Abstract：
UNASSIGNED: This research sought to analyze a cohort of patients with extensor pollicis longus (EPL) ruptures after volar locked plating of a distal radius fracture (DRF) to characterize the incidence of ruptures that are unlikely to be related to dorsal screw prominence.
UNASSIGNED: This is a retrospective, observational, descriptive cohort study of adults with operative fixation of a closed DRF and an EPL rupture between 2002 and 2022. Eighteen patients with operative fixation using a volar plate of a closed DRF had an EPL rupture. The cohort consisted of 66% women with an average age of 57.5 years. Median follow-up was 14.5 months.
UNASSIGNED: The incidence of EPL rupture was 0.4% (18/4768). The average time from DRF and DRF fixation to EPL rupture was 3.7 and 3.4 months, respectively. Based on the operative record, in 2 of the 18 patients (11%), the rupture was directly attributable to prominent hardware; however, in 4 of the 18 patients (22%), the rupture was not related to prominent hardware, and the cause was indeterminate in 12 patients (67%). Radiologic analysis of those in the indeterminate group demonstrated that 5 of the 12 patients had screws that had a high probability of being prominent.
UNASSIGNED: The incidence of EPL rupture after volar plating of DRF is between 0% and 1% and usually occurs about 3 months after fixation. Approximately 50% of EPL ruptures are attributable to prominent dorsal screws. Although screw prominence is an important cause of EPL rupture, it is not the sole cause of rupture.

摘要：
■本研究旨在分析一组桡骨远端骨折（DRF）的掌侧锁定钢板术后长伸肌（EPL）破裂的患者，以表征不太可能与背侧螺钉突出有关的破裂发生率。
■这是一个回顾，观察,2002年至2022年期间，对闭合DRF和EPL破裂手术固定的成年人进行描述性队列研究。18例使用闭合DRF的掌侧板进行手术固定的患者发生了EPL破裂。该队列由66％的女性组成，平均年龄为57.5岁。中位随访时间为14.5个月。
■EPL破裂的发生率为0.4%(18/4768)。从DRF和DRF固定到EPL破裂的平均时间为3.7和3.4个月，分别。根据手术记录,18例患者中有2例（11%），破裂直接归因于突出的硬件；然而，18例患者中有4例（22%），破裂与突出的硬件无关，12例患者（67%）的病因不确定。对不确定组患者的放射学分析表明，12例患者中有5例的螺钉很有可能突出。
■DRF掌侧电镀后EPL破裂的发生率在0％至1％之间，通常发生在固定后约3个月。大约50%的EPL破裂可归因于突出的背侧螺钉。尽管螺钉突出是EPL破裂的重要原因，这不是破裂的唯一原因。
