Abstract: Objective To compare the curative effect of bridging combined internal fixation system and locking compression plate in the treatment of comminuted femoral shaft fractures.Method The comminuted femoral shaft fractures admitted to our hospital from January 2017 to June 2021 were retrospectively analyzed.A total of 97 patients were included,of which 42 underwent internal fixation with locking compression plates (plate group),and 55 underwent internal fixation with Bridge-link combined fixation (bridge group),followed up for at least 12 months,The perioperative data,follow-up data and complications of the two groups were collected and compared.Results Compared with the plate group,the bridging group had shorter operation time[（95.37±19.31）min vs.（77.83±15.32）min],less intraoperative bleeding[(425.37±47.56）ml vs.（398.72±43.29）ml],less postoperative drainage[(123.42±19.87）ml vs.（106.39±14.20）ml],and shorter hospital stay[(19.31±4.26）d vs.（16.24±3.79)d];the one-year follow-up found that the bridging group had better hip joint and knee joint mobility[hip：（125.35±17.11）°vs. （132.31±15.47）°;knee：（131.49±18.24）° vs. （139.68±16.69）°] and faster fracture healing[（6.28±1.07）m vs. （5.42±0.87）m],and the Harris score[（77.57±6.39） vs. (83.49±9.31）] and HSS score [（80.32±7.79） vs. （85.35±6.90）] were higher than those in the steel plate group（all P<0.05）.There were no significant differences in incision length and complications between the two groups (P>0.05).Conclusion Compared with locking plate,bridging combined internal fixation in the treatment of comminuted femoral shaft fractures has less surgical trauma,faster fracture healing and better postoperative function.
