Objective To investigate the effectiveness of sharp teeth hook plate by cutting for the treatment of olecranon fractures by comparison with Kirschner wire tension belt and locking plate. Methods Between January 2011 and April 2015, 32 cases of olecranon fractures were treated. Fracture was fixed with sharp teeth hook plate by cutting in 12 cases (trial group) and with Kirschner wire tension belt or locking plate in 20 cases (control group). There was no significant difference in gender, age, side and type of fracture, and time from injury to operation between 2 groups (P > 0.05). The healing time of fractures and complications were recorded. At 1 year after operation, the subjective function results were evaluated according to Disability of Arm, Shoulder, and Hand (DASH) score, and objective function results by Mayo Elbow Score (MEPS); visual analogue scale (VAS) was used for elbow joint pain, and range of motion of flexion and extension of elbow joint was measured. Results All incisions healed by first intention, with no vascular and nerve injuries. All patients were followed up 12-36 months with an average of 18 months. All fractures healed, and there was no significant difference in the healing time between 2 groups (P > 0.05). Loosening of Kirschner wire occurred in 2 cases of control group, but no loosening of internal fixation was observed in trial group after operation. There was no significant difference in the incidence of complications between 2 groups (P > 0.05). The DASH, MEPS, VAS score, and range of motion of flexion in trial group were superior to those in control group, showing significant differences (P < 0.05) at 1 year after operation. There was no significant difference in range of motion of extension between 2 groups (P > 0.05). Conclusion Sharp teeth hook plate for treatment of olecranon fractures overcomes the shortcomings that Kirschner wire tension is easy to slide and locking plate has a compression effect on triceps tendon, so it has good effectiveness.
