Initial Management of Adhesive Capsulitis (Frozen Shoulder)
The initial management for adhesive capsulitis (frozen shoulder) should include a combination of physical therapy, oral anti-inflammatory medications, and intra-articular corticosteroid injections as first-line conservative treatment. 1, 2
Diagnostic Approach
- Standard radiographic evaluation should include at minimum three views: anteroposterior (AP) views in internal and external rotation, and an axillary or scapula-Y view to rule out other pathologies 3, 4
- Radiographs should be performed with the patient in an upright position, as shoulder malalignment can be underrepresented on supine radiography 4, 5
- MRI or ultrasound may be appropriate if radiographs are noncontributory and there is suspicion of concomitant rotator cuff pathology 5
First-Line Conservative Management
- Oral anti-inflammatory medications (NSAIDs) should be initiated to reduce pain and inflammation 6, 7
- Intra-articular corticosteroid (IACS) injections provide significant pain relief and improved range of motion in the early painful (freezing) stage 1, 2
- Physical therapy exercises targeted at improving range of motion should be started early in the treatment process 1, 8
- The combination of IACS injections with physical therapy has stronger support in the literature for improving shoulder pain, range of motion, and function than either treatment alone 1, 6
Second-Line Interventions
- If no improvement occurs after 6-12 weeks of first-line treatment, consider:
Surgical Management
- Surgical intervention should be considered if conservative management fails after 3-6 months 2
- Arthroscopic capsular release is preferred over manipulation under anesthesia to avoid complications of "blind intervention" 6
- Open capsular release may be considered in severe recalcitrant cases 6

Common Pitfalls to Avoid
- Delaying treatment, which may lead to prolonged disability and decreased function 2
- Overly aggressive physical therapy in the early painful phase, which can worsen symptoms 8
- Failing to rule out other shoulder pathologies that may mimic adhesive capsulitis, such as rotator cuff tears or glenohumeral osteoarthritis 5, 7
- Not recognizing that patients with diabetes or thyroid disease are at higher risk and may have more refractory symptoms 7
