The Cenos hollow stem in total hip arthroplasty: first experiences in a prospective study.

Abstract:

:Due to its hollow construction, which gives it elasticity, the Cenos hollow stem (Artos) reduces stress shielding in the intertrochanteric region and reduces bone remodelling at the distal tip after implantation of a cementless stem in the femoral canal. This should contribute to a longer implant survival time and reduce the number of revision procedures required for implant loosening. Its anatomical shape means that it fits well in the femoral canal and additionally improves load distribution. We prospectively studied patients in whom the Cenos hollow stem was implanted in our clinic. The clinical results after 1 year and 40 implantations are very satisfactory. No thigh pain has been reported so far, which is probably due to the effectiveness of the increased elasticity and the better fit of the stem. Preoperative planning with a special template is very accurate, and in combination with the anatomical shape of the stem makes the surgical procedure easy. The relatively high number of ectopic ossifications found in our series is obviously not related to the stem itself. In our opinion it is a result of the lateral approach. However, no clinical disadvantage resulted from these ossifications.
