Mini-Open Posterior Compartment Release for Chronic Exertional Compartment Syndrome of the Leg

Return to Sport Rates and Subjective Outcomes Are Similar After Open or Endoscopically Assisted Compartment Release for Chronic Lower-Extremity Exertional Compartment Syndrome

Purpose

To retrospectively compare return to sport rates and subjective outcomes of patients who underwent open or endoscopic compartment release for the surgical management of chronic exertional compartment syndrome.

Methods

This was a retrospective review of patients who underwent lower-extremity fasciotomy for chronic exertional compartment syndrome from June 2012 to June 2020. Eligibility included patients 15 to 45 years of age who identified as an athlete and had at least 6 months of follow-up. Fasciotomies for trauma or infection were excluded. One surgeon exclusively performed each type of surgery. Postoperative outcome measures included the Lower Extremity Functional Scale, the Marx Activity Scale, and a return to play survey.

Results

In total, 24 patients (13 endoscopically assisted fasciotomies, 11 open fasciotomies) had a mean follow-up of 3.8 ± 2.1 years; 19 patients returned to their sporting activity. No significant difference existed between return to play rates (P = .630) or return to play times (P = .351). There were no significant differences between the groups in the Lower Extremity Functional Scale score, Marx Activity Scale score, Single Assessment Numeric Evaluation score, pain score at rest, and during sporting activity. Overall satisfaction rates were found to be significantly greater in the endoscopically assisted fasciotomy group (P = .041).

Conclusions

In this small sample of heterogenous groups of patients, we found no significant differences in return to sport rates or subjective results after surgery. Patients experienced a high subjective recurrence rate. The endoscopically assisted fasciotomy group reported greater subjective patient satisfaction compared with the open fasciotomy group.

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).

Chronic Exertional Compartment Syndrome: A Clinical Update

Chronic exertional compartment syndrome is a debilitating condition primarily associated in highly active individuals with an estimated incidence of approximately 1 in 2000 persons/year. The etiology remains unclear to date. The differential diagnosis includes, but is not limited to stress fractures, medial tibial stress syndrome, and popliteal artery entrapment syndrome. Clinical signs and symptoms include pain in the involved compartment with exertion dissipating quickly after activity. Diagnostic tests include intramuscular compartment pressure testing, magnetic resonance imaging, near-infrared spectrometry as well as shear wave electrography. Treatments consist of nonsurgical, surgical, or the combination of the two. Gait retraining and the use of botulinum toxin appear most promising. Diagnostic lidocaine injections are emerging as a prognostic and mapping tool. Minimal invasive surgical options are being utilized allowing quicker return to activity and decreased morbidity. This article reviews the anatomy, clinical signs and symptoms, diagnostics, nonsurgical, and surgical treatments for chronic exertional compartment syndrome.

Don't Just Blame it on the Veins: An Update on Vascular Exertional Limb Pain

Exertional limb pain is a common problem encountered in recreational and competitive athletes. Affecting both the upper and lower extremities, this broad entity can be musculoskeletal, vascular, neurologic, oncologic, or infectious in origin. This article focuses on the vascular causes of exercise-related extremity pain, which encompass a cadre of elusive diagnoses. Specifically, we examine arterial endofibrosis, popliteal artery entrapment syndrome, and chronic exertional compartment syndrome of both the upper and lower extremities. For each of these conditions, we offer updates regarding the respective epidemiology, common signs and symptoms, worthwhile diagnostic modalities, and pertinent treatment options, all based on evidence and reports published over the past year.
