To evaluate the outcomes of "tent form" triangular fibrocartilage complex (TFCC) repair combined with dorsal distal radioulnar joint (DRUJ) capsule imbrication for posttraumatic chronic DRUJ instability.
All patients treated with arthroscopic "tent form" TFCC repair and DRUJ capsule imbrication from 2016 to 2019 were retrospectively reviewed. The inclusion criteria were symptomatic chronic DRUJ instability for >6 months and dorsal DRUJ subluxation on magnetic resonance imaging. The Disabilities of the Arm, Shoulder, and Hand score, Patient-Rated Wrist Evaluation, grip strength, Modified Mayo Wrist Score, range of motion, and distal radioulnar joint stability were assessed for a minimum of 2 years postoperatively.
Thirty-eight patients were included in the final analysis. The average follow-up duration was 35.6 months (range, 24-48 months). The 24-month postoperative grip strengths and 3-dimensional motions of wrist were not significantly different from that of the nonoperated wrist. Compared with their preoperative status, Disabilities of the Arm, Shoulder, and Hand score, Patient-Rated Wrist Evaluation, and Modified Mayo Wrist Score indicated the significant improvement with P values of .001, .001, and .002, respectively.
In chronic DRUJ instability with a loosening dorsal capsule, "tent form" TFCC transcapsular repair combined with DRUJ capsule imbrication restored the integrity of TFCC and dorsal DRUJ capsule and achieved a promising outcome. We recommend this procedure as an option of treatment for patients with posttraumatic chronic DRUJ instability.

评估“帐篷式”三角纤维软骨复合体（TFCC）修复联合背侧远侧桡尺关节（DRUJ）囊缝合并发创伤后慢性 DRUJ 不稳定的疗效。
回顾性分析 2016 年至 2019 年接受关节镜“帐篷式”TFCC 修复和 DRUJ 囊缝合并发创伤后慢性 DRUJ 不稳定的所有患者。纳入标准为症状性慢性 DRUJ 不稳定>6 个月，磁共振成像显示背侧 DRUJ 半脱位。术后至少 2 年评估患者的手臂、肩部和手残疾程度（DASH）评分、患者腕关节评估（PRWE）、握力、改良 Mayo 腕关节评分、活动度和远侧桡尺关节稳定性。
最终纳入 38 例患者进行分析，平均随访时间为 35.6 个月（范围，24-48 个月）。术后 24 个月的握力和手腕 3 维运动与未手术侧无显著差异。与术前相比，DASH 评分、PRWE 和改良 Mayo 腕关节评分均有显著改善（P 值分别为<.001、<.001 和<.002）。
在背侧囊松动的慢性 DRUJ 不稳定中，“帐篷式”TFCC 经囊修复联合 DRUJ 囊缝合并发创伤后慢性 DRUJ 不稳定，恢复了 TFCC 和背侧 DRUJ 囊的完整性，取得了良好的疗效。我们建议将该手术作为治疗创伤后慢性 DRUJ 不稳定患者的一种选择。
