Inci F, Yildirim AO, Kocak C, et al. - Researchers conducted this retrospective study to assess the effectiveness of vascular damaged nonunions with treated induced membrane (IM) technique. This investigation involved tibial defect nonunions of 24 patients with treated IM technique, from January 2014 to December 2018. The average time to union (40.18 ± 10.01 weeks – 38.61 ± 11.20 weeks) and the mean defect size (6.54 ± 1.75 cm – 6.61 ± 1.85 cm), no statistical differences were obtained between two groups. While nonunions with vascular damage may require more surgery and spacer duration vs without vascular damage, a comparable time was achieved with union and union rate.
