accompanied by a scaphoid fracture 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. SLD can cause osteoarthritis of the wrist.

Importantly, there is widening of the scapholunate distance (Terry Thomas sign) consistent with scapholunate dissociation.

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.

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. There is an intra-articular radial styloid fracture. Importantly, there is widening of the scapholunate distance (Terry Thomas sign) consistent with scapholunate dissociation. These findings represent scapholunate dissociation (rotatory subluxation of the scaphoid), and is the mildest form of this injury; Case B-D Case 7B showed a transcaphoid perilunate dislocation; note that the lunate and radius remain normally aligned. This injury is 2-3x more common than a lunate dislocation. accompanied by a scaphoid fracture 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.

Dorsal intercalated segment instability (DISI) is a related carpal malalignment pattern whic… The scapholunate joint is essential to carpal function. 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. X-ray.
