The nuchal fibrocartilaginous pseudotumor described by O'Conell et al is a lesion with a characteristically specific location in the posterior aspect of the nuchal ligament, at its attachment to the deep cervical fascia, in the midline at the level of C4-5 or C5-6.
8] Other entities, such as the calcifying fibrous pseudotumor and the fibromatosis, do not have a fibrocartilaginous component.
Unlike SLAP tears in the shoulder, tears of the acetabular labrum are more commonly seen as contrast tracking between the fibrocartilaginous
labrum and the acetabular rim (Figure 16), rather than tracking into the substance of the labrum itself.
The plantar plate is a fibrocartilaginous
structure that extends from the metatarsal neck to the base of the proximal phalanx.
Examination of resected sections may reveal fragments of weakly mineralized trabecular bone proximally, dense scar tissue distally, and a thin, unorganized hyperplastic fibrocartilaginous
1) Several types of tibia vara have been recognized and include infantile, juvenile, adolescent, and a rare type caused by focal fibrocartilaginous
These important fibrocartilaginous
structures help to distribute load, increase contact area, decrease contact stress, protect cartilage, enhance stability, and provide lubrication to the joint.
This condition was described as early as 1863, when Gruber noted the presence of an os acromiale with fibrocartilaginous
union of the anterior acromial ossification centers in three out of 100 cadaveric specimens (in a review by Kurtz and colleagues (2)).
Microfracture patients all had a fibrocartilaginous
repair, while all OATS repairs retained their hyaline cartilage at one year.
The glenoid labrum is composed of fibrocartilaginous
tissue that serves to broaden the articular surface and increase load distribution in the shoulder joint.
7) However, most of long-term follow-up studies do not demonstrate adequate pain relief, probably due to fibrocartilaginous
repair tissue that lacks the durability and the mechanical properties of articular hyaline cartilage.
The labrum is a triangular fibrocartilaginous
structure that occupies the transition zone between the underlying articular cartilage of the glenoid and the fibrous tissue of the joint capsule.
