Innovative ‘Push Screw’ as reduction aid for minimally invasive fixation of calcaneus fracture:

摘要

Category:TraumaIntroduction/Purpose:Percutaneous reduction of depressed and rotated articular fragments is the most challenging job during minimally invasive fixation of fracture calcaneus. A solid, fully threaded, flat ended, 6.5 mm cancellous ‘Push Screw’ designed by us, serves as novel innovative tool for this purpose. ‘Push Screw’, by its pushing ability; not only reduces the articular fragment but also carries with it a big chunk of underlying subchondral cancellous bone for fixation of subarticular raft screws. We present a study of 28 cases of calcaneus fractures treated with minimally invasive techniques where ‘Push Screws’ were utilized to gain articular reduction of subtalar as well as calcaneocuboid joint.Methods:Twenty eight intra-articular calcaneus fracture cases where ‘Push Screw’ assisted reduction was done were included in present study. Image assisted method of achieving reduction with ‘Push Screws’ comprised of placement of a subarticular guide wire, drilling and tapping of a pilot hole...
