Abstract:
Objective: To explore the feasibility and clinical effects of Double-Pulley technique combined with 8-shaped tension band in teatment of comminuted fractures of distal patellar pole. Methods: From Jan. 2017 to Apr. 2018, 10 patients (6 males and 4 females) were treated with Double-Pulley technique combined with 8-shaped tension band in our hospital. The ages of patients ranged from 28 to 58 years old, with an average of (36.4± 11.4) years old. The average time from injury to surgery was (2.8 ± 1.1) d, ranging from 1 to 5 d. The injury cause was traffic accident in 6 cases, falling iniury in 3 cases, and sport injury in 1 case. Bostman's patellar fracture function evaluation system was used to evaluate the postoperative knee joint function. The clinical evaluation indexes included the excellent and good rate of Bostman's patellar fracture function score, and X-ray examination results and knee mobility during follow-up. Results: All patients were followed up for 16 to 24 months. The incision of all patients healed well, and no anterior knee pain or complications were found. Six months after surgery, X-ray examination showed that the patellar fracture healing of 10 patients were all osteonal union. Six months after surgery, the flexion range of knee joint was 132.0°±12.3°, and Bostman's patellar fracture function score was 28.5±1.8, with the excellent and good rate being 100% (excellent in 9 cases and good in 1 case). Conclusion: Double-Pulley technique combined with 8-shaped tension band is effective and reliable in the treatment of comminuted fractures of distal patellar pole, and the patients can start functional exercise early after surgery.
