探讨手指肌腱损伤在超声图像上可能出现的特征,评估高频肌骨超声在手指肌腱损伤中的诊断价值。
本研究为一项回顾性研究。连续性收集2021年1月至2024年12月在安徽医科大学第二附属医院临床可疑诊断为手指肌腱断裂,并接受手指肌腱缝合术的患者。术前对患者进行临床评估、高频肌骨超声观察,必要时增加超声被动运动检查,总结归纳手指肌腱断裂、撕裂的超声声像图表现,以手术探查为金标准,计算临床诊断以及超声诊断的准确性。
共计纳入42例手指肌腱损伤的患者。临床诊断:28例患者为伸肌腱断裂,14例患者为屈肌腱断裂。手术诊断:28例伸肌腱损伤的患者中18例手术诊断为指伸肌腱断裂,10例手术诊断为指伸肌腱撕裂;14例屈肌腱损伤的患者中10例手术诊断为指屈肌腱断裂,4例手术诊断为指屈肌腱撕裂。超声诊断伸肌腱损伤:19例患者指伸肌腱断裂,表现为伸肌腱连续性中断,10例(10/11)超声被动运动消失;9例患者指伸肌腱撕裂,表现为伸肌腱肌纤维局部中断、肿胀、变细,2例(2/3)超声被动运动存在,其中4例患者伴发撕脱性骨折。伸肌腱损伤临床诊断符合率为64.29%(18/28),超声诊断符合率为96.43%(27/28)。超声诊断屈肌腱损伤:11例患者指屈肌腱断裂,表现为伸肌腱连续性中断,9例(9/9)超声被动运动消失;3例患者指屈肌腱撕裂,表现为肌纤维局部中断,未达全层,1例(1/2)超声被动运动存在。屈肌腱损伤临床诊断符合率为71.43%(10/14),超声诊断符合率为92.86%(13/14)。
高频肌骨超声对手外伤所致的手指肌腱损伤具有较高的诊断价值,且在超声检查过程中增加被动运动检查,有助于增加手指肌腱损伤诊断的准确性。

To explore the ultrasound features of finger tendon injuries and evaluate the diagnostic value of high-frequency musculoskeletal ultrasound in such injuries.
From January 2021 to December 2024, consecutive patients with suspected finger tendon rupture and suture in the Second Affiliated Hospital of Anhui Medical University were collected. Before operation, the patients were evaluated clinically and examined by high-frequency musculoskeletal ultrasound, and ultrasound at passive movement was added in a part of patients. The ultrasound manifestations of finger tendon rupture and tear were summarized. The accuracy of clinical diagnosis and ultrasonic diagnosis was calculated by using surgical exploration results as the gold standard.
A total of 42 patients with finger tendon injuries were included. Clinical diagnosis suggested extensor tendon rupture in 28 patients and flexor tendon rupture in 14. Of 28 patients with extensor tendon injuries, 18 were surgically diagnosed with extensor tendon rupture and 10 with extensor tendon tear; of 14 patients with flexor tendon injuries, 10 were surgically diagnosed with flexor tendon rupture and 4 with flexor tendon tear. Ultrasonic diagnosis of extensor tendon injuries suggested 19 cases of extensor tendon rupture, manifested as extensor tendon continuity interruption, of which 10 (10/11) had disappearance of ultrasonic manifestations at passive movement; 9 cases of extensor tendon tear, manifested as local interruption of extensor tendon muscle fibers, swelling, and thinning, of which 2 (2/3) had ultrasonic manifestations at passive movement and 4 were accompanied by avulsion fracture. The coincidence rate of clinical diagnosis of extensor tendon injuries was 64.29% (18/28), and that of ultrasonic diagnosis was 96.43% (27/28). Ultrasonic diagnosis of flexor tendon injuries suggested 11 cases of flexor tendon rupture, manifested as extensor tendon continuity interruption, of which 9 (9/9) had disappearance of ultrasonic manifestations at passive movement; and 3 cases of flexor tendon tear, manifested as muscle fiber local interruption, not reaching the full layer, of which 1 (1/2) had ultrasonic manifestations at passive movement. The coincidence rate of clinical diagnosis was 71.43% (10/14), and that of ultrasonic diagnosis was 92.86% (13/14).
High-frequency musculoskeletal ultrasound has high diagnostic value for finger tendon injuries. Adding passive motion examination in the process of ultrasound examination can increase the accuracy of finger tendon injury diagnosis.
