Abstract：[Objective] Hollow double compression screw fixation were retrospectively analyzed the clinical effect of treatment of Hoffa fractures .[Methods] From 2004 to 2013 ,a total of 21 Hoffa fracture patients were recruited .There were 13 males and 8 females .And the causes were traffic accident ( n=15) ,high fall‐ing ( n=4) and crush injury ( n=2) .According to the Letenneur scheme ,the types were Ⅰ( n=11) ,Ⅱ( n=6) and Ⅲ ( n =4) .And the fractures were closed ( n=15) and open ( n=6) .Double hollow compression screw was applied for fracture fixation .And postoperative rehabilitation exercise was implemented in a timely manner .[Results] The average follow‐up period was 21 .5 (6~36) months .During follow‐ups ,osseous heal‐ing was achieved without perioperative vascular or nerve injury ,wound infection ,screw loosening or rupture . Postoperative function assessments were based on Letenneur system .And the outcomes were excellent ( n =18) ,fair ( n =2) and poor ( n =1) .And the excellent rate was 85 .7% .[Conclusion]Hollow double com‐pression screw is efficacious for Hoffa fractures .And it offers the advantages of mini‐invasiveness ,reliable fix‐ation and quick recovery of postoperative functions .
