Outcomes of Core Decompression for Avascular Necrosis Femoral Head: Ficat I, II or III

Abstract

Background: Treatment for osteonecrosis is still difficult, and it frequently affects young people who aspire to lead active lifestyles. The  aim of the present study was to evaluate the clinical and radiological outcomes of core decompression for Ficat stage I, II or III femoral  head avascular necrosis.

Methods: This interventional clinical trial included 30 hips in 18 patients with avascular necrosis (AVN) of  femoral head Ficat type I, II or III, conducted at Orthopedic department, Zagazig University Hospitals. Preand post-operative clinical  evaluation and radiological assessment were applied.

Results: There was a statistically significant increase in the Harris Hip scores. There  was a highly statistically significant decrease in the Modified Kerboul angle. There was a statistically significant negative correlation  between the improvement in Harris Hip scores and each of BMI, Ficat stage, and post-operative Modified Kerboul angle as an increase in each of them was associated with decreased percent of improvement.

Conclusions: Core decompression when performed before  femoral head collapse has been advocated as an efficient technique to stop or delay the progression of the disease in young individuals.
