Frozen shoulder/adhesive capsulitis is the progressive loss of glenohumeral range of motion (usually begins with external rotation being most limited, followed by abduction, and internal rotation).
Which phase of FS/AC is described below?
Movement patterns demonstrated as individuals attempt to compensate for lack of glenohumeral mobility; pain typically occurs with stretching at end of motion
Frozen phase
Frozen shoulder/adhesive capsulitis is the progressive loss of glenohumeral range of motion (usually begins with external rotation being most limited, followed by abduction, and internal rotation).
Which phase of FS/AC is described below?
Characterized by shoulder pain interrupting sleep, pain with ADLs, and often pain at rest; ROM usually close to full however with pain often experienced before the end of motion
Freezing phase
Frozen shoulder/adhesive capsulitis is the progressive loss of glenohumeral range of motion (usually begins with external rotation being most limited, followed by abduction, and internal rotation).
Which phase of FS/AC is described below?
Gradual return of motion and lasts up to 26 months
Thawing phase
What is the role of OT in working with someone with frozen shoulder/adhesive capsulitis?
Role of OT is to assist individuals in ADL modifications or adaptive equipment for ADLs; workstation modifications may also be considered.
Overstretching and pushing the joint to the point that reinitiates the inflammatory process should be avoided.
Up to 70% of shoulder disorders are related to rotator cuff disease. Structures involved include muscles of the rotator cuff, the long head of the biceps tendon, the subdeltoid–subacromial bursa, and the coracoacromial (CA) arch.
What are some nonoperative treatments OT can partake in to support their client with RTC disease?
Initially, focus is on rest and anti-inflammatory modalities.
Early ROM exercises (pendulum and wand-assisted elevation in scapular plane)
Strengthening the healthy part of the rotator cuff and scapular stabilizer muscles; isometrics and resistance band exercises may be considered
When is surgery for rotator cuff disease indicated?
Indications for surgery include full or partial tears that have not responded to conservative care and that continue to interfere with participation in ADLs.
How many weeks post-op for rotate cuff repair should a patient be immobilized?
2-4 weeks
After the immobilization period for a post-op rotator cuff repair, how soon after can an OT work with a client on range of motion? Strengthening?
Therapy then begins to regain ROM, progressing from passive to active motion exercise for the next 2 to 3 weeks.
At 8 to 10 weeks following surgery, strengthening exercises are initiated.

What is a closed reduction (CR) fracture repair?
A procedure that realigns a broken bone without surgery.
A doctor or other medical professional pushes or pulls the ends of the broken bone back into place.
What is an open reduction, internal fixation (ORIF) repair?
A surgical procedure that stabilizes and heals broken bones using plates, screws, and/or other special devices.
A doctor surgically repositions the broken bones and then uses special devices to hold them in place while they heal. Often, they are not removed.
Modalities for pain relief and tissue healing include… (name at least 3)
heat
ultrasound
cryotherapy (ice)
paraffin
transcutaneous electrical nerve stimulation (TENS)
True or false: Some fractures can heal on their own without surgical intervention or with a fabricated orthotic.
True!
It depends on the type of fracture and severity.
True or false: Early mobilization is often contraindicated.
FALSE
Early controlled mobilization through therapeutic exercises can HELP keep unaffected bones, tendons, and muscles strong and functional, and reduce the instances of tightness and adhesions.
How soon after injury should an OT consider intrinsic tightness versus extrinsic tightness, joint capsule tightness, and tendon adhesion?
3–8 weeks post fracture or surgery
This type of fracture is the most common UE fracture, usually resulting from a fall on an outstretched hand (FOOSH).
Distal radius fracture
This type of fracture is a complete distal radius fracture with dorsal displacement (radius moves dorsally). It is the most common type of wrist fracture.
Colles fracture
Can also be referred to as a dinner fork deformity.
This type of fracture is a complete distal radius fracture with volar displacement (radius moves volar). It results from a fall on a flexed wrist.
Smith’s fracture
It is common to see this type of wrist fracture alongside a distal radius fracture (uncommon to see them in isolation).
Distal ulna fractures
Include injuries to the ulnar styloid, ulnar head, or ulnar metaphysis.
These type of fractures are the most common fracture seen and missed in injuries to the wrist
Carpal fractures
The most common bone fractured is the scaphoid, accounting for 90% of all carpal fractures.
Lunate fractures are associated with Kienbock’s disease, a pathological process where blood flow to the lunate is compromised.
This type of fracture-related nerve injury produces carpal tunnel–like symptoms, such as palmar numbness and numbness of the first digit to half of the fourth digit. It also produces generalized weakness and pain.
Median nerve injury
This type of fracture-related nerve injury results in a claw deformity. It produces numbness of the medial side of the hand and the fifth and half of the fourth digits. It also produces generalized weakness of the ulnar side of the hand and pain.
Ulnar nerve injury
This category of fractures occurs when a bone is fractured but overall anatomical alignment is maintained.
Nondisplaced fractures
This category of fractures occurs when a bone breaks and it is no longer aligned.
Displaced fracture
This category of fractures occurs outside of the joint and does not interrupt articular cartilage; often requires little intervention
Extraarticular fracture
This category of fractures extends into the joint and can lead to osteoarthritis.
Intraarticular fracture
