APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Altman et al’s1 criteria included hip internal rotation less than 15° and an age of over 50 years. Age appears to be the main factor that limits using Berma-Zeinstra et al’s3 and Altman et al’s1 specific criteria for clinical diagnosis of hip osteoarthritis, because our patient was under 50 years old.

Detailed explanation-2: -grade 1: possible joint space narrowing and subtle osteophytes. grade 2: definite joint space narrowing, defined osteophytes and some sclerosis, especially in the acetabular region. grade 3: marked joint space narrowing, small osteophytes, some sclerosis and cyst formation and deformity of femoral head and acetabulum.
