preservation allows for better support of the implant and associated screws.
However, the procedure has been successfully applied to other joints as surgeons witnessed the benefits of treating subchondral bone
four full rotations of the thread diameter of 5 mm for direct insertion into subchondral bone
layer without the need for drilling, with two threads constructed of a material biowchlanialnego and niewchlanialnego having a strength min.
Total knee replacement (TKR) is most commonly caused by osteoarthritis of the knee, and can result in loss of articular cartilage, subchondral bone
sclerosis, bone spurs and degenerative subchondral cysts.
There are "broad areas of subchondral bone
a) ulnocarpal abutment syndrome: subchondral bone
marrow edema and cystic changes of the ulnar margin of the lunate, triangular fibrocartilage degeneration or tear, frequently with positive ulnar variance (Figure 5);
All types cause damage to the subchondral bone
, labrum, and cartilage and osteoarthritis by repetitive anterosuperior contact (15).
A number of studies have shown that subchondral bone
marrow edema developes as a result of inflammation in various sites such as the sacroiliac joints, femoral heads, and the shoulders.
marrow lesions ("bone bruises"), another feature of cartilage damage, also showed either worsening or no change in both study groups.
BML, most easily detected by magnetic resonance imaging (MRI), is identified by inflammation surrounding a microscopic insufficiency fracture within the subchondral bone
We began to think of cartilage and the bone underneath it, called subchondral bone
, as functioning as a single unit.
To investigate the three dimensional structures of the collagen fibrils in articular cartilage, full thickness canine humeral cartilage was microtomed into perpendicular sections that include the articular surface to the subchondral bone
and approximately 100 successive parallel sections, each 6 pm thick.
