Q

Coracoacromial Arch

A

Coracoid process, acromion process, and coracoacromial lig (ant, post, sup)

21
Q

coracoacrominal arch serves as a (5)

A

protection from direct trauma to the humeral head, muscles, tendons, and bursae overlying the humeral head, prevents sup dislocation

22
Q

Subacromial and Subdeltoid Bursae separate (6)

A

supra tendon and the humeral head from the acromion, coracoid process, coracoacromial ligament, and deltoid

23
Q

primary causes of shoulder impingement syndrome (5)

A

inflammation in subacromial space, RTC tendon degeneration (reduced blood flow), osteophytes, hooked acromion, GH joint hyper mobility

24
Q

what muscles are most commonly involved in RTC tear?

A

Supraspinatus and infraspinatus

25
symptoms of RTC tear (4)
loss of strength, pain, decreased vascularization, sub acromial impingement
26
symptoms of labral lesion (3)
aching in the shoulder joint, catching of shoulder with movement, pain with certain activities
27
bankart lesion are generally caused by (2)
ant dislocations and shears against the labrum causing an inf tear
28
SLAP (superior labrum anterior to posterior) lesions (3)
Tear at the top socket where biceps tendon attaches, common in overhead throwing athletes, occur insidiously over time
29
type I slap lesion
sup labrum markedly frayed but attachments intact
30
type II slap lesion (2)
sup labrum has small tear and there is instability of the labral biceps complex (most common)
31
type III slap lesion (2)
bucket handle tear of the labrum that may displace into joint, labral biceps attachment intact
32
type IV slap lesion (2)
bucket handle tear of labrum that extends to biceps tendon, allowing the tendon to sublux into the joint, (needs surgery to fix)
33
Nerve entrapments (3)
brachial plexus, post (axillary and radial), suprascap
34
soft tissues: impairments of acute trauma (6)
Inflammation, pain, edema, muscle spasm, impaired movement, joint effusion (first 72 hours)
35
soft tissues: treatment during acute phase (4)
pt ed, PRICE, maintain soft tissue/joint integrity and mobility
36
soft tissues: interventions for acute stage: Maximum protective (phase 1) (4)
PROM with minimal pain, Low-dosage joint mobs (1 and 2), Muscle setting if not surgically repaired, STM
37
soft tissues: precautions during acute stage (2)
proper rest and movement
38
soft tissues: contraindications during acute stage (2)
stretching and resistance exercises with inflammation
39
soft tissues: subacute stage (2)
10-17 days but may last up to 6 weeks, collagen synthesis and fibroblast activity starts
40
soft tissues: impairments during subacute stage (3)
Pain when end of available ROM is reached, Developing soft tissue/joint contractures or muscle weakness from reduced usage
41
soft tissues: treatment during subacute stage (4)
Pt ed, Promote healing of injured tissues, Restore soft tissue/joint mobility, develop NM control/muscle endurance/strength in involved and related muscles
42
soft tissues: interventions during subacute stage: Moderate protective phase II (4)
submax isometrics, AROM, muscular endurance, and protected WB exercises
43
soft tissues: Moderate protective phase II: Initiation and progression of stretching (6)
warm tissues, STM, relaxation techniques, joint mobs/manip, stretching, use of new range
44
soft tissues: precautions during subacute stage (4)
Pain with rest, fatigue, increased weakness and spasm
45
soft tissues: chronic stage
>7 weeks, maturation and remodeling
46
soft tissues: impairments in chronic stage (7)
Length/strength imbalance, Poor posture, Soft tissue/muscle/joint contractures/adhesions that limit normal ROM/joint play, Muscle weakness and poor endurance, Decreased functional use of the region
47
soft tissues: causes of chronic inflammation (5)
overuse, repetitive strain, trauma, re-injury of old scar, contractures or poor mobility
48
soft tissues: management of chronic stage: Minimum to no protection/PLOF (4)
pt ed, Increase soft tissue/muscle/joint mobility, Improve NM control/strength/muscle endurance and CV endurance
49
soft tissues: chronic pain syndrome (3)
lasts > 6 months, pain of unknown origin, AVOID passive treatments
