ABSTRACT
Objective:To explore the surgical method and clinical effect of harvesting 2 ipsilateral free pedicled perforator flaps from a single donor site of superficial peroneal artery in reconstruction of 2 defects in same or adjacent digits.Methods:From November 2017 to August 2021, 12 patients with 2 defects in same or adjacent digits were treated in the Department of Hand Surgery, Suzhou Ruihua Orthopaedic Hospital with 2 ipsilateral free pedicled perforator flaps from a single donor site of superficial peroneal artery. Among the patients, 1 had the defect in dorsal and palmar of index finger, 1 in thumb and index finger, 6 in index and middle fingers, 3 in middle and ring fingers, and 1 in ring and little fingers. The size of digit defects was 1.5 cm×0.8 cm-6.0 cm×3.5 cm. The size of flaps was 2.0 cm× 1.2 cm-8.0 cm×4.0 cm. All the patients were included in postoperative monthly follow-up to assess the recovery of recipient and donor sites at outpatient service, by telephone or WeChat.Results:All 24 flaps in 12 patients survived without vascular compromise and achieved 100% of survival rate. The follow-up period ranged from 4 to 18 months, with an average of 10 months. Six patients were treated with additional flap thinning and plastic surgery at 4 months after the primary surgery due to slightly bloated flaps. Otherwise, all the flaps in the recipient site had neither pigmentation, obvious hyperplasia nor scar pain. All flaps gained the protective sensations, however the assessment of TPD was not conducted. The flaps were wear-resist and had no ulceration. The texture of the flaps was soft with good elasticity, and the flap did not turn to purple or swelling when in cold. The functional recovery of 23 digits in 12 patients was evaluated according to the total active mobility (TAM) of the digits. It achieved excellent in 3 digits, good in 15 digits, and fair in 5 digits, with an excellent and good rate of 78.26%. A linear scar appeared at the donor site without obvious hyperplasia or scar pain. There were normal sensations around the scar and at the digit-tips. The blood supply to the digit-tips was normal.Conclusion:Harvest of multiple free pedicled perforator flaps from a single donor site of superficial peroneal artery is an effective method in reconstruction of 2 defects in same or adjacent digits at the same time. It has advantages of being a simple surgery procedure by sacrificing only one donor site. It achieves a minimal damage to the donor site and a reliable blood supply of the flap.
ABSTRACT
Objective:To explore the surgical procedure and clinical effect of the free Flow-through superficial peroneal artery flap for repairing the digit injury with defect of proper palmar digital artery.Methods:From June, 2015 to December, 2019, free Flow-through superficial peroneal artery flap was used to repair the digit injury and to bridge the proper digital artery in 7 digits of 7 patients. There were 2 thumbs, 3 index fingers and 2 middle fingers. The size of defects on digits ranged from 2.5 cm×3.0 cm to 5.0 cm×7.0 cm. The defects of digit proper artery were 1.0 to 3.0 cm. The size of flaps was from 3.0 cm×3.5 cm to 5.5 cm×8.0 cm. The donor areas of the flap were directly sutured or covered with skin graft. Postoperative supportive treatments were given, such as infection prevention, antispasmodic, anticoagulant, analgesia and fluid infusion. The patients were kept in bed for 1 week after surgery. Monthly follow-up review were conducted and the patients were kept with the rehabilitation exercises under medical guidance.Results:All the patients entered postoperative followed-up for 6 to 18 months, with an average of 8 months. All flaps survived without any adverse event. All wounds achieved stage-one-healing. The flaps appeared in good colour, texture, elasticity and the plumps of the digit without obvious bloating. There was no obvious swelling and atrophy of the digits. The skin temperature was normal. According to the Standard for Evaluation of Upper Limb Function by the Hand Surgery Society of Chinese Medical Association, 3 digits were excellent and 4 were good. There was no obvious scar at the donor site of shank. The donor site had a good appearance and the limb function was not affected.Conclusion:The free Flow-through superficial peroneal artery flap is an ideal material to repair the defect of digit with the defect of proper digital artery. It has the advantages of simple surgical procedure, reliable blood supply and satisfactory appearance. The defect of proper digit artery can be repaired at the same time of the surgical procedure. The blood supply, appearance and function of the digits could be well recovered and the donor site is not affected.
ABSTRACT
Objective To explore the surgical technique and clinical effects of free anterolateral thigh flaps with fascia lata for repair of dorsal tendon and soft tissue defect of ophisthenar.Methods From February,2014 to July,2016,dorsal tendon and soft tissue defect of ophisthenar in 13 cases was repaired by free anterolateral thigh flaps with fascia lata.The area of soft tissue defect was 5.0 cm×6.0 cm-9.0 cm×12.0 cm.Extensor tendon defect and bone exposure occurred in all cases.The area of flap was 6.0 cm×7.0 cm-10.0 cm×13.0 cm,while the area of anterolateral thigh flap was 3.0 cm×4.0 cm-6.0 cm×8.0 cm.The regular post-operatively followed-up was performed.Results All flaps survived.The donor sites healed well without skin graft.The followed-up time was 6-36 months with the average of 13 months.The appearance of the flap was good.The color and texture of flaps was similar to the dorsal skin of ophisthenar.Three female patients who were not satisfied with the flap appearance received the revision and the results were satisfactory.The activity of finger flexion and extension was satisfactory.All patients walked well without difficulty.According to the Upper Extremity Functional Evaluation Standard set up by Hand Surgery Branch of Chinese Medical Association,the function recovery result was excellent in 8 cases,good in 4 cases,and poor in 1 case.Conclusion It is a good method to use the free anterolateral thigh flaps with fascia lata to repair of dorsal tendon and soft tissue defect of ophisthenar.
ABSTRACT
Objective@#To explore the effects of multiple free homologous superficial peroneal artery perforator flaps of crus for repair of multiple hand wounds.@*Methods@#From November 2017 to December 2018, eight cases with eighteen hand wounds were hospitalized in our unit. Among them, wounds were distributed in the forefinger and middle finger in four cases, wounds were distributed in the middle finger and ring finger in two cases, wounds were distributed in the forefinger, middle finger, and ring finger in one case, and wounds were distributed in the middle finger, ring finger, and little finger in one case. The area of skin defect ranged from 1.5 cm×0.8 cm to 4.0 cm×3.0 cm. There were 4 males and 4 females, aged 34-62 years. Wounds of six cases were repaired by two free superficial peroneal artery perforator flaps from homolateral crus, and those of two cases were repaired by three free superficial peroneal artery perforator flaps from homolateral crus. Superficial peroneal artery and its accompanying vein of flap were anastomosed by end to end with digital artery and palmar or dorsal subcutaneous vein of recipient site during the operation. The area of flap ranged from 2.5 cm×1.2 cm to 5.0 cm×4.0 cm. No nerve was harvested during the operation, and donor site was sutured directly. The survival of the flaps and the healing of donor sites were recorded. During follow-up, the recovery of donor and recipient sites was observed.@*Results@#All flaps survived well, donor site healed well. No vascular crisis occurred. Follow-up for 4 to 12 months showed that the appearance of flap was satisfactory with good color, texture, elasticity, and function. Protective sensation of recipient site was recovered. Five months after operation, flap of finger pulp in one case was swollen slightly with two-points discrimination of 10 mm, which received the thinning surgery. Obvious scar formation was not observed in donor site of crus. The appearance of the donor site was good without functional damage.@*Conclusions@#The application of multiple free homologous superficial peroneal artery perforator flaps of crus to repair the multiple hand wounds has advantages of easy acquisition, easy operation, little effect on donor sites, and satisfactory clinical effects.
