摘要

A distal posterior interosseous nerve (DPIN) neuroma related to prior surgery of the wrist can lead to disabling chronic pain. Ultrasound may represent a useful diagnostic tool due to its high resolution and ability to detect iatrogenic neuromas along small nerves of the limbs. However, the utility of ultrasound in the evaluation of both the normal sonographic appearance of the DPIN and traumatic neuromas is limited. We present a series of two patients who suffered from chronic dorsal wrist postoperative pain, where ultrasound detected histologically confirmed DPIN neuromas. After DPIN resection, the pain of our two patients completely disappeared without any functional deficit.
