The Clinical Study Of The Treatment Of Early Necrosis Of The Femoral Head With Ganz Dislocation

ObjectiveWith the improvement of modern Imaging technology and diagnosis technology, especially MRI extensive use, making more and more patients with avascular necrosis of the femoral head are diagnosed in early stage, Granz dislocation is a new method for curing early osteonecrosis,providing a new orientation for hip-preserving. This article mainly through compare clinical curative effect of Ganz dislocation and allograft fibula support technology in the treatment of femoral head necrosis, proving a certain amount of clinical experience and theoretical basis for the treatment of early osteonecrosis.Methods60 early osteonecrosis patients treatment cases were collected for observation and analysis, all of which are clinical cases in the Femoral Head Department of our hospital from February 2014 to February 2015. The 60 cases were randomly divided into Observation Group (Ganz dislocation technology) and Control Group (Impacting bone graft and fibular allograft). Using the hip joint function assessment table, VAS table, rating the hip joint function, the two groups of cases were scored in the first 1 weeks, the 2 weeks, 1nd months,3th months,6th months and 12th month respectively by a Clinical Efficacy Questionnaire on Early Osteonecrosis, to turn the last follow-up imaging score, postoperative abandon time, clinical curative effect and complications. By means of the two groups of cases score comparison before and after operation, observing the difference of the indicators. At the same time, cases in the two groups are compared and systematic analyzed to evaluate the treatment efficacy. Repeated measures analysis of variance, are used to observe the overall difference of two groups of patients.ResultsThere was no statistical significance in terms of gender, age, pain score, and Harris score, in the two groups of cases before treatment. Two groups of patients Harris score after repeated measures analysis of variance, joint function in patients with two groups of Harris score compared in different measuring time F=3202.696, P=0.00;Observation group compared with control group joint function score, F=4.954, P=0.030;In time compared with group interaction, F=3.839, P=0.005).2 weeks after surgery scores higher than in observation group and control group in January, in the subsequent follow-up, observation group score higher than the control group. At the end of the two groups of patients with radiographic grading by two independent samples T test, P=0.017). VAS score in both groups after repeated measurements analysis of variance and compared in different measuring time F=945.390, P= 0.00;Observation group compared with control group VAS score, F=29.718, P =0.000; In time compared with group interaction, F=9.833, P=0.000).1 week, 2 weeks after surgery in the control group score is lower than the observation group, in the subsequent follow-up, the score of observation group were lower than the control group. Two groups of patients with postoperative turn abandon time checked by Fisher, P=0.029).Two groups of patients with clinical efficacy have examined the Mann-Whitney and P=0.024. Two groups of patients with postoperative complications have examined the Mann-Whitney, P=0.193). The complication rate of observation group was higher than the control group, P>0.05, and there was no statistical significance.ConclusionSurgical trauma of the Ganz dislocation technology is opposite bigge r than the allograft fibula supporting, early postoperative joint functio n score below with fibula support, but the operation to removing the dead bone sufficiently, fully support and firm, joint function score are hig her than the fibula support technique in the subsequent follow-up, two ki nds of operation are all an effective way for the treatment of early avas cular necrosis, and the latter operation difficulty is relatively easy, s hort learning period, suitable for application in basic-level hospitals.
