Sled board internal fixation for olecranon fractures / 中华创伤骨科杂志

ABSTRACT

Objective:To investigate the therapeutic effects of sled board internal fixation on the treatment of olecranon fractures.Methods:The clinical data were retrospectively analyzed of the 21 patients with olecranon fracture who had been treated with sled board internal fixation at Department of Traumatology and Orthopedics, Beijing Jishuitan Hospital from May 2019 to January 2021. They were 11 males and 10 females with 14 left and 7 right sides affected, aged from 18 to 68 years (mean, 42.0 years). By the preoperative Mayo classification for olecranon fractures, one case was type ⅠA, 11 cases were type ⅡA and 9 cases type ⅡB; by the Schatzker classification, one case was type A, 4 cases were type B and 16 cases type C. The operation time and the complications were recorded; at the last follow-up, the range of motion of the elbow joint was recorded and the elbow function and pain were evaluated by the Mayo elbow performance score (MEPS) and visual analogue scale (VAS).Results:The 21 patients were followed up for 13 to 34 months (mean, 19.6 months) after operation. At the last follow-up, the flexion and extension of the affected elbow averaged 139.8° (from 125° to 160°), and the pronation-supination 177.9° (from 160° to 180°). The operation time averaged 77.8 min (from 40 to 135 min). Postoperative olecranon skin discomfort developed in 4 patients, 2 of whom underwent removal of internal fixation; no such complication as internal fixation breakage, screw loosening, incision infection or elbow stiffness was observed in the other 17 cases. At the last follow-up, the MEPS scores averaged 97.9 points (from 85 to 100 points) and the VAS scores 0.2 points (from 0 to 2 points).Conclusion:The sled board internal fixation can result in good therapeutic effects on the treatment of olecranon fractures.
