Repair of Multiple Finger Defects Using the Dorsal Homodigital Island Flaps

Not Applicable

Completed

• Conditions: Finger Injuries; Soft Tissue Injuries
• Interventions: Procedure: Soft tissue coverage

• Registration Number: NCT01767727
• Lead Sponsor: The Second Hospital of Tangshan

Brief Summary

Multiple finger defects are common in hand trauma and result in functional disability. These injuries are often complex and severe, and thus reconstructive alternatives are limited. In this study, we use the dorsal homodigital island flaps, based on the dorsal branch of the digital artery, for reconstruction of multiple finger defects. At the final follow-up, we would evaluate the efficacy of this technique.

Detailed Description

At final follow-up, sensation of the flap and the donor site would be assessed using static two-point discrimination and Semmes-Weinstein monofilament testing. The range of motion of the proximal interphalangeal joint and the distal interphalangeal joint of the injured finger is measured by a goniometer. The cold intolerance of the injured finger is measured using the self-administered Cold Intolerance Severity Score questionnaire that is rated into mild, moderate, severe, and extreme. The pain of the injured finger and the donor site is given subjectively by the patient using the visual analogue scale, which ranges from 0 to 10 cm and groupes into mild (0-3 cm), moderate (4-6 cm) and severe (7-10 cm).

Arm && Interventions

Group	Intervention	Description
Surgical flap	Soft tissue coverage	Surgical flap is based on the dorsal branch of the digital artery, and is used for soft tissue coverageof multiple finger defects.

Primary Outcome Measures

Name	Time	Method
static two-point discrimination	postoperative 18-24 months	The test points are at the center of the flap.Each area is tested 3 times with a Discriminator. We stopp at 4 mm as a limit of two-point discrimination and consider this normal.

Secondary Outcome Measures

Name	Time	Method
Cold intolerance of the injured finger	Postoperative 18-24 months	The cold intolerance of the injured finger was measured using the self-administered Cold Intolerance Severity Score questionnaire that was rated into mild, moderate, severe, and extreme.
