Deep learning approach to femoral AVN detection in digital radiography: differentiating patients and pre-collapse stages.

Objective: This study aimed to evaluate a new deep-learning model for diagnosing avascular necrosis of the femoral head (AVNFH) by analyzing pelvic anteroposterior digital radiography.

Methods: The study sample included 1167 hips. The radiographs were independently classified into 6 stages by a radiologist using their simultaneous MRIs.

The results of biplanar distal femoral osteotomy; a case series study.

Background: Distal femur wedge osteotomies for varus or valgus alignment of the lower extremity could be done in either uniplanar or biplanar fashion.Union time and stability of the osteotomy site has been considered important in this anatomic region. In this study, clinical and radiographic findings of biplane distal femur osteotomy were reported.
