This cumulative long-term risk of dislocation has been highlighted in other recent studies (von Knoch et al. 2002, Berry et al. 2004).
Short-term dislocation and long-term damage would be inevitable consequences.
Simple inversion rarely produces dislocation with long-term morbidity, while more violent injuries, e.g., those incurred in motor vehicle accidents or after a fall from height, are more likely associated with persistent symptoms [14].
As medium- to long-term outcome parameters, we selected: dislocation, septic loosening, aseptic loosening, and subjective outcome at follow-up.
Alas, what should be short-term dislocations now are long-term.
As stated in "Earthquake cycle model with dislocations" section, long-term displacement is not dependent on the interseismic process, so Fig. 4b is the same as Fig. 3b, showing the displacement accumulation rate of ~0.08 mm/year on land.
The concomitant reduction in dislocation curvature density decreases the elongation (source) term vq in the evolution equation of the total dislocation density (10) – an effect which has an important long-term impact on the evolution of the dislocation microstructure and may outweigh the direct effect of annihilation.
However, the rationale for our study was that presumably the reason for using alternative bearings in Medicare patients is to reduce short-term complication rates (eg, dislocation), rather than long-term complications (eg, wear/osteolysis), which are more of a concern in younger patients than in Medicare patients.
Surgery with a temporary fixation for acute grade-V AC joint dislocation leads to successful long-term functional results.
Statements about potential long-term changes, such as for example, SCJ dislocation are not possible, because of our short-term follow-up with a mean of 29 months.
