Supracondylar process of the humerus
Supracondylar Process of the Humerus
The Supracondylar Process of the Humerus is a bony spur or projection that is occasionally found on the humerus, the long bone in the upper arm. It is a rare anatomical variant that is present in approximately 1% of the population.
Anatomy[edit]
The supracondylar process is located on the anteromedial surface of the humerus, approximately 5 cm above the medial epicondyle. It is typically connected to the medial epicondyle by a thin band of fibrous tissue known as the ligament of Struthers, forming a canal through which the median nerve and brachial artery may pass.
Clinical Significance[edit]
Although the supracondylar process is usually asymptomatic, it can occasionally cause neurovascular compression syndrome, leading to symptoms such as pain, numbness, and weakness in the arm. This is known as Pronator Teres Syndrome or Struthers' Syndrome.
History[edit]
The supracondylar process was first described by the Scottish anatomist Sir John Struthers in 1848. He also described the associated ligament, which is now known as the ligament of Struthers.
