권영준,김태성,임영진,이봉암,임언,김국기,Kwon, Yung-Jun,Kim, Tae-Sung,Lim, Young-Jin,Rhee, Bong-Arm,Leem, Won,Kim, Gook-Ki 대한신경외과학회 2000 Journal of Korean neurosurgical society Vol.29 No.3
The carpal tunnel syndrome is one of the most common entrapment neuropathy. Surgical treatments consist of conventional open technique, alternative technique using retinaculatome, and endoscopic surgery. This study compares the outcomes of surgical treatment of carpal tunnel syndrome following conventional versus endoscopic release. The authors reviewed 56 cases of 33 patients with carpal tunnel syndrome treated surgically in our institute from January 1991 to May 1998. The follow-up evaluation was possible in 36 cases of 20 patients who had conventional release and in 11 cases of 7 patients with endoscopic release. The following parameters were evaluated for comparison : improvement of symptom, return to normal work, recovery of strength of grip and pinch, rate of complication, follow-up electrophysiologic finding. Compared with open decompression, the group of endoscopic decompression needed significantly less time to go back to work(p<0.001). Also strength of grip and pinch improved faster in the group of endoscopic decompression as well, compared with open decompression(p<0.05). These results indicate that endoscopic procedure is an excellent, minimally invasive method to treat carpal tunnel syndrome, performed by surgeons who are fully aware of the anatomy.

근위조립형 무시멘트 대퇴스템을 이용한 인공관절 재치환술
박명식 ( Myung Sik Park ),임영진 ( Yung Jin Lim ),이주홍 ( Ju Hong Lee ) 대한고관절학회 2006 Hip and Pelvis Vol.18 No.1
목적: 인공고관절 재치환술에 있어서 근위조립형 무시멘트 스템(Link MP hip reconstructive system)을 이용한 결과를 임상적 방사선학적 분석을 하고자 한다. 대상 및 방법: 1997년 1월부터 서 2002년 12월까지 인공관절 재치환술을 받은 환자 95명을 대상으로 하여 최소 24개월 최대 8년 4개월 이상 추시가 가능 하였던 57명 (57례)을 대상으로 하였다. 재치환술의 원인으로는 무균성이완이 45례, 감염성 이완으로 재-재치환경우가 5례, 대퇴스템과 관련된 골절이 6례, 재발성 탈구가 1례였다. 골결손의 정도는 Paprosky 분류에 의거하였으며 IIIA 이하가 46례, IIIB 이상이 11례였다. 결과: Harris hip score는 술 전 47에서 87.6으로 향상되었으며, 최종 추시상 환자의 만족도는 87.7%이며 원위 대퇴스템의 골형성에 의한 고정은 94.7%에서 관찰되었으며. 수술 중 합병증은 대전자부 골절 2례, 근위 대퇴골 골절이 2례였으며, 수술 후 합병증으로는 대퇴스템 침강이 5례(0-5 mm in 2hips, >20 mm in 3 hips), 심부 감염이 4례에서 관찰 되었으며, 대전자부 불유합과 동반된 아탈구 1례, 절골술 부위 불유합이1례, 고정나사의 이완이 1례에서 관찰 되었다. 근위-원위부품 모두 재치환은 20 mm이상 침강을 보인 3례중 2례에서 시행되었으며. 근위부품만을 교환한 경우는 3례로 불유합과 전자부 전위가 2례, 고정나사 이완1례였다. 최종추시상 대퇴스템 원위골절의 발생은 없었다. 결론: 인공관절 재치환술에서 근위 조립형 대퇴스템은 전염각 조정과 하지 길이의 조정이 편리하며, 감염 시 원위부 스템을 유지 한 채로 근위부만 단계적인 치환을 할 수 있었다. 조립형 재치환스템은 근위 대퇴골의 소실이 있는 증례에서 유용하게 사용 되었으며 보다 성공적인 결과를 얻기 위하여서는 섬세한 수술 수기와 합병증의 예방이 중요 할 것으로 사료 된다. Purpose: The goal of study was to evaluate the clinical and radiographic performance of the proximal modular cementless femoral stem for use in revision total hip arthroplasty. Material and method: Fifty seven patients (57 hips) were followed for longer than 24 months or up to 8.4 years after performing revision total hip arthroplasty with using the proximal modular cementless femoral stem between January 1997 and December 2002. The preoperative diagnosis included 45 cases of aseptic loosening, 5 cases of septic loosening (re-revision operation), 6 cases of periprosthetic fracture and 1 case of recurrent dislocation. The bone deficiencies were classified according to the Paprosky classification: there were 27 cases of Type I and II, 19 cases of Type IIIA, 9 cases of Type IIIB and 2 cases of Type IV. Results: The average Harris hip score improved from 47 to 87.6. Clinically satisfactory results were noted in 50 patients (87.7%). Radiographically, distal stable fixation was observed in 54 patients (94.7%). Intraoperative complications included two greater trochanteric fractures and two proximal femur fractures. Postoperative complications included 5 femoral stem subsidences (2hips< 5mm, 3 hips>20mm), 4 deep infections, 2 non-unions of the greater trochanter and the osteotomy site and set screw dissociation was noted in 1 case. 5 proximal component changes were done due to progressive subsidence in two cases, non-union at the osteotomy site and trochanteric displacement in two cases and set screw dissociation in one hip. For the infection cases, the proximal segment was removed and re-revised with a 2nd stage operation. (Ed note: check this.) The subsidence of the femoral stems was showed in 3 Paprosky grade IIIA cases and in 2 cases of grade IIIB or more. There was no postoperative periprosthetic fracture observed at the last follow-up. Conclusion: Revision total hip arthroplasty using the proximal modular cementless femoral stem showed good results in the face of the infection of the proximal component and deficient proximal bony support. This procedure appears to be convenient for the surgeon to correct anteversion of the femoral head and leg length discrepancy.

Lithium Carbonate가 白鼠 賢臟에 미치는 影響에 關한 電子顯微鏡的 硏究
이형영,이무석,이귀행,임영진,노승호 大韓神經精神醫學會 1983 신경정신의학 Vol.22 No.2
To investigate the effects of lithium carbonate on rat (Sprague-Dawley) kidney cells, light and electron microscopic observation were made. Experimental rats received daily intraperitoneal injections of lithium carbonate in doses of 30 or 150mg/kg. These animals were killed on 6.13.20.30 days after the first injection. 1) In the distal convoluted tuble, the 30mg/kg lithium carbonate dosages caused progressive mitochondrial swelling, dilatation of cisternae of rough endoplasmic reticulum, generalized reduction of cell organelles, irregular basal infolding and diiatation of Golgi apparatus. In the proximal tuble, same dose of lithium carbonate caused appearance of lyscsomes, mitochondrial swelling, dilatation of cisternae of rough endoplasmic reticulum, and appearance of dense bodies. These cellular changes were more marked with the lapse of time. 2) In the distal convoluted tuble, the 150mg/kg lithium carbonate dosages produced destruction of basal infolding(which was more severe compared with those 30mg/kg dosage), many vesicles in cytoplasm and cytoplasmic swelling. In the proximal tuble, the same dosages of lithium caused appearance of lysosome, mitochondrial swelling, loss of mitochondrial crest, appearance of many vesicles. These celluar changes were also more marked with the lapse of time. 3) The present study demonstrated that usual dosage of lithium carbonate do affect the structure of the rat kidney.
