Table 2 Comparison of the restoration of anatomical parameters between the CoreHip stem and a standard anatomical stem (Δ = difference between the contralateral, non-operated side and the same parameter on the operated side after total hip arthroplasty, LLD = leg length discrepancy). Mean ± standard deviation (minimum – maximum) is shown
From: Reconstruction of the anatomy of the hip in total hip arthroplasty with two different kinds of stems
CoreHIP | Anatomical stem | p-value (Mann-Whitney-U-Test) | |
|---|---|---|---|
Δ offset horizontal | 2.5 ± 2.8 mm (0 – 14 mm) | 5.4 ± 4.1 mm (0 – 17 mm) | p < 0.001 |
Δ femoral neck-shaft-angle | 1.7 ± 1.6 degrees (0 – 6.7 degrees) | 5.6 ± 3.4 degrees (0.2 – 17.1 degrees) | p < 0.001 |
Δ offset vertical | 4.1 ± 3.5 mm (0 - 15 mm) | 5.0 ± 3.8 mm (0 – 25 mm) | p = 0.024 |
Δ LLD | 4.0 ± 3.9 mm (0 - 15 mm) | 4.5 ± 3.8 mm (0 – 18 mm) | p = 0.10 |
