Shoulder Orthoses Flashcards
Glenohumeral Joint
Functional Anatomy
- Mult-Axial
- Ball & Socket
- Synovial Shoulder
Most axes of rotation
AC Joint Structure
Functional Anatomy
- Plane type joint
- Synovial
SC Joint Structure
Functional Anatomy
- Saddle joint
- Synovial
Scapulothoracic Joint Structure
Functional Anatomy
Not a “true” joint
Labrum (primary function)
Functional Anatomy
to deepen the glenoid fossa (stability)
Primary Treatment Goals
Basics of SOs
- Protect soft tissue
- Prevent contractures
Secondary Treatment Goals
Basics of SOs
Correct an existing deformity
ex. arthrogryposis
Short term (Interim) Ox
Basics of SOs
Usually prefabricated
Long term (definitive) Ox
Basics of SOs
Custom Fabricated
Slings
General Information
- readily available
- easy to don/doff
Shoulder Sling
Slings
- Often uncomfortable
- Biomechanically Unsound… Protection of shoulder subluxation
- Encourages shoulder adduction / internal rotation and elbow flexion (UL pronation)
UL Pronation = GH subluxation
CVA Slings
Slings
- Padding can provide improved comfort
- Biomechanical design
- Can be adjusted to better address shoulder subluxation
- Still encourages shoulder adduction / internal rotation and elbow flexion
Dilemma with increased control
Slings
More difficult to don/doff
ex. UltraSling ER or UltraSling III
Sports Ox
Slings/SOs
Often used for instability of the rotator cuff
Two main types:
1. overhead
2. not overhead
Patient Population
Mobile Arm Supports
Mainly SCI; other Dx include Guillaume-Barre, ALS, Polio, MD
Indications:
* Limited volitional control of the shoulder
* Limited endurance for UL positioning
