What are the closed packed positions of the hand joints? - ANSWERS-MCPs cause
maximal flexion, PIPs cause maximal extension, DIPs cause maximal extension,
intermetacarpal joint cause maximal opposition
What is the optimal position for the wrist and hand to be most effective in
strengthen precision - ANSWERS-Wrist slightly extended 20 to 30°, slight ulnar
deviation, MCP flexed at 45°, DIP and PIP flexed at 15 to 30°, thumb in opposition
The most rigid and stable of the hand arches, formed primarily by the distal row
of the carpal bones - ANSWERS-The proximal transverse arch
Increases the congruity of the highly irregular joint surfaces - ANSWERS-
Sternoclavicular joint articular disc
,Ligaments of the sternoclavicular joint - ANSWERS-SC ligament, interclavicular,
Costoclavicular
Achieved by placing the arm down at the side of the body - ANSWERS-Loose
packed position of the SC joint
The shoulder girdle is comprised of which four joints? - ANSWERS-Sternoclavicular
(S/C)
Acromioclavicular (A/C)
Glenohumeral (G/H)
Scapulothoracic Articulation (S/T)
Sternoclavicular joint is what kind of joint - ANSWERS-Complex saddle joint
Achieved through maximum shoulder elevation, when the GH joint exceeds
greater than 110° of flexion or abduction. The clavicle must upwardly rotate to
achieve this. - ANSWERS-Closed packed position of the SC joint
Conditions of the SC joint - ANSWERS-Osteoarthritis, sprain, dislocation, all are
not that common, clavicular fracture is most likely
With ankylosis of a SC joint shoulder elevation is severely limited to
approximately 19° - ANSWERS-Osteoarthritis
,Can be very serious injury may require open reduction surgery - ANSWERS-
Posterior dislocation of SC joint
Most common dislocation, usually occurs due to direct trauma to the side of the
shoulder, such as an impact or a fall, typically benign - ANSWERS-Anterior
dislocation with superior medial displacement of SC joint
Acromioclavicular joint is what kind of joint? - ANSWERS-Planer joint with
incongruent surfaces
High degree of variability between individuals and within individuals - ANSWERS-
Articular disc of the AC joint
Ligaments of the AC joint - ANSWERS-Coracoclavicular ligament comprised of
coronoid and trapezoid ligaments, and AC ligament
Achieved by bringing the GH joint into 90° of abduction - ANSWERS-AC joint
closed packed position
This position is debatable - ANSWERS-Loose packed position of the AC joint
Conditions of the AC joint - ANSWERS-Osteoarthritis, osteolysis, AC joint
dislocation or shoulder separation
, Resorption of the subchondral bone of the distal clavicle, can be due to trauma or
repetitive stress - ANSWERS-Osteolysis
Common mechanism of injury is direct impact to the lateral aspect of shoulder or
a fall on outstretched hand, graded on damage to ligaments and displacement of
clavicle, six types of grades of separation, grades 4 to 6 are variations of grade 3 -
ANSWERS-AC joint dislocation or shoulder separation
One of the most mobile joints - ANSWERS-Glenohumeral
The glenohumeral joint is what type of joint - ANSWERS-Ball and socket joint
The head of the humerus articulates with what. To form the GH joint - ANSWERS-
Glenoid fossa
The GH joint at the glenoid fossa is supported by what - ANSWERS-Glenoid labum,
ligaments, joint capsule, rotator cuff
What ligaments are in the GH joint? - ANSWERS-The superior, middle, inferior,
and posterior GH ligaments
What are the rotator cuff muscles? (SITS) - ANSWERS-Supraspinatus,
infraspinatus, teres minor, subscapularis muscles
