Abstract EN
Over the last decade, the number of short stem total hip arthroplasty procedures has increased.
Along with the possible benefits associated with short stems is a smaller implant-bone contact surface, which may have a negative influence on primary stability and impair osseointegration.
Previous studies observed migration of short stems, especially within the first three months.
The variables that influence migration in short stem hip implants remain unknown.
Therefore, the purpose of this study was to associate the migration of short stems with its possible influencing variables.
Migration data from two different short stem studies were retrospectively analyzed.
Migration within the first two postoperative years was determined by model-based Roentgen stereophotogrammetric analysis.
Migration was correlated to bearing couple, type and size of stem, size of acetabular cup, and age, gender, weight, and height of patients using a multiple factor analysis.
Eigenvalue analysis explained 80.7% of the overall variance for the first three dimensions.
The four most dominant variables in the first dimension were weight, stem size, acetabular cup size, and patient height (correlations of 0.81, 0.80, 0.71, and 0.70, resp.).
None of the analyzed parameters (bearing couple, type and size of stem, size of acetabular cup, and age, gender, weight, and height of patients) affected the migration pattern of short stem THA with primary metaphyseal fixation.
