Flashcards in MSK- Shoulder Joint Deck (18):
Abduction up to 15 degrees
Abduction from 15-90 degrees
Middle Fibres of the Deltoid
Abduction from 90 degrees
Scapula rotated by Trapezius and Serratus Anterior
Contraction of Subscapularis
Contraction of Infraspinitus
Which dislocation is most prevalent?
What blocks superior movement?
What nerve can be damaged by injuries to the Shoulder Joint?
Causes loss of sensation in regimental patch area and paralysis of Deltoid
Can also stretch the Radial Nerve
What is rotator cuff tendinitis?
Inflammation of the muscle tendons usually due to overuse
Causes painful arc syndrome (pain at mid abduction)
Which arteries supply the shoulder joint
Anterior/Posterior Circumflex Humeral arteries
Nerves which supply
What are the joints that articulate in the shoulder?
Head of Humerus
Glenoid Cavity of Scapula
Why is it unstable?
Head is much larger than the cavity
Glenoid labrum tries to stabilise, 'deepens' the Glenoid fossa
What are the ligaments of the Rotator Cuff, and their location?
Glenohumeral - superior, middle, inferior
Transverse Humeral Ligament
Muscles in the Shoulder Joint (Rotator Cuff muscles)
