To investigate the additive effect of sono-guided subacromial bursa injection of hyaluronate with steroid in patients with peri-articular shoulder disorders.
This prospective randomized controlled trial involved 26 patients who had shoulder pain. Group A, consisting of 13 patients, was treated with a sono-guided subacromial bursa injection containing a mixture of 0.5% lidocaine (5 ml) and triamcinolone 40 mg (1 ml), followed by injection with sodium hyaluronate (2 ml) once a week for 3 weeks. The other 13 patients (Group B) were treated with a sono-guided subacromial bursa injection containing a mixture of 0.5% lidocaine (5 ml) and triamcinolone 40 mg (1 ml) once a week for 3 weeks. The effects were assessed using a visual analogue scale (VAS) of shoulder pain, active range of motion (AROM), shoulder function assessment scale (SFA), shoulder disability questionnaire (SDQ) at study entry and every week from first injection until 4 weeks after the 1st injection (= 2 weeks after 3rd injection).
(1) Demographic features and all parameters measured before injection did not show a significant difference between the 2 groups. (2) Statistically significant improvements were shown in VAS, SFA, SDQ during the 1st, 2nd, and 4th week after the first injection in both groups (p<0.05). (3) SFA showed significant improvement at 1 week after injection only in group A (p<0.05). (4) AROM of internal rotation showed significant improvement at week 4 after the 1st injection only in group A (p<0.05).
Subacromial bursa injection of hyaluronate with steroid in patients with peri-articular shoulder disorders has additive effects on functional improvement of the affected shoulder, including the AROM of internal rotation.

Objective: To obtain a effect of intraarticular injection of Sodium Hyaluronate in the patient with degenerative osteoarthritis without restriction of activities of daily living.
Method: Twenty-five patients were participated in this study. These patients are diagnosed as degenerative osteoarthritis by clinical symtoms and radiographic findings. Sodium hyaluronate, 2.5 ml, 3 mg/ampule, were injected intraarticulary without local anesthesia once a week for 5 times consecutively. For evaluation of the effectiveness of sodium hyaluronate, we assess the parameters for subjective and objective symtoms scored from 0 to 3 on 3 items, and for activities of daily living scored from 0 to 4 on 4 items. And then, we compared these data between pre-injection and at post-injection 2, 4, and 5 weeks. Changes of subjective and objective symtoms, and activities of daily living are assessed using Kellgren's X-ray grading of degenerative osteoarthritis. Improvement of the subjective pain is recorded by visual analogue scale.
Results: 1. Subjective and objective symtoms, and activities of daily living with time progression were significantly increased at post-injection 4, 5 weeks compared with pre-injection status (P<0.05). 2. Subjective and objective symtoms, and activities of daily living according to Kellgren's X-ray classification were significantly increased at stage II and III (P<0.05). 3. Visual analogue scale is significantly decreased after injection (P<0.05).
Conclusion: Intraarticular injection of sodium hyaluronate showed improvement of patient's subjective and objective symtoms, and activities of daily living. The improvement was pronounced in the cases of high grade of degenerative osteoarthritis (stage II, III) according to Kellgren's X-ray classification as well as low grade (Stage I).
