Surgical fracture fixation on a traction table is the gold standard for treatment, but the effect on tissue microcirculation is unknown. Microcirculation could be impaired by the pull on the soft-tissue or by a release of vasoactive factors. We hypothesized that intraoperative traction impairs soft-tissue microcirculation. Materials and Methods: In 22 patients (14 women, eight men), average age 78 years (range 36\u201396 \u00b1 14), with trochanteric femur fractures, non-invasive laser-Doppler spectrophotometry was used to assess oxygen saturation, hemoglobin content, and blood flow in the skin and subcutaneous tissue before and after application of traction. Measurements were recorded in nine locations around the greater trochanter at a depth of 2, 8, and 15 mm before and after fracture reduction by traction. Results: No differences were found in any depth with traction compared to without (oxygen saturation: p = 0.751, p = 0.308, and p = 0.955, haemoglobin content: p = 0.651, p = 0.928, and p = 0.926, blood flow: p = 0.829, p = 0.866, and p = 0.411). Conclusion: In this pilot study, the application of traction does not affect skin and subcutaneous microcirculation in the surgery of proximal femur fractures.<\/jats:p>","DOI":"10.3390\/medicina57090884","type":"journal-article","created":{"date-parts":[[2021,8,30]],"date-time":"2021-08-30T22:49:51Z","timestamp":1630363791000},"page":"884","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Trochanteric Femur Fractures: Application of Skeletal Traction during Surgery Does Not Alter Soft-Tissue Microcirculation"],"prefix":"10.3390","volume":"57","author":[{"given":"Kenneth P.","family":"van Knegsel","sequence":"first","affiliation":[{"name":"Department of Orthopaedic and Trauma Surgery, Cantonal Hospital of Lucerne, Spitalstra\u03b2e 16, 6000 Lucerne, Switzerland"},{"name":"AO Research Institute Davos, Clavadelerstrasse 8, 7270 Davos Platz, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9512-2910","authenticated-orcid":false,"given":"Bergita","family":"Ganse","sequence":"additional","affiliation":[{"name":"Werner Siemens Foundation Endowed Chair for Innovative Implant Development, Clinics and Institutes of Surgery, Saarland University, 66421 Homburg, Germany"},{"name":"Department of Trauma, Hand and Reconstructive Surgery, Saarland University Hospital, 66421 Homburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pascal C.","family":"Haefeli","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic and Trauma Surgery, Cantonal Hospital of Lucerne, Spitalstra\u03b2e 16, 6000 Lucerne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Filippo","family":"Migliorini","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University Hospital RWTH Aachen, Pauwelsstrasse 30, 52074 Aachen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mario F.","family":"Scaglioni","sequence":"additional","affiliation":[{"name":"Department of Plastic and Hand Surgery, Cantonal Hospital of Lucerne, Spitalstra\u03b2e 16, 6000 Lucerne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bryan J.
