3D computer models.
Cartilage defects appear as synovial fluid-filled, T2 hyperintense gaps that disrupt the articular surface
Being also compatible with the erasured articular surface
, it was used for resurfacing the articular surface
It was found that by rinsing the articular surfaces
with a lipid solvent friction increases by 150% .
Attachment areas for ligaments and muscles are strongly developed while the degenerative changes to the articular surfaces
are not severe except where there has evidently been a reaction to trauma.
The trial of the Ci Articular Surface
Replacement (Ci ASR) system was carried out at Cardiff's Bupa Hospital and 25 patients have benefited from the new technology.
These edema-like signals may represent pulsion of joint fluid through breaks in the articular surface
, localized inflammation, or changes associated with trauma due to biomechanical incompetence of the articular surface
As it extends slightly superiorly and posteriorly it overlaps the inferior articular surface
of the patella and the anterior aspect of the femoral condyles (Figures 2-4).
The fracture was spiral in nature and traveled completely down and adjacent to the articular surface
of the ankle.
MINNEAPOLIS -- Attorneys Fred Pritzker and David Szerlag are representing numerous patients who have sued Johnson & Johnson (J&J) for failed articular surface
replacement (ASR) hip implants manufactured by J&J unit DePuy Orthopaedics, Inc.
The humeral head diameter was measured with a best fit sphere; the humeral head thickness was measured from a plane defining the anatomic neck, and the articular surface
area was calculated using this sphere diameter and associated thickness.
It is widely understood in orthopaedics that oxidation is a primary cause of articular surface
decay, which can increase wear leading to osteolysis and implant failure.
