Double compression of the ulnar nerve, including Guyon's canal syndrome associated with cubital tunnel syndrome caused by the anconeus epitrochlearis muscle, is a very rare condition. We present a case of double crush syndrome of the ulnar nerve at the wrist and elbow in a 55-year-old man, as well as a brief review of the literature. Although electrodiagnostic findings were consistent with an ulnar nerve lesion only at the elbow, ultrasonography revealed a ganglion compressing the ulnar nerve at the hypothenar area and the anconeus epitrochlearis muscle lying in the cubital tunnel. Careful physical examination and ultrasound assessment of the elbow and wrist confirmed the clinical diagnosis prior to surgery.

목적: 활차상 주근에 의한 지연성 척골 신경 마비 증례를 경험하였기에 보고하고자 한다. 대상 및 방법: 37세 여자가 주관절 부위의 지연성 척골 신경 마비로 수술적 소견상 전형적인 활차상 주근과는 다른 상완골 내상과에서 약 2 cm 상방으로 내상과 능선에서 기시하여 내측 근간막에 부착되는 비전형적인 활차상 주근과 척골신경이 압박되는 소견을 보여 활차상 주근 절제 및 신경 감압술과 척골신경 전방 전위술 시행하였다. 35세 남자가 주관절 부위의 척골 신경 지연성 마비로 수술적 소견상 상완골 내상과 능선에서 기시하여 주두의 내측에 부착하는 전형적인 활차상 주근의 소견을 보였으며, 척골신경이 압박되는 소견을 보여 활차상 주근 절제 및 신경 감압술과 척골신경 전방 전위술을 시행하였다. 결과 및 결론: 저자들은 전형적 활차상 주근에 의한 지연성 척골신경 마비 1예와 전형적 활차상 주근과는 다른 기시부를 가진 비전형적인 활차상 주근에 의한 지연성 척골신경 마비 1예를 경험하여 문헌고찰과 함께 보고하고자 한다.

Objective : We evaluated the clinical manifestation and surgical results following operative treatment of cubital tunnel syndrome (CuTS) caused by anconeus epitrochlearis (AE) muscle. Methods : Among 142 patients who underwent surgery for CuTS from November 2007 to October 2015, 12 were assigned to the AE group based on discovery of AE muscle; 130 patients were assigned to the other group. We analyzed retrospectively; age, sex, dominant hand, symptom duration, and weakness in hand. Severity of the disease was evaluated using the Dellon classification and postoperative symptom were evaluated using disability of arm shoulder and hand (DASH) and visual analogue scale (VAS) scores. Surgery consisted of subfascial anterior transposition following excision of AE muscle. Results : AE muscle was present in 8.5% of all patients, and was more common in patients who were younger and with involvement of their dominant hand; the duration of symptom was shorter in patients with AE muscle. All patients showed postoperative improvement in symptoms according to DASH and VAS scores. Conclusion : The possibility of CuTS caused by AE muscle should be considered when younger patients have rapidly aggravated and activity-related cubital tunnel symptoms with a palpable mass in the cubital tunnel area. Excision of AE muscle and anterior ulnar nerve transposition may be considered effective surgical treatment.
