Materials and Methods: The case-control strategy of this study was carried out on 30 patients with fracture of femur neck and having total hip arthroplasty. For control group, 5 samples of femur head were collected from normal individuals. Samples were fixed in 10% formalin and then sliced into 6 segments. Therefore, radiological examination was performed and according to Jeffery and Meachim methods were scored into normal and grades 1-4. After decalcification, two mid-coronal sections were done on each segment and through dehydrating and blocking in paraffin, they were stained by hematoxylin and eosin. For measurement of thickness of articular cartilage, an ocular graticule (#18) was used. For statistical analysis, t-test was applied. Results: This study was performed on 5 samples of femur head of normal cadavers with an average age of 26.4±2.7 and 30 patients including 20 cases with fracture of femur neck and 10 cases with osteoarthritis and have undergone a surgical operation. Thickness of femur head was less in patients with osteoarthritis compared to control group. There was no significant difference between case and control groups regarding anterior portion of femur head. Thickness of cartilage in middle and posterior portions in control group was 2.12±0.55 (0.52±0.83 according to scoring, P }, URL = {http://feyz.kaums.ac.ir/article-1-364-en.html}, eprint = {http://feyz.kaums.ac.ir/article-1-364-en.PDF}, journal = {Feyz Medical Sciences Journal}, doi = {}, year = {2001} }
