Abstract：
OBJECTIVE: This study investigated the effectiveness of volar plate surgery in patients with distal radius fractures (DRFs) initially treated nonsurgically but later experiencing reduction loss during follow-ups. Specifically, it assessed the impact of early surgery (E) (<3 weeks) versus delayed surgery (D) (3-6 weeks) on wrist function in surgically treated DRFs.
METHODS: This retrospective study included 131 patients who underwent surgery after loss of reduction. Among them, 42 patients had delayed surgery, whereas 89 received early surgical treatment. The mean follow-up duration was 18 months. The primary outcome measure was Disabilities of the Arm, Shoulder, and Hand scores. Secondary outcomes included Short Form-12 physical component summary and mental component summary scores, postoperative range of motion, and radiological measurements such as radial length, radial inclination angle, and volar tilt angle. Fracture types were categorized using Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association classification based on radiological images.
RESULTS: All 131 DRFs achieved radiological union. Mean Disabilities of the Arm, Shoulder, and Hand scores were 8.0 (range, 0-78) and 10.8 (range, 0-73) for groups E and D, respectively, and the difference was not considered clinically relevant. Short Form-12 physical component summary scores (49.4 for E; 45.3 for D) and Short Form-12 mental component summary scores (52.3 for E; 53.5 for D) were similar in the two groups. Radiological measurements and range of motion were similar in the two groups. Complications, including carpal tunnel syndrome, superficial radial nerve neuropraxia, and complex regional pain syndrome, occurred in 12 (13.5%) E group patients and 9 (21.4%) D group patients.
CONCLUSIONS: Clinical and radiological results of early and delayed surgery after loss of reduction in secondary displaced DRF were similar. However, complication rates were higher in delayed surgery.
METHODS: Prognostic IV.

摘要：
目的：本研究调查了掌侧钢板手术对桡骨远端骨折（DRF）患者的有效性，这些患者最初非手术治疗，但后来在随访期间出现复位丢失。具体来说,它评估了早期手术（E）（<3周）与延迟手术（D）（3-6周）对手术治疗的DRF腕关节功能的影响。
方法：这项回顾性研究纳入了131例患者，这些患者在复位丢失后接受了手术。其中,42名患者延迟手术，而89人接受早期手术治疗。平均随访时间为18个月。主要结果指标是手臂残疾，肩膀,和手得分。次要结果包括ShortForm-12身体成分总结和心理成分总结得分，术后活动范围，和放射学测量，如径向长度，径向倾角,和掌侧倾斜角度。根据放射学图像，使用Arbeitsgemedinschaftfür骨合成/骨科创伤协会分类对骨折类型进行分类。
结果：所有131个DRF均实现放射学联合。手臂的平均残疾，肩膀,手得分为8.0(范围，0-78）和10.8（范围，0-73）对于E组和D组，分别,差异被认为没有临床意义.两组的简短形式12的身体成分摘要得分（E为49.4；D为45.3）和简短形式12的心理成分摘要得分（E为52.3；D为53.5）相似。两组的放射学测量和运动范围相似。并发症,包括腕管综合症,桡神经浅区神经错用,和复杂的区域疼痛综合征，发生在12例(13.5%)E组患者和9例(21.4%)D组患者中。
结论：继发移位DRF减少后早期和延迟手术的临床和放射学结果相似。然而,延迟手术的并发症发生率较高.
方法：预后IV.
