ABSTRACT
Background: The proper treatment of Avascular Necrosis(AVN) of Femoral Head has become a major challengeworldwide in younger age group as they are main effectiveforce of family and society. The patients who are young andsuffer from AVN of femoral head become immovable, worklessand unproductive. Thus they become burden to family andsociety. The Hip Replacement is a better way of treatment forthis type of patients, making them pain free and movable andimproving their everyday activity.Objective: To evaluate outcome of non-cemented total hiparthroplasty in avascular necrosis of femoral head among theactive younger age group of patients.Method: This was a prospective observational study of 30patients and all the patients had done non-cemented total hiparthroplasty (THA) through lateral approach at the NationalInstitute of Traumatology and Orthopaedic Rehabilitation(NITOR), Dhaka.Results: Mean age of the patients was 32 ±5.12 years,patients were diagnosed as Avascular Necrosis of FemoralHead in which 63% were affected at Right sided Hip 37%patients were at Left sided hip. Final outcome after six monthsof operation evaluated with Modified Harris Hip Score revealedthat, there was significant (p<0.005) improvement in functionalability of the patients after THA. Among the 30 studied cases,21 (70%) patients carried slight pain and 63.4% of them wereable to walk unlimitedly. Outcome of supporting functionanalysis indicated 76.7% patients could walk and climb stairswithout support and 100% patients could sit on chair, 66.7%patients among them could walk without limping. On clinicalassessment of deformity, range of motion before and afteroperation, significantly resolved the deformities and increasedthe range of motion (2100-2300). After evaluation with ModifiedHarris Hip Score showed that 60% excellent (HHS 90-100),30% good (HHS 80-89), 10% had fair (HHS 90-100) outcome.Conclusion: The progressive study of the patients of THAshowed that non-cemented THA has resulted in a better wayamong the younger age group of people
