IntroductionWhile there is no consensus on the best surgical procedure for post-burn axillary contractures, it is crucial to consider the elongation rate along the scar axis as a useful measurement index for determining the optimal surgical approach. The square flap and five flap z-plasty techniques are commonly employed scar lengthening procedures to address scar contractures in the axilla. These approaches successfully disrupt the linear scar, leading to significant elongation while reducing transverse tension. Our study aims to compare the increase in band length and functional results of these two approaches for treating post-burn contractures in the axilla.MethodsA retrospective study was carried out utilizing data from 34 patients with mild-to-moderate band-like contractures located on the anterior or posterior axillary lines who underwent surgical correction through either the square flap method or five-flap z-plasty technique. The effectiveness of surgical methods was evaluated using two objective indices: improvement in contracture band length and improvement in abduction angle at the shoulder joint.ResultsAll patients achieved complete contracture release. There is no statistically significant difference between the two groups regarding the improvement in the degree of abduction postoperatively. Although there was a significant increase in the length of the contracture band postoperatively in both groups, the average increase in length for cases treated with a square flap was significantly greater than those managed with a five-flap Z-plasty (87.7 ± 44.8 % vs. 38.80 ± 11.119 %,) respectively.ConclusionThe square flap technique is considered a better alternative to the commonly used 5-flap Z-plasty method because it can achieve higher elongation in the contracture band, restore joint function, and create optimal shape when dealing with single linear band contractures over the axilla.Copyright © 2024 Elsevier Ltd and ISBI.
