Hartofilakidis Classification (Hip Dysplasia)
Hartofilakidis classification of adult developmental dysplasia of the hip — the second widely used adult-DDH classification alongside Crowe, grading the hip by the relationship of the femoral head to the true acetabulum.

Example
- Hartofilakidis type
- Type B - low dislocation (false acetabulum partially overlaps)
Result: Hartofilakidis type B (low dislocation): the femoral head forms a false acetabulum that partially overlaps the true acetabulum.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Type A
- Dysplasia: the femoral head is within the true acetabulum despite subluxation; segmental superior-wall deficiency.
- Type B
- Low dislocation: the false acetabulum partially overlaps the true acetabulum; complete absence of the superior wall.
- Type C
- High dislocation: the false acetabulum has no connection with the true one; the head is completely uncovered.
