ABSTRACT
The complete reconstruction of any soft tissue defect includes even the sensory recovery which is very significant aspect pertaining to prognosis. Superficial nerves in the vicinity of the vascular axis can be considered as vascular relays and neuroskin grafts can be constructed on them. Variations in innervation to various part of the dorsum of the foot by this nerve should be kept in mind while making these grafts. Authors dissected 50 formalinized cadaveric feet and studied normal anatomy and variations in origin, course, branching pattern, communications, and any other variations in medial, intermediate and lateral dorsal cutaneous nerve. The intermediate dorsal cutaneous nerve was innervating larger area of the skin around 3rd and 4th web spaces in 60% of cadaveric feet. The 2nd web space was innervated by medial dorsal cutaneous nerve in 92% of cadaveric feet. In 52% of cadaveric feet communicating branches were found between intermediate dorsal cutaneous nerve and lateral dorsal cutaneous nerve. In 63% cadaveric feet communicating branches were found between medial dorsal cutaneous nerve and branch of deep peroneal nerve to 2nd web space. The mean distance between lateral malleolus and intermediate dorsal cutaneous nerve was 4.05cm. These all observations can provide anatomical basis at the time of preparing medial dorsal cutaneous nerve flaps and intermediate dorsal cutaneous nerve flaps and also can minimize morbidity at donor site.
ABSTRACT
Objective:To investigate the surgical method and therapeutic effect on repairing soft tissue defects around ankle with lateral tarsal artery island flap.Methods:From July 2013 to December 2020, the lateral tarsal artery island flap were used to repair the soft tissue defects around ankle in 12 patients in Hand Surgery Department, Jiangnan Hospital Affiliated to Binjiang College. Of which, 6 patients had soft tissue defects complicated with bone or tendon exposure after injury and 6 had skin necrosis with internal fixation after fracture. The area of soft tissue defects was 6.0 cm×4.0 cm-9.0 cm×5.0 cm, and the size of the flaps was 7.0 cm×5.0 cm-10.0 cm×6.0 cm. After the flap was freed, the vascular pedicle was separated up to the origin of dorsalis pedis artery. As the pedicel was not long enough in 1 patient, the dorsal pedis artery was ligated and transected at the origin of the lateral tarsal artery. Full thickness skin graft was used to repair the donor sites. The patients were treated with anti-infection and anticoagulant therapies. The postoperative follow-ups were conducted by outpatient clinic visit, telephone or WeChat interviews or home visit to observe the recoveries in texture, appearance, sensation, donor site and function of ankle.Results:All the flaps and skin grafts survived. The wound healed well without occurrence of ulcer. The follow-up ranged 6-108 months (mean 17 months). Appearance of the flaps was good. It was not bloated and the sensation was restored to S 2-S 3. Conclusion:It is a good method to apply the lateral tarsal artery island flap in repair of the soft tissue defects around ankle. It features a hidden donor site, simple operation and the high level of safety. The texture and appearance of the flap are close to those of the recipient site.
ABSTRACT
Objective:To explore the curative effects of thoracodorsal artery chimeric perforator flap used to repair extremity soft tissue defects complicated with a deep dead cavity.Methods:From July 2014 to July 2019, 17 patients with extremity soft tissue defects complicated with a deep dead cavity were repaired by a thoracodorsal artery chimeric perforator flap at Department of Orthopaedics, Xiangya Hospital. They were 10 males and 7 females, aged from 2 to 39 years (mean, 20.2 years). There were 7 cases of traffic accident trauma, 5 ones of chronic osteomyelitis, 2 ones of crushing injury and 3 ones of radical resection of tumor. The defects were located at the lower extremity in 15 cases and at the upper extremity in 2. The wound sizes ranged from 5 cm × 3 cm to 24 cm × 9 cm. All the wounds were complicated somewhat with a dead cavity or exposure of deep tissues after debridement. The muscular component of thoracodorsal artery chimeric perforator flap was used to fill the dead cavity while the skin component to cover the superficial wounds. The flap donor sites were closed directly. The flap survival and donor site recovery were followed up regularly after operation. The curative effects were assessed according to the comprehensive evaluation criteria of hand surgery for flaps.Results:Necrosis of the distal flap occurred in only one case which responded to dressing change; the flaps survived uneventfully in the other 16 cases. The recipient and donor sites of flaps healed primarily in all patients. Venous crisis developed in one case which survived uneventfully after vascular crisis exploration. The 17 patients were followed up for 6 to 24 months (mean, 15.8 months). In all patients the flap presented with good color, texture and elasticity but without obvious swelling. At the last follow-up, the curative effects by the comprehensive evaluation criteria of hand surgery for flaps were excellent in 10 cases, good in 6 and fair in one. Only linear scar remained at the flap donor site and abduction of the shoulder was not affected.Conclusion:The thoracodorsal artery chimeric perforator flap is an ideal means for repair of extremity soft tissue defects complicated with a deep dead cavity because it can repair the deep dead cavity and body surface wounds at the same time only after anastomosis of a bundle of vascular pedicles.
ABSTRACT
Background: Soft tissue defects of tendo Achillis and heel regions are difficult to reconstruct because of less vascularity and limited mobility of the skin. Most of these defects result from trauma, infection and excision of malignancy. Well vascularized tissues with sensation are needed to cover these defects as these regions are more prone for repeated friction and weight bearing. Aim was to study the versatility and applications of various flaps in the reconstruction of soft tissue defects of tendo Achillis and heel regionsMethods: This retrospective study was conducted in the Department of Plastic and Reconstructive Surgery, Thanjavur Medical College, Tamil Nadu, India from 2015-2019. About 22 patients with soft tissue defects of tendo Achillis and heel regions were studied. The aetiology of the defect, size of the defect and the outcome of treatment with various flaps were evaluated.Results: Of the 22 patients 20 patients were males and 2 patients were females. The age group ranged from 12 years to 68 years. Most of the defects were due to road traffic accidents. The soft tissue defects were classified into small, medium and large sized defects based on the area of the defects. Reverse sural artery flap extended lateral calcaneal artery flap, posterior tibial artery perforator flap and lateral supra malleolar flap were the various flaps used to cover these defects.Conclusions: Fascio cutaneous flaps play a major role in the reconstruction of tendo Achillis exposed defects and heel defects. Long term follow-up with physiotherapy is essential to achieve excellent function of tendo Achillis.
ABSTRACT
Background: Coverage of soft tissue defects around distal third of the leg, particularly ankle and foot is a common situation faced by a plastic and reconstructive surgeon. Options available for such defects are limited due to scarcity of additional soft tissue that can be used without exposing tendons or bone. Associated conditions such as major vascular compromise, comorbidities and lack of facilities or expertise make free tissue transfer less preferred. Distally based sural artery flap has been a frequently used flap in such conditions, easy to perform and has reproducible results. We extended the reach of the flap and reproduced the results.Methods: We performed extended reverse sural artery pedicled flaps in 19 patients who presented to us between 2015 to 2017 with soft tissue defects around ankle and foot. Patients included 15 post RTA, 2 diabetic foot, 1 post resection defect and 1 post burn contracture release defect. Size of the defect ranged between 8x6cm to 14x10cm. Average follow up period was ranging from 8 months to 2.5 years.Results: All the flaps healed well without any obvious complications except one patient in whom marginal necrosis (2 cm margin of distal most flap) was observed and was secondarily treated with skin grafting.Conclusions: We observed that extended reverse sural pedicle flap is a rapid, reliable option for coverage of soft tissue defects around ankle and heel, sparing major vessel compromise and lengthy surgical procedure during free tissue transfer. This flap should be the first option for the patients with trauma and defects over weight bearing foot in whom peroneal axis vessels are preserved.
ABSTRACT
Objective@#To investigate the early diagnosis method of pulmonary embolism in patients with skin and soft tissue defects after trauma.@*Methods@#From January 2011 to July 2014, 5 patients with skin and soft tissue defects and pulmonary embolism after trauma were admitted to Department of Plastic Surgery and Burns of the Affiliated Drum Tower Hospital of Nanjing University Medical School, including 4 males and 1 female, aged 26-68 years. The medical records of the 5 patients were retrospectively analyzed. Hierarchical screening of patients with suspected pulmonary embolism was performed after admission for 4-45 days. Computed tomography pulmonary angiography (CTPA) was performed immediately in 2 patients who had hemodynamic disorder and were able to tolerate CTPA, and pulmonary embolism was confirmed. Clinical risk assessment was conducted for the other 3 patients who had no obvious hemodynamic disorder and only had clinical manifestations of pulmonary embolism such as chest tightness and dyspnea. Among the 3 patients, two of them were assessed as high risk possibility by clinical risk assessment and diagnosed with pulmonary embolism by CTPA immediately. The other one patient′s clinical risk assessment was moderate risk possibility, but D-dimer was positive, and the patient was diagnosed with pulmonary embolism by CTPA immediately. Wound exudation of all patients was collected within 1 week after admission for microbial culture, and wound debridement and skin grafting were performed according to the wound condition. The color Doppler ultrasonography of blood vessel on lower extremity was performed to determine deep venous thrombosis of lower extremity after appearance of symptoms of pulmonary embolism. The patient was immediately given urokinase or recombinant tissue plasminogen activator by intravenous infusion for thrombolysis after definite diagnosis of pulmonary embolism. The activated partial thromboplastin time (APTT) was monitored after treatment, and standardized anticoagulation began when APTT was equal to or lower than 70 seconds. The treatment results of patients, D-dimer measurement value, bed time before definite diagnosis of pulmonary embolism, number of patients underwent wound debridement during hospitalization, definite diagnosis time of pulmonary embolism after wound debridement, and number of patients with deep venous thrombosis of lower extremity and wound infection were recorded.@*Results@#Wounds with skin and soft tissue defects of all patients were completely healed, all skin grafts survived well, pulmonary embolism recovered well after timely treatment, and the trunk and branches of involved pulmonary artery recovered blood supply. The course of disease ranged from 1 month to 3 months. The measurement value of D-dimer was 2.4-31.7 mg/L, and the measurement values of D-dimer of 4 patients were equal to or higher than 5.0 mg/L. The bed time before definite diagnosis of pulmonary embolism was 4-46 days, with an average of 23.2 days. Four patients underwent wound debridement during hospitalization. The definite diagnosis time of pulmonary embolism after the wound debridement was 14-40 days, with an average of 20.5 days. Four patients were diagnosed with deep venous thrombosis of lower extremity. All patients had wound infection, and the bacteria causing wound infection included Pseudomonas aeruginosa of 2 cases, Staphylococcus aureus of 2 cases, and Enterococcus faecalis of 1 case.@*Conclusions@#In the diagnosis process of pulmonary embolism in patients with skin and soft tissue defects after trauma, D-dimer positive, long-term bed rest, experiencing operation during hospitalization, and with deep vein thrombosis and wound infection can be regarded as the key points for diagnosis. When a patient has clinical symptoms of pulmonary embolism and the above conditions, the clinician should promptly perform hierarchical screening, select the corresponding examination to confirm pulmonary embolism, and immediately perform thrombolysis for the patient with pulmonary embolism according to the patient′s tolerance, thereby improving patient survival rate.
ABSTRACT
Objective@#To investigate the clinical outcome of modified thoracic umbilical flap, spanning chest and abdomen, in repairing large soft-tissue defect of limbs.@*Methods@#From April 2012 to March 2017, 7 patients with large soft-tissue defects of limbs were admitted in the Department of Traumatic Osteopathic, Yidu Central Hospital of Weifang. The patients include 5 males and 2 females, aged from 29 to 51 years, with the mean age of 43 years. Four patients had upper limb soft-tissue defect and 3 patients were lower limb. All limbs large soft-tissue defects were treated by ultra-long thoracic umbilical flaps, spanning chest and abdomen. Epigastric artery and intercostal arteries or lateral thoracic artery were included in the flap to provide double blood supply with only one vascular anastomosis.@*Results@#All 7 flaps(30 cm×9 cm-45 cm×13 cm) survived. The followed-up period was 3 months to 1 years. There was no necrosis or infection in tendon and bone observed. The texture of flaps in 5 patients were similar to surrounding skin, or slightly thickened by 2-3 mm. One patient had slightly bloated flap due to obesity, but had no effect on limb function. All patients were satisfied with the outcome.@*Conclusions@#Modified thoracic umbilical flap is an reasonable design for the repairment of large soft-tissue defect of limbs, and easily to carry out.
ABSTRACT
Objective@#This study aims to analyze the outcome of free perforator flap for repairing soft tissue defects on the dorsum of foot.@*Methods@#Thirty-six patients with soft tissue defects on the dorsum of foot were treated at a single institution from March 2015 to September 2017. They were 20 males and 16 females, aged from 21 to 59 years old, with the mean age of 39.4 years. The causes of injury include crush injury (n=19), traffic injury (n=15), and electric injury (n=2). The injury site involves left foot (n=19) and right foot (n=17). The defect area of soft tissue was from 4.4 cm ×6.6 cm to 7.1 cm×16.2 cm in size. The vacuum sealing drainage dressing (VSD) was performed for all patients at the first stage of operation. The fracture and dislocated bone were fixed using Kirschner needle and plate screw. The ruptured tendon was repaired at the same time. The flap transplantation was performed at the second stage of operation. Twelve patients were treated with free anterolateral thigh perforator flap, 15 patients were treated with free sural artery perforator flap, and 9 were free peroneal perforator flap. The skin flap was from 4.9 cm× 7.2 cm to 7.9 cm × 17.8 cm in size.@*Results@#All 36 flaps survived. The wounds of both donor and recipient area primarily healed, without infection or skin necrosis. The venous crisis occurred in 1 patient of anterolateral thigh flap and 1 patient of free medial sural flap within 24 hours after surgery. Both flaps survived after stitches removed and blood cleaned. All patients were followed up for 6—22 months, with an mean follow-up period of 9.8 months. Except for the swollen anterolateral thigh perforator flap in 2 patients, the other patients were satisfied with the shape of flap and in wearing shoes. The sensation of flap was good, and the two-point discrimination was 11—16 mm. There was no obvious dysfunction occurred in the donor site.@*Conclusions@#The free anterolateral thigh perforator flap, free sural artery perforator flap and free peroneal perforator flap are suitable for repairing soft tissue defects on the dorsum of the foot. A reasonable surgical plan can help to obtain satisfactory clinical outcome.
ABSTRACT
Objective@#To evaluate one-stage repair of leg open fracture with soft tissue defect by fixation plus skin flap.@*Methods@#From January 2011 to January 2018, 34 patients with leg open fracture plus soft tissue defect were treated at Department of Orthopedics, The Second Affiliated Hospital to Harbin Medical University. They were 31 males and 3 females, aged from 13 to 54 years(average, 35 years). According to the Gustilo classification, the defects were type ⅢA in 31 cases and type ⅢB in 3 cases.

ABSTRACT
Objective To explore a novel strategy to repair traumatic soft tissue defects in the head and face by tissue expansion in the early stage.Methods Eighteen patients with traumatic soft tissue defects were treated with thorough debridement leaving the wound unclosed or simply closed with thin split-thickness scalp skin grafting,and adjacent expander implantation in the early stage and expanded flap transposition in the second stage.Results There were 11 male patients and 7 female patients ranging in age from 3.5 to 40 years [mean,(19.4±12.2) years],with average 15 months follow-up (range,3-67 months).The average expansion time was 74.3 days (range,53-96 days).The total of 18 patients with 22 expanders were treated with satisfactory results.All the flaps survived and the skin color,texture and contour well matched to those of the peripheral tissue.Only one complication of infection happened in the 18 cases (5.56％) and total 22 expanders (4.55％),which was similar to the rate reported in the literature.There were no any other complications related to the expander.Conclusions Debridement and tissue expansion in the early stage have been proved a more effective strategy to repair traumatic soft tissue defects in the head and face,which can not only achieve satisfactory color,unbulky and well matched texture similar to normal,but also can avoid unnecessary donor site injuries and does not increase the infection rate of tissue expansion.
ABSTRACT
Objective:To analyze and investigate the clinical efficacy on repairing soft tissue defects of the thumb distal with dorsal neurocutaneous vascular flap.Methods:Select 100 cases of patients with soft tissue defects of the thumb distal from January 2014 to December 2016,who were randomly divided into two groups,the control group and observation group.Take the abdominal skin flap to repair soft tissue defects of the thumb distal in the control group,with the thumb distal with dorsal neurocutaneous vascular flap in the observation group.The survival condition,the indicators of feelings,the appearance of skin flap,as well as the DASH score of the hand fimction have been recorded and analyzed through follow-up patients,to observe the effects on repairing soft tissue defects in the two groups.Results:All transplanted tisssues were all survived in the observation group and control group.Compared with control group,the sense of touch,temperature sense,monofilament,two-point discrimination,scar contracture of the observation group were better(P＜0.05),the incidence of bloat was lower (P＜0.05).The DASH scores were 29.56± 2.14,38.13± 3.12 in the observation group and control group,which was significantly lower in the observation group than that of the control group(P＜0.05).Conclusion:The clinical efficacy of the dorsal neurocutaneous vascular flap is better than that of abdominal skin flap on repairing soft tissue defects of the thumb distal.For no injury for major vascular nerves,little influence on donor area,being simple to operate,being better feelings of the finger pulp,appearance,dorsal neurocutaneous vascular flap on repairing soft tissue defects of the thumb distal is an ideal choice.
ABSTRACT
Objective To investigate the clinical effectiveness of the reversed flaps pedicled with lateral vas-cular chain of dorsal branch of digital artery and perforating branch of the dorsal metacarpal artery for relaying repair of soft tissue defects at middle-distal part of the 2nd ～ 5th finger and donor site. Methods From June, 2014 to May, 2016, a total of 18 cases (11 male and 7 female) with soft tissue defects at middle-distal part of 2nd～5th fin-ger were treated with the reversed flap pedicled with lateral vascular chain of dorsal branch of digital artery. The donor site was repaired with the reversed flap pedicled with the perforating branch of the dorsal metacarpal artery. The aver-age age at the time of reconstruction was 41 years. The right hand was involved in 12 cases and the left in 6 cases. The etiologies of injury were avulsion (n=5) , crush (n=6), and saw-cut injury (n=7). There were 15 cases with soft tissue defect at the distal phalanx and 3 cases with loss of distal and middle phalanx. All these cases were exposed with bone or tendon. The defect size ranged from 1.0 cm × 1.8 cm to 2.0 cm × 3.0 cm. And the dimension of the re-versed flaps pedicled with lateral vascular chain of dorsal branch of digital artery and perforating branch of the dorsal metacarpal artery ranged from 1.2 cm × 2.0 cm to 2.3 cm × 3.3 cm, and 1.4 cm × 2.3 cm to 2.6 cm × 3.6 cm, respec-tively. Postoperative follow-up was done termly. Results All flaps survived uneventfully with primary healing at donor site. The mean of followed-up time was 11 months (ranged from 6 to 15 months). The appearance and texture of the flaps were satisfactory and similar to the surrounding tissue. There was only some linear scar left at the dorsum of the palm. On the basis of the MHQ, 16 patients were strongly satisfied (score 5) with the appearance of the flap, and the remaining 2 patients was satisfied (score 4) with the appearance. The static 2-point discrimination of the flaps at the middle-distal part of 2nd～5th finger was 5-9 mm. Based on TAM assessment, the function of the injured finger was graded as excellent in 15 cases, good in 3 cases. Conclusion The relaying reversed flaps pedicled with lat-eral vascular chain of dorsal branch of digital artery and perforating branch of the dorsal metacarpal artery can be applied for repair of soft tissue defects at middle-distal part of 2nd～5th finger and donor site with easy procedure, reliable blood supply, satisfactory results, good appearance as well as less complications at donor sites.

ABSTRACT
Introducción: El objetivo de este trabajo es comparar los resultados obtenidos en las lesiones combinadas complejas postraumáticas del tercio medio y distal de la pierna, tratadas en forma temprana o tardía. Materiales y Métodos: Se evaluaron retrospectivamente 14 pacientes tratados entre 2004 y 2012. Se los dividió en dos grupos: con cobertura de partes blandas realizada en los primeros 10 días posteriores al trauma (grupo I, 6 casos) y con cobertura después de los 10 días (grupo II, 8 casos). En el grupo I, la cobertura se efectuó con seis colgajos musculares libres de dorsal ancho y, en el grupo II, con seis colgajos musculares libres y dos colgajos fasciocutáneos rotatorios surales de base distal. Resultados: El seguimiento promedio fue de 39.5 meses en el grupo I y de 50.6 meses en el grupo II; el promedio de días de internación fue de 20.8 y 42.4, respectivamente. En dos casos del grupo I y seis casos del grupo II, todos con pérdida ósea de la tibia distal, se efectuó la reconstrucción ósea en dos tiempos. En dos pacientes, uno de cada grupo, se necrosó el colgajo muscular libre y se practicó la amputación infrarrotuliana. Conclusiones: En lesiones agudas, es recomendable la cobertura con colgajos libres, pero en lesiones crónicas, nuestras indicaciones se han ido modificando, y los colgajos fasciocutáneos rotatorios son nuestra primera opción de cobertura en la actualidad. Nivel de evidencia: IV
Introduction: The objective of this study is to evaluate treatment of complex combined post-traumatic injuries of the distal and middle third of the leg, and compare the results obtained with early versus delayed treatment. Methods: Fourteen patients treated between 2004 and 2012 were retrospectively evaluated. They were divided into two groups: those with soft tissues coverage performed during the first 10 days following trauma (group I, 6 cases) and those with coverage performed after 10 days (group II, 8 cases). Coverage was performed using six latissimus dorsi free flaps in group I, and with six muscle free flaps and two rotational fasciocutaneous flaps in group II. Results: Follow-up averaged 39.5 months in group I and 50.6 months in group II. Hospital stay averaged 20.8 days for group I and 42.4 days for group II. Staged bony reconstruction was performed in two patients from group I and six patients from group II, all with distal tibia bone loss. In two patients, one in each group, the muscle free flap became necrotic, and an amputation was performed. Conclusions: In lesions treated early coverage using free flaps should be favored; but in chronic ones, our practice has changed towards using rotatory fasciocutaneous flaps when possible.

Objective To investigate the clinical effects of the sural nerve and saphenous nerve nutrient vascular island flaps in repairing pediatric ankle or foot soft tissue defect.Methods From June 2009 to January 2013,19 cases of heel soft tissue defect were collected in hospitalized children,in which 10 cases of ankle or foot soft tissue defects were repaired with reversed sural nerve nutrient vascular island flaps and 9 cases with ankle or foot soft tissue defects with reversed saphenous nerve nutrient vascular island flaps.The skin defect areas were from 3 cm× 5 cm～5 cm× 13 cm.Results All neurocutaneous vascular flaps survived after transplantation,the wound of donor area and recipient area healed,and texture and color of flap were good.The postoperative follow-up for 3-30 months (an average 14 months) showed no secondary infection,sensory recovery for S3-S4,texture and color were similar to normal skin,and the limb shape and function were satisfactory.Conclusions The sural nerve and saphenous nerve nutrient vascular island flaps are reliable of blood supply,which do not damage the main vessel,and could reconstruct feeling.Such flaps are ideal to repair foot or ankle soft tissue defects.
