Objective To observe the efficacy of anteromedial approach of elbow joint in treating O′Driscoll type Ⅱ and Ⅲ fractures of coronoid process of ulna.
Methods A total of 100 patients with O′Driscoll type Ⅱ and Ⅲ fractures of coronoid process of ulna were selected as research objects, and they were divided into control group and study group according to the order of hospital admission, with 50 cases in each group. The control group was treated with a lateral approach, while the study group was treated with an anteromedial approach of elbow joint. The efficacy, mobility of elbow joint and incidence of complications were compared between the two groups.
Results The excellent rate of the study group was 90.00%, which was significantly higher than 74.00% of the control group (P < 0.05); at 1 month, 3 and 6 months after surgery, the flexion and extension mobility of elbow joint in the study group was (88.69±11.32)°, (111.14±14.02)° and (121.21±15.34)° respectively, which was significantly higher than (76.16±11.57)°, (98.33±12.27)° and (110.38±13.80)° in the control group (P < 0.05); the rotation mobility of elbow joint in the study group was (91.29± 10.16)°, (111.29±16.28)° and (121.47±16.39)° respectively, which was significantly higher than (79.85±10.69)°, (100.61±13.30)° and (113.46±12.62)° in the control group (P < 0.05); the postoperative incidence rate of complications in the study group was 10.00%, which was significantly lower than 28.00% in the control group (P < 0.05).
Conclusion Anteromedial approach of elbow joint is effective in treating patients with O′Driscoll type Ⅱ and Ⅲ fractures of coronoid process of ulna, which is beneficial for the recovery of elbow joint function, and has higher safety.
