In this study, it was aimed to evaluate the short-term results of open reduction internal fixation (ORIF) and autograft + ORIF approaches in the treatment of isolated distal ulna fractures. Hypothesis: Using autograft in the surgical treatment of isolated distal ulna fractures with open reduction internal fixation improves short-term clinical outcomes. Patients and methods: The records of isolated distal ulna fractures (distal one-third) operated at the Mal-tepe University Hospital Orthopedics and Traumatology Clinic between January 2009 and December 2019 were retrospectively reviewed. The cases were divided into two groups according to surgical approach, ORIF (n = 40) or autograft + ORIF (n = 34). Results: The mean age was 41.55 +/- 12.42 years. 52.7% of the cases were female, 67.6% of the fractures were right-sided, and 37.8% of the traumas causing the fracture were high-energy trauma. There was no significant difference between the ORIF and autograft + ORIF groups in terms of age, gender, side and severity of trauma (p > 0.05). It was found that pseudoarthrosis development was significantly more prevalent in the ORIF group (25%) compared to the autograft + ORIF group (5.9%) (p = 0.026). The median (1st quartile-3rd quartile) time to union was 16 (14-17) weeks in the ORIF group, and 9.5 (8.5-12) weeks in the autograft + ORIF group. Compared to ORIF, the time to union was significantly shorter with the autograft + ORIF procedure (p < 0.001). At both the 3rd and 12th month follow-up examinations, the autograft + ORIF group was found to have significantly higher MAYO score and grip strength, and lower DASH score, compared to the ORIF group. Discussion: When an autograft is used in addition to ORIF in the surgical treatment of isolated distal ulna fractures, the bone heals faster, pseudoarthrosis develops less frequently, and short-term (3rd and 12th months) functional results are better.
