Abstract:
Objective:To investigate the clinical efficacy of the bone-forming channel technique combined with double plates in the treatment of postoperative aseptic nonunion of the humeral shaft. Methods:A retrospective study was conducted to analyze the data of 39 patients with postoperative aseptic nonunion of the humeral shaft who had been treated by bone-forming channel technique combined with double plates from March 2018 to December 2022. There were 20 males and 19 females, with an age of (46.5±1.6) years. The bone nonunion was atrophic in 18 cases and hypertrophic in 21 cases. The operation time, intraoperative bleeding, fracture healing time and complications were recorded. The shoulder and elbow functions were evaluated before operation and at the final follow-up using the Disabilities of the Arm, Shoulder and Hand (DASH) score, Neer's shoulder function score, and Mayo's elbow performance score (MEPS). Results:All the 39 patients were followed up for an average duration of (13.8±3.5) months. The operation time was (84.3±7.3) minutes, the intraoperative bleeding (127.5±4.5) mL, the fracture healing time (24.4±1.3) weeks, and the fracture healing rate 100% (39/39). None of the patients had such postoperative complications as infection, neurovascular injury, or re-rupture of internal fixation. At the final follow-up, the patients' DASH score [(7.4±1.2) points], Neer's shoulder function score [(93.4±5.2) points], and MEPS [(94.6±3.3) points] were significantly improved compared respectively with the preoperative values [(26.6±8.4) points, (74.3±6.5) points, and (73.8±5.3) points] ( P<0.05). At the final follow-up, the patients' forward flexion and upward mobility was 168.5°±3.4°, abduction and upward mobility was 167.5°±5.2°, and horizontal forward flexion was 129.5°±11.8°. Conclusion:In the treatment of postoperative aseptic nonunion of the humeral shaft, since the bone-forming channel technique combined with double plates can achieve satisfactory clinical outcomes, it is worthy of clinical application.
