Post-Operative Assessment on Gait Parameters among Intertrochanteric Femur Fracture Patients Operated by Proximal Femoral Nail Antirotation

Background: The PFNA-2 implant is designed specifically in the treatment of unstable intertrochanteric fractures for the Asians, since the implant designed in the case for Caucasians was presented with numerous complications when on application to the Asian population due to the mismatch in femoral geometry. The study intends to explore the efficacy of PFNA-2 for the treatment of intertrochanteric fractures in elderly Indian patients needs to be assessed to determine its usefulness. Gait analysis using simple Helen Hayes Protocol of 3-D Gait analyser was employed as a valuable tool for evaluating the effectiveness of PFNA-2 in treating intertrochanteric fractures in elderly Indian patients. By assessing gait parameters such as stride length, walking speed, and cadence, researchers can determine if the implant has improved the patient’s ability to walk and perform daily activities. Gait analysis can also help identify any complications or issues that may arise post-surgery, allowing for early intervention and improved outcomes. Methods: The present investigation governing the postoperative assessment was conducted among Orthopaedics inpatients and outpatients from Jawaharlal Nehru Medical College, KAHER, and Belagavi India. The study population comprised of ITF patients who underwent PFNA-2 and were taking part in the post-operative assessment of spatiotemporal parameters recorded using 3-D Gait analyser (via employing Helen Haley’s protocol) conducted between January 2021 to December 2021. Helen Hayes method was adopted for monitoring the spatiotemporal parameters. Statistical analysis was conducted using SPSS (Version 19), for analysis of the data rendered. Results: The results showed that the average time taken for one stride was 0.852 seconds, with a range from 0.66 to 1.01 seconds, and a relatively low standard deviation of 0.0784 seconds. Stance Time, which is the time spent with the foot in contact with the ground during one stride, had an average of 0.656 seconds. Swing Tim with an average of 0.456 seconds. Single Support Phase, which is the time spent with one foot in contact with the ground during one stride, had an average of 38.25% of the stride cycle, with a range from 36.12% to 40.2%, and a standard deviation of 0.827%. And the double Support Phase reported with an average of 10.927% among the study population. The mean value reported for Cadence was 106.86 steps/min. Conclusion: From the achieved outcome it could be inferred from the overall gait analysis showed better functional outcome, thereby indicating surgical efficacy of PFNA-2 among elderly population in India.
