UNASSIGNED: @entity1897 is a rare but important complication of @entity572 ( @entity572 ) and has previously been reported in the ipsilateral arm and associated with @entity625 . The results of 7004 primary hip arthroplasties performed between January 1993 and February 2009 were retrospectively reviewed to identify @entity1 who reported @entity16 , with ten @entity1 identified at mean follow-up of 57 months (range   =   3-195 months). Eight @entity1 experienced unilateral ulnar nerve symptoms in the contralateral upper limb post-surgery, one @entity1 experienced symptoms in the ipsilateral upper limb and one @entity1 experienced symptoms in both upper limbs. The incidence of @entity16 was 0.14%. All @entity1 had a pre-operative diagnosis of @entity571 and none had @entity6 , a previous history of @entity16 or @entity625 . All operations were primary arthroplasties and were performed under the care of a single surgeon in a single centre. Two of the ten @entity1 (20%) had a general anaesthetic. The pattern of symptoms reported, i.e. mainly unilateral affecting the contralateral side with variable resolution, contrasts with previous studies and suggests that intraoperative @entity1 positioning may be an important factor influencing @entity16 following @entity572 . Attention to support and positioning of the contralateral arm may help reduce the incidence of this complication.
