Bläsius FM, Link BC, Beeres FJP, et al. - Researchers sought to characterize the dynamics of changes in microcirculation following open reduction and internal fixation (ORIF) vs a minimally invasive approach (MIA) in calcaneal fractures. Nineteen patients (44 years, range 21.9–71.0 years; 15 underwent ORIF and 9 underwent MIA) were enrolled. The ORIF group had higher postoperative blood flow (BF) and oxygen saturation at the 2mm and 8mm depths. Both groups displayed an increase in the BF at the 2mm and 8mm depths after surgery. The generally accepted phases of soft tissue wound healing were supported by the spectrophotometry results. Surgical techniques did not influence the postsurgical changes in microcirculation and Wound and fracture healing may primarily determine these changes.
