Effects of Photobiomodulation on Functional Recovery of Proximal Humerus Fractures

The subjects selected for inclusion will be individuals of both genders treated at HMACN hospital, with isolated and closed proximal humerus fractures with displacement and surgical indication, undergoing open reduction and internal fixation (ORIF) with a locking angular stability plate for the proximal humerus (Neer 1070, Carrera et al., 2012; Petros, 2019), and meeting the following eligibility criteria. Individuals aged between 18 and 65 years, of both genders, with proximal humerus fractures classified as: Neer group III Neer group IV Neer group V AO/OTA subgroups A2 and A3 AO/OTA group B AO/OTA group C (only for patients under 55 years of age) Exclusion criteria: Individuals with pre-existing injuries or sequelae in the shoulder and shoulder girdle or motor deficits due to central or peripheral neurological injuries; Individuals with pathological fractures; Individuals who develop postoperative infection or implant loosening; Individuals with ipsilateral fractures in other regions of the limb; Individuals with neurovascular injuries causing sensory deficits at the injury site; Individuals with local or systemic conditions contraindicating surgical intervention or complicating postoperative recovery; Individuals with a history of photosensitivity; Individuals with neurological or psychiatric disorders; Individuals with proliferative or infectious skin lesions in the shoulder region receive LED light; Individuals who used anti-inflammatory drugs within five days before the trauma; Pregnant women; Individuals with surgical complications such as neurological or vascular injuries or fracture line extension during surgery will not meet the desired evolution pattern.
