Morton’s neuroma is a common and painful foot condition that primarily affects women around the age of 50. It is characterized by the compression of the common plantar digital nerves, which leads to lesions in the nerve sheath and an increase in nerve thickness, resulting in compression and pain. The neuroma is caused by the nerve being trapped between the ground, the metatarsal heads, and the deep transverse intermetatarsal ligament, causing ischemia and fibrotic scar tissue formation. The surgical procedure involves using ultrasound guidance to reach the neuroma and dissect the deep transverse intermetatarsal ligament. Local anesthesia is used, and the ligament is sectioned using a hook knife. The surgical wound is not closed but covered with a dressing. Postoperative care includes wound care instructions, elevation of the foot, and application of cold packs. Painkillers are prescribed, and patients can resume their daily activities after 48 h, with caution for the first 3 weeks. In conclusion, Morton’s neuroma is a painful foot condition that can be diagnosed through clinical examination and ultrasound imaging. Conservative treatments are usually the first line of treatment, but surgical intervention may be necessary. Endoscopic and ultrasound-guided techniques have shown promising results in providing relief for patients.

摘要

Morton’s neuroma is a common and painful foot condition that primarily affects women around the age of 50. It is characterized by the compression of the common plantar digital nerves, which leads to lesions in the nerve sheath and an increase in nerve thickness, resulting in compression and pain. The neuroma is caused by the nerve being trapped between the ground, the metatarsal heads, and the deep transverse intermetatarsal ligament, causing ischemia and fibrotic scar tissue formation. The surgical procedure involves using ultrasound guidance to reach the neuroma and dissect the deep transverse intermetatarsal ligament. Local anesthesia is used, and the ligament is sectioned using a hook knife. The surgical wound is not closed but covered with a dressing. Postoperative care includes wound care instructions, elevation of the foot, and application of cold packs. Painkillers are prescribed, and patients can resume their daily activities after 48 h, with caution for the first 3 weeks. In conclusion, Morton’s neuroma is a painful foot condition that can be diagnosed through clinical examination and ultrasound imaging. Conservative treatments are usually the first line of treatment, but surgical intervention may be necessary. Endoscopic and ultrasound-guided techniques have shown promising results in providing relief for patients.
