This article has been cited by other articles in PMC. We propose that two mechanisms exist which may lead to AVN of the lunate; either as a localized or global lunate phenomenon. Open in a separate window.

For which of the depicted conditions is temporary scaphotrapeziotrapezoidal pinning most indicated? The articular surfaces are the interfaces that allow motion and transmit the load from their column. B Reformatted image of the same lunate, superimposed on a normal lunate.

In very late enfermead or failed surgery, the radiolunate articulation is compromised, in which case a salvage procedure is required. Fractures of the lunate subchondral bone plate produce irregularity of the lunate articular surface. As emphasized above with SLAC wrist disease, there is progression from dynamic, to static, and then fixed deformity. Lunate collapse, fixed scaphoid rotation. A A composite image of subarticular venous plexus and 3D micro-CT of the subchondral bone plate.

With the coronal lunate fracture, the capitate migrates proximally between the volar and dorsal fragments of the lunate. The factors associated with AVN are different depending upon the patients’ age, sex, race, comorbidities, and are also anatomically specific.

Kienbock’s Disease

A negative ulnar variance leads to increase the loading of the radiocarpal joint—thereby distributing more stress to the lunate than would otherwise occur in an ulnar-neutral wrist. The secondary effect of the lunate collapse is proximal migration of the capitate between the volar and dorsal fragments, producing collapse of the entire central column.
