EFFECTIVENESS OF ULTRASOUND GUIDED LOCAL OZONE INJECTION VERSUS NORMAL SALINE INJECTION IN THE TREATMENT OF PATIENTS WITH CARPAL TUNNEL SYNDROME
Introduction: Carpal tunnel syndrome is the most common entrapment neuropathy in the upper limb. It is directly related to decrease in productivity due to work related disability. Various treatment options are available but there is no universally accepted treatment strategy. This study aimed to assess the therapeutic efficacy of ultrasound guided local ozone injection in the management of CTS and to compare it with a control.
Material & Method: This randomized controlled trial (RCT) was conducted in Department of PMR, RIMS Imphal. 32 patients with mild to moderate CTS were included in two parallel groups. Both the groups used a resting volar splint for 12 weeks. The intervention group received a single dose (4ml) of local ozone injection and control group received normal saline (4 ml) injection under ultrasound guidance. The outcome measures Visual analog scale (VAS) for pain, Symptom severity and functional status based on Boston carpal tunnel questionnaire were reassessed on 2weeks, 4weeks and 12 weeks after injection.
Results: All the outcome measures including VAS, Symptom severity and functional status improved significantly in both groups (p<0.05). But when compared between the groups; there was no statistically significant difference in improvement in the intervention group (Ozone)(p = 0.8) .No side effects were reported.
Conclusion: There is no added benefits with single dose of local ozone injection in the treatment of CTS, however further studies with multiple injection, higher dose and larger sample size is needed to confirm the results. Splinting can be considered as a mainstay in conservative management of CTS.
