Comparison of therapeutic effects among three intramedullary fixation system for treatment of tibial fracture in 79 cases / 中国组织工程研究

ABSTRACT

A total of 79 tibial fracture patients (47 males and 32 females; 16 to 73 years old) were selected from Department of Orthopedics, Huangbu Hospital of Huidong City, including 19 cases of open fractures and 60 of closed fractures. Forty-eight fractures in 79 patients were fixed with interlocking nails, 19 by revolving self-locking nail, and 12 by auto compressive locking nail. Operations were all successful. The average operation time was (102 ?10) minutes in the interlocking group, (65?10) minutes in the revolving self-locking nail group and (100?10) minutes in the auto compressive locking nail group. The patients were followed up for 6-10 months. In the interlocking group, one breakage of the screws was found, with one superficial infection and the other 3 achieved delayed bone fracture. The healing time of interlocking group was (21.0?3.2) weeks and the excellent rate of function recovery was (85.42?5.20)% by Johner-Wruh. In the revolving self-locking nail group, one developed delayed bone facture and the other one achieved dislocation; the healing time was (20.0?3.6) weeks and the excellent rate of function recovery was (84.21?4.10)%. In the auto compressive locking nail group, one had loosening screw and the other one achieved superficial infection. The healing time was (17.0?2.8) weeks and the excellent rate of function recovery was (91.67?3.70)%. The excellent and good rate in auto compressive locking nail group was significantly greater than the other groups (P
