Table 1.
Demographic characteristics of each group of patients according to the implanted stem (Corail, Meije, Targos).
Fig 1.
The three stems used during this study.
a. Corail Depuy; b. Meije Tornier; c. Targos Lepine. The design includes a fully hydroxyapatite coating non-porous forged titanium alloy stem, with a proximal trapezoidal/quadrangular cross-section and a tapered distal stem. All stems had a collar.
Fig 2.
The three broach handles used in this study with lateral and superior views.
(a. Corail Depuy; b. Meije Tornier; c. Targos Lepine). All had a double offset with the same curve, allowing a femoral preparation in a satisfying axis, even with difficult exposures.
Fig 3.
The three broaches used for the preparation femoral in this study.
(a. Corail Depuy; b. Meije Tornier; c. Targos Lepine). The broach for the Targos stem presents a rounded back, in the continuity of the handle. The broaches for the Corail and Meije stems have a shoulder more or less marked, just before the handle.

Comparison of the mean varus and of the proportion of stems with a varus superior to 3°, between the three stems (Corail, Meije, Targos).

Postoperative pelvic AP views of three stems used in this study.
a. Right THA with a Corail stem (varus of 4.3°). b. Right THA with a Meije stem (varus of 4°). c. Right THA with a Targos stem (only Targos stem with a varus positioning of 3.1°).
