Abstract

This study is Carpal tunnel syndrome(CTS) disorder of median nerve at wrist. It is usually diagnosed through clinical manifestation and Nerve Conduction Study(NCS). NCS of the median nerve before and after operation were compared in twenty four patient's with CTS, in order to seventeen patient's evaluate the prognostic value of that findings. Analysis result symptom profile of CTS in total number of patient's 17 (Female:17, Male:0), 21 hands (Rt:9, Lt:4, Both:4), Ages(31~60), Mean duration of symptom months($46.6{\pm}36.1$), Mean interval between 1st and 2nd NCS months($20.5{\pm}7.1$), Sensory symptoms(Tingling:21, Numbness:19, Noctunal paresthesia:17), Motor symptoms(Thenar atrophy:20, Trigger finger:2, Morning stiffness:3), Post-operative symptoms(Free:38.1%, >50% improve:52.4%, <50% improve:9.5%). NCS was normal range after operation than before in Sensory nerve conduction study 4 patients's and Motor nerve conduction study 5 patients. Surgery before and after Sensory nerve action potential (SNAP) responses showed improvement over the previous results. Forward by the patient's occupation and occupation patterns of CTS, other treatment methods and surgical treatment of CTS by comparing the degree of improvement to identify and correct nerve conduction study to judge whether the patient's operation.

본 연구에서 손목터널 증후군의 발생은 손목의 정중 신경 손상에 의한다. 일반적으로 임상 발현 및 신경전도검사를 통해 진단된다. 신경전도검사는 손목터널 증후군 환자 24명을 대상으로 하여 수술 전 후 정중 신경을 비교 평가 하였고, 이중 17명을 대상으로 평가 분석 하였다. 손목터널 증후군 증상의 분석 결과는 전체 환자 수 17명(여:17, 남0), 21손(오른쪽:9, 왼쪽:4, 양쪽:4), 연령(31~60세), 평균 유병 기간 ($46.6{\pm}36.1$), NCS의 첫 번째와 두 번째 검사 간격 개월 수($20.5{\pm}7.1$), 감각 신경(감각 이상:21, 감각 저하:19, 야간통증:17), 운동 신경(무지구 위축:20, 방아쇠 손가락:2, 조조 경직:3), 수술 후 증상은(증상 소실:38.1%, >50% 개선:52.4%, <50% 개선:9.5%) 이었다. 신경전도검사는 수술 후 감각 신경전도검사에서 4명, 운동 신경전도검사에서 5명이 정상 범위 이었다. 수술 전 후의 감각신경활동전위 반응은 이전 결과보다 호전된 결과를 보였다. 앞으로 환자의 직업에 의한 손목터널증후군의 양상과 직업별 수술외적인 치료방법과 수술치료방법을 비교하여 손목터널증후군의 호전정도를 파악하고 정확한 신경전도검사를 통해 환자의 수술여부를 판단해야 된다.
