Sports injuries - Dr. Faerber Flashcards
What types of shoulder injuries do you expect in a young pt? middle-aged? old?
Young Patient:
Instability, AC joint separation, dislocation
Middle aged patient:
Impingement, RTC tear, adhesive capsulitis
Old Patient:
RTC tear, arthritis, adhesive capsulitis
What area of the shoulder is more predisposed to get atritional tears with repetitive micro tears?
the supraspinatus insertion because it is supplied by the watershed zone
more likely to get small tears
what keeps the clavicle from migrating superiorly?
coracoclavicular ligaments
(conoid and trapezoid)
prime stabilizers for the clavicle for superior migration
What are the Acromioclavicular ligaments important in stabilizing?
the anterior and posterior movement of the clavicle
Which AC injury types need surgical intervention?
types 4-6
*What nerve is the most commonly injured in a shoulder dislocation?
Axillary n.
can cause numbness to the lateral shoulder
What are your static restraints of the shoulder?
The capsule and ligaments
The shape of the humeral head, glenoid and labrum.
What are the dynamic stabilizers of the shoulder?
rotator cuff and muscles
primary function is to maintain stabilization of humerus with glenoid with movement
What is the most common dislocation of the shoulder? What will this look like clinically?
anterior
Arm is held in slight abduction and external rotation.
Shoulder is “squared off” (ie, boxlike) with loss of deltoid contour compared to contralateral side.
Humeral head is palpable anteriorly (in the subcoracoid region, beneath the clavicle).
How many views are wanted in a shoulder injury?
3 views
What type of lesion needs to be corrected?
Bankart lesion
Repair labrum and shorten the capsule
*where is the most common place for tendinosis?
Extensor carpi radialis brevis tendon at the origin=most common!
Collagen degeneration due to:
- age
- microtrauma
- vascular compromise
Degeneration and inadequate repair
What is the most common elbow complaint?
lateral epicondylitis–> tennis elbow
What are common differentials for lateral epicondylitis?
(things on the lateral elbow) C6/7 radiculopathy Radial tunnel syndrome Posterior interosseous nerve syndrome Distal biceps tendon degeneration Radiocapitellar arthritis Capsular infolding Posterolateral instability
Should we think of the Ulnar Nerve when we are talking about tennis elbow?
NO! it is not at the lateral epicondyle
