Reduced pre-operative skin oxygen saturation predicts revision after open reduction and internal fixation in calcaneal fractures: A reduced pre-operative oxygen saturation as measured by laser-Doppler spectrophotometry in 8 mm depth is associated with revision surgery after open reduction and internal fixation of calcaneal fractures through an extended lateral approach

| description | Purpose
To assess which pre-operative parameters correlate with wound revisions after an extended lateral approach to the calcaneus.
Methods
Pre-operative laser-Doppler spectrophotometry was applied in patients undergoing open reduction and internal fixation. The number of wound revisions was recorded during pos-toperative follow-up. Spearman rho analysis was used to identify factors associated with wound revision and receiver operator characteristics curves were calculated for the identified factors.
Results
Thirty-four patients (29 men, 5 women; 37 calcanei) with a mean patient age of 43 ± 14 years were analyzed. The minimal oxygen saturation value at the five measurement locations as well as the minimal value for flow correlated negatively with wound revisions (
p
value = 0.025 and 0.038, respectively).
The area under the curve for the pre-operative minimal value of oxygen saturation was 0.841 (95%CI 0.64–1.00,
p
= 0.028), indicating a good accuracy as a test to predict wound revision.
Conclusion
A pre-operative oxygen saturation of at least 20.5% across five measurement points along the anticipated incision identified all patients not needing a wound revision (negative predictive value 100%). On the other hand, patients with at least one measurement below 20.5% were at risk for wound revision surgery (sensitivity 100%, specificity 48.5%).
