In the treatment of adhesive capsulitis, conservative treatment usually gives successful results, and steroid injection is an effective method that is frequently preferred among conservative treatment modalities. However, many controversial issues have not yet been clarified in the literature, such as the location of the injection, whether into the glenohumeral joint or around the coracohumeral ligament where the most radiological findings are detected.

Purpose:

To compare the intra-articular steroid administration with the extra-articular one; around the coracohumeral ligament in patients with adhesive capsulitis.

Method:

Ethics committee approval was obtained for the study. Patients who were diagnosed with adhesive capsulitis in the orthopedic outpatient clinic were included. Diagnosis was confimed by physical examination and Magnetic Resonance Imaging (MRI) findings. Patients with radiological finding of any tear in the rotator cuff or long head of biceps tendons were excluded. Only patients in the freezing or frozen stage of the disease were included. Patients who were previously treated with the diagnosis of adhesive caspulitis or who received any injections to the shoulder joint were not included in the study. Included patients were randomly divided into two groups according to age, sex, duration of complaint, concomitant diabetes mellitus (DM) disease and clinical stage of the disease. For randomization, stratified randomization was applied according to the information obtained from the outpatient clinic. While patients in group 1 received an anterior extra-articular steroid injection under USG guidance, patients in group 2 received posterior intra-articular steroid injection under USG guidance. A combination of 1 mL of triamcinolone acetonide (40 mg/mL) and 1 mL of prilocaine hydrochloride (2%) were injected to all patients. Patients were first evaluated before injection, than randomized to groups and prospectively followed up by an orthopaedic surgeon who was blinded to the groups. Evaluation was done for pain (visual analog scale score; VAS), functional status (American Shoulder and Elbow Surgeons score; ASES and Quick Disabilities of the Arm, Shoulder and Hand; Quick DASH), and active shoulder joint range of motion (ROM) angles at 1, 3, and 6 weeks after the injection. Means and standard deviations of were noted for each measurement period and each group. Improvements in each period between the groups and differences between the preinjection values and each follow-up period between the groups were analyzed using Ficher exact test, independent-samples t tests and Manova test. P < .05 was considered significant.

Inclusion Criteria:

• must be between the ages of 18-75
• clinically and radiologically confirmed adhesive capsulitis

Exclusion Criteria:

• Patients with a tear in any of the rotator cuff tendons
• Patients who have had steroid injections in the shoulder region before
• patients who have been treated with the diagnosis of adhesive capsulitis (except for oral non-steroidal anti-inflammatory drug therapy)
• Patients with a previous history of trauma-fracture-dislocation in the shoulder region

All the criteria specified and to be observed regarding the study will be transferred to the system in a timely manner and will be observed by the researchers outside the personal information of the patients.

There will be no time limitations on data monitoring
