Surgical indications have been increasing recently. Moreover, additional surgical techniques allow both the anatomy and function to return to its normal state. Recently, the concepts and treatments for extra-articular pathologies, such as deep gluteal syndrome, ischiofemoral impingement, subspinal impingement and iliopsoas impingement as well as classic indication, such as femoroacetabular impingement, acetabular labral tear, loose bodies, and synovial osteochondromatosis have been introduced. We present a diagnosis and treatment for diverse indications of hip arthroscopy, preoperative considerations, surgical technique and postoperative rehabilitation. Key words: hip, arthroscopy, indication, diagnosis, therapeutics 서론 정형외과분야에서관절경의적용은광범위하게이루어지고있 다. 깊게위치한고관절의위치, 관절주위의복잡한신경 혈관 구조, 관절경기구를운용하기에좁은관절간격등의해부학적 이유로인해고관절질환의관절경적접근은슬관절, 견관절등 에비해상대적으로늦게시작되었으나설명되지않았던고관절 의증상이대퇴비구충돌 (femoroacetabular impingement, FI), 비 구순파열등의개념과함께관절경적치료에의해해결되면서 효과적인술식으로인식되었다. 최근에는기존의관절내병변뿐 아니라관절외병변, 스포츠관련손상까지그임상범위가확대 되고있다. 관절경을시행하는술자는고관절의관절내구조와 관절낭, 근육, 인대등의관절주위의연부조직에대한해부학적 접근, 수술전준비, 수술기법, 수술중발생할수있는상황대처, Received May 2, 2017 Revised ugust 27, 2017 ccepted September 7, 2017 Correspondence to: Deuk-Soo Hwang, M.D. Department of Orthopedic Surgery, Chungnam National University School of Medicine, 282 Munhwa-ro, Jung-gu, Daejeon 35015, Korea TEL: +82-42-338-2480 FX: +82-42-338-2482 E-mail: dshwang@cnu.ac.kr 술후재활에대한이해가있어야성공적인결과를얻을수있다. 저자들은고관절관절경에대한임상적경험에대해기술하고, 최신지견에대한문헌고찰을하고자한다. 고관절관절경의수술기법 1. 고관절관절경수술전진단진단의오류와부적절한환자의선택은수술후지속적통증의원인이되므로정확한진단은수술의결과를결정하는가장중요한요인이며, 술자는관절경적수술선택에확실한기준이있어야한다. 임상적양상에서고관절관절내병변을가진환자는쪼그리고앉을때나관절의움직임에의해발생되는서혜부통증을호소하며, 증상이악화되면서빈도가증가되고안정시에도통증을느끼게된다. 환자들은움직일때 무언가찌르는느낌 (sticking), 관절이잠기는느낌 (locking), 잡혀있는느낌 (catching), 걸리는느낌 (clicking) 등으로표현하며, 통증의위치를물을때손의모양을 C 자모양으로고관절부위를붙잡는 C 증후 (C sign) 를보이는데 (Fig. 1), 이부위는진성고관절부위 (true hip region) The Journal of the Korean Orthopaedic ssociation Volume 52 Number 6 2017 Copyright 2017 by The Korean Orthopaedic ssociation This is an Open ccess article distributed under the terms of the Creative Commons ttribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/4.0/) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.

Eriksson 등 6) 은견인을위해서 300-500 N의견인력이필요하다고하였으나, 마취기술의향상으로 110-440 N의범위에서도성공적으로관절경을시행할수있다. 그러나대부분의견인테이블은견인력측정기가없어저자들은통상적으로관절경의두께의 2-3배정도 (8-10 mm) 의간격을기준으로한다. 너무적은견인은의인성비구순및대퇴골관절연골손상 (scuffing) 을유발하며 (Fig. 5), 과도한견인은신경병변을유발할수있다. 적절하게견인되었을때고관절내음압경사가증가되어방사선투시기에서견인력을선형적으로증가시키는진공현상 (vacuum seal) 을관찰할수있다. 남자는여자에비해더많은견인력이필요하며, 특히강직성척추염이나골성변형이많아견인이되지않는환자들은변연구획 (peripheral compartment) 부터삽입구를제작해야하는수술적접근이필요하기때문에반드시수술소독을시행하기전에견인상태를확인해야한다. 앙와위의자세는고관절을신전, 25 외전또는중립으로고정하고발목의회전정도에따라삽입구의위치가변하게되는데, 관절내병변이비구의외측에위치하면발을내회전상태에서, 병변이비구의전방 / 내측에위치하면발의위치를외회전상태에서삽입구를제작해야접근이용이하다. 술자와보조자, 수술간호사는수술시행하는측에서게되며관절경모니터는술자반대편에위치하고방 Figure 4. Position and traction. 사선투시기는환자의다리사이로접근된다. Brumback 등 7) 은짧은시간동안 500 N의견인은안전하지만 700 N 이상의견인이 1 시간이상지속될경우신경마비가발생할수있다고하였다. 대부분의수술은 500 N 이하의견인력에서시행되므로수술보조자는수술시간이 2시간이상지속될경우술자에게이를통보해야하여 10-20분정도견인을풀고다시수술을시작하거나변연구획부터수술시행후다시견인하여중심구획의수술을시행해야한다. 2) 삽입구 (portals) 고관절관절경삽입구는 18개이상으로보고되고있으나대부분의저자들은 9개정도의삽입구만으로도고관절관절경을안전하게시행할수있다고하였다. 8) Byrd 등 9) 은고관절관절경의해부학적연구에서삽입구의위치와관절외구조의관계를조사하면서전방, 전외측, 후외측 3개의기본삽입구 (standard 3 portals) 를제시하였다. 저자들은앙와위에서변형된전방삽입구 (modified anterior portal), 전외측삽입구 (anterolateral portal), 후외측삽입구 (posterolateral portal) 를기본삽입구로수술을시행하고있으며필요에따라부삽입구 (accessory portal), 내측으로관절경적접근이필요할때내측삽입구 (medial portal) 를추가적으로사용한다 (Fig. 6). (1) 변형된전방삽입구 : 대전자의전방과후방경계선의첨부의상부 1 cm의위치가각각전외측과후외측삽입구가되는데, 고식적전방삽입구 (classic anterior portal) 의위치는전외측삽입구에내측으로그은수평선과전상방장골극 (anterior superior iliac spine, SIS) 에서슬개골상극을향해원위부로그린선과만나는점으로 SIS에서평균 6.3 cm에위치한다. 변형된삽입구는고식적전방삽입구와전외측삽입구를한변으로하는정삼각형을원위부로그렸을때그려진역정삼각형의원위꼭지점의위치가되며비구순봉합시봉합나사의삽입각도를낮출수있어상대적으로안전한봉합을시행할수있다. 10) 전방관절낭을통과하기전에봉공근 (sartorius) 과대퇴직근 (rectus femoris) 을통과하며, 외측대퇴피부신경 (lateral femoral cutaneous nerve) 은전방삽입 FH FH L B Figure 5.

Fluoroscopic image of the medial portal. 구부위에서 3개이상의가지로나뉘게되어전방삽입구는이가지사이로지나가야한다. 외측대퇴회선동맥 (lateral femoral circumflex artery) 은보통전방삽입구의하부로 3.7 cm에위치하고있으나과도한출혈이생긴보고는없다. 전방삽입구를통해관찰이용이한구조물로는대퇴골의전방부, 외측비구순, 상방지대주름, 횡비구인대전방부및원형인대등이있다. (2) 전외측삽입구 : 전외측삽입구는중둔근 (gluteus medius) 을뚫고관절낭의외측을관통하며, 전외측삽입구를제작할때는상둔부신경 (superior gluteal nerve) 의손상을주의해야한다. 전외측삽입구는비구중심부에서하부를걸쳐비구의외측모서리의관찰이용이하며, 유리체가잘이동하는부위를포함해서비구후방부관찰도용이하다. 앙와위에서기준삽입구로주로이용된다. (3) 후외측삽입구 : 후외측삽입구는대부분의관절내병변이전방에존재하므로후외측삽입구를작업삽입구로이용하는경우는드물고보통관절액의배수로이용된다. 중둔근과소둔근을뚫고관절낭의후방변연부에서외측관절낭을통과하여이상근건의상부와전방부를지난다. 외측관절낭부위에좌골신경 (sciatic nerve) 이위치하므로후외측삽입구제작시에는견인테이블의위치를높이고끝이무딘 obturator로부드럽게삽입해야좌골신경손상을피할수있다. 삽입구제작시표면해부학을통해대전자의전방과후방경계를펜을이용하여방사선투사기에서의대전자첨부전방과후방의근위 1 cm 지점이각각전외측삽입구와후외측삽입구의바늘삽입위치가된다. SIS에서슬개골의상극을향해선을그리는데이는대퇴혈관과신경과의경계선으로이용된다. 방사선투시기하에서변형된전방삽입구위치에 16게이지척추천자바늘을 15-25 의경사로관절강을향하여진입하면고관절관절낭과접촉을느낄수있으며, 이때저항이있으면비구나비구순과의접촉을의미하기때문에약간원위부로바늘을이동시켜부드러운진입을느끼면서관절낭과천자를시행한다. 이때척추천 자바늘의속침 (stylet) 을빼면일부공기가관절내로유입되면서방사선투시기에서공기관절사진 (air arthrogram) 을확인할수있다. 공기관절사진이보이지않는경우척추바늘의속침을빼고가이드와이어를척추천자바늘을통해진입시켰을때, 관절내로들어간경우는가이드와이어가반대측비구벽에접촉되어방사선투사기상에서휘어지는것을확인할수있다. 척추천자바늘을통해가이드와이어를삽입한후척추천자바늘을제거하고가이드와이어주변으로 1 cm 정도피부절개를한다음 obturator를통과시켜전외측삽입구를제작한후관절경을삽입하여관절내병변을확인한다 (Fig. 7). 방사선투시기와관절경하에서척추천자바늘을관절경의끝을맞춰진입시키게되는데통상적으로두부측, 후방으로 30-40 의각도로삽입할때관절내로들어가게된다. 관절경하에서척추천자바늘이관절강안으로안전하게삽입되면 obturator를이용하여변형된전방삽입구를제작한다. 전외측삽입구를맹검상태에서제작할경우, 의인성비구순또는대퇴골관절연골손상을유발할수있으므로맹검삽입구의삽입은후외측삽입구가유용하다. 관절견인시전방관절보다후방관절낭의면적이넓으며전방비구순보다후방비구순의길이가짧아상대적으로의인성손상이적다. 안전한삽입구제작을위해저자들의삽입구제작방법을소개하면, 방사선투시기하에서전외측삽입구에척추천자바늘을관절낭에접촉할때까지만진입시킨후관절낭만을살짝천자한상태로놓고, 맹검삽입구를후외측삽입구로척추천자바늘을두부측 5-10, 전방측 5-10 각도로진입시킨다. 그후첫번째관찰삽입구인후외측삽입구를제작한후관절경감시하에서전외측삽입구를제작한다음관절경을전외측삽입구로옮겨관절경감시하에서전방삽입구를제작한다. 이방법은관절경을후외측-전외측-전방삽입구순서대로이동시켜중심구획의구조물의손상을주지않고안전하게삽입구를제작할수있는장점이있다. 대부분의술자들은견인후중심구획의관절병변을회복한후변연구획을치료하는방법을이용하나일부술자는견인없이수술하는방법을보고하고있다. 관절내구조물은견인장치를이용해야하나대퇴골두의비체중부하관절연골, 대퇴경부의병변및내측및전측활액막주름 (medial and anterior synovial fold), 고관절윤대 (zona orbicularis) 관절의변연구획은견인장치없이도수술이가능하다. Dienst와 Kohn 11) 은일차적으로변연구획을통한수술적접근을시행하며변연구획의해부학적구조의정확한판단및대퇴골성형술의골절제가용이하다고하였다. 또한통상적으로비견인방법이전에견인방법을먼저숙지하는것이좋다고하였는데, 이는견인방법이환자의체위에더욱의존적이기때문이라고하였다. 견인을시도하였으나관절간격을얻을수없는환자는불가피하게변연구획수술후중심구획으로이어지는술식을선택해야한다. 변연구획의관절경적술

Philippon 등 18) 은비구순의기능중 fluid seal 효과를강조하면서사체연구를통해비구순부분 / 완전절제후관절내압력은각각평균 53%, 24% 인반면, 비구순봉합술이시행된고관절에서는환형봉합이시행된후평균관절내압력이 70% 이고, 기저부봉합술이시행된고관절의평균관절내압력은 134% 로기저부봉합이우월하다고했다. 그러나 Jackson 등 19) 은두봉합법의비교연구에서 2년추시에서임상적결과의유의한차이가없다고하였다. 또한고관절에서의비구순재건술 (labral reconstruction) 에대해보고되고있는데, Philippon 등 18) 의사체연구에서비구순재건술후관절내압력은 110% 로정도로우수한결과를보인다고하였고, 18) Chahla 등 20) 도비구순이결손된고관절에서비구순의재건은정상고관절과같은관절내압력상태로회복시킬수있다고하였다. 저자들도비구순이결손된고관절관절경재수술에서비구순재건으로좋은임상결과를얻었으나재건술의결과에대해서는장기적추시결과를요한다 (Fig. 10). 비구순봉합술이끝나면탐침자를이용하여봉합상태를확인한후관절경을관절내심부로진입시켜비구관절연골의상태를확인한다. Beck의분류에따르면비구관절연골손상은연골연화 (chondromalasia), 비구에서의연골분리 (debonding), 균열 (cleavage), 연골분리 (detached cartilage) 로분류할수있다. 21) 연골연화증이나연골분리는비구순을비구에서분리하지않고열퇴축술또는비구순봉합시연골봉합을동시에시행하는데, 15) 이때연골을비구에부착시키기위해 fibrin glue 등을삽입하기도 Figure 9.

Marquez-Lara 등 23) 은고관절관절연골손상의체계적문헌고찰에서관절연골의변연절제 (debridement), 미세천공술, 자가연골세포이식 (autologous chondrocyte transplantation) 모두고도의관절연골손상에서단 중기추시시동등한임상호전을보였고, 손상부위와크기가술후결과에영향을주는요인이라고하였다. 관절경을비구와 (acetabular fossa) 에근접시키면원형인대를관찰할수있게되는데파열이있을경우수술적적응이될수있다. 원형인대는고정된발목을내회전, 외회전할때원형인대의움직임을확인할수있으며 (Fig. 11), 굴곡형고주파절제기를이용하여부분절제한다. 파열은보이지않으나전체적부종이있는경우는가열수축술 (thermal shrinkage) 를시행한다. de S 등 24) 은원형인대의부분파열이있을경우관절경적부분절제술이단기적임상증상을호전시키나고관절의불안정성이있는원형인대완전파열은자가, 동종, 합성인대를이용한재건술이필요하다고하였다. 2) 변연구획 (peripheral compartment) 중심구획의술식이끝나면견인을풀고비구순과대퇴골두-경부접합부와접촉을확인하는데통상적으로전외측삽입구가관찰삽입구로이용되고전방삽입구가작업삽입구로이용된다. 변연구획으로이동시에시야확보가어려운데, 견인을풀기전에전방삽입구에교환막대 (switching stick) 를넣고절개된관절낭의원위부로밀면서견인을풀어시야를확보한후 shaver와고주파절제기를이용하여관절낭을마름질하여관절경의해부학적구조를지속적으로인지해야한다. 수술보조자로하여금고관절을 45-60 정도굴곡시키면, 고관관절의대퇴골두-경부접합부가관절경시야로들어오게된다. 시야가적절하지않을경우관절낭절개를대퇴골경부부위로확장하는데, 고관절윤대를침범하지않도록해야한다. 고관절불안정성이있거나관절낭절개가큰경우모든술식후관절낭봉합술을시행한다. 전외측삽입구를통해대퇴골두-경부접합부의골성융기 (bump) 를확인하고, 수술보조자로하여금고관절의굴곡, 내회전, 외회전하여대퇴골과비구순의접합상태를확인하게하며, 전방삽입구를통해고주파절제기를이용하여대퇴골성형술의경계를표시한다. 관절경적절삭기를이용하여근위부에서원위부로골절

493 The Current Concepts of Hip rthroscopy 고관절관절경고식적적응증과확대된적응증 저자에따라의견이분분하나일반적적응증과금기증은다음과 같다 (Table 1). 고관절관절경의수술적선택에있어유병기간이 가장중요하다. 저자들은유병기간이 6 개월이상경과된경우나 비스테로이드성소염진통제, 물리치료등의보존적치료를시행 한후에도 2 개월이상증상이지속되는경우, 보존적치료에도증 상의변화가전혀없거나조절되지않는통증이있을경우수술 적응으로판단한다. 고관절주위의여러질환들이소개되면서수 술적적응도확대되고있다. 이에저자들은고관절관절외병변 중보존적치료에실패할때수술적치료가시도되는질환에대 해기술하고자한다. 1. 심부둔부증후군 (deep gluteal syndrome) 고관절후방부의해부학과좌골신경에대한이해가발달되면서 이상근증후군 (piriformis syndrome) 외에둔부하공간 (subgluteal space) 여러부위에서의좌골신경압박에의한병변을심부둔부 증후군이라는용어로사용하게되었다. 25) 좌골신경은과굴곡, 외 전, 외회전동작에서대전자후방경계부부위로미끄러져들어가며, 반양막근 (semimembransus muscle) 의부착부와대전자의후방경계와만나게된다. 좌골신경의주행은슬관절의굴곡 신전에의하며무릎이굴곡되었을때는후외측으로, 무릎이신전되었을때는후방심부공간으로들어간다. 슬관절이신전된 SLR test에서좌골신경은고관절내측으로 28 mm 정도주행하게되는데심부둔부공간에서이러한주행에영향을주게되면신경병변이발생할수있다. 26) 가장흔한증상은엉덩이통증과대전자부후방부의압통과좌골신경통유사병변으로특징적인증상이없어관절내, 관절외증상, 척추방사통과감별해야한다. 능동적이상근검사 (active piriformis test) 는환자를측와위로위치시키고검사자가환자의뒤꿈치를민상태에서환자에게고관절을능동적외전, 외회전하도록하고검사자는저항을주면서이상근을촉지할때압통을느끼는경우를양성으로판정한다. 좌식이상근신장검사 (seated piriformis stretch test) 는환자가앉아있는상태에서무릎을펴고관절을수동적내전, 내회전시킬때후방둔부공간에서통증의유무를확인하는검사이다. 이두가지검사에서양성을보이는경우내시경적좌골신경포착의민감도와특이도를각각 91%, 80% 로보고하고있다. 27) 심부둔부증후군은 Table 1.

494 Pil-Sung Kim and Deuk-Soo Hwang 생활습관변경, 물리치료, 비스테로이드성소염제를이용한보존적치료및국소마취제나스테로이드병변내주사를통해증상을경감시킬수있으나이러한치료에증상이호전되지않는경우개방또는내시경적수술적치료를고려할수있다. 여러연구에서개방후좌골신경감압후개선된임상결과를보고하였으며, 28,29) Dezawa 등 30) 이처음으로내시경적좌골신경감압을시도한이래 Martin 등 31) 은 35예의심부둔부증후군의내시경적치료에대해보고하였고, Hwang 등 32) 은좌골신경주위낭종에대한감압과이상근주위유착을제거하는관절경적감압술치료후호전된임상결과를보고하였다. 그러나성공적인내시경적치료를위해서는다수의임상적경험과좌골신경의해부학적구조를이해해야의인성좌골신경손상을피할수있다. 33) 2. 좌골대퇴충돌 (ischiofemoral impingement) 좌골대퇴충돌은 1977년에인공고관절전치환술후발생하는고관절의통증의원인으로처음보고되었다. 34) 좌골대퇴공간 (ischiofemoral space) 이라고불리는대퇴골소전자와좌골결절 (ischial tuberosity) 사이의공간에서대퇴사각근 (quadratus femoris) 의압박에의해통증이발생한다 (Fig. 13). 여성에서호발되며노화에따른근육손상, 35) 소전자에부착되는장요근, 좌골조면의슬건 (hamstring) 및윤활막염에의한압박, 36) 심부고, 34) 외반고 (coxa valga) 에서증가된대퇴골경간각, 37) Legg-Calve-Perthes 병, 38) 인공고관절전치환술후감소된대퇴 offset의주대를사용하거나비구컵의골반내측위치, 소전자를침범한전자주위골절, 34) 소전자주위의외골종 (exostoses) 35) 등이병인으로지목된다. 보존적치료또는 CT하대퇴사각근내국소마취제또는스테로이드주사가통증을완화시켜줄수있으며, 39) 다른질환에비해상대적으로낮은수술적응을보인다. Safran과 Ryu 40) 는좌골대퇴충돌로진단된환자의 5% 만이수술적적응이된다고하였고, 인공고관절전치환술후발생한좌골-대퇴충돌의개방성소전자절제는좌골-대퇴공간을넓힐수있으나술후고관절굴곡력감소와 35) 후방접근법을이용한고관절전치환술에서이술식이적용될때관절의불안정성을유발할수있어유의해야한다. 41) 보고된논문이상대적으로적지만몇몇저자들이많은수술적접근에대해발표하였고, 수술후합병증없이성공한예에대한보고도있다. 40,42) 3. 장골극하충돌 (subspinal impingement; anterior inferior iliac spine impingement) 장골극하충돌은비후된전하방장골극 (anterior inferior iliac spine, IIS) 과대퇴골경부원위부와의충돌로장골극과비구경계부사이에존재하는대퇴직근 (rectus femoris) 과비구순, 전방관절낭의손상이유발되고통증이발생하는현상을지칭한다. Hetsroni 등 43) 은 3D CT를이용하여극하충돌을 IIS의위치에따라비구경계근위부에존재하는경우를 I형, 비구경계선에위치하는경우를 II형, 비구경계원위부까지돌출되는경우를 III형으로분류하였다. II형과 III형은고관절굴곡과내회전의감소와관계되어있으며장골의 IIS의감압이필요하다. FI와비슷한증상을보이거나 FI 또는비구순파열이동반되어전방충돌검사에서양성을보이며, 고관절굴곡제한을보이기때문에 FI와 IIS 형태의방사선적평가가이루어져야한다. 44) 비수술적치료에대한효과는면밀히조사되지않은편이지만, 42) 기계적증상을보이는경우수술적치료가적용되어야한다. 관절경적장골의 IIS 감압술은공존하는관절내병변에대해관절경적치료후방사선투시기하에서 IIS의절제가시행되는데, 43) 여러연구에서술후스포츠활동으로의복귀와관절운동범위증가, Harris 고관절점수, 시각통증지수 (visual analogue scale) 통증점수의증가등의향상된 2년이상의단기추시결과를발표하였다. 43,45,46) F Figure 13.
