Clinical assessment
• Constant and Murley score– minimum score of 0 and
maximum score of 100 – higher scores reflecting
increased function)• Total score is obtained by adding
the results of 4 subscales: – subjective pain (15 points)
– function (20 points) – objective clinician
assessment of range of motion (40 points)
– strength (25 points)
• The UCLA Shoulder Rating Scale is a 35-point shoulder scale that combines scores for – pain, from 1 to 10 points– function, from 1 to 10 points– active range of forward flexion,
strength of forward flexion (manual
muscle testing), scored from 0 to 5 points,
– patient satisfaction scored from 0 to 5 points.
• The outcome defined as follows: – 34 to 35 points, excellent; – 29 to 33 points, good; – 21 to 28 points, mild; – 20 points or less, poor.
Calcific deposit classification
• Clearly circumscribed with a dense appearance (type I)
• heterogeneous structure with sharp outline or homogenous structure with
no defined border (type II)
• Translucent and cloudy appearance without clear circumscription (type III)

Single-needle aspiration
• Prospective study, 33 patients with calcifying tendinitis had a needling under control of an image converter. At least one year follow-up period.
• Resorption of the hydroxyapatite deposits in 23 (70%);
• Remission of symptoms or considerable improvement in 75%– type I: complete resorption in 33%– type II: complete resorption in 71%; only half were symptom free – type III: complete resorption in 85%
• Surgical removal was necessary in 3 patients because of persisting pains

High versus low energy ESWT
• Shoulder pain for at least 12 months • Resistant to regular physiotherapy and
subacromial injections of steroids. • An area of radiological calcification at least
1 cm in diameter with no signs of disintegration (type I or II)
• Cloudy and transparent calcifications (type III) were excluded.
• Rotator cuff lesions were excluded by means of sonography and in some cases by magnetic resonance imaging
• Additional reasons for exclusion were evidence of subacromial impingement of the rotator cuff independent of calcareous deposits

High versus low energy ESWT• High-energy group received 1500 shock waves
of 0.32 mJ/mm2 / treatment, 120 impulses /min• Low-energy group received 6000 shock waves of
0.08 mJ/mm2 /treatment, 120 impulses /min• Adequate IV analgesia and sedation. Local
anesthetics were prohibited.
• All patients received a second ESWT treatment at 12 to 16 days
• Each treatment session lasted as long as 1 hour.
• In each group patients received a cumulative energy dose of 0.960 J/mm2.
• Sham treatment: an air-chambered polyethylene foil with coupling gel was placed against the patient's skin, but no coupling gel was applied to the site of the shock wave head.
• Calcific deposits > 5 mm in diameter, and symptoms for > 6 months.
• Rotator cuff tears and subacromial bursitis were ruled out in all patients by clinical and sonographic examination, and when in doubt, by MRI prior to randomization and at all follow-up visits.
• Type III Gärtner deposits were excluded• All participants had previous conservative
treatments, including both physiotherapy (active and passive exercise, mobilization, manual therapy and massage, muscle strengthening) and local anesthetic or corticosteroid injections.

Arthroscopy surgery versus ESWT for chronic calcifying tendinitis of the shoulder
• Retrospective study in patients with chronic calcific deposit
• Arthroscopic extirpation (group I, 22 cases)
• Low ESWT: 3 treatment sessions with 1,500 impulses/session of 0.10-0.13 mJ/mm2. (group II, 24 cases).
• Patients included in the study had– unsuccessful conservative therapy for
six months– no evidence of subacromial
impingement of the rotator cuff detected by sonography or magnetic resonance imaging.
• Ca deposits had to be types I and II / Gärtner classification.
• (UCLA) rating system after 24 months,
– group I: mean score rose from 9.36 (+/-5.2) to 30.3 (+/-7.62), with 81.81% reporting good or excellent results (P < 0.001).
– group II mean score rose from 12.38 (+/-6.5) to 28.13 (+/-9.34), with 70.83% reporting good or excellent results (P < 0.001).
• Radiologically, after 24 months,
– No calcific deposit in 86.35% (P < 0.001) of group I
– No calcific deposit in 58.33 % (P < 0.001) of group II.

Influence of deposit stage and failed ESWT on the results of arthroscopic resection of calcific tendonitis
• 45 (17 men, 28 women)– mean age of 49 +/- 8 years – mean follow-up 36 months (14-89)
• 24 patients (53.3%) underwent preoperative ESWT.
• For the clinical evaluation the – Constant and Murley Score– Simple Shoulder Test (SST)– Western Ontario Rotator Cuff Index
(WORC) – visual analog scales for pain,
function and satisfaction
• For the radiological evaluation, the classifications according to Gartner and Bosworth were used.

Take home message
• Type III Ca deposits are likely to resolve spontaneously• Needling is a simple low-cost straight forward procedure in
type II Ca deposits with persistent pain despite conservative therapy
• No significant difference in terms of pain and function between high energy ESWT and arthroscopic removal in type II Ca deposits
• Type I Ca deposits are associated with lower rate of radiographic regression with ESWT
• No significant correlation between radiographic and clinical outcomes
