Objectives/Interrogation: The purpose of this study is to determine if basilar thumb arthritis treatment using suture button suspensioplasty (SBS) is associated with better clinical and functional outcomes than treatment with Sigfusson-Lundborg ligamentoplasty (SLL).

Methods: We performed a retrospective study that included patients diagnosed with basilar thumb arthritis, submitted to surgical treatment with one of two techniques - SBS vs. SLL - and with a minimal follow up of 6 months. Surgical technique was chosen upon surgeon preference. Functional outcomes were compared using QuickDash Score (QDS) and pain was assessed with Visual Analogic Scale (VAS) in three diferent moments: before surgery and at 3 and 6 months after surgery. We also measured trapezial space before surgery and at last appointment.

Results and Conclusions: Twenty-six patients were included in this study. Thirteen were in SBS group and 13 in SLL group. Mean age was 63 (52-75) and no differences were found between groups (61,6 in SBS vs. 64,5 in SLL). Follow up was similar for both groups, 12,4 months for SBS and 12 months for SLL. Pain was 5,31 for SBS group and 5,46 for SLL group before suregy, which did was not significative (p>0,05). At 3 months, pain was statistically significative inferior in SBS group, 0,77 vs 1,77 (p=0,005). At 6 months, the differences between groups did not maintained (0,69 vs 0,92; p>0,05). QDS improved in both groups, from 36,01 to 12,76 in SBS group and from 37,77 to 12,93 no SLL group. In both times of measurement, we did not find differences between groups (p>0,05). Trapezial space decreased 28,1% in SBS group and 39,4% in SLL group which was statistically significant (p=0,012).

We reported no major complications and we registered two patients, one in each group, that sustained anesthesia in sensitive radial nerve area that resolved after nearly 3 months.

Basilar thumb arthritis can be a disabling condition. There are several surgical options for treatment of this condition and recently, SBS has grown in popularity, presenting as main advantage early mobilization. We think this is the main reason why, in our study, patients submitted to SBS refer less pain at 3 months than patients submitted to SLL.

We conclude that patients submitted to basilar thumb arthritis treatment with SBS recover faster than patients submitted to SLL, but this effect tend to disappear over time.
