Femoral Neck System (FNS): A Biomechanical Strong Solution for Stable Fixation in Basi cervical Neck of Femur Fractures
Abstract
Background: Due to their rarity and probable instability, basicervical femoral neck fractures whose frequency ranges from 1.8 to 7.6% present difficulties and have higher repair failure rates than intertrochanteric fractures. Even though the fracture site is extracapsular, surgical treatment is still difficult. Objectives: This study was done for assessment of femoral neck system (FNS) as a biomechanical strong solution for stable fixation in basicervical neck of femur fractures. Methods: The cross-sectional Observational study was conducted in the Department of Orthopedic, National Institute of Traumatology and Orthopedic Rehabilitation (NITOR) from June 2022 to May 2023. A total of 30 patients of both sexes were included in the study. Data was collected over a period of 12 months and analyzed by appropriate computer based programmed software Statistical Package for the Social Sciences (SPSS), version 24. Results: In this study, most of the respondents 18 (60.7%) lies between 51 years to 60 years. Mean ± SD of the respondents was 52.41 ± 6.75 years. More than half of the patient 19 (63.30%) were male and 11 (36.70%) patients were female. Most of the patients 17 (56.7%) BMI were in between normal range, 7 (23.3%) were underweight and 6 (20.0%) were overweight. Mean ± SD of the patients BMI was 25.3 ± 5.4 kg/m2. About 12 (40.0%) patients had type III garden fracture, 9 (30.0%) patients had type II garden fracture, and 9 (30.0%) patients had type I garden fracture. Most of the patients 21 (70.0%) had type II Pauwels fracture. The average surgery time was 76.65 ± 34.25 min, the blood loss was 67.45 ± 51.43 ml, the Preoperative Harris Score was 22.25 ± 4.56 and the Postoperative Harris Score was 83.80 ± 5.78, the healing time was 3.33 ± 0.60 and Femoral neck shortens was 2.20 ± 1.41mm. Non-union had occurred in case of 3 (10.0%) patients, Femoral neck shortening had occurred in 2 (6.7%) case and Femoral neck necrosis had occurred in 1 (3.3%) case. Conclusion: FNS treatment can produce good clinical outcomes for patients with basi cervical femoral neck fractures. FNS exhibits much greater overall construct stability and superior biomechanical qualities. Key words: Femoral neck system, Femoral neck fracture, Harris Hip Score, Surgical fixation devices
