Three Methods Of The Comparison Of The Short-term Curative Effect On The Treatment Of Early Avascular Necrosis Of Femoral Head

ObjectiveTo analysis the short-term effect of Tantalum-rod implanted method comparing withfibular graft and muscle-bone flap graft methods for early ANFH.MethodsWe chose the the early nontraumatic ANFH (Ficat Ⅱ period) patients for the study inaccordance with the Ficat stage, divided all the patients into Tantalum-rod implantedGroup, Fibular graft Group and Muscle-bone flap graft Group. The clinical data and38cases (42hips) early femoral head necrosis patients treated in our hospital from2011.02to2013.01were collected. There were27males and11females, aged26-61years (mean38years) and there were respectively14patients (15hips),12patients (15hips) and12patients (12hips) for three groups. We contrasted the preoperative Harris score and thepostoperative3months,6months,12months of three groups while observed no collapsesurvival time via imaging follow-up. Moreover, we recorded intraoperative blood loss andoperative time and analyzed the compared results.ResultsThrough the follow-up of patients at postoperative3months,6months,12monthsand the comparative analysis, we found there wasn’t significant difference (p=0.561) forthe preoperative Harris average score among three groups, while the average Harris scoresof postoperative3months,6months and12months were higher than preoperative averageHarris score (P <0.05). The operative time and intraoperative blood loss of Tantalum rodimplanted Group were significantly less than the Fibular graft Group and Muscle-bone flapgraft Group (P <0.05). The survival analysis by imaging follow-up showed that there wasnot femoral head obvious collapse for three groups and the short-term survival rate was100%. ConclusionsComparing with Fibular graft method and Muscle-bone flap graft method, theTantalum rod implanted method has several advantages, such as shorter operative time,less intraoperative blood loss, lower difficulty of operation and better shorter postoperativeefficacy.
