Prospective randomized comparison of early versus newer-generation vertebral access devices for kyphoplasty

91 compression fractured vertebral bodies in 65 patients were randomized to receive a balloon kyphoplasty with vertebral access achieved with the use of a Joline Vertebrae Access Device or one of two newer generation access devices (Joline RapidIntro Vertebrae Introducer Device; Joline SpeedTrack Vertebra Introducer Device). The primary outcomes of interest include operative time, intra-operative irradiation time and radiation dose area product. Results revealed no significant differences in all outcomes between the 3 groups.
