increased in scapholunate dissociation; increased in dorsal intercalated segmental instability with Hand⎪Scapholunate Ligament Injury & DISI 11 Oct 2020 · The Orthobullets Podcast In this episode, we review the high-yield topic of Scapholunate Ligament Injury & DISI from the Hand section. The scapholunate is an interosseous carpal ligament that provides stability to the proximal carpal row. It consists of dorsal, proximal and palmar segments that bridge the scaphoid and lunate. When the ligament complex tears, the scaphoid tends to flex while the lunate extends, creating translational and rotational instability between the two.

The scapholunate is an interosseous carpal ligament that provides stability to the proximal carpal row. It consists of dorsal, proximal and palmar segments that bridge the scaphoid and lunate. When the ligament complex tears, the scaphoid tends to flex while the lunate extends, creating translational and rotational instability between the two. Scapholunate dissociation: Involves a complete tear of the SLIL with additional tear of 1 or more secondary ligaments.

deformity. Materials and Methods: Retrospective case series of 11 patients with a mean age of 45 years were treated by the senior author 7 months after SL injury.

X rays in lunate and perilunate dislocations are often not as clear and obvious as the diagrams used to teach these injuries. 2015-10-07 · Stage I- Scapholunate dislocation noted on PA of wrist film with increased space between scaphoid and lunate; Stage II & III –Perilunate dislocations; Stage IV-Lunate dislocation; The main differentiating factor between perilunate and lunate dislocation is the lunate’s articulation with the radius.

Stage II describes displacement of the carpus relative to the lunate. The lunocapitate articulation may be disrupted resulting in a dorsal perilunate dislocation, or in the case of concomitant scaphoid fracture, the wrist may undergo a transscaphoperilunate dislocation. There is an intra-articular radial styloid fracture.

The lunocapitate articulation may be disrupted resulting in a dorsal perilunate dislocation, or in the case of concomitant scaphoid fracture, the wrist may undergo a transscaphoperilunate dislocation. There is an intra-articular radial styloid fracture. Importantly, there is widening of the scapholunate distance (Terry Thomas sign) consistent with scapholunate dissociation.

carpal instability dissociative (cid) 2. carpal instability A needle was inserted into the right radioscaphoid joint. Iodinated contrast mixed with gadolinium was injected into the right radioscaphoid joint. The contrast extended into the mid carpal joints suggesting a disruption of the scapholunate ligament. The patient was then sent to MRI. Reduction and Association of the Scaphoid and the Lunate for Scapholunate Instability Joseph M. Lombardi James A. Wilkerson Melvin P. Rosenwasser DEFINITION Scapholunate instability occurs as a result of injury to the scapholunate interosseous ligament (SLIL) and represents the most common type of carpal instability. Instability can be categorized based on physical and radiographic findings.… Scaphoid non-union advanced collapse (SNAC) is a complication that can occur with scaphoid fractures, specifically non-union of scaphoid fractures.It is essentially the same sequela of wrist injury causing scapholunate dissociation as seen in scapholunate advanced collapse (SLAC).

Scapholunate dissociation (SLD) is the most common type of carpal instability. It is the most common instability pattern because the intercarpal motion during flexion and extension cross at the scapholunate interface.
