MORPHOLOGICAL STUDY OF ATTACHMENT OF COSTOCLAVICULAR LIGAMENT ON THE CLAVICLE IN SOUTH INDIAN POPULATION
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 33
Abstract
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
