Abstract:
Objective:To compare the difference in clinical efficacy between a free wrist crease flap pedicled with superficial palmar branch of the radial artery flap (SPBRAF) and a traditional free toe flap (TFTF) in reconstruction of hand soft tissue defects, and to provide reference for the treatment of small-to medium-sized hand soft tissue defects.Methods:Data of 37 patients who received hand surgery in Department of Hand Surgery, No.971 Hospital of the PLA Navy from December 2016 to December 2019 for small-to medium-sized hand soft tissue defects were retrospectively studied. Among the 37 patients, there were 32 males and 5 females, aged between 18 and 65 years old, with 41.5 years old in average. According to the reconstructive surgical procedure, patients were divided into SPBRAF group (22 cases) and TFTF group (15 cases). Regular follow-ups were conducted after surgery. The difference in curative effect at the last follow-up between the 2 groups was evaluated by the comparison of data acquired in follow-up. SPSS 25.0 was used to analyse the data statistically. The evaluation indicators included flap survival, long-term recovery of flap, recovery effect at donor site, total active movement(TAM) of the affected digit, time of hospital stay and the time return to work. P<0.05 was considered a statistically significant. Results:All free flaps survived. All patients were entered 6-18 (mean, 10) months of postoperative follow-up to comprehensively evaluate the therapeutic effect. According to the Evaluation Trial Standards of Upper Limb Partial Function of Hand Surgery of Chinese Medical Association, in the SPBRAF group, 20 flaps were found in excellent, and 2 in good; in the TFTF group, 14 flaps were found in excellent, 1 in good. There was no statistical difference between the 2 groups( P>0.05). The colour, texture and thickness of flaps between the 2 groups were either in excellent or good. There was no statistical difference between the 2 groups( P>0.05). TPD in the TFTF group (5-6 mm) was better than that in SPBRAF group (6-7 mm) with statistical difference between the 2 groups ( P<0.05). Texture at donor sites between the 2 groups was either in excellent or good ( P>0.05). In terms of appearance, sensation and recovery time of donor site, it was found that the SPBRAF group(mean, 6 weeks) was significantly better than those in the TFTF group(mean, 8 weeks) and there was statistical difference between the 2 groups ( P<0.05). In terms of recovery of TAM in single-digit, excellent or good were shown in both groups and there was no statistical difference between the 2 groups ( P>0.05). In terms of hospitalisation and time for return to work, the SPBRAF group(mean, 8 days and 17 weeks) was significantly better than that of TFTF group(mean, 12 days and 24 weeks), and there was statistical difference between the 2 groups ( P<0.05). Conclusion:SPBRAF has an ideal effect on reconstruction of small-to medium-sized hand soft tissue defects in hand. Although the flap is still inferior in sensation and appearance compared with the TFTF, the advantages in terms of donor site recovery, patient satisfaction of the donor site and reduced time of hospitalisation and return to original work are more obvious. SPBRAF provides a good complement to surgical procedures reconstructing a digit defect.
