Background: Bicipital groove (BG) is defined as an indentation present on the anterior aspect of upper end of humerus. Morphometry of BG is known to play important role in maintaining the stability and function of shoulder joint during multidirectional biomechanical movement of arms. Therefore, knowledge regarding detailed osseous anatomy of BG is essential for better understanding of variety of causes of shoulder pain and disability. Aim: The goal of the present study was to describe the detailed morphometric features of BG in dry humerii of West Bengal population and also to correlate its clinical implications through literature review. Materials and Methods: The study was undertaken on 107 dry human humerii of unknown age and sex without any gross pathology collected from different medical colleges of West Bengal. Total length, antero-posterior and transverse width of humerii at surgical neck along with length, width, depth, medial wall and opening angles of BG were measured. Data obtained were statistically analyzed. Finally, results were compared with other similar type of studies.
BACKGROUND: Accurate knowledge of anatomical variations regarding origins of the profunda femoris, medial and lateral femoral circumflex femoral arteries are important for clinicians in the present modern era of interventional radiology. Our aim of this study was to observe and identify the variations in origin of the Profunda femoris artery and its circumflex branches. MATERIALS & METHODS: 66 femoral triangles were dissected on 33 cadavers (Both sides). The profunda femoris vessel and its medial and lateral circumflex arteries were dissected and identified. The distance of the site of origin of Profunda Femoris Artery was measured from mid-inguinal point (MIP) in centimetres with scale, thread, and digital callipers. The sites of origin of Medial Circumflex Femoral Artery and Lateral Circumflex Femoral Artery were also studied and the distances of origin of each of them were measured from the origin of the Profunda Femoris Artery and from the mid-inguinal point. All the data were interpreted in tables. RESULTS: The data from the study was analyzed using statistical methods and analyzed by using the statistical package SPSS (Statistical Package for Social Sciences) version 16.0 for windows in present study for analyzing the data contingency table were created first and then analyzed by using the Pearson's chi-square test. The present study encountered that, in approximately 50% cases the profunda femoris artery originated from the lateral aspect of the common femoral artery. The lateral and medial circumflex femoral artery commonly originated from the profunda femoris nearly close to its origin from common femoral artery. CONCLUSION: This knowledge of variation and position would be very useful in preventing the iatrogenic injury to these vessels during surgical procedures of the femoral triangle. So, this study would be useful for the clinician for surgical and therapeutic intervention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
