Anatomy
Formed by the junction of the superior and medial borders.
What is the superior angle?
Central ray is 1" inferior to the coracoid process.
What is the AP, shoulder, internal, external, neutral position?
Malignant tumor arising from cartilage cells
What is chondrosarcoma?
Patient is in the upright position before a vertical grid. The height of the IR is positioned at midpoint at the same level as the AC joints
What is the Pearson Method?
Thickest part of the body of the scapula.
What is lateral angle?
Slopes posteriorly at an angle of 25 deg and has three flattened impressions for muscle insertions.
What is the greater tubercle?
2" medial and 2" inferior to the superolateral border of the shoulder
What the AP Oblique projection of the shoulder joint? (Grashey Method)
Inflammation of the bursa
What is bursitis?
CR directed through the posterosuperior region of the shoulder at an angle of 45 deg caudal.
What is the Laquerriere-Pierquin Method?
Epicondyles are adjusted at a 45 deg angle with the plane of the IR.
What is the neutral rotation of the humerus?
Forms a synovial ball and socket joint allowing movement in all directions.
What is scapulohumeral articulation?
CR enters the midcoronal plane at the level of the surgical neck.
What is the transthoracic lateral projection? (Lawrence Method)
Impacted fracture of posterolateral aspect of the humeral head with dislocation.
What is Hill-Sachs defect?
Used in cases when suspected AC subluxation or dislocation.
What is the Alexander Method?
Situated on the anterior surface of the bone immediately below the anatomic neck.
What is the lesser tubercle?
Articulates with the manubrium of the sternum and the first costal cartilage.
What is the sternal extremity?
CR enters horizontally through the axilla to the AC region
What is the inferosuperior axial projection? (Lawrence Method)
Form of arthritis marked by progressive cartilage deterioration in synovial joints and vertebrae.
What is Osteoarthritis or degenerative joint disease?
Used to detect scapulohumeral dislocations, glenoid fractures, Hill-Sachs lesions and sofit tissue calcifications.
What is the Garth Method?
Epicondyles are adjusted perpendicularly to the plane of the IR.
What is AP internal rotation of the humerus?
Formed by the junction of the of the medial (vertebral) and lateral borders and lies over the seventh rib.
What is the inferior angle?
CR enters perpendicularly to the scapulohumeral joint
What is the PA Oblique projection? (Scapular Y)
Loss of bone density.
What is osteoporosis?
Called the supraspinatus "Outlet" and is Performed in the RAD or LAO position with 45 to 60 deg rotation from the plane of the IR
What is the NEER Method?
Large, smooth, rounded structure that lies in an oblique plane on the superomedial side of the humerus.
What is the head of the humerus?
