“…Guidelines published by NICE in the year 2000 argue that there is 'currently more evidence of the long term viability of cemented prostheses, which, in many cases, occupy the lower end of the range of prostheses cost, than there is for uncemented and hybrid prosthesis' (National Institute for Health and Clinical Excellence, 2000). However, other studies claim that cemented hips have proved to be superior only in short-term medical outcomes and that evidence is lacking for their superiority over the long term (Ni et al, 2005).…”

SUMMARYThis paper assesses variations in the cost of primary hip replacement between and within nine member states of the European Union (EU). It also compares the cost of service with public-payer reimbursements. To do so, data on cost and reimbursement were surveyed at the micro-level in 42 hospitals in Denmark, England, France, Germany, Hungary, Italy, The Netherlands, Poland, and Spain.The total cost of treatment ranged from h1290 (Hungary) to h8739 (The Netherlands), with a mean cost of h5043 ðSTD AE h2071Þ: The main cost drivers were found to be implants (34% of total cost on average) and ward costs (20.9% of total cost on average). A one-way random effects analysis of variance model indicated that 74.0% of variation was between and only 26% of variation was within countries. In a two-level random-intercept regression model, purchasing-power parities explained 79.4% of the explainable between-country variation, while the percentage of uncemented implants used and the number of beds explained 12.1 and 1.6% of explainable withincountry variation, respectively.The large differences in cost and reimbursement between Poland, Hungary, and the other EU member states shows that primary total hip replacement is a highly relevant case for cross-border care.

“…We have conducted this comparison based on several research papers comparing the outcome of cemented versus uncemented arthroplasty. A detailed literature review, conducted by Ni et al [68], compared cemented and uncemented THA in terms of bone remodeling, pain, thigh pain, quality of life, micromotions, etc. In terms of bone remodeling, for the midterm period (2-1 Oyr after operation), they concluded that cemented THA is identical to uncemented one.…”

Periprosthetic bone loss following total hip arthroplasty (THA) is a serious concern leading to the premature failure of prosthetic implant. Therefore, investigating bone remodeling in response to hip arthroplasty is of paramount for the purpose of designing long lasting prostheses. In this study, a thermodynamic-based theory, which considers the coupling between the mechanical loading and biochemical affinity as stimulus for bone formation and resorption, was used to simulate the femoral density change in response to THA. The results of the numerical simulations using 3D finite element analysis revealed that in Gruen zone 7, after remarkable postoperative bone loss, the bone density started recovering and got stabilized after 9% increase. The most significant periprosthetic bone loss was found in Gruen zone 7 (-17.93%) followed by zone 1 (-13.77%). Conversely, in zone 4, bone densification was observed (+4.63%). The results have also shown that the bone density loss in the posterior region of the proximal metaphysis was greater than that in the anterior side. This study provided a quantitative figure for monitoring the distribution variation of density throughout the femoral bone. The predicted bone density distribution before and after THA agree well with the bone morphology and previous results from the literature.

“…In particular, the enhanced mechanical properties and bioactivity on the nanoscale can be well suited for clinical applications [7]. Our group has developed strontium-containing bioactive bone cement for vertebroplasty [8] which has low monomer toxicity, low setting temperature and stimulates bone growth in the bone cement-bone interface.…”

Review Article: Cemented or Uncemented Femoral Component in Primary Total Hip Replacement? A Review from a Clinical and Radiological Perspective

Abstract: mid-term, cemented femoral component is recommended. However, a long-term randomised trial combined with a large cohort study or registry is needed.
