In radiology, the Terry Thomas sign is a scapholunate ligament dissociation on an anteroposterior view of the wrist. 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. A gap of more than 3mm is pathognomonic for scapholunate dissociation.

A static instability is generally readily visible, but a dynamic scapholunate instability can only be seen radiographically in certain wrist positions or under certain loading conditions, such as when clenching the wrist, or loading the wrist in ulnar European Journal of Radiology, Volume 92 p. 45- 50 Scapholunate dissociation (SLD) is a form of carpal instability, caused by rupture of the scapholunate ligament (SLL) the secondary stabiliser of the scapholunate (SL) compartment. The treatment of scapholunate dissociation remains controversial. Although good to excellent results have been reported using a variety of surgical techniques, they have often not been confirmed by other authors. Limited wrist mobility and the likelihood that degenerative changes will progress appea … 10.1055/b-0034-77597 10 Carpal LigamentsSchmitt, R. The carpal ligaments guarantee stability of the carpal joints while allowing considerable freedom of movement in these joints of complex construction.

Scapholunate dissociation radiology

Scapholunate (SL) instability is the most common dissociative carpal instability condition. It is the most frequent cause of wrist osteoarthritis, defined as scapholunate advanced collapse or SLAC wrist. Familiarity with the SL ligament complex is required to understand the various features of SL in … The dorsal scapholunate ligament is completely or partially visible in 78% of normal wrists. Its detection following injury may help to exclude the possibility of scapholunate dissociation. There is a quite wide variation in scapholunate interval widths on sonography and an unpredictable response with stress testing.

A scapholunate dissociation (SLD), which progresses through several stages, finally ends as a perilunate dislocation. The injury can be completely ligamentous or can be a combined fracture and ligamentous injury. SLD is one of the most common types of carpal instability. Often overlooked, it may lead to weakness and arthritis.

Most commonly a result of a fall on the Imaging tests such as X-ray, MRI or CT-scan may be ordered. Diagnosis is confirmed through evidence of the following: Instability of the ligaments supporting the 1 Oct 2008 Discuss the significance of carpal injuries and the role of imaging in of the tuberosity and avulsion of the proximal pole by a scapholunate ligament. A sign of an early stage of perilunate dislocation may be wideni Thirty-two consecutive patients who had routine x-ray films were examined 12 days after wrist injury because of persistent signs and symptoms of wrist scapholunate ligament, scapholunate dissociation, combined radius-wrist than really diagnosed by means of clinical and radiologic signs [8,9].

Its features, however, also have been observed in patients with idiopathic calcium pyrophosphate dihydrate (CPPD) crystal deposition disease. European Journal of Radiology, Volume 92 p. 45- 50 Scapholunate dissociation (SLD) is a form of carpal instability, caused by rupture of the scapholunate ligament (SLL) the secondary stabiliser of the scapholunate (SL) compartment. Measurement of the scapholunate distance is used as one of the indicators for carpal instability.

The Terry Thomas (or Madonna) sign is given to the increase in the scapholunate space identified on an AP radiograph. The increased distance indicates scapholunate dissociation. 3 article feature images from this case 16 public playlist includes this case Scapholunate dissociation (SLD) represents first stage in spectrum of perilunate dislocations described by Mayfield et al Rupture of the SLIL leads to varying degrees of Volar flexion, ulnar deviation, and pronation of the scaphoid Extension, supination, and radial deviation of the lunate and triquetrum Scapholunate advanced collapse (SLAC), commonly known as SLAC wrist, refers to a pattern of wrist malalignment that has been attributed to post-traumatic or spontaneous osteoarthritis of the wrist.
