The aim of this study was to evaluate capsulolabral repair in athletes with traumatic anterior glenohumeral instability using magnetic resonance imaging (MRI) and correlate it with clinical and epidemiological data.
A prospective therapeutic clinical study was conducted with 36 athletes undergoing surgical treatment. MRI was performed preoperatively and in the third month postoperatively. The morphology, height, angulation, integrity and density of the repaired capsulolabral tissue were evaluated. Linear and logistic regression models were applied.
A total of 36 athletes were evaluated (mean age 29.64 ± 9.08 years). For all numerical variables (morphology, integrity, angles and heights) the differences were statistically significant, except for the coronal angle and homogeneity. Longer time to surgery or multiple dislocations reduced the improvement in morphology. There were no new episodes of dislocation. In the 3-month radiological evaluation, the integrity of the labrum was present in 97% of the patients, however, all patients still had a heterogeneous labrum.
There are statistically significant differences between the morphology, height and angulation of the labrum between the pre- and postoperative periods of patients operated on for glenohumeral instability. Although the 3-month MRI showed integrity of the labrum in almost all athletes, this tissue still presented altered density even with satisfactory clinical results.
本研究旨在利用磁共振成像(MRI)评估创伤性前盂肱关节不稳运动员的关节囊盂唇修复情况,并将其与临床和流行病学数据相关联。
对36名接受手术治疗的运动员进行了一项前瞻性治疗性临床研究。术前和术后第三个月进行MRI检查。评估修复的关节囊盂唇组织的形态、高度、角度、完整性和密度。应用线性和逻辑回归模型。
共评估了36名运动员(平均年龄29.64±9.08岁)。对于所有数值变量(形态、完整性、角度和高度),除冠状角和同质性外,差异均具有统计学意义。手术时间较长或多次脱位会降低形态学改善程度。没有新的脱位发作。在3个月的影像学评估中,97%的患者盂唇完整,然而,所有患者的盂唇仍不均匀。
接受盂肱关节不稳手术的患者术前和术后期间,盂唇的形态、高度和角度存在统计学显著差异。尽管3个月的MRI显示几乎所有运动员的盂唇完整,但即使临床结果令人满意,该组织的密度仍有改变。
