This study aims to compare the efficacy and outcomes of perineural injection with 5% dextrose, local ozone and glucocorticoid injection in the management of carpal tunnel syndrome.

Carpal Tunnel Syndrome is one of the most common peripheral entrapment neuropathies caused by compression of the median nerve within the carpal tunnel. This condition manifests as pain, numbness, tingling, and weakness, primarily in the thumb, index, and middle fingers. The condition significantly impairs daily activities and diminishes the quality of life, often prompting patients to seek medical interventions . The pathophysiology of Carpal Tunnel Syndrome involves increased pressure within the carpal tunnel, leading to ischemia and dysfunction of the median nerve. Risk factors include repetitive wrist motions, systemic diseases like diabetes and rheumatoid arthritis, obesity, and hormonal changes during pregnancy .Early identification and treatment are essential to prevent irreversible nerve damage and functional impairment . Traditional management strategies for Carpal Tunnel Syndrome vary depending on the severity of symptoms. Conservative approaches, including wrist splinting, activity modification, and physical therapy, are typically recommended for mild to moderate cases . However, these methods often provide limited relief, and invasive treatments, such as corticosteroid injections or surgical decompression, may be required for advanced or refractory cases . In recent years, less invasive alternatives like perineural injection therapies have gained attention as promising options for carpal Tunnel Syndrome management . These therapies aim to reduce inflammation, relieve nerve compression, and promote tissue healing. The substances under investigation in this study include 5% dextrose, ozone, and glucocorticoids . Dextrose acts as a neuroprotective and anti-inflammatory agent by modulating nociceptive pathways .It promotes tissue repair through proliferative and regenerative mechanisms, reducing local pain and inflammation. While hyperosmolar dextrose solutions may stabilize nerve function by deterring the release of pro-inflammatory cytokines, the effects of Dextrose 5% are primarily attributed to its role as an energy source for neuronal cells and its involvement in metabolic processes associated with neural repair. Ozone, when used in medical-grade concentrations, exhibits potent anti-inflammatory and antioxidative effects. It neutralizes reactive oxygen species, reduces oxidative stress, and improves local oxygenation. These effects can enhance nerve function and reduce ischemia within the carpal tunnel . Glucocorticoids, such as dexamethasone, exert their effects by suppressing local inflammatory responses. They inhibit the release of pro-inflammatory mediators, such as prostaglandins and cytokines, providing rapid symptom relief. However, their short-term efficacy and potential for symptom recurrence necessitate careful evaluation. Despite the availability of these treatments, there is a lack of robust comparative studies to determine their relative efficacy and outcomes. This research aims to fill this gap by comparing the effectiveness of perineural injections with 5% dextrose, local ozone, and glucocorticoids in the management of Carpal Tunnel Syndrome. Primary outcomes • Evaluation of electrodiagnostic parameters (median nerve distal motor latency and sensory conduction velocity) at 3 months. Secondary outcomes * Evaluation of analgesic efficacy of Dextrose 5%, Ozone and Glucocorticoid local injection in carpal tunnel syndrome via assessment of Visual Analog Scale pain scores after injection by 1 and 3 months. * Evaluation of Analgesic drugs requirement.
