Management of Distal Ulna Fractures by Distal Ulnar Hook Plate

Objective: To determine the efficacy and analyze the results of Locking Compression Distal Ulna Hook Plate (LC-DUP) in patients suffering distal ulnar fracture (either isolated or associated with distal radius fractures). Patients and methods: This prospective clinical trial study included 18 patients, the age of the studied group was ranged from 22 to 58 years; half of the group had age ranged from 30 to 40 years with distal ulna fractures treated by Locked compression distal ulnar hook plates during the period from November 2019 to July 2020. Results: All patients eventually achieve full union. Only two of them had delayed union. The radiological and clinical assessment of fracture site and DRUJ was promising. More than three quarters of patients had excellent outcome, while the rest half of them had good, and the other half had satisfactory outcome according to the Modified MAYO Score which had mean of (90.5 ± 14.6).where the mean of the Quick DASH score was (9.8 ± 5.8). Conclusion: The good outcomes achieved in this study suggest that use of the distal ulna hook plate could be an alternative treatment method for intra articular ulna neck or head fractures, as well as basal oblique ulnar styloid fractures.
