在股骨远端上，绘制股骨髁后部的切线（蓝线；选择髁更突出的切片）。两条线之间的角度代表股骨扭转角度。尽管其中一些参考点位于不同的相邻切片上，但现代工作站应该允许在1系列中的多个图像上绘制和修改一条线，或者，可以借助后处理软件将不同的切片叠加在单个图像上。Fig.8.PostoperativeAPpelvisplainradiographfollowingPAO(Periacetabularosteotomy)oflefthipin20-year-oldwomanwithanLCEAof34°(left)andaTonnisangleof3°?(right).图8.?20岁女性左髋PAO（髋臼周围截骨术）术后前后位(AP)骨盆X线片，LCEA为34°（左），Tonnis角为3°（右）。?HipDysplasiaAbstractAcetabulardysplasiarepresentsastructuralpathomorphologyassociatedwithhippain,instability,andosteoarthritis.Thewidespectrumofdysplasiaanatomicallyreferstoa3-dimensionalvolumetric-andsurfacearea-basedinsufficiencyincoverageandisclassifiedbasedonthemagnitudeandlocationofundercoverage.Borderlinedysplasiahasbeenvariablydefinedandleadstomanagementchallenges.Insymptomaticdysplasia,treatmentaddressescoveragewithperiacetabularosteotomy.Concomitantsimultaneousorstagedhiparthroscopyhassignificantadvantagestoaddressintra-articularpathology.Innonarthriticindividuals,thereisevidencePAOaltersthenaturalhistoryofdysplasiaanddecreasestheriskofhiparthritisandtotalhiparthroplasty.CLINICSCAREPOINTSAcetabulardysplasiaisacomplexmultiplanarstructuralpathomorphologyassociatedwithhippain,instability,andosteoarthritis.Thenaturalhistoryofdysplasialeadstochondralinjurysecondarytothehighlycomplex3-dimensionalvolumetric-andsurfacearea-basedinsufficiencyincoverage.Dysplasiacanbecharacterizedbyitslocation:anterior,posterior,orlateral(orglobal).EvaluationofdysplasiarequiresplainradiographsandeitherMRIorCTscan(orboth)toproperlymeasurecoverageandversion.Isolatedarthroscopyshouldnotbeusedtotreatstructuralinstabilityobservedinmoderateorseveredysplasia.Inproperlyselectedpatientswithtransitionalacetabularcoverage,orborderlinedysplasia,goodoutcomescanbeachievedatshort-andmid-termfollow-up.PAOandhiparthroscopycanbeusedtogether,eithersimultaneousorstaged,toaccuratelycorrectbothdysplasiaandFAIsyndrome.Innonarthriticindividuals,PAOaltersthenaturalhistoryofdysplasiaandreducestheriskofhiparthritisandsubsequentTHA.文献出处：JoshuaDHarris,BrianDLewis,KwanJPark.HipDysplasia.ReviewClinSportsMed.2021Apr;40(2):271-288.?陶可医生的科普号
