The objective of this study was to investigate and compare the clinical outcomes of combined medial and lateral approach with the paratricipital approach in open reduction and internal fixation of type C distal humerus fractures.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>From May 2018 to April 2020, 37 patients with type C distal humerus fracture who accepted open reduction and internal fixation in our hospital were enrolled in this study. All cases were randomly divided into two groups according to the surgical approach: combined medial and lateral approach group (19 cases), paratricipital approach group (18 cases). All of the patients received open reduction and double vertical plates fixation. The operation and follow\u2010up indexes, including operation time, blood loss, incision length, triceps muscle strength, flexion\u2010extension arc of elbow and forearm rotation arc, were recorded and compared. Caja score was used to assess the quality of fractures reduction. Mayo Elbow Performance Score (MEPS) was used to evaluate the elbow function in the follow\u2010up. Complications such as incision infection, ulnar nerve injury, degenerative osteoarthritis, and heterotopic ossification were analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The differences in age, gender, and AO classification of fractures between two groups were not statistically significant (<jats:italic>p<\/jats:italic>\u2009&gt;\u20090.05). The sum of medial and lateral incision length of combined approach group was longer than the midline incision of paratricipital approach group (15.4\u2009\u00b1\u20090.8 vs. 14.6\u2009\u00b1\u20090.8, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05), but there was no significant difference in operation time (103.5\u2009\u00b1\u200910.2 vs. 106.0\u2009\u00b1\u20098.8, <jats:italic>p<\/jats:italic>\u2009&gt;\u20090.05), blood loss (71.3\u2009\u00b1\u200924.5 vs. 72.8\u2009\u00b1\u200924.6, <jats:italic>p<\/jats:italic>\u2009&gt;\u20090.05), and Caja score (16.05\u2009\u00b1\u20095.67 vs. 15.56\u2009\u00b1\u20095.66, <jats:italic>p<\/jats:italic>\u2009&gt;\u20090.05). During the follow\u2010up, the MEPS of combined approach group was higher than that of paratricipital approach group at 3\u2009months postoperatively (80.5\u2009\u00b1\u20095.7 vs. 68.9\u2009\u00b1\u20098.1, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05), but there was no significant difference in MEPS at 6\u2009months postoperatively (83.9\u2009\u00b1\u20096.6 vs. 79.7\u2009\u00b1\u20097.0, <jats:italic>p<\/jats:italic>\u2009&gt;\u20090.05) and at the last follow\u2010up (86.8\u2009\u00b1\u20097.1 vs. 86.9\u2009\u00b1\u20097.7, <jats:italic>p<\/jats:italic>\u2009&gt;\u20090.05) between the two groups. There was no significant difference in triceps muscle strength (<jats:italic>p<\/jats:italic>\u2009&gt;\u20090.05), flexion\u2010extension arc (126.8\u2009\u00b1\u20095.3 vs. 128.9\u2009\u00b1\u20096.0, <jats:italic>p<\/jats:italic>\u2009&gt;\u20090.05), and forearm rotation arc (163.2\u2009\u00b1\u20095.3 vs. 163.6\u2009\u00b1\u20094.8, <jats:italic>p<\/jats:italic>\u2009&gt;\u20090.05) at the last follow\u2010up.
