The main measure measures after hemiarthroplasty is femoral hemiarthroplastyare:*'''Leg length discrepancy''' as in total arthroplasty above.*'''Femoral (neck) offset''', which is defined as the perpendicular distance between the intramedullary or longitudinal axis of the femur and the center of rotation of the native or prosthetic femoral head.<ref name="JonesBriffa2017"/> An offset of less than 33 mm is associated with hip dislocation.<ref name="NinhSethi2009">{{cite journal|last1=Ninh|first1=Christopher C.|last2=Sethi|first2=Anil|last3=Hatahet|first3=Mohammed|last4=Les|first4=Clifford|last5=Morandi|first5=Massimo|last6=Vaidya|first6=Rahul|title=Hip Dislocation After Modular Unipolar Hemiarthroplasty|journal=The Journal of Arthroplasty|volume=24|issue=5|year=2009|pages=768–774|issn=08835403|doi=10.1016/j.arth.2008.02.019}}</ref>
