Abstract：Objective To investigate the clinical effect of reconstructing irreducible comminuted radial head fracture with autogenous iliac bone graft. Methods A total of 27 patients with Mason type Ⅲ and type Ⅳ comminuted radial head fracture admitted to the Fourth Affiliated Hospital of Kunming Medical University from June 2016 to June 2019 were selected as the research subjects. The comminuted radial head fractures were all surgically reconstructed with autogenous iliac bone. All patients were followed up for more than 12 months. Heal, Broberg-Morrey elbow fracture outcome score, and disability of arm, shoulder and hand scale (DASH) score were recorded at the last follow-up. The range of motion of the elbow of the affected side and the healthy side was compared in the same patient at the last follow-up. Results At the last follow-up, X-ray graphs showed that 25 patients had bony healing of the radial head. The bony healing rate was 92.6%, and the mean healing time was (11.35±1.15) weeks. At the last follow-up, the excellent and good rate of Broberg-Morrey elbow fracture outcome score was 88.9%, and the average DASH scale score was (15.52±4.39) points. At the last follow-up, the flexion and extension, pronation and supination range of motion of the elbow of the affected side was lower than that of the healthy side, and the differences were statistically significant (all P ＜ 0.05). Conclusion Reconstruction of irreducible comminuted radial head fractures with autogenous iliac bone graft can achieve satisfactory results in the short and medium term, but the long-term results need to be further studied.
