| Objective:To explore the reconstruction of the femoral offset in THA operation,and to explore the incidence of double lower limbs length difference and unequal length.The purpose of the study can be divided into the following three aspects:first,on the lower extremities after reconstruction of femoral offset reconstruction patients and non patients with unequal rate difference analysis;secondly,further analysis of the corresponding correlation in patients with lower limb length after THA surgery with double lateral femoral offset between on the basis of the above research.Again,the reconstruction of the femoral offset in patients were retrospectively analyzed,so as to explore the relationship between the length of the double lower limb and different reconstruction of femoral offset.And further investigate whether the length of the double lower limb can promote the effect of the difference of the eccentric distance.Method:(1)basic data.The basic data of this study came from 115 patients(115hips)received in the Department of orthopedics of the Municipal Hospital of Qingdao University.There were 61 cases of male and female patients and 54 cases,respectively,the total hip replacement was 61 hips and 54 hips,of which there were 60 cases and 55 cases respectively.The patients involved in this study were aged between 35-80 years old,and the average age was 61.78 years.There were 67 cases of aseptic necrosis of the femoral head in 115 cases.All patients were followed up for 0.25 years to 1 years.The average follow-up period was 7.2 months.(2)x ray film.In 115 patients before and after surgery were performed pelvic radiograph film,X-ray vertical projection in the distance with 1m distance,and enlarge the unified proportion of 1.15:1,the security of all patients at least above the middle femur 2/3 site can appear in the X-ray film.(3)data measurement.The data in this study were directly measured in X-ray,the specific method is:first,to identify patients with femoral anatomic axis and bilateral femoral head center in X-ray position,and in order to measure the bilateral femoral eccentricity;secondly,from the X-ray finding of bilateral teardrop and to draw level the reference line,combined with the reference line to measure the distance between the rotor and the small vertex,and deduces the length difference of lower limbs.(4)using the prosthesis template,select the prosthesis with minimal impact on the bilateral femoral offset.In this study,all patients withprosthesis template were determined by the same group of physicians.(5)in this study,we used the Excel and SPSS20.0 software on the statistical analysis,statistical treatment were done t test,the use of standard deviation to the line data show.When the statistical P test value is greater than 0.05,the result is judged to have no statistical difference,and vice versa with a statistically significant difference.Results:the following results were obtained through the study.First,there was a positive correlation between the difference of the length of the lower limbs of the patients after THA surgery and the difference of the femoral offset(r=0.632,P<0.05).Second,92 cases were taken THA postoperative femoral offset reconstruction of patients with 71 cases of the limb length of treatment,and 23 patients without reconstruction in patients with only 5 patients achieved after the treatment of limb length to.There was significant difference in the above differences(x2=25.229.,P<0.05).Third,the difference between the minimum and the maximum difference of the bilateral femoral offset in the majority of patients with femoral offset reconstruction(x2=19.237.,P<0.05).Conclusion:in patients with THA surgery should maximize the use of favorable surgical conditions,for patients with femoral offset reconstruction,so as to promote the patients after surgical treatment of limb can be restored to the same length,reduce the incidence of Unequal Growth of the body,so as to improve the treatment effect of the patients and improve their quality of life. |
