A small series such as this does not warrant definite conclusions, but it is suggested that the pain associated with an ununited fracture of the carpal navicular is primarily occasioned by the impingement of the radial styloid process against the distal navicular fragment. Excision of the styloid process has given excellent results in ten patients up to the present time; fair results have been obtained in one and poor results in two. The procedure is simple and convalescence is short. If the operation is unsuccessful little has been lost and any of the more radical surgical procedures may be used.
