The cervical vertebrae presents foramen transversaria in each transverse process. In all but the seventh cervical vertebra, the foramen normally transmits vertebral artery and vein and a branch from the cervicothoracic ganglion.140 cervical vertebrae were studied. Variations were noticed in the number of foramen transversarium unilaterally and bilaterally. Variations in foramen transversarium may indicate the variation in course of vertebral arteries

There are many articles reporting anomalies of various blood vessels of upper extremity. In the present article, we are reporting a case of high division of brachial artery into medial and lateral branches, 9.5 cm distal to the lower border of teres major muscle. It was also observed that the two branches are crossing over near the lower part of front of arm and the lateral branch continued into the cubital fossa and trifurcated at the proximal border of pronator teres muscle. We have discussed the anatomy, embryological basis, and clinical implications of these variations along with relevant literature review. The importance of knowledge about these variations in therapeutic and diagnostic interventions is discussed.

BACKGROUND Clavicle is an important bone concerned with movements of upper limb. It has a shaft and two ends, sternal end and acromial end. Inferior surface of the sternal end presents with an impression called costoclavicular area. The presence of costoclavicular groove for the attachment of costoclavicular ligament was studied in 78 clavicles. The most common type seen was rough and elevated. This area is clinically important for radiologists and orthopaedicians. Aim-To study the attachment of costoclavicular ligament on clavicle. MATERIALS AND METHODS A cross-sectional descriptive study was carried on 78 clavicles, out of which 27 were of right side and 51 belonging to left side of unknown age and sex. The impressions for the attachment of costoclavicular ligament were observed. Bones were obtained from the Department of Anatomy, K. S. Hegde Medical Academy, Deralakatte, Mangalore. The results were tabulated and percentages were calculated. RESULTS Inferior surface of sternal end of clavicle provides attachment for costoclavicular ligament. The impression is well-demarcated from the rest of the bone in most of the cases and invariably oval in outline and showed distinctive types of surface projection. In this study 78 clavicles comprising of 27 right and 51 left were taken and impressions were noticed, i.e. flat and smooth (FS), rough and elevated (RE), depressed and rough (DR), flat and rough (FR) and no impression. We found 6 (6.4%) flat and smooth (FS), 38 (48.7%) rough and elevated (RE), 23 (29.5%) depressed and rough (DR) and 6 (6.4%) flat and rough (FR) impressions on the clavicle. Out of 78 clavicles, 5 of them had no impressions. CONCLUSION The most common type of pattern of attachment of costoclavicular area on the clavicle is rough and elevated. The knowledge of morphological variation of costoclavicular impression area is clinically useful for radiologists and orthopaedicians.
