48
where is the pain located with patellar tendinitis

50
what can be confused with popliteus tendinitis
IT band friction syndrome
51
activities that can cause tibilais posterior tendinitis

52
impingement syndrome
inflammation, pain and deems of tissues between the AC and GH joints
53
what is affected with impingement syndrome
supraspinatus biceps subacromial bursa
54
what are the 3 progressive stages of impingement syndrome
stage 1: edema & hemorrhage of subacromial bursa. stage 2: tendinitis & fibrosis. both stages are reversible with rest (stop doing activity that causes it) stretching and strengthening stage 3. incomplete tears or complete tendinous rupture. may be bony changes of acromion & AC joint. surgery usually indicated
55
what is calcification tendinitis
late occurring stage of RC tendinitis, usually occurring in the supraspinatus tendon

in flexion
58
a bursa is not palpable unless…
it is inflammed
59

60
what is the function of a bursa
reduce friction, usually between tendons and bones
61
what is a bursa
small flat sac lined with synovium. separated by lubricating fluid
62
cause of bursitis

hip flexor tightness and repetitive activity
78
where is the pain located with iliopectineal bursitis

between the glute max and ischial tub
81
how is the ischial bursa palpated
through the glute max

referral down posterior leg that mimics sciatic pain
83
what action may be painful in someone with ischial bursitis
standing in toes
84
what is the cause for ischial bursitis
- sitting for long periods in a hard surface - excessive sprinting due to hamstring contracture

how is the retrocalcaneal bursa palpated
on either side of the achilles tendon
93
what can cause retrocalcaneal bursitis
overuse and tight gastroc & soleus complex are causes of inflammation
94
bakers cyst
synovial cyst that appears on the lateral side of popliteal space
95
where does a bunion occur
at the first metatarsophalangeal joint capsule
96
what is a bunion
a former excessive bone growth, a callus and an inflamed, thickened bursa developing over the joint
97
what causes a bunion
hypermobile joint and poor biomechanics allowing the first metatarsal bone to deviate medially. the phalanges deviated laterally forming hallux valgus
