Background: Femoral neck fractures present a considerable challenge for surgeons in the field. This study focuses on a critical issue in understanding the occurrence of treatment failure among individuals who underwent surgical fixation for femoral neck fractures. 
Objectives: This study aims to evaluate the prevalence of treatment failure and identify associated risk factors in patients with non-displaced femoral neck fractures who underwent this procedure. 
Methods: Data were gathered from individuals with non-displaced femoral neck fractures who received internal fixation from 2011 to 2022, ensuring a minimum follow-up period of one year. Treatment failure was evaluated based on these data. The gathered data were documented using SPSS software, version 22 and examined using descriptive statistics, including percentage, frequency, and Mean±SD. Statistical analysis was conducted using inferential tests, such as the t-test, chi-square test, and Fisher’s exact test. P≤0.05 was considered.
Results: Data were analyzed on 60 individuals, with a mean age of 50.25±16.94 years. Of the total, 44 men (73.3%) participated. One individual (1.7%) experienced avascular necrosis (AVN), while 7(11.7%) experienced nonunion. Seven patients (11.7%) experienced treatment failure, including AVN, which was also associated with nonunion. Six cases (10%) were advanced to total hip replacement surgery. 
Conclusion: The results of this study indicate that the fixation of non-displaced femoral neck fractures has a combined incidence of nonunion and AVN at around 12%. It is advisable to consistently follow-up with patients and monitor risk factors after surgery to minimize complications and enable quicker identification of those impacted.
