When there is rotation of the scaphoid as can occur with scapholunate dissociation (widening of distance between scaphoid and lunate to greater than 3 mm), (yellow arrow), a ring-shaped density can appear as a sign of foreshortening (white arrow). 2017-07-01 The importance of radiographic evaluation of the scapholunate space, which should not be wider than 2 mm, has been well established in cases of wrist injury. Unfortunately, the assessment of this space is not accurately determined with routine posteroanterior (PA) radiographs, because the scaphoid and lunate bones often overlap. Tomas A. Scapholunate Dissociation.

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. doi:10.2519/jospt.2018.7774.

Abnormal widening is indicative of injury to the scapholunate ligament that occurs with scapholunate dissociation . 2015-12-21 These findings represent scapholunate dissociation (rotatory subluxation of the scaphoid), and is the mildest form of this injury.

Radiation risk and cost-benefit analysis of a paediatric radiology procedure: Arthrodesis for chronic static scapholunate dissociation: a prospective study in 12  dislocation lunate perilunate carpal instability radiopaedia mayfield radiology lateral classification fracture wrist dislocations scapholunate dissociation imaging  Scapholunate dissociation, also known as rotary subluxation of the scaphoid, refers to an abnormal orientation of the scaphoid relative to the lunate, and implies severe injury to the scapholunate interosseous ligament and other stabilizing ligaments. 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.

The increased distance indicates scapholunate dissociation. There is an intra-articular radial styloid fracture.
