Idiopathic avascular necrosis of the capitate is a disorder of unknown etiology that causes wrist pain and limitation of function. Many different treatments have been presented in the literature with varying clinical results and levels of patient satisfaction. We present a case of a 23-year-old woman successfully treated with scaphocapitolunate arthrodesis.

Purpose: To determine the effect of simulated radioscapholunate fusion with distal scaphoid excision (RSLF+DSE), 4-corner fusion with scaphoidectomy (4-CF), and proximal row carpectomy (PRC) on the wrist's range of motion (ROM), contact pressure, and contact force in a cadaveric model.
Methods: Ten freshly frozen cadaveric wrists were tested under 4 sequential conditions: native wrist, RSLF+DSE, 4-CF, and PRC. The simulated fusions were performed using two 1.

Avascular necrosis of the capitate is a rare disorder of unknown aetiology that causes wrist pain and limits function. From 2009 to 2017, we performed scaphocapitolunate arthrodesis on five patients (one male, four females) with a mean age of 35 years (range 30-37) who had idiopathic avascular necrosis of the capitate. All patients had scaphocapitate and lunocapitate arthritis confirmed by arthroscopy.

Avascular necrosis of the capitate is rare. Little is known about the aetiology, disease progression or optimal management. From 1992 to 2012 we treated six patients; four had a scaphocapitolunate arthrodesis and two had a four corner arthrodesis.

Longstanding scaphoid nonunion, scaphoid malunion, and chronic scapholunate dissociation result in malalignment of the carpal bones, progressive carpal collapse, instability, and osteoarthritis of the wrist. The most commonly used procedures to treat scaphoid nonunion advanced collapse (SNAC) and scapholunate advanced collapse (SLAC) wrists are the four-corner fusion (4CF) and the proximal row carpectomy (PRC). Here we describe a different treatment option: radial styloidectomy and scaphocapitolunate (SCL) arthrodesis.

The most commonly used procedures to treat scaphoid nonunion advanced collapse (SNAC) and scapholunate advanced collapse (SLAC) wrists are the four-corner fusion (4CF) and the proximal row carpectomy (PRC). The purpose of this study was to evaluate the clinical outcome of a different treatment modality: radial styloidectomy and scaphocapitolunate (SCL) arthrodesis.
