The role of arthrodesis of the wrist in spastic disorders

We investigated the functional and radiographic outcome of wrist arthrodesis in 11 adults with spastic wrist deformities, carried out by one surgeon between 2003 and 2012. The underlying cause of spasticity was a cerebrovascular insult in five, traumatic brain injury in four, and cerebral palsy in two patients. A dorsal plate and local bone graft was used in all patients. The mean radiographic flexion deformity significantly improved from 67° pre-operatively to 4° of dorsal angulation post-operatively. Thumb-in-palm deformity was more pronounced in three patients after the operation. The functional House score improved in all patients an average of two levels (range 1–3). Level of evidence: IV (Case series).
