One Year Review Compairing Mortality Following DHS Vs PFN

Abstract

Objective: The objective of my study is to compare the mortality following DHS vs PFN. Study Design: Observational retrospective study. Place of study: Department of Orthopedic & Spine Surgery, Dr. Ziauddin Hospital. Duration: January 2020 to December 2021. Methodology: Patients were divided into 2 groups according to the surgical implant used. Group A with DHS implant, Group B with PFN and mortality is being checked in each group till 1-year post-operative time period by contacting each patient. Age, Gender, co morbidities, surgical procedure performed, fracture pattern (extracapsular, intracapsular) time of injury data was collected from registry of the hospital after taking permission from the authorities involved. Results: The study included 94 patients. Minimum age was 40 years and maximum age was 95 years, and mean age was 71.11. Out of which 61 (64.8%) patients are included in group A in which DHS was done, 33(35%) patients in group B with PFN implants, (Table 1) Mean age in group A is 72.9 (SD 14.0), group B 67.7 (SD 13.3), (Table 1) In group A 16 patients (26.2%) had mortality within 1 year. In group B 2 patients (6%) has mortality within 1 year. (Table 2) There is significant association of increased mortality in patients with DHS implants (group A) with p value <0.005. (Table 2) Mortality was raised in males that is 10 (22.7%) and in females 8 patients (16%). However, no significant association was found p(0.33). (Table 3) Out of 94 patients 54 patients are ASA III with multiple comorbid and other are ASAII and ASA I. Mortality was higher in patients with ASA III 54 patients (57%) and it was not statistically significant with p (0.168). (Table 4) Conclusion: This study shows increased mortality in patients with DHS implants as compared to patients with PFN implants.
