ABSTRACT
Introduction: The Scapula is a large, flat, triangular bone which lies on the posterolateral aspect of the chestwall. The Suprascapular notch is a depression on the superior border of the scapula which gives passage toSuprascapular nerve. Anatomical variations of the shape and size of notch is useful as it is the common site ofSuprascapular nerve entrapment syndrome.Materials and Methods: The present study was carried out on 60 adult dry human Scapulae. Different shapes ofSuprascapular notch was observed, then vertical and transverse dimensions of the notch were measured.Results and Conclusion: Based on Rengachary classification, type III notch was found to be most common.Suprascapular foramen was observed in 5 Scapulae. The mean vertical and transverse diameters were measuredas 6.43mm and 9.81mm respectively. The study of morphology and morphometry of Suprascapular notch helpsto correlate Suprascapular nerve entrapment with specific type of notch.
ABSTRACT
Many formative variations of median nerve are known but this variant formation and course of median nerve israre. A variant formation of median nerve was noted in the axilla and arm of a male cadaver, in the form offormation of median nerve behind the third part of axillary artery and brachial artery wind around mediannerve. There may be compression of the nerve passing around the artery. This variation may be clinicallyimportant because symptoms of median nerve compression arising from similar variations are often confusedwith more common causes such as radiculopathy and carpal tunnel syndrome.During routine dissection, one of the cadaver showed bilateral abnormal course of brachial artery in the arm. Inthe right arm: In the axilla, median nerve present posterior to the artery. In the left arm: brachial artery twistingaround the median nerve. At the level of the neck of radius brachial artery dividing into radial and ulnar arteriesin both side of upper limb.
