Statistical comparison of the posterior horizontal dislocation distances*
Design type | Hemispheric fixed bearing | Subhemispheric dual mobility | Modular dual mobility |
---|---|---|---|
Subhemispheric dual mobility | p = 0.474; R2 = 0.182; 95% CI, −1.231 to 2.081 | N/A | |
Modular Dual Mobility (MDM™) | p < 0.001; R2 = 0.985; 95% CI, 4.65–7.35 | p < 0.001; R2 = 0.998; 95% CI, 5.118–6.032 | N/A |
Anatomic Dual Mobility (ADM™) | p < 0.001; R2 = 0.999; 95% CI, 8.204–9.996 | p< 0.001; R2 = 0.998; 95% CI, −10.31 to −7.959 | p = 0.005; R2 = 0.98; 95% CI, 2.417–4.5 |
