Résumé
OBJECTIVE@#To analyze and compare the hidden blood loss of minimally invasive percutaneous plate osteosynthesis(MIPPO) combined with locking plate fixation and intramedullary nail fixation in the treatment of tibial shaft fracture.@*METHODS@#One hundred and ninety-one cases of tibial shaft fracture treated from January 2017 to January 2019 were analyzed retrospectively. The patients were all treated with closed reduction and divided into two groups:group A (110 cases) and group B (81 cases). In group A, 78 males and 32 females were treated with MIPPO combined with locking plate. The age ranged from 19 to 74 (45.32±11.79) years old. According to AO classification, 42cases were type 42-A, 45 were type 42-B and 23 were type 42-C fractures. Group B was treated with intramedullary nail, including 65 males and 16 females, aged 19 to 84 (45.44± 14.32) years old. According to AO classification, there were 39 cases of type 42-A, 29 cases of type 42-B and 13 cases of type 42-C. The operation time, intraoperative blood loss and hidden blood loss were observed and compared between the two groups.@*RESULTS@#On the first day, the hidden blood loss was (155.27±47.89) ml in group A and (160.43±131.42) ml in group B, the difference was statistically significant (0.05).@*CONCLUSION@#In the treatment of tibial shaft fracture with intramedullary nail, there is obvious hidden blood loss, which is much higher than expected.
