Tegner 점수는술전평균 6.7±0.9 이었으나최종추시에서 6.2±0.7로술전상태로회복되었으며 (p>0.05) 한편 3D-CT는일반방사선사진에비해시인성 55.6%, 분쇄정도 50%, 완전전위여부는 44.4% 에서향상된정확도를보였다. 결론 : 급성후방십자인대경골부견열손상에서후내측도달법을통해골편크기에따라적절한수단의내고정을시행하여우수한임상적결과를얻었으며술전에시행한 3D-CT는골절양상을파악하고내고정방법을선택하는데유용하였다. 색인단어 : 후방십자인대, 경골부견열손상, 관혈적내고정, 3 차원전산화단층촬영 서론 후방십자인대의실질부단독손상이나견열골절은슬관절이굴곡된상태에서낙상이되거나자동차사고시 dashboard 에굴곡된경골이가격당하면서발생한다. 수술적치료의필요성에대해상반된의견이존재하는후방십자인대실질부의단독손상에비해후방십자인대경골의견열골절은인대가부착된골편을해부학적으로정복하여인대의길이를회복하고견고한고정 접수일 2010 년 5 월 30 일게재확정일 2011 년 1 월 31 일교신저자이주홍전북전주시덕진구금암동 , 전북대학교병원정형외과 TEL , FAX jhlee55@chonbuk.ac.kr 을통한조기관절운동을위해조기에견열된골편을고정하는것이일반적이다. 1-3) 경골부견열골절의수술적치료에는관혈적정복술과관절경적봉합술식이있다. 1945년 Abbot 가슬와부에대한직접도달법을기술한이래 Trickey 4) 가후방도달법을이용한관혈적정복술을처음소개하였고 Burks 와 Schaffer 5) 가기존의후방도달법의신경혈관손상문제를해결하기위해보다간편한접근법을제시한바있다. 한편관절경술기의발달로다양한형태의관절경적봉합술식들이발표되고있다. 6-10) 견열된골편고정에는봉합사, 금속나사, 생체흡수성나사등다양한고정방법들이사용되나 11-13) 견열골절의빈도가낮아고정방법들간의비교연구는드물며특히후방십자인대견열골절은동반손상이흔히존재하여일반방사선사진에서간과하기쉽고 14) 골편의크기, 분쇄정도및전위를평가하기어려워술전 대한정형외과학회지 : 제 46권제 3호 2011 Copyright 2011 by The Korean Orthopaedic Association This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License ( which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.

Kim 등 7) 은골절편이작을경우 (<10 mm) 다발성봉합사고정, 중간크기일경우 (10-20 mm) 다발성핀고정, 골절편이클경우 (>20 mm) 금속나사고정을시행할것을제시하였으며 Berg 등 19) 은골절편의크기가금속나사직경의 3배이상되어야효과적인고정이가능하다하였다. 저자들은 3D-CT 상골편의크기와분쇄정도를파악하고수술시야에서내고정방법을선택하였다. 술후임상적평가및 Telos를이용한부하검사에서고정방법간의차이는없었고전예에서수상이전의활동수준으로복귀가가능하였다. 이는기존의결과와유사하며인대실질부손상과달리조기에적극적인수술적내고정으로일관되게우수한임상적결과를보였다. 그러나후방도달법을통한고정술은동반된슬관절내손상이있으면체위변경없이동시에치료하기가어려우며불가피하게근육이나후방관절막을광범위하게노출시켜야하는제한점이 있어 K-강선, staples, 금속나사, 봉합사와같은여러기기들을이용한관절경적고정을통해좋은결과가보고되고있다. 6-8,10,20,21) 그러나관절경적정복술은술기습득이어렵고신경혈관손상이잠재되어있으며경골고평부까지침범한큰크기의골편이면관절경적정복이용이치못해적응증이되지못한다. 10) 또한후방십자인대경골견열골절은수상기전상슬관절주위로심한연부조직손상이동반되는경우가흔하여관절경의관절내시야확보가어려울수있고구획증후군의위험도가존재한다. 또한 Shino 등 9) 이후방십자인대경골부견열골절에대해삽입한금속나사가후방십자인대실질부를자극하여굴곡시통증을유발시킬수있어치유후에금속나사의제거가필요하기도하므로용이한나사못제거를위해서는전방에서후방으로의나사못고정을제안하였으나전방에서후방으로의금속나사고정은견고한압박고정을얻기가어려우며금속나사의삽입동안에골절간격을신연시킴으로써불유합이발생될수있다. 22) 저자들의경우에는관혈적내고정후고정물에의해굴곡시통증을유발하여내고정의제거가필요한경우는없었다. 저자들의연구는후향적이며내고정방법에따른비교가가능할정도의많은증례가아니어서내고정선택기준의일반화을제시할수없다. 그러나동반손상없이단독으로후방십자인대경골부견열골절이존재하는빈도가적어전향적연구를시행하기는어려우나인대손상이면서일종의골손상이므로짧은추시기간에도우수한결과를얻을수있었으며다양한형태의견열골절에도관혈적접근을통해여러내고정방법을이용한내고정이항상가능하여정상수준의후방안정성을회복할수있었다. 결론 급성후방십자인대경골부견열손상에서안전한후내측관혈적도달법을통해골편크기에따라적절한수단의내고정을시행하여우수한임상적결과를얻었으며술전에시행한 3D-CT 는골절양상을정확히파악하고내고정방법을선택하는데유용하였다. 참고문헌 1.

6 236 박종혁 왕성일 이주홍외 1 인 Open Repair of Acute Tibial Avulsion Injury of Posterior Cruciate Ligament - Clinical Outcomes and Usefulness of Preoperative 3-D CT - Jong-Hyuk Park, M.D., Sung-Il Wang, M.D., Ju-Hong Lee, M.D., and Hee Rack Choi, M.D. Department of Orthopedic Surgery, Chonbuk National University Medical School, Jeonju, Korea Purpose: To evaluate the clinical outcome of open repair of acute tibial posterior cruciate ligament (PCL) tibial avulsion injury using the posteromedial approach, and to examine the usefulness of pre-operative 3D-computed tomography (CT) imaging. Materials and Methods: From July 2004 onwards, among the 33 patients with acute tibial avulsion injury of the PCL, 22 patients were available for a 1-year follow-up. Patients underwent internal fixation using screws, pullout sutures or staples through the posteromedial approach. Clinical evaluations were performed using the posterior drawer test, posterior drawer stress x-ray, range of motion and Tegner score. In addition, size of the fragment, visibility, comminution, displacement and presence of extension were studied and were compared to the pre-operative X-ray and 3D-CT imaging. Results: Four cases demonstrated 10-degree restriction in flexion and 1 case demonstrated 10-degree restriction in extension compared to the unaffected side. Except for the 2 cases which had Grade I posterior instability on the posterior drawer test, the results of the post-operative joint stability were negative and the posterior drawer stress X-ray using the Telos device showed an average of 0.57±0.4 mm. Like the average pre-operative Tegner score of 6.7±0.9, the Tegner score was restored to 6.2±0.7 (p>0.05) at the last follow-up. 3D-CT showed an improved accuracy in visibility (55.6%), comminution (50%) and displacement (44.4%) compared to the simple X-ray. Conclusion: The acute tibial avulsion injury treated with the appropriate internal fixation through the posteromedial approach based on the fracture size demonstrated exellent outcomes. The pre-operative 3D-CT was useful for identifying the fracture pattern and choosing the appropriate internal fixation.
