In order to assess the stability of the fracture, weight-bearing inducible displacements of the fracture fragments and their migration over a one-year period were measured by differentially loaded radiostereometric analysis and standard radiostereometric analysis, respectively. The mean inducible craniocaudal fracture fragment displacements measured -0.30 mm (-0.73 to 0.02) at two weeks and 0.00 mm (-0.12 to 0.15) at 52 weeks. All inducible displacements were elastic in nature under all loads at each examination during follow-up. At one year, the mean craniocaudal migration of the fracture fragments was -0.34 mm (-1.64 to 1.51). Using radiostereometric methods, this case series has shown that in the Schatzker type II fractures investigated, internal fixation with subchondral screws and a buttress plate provided adequate stability to allow immediate post-operative partial weight-bearing, without harmful consequences.enCopyright © 2011 by British Editorial Society of Bone and Joint SurgeryHumansTibial FracturesTomography, X-Ray ComputedTreatment OutcomeFracture Fixation, InternalBone PlatesBone ScrewsWeight-BearingRotationAdultMiddle AgedFemaleMaleJournal article002010875610.1302/0301-620X.93B6.261220002907149000192-s2.0-7995629818929676Solomon, L.
