Which trajectory should we choose? — Defining safe entry–target pathways and underlying femoral morphology for bone marrow injection in osteonecrosis of the femoral head
This study quantitatively identified six safe entry-target combinations and key morphological determinants influencing the permissible insertion angle. These findings provide practical anatomical reference data to support safer, morphology-based planning for ONFH treatment.
