Patients should limit activities to maintain hip prosthesis
SAN FRANCISCO – In hip resurfacing the femoral ball in the
hip joint is not removed, but instead is trimmed and capped
with a smooth metal covering. Young and active patients with
arthritis often choose hip resurfacing over total hip
replacement to minimize the risk of hip dislocation, and to
preserve the bone for a

Although metal allergy with total joint replacement exists, the prevalence of
this condition is unknown, according to Joshua J. Jacobs, MD.
“Metal allergy [with] orthopedic implants has been well documented in
isolated cases,” Jacobs said during his presentation at the American Academy of
Orthopaedic Surgeons 2012 Annual Meeting/Orthopaedics Research Society
symposium. “The true prevalence is unknown. Clinically significant
symptomatologies seem to be rare in total knee replacements and
metal-on-polyethylene total hip replacements,

hip implants
Lubricant in devices found to be graphite, not proteins
A new study, bringing together an interdisciplinary team of
physicians and engineers from the United States and Germany,
made a surprising finding about implants used in hip
replacement surgery: Graphite carbon is a key element in the
lubricating layer that forms on metal-on-metal hip implants.
The lubricant has more in common with the lubrication of
