100 consecutive patients suffering with cuff disorders
Neer’s Modified Classification: diagnosed
Bursitis - Tendonitis
Partial Tear
Full thickness tear (No OA)
Cuff Tear Arthropathy
with plain radiographs & MRI
8. PATIENTS & METHODS:
EXCLUSION CRITERIA

rheumatological disesases

Adhesive capsulitis / calcific tendonitis
Diabetes
Major depressive syndrome
Previous sub-acromial injection therapies (any drug)
Age under 30 & over 80 y.o.
Shoulder Instability anterior, posterior, multidirectional, SLAP
lesions.
9. • The injective cycle consisted of 3 subacromial injections, repeated every
15 days for 3 times.
• Injections performed by the antero-lateral way, US guided (IU22- Philips- The
Netherlands).
• Sinovial® (IBSA) 0.8% - 16mg/2ml was used: obtained by biofermentation and
purification processes (MW 800-1200kD).
10. ENDPOINTS
1. To evaluate the pain reduction 15 days after the end of the
injections cycle (day 45 from first injection), relative to
baseline .
2. maintenance of pain relief measurements in a medium
term (day 90) .
3. Additional end points included improvement in terms of
global assessment by the patient and the level of
functional improvement based on the range of motion.
4. Safety assessment

For each effectiveness variable the comparisons between cuff tears grades were performed by means of an analysis of covariance
for repeated measures model, considering the baseline value of each variable as covariate .
12. RESULTS: Safety Assessment
• Overall, the treatment was well tolerated.
• No shoulder infections occurred during the observational period.
• No systemic adverse events observed.
• Common side effects were:
– Pain at the injection site:
– Headache:
–
–
Swollen mass around the needle hole:
–
•
Ecchymoses around the injection site:
Fainting due to a vasovagal reaction:
13 episodes (9/13 in Grade IV patients –aged people)
5 episodes.

14. RESULTS
Primary endpoint.
• In grades I and II, at day 45 of FU, significant reduction of VAS and increase of
Constant-Murley and OSS was recorded.
• In grade III not a meaningful improvement of the shoulder function as well
as pain relief.
• In IV grade benefits were recorded for the first 45 days, while OSS and
Constant did not show any improvement.
Secondary endpoint
• Grade I and II. Excellent global conditions. Full ROM recovery
• Grade III: Poor improvements in global conditions. Poor ROM improvement
• Grade IV: improvements in global conditions. Poor ROM improvement
15. RESULTS: VAS PAIN
VAS decreased significantly for Grade 1 and Grade2 as Grade 4 of disease, until the end of HA injective administration.
At day 45, following a period of pain reduction, in Grade 3 15 days after the last injection patients report an increasing
pain.
16. RESULTS: Oxford Shoulder Score
By OSS evaluation, as patient’s global assessment, the HA injections were effective on bursitis and partial tear. In
grade 3 at 90 days no benefits have to be reported. In Grade 4 a benefit was reported, but not meaningful in
comparison with Grades 1 and 2
17. RESULTS: Constant - Murley
The CS assessed the functional improvement of the shoulder in all the 4 grades of cuff disease. However, the grades 3
and 4, starting from the end of injective treatment showed a significant reduction, as demonstration of a temporary
effect of the injected molecule
18. CONCLUSION
…Viscosupplementation using a low-medium hyaluronate (as Sinovial®):
1. useful treatment option for patients with bursitis (grade 1)
1. used in partial tears (grade 2) to attenuate the inflammatory process,
2.
In cuff tear arthropathy (grade 4), to defer the intervention of shoulder arthroplasty or inoperable cases
3.
In full thickness lesions (grade 3) the efficacy is very poor
(grade 3 is not an indication for a HA injection therapy, even in view of a reconstructive surgery).
Overall: Safe and well tolerated
