Belgian and French orthopedists determined a new bone-preserving straight, cementless hip stem proved less invasive, preserved bone and performed as well as other hip stems, according to a recently presented study.
Didier Mainard, MD, presented findings from the prospective study at the SICOT XXV Triennial World Congress 2011 in Prague.
“Uncemented stems can have the same good results as the cemented stem,” Mainard told Orthopedics Today in an interview.

Merits of the new stem
Mainard and colleagues theorized a stem coated with a special calcium phosphate called brushite would better preserve bone biology and invented a new uncemented stem that used the material, the Excia implant (B. Braun; Tuttlingen, Germany). The femoral prosthesis is coated proximally with titanium plasma and brushite.
