Direct and Reversed Dorsal Digital Island Flaps: A Review of 65 Cases

March 28, 2014 updated by: The Second Hospital of Tangshan
Reconstruction of soft tissue defects in the fingers continues to be a challenge problem. The study reports reconstruction of small to moderate defects of the fingers with the direct and reversed dorsal digital island flaps and evaluates the results of the use of the flaps.The main outcomes are static 2-point discrimination and Semmes-Weinstein monofilament scores of the flap and joint motion.

Detailed Description

At final follow-up, sensory restoration of the flap is measured using the static 2-point discrimination (2PD) test and Semmes-Weinstein monofilament (SWM) test. Active motion of the joints is measured using a standard hand goniometer. For the direct DDIF, total active motion is calculated as the sum of degrees of active flexion of the interphalangeal and the metacarpophalangeal joints subtracted from the degrees of extension deficit. For the reversed DDIF, total active motion of the donor finger is calculated as the sum of degrees of active flexion of the proximal and distal interphalangeal joints subtracted from the degrees of extension deficit.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: Dorsal digital island flap
The flap is used to cover the soft-tissue defects of the fingers.
Procedure: Direct and reversed dorsal digital island flap
The direct dorsal digital island flap is used to cover the defects of adjacent fingers. The reversed dorsal digital island flap is used to cover the defects of the same fingers.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Static 2-point discrimination test
Time Frame: 16 to 24 months
The test points are at the center of the flap. Each area is tested 3 times with a Discriminator (Ali Med, Dedham, MA). We stop at 4mm as a limit of static 2-point discrimination test and consider this normal.
16 to 24 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Total active motion
Time Frame: 16-24 months
Active motion of the joints is measured using a standard hand goniometer. For the direct DDIF, total active motion is calculated as the sum of degrees of active flexion of the interphalangeal and the metacarpophalangeal joints subtracted from the degrees of extension deficit. For the reversed DDIF, TAM of the donor finger is calculated as the sum of degrees of active flexion of the proximal and distal interphalangeal joints subtracted from the degrees of extension deficit.
16-24 months
