The Genotoxic Potential of Novel Materials Used in Modern Hip Replacements for Young Patients

چکیده
Total hip replacement (THR), one of the most successful and cost effective surgical interventions introduced in the last 50 or so years in medicine and the second most common elective operation in the UK (Sheldon et al., 1996, Garellick et al., 1998), owes most of its success to the introduction of hard-on-soft arthroplasty by Charnley. Arthroplasty (from the Greek ‘arthrosis’ = ‘joint’ and ‘-plasty’ = ‘the making of’) describes the surgical reconstruction or replacement of a malformed, degenerated or traumatised joint. THR is the treatment of choice for conditions that affect both the articular surfaces (i.e. acetabulum and femur) of the hip joint. Worldwide, approximately one million artificial hips are implanted annually (Smith & Learmonth, 1996). Problems with polyethylene (PE) wear debris from soft-on-hard articulations (causing an infiltration of macrophages, eventually leading to destruction of bone and soft tissue and initiating loosening of the implant) led to the development of hard-on-hard bearing combinations for artificial hips as the latter produce minimal wear and therefore implant failure is delayed.

Gelcasting as a Novel Processing Route to Fabricate Partially Stabilized Zirconia Ceramic Bodies
Bioinert ceramics, like alumina and zirconia are used mainly for replacements of bones, hip joints and for dental implants. Partially stabilized zirconia ceramics (PSZ or TZP with 3 mol.% or 5 wt.% Y2O3), appear as perspective bioinert ceramics because of their high strength and corrosion resistance. In order to fabricate complex shapes, it is essential to use a near ...
متن کاملHip Arthroplasty and its Revision in a Child: Case Report and Literature Review
Juvenile idiopathic arthritis is the leading cause of hip replacement in young children. However, arthroplasty in this population is challenging with several concerns about quality of the growing bone, young age for revision surgery, and difficulties in potential several revisions. In this study we introduce a case of a 12-year old who is one of the youngest patients to undergo revision hip art...
متن کاملA Single Femoral Component for All Total Hip Replacements Performed by a Trust? Does This Affect Early Clinical and Radiological Outcomes?
Background: Hospitals may be under pressure to implement cost saving strategies regarding prosthesis choice. Thismay involve the use of components which are not the first preference of individual surgeons, or those they have littleexperience with. We aim to examine the effect of standardizing the type of femoral stem used in a single trust, anddetermine whether this is safe practice, particular...
