SLAP 2 or 3 with tear extending into a middle glenohumeral ligament.
|
|
|
What is a SLAP 8 lesion?
|
SLAP 2 or 3 with posterior extension of the tear in the labrum from superiorly through inferiorly.
|
|
|
What is a SLAP 9 lesion?
|
The type 9 SLAP is a circumferential labral tear involving all glenoid quadrants.
|
|
|
What is a SLAP 10 lesion?
|
SLAP 2 or 3 with extension into the superior glenohumeral ligament. MR findings include a SLAP 2 or 3 tear of the superior labrum
|
|
|
SLAP fracture
|
|
|
|
Paralabral cysts indicate what?
|
Labral tear.
|
|
|
Parsonage Turner Syndrome
|
Deneration syndrome.\nSubacute increased T2 signal diffusely through the shoulder girdle muscles.\nDeltoid muscle is innervated by the axillary nerve. \nChronic phase muscle atrophy occurs.
|
|
|
Adheisive capusilitis
|
Thickening of the axillary pouch greater than 3 mm.
|
|
|
Quadlateral syndrome
|
Triangle formed by the teres minor, teres major, humerus and long head of triceps\n\n
|
|
|
What is contained in the quadrilateral space?
|
axillar nerve and posterior humeral circumflex artery
|
|
|
What is a Bennet Lesion?
|
Inflammatory changes of the bony glenoid or adjacentsoft tissues may help in establishing symptomatic fromasymptomatic Bennett lesion.
|
|
|
What is De Quervian syndrome?
|
Tenosynovitis of the abductor pollicis longus and extensor pollicis brevis tendon in the first dorsal compartment is known as De Quervian syndrome.
|
|
|
Who is it more common in men or women?
|
De Quervain tenosynovitis is more common in women (77%) and is associated with occupations that include home duties, secretarial and clerical work, and nursing.
|
|
|
What are the MRI findings of De Quervian snydrome?
|
* Thickening of tendons of first dorsal compartment.
* Abnormal signal around tendons: low signal on T1, either low signal (fibrosis) or high signal (edema) on T2. * High signal within the tendon due to partial tear or degeneration. * Obliteration of fat around the tendons. * Focal radial styloid abnormality. (Possible etiology: reactive periostitis from adjacent inflammation). The radiologic differential diagnoses for these MRI findings include atypical infections, scaphoid fracture or nonunions, radioscaphoid arthritis. However, a thorough review shows that findings in De Quervian are centered in and around the first extensor compartment (axial images are best for this). Treatment options are conservative; steroid injections and surgery by unroofing or reconstructing the fibro-osseous tunnel after failed conservative treatment. |
|
|
Os acromiale
|
anatomical condition resulting from the failure of anterior acromial ossification center to fuse to the acromial pcoess. Three separate ossification cneters appear in the acromio: preacromion, mesacromion, and metacromion.
Most common site of fusion failure are at the mesacromion and metacromion. High assocation with rotator cuff tears |
