It is well known that tardy ulnar nerve palsy occurs with cubitus valgus deformity as a late complication after a nonunion of lateral condyle fracture of the humerus in childhood. On the other hand, cubitus varus deformity often results from malunion of supracondylar fractures of the humerus. However, reports of tardy ulnar nerve palsy in cubitus varus deformity are few. We report a patient with bilateral cubitus varus deformities with bilateral tardy ulnar nerve palsy which was confirmed with EMG. She was treated by step cut osteotomy(DeRosa and Graziano) with sub­cutaneous anterior transposition of ulnar nerve.

Tardy ulnar nerve palsy is ulnar neuropathy at or around elbow and commonly evaluated in the electromyography laboratory. However, ulnar neuropathy at the elbow due to neurofibroma is rare. Neurofibromas are tumors that arise within nerve fasciculi and anywhere along a nerve from dorsal root ganglion to the terminal nerve branch. We report one case of ulnar neuropathy at the elbow due to neurofibroma. Patient had paresthesia on the left 5th finger and there had been left hypothenar atrophy since 2 months ago. Tinel's sign was positive at left elbow. As a result of electromyography, there were suggestive of right ulnar neuropathy at or around elbow, referred to as tardy ulnar nerve palsy. Ultrasonography showed a diffuse tortuous thickening with multiple neurofibromas arising from individual fascicles of the ulnar nerve in cubital tunnel area. Surgery was then performed to release cubital tunnel of left elbow, then the patient's symptoms improved.

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.

Purpose : Cubitus varus deformity has been reported to cause ulnar neuropathy. We present five cases of tardy ulnar nerve palsy due to cubitus vus and analyzed the factors related to the nerve plasy caused by the deformity. Materials and Methods : Three men and two women were reviewed retrospectively and the mean age of the patients were 26 (range, 14-38). The average interval from initial fracture to nerve palsy was 19 years (8-32 years). The severity of symptoms, according to McGowan's classification, was grade I of 2 patients, grade Ⅱ of 3 patients. Carrying angle was an average of 18。 (30° -45° ). Internal rotation angle measured by Yamamoto's method was an average of 33° (30° -45° ). Results ㆍ The mean follow-up period was 53 months (35-70 months). Elbow pain and numbness of the fingers were relieved shortly after surgery. It revealed that anterior subluxation of the nerve due to internal rotation deformity and compression of the nerve between the medially shifted medial head of triceps and the medial epicondyle. Conclusion : The major entrapment point of the nerve is the fibrous band between the two heads of the flexor carpi ulnaris. The severe internal rotation deformity may contribute the cause of tardy ulnar nerve palsy in cubitus varus deformity.

Neglected adult Monteggia fracture could induce the pain, instability and malformation of elbow. Especially, compared with the chronic Monteggia fracture of child, that of adult is difficult to treat and could concur with valgus instability and deformity, limitation of range of motion and tardy ulnar nerve palsy. But recently, the chronic Monteggia fracture of adult could be treated by the 3.5 mm compression plate (DCP) or 3.5 mm pelvic reconstruction plate, so that the result improved more and more. The treatment of choice of the chronic Monteggia fracture of adult is the corrective osteotomy and reduction of radial head or resection of radial head. We experienced two patients who had neglected Monteggia fracture over 1 year 6 months and 25 years respectively and we want to report the result of surgical treatment of chronic Monteggia fracture of adult.
