Introduction: In patients less than 60 years of age, even with displaced femoral neck fractures, head preservation using early closed reduction and internal fixation (CRIF) with multiple annulated hip screws (CHS) is one of the accepted methods of treatment. Though union rate is improved, vascular impairment of the head following this fracture, resulting in osteonecrosis, remains as an unsolved problem. Aims: The incidence rate of osteonecrosis, whether they are same across groups, or higher in one of the groups and the incidence rate of union and non-union, whether they are same across groups, or higher in one of the groups. Materials and Methods: The present study was a Case-control/ Retrospective study study. This Study was conducted from June 2020 to June 2022 at Department of orthopaedic, kumar hospital and research institute, Khemnichak, patna, Bihar 27. Result: In CHS + bone graft Group, 35 (77.8%) patients were Excellent Final MHSS, 8 (17.8%) patients were Good Final MHSS and 2 (4.4%) patient were Poor Final MHSS Grading. Conclusion: From the discussion submitted above it is clearly evident that till date we could not give a satisfactory treatment to our patients of displaced femoral neck fractures and this is more relevant for younger patients of less than 60 years of age for whom we cannot advise THA.
