Endoscopic fasciotomy for chronic exertional compartment syndrome of the forearm:Systematic review of outcomes and complications

BACKGROUND Endoscopic fasciotomy of the forearm for chronic exertional compartment syndrome(CECS)has gained popularity recently.AIM To systematically review the literature of endoscopic fasciotomy for CECS of the forearm,aiming to assess the outcomes and complications of the different endoscopic fasciotomy techniques described in the literature.METHODS On January 18,2021,PubMed and EMBASE were searched by 3 reviewers independently,and all relevant studies published up to that date were considered based on predetermined inclusion/exclusion criteria.The subject headings“endoscopic fasciotomy”and“compartment syndrome”and their related key terms were used.The Preferred Reporting Item for Systematic Reviews and Meta-Analyses statement was used to screen the articles.RESULTS A total of seven studies including 183 patients(355 forearms)were included.The mean age of the patients was 31.2 years(range:15-42 years).The postoperative follow-up duration ranged from 6 wk to 4.9 years.All patients were able to return to sport activities between postoperative weeks 1 to 8.Recurrence of the compartment syndrome occurred in three patients,giving a rate of 1.6%per patient and 0.8%per forearm.The overall complication rate was 8.7%per patient,and 4.5%per forearm.The most common reported complication was hematoma(7 forearms;2.0%).CONCLUSION Endoscopic fasciotomy for CECS of the forearm has favorable short-and midterm outcomes with very low recurrence and complication rates.This,however,needs to be confirmed in larger,long-term follow-up,prospective,comparative studies between open,mini-open and endoscopic fasciotomy techniques.
