ABSTRACT
Aim: To study the clinical and radiological outcome of
unstable intertrochanteric fracture AO/OTA 31A2, 31A3 fixed by proximal femoral
nail antirotation
Study design: Descriptive cross sectional study.
Place and duration
of study: Department of Orthopedic Surgery and
Traumatology, Pir Abdul Qadir Shah Jilani Institute of Medical Sciences,
Gambat, Sindh from 1st January 2016 to 31st December
2019.
Methodology: Forty four cases having intertrochanteric fracture
AO/OTA 31A2, 31A3 with age ranging from 18 year to 55 year of either gender
were selected; patients having close fracture, who were willing were included
in the study, while patients older than 55 year and younger than 18 year,
AO/OTA 31A1 fracture, open fracture, bilateral injuries, smoker, alcoholic,
drug addicted, poly-trauma, pathological fracture and history of poor
compliance, psychiatric disease were excluded.
Results: There were 26(59.09%) males and 18(40.91%) females with mean age was
41.3±7.7 years. Regarding classification; AO/OTA 31A2 were 33 (75%), and 31A3
were 11 (25%). Mean time for union was 18.5±3.55 weeks. The average time of
follow-up was 48.5±6.6 weeks. Harris Hip Score was excellent (90-100) in
31(70.45%), good (80-89) in 7(15.91%), fair (70-80) in 3 (6.81%) and poor
(<70) in 3 (6.81%).
Conclusion: Intramedullary device proximal femoral nail
antirotation can be labelled as implant of choice for unstable
intertrochanteric fractures AO/OTA 31A2, 31A3, with fruitful clinical and
radiological outcomes, and with fewer complications. Hip Harris score was
excellent-good in 86% of the patients.
