| Summary: | Chondroepitrochlearis (CET) is an anomalous muscular slip that originates from the pectoralis major muscle and inserts into epicondyle
of the humerus. The morphology of this variant form of pectoralis major can vary from slender to strong musculo-tendinous. In its
course, it usually crosses the neurovascular structures of arm; their compression is a major complication that could be manifested by
its persistence. In the present case, potentially anomalous CET muscle with the slender slip of origin, but strong tendinous insertion
to the medial epicondyle of the humerus was found unilaterally. This musculo-tendinous structure was found to be compressing
the brachial artery and median nerve in the arm. Detailed embryological and clinical perspective of such variant muscular slip helps
the physiotherapists, orthopaedicians in their treatment strategy in complain of restricted shoulder movement. It may also help the
neurologists, radiologists in their diagnostic approach of ulnar neuropathy. |
