ABSTRACT
Objective To study the influence of early dynamization of interlocking intramedullary nail on the treatment effect of the patients with lower limb fracture .Methods 62 patients with lower limb fracture treated with interlocking intramedullary nail in our hospital from June 2010 to March 2012 were selected as the research subjects and divided into the control group and the obser-vation group with 31 cases in each group according to random number table .The control group was treated with routine treatment method ,while the observation group was treated with early dynamization .Then the Johner-Wruch score ,healing time ,rate of ad-verse fracture healing ,incidence rate of complications and fracture healing related factors before and after the treatment were ana-lyzed and compared .Results The Johner-Wruch score excellent and good rate of the observation group was higher than that of the control group ,the healing time was shorter than that of the control group ,the rate of adverse fracture healing and the incidence rate of complications were lower than those of the control group ,the fracture healing related factors after treatment were all better than those of the control group ,the differences had statistical significance (all P<0 .05) .Conclusion The early dynamization of interloc-king intramedullary nail has the better effect for treating lower limb fracture and its influence on the fracture healing related factors is better too .
ABSTRACT
Objective: To evaluate the result of operative treatment of hip dislocation combined with fractures of the femoral head. (Pipkin fracture). Methods: 32 cases were classified according to Pipkin classification,including 8 cases of type Ⅰ,15 cases of type Ⅱ,3 cases of type Ⅲ and 6 cases of type Ⅳ. Various surgical procedures were taken according to the classifications,ages,preoperative images and intraoperative check of the patients. Open reduction and fixation were taken in 30 patients and total hip replacement were performed in 2 patients. Results: Follow-up averaged 28 months,the post-operative function in 27 cases of internal fixation were: excellent in 11 cases (40.7%),good in 11 cases(40.7%), fair in 3 cases(11.1%),poor in 2 case (7.5%). The excellent rate was 81.4%. Conclusion: The key to good result for treating Pipkin fracture is early diagnosis and early operation. Operative approach should be chosen with various situations. Internal fixation with absorbable screw is an ideal method.
