fyi
ROM of the humerus on the glenoid cavity where motion at the scapula is STABILIZED
Think pure ROM of the GHJ
Glenohumeral motion
ROM of the humerus and the scapula moving together
- Brings us to the 2:1 ratio of scapulohumeral rhythm
- More of a functional motion of your patient or how your patient moves at home when you’re not there to cue or assist them
Shoulder complex motion
The scapula
Bones and Landmarks of the Shoulder Girdle
These make up the girdle (Scapula, Clavicle,& Sternum)
Name the landmarks of the Scapula
- Superior angle – levator scapula attaches here
- Inferior angle – determines scapular rotation
- Vertebral border – rhomboid, serratus anterior attaches here
- Axillary border – the lateral side between glenoid and inferior angle attachments of teres major/minor
- Spine of scapula – middle and lower trapezius attach here
- Coracoid process – attachment of pectoralis minor
- Acromion process – attachment of upper trapezius and attachment of middle deltoid
- Glenoidfossa – concave surface that articulates with the humerus
What are the landmarks of the clavicle?
- Sternal end – articulates on the medial end with the sternum
- Acromial end – attaches laterally to the scapula and provides attachment with the upper trapezius
- Body – Between the two ends
The Sternum- parts
- Manubrium – the superior end, providing attachment for the clavicle and first rib
- Body – the middle 2/3rds of the sternum, providing attachment for the ribs
- Xiphoid Process – the inferior tip
Sternoclavicular joint “SC joint” – name the ligaments
- Sternoclavicular ligament(capsular ligament)
- Costoclavicular ligament
- Interclavicular ligament
- Acromioclavicular ligament
Scapulohumeral Rhythm
explain The relationship between the shoulder girdle and the shoulder joint
- The first 30 degrees of shoulder motion are PURE shoulder motion (glenohumeral joint only)
- After the first 30 degrees, for every 2 degrees of shoulder flexion or abduction, the scapula must rotate upwardly 1 degree
- 2:1 ratio
This provides the shoulder girdle with its only direct attachment to the trunk.
This is a plane type, synovial joint and has a double gliding motion.
Motion occurs in 3 planes: elevation/depression, protraction/rectraction, and rotation
Sternoclavicular joint “SC joint”
what are the 4 scapular motions?
- Elevation/Depression
- Protraction/Retraction
- Upward/ Downward Rotation
- Tilt
These are Scapular companion motions of the shoulder girdle that occur with shoulder jt motions(i made seperate slides as well)
(think when you flex your shoulder, your shoulder blade does what…..)
These are the shoulder jt motions. Name what motions that are occuring in the shoulder girdle at the same time.
- Flexion –goes with number 1 on flipside
- Extension –
- Hyperextension –
- Abduction
- Adduction –
- Medial rotation –
- Lateral rotation –
- Horizontal abduction –
- Horizontal adduction –
- upward rotation, protraction
- donward rotation, retraction
- scapular tilt
4 upward rotation
- downward rotation
- protraction
- retraction
- retraction
- protraction
name the Scapular Muscles
TLRSP
(tell her (r) shes pretty =when she shimmies her shoulers)
- Trapezius – all divisions
- Levator Scapulae
- Rhomboids
- Serratus Anterior
- Pectoralis Minor
what is defined as muscles pulling in different directions to accomplish the same motion?
Force couples
what muscles are involved in a force couple of Upward rotation of the right scapula?
- Upper trapezius- up counter clockwise medially
- Lower trapezius- up counter clockwies laterally
- Serratus anterior- downward straight
What muscle are involve in force couple of Downward rotation of the Right scapula?
- Levator scapula- sraight up
- Rhomboids- up clockwise medially
- Pectoralis minor- down clockwise medially
Name the landmarks of the scapula when you are talking about the shoulder joint. pg 133
- Glenoid fossa- articulates wiht humerus
- Glenoid labrum – fibrocartilaginous ring attached to the GF rim, deepening the articular cavity
- Subscapular fossa – provides attachment of subscapularis
- Infraspinatous fossa – provides attachment of infraspinatous
- Supraspinatous fossa – provides attachment of supraspinatous
- Axillary Border- attacment for teres minor and major
- Acromion process- provides attacment for middle deltoid
Name the important landmarks of the Humerus when talking about the shoulder joint.
- Head – articulates with the scapula
- Surgical neck – just below the tubercles where the head meets the body
- Anatomical neck – the circumferential groove separating the head from the tubercle
- Shaft – the body of the humerus
- Greater tubercle – attachment for supraspinatous, infraspinatous, teres minor
- Lesser tubercle – attachment for subscapularis
- Deltoid tuberosity – on lateral side near tmidpoint but not well defined
- Biciptial groove - contains the tendon of the long head of the biceps
-
Bicipital ridges-(lat & med lips of the bicipital groove)
- Lateral – pectoralis major
- Medial – latissimusdorsi and teres major
Fibrocartilaginous ring attached to the GH rim, deepening the articular cavity
Glenoid labrum
provides attachment of subscapularis on the scapula.
Subscapular fossa
provides attachment of infraspinatous on the scapula
Infraspinatous fossa
provides attachment of supraspinatous
Supraspinatous fossa
on the humerus it articulates with the scapula
Head
on the humerus just below the tubercles where the head meets the body
Surgical neck
On the humerus the circumferential groove separating the head from the tubercle
Anatomical neck
what is the body of the humerus known as?
The Shaft
name attachment on the humerus for supraspinatous, infraspinatous, teres minor
Greater tubercle
attachment for subscapularis on humerus
Lesser tubercle
on the humerus this is on the lateral side near the midpoint but not well defined

where do these attach on the humerus?
Lateral – pectoralis major

These ligaments reinforce the anterior portion of the capsule. They are not well defined ligaments but acutally pleated folds of the capsule
The superior, middle, and inferior Glenohumeral ligaments
This attaches from the lateral side of the coracoid process and spans the joint anteriorly to the medial side of the greater tubercle. pg 134
It strengthens the upper part of the joint capsule.
