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.
ABSTRACT
Objective To investigate the outcome of the finger reconstruction using one toe transfer to repair the tissue defects of two fingers at the same time. Methods Two fingers joint tissue missing and finger defect of 8 fingers in 4 cases were reconstructed with dissociative transplants harvested from two parts of the same toe at the same time.Using the paratelum of the second toes reconstructed the indicis paratelum or finger tip,and using the proximal interphalangeal joint of the second toes repaired the proximal interphalangeal joint's tissue defects of the middle finger at the same time in 2 cases.Using the distal interphalangeal joint and the proximal interphalangeal joint of one second toe reconstructed the proximal interpha langeal joints of the index finger and the middle finger in 1 case.Using the proximal interphalangeal joint and the metatarsophalangeal joint of one second toe reconstructed the metacarpophalangeal joints of the index finger and the middle finger in 1 case. Results All the transplants survived.The patients were followed-up from 2 months to 46 months postoperatively.The function and shape of 2 resconstruction fingers were excellent as assessed with Criterion on Functional Evaluation on Finger Reconstruction issued by Chinese Society of Hand Surgery.Five resconstruction fingers were good.One resconstruction finger was fire. Conclusion For some appropriate cases with the tissue defects of 2 fingers such as the finger's paratelum,the interphalangeal joint or the metacarpophalangeal joint,this operated technique was a good method.
ABSTRACT
Objective To summarize and investigate the therapeutic effects of reconstruction of contracture of the first web space with snuff-box flap. Methods Eighteen patients with contracture of the first web space were treated by snuff-box flap. The width and the angle of the first web space was 19 mm and 20°on average. According to the first web space skin defects, the flap designed to nasopharyngeal fossa centers as rotation point, the radial line when the forearm in the neutral position as the axis. Results The followedup for 5-26 months revealed that 17 flaps had a success, but 1 case was partly necrosis. The width of the first web space was augmented by an aveage of 45 mm, the angle of the first web space was augmented by an average of 50°. Conclusion It is ralatively simple and reliable to repair the contracture of the first web space using the snuff-box flap.
ABSTRACT
@#Objective To report the results of aesthetic reconstruction of distal finger or middle-distal finger segment with transplant harvested from 2nd, 3rd or 4th toe. Methods In a series of 108 cases of distal finger or middle-distal finger segment defect, 141 fingers were reconstructed with transplants harvested from 2nd, 3rd or 4th toe according to the outward appearance of donor toe. The blood-supply was restored by anastomosis of digital artery and vein. In first-stage reconstruction, refinement of outward appearance was applied in doner toe if the toe pulp is bulky or middle part of toe was relatively thinner. Results One hundred and forty fingers survived. The successful rate was 99.3%. Among them, 81 patients had been followed up from 1 to 10 years (mean 3.5years) postoperatively. 61 cases were graded to be excellent and 16 eases good as assessed with Criterion of Functional Evaluation on Finger Reconstruction issued by Chinese Society of Hand Surgery. Conclusion For aesthetic reconstruction of distal finger or middle-distal finger segment, the 2nd toe is usually considered to be donor of first choice. In case the outward appearance of 2nd toe was inferior to that of 3rd or 4th toe, the 3rd or 4th toe should be chosen for better result. In some cases, revisional aesthetic surgery were necessary to refine the outward appearance in first-stage reconstruction.
ABSTRACT
Objective To explore small size toe tissue flap for aesthetic reconstruction of the thumb and / or finger. Methods Six kinds of small size toe tissue transplants had been applied in repairing skin-bone-joint composite tissue defects of the thumb or finger in 74 cases. Results Among 83reconstructed flaps of the 74 patients, 81 flaps survived completely. Follow-up examination made three to forty-eight months postoperatively showed that the outward appearance were excellent in most cases. The function of the thumbs or fingers were good. The donor feet can walk normally with no pain. Conclusion A variable combinations of toe tissues including skin, soft tissue, bone and joint can be harvested to form a lot of small size transplants for refined aesthetic reconstruction of thumb and finger. The functional and aesthetic results are good and the treatment course is shortened.
ABSTRACT
Objective To expore the method of clinical application and the final result of pedicled flap supplied by radial osteo cutaneous branch of anterior interosseous artery Methods Basing on the anatomic basis that the osteo cutaneous and myocutaneous branches of the anterior interosseous artery have constant collateral anastomoses which can give forth a large size dorso radial flap on dorsum of the forearm Four cases of skin defect of first web had been reconstructed by this flap Results All 4 cases were successful with good functional and cosmetic results Conclusion Reconstruction with dorso radial flap of forearm is simple,reliable procedure which bring minimum trauma to the patient and is an ideal alternative operation
