髋关节发育不良：髋臼周围截骨术治疗症状性轻度髋关节发育不良的并发症和患者短期随访疗效髋关节发育不良：髋臼周围截骨术治疗症状性轻度髋关节发育不良的并发症和患者短期随访疗效作者：CenterforHipPainandPreservation,HospitalforSpecialSurgery,NewYork-USA.作者单位:BenjaminFRicciardi,KaraGFields,CatherineWentzel,DanyalHNawabi,BryanTKelly,ErnestLSink.译者：陶可（北京大学人民医院骨关节科）摘要简介：我们研究的目的是确定因轻度髋臼发育不良而接受髋臼周围截骨术(PAO)治疗的患者的并发症和早期功能结果评分。方法：研究人群由来自单中心前瞻性髋关节登记处、接受PAO的轻度髋关节发育不良患者（LCEA≥18°和≤25°；n=27名患者；轻度髋关节发育不良组）。接受PAO且患有更严重髋关节发育不良的患者的对照组（外侧中心边缘角[LCEA]≤17°；n=50名患者；严重发育不良组）被纳入作为对照组。术后6个月、1年和2年（平均15个月[范围6-30月]）记录人口统计学、影像学结果、并发症和功能结果评分。结果：接受PAO的轻度髋关节发育不良患者与更严重的髋关节发育不良患者的人口统计学特征相似。两组之间的放射学矫正效果和并发症发生率没有差异。功能结果评分显示，两组中的改良Harris髋关节评分(mHHS)、髋关节结果评分(HOS)日常生活活动(ADL)、HOS运动和国际髋关节结果工具33(iHOT-33)在所有时间点都有相似的改善。同时，超过90%的轻度髋关节发育不良患者在最终随访时的功能结果评分达到了最小重要变化(MIC)。讨论：接受PAO治疗的有症状的轻度髋关节发育不良患者与一组患有更严重髋关节发育不良的患者具有相似的并发症发生率和功能结果。??Complicationsandshort-termpatientoutcomesofperiacetabularosteotomyforsymptomaticmildhipdysplasiaAbstractIntroduction:Thepurposeofourstudyistoidentifycomplicationsandearlyfunctionaloutcomescoresinpatientstreatedwithperiacetabularosteotomy(PAO)formildacetabulardysplasia.Methods:ThestudypopulationconsistedofpatientsfromasinglecentreprospectivehipregistryundergoingPAOwithmildacetabulardysplasia(LCEA≥18°and≤25°;n=27patients;MildDysplasiagroup).AcomparisongroupofpatientsundergoingPAOwithmoresevereacetabulardysplasia(lateralcentre-edgeangle[LCEA]≤17°;n=50patients;SevereDysplasiagroup)wereincludedasacomparisoncohort.Demographics,radiographicfindings,complications,andfunctionaloutcomescoreswererecordedat6months,1year,and2yearspostoperatively(mean15months[range6-30]).Results:DemographiccharacteristicsweresimilarinpatientswithmilddysplasiaundergoingPAOcomparedwithmoreseveredysplasia.Achievementofradiologicalcorrectionandcomplicationrateswerenotdifferentbetweenthe2groups.FunctionaloutcomescoresshowedsimilarimprovementsinmodifiedHarrisHipScore(mHHS),hipoutcomescore(HOS)activitiesofdailyliving(ADL),HOSSport,andtheinternationalHipOutcomeTool-33(iHOT-33)atalltimepointsbetweenthe2groupswithover90%ofpatientsinthemilddysplasiagroupachievingaminimumimportantchange(MIC)infunctionaloutcomescoresatfinalfollow-up.Discussion:PatientswithsymptomaticmildacetabulardysplasiaundergoingPAOhavesimilarcomplicationratesandfunctionaloutcomesasacohortofpatientswithmoreseveredysplasia.文献出处：BenjaminFRicciardi,KaraGFields,CatherineWentzel,DanyalHNawabi,BryanTKelly,ErnestLSink.Complicationsandshort-termpatientoutcomesofperiacetabularosteotomyforsymptomaticmildhipdysplasia.ComparativeStudyHipInt.2017Feb21;27(1):42-48.doi:10.5301/hipint.5000420.陶可医生的科普号
