髖臼發(fā)育不良：美國臨床運動醫(yī)學雜志2021年研究進展髖臼發(fā)育不良：美國臨床運動醫(yī)學雜志2021年研究進展作者：JoshuaDHarris,BrianDLewis,KwanJPark作者單位:TheHoustonMethodistHipPreservationProgram,HoustonMethodistOrthopedicsandSportsMedicine,6445MainStreet,Suite2500,Houston,TX77030,USA;HoustonMethodistAcademicInstitute;HoustonMethodistOrthopedics&SportsMedicine,Houston,TX,USA;WeillCornellMedicalCollege,NewYork,NY,USA;TexasA&MUniversity,CollegeStation,TX,USA.Electronicaddress:joshuaharrismd@gmail.com.譯者：陶可（北京大學人民醫(yī)院骨關(guān)節(jié)科）摘要髖臼發(fā)育不良代表與髖部疼痛、不穩(wěn)定和骨關(guān)節(jié)炎相關(guān)的結(jié)構(gòu)病理形態(tài)。廣泛的不典型增生在解剖學上是指基于3維體積和表面積的覆蓋不足，并根據(jù)覆蓋不足的程度和位置進行分類。臨界髖臼發(fā)育不良的定義各不相同，并導致治療方式的不統(tǒng)一。對于有癥狀的髖臼發(fā)育不良，治療采用髖臼周圍截骨術(shù)。同步或分期髖關(guān)節(jié)鏡檢查對于解決關(guān)節(jié)內(nèi)病理學具有顯著優(yōu)勢。在非髖關(guān)節(jié)骨關(guān)節(jié)炎個體中，有證據(jù)表明PAO可以改變髖臼發(fā)育不良的自然病史，并降低髖關(guān)節(jié)骨關(guān)節(jié)炎和全髖關(guān)節(jié)置換術(shù)的風險。診所診治要點①髖臼發(fā)育不良是一種復雜的多平面結(jié)構(gòu)病理形態(tài)，與髖部疼痛、不穩(wěn)定和髖關(guān)節(jié)骨關(guān)節(jié)炎緊密相關(guān)。②髖臼發(fā)育不良的自然病史導致繼發(fā)于高度復雜的基于3-維度體積和表面積的覆蓋范圍不足軟骨損傷。③髖臼發(fā)育不良可以通過其位置來表征定位：前部、后部或外側(cè)部（或整體）。④髖臼發(fā)育不良的評估需要X線片和MRI、CT掃描，以衡量正常的覆蓋范圍和角度。⑤單純髖關(guān)節(jié)鏡檢查不應(yīng)用于治療中度或嚴重髖臼發(fā)育不良所致的髖關(guān)節(jié)解剖結(jié)構(gòu)不穩(wěn)定。⑥在正確選擇的具有過渡性髖臼覆蓋或臨界髖臼發(fā)育不良的患者中，短期和中期的隨訪可以取得良好的效果。PAO和髖關(guān)節(jié)鏡檢查可以同時或分階段一起使用，以準確地糾正髖臼發(fā)育不良和FAI髖關(guān)節(jié)撞擊綜合征。⑦在非髖關(guān)節(jié)骨關(guān)節(jié)炎個體中，PAO改變了髖臼發(fā)育異常的自然病史并降低了以下風險：髖關(guān)節(jié)骨關(guān)節(jié)炎和隨后的THA全髖關(guān)節(jié)置換術(shù)。?Fig.1.Weight-bearingAPpelvisplainradiographwithfocusonlefthipin17-year-oldgirl(left)showinganLCEAof14.3°measuredtothelateralsourcil(middle)and24.6°measuredtothelateralacetabularbone(right).圖1.?17歲女孩的負重前后位(AP)骨盆X線片，左髖（左）；LCEA測量值為14.3°（中）；測量到髖臼骨性外側(cè)邊緣為24.6°（右）。Fig.2.(A)Weight-bearingAPpelvisplainradiographwithfocusonlefthipin19-year-oldwomanshowingaTonnisangleof10°.(B)Anupslopinglateralsourcil(asterisk).(C)Upslopinglateralsourcilinthesamepatientvisualizedon3-dimensionalcomputedtomographyscan;and(D)aFEARIndexof4.1°.圖2.?(A)19歲女性的負重前后位(AP)骨盆X線片，重點關(guān)注左髖，Tonnis角為10°。(B)向上傾斜的眉弓（星號）。(C)在3維計算機斷層掃描中顯示同一患者的向上傾斜的眉弓；(D)FEAR指數(shù)為4.1°。femoroepiphysealacetabularroof：股骨骨骺髖臼頂TheFEARindexhasvalueintheevaluationofhipinstability(femoralheadmigrationonconventionalplainradiographsorheadrecenteringonanAPabductionview)inpatientswithtransitionalacetabularcoverage.FEAR指數(shù)對于評估具有過渡性髖臼覆蓋的患者的髖關(guān)節(jié)不穩(wěn)定性（傳統(tǒng)X線片上的股骨頭移位或AP外展視圖上的股骨頭復位）具有價值。Fig.3.Falseprofileplainradiographofrighthipin21-year-oldwoman(left)showinganACEAof22°measuredtotheanteriorsourcil(middleimage)and37.9°measuredtotheanterioracetabularbone(right).圖3.?21歲女性右髖部的假斜位X線片（左）；ACEA測量到髖臼關(guān)節(jié)面前緣的角度為22°（中）；測量到髖臼前緣骨質(zhì)的角度為37.9°（右）。Fig.4.Weight-bearingAPpelvisplainradiographwithfocusonrighthipin24-year-oldmanshowingthemeasurementsneededtocalculatetheAWIandthePWI.Abest-fittingperfectcircleisdrawnaroundthefemoralhead.Alineisdrawnconnectingthefemoralneckcenterintersectingwiththeheadcenter.AWI=AW/r;PWI=PW/r.圖4.?24歲男性的負重前后位(AP)骨盆X線片，重點關(guān)注右髖，顯示計算AWI和PWI所需的測量值。在股骨頭周圍繪制一個最合適的完美圓。繪制一條連接股骨頸中心與股骨頭中心相交的線。AWI=AW/r；PWI=PW/r。PWI:theposteriorwallindex;AWI:anteriorwallindex.PWI：后壁指數(shù)；AWI：前壁指數(shù)。Fig.5.Weight-bearingAPpelvisplainradiographwithfocusonrighthipin31-year-oldmandemonstratingapositiveposteriorwallsign()andpositiveischialspinesign(#).圖5.?31歲男性的負重前后位(AP)骨盆X線片，重點關(guān)注右髖，后壁征()和坐骨棘征(#)陽性。Fig.6.Clock-facepositionsofversionmeasurements.This3-dimensionalmodeldepictsthe3differentlocationsweusedtomeasurefocalacetabularversion(1,2,and3o’clock).(FromTannenbaumEP,ZhangP,MarattJD,etal.AComputedTomographyStudyofGenderDifferencesinAcetabularVersionandMorphology:ImplicationsforFemoroacetabularImpingement.Arthroscopy2015;31:1247–54;withpermission.)圖6.?髖臼測量的鐘面位置。這個3維模型描繪了我們用來測量髖臼局部區(qū)域的3個不同位置視圖（1點、2點和3點鐘方向）。Fig.7.Assessmentoffemoraltorsiononcross-sectionalimaging.Onconsecutivestrictaxialimagesovertheproximalfemur,determinethefemoralheadcenter(FHC)(yellowcircleandyellowline).Definingthefemoralneckaxis(greenline)canbedonebyseveralmethods.Leemethod(redbar):AlineisdrawnonthefirstimageonwhichtheFHCcanbeconnectedwiththemostcephalicjunctionofthegreatertrochanterandthefemoralneck;Reikerasmethod(lightbluebar):AlineconnectingtheFHCwiththefemoralneckcenterisdrawnonanimagewheretheanteriorandposteriorcorticesrunparalleltoeachother;Jarretmethod(notshown):AlineisdrawnonasingleimagethatrunsfromtheFHCtroughthecenterofthefemoralneck;Tomczakmethod(darkbluebar):TheFHCisconnectedwiththecenterofthegreatertrochanteratthebaseofthefemoralneck;andMurphymethod(orangebar):TheFHCisconnectedwiththecenterofthebaseofthefemoralneckdirectlysuperiortothelessertrochanter.Then,overthedistalfemur,drawatangenttotheposterioraspectofthefemoralcondyles(blueline;choosingtheslicewherethecondylesaremoreprominent).Theanglebetweenbothlinesrepresentsthefemoraltorsion.Althoughsomeofthesereferencepointsarelocatedondifferentadjacentslices,modernworkstationsshouldallowdrawingandmodifyingalineacrossmultipleimagesin1seriesor,alternatively,differentslicescanbesuperimposedo
