Limited reference is available regarding surgical management in symptomatic ulnar styloid fractures with small bony avulsion. The study goal is to report the surgical outcomes using anchor suture fixation with comparison to traditional tension band wire fixation. We retrospectively reviewed the medical records in patients who underwent surgical repair for unilateral ulnar styloid fractures with distal radioulnar instability between 2004 and 2017. A total of 31 patients were enrolled including two kinds of fixation methods. Anchor suture fixation plus distal radioulnar joint pinning was performed in ten patients with tiny avulsion bony fragments (group A); tension band wire fixation was performed in 21 patients with big styloid fracture fragments (group B). Patient characteristics and 2-year treatment outcomes were compared between two groups based on Mayo Modified Wrist Score (MMWS); Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH); visual analog scale (VAS), and surgical complication. Descriptive statistics were used for calculation of key variables; a p value of < 0.05 was considered statistically significant. Based on Gaulke classification, there were five subtypes in group A and three subtypes in group B. Incidence of concomitant distal radius fractures was significantly higher in group B; other patient characteristics including age, sex, injury side, and time to surgery showed no significant difference. Outcome assessment regarding MMWS, QuickDASH, and VAS was comparable between two groups. Bone-related complications including nonunion, DRUJ subluxation, and styloid resorption were analyzed; the difference was not significant. Incidence of implant-related complications including migration and secondary removal surgery was significantly higher in group B (p = 0.021). Surgical fixation in symptomatic ulnar styloid fractures yields comparable treatment outcomes in both fracture patterns. Implant-related complication with secondary removal surgery is more common in tension band wire group. Anchor suture fixation is a feasible option for tiny styloid avulsion fragments with limited surgical complication.

尺骨茎突骨折的外科治疗：锚钉缝合线和张力带钢丝固定的比较。

关于有症状的尺骨茎突小骨撕脱性骨折的手术治疗方法的参考文献很少。研究目标是与传统的张力带钢丝固定术相比，报告使用锚式缝合固定术的手术效果。我们回顾性分析了2004年至2017年间单侧尺骨茎突骨折并伴有尺骨远端尺骨不稳的患者接受手术修复的病历。共纳入31例患者，其中包括两种固定方法。十名具有微小撕脱性骨碎裂的患者（A组）进行了锚线缝合固定和distal尺远端联合钉扎；张力带线固定术治疗了21例茎突大的骨折碎片（B组）。根据梅奥改良手腕评分（MMWS）比较两组患者的特征和2年治疗结果；手臂，肩膀和手的快速残疾（QuickDASH）；视觉模拟量表（VAS）和手术并发症。描述性统计用于计算关键变量；ap值<0.05被认为具有统计学意义。根据高卢克分类法，A组有5种亚型，B组有3种亚型。B组伴发distal骨远端骨折的发生率显着高于B组。其他患者特征，包括年龄，性别，受伤侧和手术时间均无显着差异。两组之间关于MMWS，QuickDASH和VAS的结果评估相当。骨相关并发症，包括骨不连，DRUJ半脱位，并分析茎突吸收；差异不明显。B组中与移植相关的并发症（包括迁移和二次切除手术）的发生率显着更高（p = 0.021）。有症状的尺骨茎突骨折的手术固定在两种骨折方式中均产生可比的治疗效果。张力带丝组更常见植入相关并发症并进行二次切除手术。对于手术并发症有限的微小茎突撕脱碎片，锚线缝合是可行的选择。有症状的尺骨茎突骨折的手术固定在两种骨折方式中均产生可比的治疗效果。张力带丝组更常见植入相关并发症并进行二次切除手术。对于手术并发症有限的微小茎突撕脱碎片，锚线缝合是可行的选择。有症状的尺骨茎突骨折的手术固定在两种骨折方式中均产生可比的治疗效果。张力带丝组更常见植入相关并发症并进行二次切除手术。对于手术并发症有限的微小茎突撕脱碎片，锚线缝合是可行的选择。
