Purpose: The good of this survey was to analyze the epidemiological aspects and evaluate anatomical and functional results of the treatment by screwing of femoral neck fracture in adulthood at the Teaching Hospital of an underequipped country. Material and Methods: This is a retrospective study from January 1, 2011 to December 31, 2015, concerning patients hospitalized for fractures of femoral neck and having been operated by screwing. The variables studied were epidemiological and therapeutic aspects. Anatomical results were examined on standard x rays of the pelvis in front and the hip in profil, based on the consolidation of the bony axis. Functional results were analyzed according to the quotation of Postel Merle D’Aubigné. Results: Eleven screwings of femoral neck have been done to 11 patients (9 men and 2 women), average age was 47 years (29 and 60 years) from January 2011 to December 2015, at the mean recoil of 19 months (12 and 24 months). Amongst consolidated patients (n = 7), one patient presented a necrosis of femoral head at two years hindsight. Four patients presented an aseptic pseudarthrosis of femoral neck, or a bad anatomical result. Amidst this group of patients, one underwent a joint replacement type Moore and suggestion of intermediary prothesis was recommended to three patients. According to the quotation of Postel Merle D’Aubigné, results were very satisfactory to 5 patients, good to 2 patients and bad to 4 patients. According to the score of Parker, 7 patients presented a score of 9 and 4 patients a score of 7. Conclusion: The treatment of femoral neck fractures in adulthood requires a surgical approach by osteosynthesis and must be precocious before 24 hours in order to reduce risks of pseudarthrosis of femoral neck and necrosis of femoral head.
