Clinical analysis of three internal fixation devices for intertrochanteric fractures of femur / 中华创伤骨科杂志

Objective To compare the clinical effects of 3i nternal fixation devices,130?comp res-sion-plate,Richards screw-plate system and Gamma locking nail,in tre atment of intertrochanteric fractu res of femur in order to provide evidence fo r clinical choice.Methods The 3different internal fixation devices were statistically compared in terms of t heir surgery time,volume of operative bleeding,hospitalization time,postop-erative complications,as well as excellent and good rate of function in t reatment of intertrochanteric frac tures of femur.Results Compared with the other two treatmen t groups,the Gamma locking nail grou p presented the best therapeutic effects.Its posto perative complications were significantly lower and its excellent and f ine rate of function was significantly higher t han those of the other two groups.Conclusion Gamma locking nails are a kind of effective internal fixation device for the treatment of intertro chanteric fractures in elderly patients,because it has better biomechanical properties which facilitate fracture healing and recovery of hip joint function.[

Clinical application of three internal fixation devices to treat fractures of femural shaft / 中华创伤骨科杂志

Objective To study the value of three internal fixation devices (interlocking intramedullary nail, cloverleaf type intramedullary nail ,compression plate) in treatment of fractures of femural shaft. Methods All the patients were divided into three groups randomly. 32 patients were treated with the interlocking intramedullary nail , 67 patients with the cloverleaf type intramedullary nail, and 47 patients with the compression plate. Results After the three internal fixation devices were used in the fractures of femural shaft. All the patients were followed up for 6 months to 144 months. The total rates of postoperative deformity healing and delayed healing and nonunion were 3.1%, 6.0%and 10.6%respectively. The rates of the internal fixation failure were 0%, 4.5%and 17.0%respectively. The rates of excellent function recovery of lower limbs were 81.3%, 70.1%and 59.6%. Conclusions The data show that the curative effects of the interlocking intramedullary nail is better than those of the cloverleat type intramedullary nail and the plate in treatment to fracture of femural shaft.
