To present our experience on intramedullary nailing device Sonoma Wrx (Sonoma Orthopedic Products Inc., Santa Rosa, CA, USA) used for internal fixation of extra-articular or simple intra-articular distal radius fractures in adult population.
This study was conducted from February 2011 to October 2016. A total of 48 patients (mean age 47.3±5.6 years, 35.4% females) with distal radius fracture, who underwent intramedullary distal radius fixation by using Sonoma Wrx were included in this retrospective study. Clinical outcome measures (range of motion [ROM], visual analog scale [VAS]), functional outcomes (Disabilities of the Arm, Shoulder and Hand [DASH] score and Gartland-Werley score), radiographic scores (Stewart score) and parameters (radial inclination, volar tilt, radial height, radio-ulnar variance) and complications were evaluated.
The total surgery time was 24.3±2.3 minutes. Patients were followed up for 24.7±3.4 weeks. Complete fracture union was obtained at 5.5±0.9 weeks. The postoperative low VAS pain score (1.6±0.93) and high ROM values (76.7° for extension, 78.5° for supination, 80.1° for flexion, and 82.3° for pronation) indicated a very good clinical outcome. DASH score of 8.3±1.5 and Gartland-Werley score of 2.8±4.1 showed good functional outcome. The radiographic Stewart score was 1.0±1.2. Radial inclination, volar tilt, and radial height significantly increased (p<0.001), and radio-ulnar variance decreased (p=0.001) with surgery. No postoperative complication was recorded in 40 patients (83.3%).
Sonoma Wrx, which is an expansible intramedullary elastic locking distal radius nail, offers a good alternative technique for internal fixation of unstable distal radius fractures with the advantage of minimum soft-tissue dissection and related postoperative complications.
介绍我们使用索诺玛Wrx髓内钉装置（美国加利福尼亚州圣罗莎市索诺玛骨科产品公司）对成年患者关节外或简单关节内桡骨远端骨折进行内固定的经验。
本研究于2011年2月至2016年10月进行。本回顾性研究纳入了48例桡骨远端骨折患者（平均年龄47.3±5.6岁，女性占35.4%），这些患者采用索诺玛Wrx进行了桡骨远端髓内固定。评估了临床结局指标（活动范围[ROM]、视觉模拟评分[VAS]）、功能结局（手臂、肩部和手部功能障碍[DASH]评分和加特兰 - 韦利评分）、影像学评分（斯图尔特评分）和参数（桡骨倾斜度、掌倾角、桡骨高度、桡尺骨差异）以及并发症。
总手术时间为24.3±2.3分钟。患者随访24.7±3.4周。在5.5±0.9周时实现了骨折完全愈合。术后低VAS疼痛评分（1.6±0.93）和高ROM值（伸展76.7°、旋后78.5°、屈曲80.1°、旋前82.3°）表明临床结局非常好。DASH评分为8.3±1.5，加特兰 - 韦利评分为2.8±4.1，显示功能结局良好。影像学斯图尔特评分为1.0±1.2。手术前后桡骨倾斜度、掌倾角和桡骨高度显著增加（p<0.001），桡尺骨差异减小（p = 0.001）。40例患者（83.3%）未记录到术后并发症。
索诺玛Wrx是一种可扩张的髓内弹性锁定桡骨远端钉，为不稳定桡骨远端骨折的内固定提供了一种良好的替代技术，具有软组织剥离最少及相关术后并发症少的优点。
