ABSTRACT
Objective:To discuss outcomes of emergency repairing for Gustilo III B and III C fractures of forearm with complicated tissue defects and the related influence factors.Methods:From January 2014 to Feburary 2022, data of 98 cases of Gustilo III B and III C fractures with large compound defects of soft tissue, blood vessel, bone, tendon or muscle from elbow to wrist were collected. Primary debridement, bone fixation, wound coverage by free flap, bone transfer(or bone cement filling) or dynamic reconstruction of muscle were completed with emergency surgery in Department of Hand and Foot Microsurgery, Xi'an Fengcheng Hospital. Postoperative follow-ups were conducted through outpatient clinic visits, telephone and WeChat reviews. Video clips, questionnaires and the latest information of patients were also analysed. Rank sum test and Chi-square test were used to examine the relationship between independent variables such as general condition, disease condition and surgical procedures of chimeric tissue transfer group and simple flap transfer group, together with dependent variables such as limb salvage, number of surgery, wound healing, function scores, and complications. P<0.05 were further included in the regression equation to discover the relationship between multiple independent variables and dependent variables. Results:Follow-up lasted for 6-96 months, with an average of 71.1 months. In the chimeric group, the limb salvage rate was at 95.1%, with an infection rate of 8.50% and an average number of surgery was 2.13±0.89. In the simple flap transfer group, the limb salvage rate was at 87.5%, with an infection rate of 15.38% and an average number of surgery was 2.62±0.64. The good rate of Anderson score was 65.3% and the average score of Disability of the Arm, Shoulder and Hand(DASH) was 32.9(0-60) points for all the patients. There were significant differences in dependent variables of limb salvage and infection rate between the 2 groups ( P<0.05). Ischemia time and method of bone fixation led to significant differences in number of surgery ( P<0.05). Methods of bone fixation and the types of flap made significant differences in wound healing ( P<0.05). Underlying disease, bonedefect, Gustilo classification and method of bone fixation all contributed to the significant differences in function score ( P<0.05 or P<0.01) . Conclusion:Emergency surgery for repair of serious injury of forearm has a relatively high limb salvage rate and good functional effects. The limb salvage rate is not correlated with independent variables such as severity of injury, Mangledextremity Severity Score (MESS) and ischemia time, while transfer of a simple flap or a chimeric flap is significantly correlated with the limb salvage rate, infection and wound healing. The severity of injury, ischemia time and bone defect are correlated with functional assessment, number of surgery and bone healing.
ABSTRACT
Objective:To scientifically measure and morphologically evaluate the anatomical shape of the skin in the first web space based on cadavers, and to guide the design of flap in this area.Methods:Sixteen human cadavers fixed with 10% formaldehyde without injury or deformity on the hand were selected in the Department of Hand Surgery, the Third Hospital of Suqian. According to the characteristics of the first web area, marker points were selected for measurement and morphological observation. Morphological characteristics of the first web with thumb radial abduction(r) or palmar abduction(p) were measured and compared. The t-test was used for statistical analysis. P<0.05 was considered statistically significant. According to the results of measurement, standardised shapes and parameters of the skin were obtained for flap repair of defect of the first web. Results:When the thumb was in palmar abduction, the maximum distance [a(p)] of the first web of female(F) and male(M) was 5.78/8.42 cm(F/M), and the skin [S(p)] was 17.09/23.63 cm 2(F/M), both were significantly greater than the distance [a(r)] at 4.86/6.28 cm and the area of skin area [S(r)] at 14.39/20.15 cm 2 when thumb was in the radial abduction position( P<0.05). There was no significant difference in the length of [b(r)] and [b(p)] alone the long axis of flap between palmar and radial abductions(7.54/9.38 cm and 7.34/9.74 cm, respectively) of the thumb( P>0.05). It was found that the area of first web was not shaped as a symmetrical spindle, but an irregular quadrilateral inclined to the index finger. Conclusion:Design and measurement of a flap for the first web space should take the maximum palmar abduction of a thumb as a reference. The asymmetric quadrilateral flap design is more in line with the anatomical and characteristics in the region.
ABSTRACT
Objective:To investigate the clinical effects of Ilizarov external fixation combined pedicle flap transfer in the treatment of infected tibial nonunion plus soft tissue defects.Methods:A retrospective study was performed to analyze the data of 35 patients with infected tibial nonunion plus soft tissue defects who had been admitted to Department of Orthopedic Trauma, Tianjin Hospital Affiliated to Tianjin University from July 2005 to July 2020. There were 25 males and 10 females with an age of (37.5±6.0) years. Their original traumas were 27 open and 8 closed fractures, with a disease course ranging from 8 to 42 months. Three patients had undergone 1 operation, 7 patients 2 operations, and 25 patients 3 or more operations. All patients presented with different degrees of skin and soft tissue defects or bone exposure, wound sinus formation and bone scaring. The size of pedicle flaps transferred ranged from 6 cm×5 cm to 15 cm×10 cm. Surgical transfer of skin flap and external fixation were performed at one stage in 25 patients while staged surgery was performed in 10 patients. The first stage consisted of local debridement, vacuum sealing drainage, and delayed flap operation while the second stage consisted of delayed flap transfer and Ilizarov external fixation. The survival of skin flap, limb shortening, bony union and complications were observed after operation. The limb function was evaluated according to the criteria of The Association for the Study and Application of Methods of Ilizarov (ASAMI) for bone and functional results.Results:All patients were followed up for (23.8±7.4) months. Fracture union was achieved in all. The flaps survived postoperatively, the wounds were repaired by the first intention, infection did not recur, and bony union was achieved in 32 patients. Partial necrosis of the flap edge occurred in 3 cases, but responded to dressing change. In the 10 patients undergoing delayed flap operation, 100% of the flaps survived. In all patients, the limbs were shortened by (0.8±0.1) cm, and the tibial fractures got united after (7.2±1.2) months. By the ASAMI criteria for bone results, 29 cases were excellent and 6 cases good; by the ASAMI criteria for functional results, 25 cases were excellent, 8 cases good, and 2 cases fair.Conclusion:As Ilizarov external fixation combined pedicle flap transfer can repair bone and soft-tissue defects at the same time, this surgical scheme facilitates infection control and leads to reliable outcomes.
ABSTRACT
Objective:To evaluate the efficacy of a calf tissue flap combined with antibiotic-loaded calcium sulfate (artificial bone or mixed iliac bone graft) in the treatment of foot and ankle osteomyelitis.Methods:A retrospective study was conducted to analyze the 11 cases of foot and ankle osteomyelitis which had been treated at Department of Hand and Microsurgery, The Third Hospital of Baoji from October 2018 to October 2021. There were 8 males and 3 females, aged (42.3±23.7) years. The chronic hypotoxic osteomyelitis was repaired and reconstructed after thorough debridement at one stage with a calf tissue flap combined with antibiotic-loaded calcium sulfate artificial bone to fill the cavity and cover the wound. The acute infected trauma was repaired and reconstructed after thorough debridement at the second stage with a calf tissue flap combined with antibiotic-loaded calcium sulfate artificial bone to fill the cavity and cover the wound only after the acute infection was controlled by local dressing, drainage or negative pressure therapy and systemic anti-infection treatment at the primary stage. The flap size ranged from 3.5 cm × 2.0 cm to 12.0 cm × 6.0 cm. Four cases were treated by a peroneal artery perforator flap combined with antibiotic-loaded calcium sulfate artificial bone, 3 cases by a flap with peroneal artery perforator and peroneal nerve trophic vessel combined with antibiotic-loaded calcium sulfate artificial bone, 3 cases by a posterior tibial artery perforator flap combined with antibiotic-loaded calcium sulfate artificial bone, and one by a peroneus longus muscle flap combined with antibiotic-loaded calcium sulfate artificial bone. Postoperatively, the flap survival, bone union time, ankle function and complications were observed; the therapeutic efficacy was evaluated by comparing infection control indexes at the final follow-up [clinical manifestations like local redness, swelling, pain, ulceration, and exudation, and white blood cell count (WBC), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and calcitoninogen (PCT)].Results:All the flaps survived except for one which developed necrosis at the distal 1/3 of the flap but responded to dressing change. All the patients were followed up for (22.6±11.5) months. The 6-month follow-up revealed that all the flaps were fine in shape and texture. Re-examinations showed that WBC, CRP, ESR and PCT were normal or close to normal, the local skin was free of redness, swelling or ulceration, and protective sensation was restored to varying degrees. X-ray at (12.1±2.3) months showed that lesions disappeared, bony union was achieved, the ankle joint regained basic flexion and extension, and the affected limb also regained weight-bearing and walking functions in all the patients but one whose X-ray at 18 months showed poor bony union but no other symptoms or signs.Conclusion:In the treatment of foot and ankle osteomyelitis, a calf tissue flap combined with antibiotic-loaded calcium sulfate artificial bone can promote bone healing and restore the function of the foot and ankle because it not only fills the cavity and covers the wound but also effectively controls the infection.
ABSTRACT
Objective:To investigate the clinical effect of combining medial plantar flap with medial foot flap for repairing weight-bearing area defects of the foot.Methods:A retrospective case series study was used to analyze the clinical data of 12 patients with weight-bearing area defects of the foot, who were admitted to the Affiliated Hospital of Zunyi Medical University from March 2020 to March 2022. There were 9 males and 3 females, with the age of 27-62 years [(39.3±8.7)years]. There were 4 patients with palm defects and 8 with heel defects. The defect area ranged from 10 cm×8 cm to 13 cm×12 cm. The cutting area of skin flap ranged from 11 cm×8 cm to 14 cm×13 cm. A total of 5 patients were treated with free flaps (4 patients with palm and 1 with heel defects) and 7 with pedicled flaps (all with heel defects). The flap donor areas were repaired with skin grafting. The flap survival was observed after surgery. At the last follow-up, the appearance, texture, and two point discrimination of the flap were recorded; the foot function was evaluated by Maryland foot function score; the sensory function of the reconstructed skin flap was evaluated by testing the two-point discrimination using a bipedal gauge.Results:The patients were followed up for 6-24 months [(11.8±5.3)months], and all the flaps survived. At the last follow-up, the flaps were free of any swelling and ulceration, with good texture and no sliding. The Maryland foot function score was (92.8±7.2)points at the last follow-up, which was significantly higher than the preoperative (36.6±6.1)points ( P<0.01), being excellent in 9 patients and good in 3. The two-point discrimination of the reconstructed flap was (17.8±5.7)mm at the last follow-up, and there was no significant difference compared with the contralateral (16.3±5.1)mm ( P>0.05). The sensation of the flap returned to normal. There were residual scars in the flap donor area after skin grafting, but no significant impact on foot movement. Conclusion:The medial plantar flap combined with medial foot flap has a large cutting area and good texture, meets the functional requirements, and achieves good postoperative sense recovery, making it a good choice for the repair of weight-bearing area defects of the foot.

Abstract Introduction Endoscopic transnasal access to the skull base, both for treatment and reconstruction, can cause olfactory morbidity. Knowing the main consequences of this intervention is essential to have objective criteria for decision-making regarding the appropriate surgical technique. Objectives The aim of this study is to determine the impact on olfactory function of the endonasal endoscopic access to the skull base with the creation of the nasoseptal flap. Methods A prospective research was carried out in which 22 patients who underwent endoscopic transnasal surgery at the skull base, with the creation of a nasoseptal flap. The Connecticut Chemosensory Clinical Research Center test was applied before and at the 1st, 3rd and 6th postoperative months. Results The results showed that only in the first month of follow-up the mean patient classification was statistically worse than at the other evaluation moments (p < 0.05), but there was no mean difference in the Connecticut score classification between the other moments (p > 0.05); that is, patients showed worsening in the 1st month and returned to the preoperative mean after the 3rd month of follow-up. Conclusion The present study showed that the postoperative decrease in olfaction is transient, since the patient's sense of smell returns to pre-surgical values in the 3rd postoperative month.

ABSTRACT
Objective:To evaluate the therapeutic effect of exposed bone cement in treatment of infectious bone and soft tissue defect by comparison with routine bone cement therapy.Methods:A retrospective analysis was carried out in 27 patients who had been treated from January 2016 to January 2020. Of the 27 patients, 12 were treated by exposed bone cement filling for bone defect at the first stage, followed by flap and bone grafting at the second stage. Other 15 patients were treated by routine bone cement filling and flap repair at the first stage, followed by bone grafting at the second stage. Regular dressing change was carried out after surgery. All patients entered follow-up by out-patient review for wound condition and X-ray. Infection rate of bone and soft tissue, time of bone union, flap survive rate and complication were compared between the 2 groups.Results:The follow-up lased for 9-24(16.5±3.9 ) months. The bone defects were all healed. The treatment time of bone defects in the group of exposed bone cement was 25-34(28.5±2.8) weeks. The treatment time of bone defect in the routine cement group was 25-36(29.6±3.4 )weeks. There was no statistical difference between the 2 groups( P<0.05). Two cases in each group had failed in infection control after bone cement implantation. With further debridement, cleaning and other treatment, the infection was under control. All flaps in the 2 groups survived. In the group of exposed bone cement, there were 3 flaps splitting, 2 hemorrhage(effusion) and 1 partial flap necrosis, In the routine bone cement group, there were 4 wound dehiscence, 8 hemorrhage(effusion) and 3 partial flaps necrosis. There was no significant difference in flap complications between the 2 groups( P>0.05). The healing of bone defect was evaluated by Samantha X-ray score, the scores of the 2 groups were 5.41±0.67 and 5.40±0.63, respectively, with no statistical significance. The Paley's approach was used to grade the bone healing and the function of adjacent joints. Paley bone defect healing evaluation results weve all excellent. Joint function assessment were as follow: in the group of exposed bone cement, 6 cases were excellent and 3 were good; in routine bone cement group: 6 cases were in excellent and 5 in good. There was no significant statistical difference. Conclusion:Compared with a routine bone cement treatment, the exposed bone cement in the treatment of infectious bone defects saw a fewer flap splitting and fewer hemorrhage/effusion, without an increase in bone and soft tissue infection. This procedure could be considered for further trials in the treatment of a composite defects of infected bone and soft tissue.
ABSTRACT
Objective:Anatomical study of the cross-donor flap pedicled with the peroneal artery and the discussion of the effect of clinical application, so as to describe a new method for the repair of large-area soft tissue defects in the foot and ankle.Methods:From June 2016 to August 2019, 12 specimens of adult lower limbs were studied. The popliteal arteries were perfused with perchloroethylene-ethyl acetate-lead oxide and red perchloroethylene-ethyl acetate. The origin, number, outer diameter, course and distribution of perforating branches of the peroneal artery were anatomically observed. The source, distribution and anastomosis of the skin nutrient vessels in the posterolateral area of the calf were also studied. Relationship of the blood supply between the peroneal arteries and veins and the nutritional vessels of the sural nerve were observed. In 9 patients, the peroneal artery and vein were designed as the pedicle of cross-donor flap in the repair of large soft tissue defects of foot and ankle. The patients were entered follow-up through outpatient visits and telephone interviews.Results:Among the 12 adult specimens of lower limbs, there were 65 perforating branches from the peroneal artery, 4-7 branches on each side, with an average of (5.41±1.00) branches. The diameter of the penetrating deep fascia was(1.07±0.36) mm. The perforator branches were mostly distributed in 3 sections of 4.0-11.0 cm, 16.0-21.0 cm and 24.0-27.0 cm away from the lateral malleolus, accounting for 48%, 24% and 17% of the total number of perforators, respectively. The outer diameters of the perforator vessels were (0.92±0.26)(0.56-1.68) mm, (1.32±0.38)(0.60-2.14) mm, and (0.98±0.28)(0.62-1.36) mm. The length of the pedicle of the perforator vessels were (3.91±0.96)(2.15-5.78) cm, (5.34±0.50)(4.01-5.85) cm, and (3.31±1.15)(2.16-5.66) cm. The perforating branches in the 3 sections appeared constantly. The diameter of the vessels was≥0.5 mm with an average length of at(4.19±1.16)(2.15-5.85) cm. The vascular network of the flap in the posterolateral area of the calf was mainly composed of subdermal vascular network and deep fascial vascular network. The deep fascia vascular network in the posterolateral area of the calf had 3 obvious longitudinal chains, including the medial sural neurotrophic vascular chain, the small saphenous vein-sural nerve communicating branch vascular chain and the lateral sural neurotrophic vascular chain, which took the nutrient blood supply from the perforating branches of the peroneal artery also formed a longitudinal and transverse anastomosis between the perforating branches of the peroneal artery. In the clinical trials performed on 9 patients, all soft tissue defects of foot and ankle were repaired. The composite tissue flap survived without infection or necrosis. The follow-up was lasted for 12 months to 3 years. The postoperative function and the donor site appearance were good and the patients walked normally. According to the American Orthopaedic Foot and Ankle Association(AOFAS) foot scoring standard, the function of affected feet were evaluated. Five patients were excellent and 4 were good.Conclusion:The cross-donor flaps pedicled with peroneal arteries and veins has sufficient blood supply and a large area. It provides a method for the repair of large-area soft tissue defects in the foot and ankle.
ABSTRACT
Objective:To investigate the effect of flap combined with 3D printed microporous titanium(tantalum)prosthesis in the treatment of lower extremity soft tissue defect with large bone defect.Methods:From January 2019 to December 2020, 2 patients with large soft tissue defects on dorsal foot together with large metatarsal bone defect and 4 patients with soft tissue defects of calf with large tibial bone defect were treated. The areas of soft tissue defect were 5.0 cm×8.0 cm-15.0 cm×10.0 cm. The length of the bone defect were 3.8 cm to 7.0 cm, 5.75 cm in average. In the first stage, metatarsal bone defect or tibial bone defect was filled with vancomycin blended bone cement, meanwhile, soft tissue defect was repaired with anterolateral femoral flap(ALTF) with vascular anastomosis in 2 cases of feet, and local fascia flap was trans-positioned in 4 cases of lower extremity defects. The sizes of repairing flap were 6.0 cm×8.5 cm-16.0 cm×11.0 cm. Two to 7 months after the initial surgery, the customer designed microporous titanium prostheses were used(5 cases with microporous titanium and 1 with microporous tantalum) to repair the bone defects. The wound healing, the integration of metatarsal and tibial fractures with 3D printed microporous titanium(tantalum) prostheses, and the walking condition were observed after surgery. The follow-up lasted from 6 to 25 months, with an average of 12.7 months.Results:The wound healing in 5 patients was good. The patients stood on the foot in 2 months after surgery, started to walk with the assistance of crutch in 3 months after surgery, and took walk without assistance in 5-6 months after surgery. Good osseous integration were achieved. One diabetic patient had infection of foot wound 3 months after surgery. After removal of microporous titanium prosthesis and replacement of vancomycin blended interstitial substance of bone cement, the wound healed and the patient resumed walking.Conclusion:It is an effective method to encourage the patients to take early ambulation after the surgery for lower extremity soft tissue defect with large bone defect that was repaired by a flap and 3D printed microporous titanium(tantalum)prosthesis. Further observations are required to investigate the long-term efficacy, and the reduction of prosthesis infection rate requires further exploration.
ABSTRACT
OBJECTIVES@#To summarize our experience with the sural neurofasciocutaneous flap for reconstructing the soft tissue defects over the forefoot distal to the connecting line of midpoints in the metatarsal bones, and to compare the outcomes between the flap for resurfacing the defects distal and proximal to the connecting line.@*METHODS@#The clinical data of 425 sural neurofasciocutaneous flaps for repairing the soft tissue defects in the middle and lower leg, ankle, and foot between Apr. 2002 and Apr. 2020 were reviewed. Based on the connecting line of midpoints of the metatarsals, the sural neurofasciocutaneous flaps were divided into a forefoot group (flaps with furthest edges distal to the connecting line) and a peri-ankle group (flaps with the furthest edges proximal to the connecting line).@*RESULTS@#The partial necrosis rate in the forefoot group (14.5%, 10/69) was significantly higher than that in the peri-ankle group (7.0%, 25/356), with significant difference (P<0.05). Using the flap alone or in combination with a simple salvage treatment, the ratio of successful coverages of the defects was 98.6% (68/69) in the forefoot group, and 97.8% (348/356) in the peri-ankle group, respectively, with no statistical difference (P>0.05).@*CONCLUSIONS@#The sural neurofasciocutaneous flap is a better choice for covering the soft tissue defects over the forefoot distal to the connecting line of midpoints of the metatarsal bones. The survival reliability of the sural neurofasciocutaneous flap reconstructing the soft tissue defect proximal to the connecting line is superior to that of the flap reconstructing the defect distal to the connecting line.

En este trabajo discutimos la presentación del mixoma odontogénico en el maxilar superior, los enfoques de trata- miento; detallando la importancia de plantear alternativas de tratamiento que permitan la reconstrucción inmediata generando la menor morbilidad posible.
Odontogenic myxoma is a locally aggressive benign neoplasm with a low prevalence (frequency 2% to 5% of odontogenic tumors) in the jaws. This tumor often presents as an asymptomatic expansive lesion without sensory nerve changes. The aim of this study is to detail the case of a 42-year-old male patient who attends the Oral and Maxillofacial Surgery service of the Hipólito Unanue National Hospital due to a slow-growing tumor in the upper jaw, which increased in size over time and displacing dental organs, and extending to the hard palate and part of the soft palate, the pathological diagnosis was odontogenic myxoma and received radical treatment (hemimaxilectomy) due to the aggressive nature of the tumor. In this work we discuss the presentation of odontogenic myxoma in the maxilla, treatment approaches; detailing the importance of proposing treatment alternatives that allow immediate reconstruction generating the least possible morbidity.
ABSTRACT
Las lesiones digitales son extremadamente frecuentes y cuando estas involucran al pulgar pueden comprometer importantemente la función de la mano, tanto así que su amputación afecta hasta un 50% la función global de la mano y disminuye su fuerza hasta en un 20%. Para poder mantener el largo del pulgar en muchas ocasiones se requiere de cobertura mediante el uso de colgajos, los cuales no siempre son realizados por un cirujano de mano. La elección correcta del colgajo es esencial para evitar la restricción de movilidad y limitación funcional del dedo lesionado, existiendo múltiples alternativas descritas, que varían en su capacidad de cobertura y complejidad, haciendo difícil una adecuada elección. Nuestro objetivo es resumir y entregar una estrategia de análisis de lesiones del pulgar que permita comprender el tipo de lesión y objetivos del tratamiento quirúrgico, para así optimizar la cobertura según cada caso y los resultados a largo plazo.
Digital injuries are frequent in medical practice. When they involve the thumb, it is important to consider that an amputation affects up to 50% of the hands' function and decreases its strength by up to 20%. Management of thumb injuries often requires coverage with local flaps, which are not always performed by hand surgeons. Choosing the right flap is essential to avoid restrictions in mobility and functional limitations of the injured finger. Our objective is to summarize and provide a strategy for the analysis of thumb injuries that may help to understand the different types of lesions, and the surgical approaches recommend in order to optimize coverage and long term results.

Objective:To investigate the clinical effect of free superficial circumflex iliac artery flap combined with anterolateral thigh flap in repairing large skin defect of the hand.Methods:A retrospective case series study was conducted to analyze the clinical data of 9 patients with large skin defect of the hand admitted to Ningbo No.6 Hospital from January 2016 to December 2019，including 7 males and 2 females，aged 31-63 years［（45.3±5.6）years］. The area of skin defect reanged from 20 cm×15 cm to 25 cm×20 cm. One side of the superficial circumflex iliac artery flap and the contralateral anterolateral thigh flap were used for repair. Both recipient and donor sites were sutured at the first stage. The ilioinguinal region and thigh donor region were sutured directly. The area of superficial circumflex iliac artery flap was from 19 cm×6 cm to 23 cm ×10 cm and that of anterolateral thigh flap was 19 cm×9 cm to 23 cm×8 cm. The flap survival，healing of donor and recipient area and complications were observed. At 1，6 and 12 months after operation，the function of the flap was evaluated by the late functional evaluation criteria of the flap，hand function by the upper limb functional evaluation criteria of the Chinese Medical Association，and scar condition of the donor site by Vancouver Scar Scale（VVS）. At the last follow-up，the color，elasticity，appearance and scar of the donor site were observed.Results:All patients were followed up for 6-18 months［（12.5±2.3）months］. All flaps survived successfully. All patients achieved donor-site healing at the first stage，except that one patient experienced incision dehiscence in the thigh donor site after operation and healed after the second stage suture. The texture and appearance of the flaps were good. The flap in 5 patients was obviously bloated. Therefore，the secondary skin flap repair was selected，and the appearance was significantly improved after operation. Scores for function of the flap and the hand were improved over time（ P<0.05）. At 12 months after operation，the function of the flap was excellent in 3 patients，good in 4 and fair in 2，with the excellent and good rate of 78%；the result of hand function was excellent in 3 patients，good in 3 and fair in 3，with the excellent and good rate of 67%. The VVS score of the donor site decreased from（9.7±1.3）points at postoperative 1 month to（5.7±0.9）points at postoperative 6 months and（3.4±0.8）points at postoperative 12 months（ P<0.05）. At the latest follow-up，the color and elasticity of the flap was similar to that of the surrounding skin tissue，only with slight bloating；the scar of the donor site was small. Conclusions:The free superficial circumflex iliac artery flap combined with anterolateral thigh flap can cover large skin defect of the hand at one time，with good appearance and texture of the flap. The appearance and function of the wounded hand are good after operation，leaving only linear scar in the donor site.
ABSTRACT
Objective:To investigate the efficacy of free thin sensate superficial circumflex iliac artery perforator flap based on lateral cutaneous branch of the subcostal nerve for repair of soft tissue defect in the foot and ankle.Methods:A retrospective case series study was made on clinical data of 9 patients with soft tissue defect in the foot and ankle admitted to 80th Group Military Hospital from December 2017 to December 2019. There were 8 males and 1 females, with the age of 28-63 years [(47.3±12.3)years] and the body mass index (BMI) of 16.7-27.8 kg/m 2 [(23.9±3.9)kg/m 2]. The size of soft tissue defect ranged from 10 cm×6 cm to 20 cm×12 cm. All patients were treated with the free thin sensate superficial circumflex iliac artery perforator flap based on lateral cutaneous branch of the subcostal nerve. After debridement or tumor resection, a thin sensate flap was harvested by intra-adipose tissue dissection between the superficial and deep fat layers. The size of flap ranged from 13 cm×8 cm and 13 cm×10 cm. The thickness of the defatted flap ranged from 3-6 mm. The distance from the anterosuperior iliac spine to the point where the lateral cutaneous branch of the subcostal nerve crossed the iliac crest ranged from 7.5-10.0 cm. The flap survival, complications, and reoperation were observed after operation. The sensory recovery of the flap was evaluated using Tinel sign and nine-grid method including monofilament touch perception, vibration perception, pinprick perception, temperature perception, and static two-point discrimination test. The joint range of motion, and shoewear and walking problems were recorded. At the last follow-up, the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was used to assess the affected foot and ankle. The injury at the donor site was detected as well. Results:All patients were followed up for 6-35 months [(21.1±10.1)months]. All flaps survived without infection or tumor reoccurrence. One patient developed ulceration, then surplus skin on the reconstructed heel was resected. One patient underwent flap debulking and removal of internal fixation. One or more sensory modalities within the nine areas in each flap could be detected at postoperative 3-6 months. The monofilament touch, vibration, pinprick, and temperature perception were presented in almost all regions of each flap at postoperative 12 months. However, only one patient in one region was noted with the static two-point discrimination, in which the distance of the two points was set as 25 mm. The range of ankle motion was slightly limited in 2 patients who underwent osseoligamentous complex reconstruction. All patients were able to wear normal shoes and walk without pain. At the last follow-up, the AOFAS ankle-hindfoot score ranged from 78 to 97 points [(86.4±7.4)points], significantly improved from preoperative 10-70 points [(44.2±18.4)points] ( P<0.01). No patients complained of pain at the donor site, but the widening linear scar was noted. Conclusion:For medium-sized soft tissue defect of the foot and ankle, the free thin sensate superficial circumflex iliac artery perforator flap based on lateral cutaneous branch of the subcostal nerve can be defatted with the requirement and has advantages in defect site appearance, sensory restoration, wearing ordinary shoes, painless walking, good functional recovery, and minimal donor site morbidity.
ABSTRACT
Introducción: Las secuelas de quemadura juegan un papel fundamental en la recuperación del paciente quemado, ya que tiene una repercusión funcional y estética; para decidir el tratamiento de las contracturas cicatriciales, se necesita una evaluación cuidadosa y una clasificación de las contracturas por sitio, se debe explorar las articulaciones afectadas y notar los rangos de movilidad y las deformidades resaltando cualquier contractura cicatrizal y una vez que se establezca adecua-damente el tipo de secuela se tomara decisiones para orientar a un óptimo tratamiento. Los avances en el conocimiento de la anatomía vascular, en conjunto con el método de disección de colgajos "estilo libre", han permitido el desarrollo de los colgajos en hélice (propeller flap). Presentación de casos: Durante el período de un año (2018-2019) se presentaron seis casos de secuelas de quemaduras que comprometieron articulaciones mayores y que fueron tratadas con colgajo de pedículo perforante en hélice. La edad de los pacientes se ubicó entre 5 a 60 años con una mediana de 29 años con secuelas de quemaduras. Un caso con infección de sitio quirúrgico y seis sin complicaciones. El tiempo quirúrgico entre 120 a 170 min, la estancia hospitalaria tuvo una me-diana de 19 días (rango 6 a 55días). El diámetro del colgajo fue entre 24cm2 y 84cm2, con diferentes diseños lobulado (un caso), bilobulado (tres casos), tetralobulado (dos casos); permitiendo que el defecto secundario se cierre de forma directa en cinco de ellos y en un caso se colocara injerto de piel. Discusión: La literatura científica provee evidencia de las ventajas al utilizar colgajos en hélice por la capacidad de recons-trucción del tejido en un procedimiento de una sola etapa, logrando obtener resultados similares que ofrecen los colgajos libres microvascularizados.Conclusiones: El colgajo en hélice mejora las retracciones en las articulaciones mayores devolviendo el rango de movili-dad, preserva el músculo subyacente, proporciona una menor morbilidad del sitio donante.
Introduction: The sequelae of burns play a fundamental role in the recovery of the burned patient, since they have a func-tional and aesthetic impact; To decide on the treatment of scar contractures, a careful evaluation and classification of the contractures by site is needed, the affected joints should be explored and ranges of motion and deformities noted highli-ghting any scar contractures and once the type of sequel, decisions will be made to guide a better treatment. Advances in the knowledge of vascular anatomy, together with the "freestyle" flap dissection method, have allowed the development of propeller flaps. Case presentation: During a one-year period (2018-2019), there were six cases of burn sequelae that compromised major joints and that were treated with a pedicled propeller flaps. The age of the patients ranged from 5 to 60 years with a median of 29 years with burn sequelae. One case with surgical site infection and six without complications. The surgery time between 120 and 170 min, the hospital stay had a median of 19 days (range 6 to 55 days). The diameter of the flap was between 24cm2and 84cm2, with different designs: lobed (one case), bilobed (three cases), tetralobed (two cases); considering that the secon-dary defect is closed directly in five of them and in one case a skin graft is placed. Discussion: The scientific literature provides evidence of the advantages of using pedicled propeller flaps due to the ability to reconstruct the tissue in a single-stage procedure, achieving similar results as those offered by microvascularized free flaps.Conclusions: The pedicled propeller flaps improves retractions in major joints, restoring the range of motion, preserving the underlying muscle, and providing less donor site morbidity.

ABSTRACT Introduction: The volumetric preservation of bone and soft tissue after a tooth extraction has special relevance in the esthetic zone when it will be rehabilitated by a dental implant. Objective: Describe the prosthodontics treatment in a socket with advanced buccal bone resorption, with a flapless technique for guided bone regeneration and with a dental implant and implant-supported single fixed prosthesis. Case presentation: A case is presented of a male 62-year-old partially dentate patient. Radiographic examination showed the presence of advanced buccal bone resorption in relation to the maxillary left lateral incisor. It was a result of the root displacement secondary to root fracture. In a first surgical phase the lateral incisor was extracted using an atraumatic periotome technique. Particulate cortical bone allograft was compacted into the site to fill the space that was previously occupied by the root of the tooth. Temporary restoration was performed using the extracted natural tooth, which was adhesively bonded to the adjacent teeth. Four months after grafting the extraction site showed an adequate height and width of the bone. In a second surgical phase, an implant was placed. Six months after implant placement, osseointegration was clinically confirmed and a provisional crown was screwed on the implant performed. The final restoration with a zirconium dioxide abutment and a full ceramic crown was obtained and cemented. Conclusions: Regeneration of the buccal plate was possible through the use of particulate cortical bone allograft and a resorbable collagen membrane adapted to the bone defect and placed in a position to recreate the buccal plate. This allowed the installation of an implant 4 months later, the procedure allowing esthetic and functional results using a single fixed prosthesis(AU)
RESUMEN Introducción: La preservación volumétrica de los huesos y tejidos blandos después de una extracción dental tiene especial relevancia en la zona estética cuando será rehabilitada por un implante dental. Objetivo: Describir el tratamiento de prótesis en una cavidad con reabsorción ósea bucal avanzada, con una técnica sin colgajo para la regeneración ósea guiada y con un implante dental y una prótesis fija única con soporte de implante. Presentación del caso: Paciente masculino de 62 años, edente parcial. El examen radiográfico mostró la presencia de reabsorción ósea bucal avanzada en relación con el incisivo lateral superior izquierdo. Fue el resultado del desplazamiento de la raíz secundario a la fractura de esta. En una primera fase quirúrgica, el incisivo lateral se extrajo utilizando una técnica de periotoma atraumático. El aloinjerto de hueso cortical particulado se compactó en el sitio para llenar el espacio que anteriormente ocupaba la raíz del diente. La restauración temporal se realizó utilizando el diente natural extraído, que se unió adhesivamente a los dientes adyacentes. Cuatro meses después del injerto, el sitio de extracción mostró una altura y anchura adecuadas del hueso. En una segunda fase quirúrgica, se colocó un implante. Seis meses después de la colocación del implante, se confirmó clínicamente la osteointegración y se realizó una corona provisional atornillada al implante. La restauración final con un pilar de dióxido de circonio y una corona de cerámica completa se obtuvo y se cementó. Conclusiones: La regeneración de la placa bucal fue posible mediante el uso de aloinjerto de hueso cortical particulado y una membrana de colágeno reabsorbible adaptada al defecto óseo y colocada en una posición para recrear la placa bucal. Esto permitió la instalación de un implante 4 meses después. El procedimiento permitió la estética y los resultados funcionales utilizando una única prótesis fija(AU)

Objective@#In this study, a new surgical technique was developed to reconstruct the lateral nail fold in the duplicated thumbs with a common nail and postoperative outcomes were evaluated.@*Methods@#From December 2012 to October 2015, sixteen duplicated thumbs with a common nail were treated in our hospital using a flap from resected finger pulp which did not include the nail and phalanx. Unilateral inverting suture was performed between the flap and nail bed to reconstruct the lateral nail fold and nail groove. Postoperative outcomes were evaluated by Wang-Gao scoring system (total 12).@*Results@#The follow-up period ranged from 10 to 45 months. The reconstructed nails were smooth and had a natural lunula, and the nail width was about 80%-100% of their normal sides. There was a right angle between the nail epithelium and lateral nail fold in four cases, and an acute angle in two cases. The reconstructed nails were asymmetrical in these thumbs. One patient showed a hypertrophy in the lateral nail fold. The reconstructed nails were evaluated by Wang-Gao scoring system: 10 in 2 cases, 11 in 4 and 12 in 10. All the cases had excellent results.@*Conclusions@#The nail width usually is more than 80% of the normal sides in the radial polydactyly with a common nail. The surgical technique can reconstruct a natural lateral nail fold and nail groove, and avoid the nail deformity caused by the Bilhaut-Cloquet procedure.
ABSTRACT
Introdução: Câncer de mama é o segundo tipo mais comum de câncer entre mulheres no Brasil. Estimam-se 59.700 casos novos de câncer de mama para o biênio 2018-2019. Reconstrução mamária é um procedimento seguro e vários procedimentos cirúrgicos são descritos para sua realização: técnicas conservadoras, retalhos de vizinhança, materiais aloplásticos, retalhos miocutâneos pediculados e microcirúrgicos. O objetivo deste estudo foi analisar os casos de reconstrução mamária pósmastectomia por câncer de mama, realizados em um período de 16 anos. Métodos: Foi realizada revisão de prontuários de pacientes submetidas à reconstrução mamária pós-mastectomia por câncer de mama, no período de janeiro de 2002 a dezembro de 2017. Resultados: No período analisado, 586 pacientes foram submetidas à reconstrução mamária. Em 160 pacientes a reconstrução mamária foi realizada com retalho miocutâneo do músculo retoabdominal (TRAM), 107 com técnicas conservadoras, 156 com retalho miocutâneo do músculo grande dorsal (RGD), 113 com próteses e 50 secundárias. Previamente a outubro de 2007, a porcentagem de pacientes submetidas a cirurgias bilaterais, somando-se TRAM e RGD, era de 30%, e a partir desse período a porcentagem passou para 83,3%. Houve algum tipo de complicação ou intercorrência em 203 (34,64%) pacientes operadas, totalizando de 335 complicações. Grande maioria apresentou intercorrências tratadas ambulatorialmente sem necessidade de reabordagem cirúrgica. Conclusão: Houve aumento da incidência de cirurgias bilaterais, fato atribuído ao aumento das mastectomias profiláticas na mama contralateral e aumento do número de reconstruções utilizando RGD em comparação com o TRAM, bem como o aumento significativo das reconstruções com implante de silicone.
Introduction: Breast cancer is the second most common type of cancer among women in Brazil. An estimated 59,700 new cases of breast cancer were reported in the 20182019 biennium. Breast reconstruction is a safe procedure, and various surgical procedures have been described, including conservative techniques and use of neighborhood flaps, alloplastic materials, and pedicled and microsurgical myocutaneous flaps. The objective of this study was to analyze cases of breast reconstruction after mastectomy for breast cancer performed over a period of 16 years. Methods: We reviewed the medical records of patients who underwent breast reconstruction after mastectomy for breast cancer between January 2002 and December 2017. Results: Within the study period, 586 patients underwent breast reconstruction. Breast reconstruction was performed with a transverse rectus abdominis myocutaneous muscle (TRAM) flap in 160 patients, with conservative techniques in 107 patients, with a latissimus dorsi myocutaneous flap (LDMF) in 156 patients, with prostheses in 113 patients, and secondarily in 50 patients. Before October 2007, the proportion of patients who underwent bilateral surgeries with a TRAM flap and LDMF was 30%, and since then, the percentage has increased to 83.3%. One or more types of complications occurred in 203 patients (34.64%) who underwent surgery, with a total of 335 complications . Most outpatient complications did not require surgical reassessment. Conclusion: The incidence of bilateral surgery increased, which is attributed to the increase in the number of prophylactic mastectomies in the contralateral breast and in the number of reconstructions using a LDMF compared with that using a TRAM flap. A significant increase in the number of reconstructions with silicone implants was also observed.
