Traumatic ruptures of flexor tendons as a result of blunt trauma without an associated pathologic condition are rare. This is a case of a midsubstance flexor tendon rupture as a result of closed direct trauma. The patient sustained a flexor digitorum profundus (FDP) rupture 1 cm proximal to its insertion on his right ring finger without any accompanying laceration. Additionally, this case highlights the utility of ultrasound in diagnosing ruptured flexor tendon, which has been demonstrated in prior studies.
钝性创伤导致的屈肌腱外伤性断裂且无相关病理状况的情况较为罕见。这是一例因闭合性直接创伤导致的屈肌腱中段断裂病例。患者右环指的指深屈肌（FDP）在其止点近端1厘米处发生断裂，且无任何伴随的撕裂伤。此外，该病例凸显了超声在诊断屈肌腱断裂方面的效用，先前的研究已证实了这一点。
