To review the results of our experience with the Medartis Aptus plating system for four corner arthrodesis of the wrist, which uses a combination of compression screws and variable angle locking screws.
We reviewed the results of 17 procedures in 16 patients that underwent scaphoid excision and four corner fusion using the Medartis Aptus system between May 2010 and June 2014. The primary outcome measure was radiographic and clinical union.
The mean clinical follow up time was 20.6 mo. The mean union time was 6 mo. Two non-unions required revision procedures. The mean disabilities of the arm, shoulder and hand score taken after union was 36. The mean final grip strength was 27 kg. The mean final range of movement was 30° flexion and 31° of extension. All patients had a restored scapholunate angle on postoperative radiographs. There were no incidences of dorsal impingement.
Overall our experience with the Aptus plating system shows comparable results to other methods of fixation for four corner fusion, in the short to medium term.
回顾我们使用Medartis Aptus钢板系统进行腕关节四角融合术的经验结果，该系统采用加压螺钉和可变角度锁定螺钉相结合的方式。
我们回顾了2010年5月至2014年6月期间16例患者接受的17例手术结果，这些手术采用Medartis Aptus系统进行舟骨切除和四角融合。主要观察指标为影像学和临床愈合情况。
平均临床随访时间为20.6个月。平均愈合时间为6个月。2例骨不连需要进行翻修手术。愈合后手臂、肩部和手部残疾评分的平均值为36分。最终平均握力为27千克。最终平均活动范围为屈曲30°和伸展31°。所有患者术后X线片显示舟月角恢复正常。无背侧撞击事件发生。
总体而言，我们使用Aptus钢板系统的经验表明，在短期至中期内，其结果与其他四角融合固定方法相当。
