简要总结
Multiple digital injuries are often complex and severe, and the commonly used local and regional flaps may not be feasible. The authors reconstruct soft tissue defects of the fingers using the dorsal digito-metacarpal flap and evaluate the efficacy of this technique.
详细描述
At final follow-up, we measure the sensibility of the flaps using the static 2-point discrimination test. The Static 2-point discrimination test determines the minimal distance at which a subject can sense the presence of two needle. The modified American Society for Surgery of the Hand guidalines are used to stratify discriminator measurements(excellent <6 mm, good 6-10 mm, fair 11-15 mm, poor >15 mm). Each area is tested 3 times with a Discriminator (Ali Med, Dedham, MA). Two out of 3 correct answers are considered proof of perception before proceeding to another lower value. We stopp at 4mm as a limit of 2PD and consider this normal. The measurements are performed at a single time point at final follow up.

入选标准
- •the injured and adjacent fingers are unable to be used as the donor due to multiple digital injuries
- •a soft tissue defect > 1.5 cm in length with exposed bone or tendon
- •the reverse DMA flap may not be appropriate for tissue reconstruction due to the concomitant injuries or due to the limitation of the rotation arc
- •a patient between 15 and 60 years of age
排除标准
- •concomitant injuries involved all the finger that precluded their use as donor sites
- •a defect less than 1.5 cm in length
- •injuries to the course of the vascular pedicle

主要结局
The Static 2-point discrimination test
时间窗: 18 to 24months
The Static 2-point discrimination test determines the minimal distance at which a subject can sense the presence of two needle. The modified American Society for Surgery of the Hand guidalines are used to stratify discriminator measurements(excellent \<6 mm, good 6-10 mm, fair 11-15 mm, poor \>15 mm). Each area is tested 3 times with a Discriminator (Ali Med, Dedham, MA). Two out of 3 correct answers are considered proof of perception before proceeding to another lower value. We stopped at 4mm as a limit of 2PD and considered this normal. The measurements are performed at a single time point at final follow up.
次要结局
- Patient satisfaction(18 to 24 months)
