Background: Hemiarthroplasty of the shoulder is known to provide satisfactory long term results provided concentric reduction can be obtained in a high percentage of patients. Careful soft tissue balancing with appropriate adaptation of version of the component appears to allow good results permitting centering of the arthroplasty without replacement of a glenoid component.
Materials And Methods: 29 consecutive patients (30 shoulders) who underwent Oxford cementless shoulder hemiarthroplasty between 2004 and 2006 were analyzed.
Summary Of Background Data: The sagittal profile of lumbar endplates is discrepant from current simplified disc replacement and fusion device design. Endplate concavity is symmetrical in the coronal plane but shows considerable variability in the sagittal plane, which may lead to implant-endplate mismatch.
Objective: The aim of this investigation is to provide further analysis of the sagittal endplate morphology of the mid to lower lumbar spine study (L3–S1), thereby identifying the presence of common endplate shape patterns across these levels and providing morphological reference values complementing the findings of previous studies.
