To study the outcome of surgical treatments for anterolateral (AL) fracture of the ulna coronoid process (Adams Type IV) and summarize the characteristics of this type of fracture and to guide clinical applications.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>From February 2015 to April 2021, 32 patients were included in the study. All patients had standard radiography with anteroposterior and lateral views, computed tomography, and intraoperative fluoroscopy. All patients were treated surgically. Surgery\u2010related information, including surgical approach, operation duration, blood loss, and repairing the lateral collateral ligament and the medial collateral ligament integrity, were recorded. The patient's clinical details, such as the final range of motion (ROM), the Broberg\u2013Morrey scores and the visual analogue scale (VAS) at the last follow\u2010up, were described. The chi\u2010square test or Fisher's exact test was used for statistical analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We divided patients into two groups according to the anterolateral coronoid fracture morphology. In the intact group, 20 patients with an intact anterolateral coronoid fracture fragment. In the comminuted group, 12 patients with comminuted anterolateral coronoid fracture fragments extended the less sigmoid notch of the ulna. There was no difference in age, sex, total incision length, follow\u2010up duration, and recovery with rehabilitation among the two groups (all <jats:italic>P<\/jats:italic>s &gt;0.05). The other follow\u2010up outcomes, such as elbow ROM (Flexion, Extension, Posterior rotation, Anterior rotation), VAS score, or Broberg\u2013Morrey scores, were not different between the two groups (all <jats:italic>P<\/jats:italic>s &gt;0.05). Both groups achieved relatively satisfactory clinical outcomes, and the Broberg\u2013Morrey score and index excellence rate reached 84.38%. There is a statistical difference in the history of elbow dislocation (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.017), radial head fracture type (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.041), operation duration (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.014) and blood loss at operation (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.029) between the two groups. Cannulated screws, anchors, and sutures were used as point fixation in the coronoid process of the ulna.
