Stages of Babhulkar and Babhulkar et al for Osteonecrosis of the Humeral Head

Description

Babhulkar and Babhulkar developed a staging system for osteonecrosis of the humeral head. This was developed for patients with sickle cell hemoglobinopathy. The authors are from the Medical College Sushrut Hospital and Jawaharlal Nehru Medical College in India.

Parameters on imaging studies:

(1) densities

(2) bony changes (separation, fragmentation and/or collapse)

(3) articular changes

Densities	Bony Changes	Articular Changes	Stage
none	none	none	0
spotty in subchondral region with irregularities	none	none	I
rim-like area in juxta-articular portion; may have larger densities	no chondro-osseous separation	none	II
increased density	obvious cleavage (chondro-osseous separation) with crescent sign	none	III
increased density	fragmentation without change in contour of the femoral head	none	IV
NA	mild collapse	mild irregularities	V
NA	moderate to severe collapse	hypertrophic changes	VI
