Abstract

in English, Chinese

Objective:

To investigate the effectiveness of modified free medial plantar flap with preserved abductor hallucis for repairing cicatricial contracture deformity of palm.

Methods:

Between January 2012 and July 2017, a modified free medial plantar flap with preserved abductor hallucis was used to repair 9 cases of cicatricial contracture deformity at the palm. There were 7 males and 2 females with a median age of 23 years old (range, 15-40 years). The duration of cicatricial contracture was 4-23 years (mean, 9 years). In addition, 3 cases had combined stiffness of finger joints, 2 cases of tendon exposure, and 2 cases with exposed tendon and nerve. The range of flap was 4.5 cm×4.0 cm to 8.0 cm×6.0 cm. The vessel pedicle of the flap was 7-8 cm in length, with an average length of 7.5 cm. Grafting and repairing were performed with full-thickness skin graft from the ilioinguinal region in the donor site.

Results:

All flaps and skin grafts survived after operation, and all wounds healed at first intention. All 9 patients were followed up 5-22 months (mean, 10 months). The flap exhibited smooth appearance and soft texture, which was similar to that of the normal skin around. The recovery time of dermal sensation was 5-12 months (mean, 9 months). At last follow-up, the flap recovered to level S 4 in 5 cases, level S 3 in 3 cases, and level S 3 in 2 cases. The two-point discrimination was 6.0-10.0 mm (mean, 8.5 mm). According to the assessment of the upper limb function issued by the Hand Surgery Society of Chinese Medical Association, the hand function was excellent in 5 cases, good in 2 cases, and fair in 2 cases. Additionally, the abduction and flexion activities of the great toe of the donor foot were not affected, and the skin grafting area was slightly colored.

Conclusion:

The modified free medial plantar flap for repairing cicatricial contracture deformity of palm has such advantages as no impact on abductor hallucis, small damage of the donor area, improved survival rate of skin grafting, and the unaffected function of the donor foot.
