Image-based navigation improves the positioning of the humeral component in total elbow arthroplasty.
HYPOTHESIS Implant alignment in total elbow arthroplasty (TEA) is a challenging and error-prone process using conventional techniques. Identification of the flexion-extension (FE) axis is further complicated for situations of bone loss. This study evaluated the accuracy of humeral component alignment in TEA. We hypothesized that an image-based navigation system would improve humeral component p...
متن کاملElbow dislocation with bicondylar humeral fracture in an adult: a unique type of injury
Simultaneous fracture of lateral condyle and medial epicondyle of humerus along with elbow dislocation is very rare injury in adults. Only a few cases have been reported in literature in pediatric age groups. The authors describe a case report of fracture of lateral condyle and medial epicondyle of humerus along with elbow dislocation in a young adult. The patient sustained injury in the form o...
متن کاملCombined Rotational Alignment Change after Total Knee Arthroplasty in Different Tibial Component Designs: Implications for Optimal Tibial Component Rotational Alignment
Purpose The rotational alignment of the femoral and tibial components is closely related to the results after total knee arthroplasty (TKA). In this study, we measured the combined rotational alignment change (ΔCR) after TKA and compared the different influence of symmetric and asymmetric tibial component designs on the combined rotational alignment. Materials and Methods Eighty-four patients...
متن کاملA clinical study of the rotational alignment of the femoral component in total knee arthroplasty
We describe here various surgical options to obtain a correct rotational alignment of femoral component in total knee arthroplasty (TKA). The correct rotational alignment is the key point to obtain a rectangular balanced flexion gap as well to have a good patellar tracking. For that reason, rotation alignment largely affects postoperative kinematic results particularly during flexion.
متن کاملA simple method for accurate rotational positioning of the femoral component in total knee arthroplasty
Background and purpose - There are many techniques for placing the femoral component in correct rotational alignment in total knee arthroplasty (TKA), but only a few have been tested against the supposed gold standard, rotation determined by postoperative computed tomography (CT). We evaluated the accuracy and variability of a new method, the clinical rotational axis (CRA) method, and assessed ...
