humeroradial joint

The image depicts the left elbow joint with particular emphasis on the anterior and ulnar collateral ligaments - critical stabilizing structures that prevent excessive movement and protect the joint's integrity. These ligaments work in concert with bones, muscles, and other connective tissues to enable precise movements while maintaining joint stability during the numerous physical activities we perform daily.

The humerus, the upper arm bone, features two distal epicondyles critical for elbow joint function, but their articulations with forearm bones can confuse medical students. The mnemonic “CRAzy TULips” provides a concise and memorable way to recall that the capitulum articulates with the radius and the trochlea with the ulna. This tool aids students in mastering elbow anatomy for exams and enhances clinical understanding, particularly in diagnosing elbow injuries or planning orthopedic procedures.
