Case Report: Photobiomodulation improves shoulder functionality after acute traumatic anterior dislocation associated with Hill-Sachs bone lesion’

Abstract

Photobiomodulation (PBM) has demonstrated positive effects on bone healing after fracture. This case report describes a skateboard-related shoulder anterior dislocation with Bankart and Hill-Sachs lesions. After a non-invasive reduction, the patient received conservative treatment with PBM. PBM was started on the accident day and continued daily for 30 days, followed by bi-weekly irradiation for 33 months. In the initial 30 days, the patient’s pain decreased, and the shoulder function was recovered with no pain, swelling, or bruising. On day 28, there was a reduction in edema compared to the initial injury and a full shoulder recovery for daily and sports activities. Physical examinations confirmed shoulder joint stability and the images at 33 months demonstrated Hill-Sachs lesion healing and significant Bankart lesion repair. In conclusion, PBM can induce recovery, alleviate pain, and facilitate functional rehabilitation. Additional clinical trials are required to validate the efficacy of this complementary therapy.
