How should adhesive capsulitis be managed in a middle-aged woman with diabetes?

Management of Adhesive Capsulitis in a Middle-Aged Woman with Diabetes

For a middle-aged diabetic woman with adhesive capsulitis, initiate combined treatment with intra-articular corticosteroid injections plus structured physical therapy focusing on external rotation and abduction stretching, while optimizing glycemic control to address the underlying metabolic contribution to her condition. 1, 2

Why Diabetes Matters in This Context

• Diabetic patients have significantly increased risk of developing adhesive capsulitis, with the condition being more prevalent and potentially more severe in this population 2, 3
• Hyperglycemia impairs wound healing and causes excess collagen cross-linking, which directly contributes to the capsular fibrosis characteristic of frozen shoulder 1
• Optimizing glycemic control is essential as it can prevent progression and facilitate recovery of the capsular restriction 1

Initial Treatment Approach

Corticosteroid Injections

• Intra-articular triamcinolone injections have demonstrated significant effects on pain reduction in adhesive capsulitis, with evidence supporting their use as first-line intervention 1
• These injections showed improvement in range of motion, though the improvements were not always statistically significant 1
• Short-term oral corticosteroids are an alternative option if intra-articular injection is not feasible 2

Physical Therapy Protocol

• Focus stretching exercises specifically on external (lateral) rotation and abduction, as external rotation is the most significantly affected motion and relates most strongly to shoulder pain onset 1, 4
• Implement gentle, progressive stretching exercises performed multiple times daily 1, 5
• The combination of physiotherapy and corticosteroid injections provides greater improvement than physiotherapy alone 2

Critical Movements to Avoid

• Strictly avoid overhead pulley exercises, as they encourage uncontrolled abduction and have the highest incidence of worsening hemiplegic shoulder pain and adhesive capsulitis 1, 6, 4
• This is particularly important given that improper handling during rehabilitation significantly increases adhesive capsulitis risk 6, 4

Additional Conservative Measures

• NSAIDs for pain management as part of the multimodal approach 2
• Consider acupuncture and hydrodilatation as adjunctive treatments if initial measures provide insufficient relief 2
• Shoulder strapping may be considered for pain control, though evidence shows mixed results on long-term outcomes 1

Adjunctive Modalities

• Ice, heat, and soft tissue massage can be incorporated as supportive modalities 1
• Functional electrical stimulation may improve shoulder lateral rotation and reduce pain-free lateral rotation deficits 1

Timeline and Surgical Considerations

• If minimal improvement occurs after 6-12 weeks of conservative treatment, surgical options should be considered 2, 5
• Surgical interventions include manipulation under anesthesia or arthroscopic capsular release 2, 7
• Recent evidence challenges the traditional belief that adhesive capsulitis fully resolves without treatment; persistent functional limitations occur if left untreated 2
• Failure to obtain symptomatic improvement and continued functional disability following ≥6 months of physical therapy is the general guideline for surgical intervention 5

Diabetes-Specific Management

• Target inpatient glucose of 7.8-10 mmol/L (140-180 mg/dL) if hospitalized for any reason, as hyperglycemia impairs healing 1
• Address other diabetic complications that may compound shoulder dysfunction, including peripheral neuropathy and vascular insufficiency 1
• Monitor for depression and sleep disturbances, as adhesive capsulitis significantly impacts quality of life and these factors can reduce rehabilitation participation 8, 4

Common Pitfalls to Avoid

• Do not delay formal physical therapy beyond 6-8 weeks, as shoulder immobilization directly contributes to frozen shoulder development and may result in permanent dysfunction 6
• Do not rely on "benign neglect" expecting spontaneous resolution, as recent evidence demonstrates persistent limitations without treatment 2, 9
• Ensure equal restriction of both active and passive motion in all planes is documented to differentiate true adhesive capsulitis from other shoulder pathology like rotator cuff tears or osteoarthritis 4
• Do not use overhead pulleys as this intervention has the strongest evidence for harm 1

Monitoring and Follow-up

• Early and careful follow-up observation is required to ensure selected treatments are appropriate and effective 1
• Reassess at 6-12 weeks to determine if progression to surgical intervention is necessary 2
• Continue glycemic optimization throughout treatment, as metabolic control directly impacts capsular healing 1
