RESUMEN
Objective:To summarise the clinical application and results of superficial peroneal artery perforator flaps in tiled reconstruction of thumbs and fingers.Methods:From June 2020 to June 2022, 8 patients with finger or thumb defects (4 thumbs, 2 index fingers and 2 middle fingers) received digit reconstruction in the Department of Hand Surgery, Suzhou Ruihua Orthopaedic Hospital. Two thumbs (2 patients) were reconstructed with a free partial hallux nail flap combined with a free perforator flap of superficial peroneal artery and an iliac bone graft, 1 thumb was reconstructed with a free partial hallux nail flap combined with a free perforator flap of superficial peroneal artery, 1 thumb and 2 middle fingers were reconstructed with free perforator flaps of superficial peroneal artery combined with iliac bone grafts, and 2 index fingers were reconstructed with lobulated free perforator flaps of superficial peroneal artery. The sizes of the flaps were 1.8 cm×3.2 cm-4.0 cm×10.0 cm. Lengths of iliac crest were 1.5-4.0 cm. The donor sites were directly sutured in 5 patients, skin grafts in 2 and superficial peroneal artery perforator flap reconstruction in 1 patient. Postoperative observations included survival of the digits and healing of the bone grafts. Monthly scheduled postoperative follow-ups were conducted at outpatient clinics and via telephone or WeChat reviews, covering function and appearance of the reconstructed digits, impact on the function and appearance of donor sites as well as the satisfaction of patients.Results:All 8 reconstructed digits survived in one stage and all the 5 bone grafts healed at 3 to 4 months after surgery. The mean postoperative follow-up period was 10 months, ranged 4 to 20 months. The texture of the reconstructed digits was close to that of the recipient site and good in elasticity, without purplish while in cold, nor ulceration, obvious bloating and pigmentation. Sensation of the digit pulps was recovered to S 2 to S 3, and the sensation in touch, pain and temperature were restored. TPD was not checked. There was no noticeable hyperplasia nor pain in the recipient and donor sites. There was no obvious hyperplasia or pain at the donor sites for the hallux nail flap, and the skin grafts or flaps in the donor sites survived well without ulceration or pain and the function of the donor feet were not affected. Functions of the reconstructed digits were assessed according to the Functional Assessment Criteria for Thumb and Finger Reconstruction of the Society for Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, 4 patients achieved in excellent and 4 in good. According to the University of Michigan Hand Profile Questionnaire (MHQ), patient satisfaction was found very satisfied with 4 patients and satisfied with the other 4 patients. Conclusion:The superficial peroneal artery perforator flap has advantages of thin and large area with pleasant texture, better sensation recovery and less damage to the donor site. It is an ideal flap for reconstruction of thumbs and fingers.
RESUMEN
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.

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.
RESUMEN
@#Objective To investigate the differences and similarities of cognitive impairment，especially executive function，between patients with Parkinson’s disease（PD） and multi-system atrophy（MSA） by neuropsychological tests. Methods 26 patients with Parkinson’s disease，18 with multi-system atrophy and 20 with normal control were selected continuously. Age，education degree and course of disease were collected in detail. Montreal Cognitive Assessment （MoCA），Trail Making Test （TMT），Stroop Color-Word Test，Clock Drawing Test （CDT） and Rey-Osterriche complex figure test were given to evaluate cognitive and executive function of 26 patients with PD，18 patients with MSA and 20 normal controls randomly selected. Results Parkinson’s disease group and multi-system atrophy group had significantly lower scores in each test than the control group （P<0.05）. In the MOCA test，the scores of Parkinson’s patients were significantly lower than those of the multi-system atrophy group，［（22.34±3.18） vs（24.31±1.68），P<0.05]. The number of errors in the Stroop chromatogram test in Parkinson’s group was higher than that in the multi-system atrophy group［（10.74±6.31） vs（8.26±4.62），P<0.05]. In the remaining tests，there was no significant difference between PD and MSA patients （P>0.05）. Conclusion Parkinson’s disease patients and multi-system atrophy patients have different degrees of cognitive impairment and executive function decline than the normal population，Multisystem atrophy in terms of overall cognitive impairment is worse in patients with Parkinson’s disease than in patients with Parkinson’s disease，Parkinson’s disease patients have more attention deficit and more severe system atrophy，while patients with multiple system atrophy are more likely to have decreased self-examination ability and error correction ability.
RESUMEN
Objective To explore the clinical effect of complete transposition of arteriovenous in free flap artery crisis. Methods From October, 2009 to April, 2017, 13 cases of extremities tissue defect were repaired with free flaps.The intractable arterial crisis appeared after transplantation.Repeated anastomosis vessels were adapted but it was not relieved. Then the complete transposition of arteriovenous was adapted in the flaps. Namely the vein of the flap was anastomosed with the arterial in the recipient site to reconstruct the blood supply, and the arterial of the flap was anastomosed with the vein in the recipient site to reconstruct recirculation.Ten cases of hand defect and 3 cases of crus defect were repaired by 5 low abdominal flaps and 8 anterolateral thigh flaps. The tissue defect area was 16 cm× 7 cm-6 cm×4 cm and the flap area was 18 cm×8 cm-7 cm×4 cm. Results Ten flaps survived completely, the other 3 flaps almost survived that scab healed in 1 case and skin grafted in 2 cases. The flap for skin color was from purple red to dark red, and finally close to normal, and skin flap edge would have different degrees of ecchymosis; the bleed-ing from the incision of the skin flap was from dark red to bright red; the swelling of the flap was obvious in the early stage and the later swelling subsided. All cases were followed-up from 6 months to 32 months with an average of 16 months.The wounds healed well.The flaps had a clear boundary and soft texture. Conclusion Complete transposi-tion of the arteriovenous system can be used as an alternative in the presence of intractable arterial crisis after free flap transplantation, to save the flap and to reduce the trauma to the patient.
RESUMEN
OBJECTIVE: To summarize the clinical experience of the retrograde replantation for amputated toe. METHODS: Between January 2010 and August 2015, 11 cases of amputated toes (15 toes) were treated by the retrograde replantation. All patients were male, with a mean age of 31 years (range, 18-45 years). The causes included cutting injury in 6 cases (9 toes) and crush injury in 5 cases (6 toes). One case had amputated great toe and distal segment of the second toe combined with the third toe nail bed contusion; 1 case had amputated proximal great toe and middle segment of the second and third toes; 1 case had amputated proximal segment of great toe and middle segment of the second toe; 7 cases had amputated distal segment of the great toe; and 1 case had amputated middle segment of the fifth toe. The time from injury to hospital was 1-3 hours (mean, 2 hours). RESULTS: Thirteen toes survived completely after operation. Toe necrosis occurred in 1 toe; partial dorsal skins necrosis and nail bed necrosis occurred in 1 toe, and was cure after repaired with dorsalis pedis island flap. The rate of success for replantation of amputated toes was 93.33% (14/15). X-ray examination showed fracture healing of all survival toes at 8-12 weeks after operation (mean, 10 weeks); internal fixation was removed. Eleven cases were followed up 3-12 months (mean, 7.5 months). The survival toes had good appearance and toenail. The two point discrimination was 9-12 mm (mean, 10 mm) at last follow-up. The patients could walk and run normally. CONCLUSIONS: It is an ideal surgical method to use retrograde replantation to treat amputated toe, with the advantages of simple operation and high survival rate.
