Clinical Notes : Orthopedics and Trauma

72. Frozen Shoulder

If the presenting shoulder pain is not referred from the neck then consider :

  1. Frozen shoulder

  2. Acromioclavicular joint pain

    • AC disruption

    • AC osteoarthritis

  3. Rotator cuff pain

    • Impingement

    • Tear

    • Calcific tendonitis

  4. Shoulder instability

    • SLAP tear

    • Dislocation

  5. Glenohumeral arthritis

Urgent referral if shoulder pain in the presence of :

  • History of trauma with acute pain & weakness

    • AC joint tear or displacement

    • Rotator cuff tear

  • History of trauma or epileptic fit leading to loss of rotation

    • SLAP tear

  • History of instability or subluxation

    • Dislocation

  • Mass/swelling/erythema

    • Infective process

Frozen Shoulder

 

In frozen shoulder (adhesive capsulitis)  the capsule of the shoulder joint becomes inflamed, thickened and scarred, causing pain and stiffness of the shoulder.

  • occurs in about 2-5% of the population

  • most commonly in those aged 40 to 60 years old

  • more often in postmenopausal women

 

Etiology

  • often unidentifiable

  • after injury

  • after surgery

  • after prolonged immobility

  • more common in diabetes and hyperthyroidism

 
 

Diagnosis :

There are usually three phases of a frozen shoulder:

  • Freezing:

    • This phase lasts for between 6 weeks to several months.

    • The shoulder also gradually gets very stiff and loses most of its range of motion

    • Pain

      • gradual onset that becomes progressively worse

      • usually aching in nature and felt over the back and outer shoulder area and down the arm.

      • aggravated by trying to move the shoulder

      • can be extremely severe and cause sleepless nights.

  • Frozen:

    • This phase lasts for approximately 6 months.

    • Pain itself may get better but the stiffness remains.

  • Thawing:

    • The stiffness slowly improves.

    • Complete recovery back to normal, or near normal strength and range of motion takes up to a further 2 years.

Management :

Although frozen shoulder usually gets better by itself over the course of 3 years, the symptoms are often severe enough to require treatment.

The main aim of treatment is to relieve the pain and maintain and restore the range of motion

  • Non-surgical

    • NSAIDs

    • stretching excercises

    • physio, including Transcutaneous Electrical Nerve Stimulation (TENS)

    • steroid injection

  • Surgical

    • Capsule stretching under anaesthesia

    • arthroscopic release
