Calcific Tendinopathy of the Shoulder

 

Introduction[edit | edit source]

Calcification of the supraspinatus

Calcific tendinopathy (CT) of the shoulder is a common, painful condition identified by the existence of calcium deposits in the rotator cuff tendons.[1] It usually results in shoulder pain with decreased range of motion. Diagnosis is made by shoulder x-rays, with visible signs of calcium deposits overlying the rotator cuff insertion.Treatment consists of NSAIDs, physical therapy, corticosteroid injections and ultrasound-guided needle lavage. Those who fail conservative treatment may choose to have arthroscopic decompression of the calcium deposits.[2]

Epidemiology[edit | edit source]

Usually occurs in middle-aged patients between the ages of 30 and 60, with a slight preference for females.[3]

Pathogenesis[edit | edit source]

Current theories indicate that CT may be the result of a cell-mediated process in which calcium deposition occur followed by their spontaneous resorption. However, in a few cases, this self-healing process is disrupted, causing symptoms. Literature now is showing that biological and genetic factors may underlie CTs genesis.. These new finding may explain why most of the therapies currently in use provide partially satisfactory outcomes.[1]

Localisation[edit | edit source]

  • Supraspinatus tendon (80% of cases): critical zone - Most Common
  • Infraspinatus tendon (15% of cases): lower 1/3
  • Subscapularis tendon (5%of cases): pre-insertional fibers[4]

Characteristics/Clinical Presentation[edit | edit source]

The chief patient complaints to expect in calcific tendinopathy are:

  • Night pain, causing loss of sleep.[5][6][7][8].
  • Constant dull ache[8].
  • Pain increases considerably with AROM[8].
  • Decrease in ROM, or complaint of stiffness [9][7][8].
  • Radiating pain up into the suboccipital region, or down into the fingers[5][6][8].
    The condition goes through 4 stage, see table below.
Stages[8]
Stage Name Presentation
 Chronic (Silent)
 Phase
  • Presence of the calcific deposit 
    is asymptomatic and may be so for years.

Acute Painful Phase

  • Severe pain, disability, and
    frequently nocturnal discomfort.

Mechanical Phase 

  • Tendon impingement being a prominent finding
  • Pain of less severe nature than the acute phase

Differential Diagnosis[edit | edit source]

  • Incidental calcification: found in 2.5-20% of 'normal' healthy shoulders.
  • Degenerative calcification: found tendons with tear history; generally smaller; slightly older individuals
  • Loose bodies: associated chondral defect; associated secondary osteoarthritis[3]

Outcome Measures[edit | edit source]

Medical Management[edit | edit source]

Nonoperative

  1. NSAIDs, physical therapy, stretching & strengthening, steroid injections
  2. Extracorporeal shock-wave therapy as an adjunct treatment. Most useful in refractory calcific tendonitis in the formative and resting phases
  3. Ultrasound-guided needle lavage vs. needle barbotage (needle to break up calcium deposit)

Operative: surgical decompression of calcium deposit.[2]

Physiotherapy[edit | edit source]

Physiotherapy techniques include

  • Range of motion exercises to avoid articular stiffness
  • Strength exercises to restore normal shoulder/scapular mechanics.
  • Scapular dyskinesia can cause subacromial impingement and a rehabilitation program that addresses this issue has been shown to reduce shoulder pain[1]. See link for detail.

See Therapeutic Exercise for the Shoulder

There is evidence supporting the use of extracorporeal shock wave therapy (ESWT) as a potentially effective treatment of calcific tendinopathy. See above link.[11] But ECSW is not free from complications, that included transient bone marrow edema and even reported cases of humeral head necrosis.[12][13]See Tendinopathy Treatment Adjuncts
