  • Title: Incidence of thigh pain after uncemented total hip arthroplasty as a function of femoral stem size.
    Author: Vresilovic EJ, Hozack WJ, Rothman RH.
    Journal: J Arthroplasty; 1996 Apr; 11(3):304-11. PubMed ID: 8713911.
    Abstract:
    Two hundred seventy-one patients (297 primary total hip arthroplasties) were evaluated for thigh pain 2 years after surgery. All femoral components were identical in wedge-shaped geometry but differed in size. All components were radiographically stable. Regression analysis revealed the presence of thigh pain to be directly correlated to increasing stem size (P = .014, r = .857). An even more significant positive correlation to thigh pain was present for proximal and distal component moments of inertia for bending in the mediolateral plane. Femoral stem size has a significant effect on the incidence of thigh pain.
