简要总结
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.
详细描述
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).

入选标准
- •a patient who had separate soft tissue defects in different fingers in same hand;
- •the defect ≥ 1.5 cm and ≤ 3.5 cm in length;
- •local tissue near the defect is uninjured; and
- •a patient between 15 and 60 years of age.
排除标准

研究组 & 干预措施
Surgical flap
Surgical flap is based on the dorsal branch of the digital artery, and is used for soft tissue coverageof multiple finger defects.
干预措施: Soft tissue coverage (Procedure)
结局指标
主要结局
static two-point discrimination
时间窗: 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.
次要结局
- Cold intolerance of the injured finger(Postoperative 18-24 months)
