Ozone Injection for Shoulder Impengement Syndrome

Clinical and Functional Outcomes of a Single Dose Ozone, Three Doses of Ozone and Corticosteroid Injection in Patients With Shoulder Impingement Syndrome

Ozone injection has lately been utilized as a safe alternative to corticosteroids in the management of musculoskeletal diseases with fewer side effects. This study aimed to compare the effectiveness of a corticosteroid, single dose and three doses of ozone injection in shoulder impingement syndrome (SIS).

A hundred and eight SIS patients were divided into three groups and underwent subacromial injections in this prospective study. Group 1 received a single dose (n:36), group 2 (n:36) received three doses of ozone injection (n :36). Group 3 (n:36) was treated with a corticosteroid injection. Patients were evaluated using the visual analog scale (VAS) and Constant Murley Score (CMS), pre-injection and at 4 weeks and 12 weeks.

Inclusion Criteria: patients older than 18 years with shoulder pain lasting for more than three months, pain severity more than 5/10 on Visual Analog Scale (VAS), and diagnosed with SIS according to clinical examination and magnetic resonance imaging (MRI), were enrolled in this randomized clinical study.
