IntroductionThe standard treatment for an acute compartment syndrome (ACS) of the lower leg is a four compartment fasciotomy. It can be performed through either one lateral or a lateral and medial incision. Selective fasciotomy, only opening the compartments with elevated pressure, is a less invasive procedure. The aim of this study was to describe a procedure of selective fasciotomy after pressure measurement and to determine its feasibility in a retrospective cohort study.MethodsAll patients with an ACS of the lower leg due to a proximal or tibia shaft fracture (AO 41 or 42) who received either a four compartment fasciotomy or a selective fasciotomy after pressure measurement between 2006 and 2016 were included. Every compartment with an intracompartment pressure of more than 30 mmHg was opened. The primary outcome was any missed compartment syndrome after selective fasciotomy. Secondary outcomes were reoperations for completing four compartment fasciotomy and persistent sensomotoric deficits.ResultsFifty-one patients with a mean age of 43 years (6-76) were included. Of these, 41 (80%) had a selective fasciotomy. There was no missed compartment syndrome. One patient had a reoperation 8 h after primary selective fasciotomy due to ACS of the superficial and deep flexor compartment. The anterior compartment had to be released in all patients. In 67%, the release of 2 compartments was sufficient. Six patients had postoperative sensomotoric deficits at discharge with full recovery during follow-up.ConclusionSelective fasciotomy is feasible and seems to be safe. Future comparative studies will have to focus on possible benefits of this less invasive treatment.
