To evaluate the clinical usefulness of sonoelastography in infants with congenital muscular torticollis (CMT).
The medical records of 215 infants clinically diagnosed with CMT were retrospectively reviewed. Fifty-three infants met the inclusion criteria as follows: 1) infants diagnosed as CMT with a palpable neck mass before 3 months of age, 2) infants who were evaluated initially by both B-mode ultrasonography and sonoelastography, and 3) infants who had received physical therapy after being diagnosed with CMT. We checked the thickness of the sternocleidomastoid (SCM) muscles in B-mode ultrasonography, strain ratio of the SCM muscles in sonoelastography, and treatment duration. We evaluated the correlation between the treatment duration and the following factors: SCM muscle thickness, ratio of SCM muscle thickness on the affected to unaffected side (A/U ratio), and strain ratio.
Both the thickness of the affected SCM muscle and the A/U ratio did not show significant correlation with the treatment duration (p=0.66, p=0.90). The strain ratio of the affected SCM muscle was significantly greater than that of the unaffected SCM muscle (p<0.001), and the strain ratio showed significant correlation with the treatment duration (p=0.001).
Sonoelastography may be a useful adjunctive tool to B-mode ultrasonography for evaluating infants with CMT, especially when predicting their rehabilitation outcomes.

To evaluate the effects of repeated steroid injection at subacromial bursa with different interval for patient with periarticular shoulder disorder.
Group A (n=10) received subacromial bursa injection only on their first visit, group C (n=10) received the injection on their first visit and one week later, and group B (n=10) received the injection on their first visit and two weeks later. All injections were done with a combination of 40 mg (1.0 mL) of triamcinolone and 5.0 mL 0.5% lidocaine (6 mL total). We examined the active range of motion (AROM) of the shoulder joint, visual analogue scale (VAS), and shoulder disability questionnaire (SDQ) at baseline at 1, 2, and 4 weeks after the initial injection.
In VAS, comparing the changes in VAS between groups, group B showed significant improvements compared with group A or C at 4 weeks after the initial injection (p<0.05). In SDQ, comparing the changes in SDQ between the groups, group B and C showed more improvement than group A at 4 weeks after the initial injection, but these results were not statistically significant (p>0.05). In AROM, comparing the changes in AROM of external rotation between groups, group B and C showed significant improvement compared with group A at 4 weeks after the initial injection (p<0.05).
It may be more effective in pain relief for patients with periarticular disorder to receive subacromial bursa injections twice with 2-week interval, as opposed to once.

To evaluate effects of subacromial bursa injection with steroid according to dosage and to investigate whether hyaluronidase can reduce steroid dosage.
Thirty patients with periarticular shoulder disorder were assigned to receive subacromial bursa injection once a week for two consecutive weeks. Ten patients (group A) underwent subacromial bursa injection with triamcinolone 20 mg; another group of ten patients (group B) with hyaluronidase 1,500 IU and triamcinolone 20 mg; and the other ten patients (group C) with triamcinolone 40 mg. We examined the active range of motion (AROM) of the shoulder joint, visual analogue scale (VAS), and shoulder disability questionnaire (SDQ) at study entry and every week until 1 week after the 2nd injection.
All groups showed statistically significant improvements in VAS after 1st and 2nd injections. When comparing the degree of improvement in VAS, there were statistically significant differences between groups C and A or B, but not between groups A and B. SDQ was statistically significantly improved only in groups B and C, as compared to pre-injection. There were statistically significant differences in improvement of SDQ after the 2nd injection between groups C and A or B. Statistically significant improvements in AROM were shown in abduction (groups B and C) and in flexion (group C only).
Repeated high-dose (40 mg) steroid injection was more effective in terms of pain relief and functional improvements of shoulder joint than medium-dose (20 mg) steroid injection in periarticular disorder. Hyaluronidase seems to have little additive effect on subacromial bursa injection for reducing the dosage of steroid.

To evaluate the additive effects of hyaluronidase combined with steroids in patients with peri-articular shoulder disorder.
Thirty patients with peri-articular shoulder disorder were given subacromial bursa injections once a week for three consecutive weeks. Fifteen patients (Group A) underwent subacromial bursa injections with hyaluronidase 1,500 IU, triamcinolone 40 mg and 0.5% lidocaine (total 6 ml). Another fifteen patients (Group B) underwent the same injections with triamcinolone 40 mg and 0.5% lidocaine (total 6 ml). We examined the active range of motion (AROM) in the shoulder, used a visual analogue scale (VAS) for measurement, and administered a shoulder disability questionnaire (SDQ) at the commencement of the study and then every week until one week after the third injection.
There were no significant difference between group A and B before the injections took place (p>0.05). Statistically significant improvement was seen in the VAS, SDQ, and AROM of flexion, abduction, internal rotation at one week after the first and second injections compared with the parameters measured at previous visits in both groups (p<0.05), except the SDQ between one week after the first and second injections in group B (p>0.05). Improvement in all parameters measured at one week after the third injection compared with the measurement values at one week after the second injection were not statistically significant in both groups (p>0.05). However, group A (the hyaluronidase group) showed significantly greater improvements than group B in terms of their SDQ and AROM of internal rotation scores one week after the three injections had taken place (p<0.05).
Peri-articular shoulder disorder patients who underwent subacromial bursa injections using hyaluronidase and steroids showed greater functional improvements than those who were given only steroid injections.

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.
