Presentation

Patient presents for routine follow up for her four-corner fusion. It was originally placed for advanced SLAC wrist.

Patient Data

Age: 52Y
Gender: Female

Four-corner fusion (intercarpal arthrodesis of the capitate, lunate, triquetrum, and hamate) of right wrist with autologous bone graft (scaphoid).

Advanced SLAC wrist (scapholunate advanced collapse)

  • widening of the scapholunate interval
  • proximal migration of the capitate
  • advanced degenerative changes in the wrist
  • wrist instability on physical exam

Case Discussion

This patient originally presented with advanced right wrist arthritis, most likely secondary to chronic rupture of the scapholunate ligament (from SLAC wrist).

She chose a limited wrist fusion using a four-corner fusion, as opposed to a total wrist fusion.
