Brief Summary

Soft tissue reconstruction in the finger continues to evolve. The dorsum of the finger is a reliable flap donor site in reconstructive hand surgery because of its similar quality to the original. The dorsal homodigital island flap can be used as a reliable alternative for reconstructing small to moderate defects of the fingers. In this retrospective study, the investigators would evaluate the efficacy of the technique for tissue reconstruction in different regions of the finger, with an emphasis on sensibility, pain and donor site morbidity.

Conditions

Soft Tissue Defect; Sensory Reconstruction of Digits; Multiple Digital Defects

Keywords

Soft tissue defect; dorsal branch of the digital artery; dorsal branch of the digital nerve; dorsal homodigital island flap

Outcome Measures

Primary Outcomes (1)

• Static 2-point discrimination test

  The test point is at the center of the flap. Each area was tested 3 times with a Discriminator (Ali Med, Dedham, MA). We stop at 4mm as a limit of 2PD and considered this normal.

  18 months to 24 months

Secondary Outcomes (1)

• Cold intolerance

  18 months to 24 months

Study Arms (1)

Surgical flap

OTHER

The dorsal homodigital island flap is a perforator type flap based on the DB, which uses the dorsal skin of the injured finger to provide soft tissue coverage for a volar defect.

Procedure: The dorsal homodigital island flap

Interventions

The dorsal homodigital island flap PROCEDURE

The dorsal homodigital island flap is used for tissue reconstruction in different regions of the finger.

Eligibility Criteria

• Age: 18 Years - 60 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• the soft tissue defect in one finger or in multiple fingers
