“…SIS was considered to be present if the sonographer observed any evidence of bursitis or any rotator cuff abnormality including tears, tendonitis or degeneration. The diagnosis of SIS could also be dynamic, such as if the sonographer observed signs of complete or partial blocking of humeral head motion, or bunching of the bursa and/ or tendon at the acromion during shoulder abduction [ 47 – 50 ]. The US images were then read by a radiologist experienced in musculoskeletal imaging and blinded to the symptomology of the participant.…”

Background Shoulder impingement syndrome (SIS) is the most common form of shoulder pain. Conservative and surgical treatments for SIS are often not effective. One such surgical intervention is subacromial decompression, aimed at widening the subacromial space (SAS). A better understanding of the changes in the SAS may help explain the relative ineffectiveness of current interventions. Objective: To measure the acromiohumeral distance (AHD) and supraspinatus tendon thickness (STT) in people with SIS using a case control study. Methods The AHD and STT of 39 participants with SIS ≥3 months and 39 age, gender and dominant arm matched controls were measured using ultrasound imaging. Between-group differences for AHD and STT were compared using t-tests. A linear regression was used to determine if there was a relationship between AHD and STT measures, with group as a covariate. Results Compared to controls (mean age 55.7 years, SD 10.6), individuals with SIS (mean age 57.1 years, SD 11.1) had a significantly larger AHD (mean difference 2.14 mm, 95% CI 1.21, 3.07, p < 0.001) and STT (mean difference 1.25 mm, 95% CI 0.60, 1.90, p < 0.001). The linear regression model indicated an association between AHD and STT (β = 0.59, 95% CI 0.29, 0.89, p < 0.01, R2 = 0.35, n = 78), suggesting that as STT increases in size, so does the AHD. Conclusion Individuals with SIS had a larger AHD and greater STT than controls. These results suggest the SAS is already wider in people with SIS and that the symptoms associated with SIS may be more related to an increased STT than a smaller SAS.

“…Using a 3-16 MHz linear array transducer (HS50; Samsung Medicine, Seoul, Korea), supraspinatus tendon thickness of affected shoulder was measured initially in both longitudinal (at medial edge of footprint) and transverse views (two measurement sites, 5 and 10-mm posterior to edge of biceps tendon, and the average was used. [21,22] Subacromial bursa as well as acromiohumeral distance in neutral and 90° shoulder abduction were measured as well as assessment for tendon tears…”

ObjectiveEvaluate efficacy of platelet-derived lyophilized growth factors (L-GF) injection versus placebo in treatment of subacromial impingement (SIS).MethodsSixty patients with SIS (clinically and sonographically) were included in this randomized double blind placebo controlled study. Patients were randomly divided to receive either saline (group 1) or L-GF (group 2) injection, under US-guidance. Clinical examination, Visual analogue scale of pain, Shoulder Pain and Disability Index (SPADI), and shoulder ultrasound were done before and at 8th week after injection. ResultsFollow up assessment showed statistically significant improvement in L-GF group as regards active flexion & active and passive internal rotation and extension, SPADI-Disability scale, VAS of pain as well as thickness of the supraspinatus tendon by US. Concerning painful arc, regression analysis has shown that placebo group is about 30 times more than the L-GF group to get painful arc at follow up. On the other hand, both groups showed statistically significant improvement regarding SPADI-Pain scale and SPADI-Total as well as passive flexion & abduction (still mean value of abduction was significantly higher in LG-F group). ConclusionsL-GF injection in patients with SIS has resulted in significant improvement as regards pain and disability according to the improvement in shoulder range of movement, painful arc sign, VAS, SPADI, as well as significant reduction in the thickness of the supraspinatus tendon as measured by ultrasound compared to the saline group.

Background Platelet-derived lyophilized growth factors (L-GF) uses a standardized number of allogenic pathogen-free platelets instead of autologous platelets used in PRP as a source of growth factors. This study aimed to evaluate the efficacy of L-GF injection versus placebo in the treatment of subacromial impingement (SIS). Methods The current randomized double-blind placebo-controlled study included sixty patients (40 females and 20 males, aged between 24-75 years) diagnosed with SIS (both clinically and sonographically). Patients were randomly assigned to two equal groups. Group 1 received subacromial saline injection, and group 2 received L-GF injection. Both groups were injected under ultrasound guidance. Clinical examination, Visual analogue scale (VAS) of pain, Shoulder Pain and Disability Index (SPADI), and shoulder ultrasound were performed before and at the 8th week after injection. Results Follow-up assessment showed statistically significant improvement in the L-GF group with regard to active flexion, active and passive internal rotation and extension, SPADI-Disability scale, VAS of pain and thickness of the supraspinatus tendon by US. Concerning painful arc, regression analysis showed that the placebo group was approximately 30 times more likely than the L-GF group to experience painful arc at follow-up. Both groups showed statistically significant improvement regarding the SPADI-Pain scale and SPADI-Total as well as passive flexion and abduction (still the mean value of abduction was significantly higher in the L-GF group). Conclusions L-GF injection resulted in clinically significant reductions in pain and functional disability outcomes in patients with SIS. An objective significant reduction in the thickness of the supraspinatus tendon, measured by ultrasound, in the L-GF group hopefully encourages proper healing and functioning in SIS.
