartment suggests alterations of the diagnostic criteria for chronic exertional compartment syndrome in the lower leg.

PURPOSE: To investigate distributions and identify possible differences in intramuscular pressure (IMP) values at 1 min post-exercise between the four muscle compartments of the lower leg, in patients with exertional leg pain with or without chronic exertional compartment syndrome (CECS). METHODS: A consecutive series of patients seeking orthopaedic consultation for exertional leg pain underwent IMP measurements between 2009 and 2018. The diagnosis of CECS was confirmed (n = 442) or ruled out (n = 422), based on the patient's history, clinical examination, and IMP measurements. RESULTS: The median (range) 1 min post-exercise IMP values in affected compartments in the patients diagnosed with CECS were 33 (25-53) mmHg (deep posterior), 35 (27-54) mmHg (superficial posterior), 40 (26-106) mmHg (lateral), and 47 (24-120) mmHg (anterior). In patients with no CECS, the median (range) 1 min post-exercise IMP values in the compartments were 12 (2-28) mmHg (deep posterior), 12 (2-27) mmHg (superficial posterior), 14 (2-26) mmHg (lateral), and 18 (4-34) mmHg (anterior). The IMP was significantly lower in the lateral and both posterior compartments than in the anterior compartment in both patients diagnosed with CECS and patients without CECS. CONCLUSION: The study demonstrates significantly lower IMP values in the posterior and lateral compartments compared to the anterior compartments. These findings suggest a lowering of the IMP 1 min post-exercise cut-off value for diagnosing CECS in the lateral and both posterior compartments, which may lead to improved treatment of patients with suspected CECS in the lower leg. LEVEL OF EVIDENCE: Level II.

A systematic review of fasciotomy in chronic exertional compartment syndrome.

BACKGROUND: Chronic exertional compartment syndrome (CECS) is an overuse injury typically seen in young and athletic patients. The five cardinal symptoms are pain, tightness, cramping, weakness, and paresthesia. These classically occur during exertion and disappear with cessation of the activity, with no permanent damage to tissues within the compartment; nonetheless, CECS presents a significant functional impairment to those affected. Regulating exercise has been shown to alleviate symptoms, but this may not be acceptable to some patients (eg, professional athletes). For patients who fail to respond to conservative management or where exercise reduction is unrealistic, fasciotomy can be considered. There are no established guidelines on the management of CECS, and it remains underdiagnosed. The aim of this systematic review was to compare the outcomes of patients suffering from CECS managed with either fasciotomy or nonoperative means by examining functional outcomes and resolution of symptoms. METHODS: MEDLINE and Embase databases and clinical trial registries were searched comprehensively; 219 articles were identified, and 14 articles were included in the systematic review. Given the heterogeneity between the studies in terms of outcomes reported, a qualitative synthesis was performed. RESULTS: The majority of included studies were retrospective cohort studies, with a single prospective cohort study. Studies included fasciotomies performed in the upper and lower limbs. The population of patients included military servicemen, motocross racers, and unselected patients. There is insufficient evidence in the literature to support conservative or surgical management over the other in the management of CECS. However, fasciotomy appears to be a safe approach, with satisfaction rates of 48% to 94%. Complications related to the fasciotomy included hematomas (2.7%-22.5%), nerve injuries (2.0%-18.6%), deep venous thrombosis (2.7%), and symptom recurrence (0.65%-8.4%). Up to 10.4% of patients required revision fasciotomy. CONCLUSIONS: There is no consensus on the optimal management of CECS and, as yet, no established international guidelines on treatment. This systematic review suggests that fasciotomy could be a safe and viable option in the management of patients suffering from CECS, with promising long-term results. Future research in the form of randomized controlled trials comparing conservative and surgical management would be beneficial.

Systematic review of outcome parameters following treatment of chronic exertional compartment syndrome in the lower leg.

OBJECTIVE: Surgery is the gold standard in the management of chronic exertional compartment syndrome (CECS) of the lower extremity, although recent studies also reported success following gait retraining. Outcome parameters are diverse, and reporting is not standardized. The aim of this systematic review was to analyze the current evidence regarding treatment outcome of CECS in the lower leg. MATERIAL AND METHODS: A literature search and systematic analysis were performed according to the PRISMA criteria. Studies reporting on outcome following treatment of lower leg CECS were included. RESULTS: A total of 68 reports fulfilled study criteria (n =; 3783; age range 12-70 year; 7:4 male-to-female ratio). Conservative interventions such as gait retraining (n =; 2) and botulinum injection (n =; 1) decreased ICP ( x -  =; 68 mm Hg to x -  =; 32 mm Hg) and resulted in a 47% (±42%) rate of satisfaction and a 50% (±45%) rate of return to physical activity. Fasciotomy significantly decreased ICP ( x -  =; 76 mm Hg to x -  =; 24 mm Hg) and was associated with an 85% (±13%) rate of satisfaction and an 80% (±17%) rate of return to activity. Return to activity was significantly more often achieved (P < .01) in surgically treated patients, except in one study favoring gait retraining in army personnel. CONCLUSION: Surgical treatment of CECS in the lower leg results in higher rates of satisfaction and return to activity, compared to conservative treatment. However, the number of studies is limited and the level of evidence is low. Randomized controlled trials with multiple treatment arms and standardized outcome parameters are needed.

M. Peroneus Quartus Causing Chronic Peroneal Compartment Syndrome in a Runner Treated by Endoscopic Fasciotomy: A Case Report.

We present the rare case of a 47-year-old male long-distance runner who was referred to our hospital with a longstanding pain in his left calf. Clinical history, as well as ultrasound and magnetic resonance imaging scans, showed an accessory peroneal muscle. This muscle was identified as a peroneus quartus muscle. On ultrasound, controlled intracompartmental pressure measurement, a chronic peroneal compartment syndrome, was diagnosed. We performed an endoscopic-assisted fasciotomy of the peroneal compartment. This resolved the patient's symptoms completely and allowed the runner to return to competition shortly after the surgery.

Presentation, diagnosis, and management of popliteal artery entrapment syndrome: 11 years of experience with 61 legs.

Popliteal artery entrapment syndrome (PAES) is still underdiagnosed yet it may significantly interfere with lifestyle, especially among young sportspeople, with symptoms like intermittent claudication. Although case reports and small case series are sometimes published, studies with larger populations are quite rare. This study summarizes our experience with PAES on 61 limbs (35 patients) over a period of 11 years, describing the demographics, the disease, and the diagnostic and therapeutic methods used with PAES patients. In a population of 327 consecutive explored symptomatic sportspersons, PAES was confirmed in 35 patients on 61 pathologic limbs. The median time with the symptoms before diagnosis was 34 months (range, 3-180 months). The mean age of patients was 30.5 years (range, 17-52 years) with 83% of males. The proportion of patients diagnosed with bilateral PAES was 74%. The main sports practiced were running (15 patients, 43%), soccer (nine patients, 26%), rugby (two patients), and athletics (two patients). Among 21 patients, intra-compartmental pressure measurements (ICP) found 18 (86%) to have an associated chronic exertional compartment syndrome (CECS). Among the patients followed up after PAES surgery, 80% were able to resume sport at a level comparable to that before the onset of pain. PAES could be sought earlier in young sportspeople who experience unexplained leg pain during exercise to diagnose the disease and avoid complications in a timely manner. Compartmental pressures should systematically be measured in the search for an associated CECS.

Effects of anterior compartment fasciotomy on intramuscular compartment pressure in patients with chronic exertional compartment syndrome.

BACKGROUND: Patients with chronic exertional compartment syndrome (CECS) have pain during exercise that usually subsides at rest. Diagnosis is usually confirmed by measurement of intramuscular compartment pressure (IMCP) following exclusion of other possible causes. Management usually requires fasciotomy but reported outcomes vary widely. There is little evidence of the effectiveness of fasciotomy on IMCP. Testing is rarely repeated postoperatively and reported follow-up is poor. Improved diagnostic criteria based on preselection and IMCP levels during dynamic exercise testing have recently been reported. OBJECTIVES: (1) To compare IMCP in three groups, one with classical symptoms and no treatment and the other with symptoms of CECS who have been treated with fasciotomy and an asymptomatic control group. (2) Establish if differences in IMCP in these groups as a result of fasciotomy relate to functional and symptomatic improvement. METHODS: Twenty subjects with symptoms of CECS of the anterior compartment, 20 asymptomatic controls and 20 patients who had undergone fasciotomy for CECS were compared. All other possible diagnoses were excluded using rigorous inclusion criteria and MRI. Dynamic IMCP was measured using an electronic catheter wire before, during and after participants exercised on a treadmill during a standardised 15 min exercise challenge. Statistical analysis included t-tests and analysis of variance. RESULTS: Fasciotomy results in reduced IMCP at all time points during a standardised exercise protocol compared with preoperative cases. In subjects responding to fasciotomy, there is a significant reduction in IMCP below that of preoperative groups (P<0.001). Postoperative responders to fasciotomy have no significant differences in IMCP from asymptomatic controls (P=0.182). CONCLUSION: Fasciotomy reduces IMCP in all patients. Larger studies are required to confirm that the reduction in IMCP accounts for differences in functional outcomes and pain reductions seen in postoperative patients with CECS.

Running mechanics of females with bilateral compartment syndrome.

[Purpose] Primary purpose was to compare running mechanics between healthy runners and runners with chronic exertional compartment syndrome (CECS) including overstride angles, ankle dorsiflexion (DF) angles, and foot strike patterns. The secondary purpose was to analyze the association between the overstride angles and ankle DF angles. [Participants and Methods] Running images of 7 female runners with bilateral CECS patients were captured at a time of the medical examination. Their running images were compared with gender, age, and body mass index matched 31 healthy control runners. [Results] The bilateral CECS female runners have a propensity of running with significantly greater overstride and ankle DF angles than the healthy female runners. There were no foot strike differences between the two cohorts. There were a non-significant, poor relationship between overstride and ankle DF angles in the healthy female runners while a significant, strong association was found between overstride and ankle DF angles in the bilateral CECS female runners. [Conclusion] Compared to healthy female runners, bilateral CECS female runners demonstrated different running mechanics including greater overstride and ankle DF angles. The two variables were strongly associated with each other in bilateral CECS female runners, but not in healthy female runners. This may potentially contribute to the mechanism of CECS development.

Chronic Exertional Compartment Syndrome in Athletes.

Chronic exertional compartment syndrome (CECS) refers to exercise-induced, reversible increases in pressure within well-defined inelastic fascial compartments leading to compromised tissue perfusion followed by functional loss, ischemic pain, and neurologic symptoms. Symptoms typically resolve when the activity ceases and there are usually no permanent sequelae. In the upper extremity, this condition most commonly affects athletes during sports requiring repetitive and vigorous gripping, such as rowers. In addition to clinical history and examination, a number of methods aid diagnosis, including compartment pressure measurements, magnetic resonance imaging, and near infrared spectroscopy. When symptoms persist despite conservative treatment, multiple operative techniques have been described to treat CECS including open, mini-open, and endoscopic release of involved compartments. We review the pathophysiology, diagnostic modalities, treatment strategies, and outcomes data for CECS of the upper extremity while highlighting areas of residual controversy.

Single minimal incision fasciotomy for the treatment of chronic exertional compartment syndrome: outcomes and complications.

INTRODUCTION: Chronic exertional compartment syndrome (CECS) is a common injury in young athletes, causing pain in the involved leg compartment during strenuous exercise. The gold standard treatment is fasciotomy, but most of the reports on its effectiveness include relatively small cohorts and relatively short follow-up periods. This study reports the long-term results of a large cohort of young athletes who underwent single-incision fasciotomy for CECS. MATERIALS AND METHODS: This a retrospective case-series study. All patients treated by fasciotomies performed for CECS between 2007 and 2011, in a tertiary medical institution. CECS was diagnosed following history taking and clinical evaluation, and confirmed by compartment pressure measurements. Ninety-five legs that underwent single-incision subcutaneous fasciotomy were included. Data on the numerical analog scale (NAS), Tegner activity score, and quality-of-life (QOL) as measured via the short form-12 (SF-12) were retrieved from all patients preoperatively and at the end of follow-up. RESULTS: The average time to diagnosis was 22 months and the mean follow-up was 50.1 months. Sixty-three legs underwent anterior compartment fasciotomy (an additional 30 legs also underwent lateral compartment release), and two legs underwent lateral and peroneal compartment releases. The average change in Tegner score was an improvement of 14.6 points. Similarly, the patients reported a significant improvement in the SF-12 and NAS scores. Satisfaction rates were high (average 75.5 %). The main complications were wound infection (2 patients) and nerve injuries (4 patients). Eight patients had recurrence. CONCLUSION: Single-incision fasciotomy leads to long-term improvement in the activity level and QOL of patients with CECS.

Differential examination, diagnosis and management for tingling in toes: fellow's case problem.

BACKGROUND: The diagnosis of chronic exertional compartment syndrome can be challenging as other pathologies involving bone, muscle, nerve and vascular structures can mimic the syndrome. The purpose of this Fellow's Case Problem is to describe the clinical decision-making and physical therapy differential diagnosis regarding a 25-year-old patient with un-resolved neurovascular complaints following chronic exertional compartment syndrome surgical release. DIAGNOSIS: After surgery, the patient's previous complaint of numbness and tingling in the plantar surfaces of her first and second toes of right foot was still present. The patient's concordant symptoms in toes were reproduced proximally in the lumbar spine and distally in the tarsal tunnel. DISCUSSION: The lumbar spine can refer symptoms to the lower extremities and needs to be ruled out as the source of the patient's complaint whenever neurovascular symptoms such as numbness and tingling are present. The discovery of the relationship of the lumbar spine with the tingling in the toes addressed one of the patient's primary concerns that was not resolved from the surgery. LEVEL OF EVIDENCE: 4.

Prevention and treatment of exercise related leg pain in young soldiers; a review of the literature and current practice in the Dutch Armed Forces.

Overuse injuries of the leg are a common problem for young soldiers. This article reviews the literature concerning the prevention and treatment of exercise related leg pain in military settings and presents the latest developments in proposed mechanisms and treatments. Current practice and treatment protocols from the Dutch Armed Forces are reviewed, with an emphasis on the most prevalent conditions of medial tibial stress syndrome and chronic exertional compartment syndrome. The conclusion is that exercise related leg pain in the military is an occupational problem that deserves further study.

Ultrasound-Guided Fasciotomy for Anterior Chronic Exertional Compartment Syndrome of the Leg.

Chronic exertional compartment syndrome is characterized by exertional pain and elevated intracompartmental pressures affecting the leg in physically active young people. In patients who have failed conservative measures, fasciotomy is the treatment of choice. This study presents a new method for performing fasciotomy using high-resolution ultrasound (US) guidance and reports on the clinical outcomes in a group of these patients. Over a 3-year period, 7 consecutive patients with a total of 9 involved legs presented clinically with anterior compartment chronic exertional compartment syndrome, which was confirmed by intracompartmental pressure measurements before and after exercise. After a US examination, fasciotomy under US guidance was performed. Preoperative and postoperative pain and activity levels were assessed as well as number of days needed to "return to play." All patients had a decrease in pain, and all except 1 returned to presymptomatic exercise levels with a median return to play of 35 days.
