ABSTRACT
BACKGROUND:
The aim of this study was to determine the incidence of missed compartment syndrome in tibia fractures treated with and without regional anesthesia.METHODS:
A retrospective chart review was performed of patients with operative tibial shaft or plateau fractures at a single level-one trauma hospital between January 2015 and April 2022 with a minimum of 3-month follow-up. Patients under 18 years of age, an ipsilateral knee dislocation, known neurologic injury at presentation, or prophylactic fasciotomy were excluded. We defined missed acute compartment syndrome (ACS) as a postinjury motor deficit still present at the 3-month postoperative appointment. For patients that received a peripheral nerve block, we recorded whether a continuous perineural catheter or one-time single-shot injection was performed, and the number of nerves blocked. Incidence rates for ACS were calculated with exact binomial 95% confidence intervals (CIs). Morphine milligram equivalents (MMEs) consumed 24 hours after surgery, use of nerve block, nerve block timing, and type of block were compared using Mann-Whitney and Kruskal-Wallis nonparametric tests. Statistical significance was defined as P < .05.RESULTS:
The incidence of compartment syndrome diagnosed and treated during index hospitalization was 2.2% (17/791, 95% CI, 1.3%-3.4%). The incidence of missed ACS was 0.9% (7/791, 95% CI, 0.4%-1.8%). The incidence of missed ACS was not different between those who received nerve block 0.7% (4/610, 95% CI, 0.2%-1.7%), and those who did not (1.7% (3/176, 95% CI, 0.4%-4.8%) P = .19). Within patients receiving a nerve block, all patients with missed ACS (n = 4) received a perineural catheter. Similar missed ACS rates were observed between tibial shaft and plateau fractures. Patients receiving a nerve block had lower MME compared to those who did not receive a nerve block (P < .001).CONCLUSIONS:
The results do not provide evidence that perioperative regional anesthesia increases the incidence of missed ACS in patients with operative tibial shaft or plateau injuries. but does decrease postoperative opioid requirements.
