Brief Summary

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.

Conditions

Finger Injuries; Soft Tissue Injuries

Keywords

defect,; dorsal branch of the digital artery,; dorsal digital flap,; dorsal metacarpal artery flap.

Outcome Measures

Primary Outcomes (1)

• 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 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.

  18 to 24months

Secondary Outcomes (1)

Study Arms (1)

Surgical flap

EXPERIMENTAL

Dorsal digito-metacarpal flap is based on the dorsal digital artery and dorsal metacarpal artery.

Procedure: Dorsal digito-metacarpal flap

Interventions

Dorsal digito-metacarpal flap PROCEDURE

The dorsal digito-metacarpal flap is a vascular island flap based on the dorsal digital artery and dorsal metacarpal artery. It has a longer vascular pedicle and provides tissue coverage of similar quality as that of normal glabrous skin but not sacrifice the digital artery.

Eligibility Criteria

• Age: 15 Years - 55 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17), Adult (18-64)

You may qualify if:

• 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

You may not qualify if:

• 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
