Abstract:
Objective:To investigate the efficacy of fixation with cannulated screws alone via the Kocher approach in the treatment of adult humeral capitulum fractures.Methods:From August 2016 to August 2020, 16 patients with humeral capitulum fracture were treated at Department of Upper Limb Orthopedics, Zhengzhou Orthopaedic Hospital. They were 10 males and 6 females, aged from 36 to 62 years (average, 45 years). The left side was affected in 10 cases and the right side in 6. According to the Ring classification, 3 cases were type Ⅰ, 3 cases type Ⅱ, 6 cases type Ⅲ, and 4 cases type Ⅳ. All patients were treated with the Kocher approach on the lateral side of the elbow. After reduction under direct vision, the fractures were fixated temporarily with Kirschner wires and finally with cannulated screws. On the second postoperative day, the patients started active flexion and extension of the elbow joint and took indomethacin orally to prevent heterotopic ossification. At the last follow-up, the curative efficacy was evaluated according to the Mayo elbow performance score (MEPS). The flexion and extension of the elbow joint and the rotation of the forearm were also recorded.Results:All patients were followed up for 10 to 19 months (mean, 14.3 months) after surgery. Bony union was achieved after 7 to 12 monthes (average, 11.3 monthes) in all the 16 patients, 2 of whom developed heterotopic ossification. By the MEPS evaluation at the last follow-up, 8 cases were excellent, 6 good and 2 fair, scoring an average of 89.5 points (from 73 to 95 points). At the last follow-up, the elbow flexion ranged from 80° to 130° (averaging 113°), extension from 5° to 30° (averaging 15°), forearm pronation from 62° to 75° (averaging 67°), and forearm supination from 50° to 90° (averaging 75°).Conclusion:When the fracture ends are exposed through the lateral Kocher approach, the fracture fragments fixated with cannulated screws only, and the patients encouraged to start elbow joint exercises in the early stage, the treatment of adult humeral capitulum fractures can result in satisfactory curative effects.
