Background It can be difficult to select an appropriate flap for various defects on the hand. Although defects of the hand usually must be covered with a skin flap, some defects require a flap with rich blood supply and adequate additive soft tissue volume. The authors present their experience with the anconeus muscle free flap in the reconstruction of various defects and the release of scar contractures of the hand. Methods Ten patients underwent reconstruction of the finger or release of the first web space using the anconeus muscle free flap from May 1998 to October 2013. Adequate bed preparations with thorough debridement or contracture release were performed. The entire anconeus muscle, located at the elbow superficially, was harvested, with the posterior recurrent interosseous artery as a pedicle. The defects were covered with a uniformly trimmed anconeus muscle free flap. Additional debulking of the flap and skin coverage using a split-thickness skin graft were performed 3 weeks after the first operation. Results The average flap size was $18.7cm^2$ (range, $13.5-30cm^2$). All flaps survived without significant complications. Vein grafts for overcoming a short pedicle were necessary in 4 cases. Conclusions The anconeus muscle free flap can be considered a reliable reconstructive option for small defects on the hand or contracture release of the web space, because it has relatively consistent anatomy, provides robust blood supply within the same operative field, and leads to no functional loss at the donor site.

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.

Fixation of radial head fracture with minimally invasive posterior approach remains a significant challenge. The aim of this study was to determine the feasibility of trans-anconeus posterior elbow approach and to observe lateral ulnar collateral ligament (LUCL) in extended elbows. This cadaveric study was performed in twenty upper limbs of fresh fixed adult male cadavers. An oblique incision was made in the middle segment of anconeus until the lateral ligament complex and the joint capsule had been revealed. A deep dissection was explored to observe the anatomical relationship of the LUCL to the anconeus. Measurements of the LUCL were recorded while the elbow was fully extended. The mean distance between the edge of the radial head and the proximal insertion of the LUCL was 13.3 mm (11.5-16.2 mm); the mean distance between the edge of the radial head and the distal insertion of the LUCL was 20.9 mm (19.2-23.4 mm); the distance between the edge of the radial head and the distal edge of the annular ligament was 11.2 mm (8.22-11.7 mm). By estimate correlation of the previous measurements, the direct and accessible way to expose the posterolateral articular capsule of the elbow joint was through a window in medial 2/3 of the middle segment of anconeus muscle. These trans-anconeus approach is useful. It provides good visualization, facilitates applying the implants, and lessens the risk of radial nerve injury. Awareness of the anatomy is mandatory to avoid injury of LUCL.

본 연구는 반복신경자극검사시 통상적으로 사용하는 근육에 비근과 팔꿈치근을 포함시켜 중증근무력증의 유형에 따라 RNST를 시행할 경우 유형별로 가장 유용한 근육이 무엇인지를 알아보았는데, 제I형의 경우에는 안면근육인 안윤근이나, 또는 통계적으로 차이가 없는 비골근이 RNST 검사에 유용한 것으로 생각되고 제 IIa 또는 IIb형의 경우에는 상지근육인 팔꿈치근이 가장 유용한 근육으로 생각되며 팔꿈치근이 정상일 경우 안면근육을 이용하는 것이 진단율을 높일 수 있을 것이라고 생각된다. 결론적으로 중증근무력증에서 반복자극검사시 I형일 경우 진단에 있어서 안윤근을 먼저 검사하고 필요할 경우 비골근으로 대치할 수 있으며, IIa형 이상의 중증근무력증 환자에서는 팔꿈치근을 우선적으로 검사하는 것이 진단적 민감성을 높일 수 있을 것이라고 생각된다.
