There are two. 17 Mar 2009 Early clinical and radiological presentation may be subtle; hence an understanding of wrist biomechanics is vital in early diagnosis and treatment. Scapholunate dissociation, also known as rotary subluxation of the scaphoid, refers to an abnormal orientation of the scaphoid relative to the lunate and implies 21 Dec 2015 Case Report : 23 yr old lady with clinical scapholunate dissociation on MRI shows ill definition of scapholunate ligament (volar component MRI, and frontal radiograph (C) of the wrist demonstrating scapholunate dissociation.

diastasis of the scapholunate complex occurs with complete SLIL tears and capsule disruption. Associated injuries. DISI (dorsal intercalated segmental instability) scapholunate dissociation causes the scaphoid to flex palmar and the lunate to dorsiflex; if left untreated the DISI deformity can progress into a SLAC wrist Townsville radiology training.

CT. Loading Stack -. 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 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 interval. The scapholunate interval is the radiographic measurement of the scapholunate joint on PA wrist projections. Abnormal widening is indicative of injury to the scapholunate ligament that occurs with scapholunate dissociation .

Scapholunate advanced collapse (SLAC) Scapholunate Dissociation. There is increased distance of greater than 5 mm (black arrow) between the scaphoid (S) and the lunate (L) producing the so-called Terry Thomas or David Letterman sign. For these same photos without the arrows, click here For more information, click on the link if you see this icon The scapholunate interval is the radiographic measurement of the scapholunate joint on PA wrist projections. Abnormal widening is indicative of injury to the scapholunate ligament that occurs with scapholunate dissociation. On radiographs, findings that are suspicious for scapholunate dissociation are widening of the scapholunate interosseous space greater than 2-4 mm, the scaphoid ring sign, an increased scapholunate angle that is greater than 60 degrees, and the palmar V sign, as described previously. 2 Scapholunate misalignment on both static and stressed radiographs is defined as static scapholunate instability.

This injury is 2-3x more common than a lunate dislocation. On radiographs, findings that are suspicious for scapholunate dissociation are widening of the scapholunate interosseous space greater than 2-4 mm, the scaphoid ring sign, an increased scapholunate angle that is greater than 60 degrees, and the palmar V sign, as described previously. 2 Scapholunate misalignment on both static and stressed radiographs is defined as static scapholunate … A scaphoid radiograph series, consistent with American College of Radiology guidelines, was obtained based upon examination findings. The radiographs revealed a scapholunate gap of 4 mm and a scapholunate angle of greater than 60°, suggestive of scapholunate dissociation. J Orthop Sports Phys Ther 2018;48(3):225.
