ABSTRACT

Carpal tunnel syndrome represents the most frequent cause of nerve compression which is caused by an increase in compartmentalpressure that compresses the median nerve. A study was performed in 42 patients: open surgery (group A) or endoscopic surgery (group B). After comparing both techniques, the endoscopic handling showed better short term results, such as better muscular strength two weeks after surgery (p = 0.001) and four weeks later (p = 0.026). In the pain scale evaluation there was a change from severe to moderate at two weeks (p = 0.005) and to mild at one month (p = 0.131). 71% of the patients showed a change in disability from high to moderate at two weeks (p = 0.018), while 67% continued with moderate disability and 33% low disability at one month (p = 0.027). Tinel test was negative at two weeks in 71% (p = 0.011) and in 86% of patients at one month (p = 0.022). 71% of patients showed negative Phalen test at two weeks and 81% at fourth weeks, even though we did not find statistical relevance among the groups (p = 0.063 and p = 0.218). Three months later both tests were negative in 100% of the patients of each group. Surgical scar length was shorter with the endoscopic surgery (p = 0.0001). We concluded that both procedures represent useful tools in the surgical handling of carpal tunnel syndrome. At three months after surgery both procedures offer an adequate muscular strength, improvement of the disability grade and the pain become barely noticeable. The endoscopic surgery resulted in shorter surgical scars that can be expressed as a lower rate of recurrence with a better aesthetic result.
