Answer 24

Replacement of the femoral head and acetabular surface

RA, OA, Osteonecrosis, Fractures, Pain, Tumors

Answer 28

Non-inflammatory, self-limting syndrome where the femoral head becomes flattened at weight bearing surface secondary to avascular necrosis Typically in children 4-8

Question 29

PT for Legg-Calve

Answer 29

Regain motion and reduce pain dysfunction and strengthen all around hip and LE on both legs. Gradually progress based on pain tolerance.
