Background: A distal ulnar fracture that occurs alone is a rare injury. It frequently results from a direct
trauma to the ulnar border, which already has inadequate soft tissue. The purpose of this study was to
assess the clinical & radiological outcomes of using a flexible intramedullary nail to treat displaced distal
ulna fractures in adults. Methods: Prospective research included 20 adults with displaced distal ulna
fractures admitted in orthopedic department of Sohag University Hospital. Evaluation was done using
Grace & Eversmann rating system, VAS score & DASH score (Disabilities of the Arm, Shoulder, &
Hand). Results: Regarding the surgical outcomes; the operation time ranged from 52 to 127 min with a
mean time of 86.9 ± 16.8 mins. The time of consolidation ranged from 9 to 27 weeks with a mean of 16 ±
4.05 weeks. Regarding the complication, 5 (25%) patients had superficial infection, and 2 (10%) patients
had a nail back-out. Most patients experienced significant improvement in the Grace & Eversmann rating
system, with excellent outcomes observed at 6 months postoperatively. Conclusion: The use of flexible
intramedullary nails for fixation of displaced distal ulna fractures in adults yielded favorable clinical &
radiological outcomes. Keywords: Fixation, Distal Ulna, Ulna Fractures, Flexible Intramedullary Nail
