Hip Resurfacing remains an excellent procedure. Prof McMinn and Mr Ronan Treacy’s previous design the BIRMINGHAM HIP™ Resurfacing (BHR™) (1) proudly demonstrates an ODEP 13A* rating in the UK. (2)
Restrictions in size range and gender application in many countries relating to Metal on Metal Hip Resurfacing, limit the use of these implants to males, and component sizes from 48 to 62mm only.
JointMedica and others, are exploring alternative materials to Metal on Metal for use in Hip Resurfacings.

Encouraging results with modern polyethylene supports JointMedica’s hypothesis that Highly Cross-linked Polyethylene could offer advantages over hard on hard articulations in the longer term (4). This material concept has been explored by other authors for it’s suitability for use in Hip Resurfacings (5,6). The wear resistance and performance of these cross-linked polyethylene implants are encouraging in active patients. The requirement for a two-piece acetabular component which necessitates the need for a locking mechanism opens up discussion relating to both acetabular bone conservation, (7) and the effectiveness of acetabular liner locking mechanisms.

JointMedica are delighted to observe the growing interest in McMinn and Treacy’s newest Hip Resurfacing concept, which takes advantage of their unprecedented knowledge and experience in Hip Resurfacing design. Our unique monoblock highly crosslinked polyethylene Hip Resurfacing concept grew out of the need to offer active females, metal sensitive patients, individuals in need of a conservative revision procedure, and patients of a smaller stature, the ability to enjoy the benefits of Hip Resurfacing. The early experience with a conservative series of Custom-made implants was published on the 9th October 2019, and has now been officially downloaded over 1500 times!
