Struthers’ Ligament and Supracondylar Humeral Process: an Anatomical Study and Clinical Implications
نویسندگان
چکیده
OBJECTIVE The objective of this study was to determine the frequency and anatomical characteristics of Struthers' ligament and the supracondylar humeral process and evaluate the clinical implications in compressive neuropathy of the median nerve . METHOD We dissected 60 arms from 30 cadavers (26 males and 4 females): 15 were previously preserved in formalin and glycerin and 15 were dissected fresh in the Anatomy Laboratory for this paper. The relationships between Struthers' ligament and the median nerve and brachial artery and veins were documented with drawings and photos . RESULTS The supracondylar humeral process was not found in any of the 60 dissected arms. Struthers' ligament was identified in six arms (two bilateral); in all cases high insertion of the pronator teres muscle was observed . CONCLUSION Struthers' ligament is an aponeurotic structure that may or may not be associated with the supracondylar humeral process, and is an important potential site of median nerve compression in the lower third of the arm. Level of Evidence IV, Case Series.

Variability of the pronator teres muscle and its clinical significance.
While investigating the cause of entrapment syndrome of the peripheral nerves in the elbow region, we observed variability of the pronator teres muscle and the relationship of this muscle to the median nerve and the surrounding vessels. Attention was also paid to the occurrence of the supracondylar process of the humerus and Struthers' ligament with regard to their ontogenetic and phylogenetic ...
متن کاملUnusual high-origin of the pronator teres muscle from a Struthers' ligament coexisting with a variation of the musculocutaneous nerve.
During routine anatomical dissection of the right upper extremity of a 53-year-old woman cadaver, an unusual high-origin of the pronator teres muscle was discovered. The fibers of the aberrant muscle arose from two bone origins--the medial epicondyle and a small supracondylar process of the humerus, and from a tendinous arch (Struthers' ligament) extending between them. In addition, there was a...
متن کاملOssification of Caroticoclinoid Ligament in a Human Skull: A Case Report
The Anterior Clinoid Processe (ACP) and Middle Clinoid Process (MCP) are sometimes connected by an osseous bridge formed by ossification of Carotico-clinoid Ligament (CCL), converting the distal end of carotid sulcus into an ostium called the Carotico-clinoid Foramen (CCF). Through the CCF passes one of the segment of Internal Carotid Artery (ICA). The CCF is the result of ossification of eithe...
متن کاملStruthers' ligament and associated median nerve variations in a cadaveric specimen.
A Ligament of Struthers has been identified and studied in a cadaveric arm. Its relationships to a rudimentary supracondylar process, the pronator teres muscle, the median nerve, and the medial epicondyle of the humerus are described. Compared to an extensively studied series of normals, the ligament in this case was associated with abnormally proximal branching of the median nerve, a finding w...

Background: The most common pediatric elbow fracture is supracondylar humeral fracture which accounts for 60% ofelbow fractures in children. The aim of this study was to evaluate the results of open reduction and internal fixation oftype III supracondylar humeral fractures using a Triceps sparing posterior approach.Methods: In total, 98 patients were evaluated from June 2007 t...
