Gilula's lines

Gilula's Lines are three arcs that are normally seen on a posteroanterior view of the wrist on radiography. These lines are formed by the proximal and distal rows of the carpal bones and are used to assess the alignment of the carpal bones. Any disruption of these lines can indicate a carpal dislocation or subluxation.

Overview

Gilula's lines are named after Dr. Norman Gilula, a radiologist who first described them. They are used in the evaluation of wrist injuries to identify subtle fractures or dislocations that may not be immediately apparent on radiography. The three arcs are formed by the proximal convexities of the scaphoid, lunate, and triquetrum (first arc), the distal convexities of the same bones (second arc), and the proximal convexities of the capitate and hamate (third arc).

Clinical Significance

Disruption of Gilula's lines can indicate a variety of wrist pathologies, including scapholunate dissociation, lunate dislocation, and perilunate dislocation. These conditions can result in significant pain and disability, and early detection is crucial for optimal treatment outcomes.
