골조송증이 있는 노년층 불안정 대퇴골 전자부 골절에 대한 치료 : 양극성 고관절 반치환술

It has been known that the hemiarthroplasty of the hip with bipolar prosthesis is the one of primary treatment methods for management of unstable intertrochanteric hip fracture, especially in severe osteoprotic patients. Additionally this operative treatment allows early full weight bearing and has many merits for the patient to return to the preinjury functional level. But we think that this operative method has several considerable points for the more effective treatment technique in unstable osteoporotic intertrochanteric fractures. We review the nine interochanteric comminuted fractture patients treated with bipolar prostheses at the Department of Orthopedie Surgery of Ewha Womans University Mok-Dong Hospital from September, 1993 to June, 1994. The considered points are as follows: 1) The difficult problem is to judge the intraoperative head-neck length. which is reduced by the tension of the fascia between gluteus medius and vastus lateralis fascia, preoperative measuring the head-neck length with transparent template, level of the tip of greater trochanter and prosthetic femoral head, and range of motion of hip of greater trochanter and prosthetic femoral head, and range of motion of hip joint under the tr1al reduction. 2) The operative approach is the other considerable point for the exposure of medial cortical buttress and lesser trochanter in reducing and maintaining principal fragments, and for the accurate anteversion angle of femur. 3) Bipolar hemiathroplasty technique is not effective in reducing the operative time and the blood loss amount in operative field, wspecially in comminuted interochanteric fracture treatment.

목적: 슬관절 전치환술 시 경골 후경사각의 방사선학적 평가에서 기준이 되는 축을 슬관절 측면 방사선 사진상에서 찾고자 하였다. 대상 및 방법: 슬관절 전치환술을 시행받은 37명 52예의 슬관절 측면 방사선 사진과 경골 전장 측면 방사선 사진을 촬영하였다. 경골 전장 측면 사진 상 경골 후경사각을 측정하였으며 슬관절 측면 사진상 근위 경골의 해부학적 축, 근위 경골 전방 및 후방 피질부 연장선, 근위 비골의 해부학적 축을 기준으로 경골 후경사각을 측정하여 이들과 경골 전장 측면 사진상 측정한 경골 후경사각간의 차이를 구하였고 이들의 상관관계를 비교하였다. 결과: 슬관절 측면 사진 상에서 근위 경골 전방 피질부의 연장선을 기준으로 측정한 후 경사각은 경골 측면 사진상에서 측정한 후경사각 보다 평균 0.15(전 경사 3.95도-후 경사 5.57도)도 전 경사를 이루며, 이 차이는 근위 경골의 해부학적 축, 근위 경골 후방 피질부 연장선, 근위 비골 해부학적 축을 기준으로 하여 측정한 후경사각과 경골 측면 사진 상 측정한 후경사각간의 차이에 비해 의미있게 적은 차이를 보였다(p<0.001). 결 론: 슬관절 전치환술 후 슬관절 측면 사진 상에서 근위 경골 전방 피질부의 연장선을 기준으로 경골 후경사각을 측정하는 것이 경골 전장의 후경사각을 가장 정확히 재현하는 것으로 사료된다. Purpose: This study evaluated the radiological reference line of the posterior slope angle on the lateral view of a plain knee radiograph. Materials and Methods: The lateral view of the plain knee and whole tibia radiographs were analyzed from thirty seven patients (fifty-two cases) who had undergone total knee arthroplasty. The posterior slope angle was measured on the lateral view of the tibia. On the lateral view of the knee, the posterior slope angle was measured with reference to the proximal tibial anatomical axis, the proximal tibial anterior cortical line, the proximal tibial posterior cortical line and the proximal fibular anatomical axis. These values were compared with the posterior slope angle measured on the whole tibia lateral view. Results: The posterior slope angle, which was measured by the anterior cortical line as a reference line, was tilted slightly anteriorly to that measured by the whole tibial lateral anatomical axis (0.15 degree in average; anterior slope 3.95- posterior slope 5.57 degree). This difference was smallest among that of the measured angle by the other reference lines (p < 0.001). Conclusion: The anterior cortical line of the proximal tibia appears to be the most reliable reference line for measuring the posterior slope angle on a knee lateral radiograph after TKA.
골육종조직에서 활성화된 Neutral RNase Isozyme의 정제와 작용기전에 관한 연구

Of the RNase isozymes isolated from osteosarcoma tissue of human, ribonuclease(RNase) isozyme I exhibited the highest activity and appeared to be activated. The present study was carried out to purify the RNase isozyme I and to determine the substrate specificity for the isozyme specfic to osteosarcoma. Activities of both RNase and RNase inhibitor in osteosarcoma tissue were markedly increased, indicating the possible use of the enzyme and the enzyme inhibitor as biochemical marker for osteosarcoma. RNases in osteosarcoma tissue were separated by a DEAE-cellulose column chromatography into five isozymes, of which two isozymes were activated and other two isozymes were specific to osteosarcoma. The activity of RNase inhibitor complexed with these RNase isozymes was observed to be high. Of the two RNase isozymes activated, RNase isozyme I exhibited higher activity and appeared to be specific to osteosarcoma. The RNase isozyme I was separated by a HPLC into 7 subpeaks, of which RNase isozyme I-3 with the highest RNase activity appeared to by specific to osteosarcoma. The RNase isozyme I-3 separated and purified from osteosarcoma tissue was not active against double stranded polynucleotides, but active against single stranded polyribonucleotide, being highly active against single stranded polyribonucleotide, being highly active on C-C, C-U and A-U linkages. A considerable activity was observed with RNA as substrate, being different from other RNase isozymes isolated from osteosarcoma tissue and its control bone tissue. The results obtained in the present study indicated that the RNase isozyme I-3 results obtained in the present study indicated that the RNase isozyme I-3 purified from osteosarcoma tissue was activated, specific to osteosarcoma and exhibited a considerable acitivty on RNA, suggesting that the isozyme play an important role in RNA mediated tumorigenesis in osteosarcoma.
