O’Neill DC, Mortensen AJ, Tomasevich KM, et al. - This study was undertaken to explore the impact of venting on the distraction of the hip during arthroscopy on a post-free traction table for fixed traction forces ranging from 0 to 100 pounds. Researchers included 58 hips in 57 patients who had undergone surgery by the senior author between November 2018 and July 2019. The data indicated that compared with the pre-vented state, venting prior to applying traction on a post-free traction table increases the distraction distance achieved for a given traction force at multiple levels of traction. The outcomes imply venting the hip joint prior to the application of traction may serve to decrease the maximal amount of traction required to safely instrument the hip arthroscopically.
