본 연구는 초기 손목터널증후군으로 진단된 환자의 정중신경(median nerve)과 자신경(ulnar never)의 및 F파를 대조군과 비교 분석하여 초기 손목터널증후군의 진단에서 F파가 유용한 지표가 될 수 있는지 알아보고자 하였다. 신경전도검사 결과의 주요 지표인 말단잠복기, 말단진폭, 손바닥-손목 구간의 감각신경전도속도 및 F파 잠복기를 대조군과 t-test 검정으로 비교분석하고, 또한 주요 지표간의 상관성 분석을 위하여 상관분석을 실시하였다. 연구결과, 대조군과 초기 손목터널증후군 환자의 정중신경 말단잠복기 비교에서 두 군 간에 유의성이 높은 것으로 나타났다(p<0.001). 정중신경의 감각신경전도속도 비교에서는 대조군과 손목터널증후군 간의 유의성이 높은 것으로 관찰되었다(p<0.001). 후기반응검사인 F파 잠복기 분석에서 정중신경의 경우 대조군과 손목터널증후군간 높은 유의성(p<0.001)을 보였으나, 자신경의 경우는 차이가 없는 것으로 나타났다. 상관분석 결과는 감각신경전도속도와 말단잠복기, F파와 말단잠복기에서 모두 상관성이 있는 것으로 나타났다. 이러한 결과로, F파는 말단잠복기, 감각신경전도속도와 같이 손목터널증후군의 진단에 있어 유용한 지표가 될 수 있다고 사료된다.

The authors present an extremely rare case of a pseudoaneurysm of the ulnar artery as a complication of a two-portal endoscopic carpal tunnel release (ECTR). A 70-year-old man with chronic renal failure and on maintenance hemodialysis with a left arteriovenous fistula presented with paresthesia of his right hand. A clinical diagnosis of right carpal tunnel syndrome was confirmed by ultrasonography and an electro physiologic study. He underwent two-portal ECTR, and the paresthesia was much improved. However, he presented to us one month after operation with severe pain, a tender mass distal to the right wrist crease and more aggravation of the paresthesia in the ulnar nerve distribution. Doppler ultrasound was performed and revealed a hypo echoic lesion 20 mm in diameter in the right palm, with arterial Doppler flow inside connected to the palmar segment of the ulnar artery. An ulnar artery pseudoaneurysm was diagnosed and treated by ultrasound-guided percutaneous thrombin injection. Transverse color Doppler ultrasound image showed complete thrombosis of the pseudoaneurysm and flow cessation after a total injection of 500 units of thrombin. The symptoms were also improved.

Purpose: Radial and ulnar arteries are two major arteries responsible for the blood supply of the hand. We experienced early recurrent thrombosis of ulnar artery after arteriorrhaphy in a patient with rupture of ulnar and radial arteries due to glass injury. Thus, we thought this would require reviews. Method: 41 - year - old female patient was presented for the laceration of right wrist due to glass injury. Operative findings revealed the rupture of radial artery, ulnar artery, ulnar nerve and most of the flexor tendons. We performed three consecutive operations because of the recurrent arterial thrombosis in ulnar artery. Arteriorrhaphy was performed in each operation and the interpositional vein graft was performed in the final operation. Result: Consequently, doppler ultrasonography was performed on twentieth postoperative day and fair flow in the ulnar artery was visualized. Pathologic examination of the artery revealed no histopathologic abnormalities. Conclusion: It is not a matter of ease to follow up the patients with rupture of radial or ulnar arteries. Obstruction of the repaired artery is also not easy to detect because it usually presents no definite symptoms. We could detect the obstruction of the artery following arteriorrhaphy with the doppler ultrasonography in less than a week postoperatively, and repeated operations were followed. We reviewed the causes and factors affecting the thrombosis and hereby report with literature review.

We report a case of 44 years old male patient with neuroma-in-continuity of ulna nerve. In the patient's past history, he had received operative treatment for the open supracondylar fracture of right distal humerus and ulnar nerve injury at 10 years ago, and neurolysis was tried 2 times due to severe neuropathic pain. Despite of these operations, the symptom was not improved. In operative field, we noticed neuroma-in-continuity and decided to resect the neuroma until normal nerve fascicle was noted. The nerve cable graft was done with auto sural nerve on the defect site and the nerve was wrapped with small saphenous vein. At post operative 7 months, pain was markedly decreased and sensory recovery was slightly improved and patient was satisfied with the result.

Background : The term "mononeuropathy multiplex" means simultaneous or sequential involvement of individual noncontiguous nerve trunks, evolving over days to years. The aim of this study was to delineate the causes, clinical features, and detailed electrophysiological findings in the patients with mononeuropathy multiplex. Methods : We analyzed the medical records of 22 patients with mononeuropathy multiplex confirmed on electrophysiological studies in Inje University Seoul Paik Hospital, Seoul Municipal Boramae Hospital, and Seoul National University Hospital between 1991 to 2000. Results : The number of male and female patients was equal. The mean age was 48 years with a peak incidence in the sixth decade. The etiology could be divided into vasculitis(11 patients) or non-vasculitis group. In vasculitis group, Churg-Strauss syndrome, polyarteritis nodosa, and rheumatoid arthritis were included. The non-vasculitis group included diabetes mellitus, leprosy, and Guillain-Barre syndrome. Ulnar and median nerves were most commonly involved(91%). In descending order of frequency, peroneal, posterior tibial, sural, and radial nerves were also involved. Bilateral involvement occurred most commonly in ulnar nerve. The symptoms and signs of mononeuropathy multiplex were the initial manifestations in 12 patients(55%), which was more frequent in vasculitis group(73%). Nerve conduction abnormalities could be divided into axonal, demyelinating, or mixed type. Most(91%) of the patients in vasculitis group revealed axonal type abnormalities. The location of the nerve lesion was frequently related to potential site of entrapment in demyelinating type. Conclusions : Mononeuropathy multiplex is the presenting features of the etiological disease frequently, especially in vasculitis group. Nerve conduction studies(NCS) reveals not only axonal type but also demyelinating type abnormalities. The etiological diseases were different in each type. Therefore, NCS is very helpful for the early etiological diagnosis and therapeutic implication in the patients with mononeuropathy multiplex.

Objectives: This study examined the natural history of symptomatic patients who did or did not display abnormal results on nerve conduction studies (NCS). Methods: Forty hundred fifty adults were selected among a total of 578 residents who participated in the health examination in a rural Korean district. A symptom questionnaire and NCS were used to diagnose ulnar neuropathy at the elbow (UNE). There were 6.4% of the subjects with UNE, 5.1 % of the subjects showed symptoms without a NCS, and 84.2% of the subjects who were asymptomatic. One year later, 20 symptomatic limbs with an abnormality on the ulnar NCS and 22 symptomatic limbs without any abnormality in the ulnar NCS were enrolled in a follow-up study. The natural history of UNE was evaluated by examining the changes in the clinical and electrodiagnostic examinations. Results: The 1-year follow-up of the enrolled limbs found that for the symptomatic limbs with an abnormality on the NCS, the degree of severe of the clinical grade changed from 20% to 10%. In contrast, for the symptomatic limbs that were without any abnormality in the NCS, the change of the severe degree of the clinical grade was from 0% to 18.2%. Also, for the electrodiagnostic change, only symptomatic limbs without NCS abnormalities showed significant changes in motor latency, amplitude and conduction velocity at the 1-year follow-up. Conclusions: The 1-year follow-up study revealed symptomatic limbs that were without any abnormality on the ulnar NCS were more likely to progress than the symptomatic limbs with an abnormality on the ulnar NCS.
