Bidirectional Rapid Reductor in Minimally Invasive Treatment of Proximal Humeral Fractures: A Case Series

Abstract

Abstract Purpose The minimally invasive treatment of proximal humeral fractures (PHFs) represents one of the most challenging problems in orthopedic surgery. This study aims to describe a percutaneous surgery approach involving an originally designed traction device to enhance the closed reduction for PHFs. Furthermore, the clinical outcomes of this minimally invasive technique are assessed. Methods This prospective study was conducted between October 2019 and September 2020 at the Third Hospital of Hebei Medical University, involving patients diagnosed with proximal humeral fracture. The primary outcomes assessed at the one-year follow-up included: (1) the neck-shaft angle and (2) the Constant-Murley scores. Results A total of 12 patients were included in this study, comprising 3 males and 9 females, with an average age of 67.58 ± 10.76 years. All patients had their fractures healed without secondary displacement at the one-year follow-up. There were no instrument-related complications during operation. Postoperatively, superficial infection was found in one patient and donor-site morbidity was found in another patient. Upon final evaluation, the observed neck-shaft angle was with an average of 136.66 ± 7.83° (range from 124.8 to 149.8); all patients’ neck-shaft angle were normal. The Constant-Murley score was categorized as excellent in 7 patients (58.3%) and good in 5 patients (41.7%). Conclusion The bidirectional rapid reductor device shows promising effects in enhancing the efficacy of minimally invasive treatment of PHFs.
