Treatment of pathological XXXX of the humerus with a locked intramedullary nail.

@entity174 @entity1 @entity3
OBJECTIVE: The humerus is a common site for @entity3 . Intramedullary nail fixation has been reported to be the best form of fixation for this disease but complications occur. This study aimed to assess the use of a new humeral nail to treat pathological @entity174 and impending pathological @entity174 of the humerus. METHODS: 29 @entity1 received 31 Austofix locked intramedullary humeral nails: 25 for pathological @entity174 and 6 for impending @entity174 ; 24 nails were inserted anterograde and 7 retrograde. Cement augmentation was applied in 4 @entity1 , and adjuvant therapy was used in 28 @entity1 . Complications occurred in 12 @entity1 . RESULTS: Fixation failed in 6 @entity1 : 2 due to intraoperative @entity174 during retrograde nailing, one due to a @entity174 through screw holes postoperatively, and 3 due to local progression of disease. Difficulty in distal locking of the nail was encountered in 4 @entity1 . Locked intramedullary nailing resulted in a stable humerus in 80% of @entity1 . CONCLUSION: Retrograde insertion of the nail is associated with an increased risk of intra-operative @entity174 , and disease progression can occur, despite the administration of adjuvant therapy.
