Differences between primary and secondary definitive osteosynthesis for fractures of the lower leg with concomitant acute compartment syndrome

Abstract

Purpose

To analyze the differences in outcomes between primary and secondary definitive osteosynthesis for fractures of the lower leg with concomitant acute compartment syndrome (ACS).

Methods

From our trauma database, we identified a total of 107 patients with 126 fractures of AO/OTA type 41–44 and 120 ACS from January 01, 2001 to December 31, 2015 who were treated with primary or secondary definitive osteosynthesis after concomitant fasciotomy.

Results

Seventy-one patients with 77 fractures of AO/OTA classification type 41–44 suffering ACS received primary definitive osteosynthesis at the time of compartmental incision (POCI) and were compared to 36 patients with 49 fractures of AO/OTA type 41–44 and ACS, who received secondary definitive osteosynthesis after compartmental incision and soft tissue coverage (SOCI). Patients with POCI had a significantly shorter length of hospital stay with significantly fewer necessary surgeries to achieve definitive fracture treatment and soft tissue closure than SOCI patients (p ≤ 0.001). The overall rate of infections in both groups was 13%, without any difference between POCI and SOCI.

Conclusions

POCI for AO/OTA fractures type 41–44 with ACS is a safe and effective procedure without increasing the infection rate compared to a gradual treatment (SOCI). However, the possible selection bias due to the retrospective study design needs to be considered.
