Abstract

Between February 2012 and March 2014 10 patients were admitted to the Affiliated Hospital of Nantong University for surgery due to a thumb tip defect. Nine of these patients were male and one was female and there were 7 cases of left thumb defects and 3 cases of right thumb defects. The surgical procedures followed were first, modification of the flap tail to an equilateral triangle, which facilitated pedicle suturing of soft tissue defects, caused mild tension and effectively reduced venous disorders, and second complete opening of the flap pedicle to the soft tissue defects at the tunnel. All patients were followed up at 6 and 12 months after surgery. Grip and pinch strength were measured 6 and 12 months after surgery. Static two‑point discrimination testing of the modified flap showed minor differences from the uninjured hand. Post‑surgery grip and pinch strength were restored to approximately 85% of the level of that in the uninjured hand. The modified dorsoulnar artery pedicle flap provided excellent thumb tip defect coverage and is an effective and safe technique for the restoration of grip and pinch strength to the hand after the repair of a thumb tip defect.
