Abstract：
BACKGROUND: We assessed intraarticular injuries in patients after primary anterior traumatic shoulder dislocation by comparing magnetic resonance arthrography (MRA) results with concomitant arthroscopic findings.
METHODS: All patients with primary traumatic shoulder dislocation who underwent arthroscopic surgery between 2001 and 2020 with preoperative MRA were included in this study. MRA was retrospectively compared with arthroscopic findings. Postoperative shoulder function was prospectively assessed using the Disabilities of Arm, Shoulder and Hand score (quick DASH), the Oxford Shoulder Score (OSS), the Subjective Shoulder Value (SSV), as well as the rate of return to sports.
RESULTS: A total of 74 patients were included in this study. A Hill-Sachs lesion was consistently found in the corresponding shoulders on MRA and arthroscopy in 35 cases (p = 0.007), a Bankart lesion in 37 shoulders (p = 0.004), and a superior labrum from anterior to posterior (SLAP) lesion in 55 cases (p = 0.581). Of all cases, 32 patients were available for a clinical and functional follow-up evaluation. A positive correlation was found between the level of sport practiced and the Oxford Shoulder Score (redislocation subset) (p = 0.032) and between the age at the time of surgery and the follow-up SSV (p = 0.036). Conversely, a negative correlation was observed between the age at the time of surgery and the Oxford Instability Score (redislocation subset) (p = 0.038).
CONCLUSIONS: The results of this study show a good correlation between MRA and arthroscopy. Therefore, MRA is a valid tool for the detection of soft tissue pathologies after primary anterior traumatic shoulder dislocation and can aid in presurgical planning.

摘要：
背景：我们通过比较磁共振关节造影（MRA）结果和伴随的关节镜检查结果来评估原发性创伤性肩关节脱位后患者的关节内损伤。
方法：所有在2001年至2020年期间接受关节镜手术术前MRA的原发性创伤性肩关节脱位患者均纳入本研究。回顾性比较MRA与关节镜检查结果。使用手臂残疾前瞻性评估术后肩关节功能，肩手评分（快速DASH），牛津肩评分(OSS)主观肩值(SSV)，以及体育的回报率。
结果：本研究共纳入74例患者。在35例MRA和关节镜检查中，在相应的肩膀上始终发现Hill-Sachs病变（p=0.007），37肩的Bankart病变（p=0.004），55例（p=0.581），由前到后（SLAP）病变。在所有案件中，32例患者可用于临床和功能随访评估。运动水平与牛津肩评分（再脱位子集）（p=0.032）之间以及手术时的年龄与随访SSV（p=0.036）之间呈正相关。相反，手术时的年龄与牛津不稳定评分(再脱位子集)呈负相关(p=0.038).
结论：本研究结果显示MRA与关节镜检查有良好的相关性。因此,MRA是检测原发性前创伤性肩关节脱位后软组织病变的有效工具，可以帮助进行术前计划。
