Q

Article: Progressive exercise compared with best practice advice with or without corticosteroid injection, for the treatment of patients with rotator cuff disorders.

Findings?

A

Progressive exercise was not superior to a best practice advice session with a physiotherapist in improving shoulder pain and function. Subacromial corticosteroid injection provided no long-term benefit in patients with rotator cuff disorders.

Q

Article: Treatment of non-traumatic rotator cuff tears (physiotherapy group, acromioplasty and physio group & rotator cuff repair, acromioplasty and physiotherapy group

Findings?

A

There was no significant difference in clinical outcomes between the three interventions at the two year follow up. Conservative treatment is a reasonable option for the primary initial treatment of isolated, symptomatic, non-traumatic, supraspinatus tears in older patients

Q

What are the two surgical approaches for RC repair?

A
  1. Arthroscopic RC repair (camera guided through, surgery through 2-3 small slits).
  2. Mini open RC repair - Large or complex tears or reconstruction (tendon transfers). Potentially an incision/detachment of the deltoid

Q

Influence of surgical approach on RC repair?

A
  • Open/Mini open = deltoid muscle detachment is needed to gain access to rotator cuff. This can affect the muscle’s ability to contact actively for 6-8 weeks post surgery.
  • Arthroscopic = minimal/no deltoid involvement (smaller incision)

Q

Influence of the size of the tear on rehabilitation?

A

Small (<1cm)
Medium (1-3cm)
Large (3-5cm)
Massive (>5cm)

  • > 5cm = poorer outcomes.

Note: retracted tears = greater mobilisation of the muscle

Q

Influence of tissue quality on rehabilitation?

A

Tissue quality can be good, adequate or poor

If the tissue quality is good, more aggressive rehabilitation strategies may be used because the tissues are better able to handle the stress and strain of more intense rehabilitation exercises.

Quality of muscle (eg weak), tendon and bone also important. MRI can assess this before surgery

Q

Influence of the location of an RC tear on rehab?

A
  • Tears that extend to involve posterior cuff structures (infraspinatus and teres minor) require greater protection and restriction in excessive shoulder internal rotation motion (strain on site).
  • Subscapularis tears
  • Restrict the amount of external rotation motion until early tissue healing has occurred

Q

Influence of the type of tear on RC rehab?

A
  • Cresent shaped
  • U shaped
  • L shaped
  • Retracted
  • Retraction occurs proximally – Difficult repair due to tissue tension. Rehabilitation should be more conservative.
17
Q

Influence on the type of tear on RC rehab (Acute vs gradual wear?)

A

Acute = 5%
Gradual wear = 95%

  • Stiffness is higher following acute tears. And when other procedures, such as a superior labrum anterior and posterior (SLAP) are performed concomitantly (rehab is more aggressive in these patients)
18
Q

Influence of timing of surgery on RC rehab?

A
  • Patients with immediate surgical repair progressed more rapidly in their rehabilitation than delayed surgical repair
19
Q

Influence of surrounding tissue quality on RC rehab?

A
  • Remaining rotator cuff tissue anterior and posterior to the tear is important eg supraspinatus the sub scap and infra/teres minor quality is important as these muscles play a role in humeral head compression and stability
  • If quality is fair – poor, consider a more conservative post-surgical rehabilitation protocol
20
Q

Influence of patient characteristics on RC rehab?

A
  • Age, smoking, type II diabetes, worker compensation
  • Older patients – Tissue quality reduced AND tendon to have larger tears and more complex abnormalities
  • Worker compensation – Patients with worker compensation required 2 x more time to return to work
  • Active patients pre-injury have better outcomes post surgery
21
Q

Influence of access to care on RC rehab?

A
  • Patients treated by physiotherapist generally have better outcomes than patients with home-based programs
22
Q

Surgeons philosophical approach on RC rehab?

A
  • Conservative or aggressive
  • Obviously, this will affect rehabilitation time
23
Q

Main precautions in phase 1 RC tear repair?

A
  • No pushing pulling or lifting (no heavy lifting for 4–6/12)
  • No shoulder extension, horizontal adduction or IR
  • No overhead motions
  • No excessive stretching or sudden movements
  • No supporting BW through hands or leaning on elbows
  • Don’t sleep on affected side
  • Wound Mx
  • Keep incisions dry/Use Shower sling
24
Q

Main goals in phase 1 RC repair?

A

Goals
* ↓ pain, inflammation, oedema
* Maintain integrity of repair
* Control pain
* Maintain and improve distal muscle strength
* ↑ PROM as tolerated
* Maintain ROM of cervical spine, elbow and wrist

25
Q

Advice regarding the sling following RC tear repair?

A
  • Abduction sling
  • Usually on for 6/52 (24/7 – Although see below)
  • For smaller tears 4/52 maybe indicated if the repair is good
  • Sling while sleeping, when riding in car
  • Don’t sleep on surgery side
  • Don’t drive unless cleared by MD – And only if necessary
  • Can remove sling when resting or sitting with the arm by the side
  • Remove arm from the sling 3–4 x/day to bend and straighten your elbow and move your wrist and hand
26
Q

Physiotherapy in phase 1 of RC tear repair?

A
  • Cryotherapy, Electrical stimulation
  • PROM:
  • Pendulum exercises at 0-3/52
  • Initiate PROM for shoulder flexion, and scaption 0-3/52
  • AROM: Elbow flexion and extension
  • Progressive resistance exercise: Hand gripping, exercises with putty
  • Cervical spine and upper back
  • Mobilisations as needed
  • Massage as needed
  • AROM and appropriate stretches
  • Scapula depressions (begin 1/7 post)
  • Assists person to set the scapula as
  • People tend to elevate shoulder to protect the repaired RC
  • When performing PROM (and later AAROM, AROM, isotonic exercises) – Advise people to set the scapula to ensure appropriate Scapulo- humeral – rhythm
27
Q

Attempting scapula depression following RC tear?

A

Attempting the scapula depression
* Ensure you depress the scapula
* Allow the patient to feel how scapula moves (in flexion/abduction) with their good arm
* Ask people to elevate their shoulder and then perform shoulder flexion/abduction – Difficult because the scapula is set improperly
* Don’t puff out chest or move chest forward and back
* Feel the rhomboids when performing the exercise
* Small movement

28
Q

Criteria to move to phase two of RC tear repair?

A

Criteria to move to this phase
* Incision area well healed
* Decreased pain to minimum levels
* Improved ROM
* Improved sleep patterns

29
Q

What factors result in better outcomes post shoulder Sx?

A

What factors result in better outcomes post shoulder Sx?
* No previous surgery
* Higher level of preoperative function
* Minimal rotator cuff pathology
* Overall well-being of the patient before surgery
* Surgery because of primary osteoarthritis

30
Q

What factors result in worse outcomes post shoulder Sx?

A

What factors result in worse outcomes post shoulder Sx?
* Surgery due to rheumatoid arthritis or trauma
* Severe loss of PROM
* Increased number of comorbidities
* Radiographic evidence of humeral head subluxation
* Loss of posterior glenoid bone
* Significant rotator cuff pathology
* Increased fatty degeneration of the infraspinatus, subscapularis
