Introducción. Las armas de energía cinética son diseñadas para generar lesiones dolorosas y superficiales. Sin embargo, las lesiones asociadas causan confusión al ser abordadas como heridas por proyectil de arma de fuego, convirtiendo el enfoque y el manejo correcto en un desafío. El caso presentado describe un paciente herido en el cuello por arma traumática con el objetivo de analizar factores que permitan identificar este tipo de heridas y sus implicaciones en el manejo. Caso clínico. Paciente masculino de 31 años que ingresó con intubación orotraqueal, remitido de una institución de nivel 2, con herida por aparente proyectil de arma de fuego con trayectoria transcervical. Se encontró hemodinámicamente estable, pero con dificultad para la valoración clínica, por lo que se realizaron exámenes complementarios que descartaron lesión aerodigestiva. La tomografía de cuello reportó proyectil alojado en musculatura paravertebral izquierda, descartando trayectoria transcervical. Discusión. El comportamiento de las lesiones asociadas a los proyectiles de armas depende de varios factores, como el tipo de material del proyectil, su velocidad y las propiedades del tejido impactado. Se presentó un caso en que inicialmente se sospechaba una lesión transcervical, pero con la evaluación se identificó el proyectil cinético en la musculatura paravertebral. Conclusión. En el abordaje de un paciente con sospecha de herida por proyectil de arma de fuego se debe considerar ante todo la respuesta clínica y la correlación del supuesto vector del proyectil con las lesiones sospechadas. La evaluación imagenológica permite identificar oportunamente los proyectiles y evitar procedimientos o terapias innecesarias que forman parte del manejo convencional del paciente con trauma penetrante

Introduction. Kinetic energy weapons are designed to produce superficial and painful injuries. Nevertheless, the approach of these patients in the emergency department can be confusing as they can be managed as gunshot wounds. This case describes a patient with an injury in the neck caused by kinetic energy gun. In addition, we analyzed factors that might identify these wounds and their implications in the management. Clinical case. A 31-year-old male patient who presented to the emergency department referred from a second level hospital with gunshot wound with suspected trans-cervical trajectory. They performed orotracheal intubation and transferred to our institution. Due to the patient ́s hemodynamic stability and impossibility for clinical evaluation, test and radiology tests were performed. These ruled out any aero-digestive injuries. The CT-scan reported a bullet hosted in the left paravertebral muscles, ruling out a trans-cervical trajectory. Discussion. Several factors contribute to the injuries produced by kinetic energy weapons. The injury patterns may vary according to the bullet material, muzzle velocity and impacted tissue characteristics. In this case, an initial trans-cervical injury was suspected and due to clinical evaluation we identified the bullet hosted in the paravertebral muscles. Conclusion. In the approach of a patient with suspicion of gunshot wound, as surgical team we must consider clinical manifestations and the correlation of the vector with suspected injuries. Evaluation of diagnostic imaging allows the identification of traumatic bullets, avoiding unnecessary procedures in the conventional management of patients with penetrating trauma

The sources of common knee valgus deformities were classified in order to better plan the orthopedic methods, matching prostheses and soft tissue repair of knee valgus deformities.Based on the analysis of typical clinical cases and the operability of classification standards in practical clinical practice, it is of great significance to establish a reasonable morphological classification of knee valgus deformity, in order to grasp the characteristics and patterns of the onset of valgus deformity. According to the origin of the deformity and the tension of the medial and lateral collateral ligaments, the classification of the genu valgus deformity can be divided into the classification of the traditional Genu valgum deformity origin and the classification of the new Genu valgum deformity origin. Although both of them highlight the skeletal characteristics and soft tissue conditions of the valgus deformity, they are quite different. Traditional classification is based on femoral tibial angle, valgus angle, etc; The new classification is divided into mechanical angle, anatomical angle, distal condylar angle, etc. The origin of Genu valgum deformity is generally complex. The traditional classification cannot fully reflect the origin of valgus deformity and the tension state of soft tissue. The new classification, especially based on the classification of anatomical angle valgus deformity, can not only reflect the morphological and anatomical details of knee valgus deformity, but also reflect the tension state of the medial and lateral collateral ligaments and local soft tissue stress state that determine the stability of the knee joint. At present, the commonly used surgical methods for valgus deformity of the knee include periarticular osteotomy of the knee and total knee Joint replacement. The former focuses on correcting extraarticular deformity without over repairing ligaments, and the latter focuses on force line correction, which is the final treatment for terminal valgus deformity. The application of digital technology in clinical orthopedics can improve the accuracy of implant placement. Implant placement needs to be based on the patient's bone characteristics and degree of deformity. For patients with severe deformity, the application of digital technology can improve the accuracy of implant placement and assist in the treatment of knee valgus deformity.

Objective:To analyze the necessity of anastomosis of the cutaneous nerve by comparing anterolateral femoral flaps with versus without anastomosis of the anterolateral femoral cutaneous nerve in the repair of extremity soft tissue defects.Methods:A retrospective analysis was made of the clinical data of 30 patients with extremity soft tissue defects who had been admitted to Department of Orthopedics, The Sixth People's Hospital affiliated to Shanghai Jiaotong University School of Medicine from September 2019 to March 2022. The patients were assigned into 2 groups according to whether the anterolateral femoral cutaneous nerve was anastomosed or not in the repair of extremity soft tissue defects using anterolateral femoral flaps. In the anastomosis groups of 14 cases, there were 7 males and 7 females, with an age of (46.4±15.2) years and a flap size of (22.4±7.3) cm×(8.5±1.3) cm. In the non-anastomosis group of 16 cases, there were 11 males and 5 females, with an age of (39.9±15.8) years and a flap size of (23.0±6.4) cm×(9.0±2.1) cm. The 2 groups were compared in terms of flap survival, Semmes-Weinstein recovery degree and area of monofilament tactile sensation, and time periods for temperature sensation and two-point discrimination.Results:There was no statistically significant difference between the 2 groups in the preoperative general data, showing they were comparable ( P>0.05). All the flaps survived completely without vascular crisis. In the anastomosis group, the time periods required for Semmes-Weinstein recovery of monofilament tactile sensation to the areas of 20.0%, 50.0%, and 80.0% [(2.5±0.7) months, (6.7±1.1) months, and (11.0±1.2) months] were significantly shorter than those in the non-anastomosis group [(3.6±1.3) months, (8.6±1.4) months, and (15.0±2.2) months], the recovery area at the last follow-up [100.0% (100.0%, 100.0%)] was significantly larger than that in the non-anastomosis group [84.6% (81.7%, 89.9%)], and the time period for recovery of temperature sensation [(3.9±0.7) months] significantly shorter than that in the non-anastomosis group [(6.1±1.1) months] (all P<0.05). The time for recovery of two-point discrimination in the 14 patients in the anastomosis group was (10.4±1.7) months while only 7 of the 16 patients in the non-anastomosis group recovered two-point discrimination after (14.7±1.4) months, showing a significant difference between the 2 groups ( P<0.05). Conclusion:In the repair of extremity soft tissue defects using anterolateral femoral flaps, compared with no anastomosis of the cutaneous nerve, anastomosis of the anterolateral femoral cutaneous nerve may ensure more or less the sensory recovery of the flaps.

Objective:To introduce the concept and procedures of precise flap surgery in construction of knee defects and to report the preliminary clinical outcomes.Methods:The data of 16 patients with knee defects at 17 sides were retrospectively analyzed who had been treated under the guidance of the concept of precise flap surgery at Department of Orthopedic Surgery, The 920th Hospital of Joint Logistic Support Force of PLA from August 2014 to March 2022. There were 12 males and 4 females, aged 44(34, 54) years. The wounds were at the left side in 8 cases, at the right side in 7 ones and at bilateral sides in one, and their sizes ranged from 5 cm×3 cm to 15 cm×11 cm. The time from injury to surgery was 8.5(6.0, 13.0) days. Optimal repair protocols were chosen after the donor and recipient sites were evaluated according to the methods of precise flap surgery: a retrograde anterolateral thigh flap in 7 sides, a descending genicular artery perforator flap in 3 ones, a saphenous artery flap in 2 ones, and a superior genicular lateral artery perforator flap, a popliteal artery perforator flap, a medial sural perforator propeller flap, a peroneal artery perforator propeller flap, and a randomized flap in one, respectively. The flap sizes ranged from 10 cm×6 cm to 15 cm×15 cm. The outcomes and complications of skin flap repair, and functional recovery of the affected limb were recorded.Results:All the flaps at 17 sides survived after surgery; 3 cases developed distal edge necrosis which responded to dressing change. The follow-ups for the 16 patients were 14.5(10.0, 28.0) months. All the flaps presented with good color, texture and contour. Flap bulking, local osteomyelitis, and scar ulcer was found in one case respectively. According to the revascularization assessments in the digital replantation criteria by Hand Surgery Society, Chinese Medical Association, all the flaps at 17 sides were excellent. Accoding to the knee functional evaluation of Hospital for Special Surgery (HSS) at the last follow-up, the 17 affected limbs scored 86(80,91) points, yielding 9 excellent, 7 good and 1 fair sides.Conclusion:Although the defects and donor sites around the knee vary greatly, precise flap surgery may lead to effective control of the variations, choice of an optimal reconstruction protocol, and precise wound repair.

Objective:To investigate the application of artificial intelligence based on the neural network radiation field in repair of soft tissue defects at lower limbs.Methods:A retrospective analysis was performed of the 23 patients who had been admitted to Department of Orthopedic Surgery, Renmin Hospital of Wuhan University from June 2020 to May 2022 for soft tissue defects at lower limbs. There were 14 males and 9 females, aged (38.6±6.7) years. Causes for soft tissue defects: traffic injury in 9 cases, benign or malignant primary soft tissue tumor in 6 cases, mechanical injury in 4 cases, crush injury in 2 cases, and chronic ulcer in 2 cases. Defect locations: the thigh in 3 cases, the lower leg in 7 cases, and the ankle and distal foot in 13 cases. The areas of soft tissue defect ranged from 6.0 cm×3.8 cm to 14.7 cm×12.8 cm. The defects were repaired and reconstructed by transplantation of an anterolateral femoral free flap in 7 cases and a pedicled flap in 16 cases with the assistance of artificial intelligence based on the neural network radiation field, a cutting-edge artificial intelligence algorithm that can quickly construct and process three-dimensional model images through volume rendering under the radiation field. The flap survival rate, aesthetic satisfaction before and after treatment, time for skin flap harvesting and transplantation, functional recovery of lower limbs and incidence of complications were recorded.Results:All the 23 patients were followed up for 32(28, 36) weeks. All the flaps were harvested smoothly and survived. The time for flap harvesting and transplantation was 65.8(50.0, 76.0) min. The aesthetic satisfaction scored (2.3±0.7) points before treatment and (8.4±1.6) points 4 weeks after treatment, showing a statistically significant difference ( P<0.05). The skin flaps healed well with no complications such as hematoma or infection in all but one patient who suffered from superficial necrosis at the distal skin flap due to venous crisis but healed with a scar. On average, the functional recovery of lower limbs scored 23.7(22.0, 25.0) points at 12 weeks after operation according to the Enneking evaluation system, and the functional recovery of lower limbs was 79% (23.7/30.0). Conclusion:Application of artificial intelligence based on the neural network radiation field can achieve ideal results in repair of soft tissue defects at lower limbs, due to its advantages of rapid and accurate surgical procedures, limited damage to the donor site, and a short learning curve.

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.

Objective:To compare the efficacy of modified single-incision and traditional double-incision for flexor hallucis longus tendon transfer in the treatment of Myerson type III chronic Achilles tendon ruptures in the middle-aged and elderly patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 106 patients with Myerson type III chronic Achilles tendon ruptures admitted to Ningbo No.6 Hospital from January 2015 to May 2021, including 54 males and 52 females; aged 48-82 years [(67.2±8.4)years]. Flexor hallucis longus tendon transfer was assigned to 60 patients using modified single-incision (modified single-incision group) and to 46 patients using traditional double-incision (traditional double-incision group). The operation time, intraoperative blood loss as well as American foot and ankle society (AOFAS) ankle-hindfoot score, foot and ankle outcome score (FAOS), visual analogue score (VAS) before operation, at postoperative 12 months and at the last follow-up were compared between the two groups. Time to recover walking and self-care ability, and incidence of complications were compared as well.Results:All patients were followed up for 16-52 months [(37.4±9.5)months]. The operation time and intraoperative blood loss were (51.6±7.4)minutes and (16.6±3.9)ml in modified single-incision group compared to (72.8±7.5)minutes and (32.9±5.2)ml in traditional double-incision group (all P<0.01). There was no significant difference in the AOFAS ankle-hindfoot score, FAOS and VAS between the two groups before operation (all P>0.05). At postoperative 12 months and at the last follow-up, AOFAS ankle-hindfoot score and VAS were not significantly different between the two groups (all P>0.05), but FAOS in modified single-incision group [(112.6±3.0)points, (114.4±3.1)points] was improved significantly compared with traditional double-incision group [(110.8±4.1)points, (112.7±4.3)points] ( P<0.05 or 0.01). At postoperative 12 months and at the last follow-up, the AOFAS ankle-hindfoot score, FAOS and VAS in both groups were improved or decreased significantly compared with those before operation (all P<0.05). All patients recovered their pre-injury daily activities. The time to recover walking and self-care ability were (9.6±2.0)weeks and (12.7±1.7)weeks in modified single-incision group compared to (10.8±1.8)weeks and (13.7±1.9)weeks in traditional double-incision group (all P<0.01). In modified single-incision group, superficial incision infection ( n=1) was found and cured after oral antibiotics. In traditional double-incision group, superficial incision infection ( n=2), deep incision infection ( n=1), deep venous thrombosis ( n=1) and medial plantar nerve injury ( n=1) were found and cured after symptomatic internal medical therapy; claw toe deformity ( n=2) was found and relieved after wearing customized insoles and functional exercise. The incidence of complications was 1.7% (1/60) in modified single-incision group compared to 15.2% (7/46) in traditional double-incision group ( P<0.01). Conclusion:In contrast with traditional double-incision surgery, modified single-incision for flexor longus tendon transfer in the treatment of Myerson type III chronic Achilles tendon ruptures in the middle-aged and elderly patients has advantages such as shorter operation time, less intraoperative blood loss, better functional recovery, faster postoperative recovery and less complications.

Objective:To explore the outcome of sponge forceps assisted threading with Speedbridge technique for the treatment of acute closed Achilles tendon rupture.Methods:A retrospective case series study was conducted on 20 patients with acute closed Achilles tendon rupture treated in Zhengzhou Orthopedic Hospital from December 2019 to December 2021. There were 18 males and 2 females, with age range of 24-43 years [(29.5±7.6)years]. All patients were with unilateral injury, involving the left side in 13 patients and right side in 7. Examinations revealed a palpable defect in the Achilles tendon and positive Thompson test. A longitudinal incision was made at the medial edge of the ruptured tendon. Three nonabsorbable sutures were passed through the proximal stump with sponge forceps, bypassed the rupture site and fixed directly into the calcaneal bone. The disrupted tendon ends were aligned by the tendon-bundle technique using 4-0 absorbable sutures. The operation time and incision length were documented. The ankle joint range of motion (dorsiflexion/plantar flexion), American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and Achilles tendon total rupture score (ATRS) in the affected and healthy side were compared at 3, 6 and 12 months postoperatively. The wound healing and complications were observed.Results:All patients were followed up for 12-16 months [(13.2±2.5)months]. The operation time was 40-66 minutes [(52.0±10.3)minutes], with the incision length of 3-4 cm [(3.3±0.7)cm]. In the affected side at 3 and 6 months postoperatively, the ankle joint dorsiflexion [(5.6±1.5)°, (10.5±0.2)°] and plantar flexion [(28.4±3.2)°, (33.5±1.5)°] showed statistically significant difference compared with the healthy side (all P<0.05). The ankle joint dorsiflexion [(13.9±0.7)°] and plantar flexion [(38.3±4.4)°] in the affected side were not statistically different from that of the healthy side at 12 months postoperatively (all P>0.05). The AOFAS ankle-hindfoot score was (58.3±5.4)points, (84.9±7.1)points and (91.8±6.3)points at 3, 6 and 12 months postoperatively, showing a gradual rise (all P<0.05). The ATRS was (60.5±4.9)points, (85.5±9.0)points and (93.1±5.7)points at 3, 6 and 12 months postoperatively, showing a gradual rise (all P<0.05). All incisions were healed primarily. No patients had wound infection, nerve injury or re-rupture. Pain at the anchor insertion site occurred in 2 patients at 1 month after operation and relieved after active functional rehabilitation at 4 months after operation. Transient pain at the Achilles tendon insertion occurred in 1 patient at 6 months after operation, and relieved after 2 weeks of oral non-steroidal anti-inflammatory drugs treatment. Conclusion:For acute closed Achilles tendon rupture, sponge forceps assisted threading with Speedbridge technique can attain short operation time, small incision and good functional recovery, with few complications.

ABSTRACT Introduction: Quercetin (Q) is a flavonoid that has been shown to be an antioxidant in vitro. A current review is necessary to evaluate whether Q can improve biochemical damage markers following exercise-induced muscle damage (EIMD) and delayed onset muscle soreness (DOMS). Objective: Specify the impact of Q supplementation on EIMD, DOMS, and inflammatory cytokines (IL-6, IL-10, and TNF-α) after exercise. Methods: Participants (n=28) were randomly assigned to Q (1000 mg/day) and placebo (PLA). Intake was done 48 hours before EMID to 96 hours after EMID (one week). Before EIMD (PRE) and 24, 48, 72, and 96 hours after EIMD, blood samples were collected for CK and measurement of inflammatory cytokines. ANOVA test was used for data analysis with a significance P > 0.05. Results: Peak DOMS was seen 48 hours after EIMD, regardless of the DOMS combination. Q had a significant reducing effect on CK response at 24 hours (-43%), 48 hours (-48%), 72 hours (-56%), and 96 hours (-67%) after EIMD compared to placebo. IL-10 and IL-6 did not change statistically for the applied sample size. TNF-α was lower by Q intake significantly at 24 hours (-24%), 48 hours (-22%), and 96 hours (-22%) compared to PLA. Furthermore, the TNF-α trend was lower with Q intake at 72 hours (-19%). Conclusion: Q supplementation decreased biological inflammation during post-IMD recovery but not quadriceps DOMS. Level of Evidence: Therapeutic Studies - Investigating Treatment Outcomes.

RESUMO Introdução: A quercetina (Q) é um flavonóide que provou ser um antioxidante in vitro. Fez-se necessária uma revisão atual projetada para avaliar se a Q pode melhorar os marcadores bioquímicos de dano após o dano muscular induzido pelo exercício (EIMD) e a dor muscular de início retardado (DOMS). Objetivo: O objetivo da revisão atual foi especificar o impacto da suplementação Q sobre EIMD, DOMS e citocinas inflamatórias (IL-6, IL-10 e TNF-α) após o exercício. Métodos: Os participantes (n=28) foram alocados em Q (1000 mg/dia) e placebo (PLA) aleatoriamente. Fez-se ingestão 48 horas antes da EMID a 96 horas após a EMID (uma semana). Antes da EIMD (PRE) e 24, 48, 72 e 96 horas após a EIMD, amostras de sangue coletadas para CK e medição de citocinas inflamatórias. O teste ANOVA foi usado para análise de dados com significância P > 0,05. Resultados: O pico DOMS foi visto em 48 horas após EIMD, independentemente da combinação de DOMS. Q teve um efeito de redução significativo na resposta CK em 24 horas (-43%), 48 horas (-48%), 72 horas (-56%) e 96 horas (-67%) após a EIMD em comparação com placebo. IL-10 e IL-6 não mudaram estatisticamente para o tamanho da amostra aplicada. TNF-α foi menor pela ingestão de Q significativamente às 24 horas (-24%), 48 horas (-22%), e 96 horas (-22%) em comparação com o PLA. Ademais, a tendência TNF-α foi menor com a ingestão de Q às 72 horas (-19%). Conclusão: A suplementação de Q diminuiu a inflamação biológica durante a recuperação pós EIMD, porém não os DOMS do quadríceps. Nível de evidência: Estudos Terapêuticos - Investigando os Resultados de tratamento.

ABSTRACT Introduction: Cherry extract has a high amount of anthocyanins and flavonoids containing antioxidant effects. Its high antioxidant characteristics have been shown to reduce markers of delayed muscle soreness (DOMS) and exercise-induced muscle damage (EIMD) to improve recovery after exercise. Objective: Verify the effects of the cherry extract on post-exercise muscle damage. Methods: Google scholar, Medline, and Scopus were systematically searched until February 2022. The Cochrane Collaboration tool was applied to determine the risks of bias. Results: The results showed that cherry extract administration did not have a decreasing impact on creatine kinase levels overall: (WMD = 12.85 IU. L-1, 95% CI: −35.94, 61.64; P = 0.606). Considerable heterogeneity was observed among the articles (Cochran's Q-test = 990.80, P = 0.000, I2 = 96.7 %). However, there is a significant reducing effect on pain sensation by the consumption of cherry extract (WMD = −6.105 mm; 95% CI: −11.193 −1.017; p = 0.019). Conclusion: Cherry extract consumption effectively reduced late-onset muscle pain among participants in the overall and subgroup analysis. Thus, the cherry extract may be a complementary alternative in recovery after exercise. Level of evidence II; Therapeutic studies - Manuscript review.

O tratamento das feridas complexas com grande perda de partes moles é um desafio para a cirurgia plástica, principalmente quando a ferida encontra-se infectada. Várias opções são consideradas para o tratamento, como sutura, enxertos, retalhos, expansores. Devido à complexidade dos casos, frequente associação de morbidades, necessidade de intervenções multidisciplinar e longos internamentos, os custos do tratamento são frequentemente elevados. Este trabalho vem demonstrar a técnica de sutura elástica empregada em um caso clínico, utilizando tração contínua da pele em associação ao curativo a vácuo, que possibilitou reabilitação do paciente sem a necessidade de intervenções mais agressivas para o fechamento da ferida traumática extensa.

Treating complex wounds with great loss of soft tissues is a challenge for plastic surgery, especially when the wound is infected. Several options are considered for treatment, such as sutures, grafts, flaps, and expanders. Due to the complexity of the cases, the frequent association of morbidities, the need for multidisciplinary interventions, and long hospital stays, treatment costs are often high. This work demonstrates the elastic suture technique used in a clinical case, using continuous skin traction in association with a vacuum dressing, which enabled patient rehabilitation without the need for more aggressive interventions to close the extensive traumatic wound.

RESUMO Objetivo: Investigar a relação entre dispositivos de ventilação não invasiva e incidência de lesão do septo nasal em recém-nascidos pré-termo. Métodos: Este estudo de coorte retrospectivo e unicêntrico incluiu prematuros em uso de ventilação não invasiva. A incidência de lesão nasal foi comparada entre três grupos, de acordo com o dispositivo de ventilação não invasiva (G1 para máscara nasal; G2 para prongas binasais e G3 para alternância entre máscaras e prongas nasais). As lesões nasais foram classificadas de acordo com o National Pressure Ulcer Advisory Panel como estágios 1 - 4. Foram realizadas análises de regressão multivariada para estimar os riscos relativos, a fim de identificar possíveis preditores associados a lesões relacionadas a dispositivos médicos. Resultados: Entre os 300 lactentes incluídos no estudo, a incidência de lesões relacionadas a dispositivos médicos no grupo em uso alternado foi significativamente menor do que a nos grupos de máscara ou prongas de uso contínuo (n = 68; 40,48%; valor de p < 0,01). O grupo de prongas nasais apresentou mais lesões de estágio 2 (n = 15; 55,56%; p < 0,01). A permanência ≥ 7 dias em ventilação não invasiva foi associada a maior incidência de lesões relacionadas a dispositivos médicos, independentemente do dispositivo (63,81%; p < 0,01). Os incrementos diários na ventilação não invasiva aumentaram o risco de lesões nasais em 4% (IC95% 1,02 - 1,06; p < 0,01). Um maior peso ao nascer indicou proteção contra lesões relacionadas a dispositivos médicos. Cada grama extra representou diminuição de 1% no risco de desenvolver lesão do septo nasal (RR: 0,99; IC95% 0,99 - 0,99; p < 0,04). Conclusão: A alternância entre máscaras e prongas nasais reduz a incidência de lesão nasal moderada a grave em comparação com dispositivos únicos. O incremento de dias em uso de ventilação não invasiva parece contribuir para lesões relacionadas a dispositivos médicos, e um maior peso ao nascer é um fator de proteção.

ABSTRACT Objective: To investigate the association between noninvasive ventilation delivery devices and the incidence of nasal septum injury in preterm infants. Methods: This retrospective singlecenter cohort study included preterm infants supported by noninvasive ventilation. The incidence of nasal injury was compared among three groups according to the noninvasive ventilation delivery device (G1 - nasal mask; G2 - binasal prongs; and G3, rotation of nasal mask with prongs). Nasal injury was classified according to the National Pressure Ulcer Advisory Panel as stages 1 - 4. Multivariate regression analyses were performed to estimate relative risks to identify possible predictors associated with medical device-related injuries. Results: Among the 300 infants included in the study, the incidence of medical device-related injuries in the rotating group was significantly lower than that in the continuous mask or prong groups (n = 68; 40.48%; p value < 0.01). The basal prong group presented more stage 2 injuries (n = 15; 55.56%; p < 0.01). Staying ≥ 7 days in noninvasive ventilation was associated with a higher frequency of medical device-related injuries, regardless of device (63.81%; p < 0.01). Daily increments in noninvasive ventilation increased the risk for nasal injury by 4% (95%CI 1.02 - 1.06; p < 0.01). Higher birth weight indicated protection against medical device-related injuries. Each gained gram represented a decrease of 1% in the risk of developing nasal septum injury (RR: 0.99; 95%CI 0.99 - 0.99; p < 0.04). Conclusion: Rotating nasal masks with nasal prongs reduces the incidence of moderate to severe nasal injury in comparison with single devices. The addition of days using noninvasive ventilation seems to contribute to medical device-related injuries, and higher birth weight is a protective factor.

Clinical data of 14 patients with skin and soft tissue defects treated by progressive stretch skin suture (stretch suture) in Zhongnan Hospital of Wuhan University from September 2016 to January 2021 were retrospectively analyzed. There were 10 male and 4 female aged 13-73 years. The ankle and calf were the main defect sites with the defect area ranged from 2-3 cm×2-3 cm to 3-6 cm×5-9 cm. According to the wound skin condition, patients received progressive stretch suture 2-4 times after debridement and anti-infection treatment until the wounds were completely healed. Two patients with fractures underwent skin stretch after fracture fixation with external fixators. There were 4 patients with wound infection, including 2 cases infected with Staphylococcus aureus, 1 with Escherichia coli, and 1 with Enterobacter cloacae, all of whom received antibiotic therapy and infection was controlled and the progressive stretch suture was performed. In 3 patients with severe degloved skin injury, the infection was treated with debridement on the first day, and stretch suture was not performed until the second debridement. The soft tissue defect wound healed completely in 10-23 days, with an average of (17.2±3.8)days. None of the patients had skin necrosis during the stretch suture treatment. The postoperative follow-up time was more than 6 months and the skin softness, sensory function and blood supply of the patients were normal, and the average Vancouver Scar Scale score was 3.1, among whom 9 cases were scored as excellent (0-3 points) and 5 as good (4-7 points). The patients were satisfied with the effect of skin stretch,the study suggests that the progressive stretch skin suture technique is simple and effective in treatment of soft tissue defect.

Objective:To investigate the effect of inferior epigastric artery perforator flap transplantation in repairing traumatic soft tissue defects of lower limbs.Methods:A retrospective case series study was conducted to analyze the clinical data of 34 patients with traumatic soft tissue defects of lower limbs admitted to Chongqing Great Wall Hospital from January 2019 to May 2021, including 31 males and 3 females; aged 12-65 years [(38.5±5.6)years]. There were 8 patients with defects on the calf and 26 on the ankle. All wounds were found with exposed tendons, muscles and/or bones. The area of soft tissue defects ranged from 10 cm×6 cm to 40 cm×11 cm. All patients were repaired with inferior epigastric artery perforator flap. The wound healing, flap survival and recovery were observed. The visual analogue scale (VAS) and American Orthopedic Foot and ankle Society (AOFAS) ankle-hindfoot score were used to evaluate pain and ankle function before operation and at 3 days, 7 days, 14 days, 1 month, 3 months, 6 months and 12 months after operation. The complications were observed.Results:All patients were followed up for 12-36 months [(19.5±5.3)months]. All wounds were healed by stage I, showing the healing time of 14-24 days [(17.6±2.8)days]. All flaps survived with good color, soft texture and satisfactory appearance, with no obvious swelling. All flaps produced protective sensation. The VAS was (4.3±0.8)points, (3.3±0.7)points, (1.4±0.5)points, (1.2±0.3)points, (0.8±0.2)points and (0.4±0.1)points at 7 days, 14 days, 1 month, 3 months, 6 months and 12 months after operation, decreased gradually from preoperative (7.4±1.3)points (all P<0.05). The AOFAS ankle-hindfoot score was (35.6±3.1)points, (42.6±3.6)points, (50.3±4.3)points, (56.2±5.6)points, (60.3±6.8)points and (65.3±9.0)points at 7 days, 14 days, 1 month, 3 months, 6 months and 12 months after operation, increased from preoperative (22.4±2.5)points (all P<0.05). The ankle function was excellent in 25 patients, good in 5 and fair in 4 at 12 months after operation, with an excellent and good rate of 88.2%. Venous crisis occurred in 3 patients after operation, and the flaps survived completely after venous reanastomosis or venous bridging. Conclusion:For traumatic soft tissue defects of lower limbs, inferior epigastric artery perforator flap transplantation has advantages of enhanced survival of flaps, satisfactory appearance, attenuated pain, good functional recovery and few complications.
