Accessory Structures of the Eye

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Cranial Bones: Superior and Posterior View

Cranial Bones: Superior and Posterior View

The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Summary

This summary is machine-generated.

Elite athletes show a higher incidence of trochlear clefts, a type of knee cartilage lesion. These findings suggest clefts may be an incidental MRI finding, even in athletes with normal physical exams.

Background:

A trochlear cleft is a recently identified vertical, low-signal cartilage lesion in the trochlear groove.
Understanding its prevalence in athletes is crucial for diagnosis and management.

Purpose of the Study:

To determine the incidence of trochlear clefts in collegiate volleyball players.
To correlate MR imaging findings with clinical and physical examination results.

Main Methods:

Bilateral knee magnetic resonance (MR) imaging was performed on 16 female collegiate volleyball players.
Musculoskeletal radiologists assessed trochlear cartilage for normal, at-risk, or cleft criteria.
Statistical analysis included Fisher exact and Mann-Whitney U tests.

Main Results:

Four knees (13%) in 3 athletes had diagnosed trochlear clefts; 6 knees (19%) were at risk.
Contralateral abnormalities were present in 67% of players with unilateral lesions (P=0.0783).
All athletes had normal functional and physical examination findings.

Conclusions:

Elite athletes exhibit a higher incidence of trochlear clefts compared to the general population.
There is a risk of bilateral disease, and clefts may be incidental MR findings.
Trochlear clefts did not correlate with clinical symptoms or physical examination findings in this cohort.
