PATIENTS & METHODS:

Bursitis - Tendonitis

Partial Tear

Full thickness tear (No OA)

Cuff Tear Arthropathy

100 consecutive patients suffering with cuff disorders

Neer’s Modified Classification: diagnosed with plain radiographs & MRI

Page 8: Isiat sinovial IBSA

EXCLUSION CRITERIARheumatoid arthritis, amiloidosis, chondrocalcinosis, gout,

rheumatological disesases

Trauma episodes on the shoulder in anamnesis

Adhesive capsulitis / calcific tendonitis

Major depressive syndrome

Previous sub-acromial injection therapies (any drug)

Age under 30 & over 80 y.o.

Shoulder Instability anterior, posterior, multidirectional, SLAP lesions.

PATIENTS & METHODS:

Page 9: Isiat sinovial IBSA

HA INJECTION TECHNIQUE

• 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).

Page 10: Isiat sinovial IBSA

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

ENDPOINTS

Page 11: Isiat sinovial IBSA

Follow up:– Before therapy – Day 15, – Day 30, – Day 45, – Day 90.

Evaluation scores: 1. VAS PAIN2. Oxford Shoulder Score 3. Constant-Murley Score

PATIENTS & METHODS

Statistical method: 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 .

Page 12: Isiat sinovial IBSA

• 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: 13 episodes (9/13 in Grade IV patients –aged people)

– Headache: 5 episodes. – Ecchymoses around the injection site: 3 episodes – Swollen mass around the needle hole: 1 case – Fainting due to a vasovagal reaction: 1 case

• Side effects in line with the current literature (Gigante et al 2011)

RESULTS: Safety Assessment

RESULTS: Demography and ROM assessment

Page 14: Isiat sinovial IBSA

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

RESULTS

Page 15: Isiat sinovial IBSA

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.

Page 16: Isiat sinovial IBSA

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

Page 17: Isiat sinovial IBSA

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

Page 18: Isiat sinovial IBSA

1. useful treatment option for patients with bursitis (grade 1)

2. used in partial tears (grade 2) to attenuate the inflammatory process,

3. In cuff tear arthropathy (grade 4), to defer the intervention of shoulder arthroplasty or inoperable cases

4. 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).

CONCLUSION

…Viscosupplementation using a low-medium hyaluronate (as Sinovial®):

Overall: Safe and well tolerated (as also confirmed by Chevalier & Migliore: Safety and tolerabilty of intra

articular HA); 2013 in press
