Palmer, "Triangular fibrocartilage
complex lesions: a classification," Journal of Hand Surgery, vol.
The researchers isolated fibrocartilage
stem cells (FCSCs) from the joint and showed that the cells can form cartilage and bone, both in the laboratory and when implanted into animals.
The joints with fibrocartilage
and hyaline are more likely to develop CPPD; this makes the knees and wrists the most common sites.17 Radiographs of the knees will detect 90% of patients with calcifications in chondrocalcinosis, which are linear or punctuate in hyaline cartilage, but granular in fibrocartilage
Quantitative evaluation of the tendon cell density, thickness of the fibrocartilage
zone and area of proteoglycan
The anatomic structure and position of synovial joint differ from fibrous or fibrocartilage
joints and because of continuous mechanical stresses to these joints and bearing weight, these joints are more susceptible to degeneration.
At the end of treatment, a histological examination showed hyaline cartilage in the infrared laser group, fibrocartilage
in the He-Ne laser group, and granulation tissue in limbs of the control group.
High-resolution 3T magnetic resonance imaging of the triangular fibrocartilage
complex in Chinese wrists: Correlation with cross-sectional anatomy.
The collagen types I, II, and X characterize fibrocartilage
and chondrocyte dedifferentiation, typical hyaline cartilage, and cartilage hypertrophy, respectively .
The supraspinatus tendon is particularly vulnerable, since it curves along its course between the musculotendinous junction and its insertion on fibrocartilage
. Furthermore, magic angle augmentation of signal intensity within the biceps tendon may be misinterpreted as focal cuff pathologic conditions near the rotator interval.
(1) In general, small avulsions of the ulnar styloid do not require formal treatment, whereas displaced fractures of the base of the styloid involving the fovea may require operative repair, if there is clinical instability, to reestablish the attachment of the triangular fibrocartilage
Because LOX-1 and MMP-2 are expressed by fibroblasts, adventitial cells, and fibrocartilage
cells and activate the contractile function of cells during connective tissue injury , our results suggest that the hACLFs in our study underwent a self-recovery process after isolation.
The labrum is a ring of fibrocartilage
based on the glenoid cavity.
