Modal analysis for the assessment of cementless hip stem primary stability in preoperative THA planning

Over one million patients undergo Total Hip Arthroplasty (THA) worldwide per year. It is one of the most successful orthopedic surgical procedures with highly satisfactory outcomes, with an estimated survival rate of over 95% at 15 –20 years or more [1,2]. An increasing number of procedures are performed with cementless stems especially when treating young patients with high activity level [1,3]. Cementless total hip arthroplasty involves a press-fit condition between the stem and the femur. The primary stem stability is cru cial in order to achieve bone in-growth and good functional outcomes especially in the early post-operative period [2,4].
