Adhesive capsulitis of the shoulder is a common debilitating condition with prevalence in the order of 2 to 5%. Whilst it is usually a self-limiting condition, patients are typically not willing, nor are they able, to wait to the end of the recovery phase. A number of treatment strategies have been described. Manipulation under anaesthesia can significantly increase motion in all planes, but carries a significant risk of fracture. Capsular release also significantly improves motion with fewer potential side effects.

We hypothesise that performing an arthroscopic excision of the abnormal capsulitis tissue will give better results with least risk of recurrence. Data was collected both retrospectively and prospectively for patients undergoing this procedure. Range of motion and Oxford shoulder scores was documented pre-operatively and post-operatively, at 6 weeks, 3 months and 6 months. 41 patients were included. At 3 months mean flexion had increased from 101 to 152 degrees, abduction from 91 to 151 degrees, and external rotation from 18 to 44 degrees. Mean Oxford shoulder score had increased from 20.6 to 35.8 at 3 months.

The results support the use of this technique for treating adhesive capsulitis. Larger patient numbers and longer term follow up will help compare it against the other well established techniques.

Estimated to affect 2–5% of the population, adhesive capsulitis is a common cause of shoulder pain and dysfunction. The objective of this study is to determine if arthrographic injection of the shoulder joint with steroid, local anesthetic and contrast is an effective treatment modality for adhesive capsulitis and whether it is superior to arthrographic injection with local anesthetic and contrast alone.

This is a double-blinded RCT of patients with a diagnosis of adhesive capsulitis who were randomly assigned to receive an image guided arthrographic glenohumeral injection with either triamcinalone (steroid), lidocaine (local anesthetic) and contrast or lidocaine and contrast alone. Outcome measures included active and passive shoulder range of motion (ROM) and functional outcomes assessed using the Shoulder Pain and Disability Index (SPADI), the Constant Score and a Visual Analog Scale for pain. Post-operative evaluation occurred at 3 weeks, 6 weeks and 12 weeks. Descriptive statistics were utilised to summarise patient demographics and other study parameters. One-way ANOVAs compared the VAS, Constant and SPADI scores across the different time points for both study groups. The post hoc Bonferroni correction was used to adjust for multiple comparisons.

There were 37 shoulders injected with follow-up visits at 12 weeks. Twenty shoulders were randomised to receive local plus steroid and 17 shoulders received local anesthetic only. There were 21 females and 14 males with an average age of 54 years (range, 42–70). VAS scores for both patient groups were significantly improved (p<0.05) at all follow-up times. Goniometric testing demonstrated significant improvements in forward flexion and internal rotation at 90 degrees in the local group and only abduction in the local plus steroid group. There were no significant changes in the Constant scores for the local group (p=0.08), however, the Constant scores showed significant improvement for the local plus steroid group (p=0.003) at all follow-up time points. The local group showed significant improvement in their SPADI pain scores at the 12 week follow-up only (p=0.01). There were no significant differences in their SPADI disability scores (p=0.09). The local plus steroid group had significant improvement in SPADI pain and disability scores at all follow-up time points (p=0.001).

The optimal treatment for adhesive capsulitis remains unclear. Our study demonstrated that patients receiving an arthrographic injection of either steroid and local anesthetic or local anesthetic alone had significantly improved post-injection pain scores. However, only the steroid and local anesthetic group demonstrated improved SPADI disability and Constant scores. Thus, we believe that either treatment may be a good option for patients with adhesive capsulitis and can reliably relieve pain, but we would recommend the steroid with local anesthetic over the local anesthetic alone as it may provide improved function.
