ABSTRACT

Objective:

To investigate the effect of arterialised Flow-through venous flap with palmaris longus tendon in repairing dorsal digit composite tissue defect.

Methods:

From March, 2010 to December, 2018, 23 cases (23 digits) of dorsal digit composite tissue defect were repaired with arterialised Flow-through venous flap with palmaris longus tendon. There were 17 males and 6 females aged between 23 to 53 (average, 37.2) years old. Causes of injury 15 cases of strangulation, 5 of electric plane and 3 of thermal crush. Number of injured digit were 1 thumb, 11 index fingers, 9 middle fingers and 2 ring fingers. All of the injured digits had skin and extensor tendon defects with an area of 2.0 cm×1.8 cm-4.2 cm×2.6 cm, and the length of extensor tendon defect was 1.6-2.6 cm. One case had terminal and central tendon insertion defects and 5 suffered with terminal tendon insertion defect. Three cases were repaired by emergency surgery, and 20 were repaired by sub-emergency surgery. All donor sites were directly sutured. The shape, colour, texture, sensation, recovery of digit function and donor site appearance were followed-up at outpatient clinic.

Results:

The patients were followed-up for 8 to 23 (average, 11) months. The flap was soft, with mild pigmentation and recovery of protective sensation. The range of motion of the proximal and distal interphalangeal joints was 145°-170° (average,162.6°). According to Strickland hand function evaluation method, the results were excellent.

Conclusion:

The arterialised Flow-through venous flap with palmaris longus tendon is an ideal method in repair of the dorsal digit composite tissue defect.
