1st Handout Flashcards
Grade 3 according to ligamentous injury scale?
Tenderness to palpation with significant joint laxity and no end point
In SC joint sprains, 2/3 of the dislocations occurs where? Its causes medial end of the clavicle to become more prominent.
Anteriorly
In SC joint sprains 1/3 of the dislocation occurs where? It has more pain with less prominent medial clavicular end associated with vascular compromise.
Posteriorly
80% of clavicular fx occurs where?
Middle third of the clavicle
Most common cause of clavicular fx
Direct blow to the point of the shoulder
What is the management for clavicular fx with good alignment
Partial immobilization using sling or figure of 8 bandage
Surgical intervention should be considered in clavicular fractures if?
15 to 20mm shortening occurs
Grade 2 according to ligamentous injury scale?
Tenderness to palpation with joint laxity but a good end point
Tenderness to palpation without joint laxity?
Grade 1
It accounts for 9% of all shoulder injuries, are most frequent in males in their 3rd decade of life and usually partial rather than complete
Acromioclavicular joint sprain
MOI of AC joint sprain
Direct trauma from a fall or blow to the acromion
Rockwood classification 1
Mild injury to the AC ligaments, & radiologic evaluation is normal
Rockwood type 2
Torn AC ligaments + intact CC ligaments. Clavicular elevation <25% displacement
Rockwood type 3
Torn AC and CC ligaments, intact deltotrapezial fascia. 25 to 100% increase in the coracoclavicular space
Rockwood type 4
Torn AC and CC ligaments + posterior displacement of the distal clavicle into the trapezius muscle
Rockwood type 5
Torn AC and CC ligaments + rupture of deltotrapezial fascia that will increase in cc interspace >100%
Rockwood type 6
Torn ac and cc ligaments and deltotrapezial muscular attachments; distal of the clavicle below the acromion or the coracoid process
What type of ac joint sprains are usually treated non-operatively
Type 1,2,3
Indications for surgical intervention for type 3 AC CC sprains?
Persistent pain or unsatisfactory cosmetic results
What are the types of sprains that requires surgical treatment
Type 4 ,5,6
It is due to repetitive overload of the distal clavicle
Usually young weight lifters who perform significant amount of bench press and military press.
Osteolysis of the distal clavicle
Often referred as snapping scapula or scapula crepitus
Scapulothoracic crepitus
Three primary types of sounds in scapulothoracic crepitus
Gentle friction
Loud grating sound
Loud snapping sound
Scapulothoracic sound due to physiologic cause
Gentle friction sound
Scapulothoracic creptius; soft tissue disease such as bursitis, fibrotic muscle, muscular atrophy, anomalous muscular insertions, excessive thoracic kyphosis or thoracic scoliosis, scapulothoracic dyskinesis or winging
Loud grating sound
Scapulothoracic crepitus; bony pathology such as osteophyte, a rib or scapular osteochroma, hooked superomedial angle of the scapula, malunion of rib fractures
Loud snapping sound
Repetitive microtrauma and outlet impingement between the acromion and greater tuberosity of the humerus is more common
Rotator cuff tendinitis and impingement
Neer stage 1
Inflammation and edema in the rotator cuff
