By combining high-frequency and contrast-enhanced ultrasound (CEUS), the position of the severed end of a finger extensor tendon injury and the injury classification can be determined as part of a comprehensive preoperative evaluation in clinical practice. However, there have been no reports of high-frequency ultrasound combined with CEUS for the preoperative diagnosis of human finger extensor tendon injury.
One case of complete rupture of the extensor tendon was diagnosed by ultrasound, which was completely consistent with the surgery; one case of incomplete rupture was ultimately confirmed clinically; and one case of distal phalangeal bone base avulsion fracture with tendon contusion and missed diagnosis on the first radiographic examination was confirmed by follow-up radiographic examination.
Different types of finger extensor tendon injuries exhibit distinctive contrast-enhanced ultrasonography findings. Combined high-frequency and contrast-enhanced ultrasound can accurately locate the position of the severed end of the finger extensor tendon injury before surgery while observing the contrast agent filling area to clarify injury classification, providing a reliable imaging basis for clinical practice and ultimately developing personalized diagnosis and treatment plans for patients to ensure minimal trauma and pain, as well as optimal treatment effects.
通过结合高频超声和超声造影（CEUS），在临床实践中，作为术前综合评估的一部分，可以确定手指伸肌腱损伤的断端位置和损伤分类。然而，尚无关于高频超声联合CEUS用于人类手指伸肌腱损伤术前诊断的报道。
1例伸肌腱完全断裂经超声诊断，与手术结果完全一致；1例不完全断裂最终经临床确诊；1例远节指骨基底撕脱骨折伴肌腱挫伤，首次X线检查漏诊，经随访X线检查确诊。
不同类型的手指伸肌腱损伤表现出独特的超声造影表现。高频超声与超声造影相结合，可在术前准确定位手指伸肌腱损伤的断端位置，同时观察造影剂充盈情况以明确损伤分类，为临床实践提供可靠的影像学依据，最终为患者制定个性化的诊断和治疗方案，确保创伤和疼痛最小化，以及达到最佳治疗效果。
