Figure 3

Intraoperative photo of procedure. (a) Thenar racquet incision made with a 15 blade around the extra digit and down the radial side at the junction between the palmar and dorsal skin. (b) Disarticulated extra digit, measuring approximately 6 cm, excised after the extensor and flexor tendons were sharply released distally. (c) Radial facet of the radial thumb joint needing to be removed. Residual capsule was elevated off of the metacarpal base (origin of RCL), and a saw was then used to remove the articular surface and dorsal osteophyte. (d) Approximation of the tendinous insertion of the thenar musculature onto the dorsoradial capsule of the residual proximal phalanx using 3-0 FiberWire®.
