About this trial

This is an interventional treatment trial for Infection Wound focused on measuring defect;, dorsal branch of the proper digital nerve;, proper digital nerve;, finger sensory reconstruction.

Eligibility Criteria

16 Years - 55 Years (Child, Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • an infective wound with exposed bone or tendon in the finger;
  • soft tissue defect involving proximal half of the middle phalanx, the proximal phalanx, or both;
  • associated digital nerve defect 1 to 4 cm in length;
  • single or double nerve defects; and
  • simultaneous repair of nerve and soft tissue defects.

Exclusion Criteria:

  • injury to the course of the pedicle or the donor site;
  • nerve defect less than 1 cm or larger than 4 cm in length;
  • occurrence of the defect in a region the flap is unable to reach, such as distal interphalangeal joint region, distal portion of the middle phalanx of the middle finger and the thumb;
  • no involvement of the digital nerve.

Arm Description

Simultaneous repair of the infected wound and digital nerve defect in the finger using a bipedicled nerve flap including nerve graft from the dorsal branch of the digital nerve.

Outcomes

Primary Outcome Measures

2-point Discrimination Test
The 2-point Discrimination Test determines the minimal distance at which a subject can sense the presence of two needles. The modified American Society for Surgery of the Hand guidelines were used to stratify Discriminator measurements (excellent <6 mm; good 6-10 mm; fair 11-15 mm; poor >15 mm. The test points were at the center of the radial or ulnar portion of the pulp. Each area was tested 3 times with a Discriminator (Ali Med, Dedham, MA). Two out of 3 correct answers were considered proof of perception before proceeding to another lower value. We stopped at 4 mm as a limit of 2PD and considered this normal. The assessments were performed at a single time point at the final follow up.

Secondary Outcome Measures

Semmes-Weinstein (SW) Monofilament Test
The test points were at the center of the radial or ulnar portion of the pulp. The donor site, i.e. radial- or ulnar-dorsal aspect of the middle phalanx of the donor digit, was also evaluated.

5. Study Description

Brief Summary
A combination of soft tissue and digital nerve defects in the finger results in sensory loss of the finger pulp. Reconstruction of these combined injuries is difficult. When the neurocutaneous defect is associated with wound infection, reconstructive alternatives are more limited. From July 2008 to May 2010, a retrospective study was conducted with 9 consecutive postinfection patients who had the neurocutaneous defect of the finger following trauma. The purpose of this retrospective study is to report repair of the complicated infected wound in the finger using the bipedicled nerve flap and to evaluate the efficacy of this technique.
Detailed Description
sensation of the flaps is assessed using static two-point discrimination (2PD) and Semmes-Weinstein monofilament (SWM) testing at final follow-up. The cold intolerance of the injured finger is measured using the self-administered Cold Intolerance Severity Score questionnaire that was rated into mild, moderate, severe, and extreme (0-25, 26-50, 51-75 and 76-100). Patients report their satisfaction with functional recovery of the injured finger according to the Michigan Hand Outcomes Questionnaire that was based on a 5-point response scale.

Intervention Type
Device
Intervention Name(s)
Nerve flap
Intervention Description
Based on the Teoh et al.'s technique, we combined the nerve graft into the bipedicled heterodigital arterialized island flap and used this composite flap tissue for reconstructing complicated infected wound in the finger.

The test points were at the center of the radial or ulnar portion of the pulp. The donor site, i.e. radial- or ulnar-dorsal aspect of the middle phalanx of the donor digit, was also evaluated.
Time Frame

Other Pre-specified Outcome Measures:

Pain
Description
Pain was given subjectively by the patient using the visual analogue scale (VAS). The VAS consists of a 10 cm line that was grouped into mild (1-3 cm), moderate (4-6 cm) and severe (7-10 cm).
