UPPER EXTREMITY FUNCTION AFTER WRIST ARTHRODESIS

Several studies have examined the normal range of wrist motion used to accomplish activities of daily living. Little information is present, however, on what functional limitations might be experienced by patients actually undergoing formal wrist arthrodesis. This study undertook comprehensive functional evaluation of 23 patients who underwent wrist arthrodesis for post-traumatic conditions. Follow-up evaluation averaged 54 months and consisted of a clinical questionnaire, the Jebsen Hand Function Test, and a functional rating devised by Buck-Gramcko/Lohmann. Fifteen of the 23 patients returned to their original jobs, and all patients noted that although the vast majority of tasks could still be performed, these tasks were undertaken in a modified fashion. The most difficult daily tasks for patients with a wrist arthrodesis to perform involved perineal care and manipulating the hand in tight spaces. The Jebsen Hand Function Test demonstrated a 64% task completion rate with the fused wrist compared to a 78% task completion rate for the normal wrist. The Buck-Gramcko/Lohmann evaluations demonstrated an average score of 8.3 out of a possible 10. Patients who have undergone wrist arthrodesis can accomplish most activities of daily living and other functional requirements, although some adaptation to accomplish these tasks is required.
