Recently, collagen therapy has been made available for treating rotator cuff tendon injuries. However, to our knowledge, there are no clinical studies objectively investigating the effect of collagen therapy.
A 53-year-old female patient visited our pain clinic because of pain in the right shoulder. Although she had never experienced trauma and had not overused her shoulder and arm, the patient showed limited range of motion with painful arc syndrome. Moreover, the Neer test and Hawkins-Kennedy test were positive with subacromial tenderness.
The MRI findings revealed partial tears on the articular surface of the anterior supraspinatus tendon in the rotator cuff.
The patient was treated with injections of exogenous collagen at the site of the partial tear under ultrasound guidance.
Follow-up MRI after injection of collagen revealed healing of the previous partial rupture of the tendon without any complications. Moreover, the patient reported reduction in pain and improvement in the movement of her shoulder during the follow-up period.
In this report, we demonstrate healing of a partial tear of the supraspinatus tendon in the rotator cuff after injection of exogenous collagen, as confirmed by MRI.
最近，胶原蛋白疗法已可用于治疗肩袖肌腱损伤。然而，据我们所知，尚无临床研究客观地研究胶原蛋白疗法的效果。
一名53岁女性患者因右肩疼痛前来我们的疼痛诊所就诊。尽管她从未经历过创伤，也没有过度使用肩部和手臂，但患者表现出活动范围受限并伴有疼痛弧综合征。此外，Neer试验和Hawkins-Kennedy试验呈阳性，肩峰下有压痛。
MRI检查结果显示肩袖中冈上肌腱前关节面部分撕裂。
在超声引导下，在部分撕裂部位注射外源性胶原蛋白对患者进行治疗。
注射胶原蛋白后的随访MRI显示，先前的肌腱部分断裂已愈合，无任何并发症。此外，患者报告在随访期间疼痛减轻，肩部活动改善。
在本报告中，我们证明了注射外源性胶原蛋白后，肩袖中冈上肌腱部分撕裂得以愈合，这一点通过MRI得到了证实。
