Comparative analysis of intra-articular injection of steroid and/or sodium hyaluronate in adhesive capsulitis: prospective, double-blind, randomized, placebo-controlled study

ABSTRACT:

Background

Few studies have reported the effects of simultaneous injections of corticosteroid (CS) and hyaluronic acid (HA) on adhesive capsulitis (AC) of the shoulder. This study investigated the synergistic effects of simultaneous intra-articular injections of CS and compared them to those of CS or HA alone.

Method

Sixty patients with AC were enrolled in this randomized, placebo-controlled trial. The participants were divided into 4 groups: saline, CS, HA, and CS with HA groups. The primary outcome measure was changes in the Shoulder Pain and Disability Index (SPADI) scores at one month. The secondary outcome measures included changes in pain, range of motion, muscle strength, and additional shoulder functional scores at 1 day, 1 week, and 1, 3, and 6 months after injection.

Results

After 1 month, changes of the SPADI scores were significantly higher in the CS with HA group (−58.4%) than those in the saline (−7.7%) and HA (−14.4%) groups. The score changed more in the CS with HA group than that in the CS group (−43.7%), but there was no significant difference. In the changes in pain, the CS with HA group showed significantly better and faster effects than the saline and HA groups. In the changes of range of motion, functional scores, the CS with HA group showed better results than the saline and HA groups.

Conclusion

In the treatment of AC, the simultaneous injection of CS and HA was more effective in improving SPADI scores at one month after injection than a single injection of CS or HA.

Project description:Treatment for idiopathic adhesive capsulitis or frozen shoulder of the shoulder is controversial. The hypothesis of the study is that intra-articular corticosteroid injection in the early stages of idiopathic adhesive capsulitis will lead to a rapid resolution of stiffness and symptoms. This is a retrospective cohort study of only patients with stage 1 or stage 2 adhesive capsulitis. The diagnosis was made by history and physical examination and only when other causes of pain and motion loss were eliminated. Stage 1 adhesive capsulitis was defined as significant improvement in pain and normalization of motion following intra-articular injection. Stage 2 included patients who had significant improvement in pain and partial improvement in motion following injection. Seven patients with stage 1 and 53 patients with stage 2 comprised the baseline cohort. The mean age was 52 years (range: 30 to 78); 46 patients were female and nine patients had diabetes mellitus. Patients completed a physical examination as well as a shoulder rating questionnaire for symptoms and disability. Criteria for resolution were defined as forward flexion and external rotation to within 15 degrees of the contralateral side and internal rotation to within three spinal levels of the contralateral side. Forty-four of the patients out of 60 met the criteria for recovery at a mean of 6.7 months. The mode and median time to recovery was 3 months. The mean score at final follow-up for 41 patients using the shoulder-rating questionnaire of L'Insalata was 90 (range 52-100). The mean time to recovery for the stage 1 patients was 6 weeks (range: 2 weeks to 3 months), and it was 7 months for stage 2 patients (range: 2 weeks to 2 years). Glenohumeral corticosteroid injection for early adhesive capsulitis may have allowed patients to recover motion at a median time of 3 months. In many cases, the patients had improvement prior to the 3-month mark; however, that was the routine time for follow-up. Patients with stage 1 disease tended to resolve more rapidly than stage 2 patients. Prompt recognition of stage 1 and stage 2 idiopathic adhesive capsulitis and early injection of corticosteroid with local anesthesia may be both diagnostic and therapeutic.

Project description:Purpose:Examine demographic factors of all patients treated for adhesive capsulitis by a single surgeon, report the treatments and outcomes of these patients, and determine the effectiveness of various treatments, including corticosteroid injections and operative intervention in relation to risk factors for adhesive capsulitis. Methods:All patients treated for adhesive capsulitis by a single surgeon between 2008 to 2014 with minimum 2 years' follow-up were identified via charts and operative reports and were eligible for inclusion. Demographic information including sex and medical comorbidities was documented. Preintervention and postintervention shoulder range of motion was recorded. Specific treatment information (number of corticosteroid injections, etc) was collected. Treatment outcomes were then compared as an aggregate and among varying comorbidities. Results:Overall, 1377 patients were treated for adhesive capsulitis (946 women vs 431 men [P = .001]). For patients with adhesive capsulitis: a higher percentage of men than women had diabetes (24.8% vs 17.3% [P = .001]); nondiabetic patients had better forward flexion at initial presentation than patients with diabetes (114° vs 108° [P = .015]); more patients with diabetes required capsular release than nondiabetic patients (13% vs 7.3% [P = .003]); more nondiabetic patients resolved adhesive capsulitis without corticosteroid or surgical intervention than patients with diabetes (83.6% vs 61.7% [P = .001]); more nondiabetic patients resolved adhesive capsulitis after single corticosteroid injection than did patients with diabetes (95.9% vs 86.7% [P = .001]). Multiple intraarticular corticosteroid injections provided no added benefit over a single injection in resolving adhesive capsulitis in patients with diabetes and nondiabetic patients. Conclusion:In shoulder adhesive capsulitis, women and patients with diabetes are more commonly affected, patients with diabetes respond less favorably to physical therapy in isolation and physical therapy plus corticosteroid injections than nondiabetic patients. No benefit from multiple intraarticular corticosteroid injections was seen compared with a single intraarticular corticosteroid injection in patients with diabetes and nondiabetic patients. Patients with diabetes and nondiabetic patients have functional improvement after capsular release and manipulation if conservative treatment for adhesive capsulitis fails. Level of Evidence:III, case control.

Project description:Most forms of arthritis are incurable, difficult to treat, and a major cause of disability in Western countries. Better local treatment of arthritis is impaired by the pharmacokinetics of the joint that make it very difficult to deliver drugs to joints at sustained, therapeutic concentrations. This is especially true of biologic drugs, such as proteins and RNA, many of which show great promise in preclinical studies. Gene transfer provides a strategy for overcoming this limitation. The basic concept is to deliver cDNAs encoding therapeutic products by direct intra-articular injection, leading to sustained, endogenous synthesis of the gene products within the joint. Proof of concept has been achieved for both in vivo and ex vivo gene delivery using a variety of vectors, genes, and cells in several different animal models. There have been a small number of clinical trials for rheumatoid arthritis (RA) and osteoarthritis (OA) using retrovirus vectors for ex vivo gene delivery and adeno-associated virus (AAV) for in vivo delivery. AAV is of particular interest because, unlike other viral vectors, it is able to penetrate deep within articular cartilage and transduce chondrocytes in situ. This property is of particular importance in OA, where changes in chondrocyte metabolism are thought to be fundamental to the pathophysiology of the disease. Authorities in Korea have recently approved the world's first arthritis gene therapy. This targets OA by the injection of allogeneic chondrocytes that have been transduced with a retrovirus carrying transforming growth factor-?1 cDNA. Phase III studies are scheduled to start in the United States soon. Meanwhile, two additional Phase I trials are listed on Clinicaltrials.gov , both using AAV. One targets RA by transferring interferon-?, and the other targets OA by transferring interleukin-1 receptor antagonist. The field is thus gaining momentum and promises to improve the treatment of these common and debilitating diseases.
