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.
Scapholunate advanced collapse (also known as SLAC wrist) is a type of wrist osteoarthritis.SLAC wrist is the most common type of post-traumatic wrist osteoarthritis [1] and is often the result of an undiagnosed or untreated scapholunate ligament rupture. [2]
The scapholunate ligament is an intraarticular ligament binding the scaphoid and lunate bones of the wrist together. It is divided into three areas, dorsal, proximal and palmar, with the dorsal segment being the strongest part. [3] It is the main stabilizer of the scaphoid. In contrast to the scapholunate ligament, the lunotriquetral ligament ...
Kienböck's disease is a disorder of the wrist.It is named for Dr. Robert Kienböck, a radiologist in Vienna, Austria who described osteomalacia of the lunate in 1910. [1]It is breakdown of the lunate bone, a carpal bone in the wrist that articulates with the radius in the forearm.
The new articulation of the capitate with the lunate fossa of the distal radius is not as congruent as the former scaphoid-lunate-radius joint. [16] [17] This and other issues contribute to potential to develop arthritis over the years. In part based on these concerns, some surgeon prefer to maintain the lunate in patients younger than 40 years ...
To perform the test, the examiner grasps the wrist with their thumb over the scaphoid tubercle (volar aspect of the palm) in order to prevent the scaphoid from moving into its more vertically oriented position in ulnar deviation. For the test, the wrist needs to be in slight extension. The patient's wrist is then moved from ulnar to radial ...
n November 1954, 29-year-old Sammy Davis Jr. was driving to Hollywood when a car crash left his eye mangled beyond repair. Doubting his potential as a one-eyed entertainer, the burgeoning performer sought a solution at the same venerable institution where other misfortunate starlets had gone to fill their vacant sockets: Mager & Gougelman, a family-owned business in New York City that has ...
