Single-Incision Fasciotomy Decreases Infection Risk Compared with Dual-Incision Fasciotomy in Treatment of Tibial Plateau Fractures With Acute Compartment Syndrome.

OBJECTIVES

Comparison of surgical site infection (SSI) rates in tibial plateau fractures with acute compartment syndrome treated with single-incision (SI) versus dual-incision (DI) fasciotomies.

DESIGN

Retrospective cohort study.

SETTING

Two, Level-1, academic, trauma centers.

PATIENTS

Between January 2001 and December 2021, one-hundred ninety patients with a diagnosis of tibial plateau fracture and acute compartment syndrome met inclusion criteria (SI: n = 127, DI: n = 63) with a minimum of 3-month follow-up after definitive fixation.

INTERVENTION

Emergent 4-compartment fasciotomy, using either SI or DI technique, and eventual plate and screw fixation of the tibial plateau.

OUTCOMES

The primary outcome was SSI requiring surgical debridement. Secondary outcomes included nonunion, days to closure, method of skin closure, and time to SSI.

RESULTS

Both groups were similar in demographic variables and fracture characteristics (all P > 0.05). The overall infection rate was 25.8% (49 of 190), but the SI fasciotomy patients had significantly fewer SSIs compared with the DI fasciotomy patients [SI 18.1% vs. DI 41.3%; P < 0.001; OR 2.28, (confidence interval, 1.42-3.66)]. Patients with a dual (medial and lateral) surgical approach and DI fasciotomies developed an SSI in 60% (15 of 25) of cases compared with 21.3% (13 of 61) of cases in the SI group ( P < 0.001). The nonunion rate was similar between the 2 groups (SI 8.3% vs. DI 10.3%; P = 0.78). The SI fasciotomy group required fewer debridement's ( P = 0.04) until closure, but there was no difference in days until closure (SI 5.5 vs. DI 6.6; P = 0.09). There were zero cases of incomplete compartment release requiring return to the operating room.

CONCLUSIONS

Patients with DI fasciotomies were more than twice as likely to develop an SSI compared with SI patients despite similar fracture and demographic characteristics between the groups. Orthopaedic surgeons should consider prioritizing SI fasciotomies in this setting.
