Acomioclavicular Join
W/o prior trauma
What are some radiological findigns of shoulder imingement?
- elevation of the humeral head
- Spurring at the acromion process

Shoulder impingment can also be called
Rotator Cuff Arthropathy
What is HADD?
Hydroxyapatite Depostion Disease
What is a radioloical finding for HADD
Depostion of Calcium within tendons and bursa
Where is HADD more commonly seen?
Supraspinatus tendon
Where is DJD of the knee most commonly at?
Medial tibiofemoral compartment
What is the assymmetric loss of joint space in the medial compartment of the knee called?
Genu Varus
What is another radiological finding of the midline of the knee?
Subcondral Cyst
What is HADD of the knee called
Pelligrini-Steida Calcification
What is the ligament thhat is affected by HADD of the knee?
Medial Tibial Collateral Ligament
This is multiple loose intra-articualr bodies in the knee
Synovial Osteochondrometaplasia
This is slow growing, bengin and locally invasive tumor/metaplasia of the synoivum
Pigemnted Villonodular Synovitis
Pigemented Villonodular Synovitus is most commonly in this area
knee
Some radiological findings of Pigmented Vilionodular Synovitus are
- Apple core Defromity
- in tight joints
- lobulated masses
Some radiological findings of DJD of the hip are

Acetabular Protrusion can be evaulated through
Kohlers Line
Neurotrophic Arthropathy is MC caused by
diabetes
Some sysmptoms that can be associated with neutrophic Arthropathy are
- Swollen painful ankles
- Decreased pain sensation and proprioception
Radiological findings for neuotrophic Arthropathy are
-“bag of bones”
What are the two categories of Neurotrophic Arthropathy
Hypertrophic
Atrophic
What are the joints MC affected by Hypertrophic Neurotrophic Arthropahty
