The present study was conducted on the dried specimens of adult clavicles (118) and first ribs (184) of Indian origin. The various patterns of attachment area of costoclavicular liga-ment on clavicle were depressed and rough (30.97%), flat and rough (28.32%), elevated and smooth (19.47%), elevated and rough (9.73%), flat and smooth (6.19%) and depressed and smooth (1.77%). 3.54% clavicles showed no impression on the ligamentous area. On first rib the corresponding area was elevated and rough (50.54%), elevated and smooth(16.31%) flat and rough (15.22%) and flat and smooth(17.93%).64.29% of ossified costal cartilages showed elevated and rough type of pattern .The smooth, elevated and circumscribed im-pressions were considered as faceted apophysis. It was concluded that the most common type of pattern on clavicle was depressed and rough and corresponding to it the most com-mon pattern on first rib was rough elevation. At times, these normal morphological variants may be misinterpreted as pathological in radiological images.
