Clinical application of dorsal carpometacarpal reversed island flap with dorsal metacarpal nerve to reconstruct finger

To investigate the clinical effect of dorsal carpometacarpal reversed island flap with dorsal metacarpal nerve to reconstruct finger.Methods We designed the dorsal reverse carpal and metacarpal island flaps with nerve by using the adjacent two dorsal matacarpal arteries as blood-supply and applied the stand of bone and tendon in waste finger or the free iliac transplantation to reconstruct the every sensory finger.Results Eighten cases were survived completely,and the skin degloving injuries of the finger in 3 cases.The maximum of the flap was 9 cm by 8 cm.Patients were followed up 3 months to 2 years,7 weeks later pain sense of reconstructed finger was recovered.Sensation over S3 amounts to 89% of the digits.Two-point-discrimination of the digits was 5～10 mm.After the operation,the reconstructed finger obtained good appearance,the sensory recovery approach normally.The patients have ability to fulfil daily activities.Conclusion This methods has advantages as follow:simple and practical,high survival rate,low impairment,sensible and good appearance.7 refs,3 figs.
