Rapid and effective reduction is difficult for minimally invasive plate osteosynthesis (MIPO) surgery. This study aims to introduce a bidirectional rapid reductor (BRR) designed to assist in the reduction during MIPO surgery for proximal humeral fractures (PHFs). This retrospective study was conducted between June 2021 and February 2022 in the Third Hospital of Hebei Medical University, involving patients diagnosed with PHFs. A detailed technical approach of BRR in MIPO surgery was described, and the patients' outcomes based on postoperative radiographic results including x-ray postoperative follow-up, and clinical outcome parameters including visual analogue scale (VAS) and constant-Murley score at last follow-up were reported. A total of 12 patients were included in this study, comprising three males and nine females, with an average age of 67.58 years. The mean operative time was 70.92 min (range 63-80 min). The mean blood loss was 102.27 mL (range 50-300 mL). The mean VAS and constant-Murley scores at final follow-up were 0.33 and 88, respectively. All patients had their fractures healed without secondary displacement at last follow-up. One patient experienced shoulder stiffness post-operation. There were no adverse events or complications following the use of this technique, such as acromion fracture, nerve or blood vessel injury. The BRR can assist MIPO for good reduction of PHFs. However, the efficacy should be validated with a large-sample randomized controlled trial and longer follow-up.
