A fist X-ray of a scapholunate ligament rupture will show a descending capitate bone. Making a fist will give pressure at the capitate, which will descend if there is a rupture in the scapholunate ligament.
The PA wrist x-ray will demonstrate sclerosis and joint space narrowing between the lunate and capitate. Over time, the capitate will migrate proximally into the space created by the scapholunate dissociation. [2] The radiographic findings in Stage III SLAC wrist are synonymous with the Terry-Thomas sign, indicating complete scapholunate ...
In radiology, the Terry-Thomas sign is a scapholunate ligament dissociation on an anteroposterior view of the wrist. [1] [2] Most commonly a result of a fall on the outstretched hand , the scapholunate ligament ruptures resulting in separation of the lunate and scaphoid bones. This burst causes the scaphoid bone to dorsally rotate. [3]
Because SLAC results from scapholunate ligament rupture, there is a larger space between the two bones, also known as the Terry Thomas sign. [10] Scaphoid instability due to the ligament rupture can be stactic or dynamic. [11] When the X-ray is diagnostic and there is a convincing Terry Thomas sign it is a static scaphoid instability.
Its position is the intersections of the long axes of the four fingers while in a fist, or the base of the thenar eminence. When palpated in this position, the bone will be felt to slide forward during radial deviation (wrist abduction) and flexion. Clicking of the scaphoid or no anterior translation can indicate scapholunate instability.

Joints of the hand, X-ray Interphalangeal ligaments and phalanges. Right hand. Deep dissection. Posterior (dorsal) view. The PIP joint exhibits great lateral stability. Its transverse diameter is greater than its antero-posterior diameter and its thick collateral ligaments are tight in all positions during flexion, contrary to those in the metacarpophalangeal joint.
Whether you call it the clenched fist, Black Power fist, BLM fist, or solidarity fist, one thing is clear: it’s used as a symbol of Black pride, solidarity, and dedication to fighting injustice.
