Background: Carpal Tunnel Syndrome(CTS) is characterized by complications such as pain, paresthesia, and numbness in the fingers. There are some surgical therapies for management of severe carpal tunnel, but differences exist between the treatments available for creating the opposition. Therefore, the current study was conducted to compare the effect of modified Camitz and BRAND techniques on thumb opposition in patients with severe CTS.
Methods: This clinical trial study was carried out in the Alzahra and Kashani hospitals in Isfahan province, Iran from 2014 to 2018. Subjects included 40 patients with severe CTS who had the indications for opponensplasty surgery based on inclusion and exclusion criteria. The patients were divided into two parallel groups of modified Camitz and BRAND. Quick DASH-9 score, Kapandji score, pulp and side pinch and pronation angle were assessed in the patients before and after surgery.
Results: The results of the study showed that , Quick DASH-9 score, Kapandji score, pulp and side pinch and pronation angle significantly improved post-operative compared to pre-operative (P<0.05). But, there were no significant differences in the mentioned variables between both groups pre and post-operative (P>0.05, for all the studied variables). There was not any complications in both groups after the surgery.
Conclusion: The findings of the present study demonstrated that, both Modified Camitz and BRAND techniques are effective and safe techniques, yielding high improvement and no serious complications, and they can be considered for treatment of patients with severe CTS.
