Comparison of the Effects Suprascapular Nerve Block and Intra-articular Shoulder Injection
Condition: Adhesive Capsulitis
MeSH terms: Bursitis
Study type: Interventional

Summary: 
      Objectives: In this study, we aimed to compare the efficacy of ultrasonography-guided
      suprascapular nerve block and intra-articular shoulder injection treatment in terms of joint
      range of motion, pain and functional status in patients with adhesive capsulitis (AC).

      Patients and Methods: 60 patients AC were included in our study. The patients were randomized
      into two groups according to the sealed envelope method. In the evaluation of the patients
      before the injection, age, gender, body mass index (BMI), occupation, education, duration of
      complaint, symptomatic side and dominant hand information were recorded. In the first group,
      2 ml of 40 mg triamcinolone acetonide and 4 ml of 1% lidocaine injection were mixed with the
      posterior approach method into the shoulder joint under the guidance of ultrasonography
      (USG). The second group underwent suprascapular nerve block (SSNB) injection with 2 ml of 40
      mg triamcinolone acetonide and 4 ml of 1% lidocaine under USG guidance. Shoulder range of
      motion (ROM), visual analog scale (VAS) scores and Shoulder Pain and Disability Index (SPADI)
      scores were compared before the injection, on the tenth day after the injection and at the
      third month after the injection.

      Conclusion: As a result of our study, although it was observed that both methods provided
      improvement in the treatment process, the significant improvement in the SSNB group indicates
      that it is a more reliable treatment method in AC treatment.
    

Detailed description: 
      Sixty patients AC who applied to our Orthopedics-Traumatology and Physical
      Medicine-Rehabilitation Outpatient Clinic were included in our study. The study was approved
      by the Hitit University Clinical Research Ethics Committee (Decision number:2023-56). A
      well-informed written consent was obtained from all participants according to the principles
      of the Declaration of Helsinki. Patients with an age range of 18-65 years, adapting to the
      treatment program to be applied, diagnosed with unilateral stage 2-3 AC, no shoulder trauma
      in the last 3 months, no shoulder injections, no bleeding disorder, no history of malignancy,
      inflammatory disease and stroke were included in the study. The patients were randomized into
      two groups according to the sealed envelope method. In the evaluation of the patients before
      the injection, age, gender, body mass index (BMI), occupation, education, duration of
      complaint, symptomatic side and dominant hand information were recorded. Injections were made
      to the patients by the physiatrist and anesthetist researcher under the guidance of Logiq V2
      portable USG device. In the first group, 2 ml of 40 mg triamcinolone acetonide and 4 ml of 1%
      lidocaine injection were mixed with the posterior approach method into the shoulder joint
      under the guidance of USG. The second group underwent suprascapular nerve block injection
      with 2 ml of 40 mg triamcinolone acetonide and 4 ml of 1% lidocaine under USG guidance. In
      addition, pendulum and ladder-finger exercises were given to both groups as a home exercise
      program. Shoulder range of motion (ROM), visual analog scale (VAS) scores and Shoulder Pain
      and Disability Index (SPADI) scores were compared before the injection, on the tenth day
      after the injection and at the third month after the injection.
