What is a Sublabral foramen?
A sublabral foramen or hole is simply separation of the labrum from the underlying glenoid. It is a labral variant of no clinical significance and can be confused with a SLAP lesion.
What is Sublabral sulcus shoulder?
The superior sublabral sulcus is a normal variant of the superior sublabral recess, which is normally present at the attachment of the biceps tendon to the glenoid labrum. The superior sublabral sulcus has been described as being shallow or deep and may be continuous with a sublabral foramen if present.
What does Sublabral recess mean?
Sublabral Recess: Anterior portion of the Superior labrum not attached to the glenoid.
What is Sublabral recess shoulder?
A superior sublabral recess is located at the 12 o’clock position and represents a normal recess between the superior labrum and the cartilage of the glenoid cavity. A sublabral foramen is located at the 2 o’clock position and represents localized detachment of the labrum from the glenoid rim.
What causes Sublabral foramen?
The sublabral foramen (or hole) occurs when an intact anterosuperior labrum is not attached to the glenoid rim, typically between 1 and 3 o’clock, and has a prevalence of 11% to 21%. The middle GHL usually remains attached to this loose labrum and may appear either flat or sheet-like or thickened and cord-like.
Does a Sublabral foramen require surgery?
Even though it is believed that a sublabral foramen (SF) requires no treatment, no objective data are available to establish whether this condition bears a relationship to anterior-inferior glenohumeral instability.
What is Buford complex?
A Buford complex, found in 1.5% of individuals, is the absence of the anterior superior labrum in conjunction with a thickened cord-like middle glenohumeral ligament. A Buford complex can be confused with a sublabral foramen or pathologic labral detachment.
What does a labrum do?
The labrum is a thick tissue or type of cartilage that is attached to the rim of the socket and essentially forms a bumper that deepens the socket and helps keep the ball in place.
How rare is Buford complex?
Although the presence of a Buford complex is rare – in just 1.5% to 6.5% of shoulders – if it does occur, it may pose a potential issue for the athlete involved in an overhead sport.
Is Buford complex painful?
If the Buford complex is mistakenly surgically reattached to the neck of the glenoid cartilage, severe painful restriction of humeral rotation and elevation can occur.
What is anterior inferior?
The anterior inferior iliac spine (abbreviated: AIIS) is a bony eminence on the anterior border of the hip bone, or, more precisely, the wing of the ilium (i.e. the upper lateral parts of the pelvis).
What is the function of the anterior tibial artery?
Anterior tibial artery. The key function of this artery is to supply blood to the muscles in the anterior (front) part of the leg. As this artery goes across the interosseous membrane, it branches off into the dorsalis pedis artery, which supplies blood to the dorsal (top-most) surface of the foot.
What is posterior inferior iliac spine?
Posterior Inferior Iliac Spine. The structure indicated is the posterior inferior iliac spine of the pelvic bone. The pelvic bone consists of three parts: The posterior part of the ilium consists of two bony spines. Superiorly is the posterior superior iliac spine, and inferiorly is the posterior inferior iliac spine.
What is posterior superior iliac crest?
Projections. Posterior superior iliac spine is a bony projection located at the posterior end of iliac crest, which is situated at the level of spine of S2 vertebra and indicated superficially on the lower part of the back as a small dimple. The outer lip of iliac crest has a tubercle referred to as tubercle of the iliac crest,…
