Resultados da imaginação motora no fortalecimento muscular em membro inferior de uma pessoa com sequela pós acidente vascular cerebral: estudo de caso / Results of motor imagination in muscle strengthening of the lower limb in hemiplegia after stroke: case report

A Imaginação Motora (IM) é a representação mental de um ato motor sem a execução real do movimento, e ativa as mesmas áreas cerebrais do movimento real, mesmo na presença de paralisia, perda de membro ou visão, podendo ser utilizado no processo de conservação e estimulação de engramas cerebrais no processo de recuperação motora de um membro paralisado. Método: Homem, 34 anos, hemiplegia direita pós Acidente Vascular Cerebral (AVC) isquêmico. Realizou exercícios com profissional de Educação Física, duas vezes/semana, 50 minutos/sessão, durante 19 semanas, além do programa convencional de reabilitação multidisciplinar. A intervenção baseou-se na IM para flexão e extensão do joelho do lado paralisado, seguida da tentativa do mesmo movimento ativo. Resultados: Amplitude de movimento ativa (ADM_A) dos flexores do joelho direito iniciou em 217° com carga mínima do equipamento (5 kg). Em seguida, o profissional solicitava ao paciente que imaginasse que estava realizando o movimento e depois tentasse realizá-lo. Após 19 semanas, a ADM_A foi de 112°. Conclusão: Ganhos em ADM_A de 8,48° para a flexão de joelho do hemicorpo paralisado representa uma diferença mínima clinicamente importante em pacientes pós-AVC. A IM aumenta a demanda cognitiva nas áreas motoras cerebrais, aumentando a plasticidade, resultando em ganhos motores que impactam no prognóstico de capacidade e funcionalidade, justificando seu uso como método de treinamento na recuperação pós-AVC. A IM associada ao treinamento de força na reabilitação contribui para a recuperação de sequelas pós-AVC.

Motor Imagination (MI) is the mental representation of a motor act without the actual execution of the movement. It activates the same brain areas as real movement, even in the presence of paralysis, missing limb or vision, and can be used in the process of conserving and stimulating brain engrams in the process of motor recovery of a paralyzed limb. Method: We report a 34-year-old patient with right hemiplegia due to ischemic stroke. He performed exercises with a Physical Educator professional, twice a week, 50 minutes/session, for 19 weeks, in addition to the conventional multidisciplinary rehabilitation program. The intervention was based on MI for flexion and extension of the knee on the paralyzed side, followed by the attempt of the same active movement. Results: Active range of motion (ROM_A) of the right knee flexors started at 217° with the minimum equipment load (11 lbs). Then, the professional asked the patient to imagine that he was performing the movement and then try to perform it. After 19 weeks, ROM_A was 112° Conclusion: The ROM_A gain of 8.48° for knee flexion of the paralyzed hemibody represents a clinically important minimal difference in post-stroke patients. MI increases the cognitive demand on the brain's motor networks, increasing plasticity, resulting in motor gains that impact the prognosis of capacity and functionality, justifying its use as a training method in post-stroke recovery. MI associated with strength training in rehabilitation contributes to the recovery of post stroke sequelae.

Funcionalidad del miembro inferior con exposición ósea con el uso de terapia con presión negativa VAC® vs. colgajo de gemelo medial

Objetivo: Comparar dos técnicas de cirugía reconstructiva para lesión en miembro inferior con exposición ósea y, a través de ella, diferenciar que la técnica de VAC® (Vacuum Assisted Closure, cierre asistido con presión negativa) es una alternativa con beneficio de recuperación potencial sin alteraciones significativas que pudieran llevar a un compromiso funcional. Materiales y métodos: Estudio de tipo analítico con corte prospectivo, cuantitativo y longitudinal, en el que se desarrolló la terapia con el uso del sistema de VAC® y de colgajo gemelar medial en todos los pacientes de la Clínica Stella Maris que presentaron heridas traumáticas de miembro inferior con exposición ósea de tercio medio tibial durante el periodo 2019. Resultados: Se evidenció que la medición con la escala funcional de la marcha (FAC, por sus siglas en inglés) fue mejor en los pacientes con la técnica de VAC® (dado que el 50 % tiene grado V) respecto a la técnica de colgajo (50 % en grado IV); las diferencias fueron estadísticamente significativas (p < 0,05). Se apreció que el tiempo de cierre fue mayor en la técnica de VAC® debido al proceso de regeneración progresiva hasta llenar o cubrir la zona completa de la lesión; por otro lado, se evidenció la diferencia de la intensidad del dolor posoperatorio entre las dos técnicas: de moderado a intenso con la técnica de colgajo y leve, en su mayoría, con la técnica de VAC®. Conclusiones: El sistema de aspiración VAC® es eficiente para la cobertura ósea en defectos traumáticos del tercio medio tibial anterior, por lo que constituye una alternativa con potencial beneficio de recuperación sin alteración de estructuras anatómicas, ya que brinda mejores resultados funcionales y menores complicaciones. Es una opción útil que actúa de forma segura porque estimula el cierre de la herida y minimiza las necesidades de un tratamiento quirúrgico.

Objective: To compare two reconstructive surgery techniques for lower limb injury with exposed bone and demonstrate that the VAC® (vacuum-assisted closure) negative pressure wound therapy is an alternative for potential recovery showing no significant changes that could lead to functional compromise. Materials and methods: An analytical, prospective, quantitative and longitudinal study conducted with all the patients of Clínica Stella Maris with traumatic injuries of the lower limb and exposure of the middle third of the tibia treated with the VAC® system and the medial calf flap in 2019. Results: The measurement obtained with the functional ambulation categories (FAC) scale showed better results among the patients treated with the VAC® technique (since 50 % got grade V) than those who underwent the flap technique (50 % got grade IV), being the differences statistically significant (p < 0.05). It was observed that the time to closure was longer with the VAC® technique due to the progressive regeneration process consisting of the complete filling or coverage of the lesion area. On the other hand, the difference in the postoperative pain intensity between the two techniques was evident, being moderate to intense with the flap technique and mild, for the most part, with the VAC® technique. Conclusions: The VAC® suction system is effective for bone coverage in traumatic defects of the anterior middle third of the tibia. It is an alternative for potential recovery that does not change the anatomical structures because it provides better functional results and fewer complications. It is a useful and safe option that stimulates wound closure and minimizes the need for surgical treatment.

A Study of Clinico-social Profile of Animal Bite Patients Attending the Antirabies Clinic of BRD Medical College, Gorakhpur

Background: Rabies is one of zoonotic viral disease, estimated to cause 59000 human deaths annually in over 150 countries, of which 20,000 are from India alone; about 40% of which are in children under the age of 15. Rabies though 100% fatal is preventable with post-exposure prophylaxis which includes wound washing, anti-rabies vaccination and rabies immunoglobulin. Objective: To describe the clinico-social profile of animal bite patients attending the anti-rabies clinic of BRD Medical College, Gorakhpur. Methodology: A cross-sectional study was conducted in the anti-rabies clinic of Nehru hospital, BRD Medical College, Gorakhpur from January 2022 to May 2022. Study participants were interviewed by using a pre-phrased, pre-designed and pre-tested questionnaire. Data regarding socio-demographic and clinical profile of the study participants following animal bite exposure was collected. Results: The total number of animal bite victims were 250, in which majority of them were males (76.77%) and highest percentage was of adult population (20-59 years). Maximum number of victims were from rural area (78.70%). 19.35% were working and 39.35% were students. 77.43% were category III bites and in 50.96% cases lower limb was the site of bite and dogs were responsible for 89.67% of the bites. 60.64% victims did not wash the wound properly before reaching the anti-rabies clinic. Conclusion: This study concludes that as majority of the animal bite victims were students and majority of victims were unaware about the importance of wound care, therefore a step can be taken to create awareness in various schools.

The performance in the 30-second sit and stand test showed a significant difference pre (6.8 ± 2.28) and post intervention (10.4 ± 1.67, p= 0.004). Conclusion: The lower limbs muscular resistance program was effective, as it increased functional physical performance with gains in muscle strength and endurance in hemodialysis patients

Correlation and predictive effect of subjective and objective balance function measurements in stroke patients with hemiplegia / 中国康复理论与实践

ObjectiveTo explore the correlation of index of standing balance tester to score of Berg Balance Scale (BBS) and Fugl-Meyer Assment-Lower Extremites (FMA-LE) in stroke patients with hemiplegia, and analyze the predictive effect to BBS. MethodsFrom March to October, 2022, 66 stroke hemiplegic patients in the Affiliated Hospital of Shandong University of Traditional Chinese Medicine were selected. The elliptical area and length of motion were measured with a balance tester when they were standing with eyes open or closed, respectively. They were also evaluated with BBS and FMA-LE. The correlation between the test results and the scores of BBS and FMA-LE was analyzed with Pearson's correlation analysis, and the predictive effect of the test results to the score of BBS was also analyzed with receiver operating characteristic (ROC) curve. ResultsHypertension, diabetes, coronary heart disease, smoking and alcohol drinking were not significant for the scores of BBS and FMA-LE (|t| < 1.124, P > 0.05). In the balance test, the eye opening movement ellipse area, eye opening movement length, eye closing movement ellipse area and eye closing movement length were negatively correlated with the scores of BBS and FMA-LE (|r| > 0.250, P < 0.05). The area under the ROC curve of eye opening movement ellipse area to the score of BBS was 0.685 (P = 0.019), and the area under the ROC curve of the eye opening movement length to the score of BBS was 0.764 (P < 0.001). ConclusionThe open eye movement ellipse area, open eye movement length, closed eye movement ellipse area and closed eye movement length are significantly negatively correlated with the scores of BBS and FMA-UE. The indexes of the balance test with eyes open may predict the score of BBS.

Effect of esketamine on extremity ischemia-reperfusion-induced lung injury in elderly patients undergoing total knee replacement / 中华麻醉学杂志

Objective:To evaluate the effect of esketamine on extremity ischemia-reperfusion-induced lung injury in elderly patients undergoing total knee replacement.Methods:Sixty elderly patients of both sexes, aged 65-80 yr, with body mass index <35 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective unilateral total knee replacement under neuraxial anesthesia, were divided into 2 groups according to the random number table method: control group (C group) and esketamine group (S group), with 30 cases in each group. Esketamine 0.3 mg/kg was intravenously infused before tourniquet inflation in group S. Immediately after the end of operation, the two groups received adductor block with 0.5% ropivacaine 15 ml under ultrasound guidance. And then patient-controlled intravenous analgesia was performed, patient-controlled intravenous analgesia solution included sufentanil 1.5 μg/kg in 100 ml of normal saline in group C and sufentanil 1.5 μg/kg and esketamine 0.75 mg/kg in 100 ml of normal saline in group S. The background infusion rate was 1.5 ml/h, the patient-controlled analgesia dose was 1.5 ml, and the lockout interval was 15 min in the two groups. When the visual analogue scale score at rest≥ 4 points within 3 days after surgery, ketorolac tromethamine 30 mg was intravenously injected for rescue analgesia. Blood samples from the radial artery were collected for blood gas analysis at 30 min before tourniquet inflation(T 0), 30 min after tourniquet inflation(T 1), and 3 min, 30 min and 24 h (T 4) after tourniquet release (T 2-4), and PaO 2 and PaCO 2 were recorded. The alveola-arterial oxygen partial pressure difference, oxygenation index and respiratory index were calculated. Peripheral venous blood samples were collected at T 0, T 3 and T 4 for determination of serum endothelin-1 and malondialdehyde by enzyme-linked immunosorbent assay. The requirement for rescue analgesia and occurrence of dizziness, hallucinations and pulmonary complications within 3 days after surgery were recorded. Results:Compared with group C, alveola-arterial oxygen partial pressure difference was significantly decreased at T 1-3, respiratory index was decreased, oxygenation index was increased at T 2, 3, and serum endothelin-1 and malondialdehyde concentrations were decreased at T 3, 4, and the rate of postoperative rescue analgesia was decreased in group S( P<0.05). There was no significant difference in the incidence of postoperative dizziness, hallucinations, and pulmonary complications between the two groups ( P>0.05). Conclusions:Esketamine can reduce extremity ischemia-reperfusion-induced lung injury in elderly patients undergoing total knee replacement, and the mechanism may be related to regulating vascular endothelial function and reducing lipid peroxidation.

The treatment of 3D-printed metal prostheses on bone defect of malignant bone tumors in lower limbs / 中华骨科杂志

Objective:To investigate the early and middle term clinical efficacies of 3D-printed metal prostheses in the reconstruction of bone defects after osteotomy in malignant bone tumors.Methods:A total of 34 patients with malignant bone tumors of lower extremity femur and tibia who underwent 3D printing individualized metal prosthesis replacement surgery in the Department of Bone and Soft Tissue of Affiliated Cancer Hospital of Zhengzhou University from March 2019 to March 2022 were retrospectively analyzed. There were 23 males and 11 females, with an average age of 19.1±15.2 years (range, 7-80 years). There were 22 children and adolescents younger than 18 years old. There were 3 cases in the proximal femur, 15 cases in the middle and distal femur, 10 cases in the proximal tibia and 6 cases in the distal tibia. According to the final pathological diagnosis, 24 cases of osteosarcoma, 6 cases of Ewing's sarcoma, 2 cases of undifferentiated sarcoma, 1 case of osteosarcoma, and 1 case of malignant giant cell tumor of bone were enrolled in this study. Postoperative complications, wound healing, periprosthetic fracture and aseptic loosening, tumor outcome (evaluated by tumor control evaluation criteria), and length difference of lower limbs were recorded. Response evaluation criteria in solid tumor (RECIST) was used to evaluate tumor outcomes. Prosthetic-bone interface healing was evaluated postoperatively, and the function was evaluated based on Musculoskeletal Oncology Society (MSTS) 93.Results:The length of lesions was 70-240 mm in 34 patients, with an average of 125.5±35.4 mm. The length of osteotomy was 80-275 mm, with an average of 160.2±33.9 mm. No tumor was found on the osteotomy surface. The customized prosthesis was firmly installed and closely matched with the side of the preserved articular surface. There were 2 patients with local incision fat liquefaction and 4 patients with superficial wound infection, which healed after debridement and antibiotic treatment. One distal tibia osteosarcoma case developed severe periprosthetic infection 2 months after surgery, resulting in prosthesis implantation failure, limb movement pain and poor ankle function. After removal of the prosthesis, infection control and osteogenesis with the Ilizarov technique, the infection was completely controlled and local osteogenesis was possible. The remaining 33 patients had a good prosthetic-bone interface union. One case was found to have localized bone resorption on the contact surface of the prosthesis 7 months after operation, but the metal prosthesis and screws were not loose. The incisions healed well in other patients, without infection, prosthesis loosening, fracture or other complications. All patients survived and were followed up for 13.8±5.6 months (range, 7-27 months). During the follow-up, there was no recurrence of tumor at the osteotomy end in all patients, but 5 patients developed lung metastasis. At the end of the last follow-up, all patients survived. Among them, 16 patients had unequal length of lower limbs, including 10 cases within 2 cm, 3 cases between 2-5 cm, and 3 cases over 5 cm. With the exception of one patient whose prosthesis was removed due to infection, the MSTS 93 of the other patients was 24.9±2.2 (range, 19-28), and were rated as excellent in 26 cases and good in 7 cases. According to the RECIST evaluation criteria, 26 of 34 patients had complete response, 5 had disease progression, and 3 had stable disease.Conclusion:3D printed metal prosthesis is one of the effective methods for the treatment of bone defects after resection of malignant bone tumors in lower limbs, which is safe, reliable and has satisfactory early curative effect.

Comparison of bone transport technique combined with bone grafting plus internal fixation versus simple bone transport technique for large segmental bone defects at lower limbs after trauma / 中华创伤骨科杂志

Objective:To compare the clinical efficacy between bone transport technique combined with bone grafting plus internal fixation and simple bone transport technique in the treatment of large segmental bone defects at lower limbs after trauma.Methods:A retrospective study was conducted to analyze the clinical data of 42 patients with large segmental bone defects at lower limbs after trauma who had been treated at Department of Trauma Orthopaedics, Honghui Hospital Affiliated to Medicine College, Xi'an Jiaotong University from September 2015 to September 2019. The patients were divided into 2 groups according to the different methods of repairing bone defects. In group A of 18 patients subjected to bone transport combined with bone grafting plus internal fixation, there were 11 males and 7 females with an age of (35.2±10.3) years, and 12 tibial defects and 6 femoral defects; in group B of 24 patients subjected to simple bone transport, there were 15 males and 9 females with an age of (37.3±9.4) years, and 17 tibial defects and 7 femoral defects. The external fixation time (EFT), external fixation index (EFI), total cure time and complications were recorded and compared between the 2 groups. At the last follow-up, the Ennecking score for limb functional recovery (score/total score 30) and Self-rating Anxiety Scale (SAS) were used to evaluate respectively the functional recovery of the limbs and postoperative anxiety.Results:The 2 groups were comparable because there was no significant difference between them in preoperative general data or follow-up time ( P>0.05). There was no statistically significant difference in the number of surgeries between the 2 groups ( P>0.05). The EFT [(5.9±1.5) months], EFI [(0.45±0.09) months/cm], total treatment time [(16.2±2.4) months], Ennecking score for limb functional recovery (87.0%±8.6%), SAS score [(43.2±9.0) points], and complications per capita [(0.4±0.2) times/case] in group A were significantly better than those in group B [(15.3±4.2) months, (1.19±0.28) months/cm, (19.7±3.5) months, (77.3%±9.2%), (58.2±9.3) points, and (1.2±0.5) times/case] (all P<0.05). Conclusion:In the treatment of large segmental bone defects at lower limbs, compared with simple bone transport technique, bone transport technique combined with bone grafting plus internal fixation has advantages of shorter external fixation time and overall cure time, a lower rate of complications, and better functional recovery of the limbs.

A wound diagnosis and treatment mode with integrated medical care for repair of chronic infectious wounds plus bone exposure at lower extremities / 中华创伤骨科杂志

Objective:To evaluate a wound diagnosis and treatment mode with integrated medical care in the repair of chronic infectious wounds plus bone exposure at lower extremities.Methods:A retrospective analysis was conducted of the 64 patients with chronic infectious wound plus bone exposure at the lower 1/3 of the leg who had been admitted to Department of Orthopedics Trauma and Microsurgery, Zhongnan Hospital of Wuhan University from January 2019 to December 2021. The patients were divided into 2 groups according to the wound diagnosis and treatment mode. In the observation group of 31 patients subjected to the wound diagnosis and treatment mode with integrated medical care led by specialist nurses, there were 24 males and 7 females with an age of (53.6±12.4) years, the wound was located at the tibial side in 15 cases and at the fibular side in 16 cases, the wound areas averaged [28.27 (23.56, 37.70) cm 2], and the time from injury to treatment was (27.3±4.1) d. Evaluation of the patient's condition, wound diagnosis and formulation of treatment protocols were performed jointly by a doctor-nurse team after the patients were admitted, and continuous diagnosis and treatment of the wounds were carried out mainly by specialist nurses during the doctors' follow-up. In the control group of 33 patients subjected to the conventional wound diagnosis and treatment mode led by doctors, there were 25 males and 8 females with an age of (51.3±14.3) years, the wound was located at the tibial side in 17 cases and at the fibular side in 16 cases, the wound areas averaged [27.49 (17.84, 40.45) cm 2], and the time from injury to treatment was (27.6±4.0) d. The 2 groups were compared in the wound healing rate, wound recurrence rate, hospitalization time and patients' satisfaction. Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). The observation group achieved a significantly higher wound healing rate within 1 month after treatment [83.87% (26/31)] than the control group [60.61% (20/33)], a significantly lower wound recurrence rate within 6 months after treatment [0% (0/31)] than the control group [18.18% (6/33)], significantly shorter hospitalization time [18.0 (15.1, 20.9) d] than the control group [26.8 (18.4, 40.1) d], and significantly higher patients' satisfaction [50 (50, 50) points] than the control group [50 (42, 50) points] (all P<0.05). Conclusion:In the repair of chronic infectious wounds plus bone exposure at lower extremities, the wound diagnosis and treatment mode with integrated medical care led by specialist nurses may result in a higher wound healing rate, a lower wound recurrence rate, a shorter hospital stay and higher patients' satisfaction than the conventional wound diagnosis and treatment mode led by doctors.

Thromboelastogram for early diagnosis of deep vein thrombosis after free flap surgery of lower extremity / 中华创伤骨科杂志

Objective:To investigate the clinical value of thromboelastogram in early diagnosis of deep vein thrombosis (DVT) in patients undergoing free flap surgery of lower extremity.Methods:A retrospective study was conducted to analyze the 192 patients undergoing surgical repair of soft tissue defects at lower extremity with free anterolateral femoral flap at Department of Orthopaedics, Tongji Hospital from January 2018 to June 2022. There were 117 males and 75 females, with an age of (45.6±12.7) years and an area of skin defects ranging from 5 cm × 3 cm to 18 cm × 9 cm. The patients were divided into 2 groups according to whether DVT occurred on the first day after surgery. In the DVT group of 22 patients, there were 14 males and 8 females, with an age of (47.7±14.3) years; in the DVT-free group of 170 patients, there were 103 males and 67 females, with an age of (45.3±12.5) years. The 2 groups were compared in terms of reaction time, coagulation time, maximum amplitude and coagulation angle in the thromboelastogram. Diagram of receiver operating characteristic (ROC) curves was used to evaluate the predictive value of thromboelastography in assessing the risk of DVT after surgery.Results:The 2 groups were comparable because there was no significant difference in the baseline information or operation time between them ( P>0.05). The reaction time [(5.21±0.85) min] and coagulation time [(1.12±0.30) min] in the DVT group were significantly shorter than those in the DVT-free group [(6.48±0.06) min and (1.60±0.03) min], and the maximum amplitude [(71.45±1.17) mm] and coagulation angle [69.54° (64.59°, 76.64°) ] in the DVT group were significantly larger than those in the DVT-free group [(66.63±0.40) mm and 64.92°(54.11°, 74.21°)] (all P<0.05). The optimal cut-off points in the ROC diagram were 5.46 min at reaction time, 1.52 min at coagulation time, 72.31 mm at maximum amplitude and 59.89° at coagulation angle. The sensitivity and specificity of detecting DVT on the first day after surgery were 80.7% and 71.6%, respectively, according to the combination of the best cut-off points in the ROC diagram and all the indexes in the thromboelastogram. Conclusion:Thromboelastogram is of a great value for the diagnosis of lower extremity DVT, and of a positive significance for the prevention of serious complications after surgery in patients undergoing free flap surgery of lower extremity.

Clinical application of adjustable traction skin stretchers in repair of wounds at the lower leg, foot and ankle / 中华创伤骨科杂志

Objective:To evaluate the clinical effects of adjustable traction skin stretchers used in repair of wounds at the lower leg, foot and ankle.Methods:A retrospective study was performed to analyze the clinical data of 56 patients who had been treated for skin defects at the lower leg, foot and ankle from August 2016 to September 2022 at The First Affiliated Hospital of Zhengzhou University, Honghui Hospital, Affiliated to Xi'an Jiaotong University Medical College, The First Affiliated Hospital of Henan Polytechnic University, and Yunnan Zhongde Orthopedic Hospital. There were 35 males and 21 females, aged (39.9±18.7) years. There were 43 traumatic wounds, 3 burns, 6 inflammatory wounds, 3 relief incisions due to osteofascial compartment syndrome, and 1 scar. The areas of skin defect ranged from 2.5 cm × 2.0 cm to 20.0 cm × 10.0 cm. The duration of wounds was (8.6±7.8) d. All the wounds were repaired with adjustable traction skin stretchers. The row-hook type of skin stretchers was used in 28 cases, the single-rod type in 20 cases, the single-rod type combined with an external fixator in 5 cases, and a combination of the row-hook type and the single-rod type in 3 cases.The time for wound traction closure, color of wound skin margin, skin swelling around the wound, functional recovery of affected limb and complications were recorded.Results:The time from skin stretching to wound closure was (7.8±3.8) d in the 56 patients. The color of wound skin edge after stretching was normal in 16 cases, dark red in 38 cases, and dark in 2 cases; the skin swelling around the wound was degree 1 in 21 cases, degree 2 in 33 cases, and degree 3 in 2 cases. The 56 patients were followed up for (8.9±4.1) months. Primary wound closure was achieved in 48 patients, and secondary wound closure in 8 patients after repair with an autologous skin graft. Partial skin necrosis occurred due to tension blisters after skin stretching in 2 patients, one of whom was repaired with an autologous skin graft and the other of whom by dressing change. Deep bone infection recurred in 2 patients whose wounds healed after their bone defects were repaired using Ilizarov technique of bone transfer. In the 56 patients, the muscle strength of the lower extremity beyond the wound was recovered to normal, and the range of motion of the joints adjacent to the wound also recovered to normal.Conclusion:In repair of wounds at the lower leg, foot and ankle, adjustable traction skin stretchers can lead to fine clinical effects and limited complications, because the stretchers can control the tension of skin digitally and precisely.

Application of artificial intelligence based on neural network radiation field in repair of soft tissue defects at lower limbs / 中华创伤骨科杂志

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.

Ultrasound findings and related factors of lower extremity arterial disease in patients with type 2 diabetes mellitus / 中国基层医药

Objective:To investigate the value of ultrasound findings in the diagnosis of lower extremity arterial disease in patients with type 2 diabetes mellitus and correlate it with clinical factors.Methods:A total of 535 patients with type 2 diabetes mellitus who received treatment in Taiyuan Second People's Hospital from January 2016 to June 2019 underwent color Doppler ultrasound examination (T2DM group). Vascular inner diameter, intima-media thickness, atherosclerotic plaque formation, lumen stenosis or occlusion, and hemodynamic characteristics were determined in patients with type2 diabetes mellitus compared with those in 107 patients with non-type 2 diabetes mellitus (non-T2DM group). These parameters were correlated with the course of the disease, blood glucose level, concomitant hypertension or not, and clinical Wagner grade.Results:The incidences of intima-media thickening, atherosclerotic plaque, stenosis, and occlusion of lower extremity arteries were 69.9%, 89.0%, 77.0% and 11.6% respectively, in the T2DM group, which were significantly higher than 41.1%, 78.5%, 72.0%, and 1.9% respectively in the non-T2DM group ( χ2 = 32.52, P < 0.001; χ2 = 8.76, P = 0.003; χ2 = 27.77, P < 0.001). With the prolongation of the course of T2DM, the incidence of arterial lesions in the lower extremities increased ( P < 0.001). The incidences of intima-media thickening, atherosclerotic plaque, stenosis, and occlusion of lower extremity arteries were significantly greater in the poor blood glucose control group and non-hypertension group compared with the good blood glucose control group and hypertension group (all P < 0.05). The degree of lower extremity arterial stenosis in T2DM patients was related to Wagner's grade. As the degree of stenosis increased, Wagner's grade increased correspondingly and significantly ( P < 0.001). Conclusion:Color Doppler ultrasound examination has an important value in evaluating lower extremity arterial lesions in patients with T2DM. The degree of arterial lesions in the lower extremities of T2DM patients is correlated with the course of the disease, blood glucose levels, concomitant hypertension, and clinical Wagner grade. Color Doppler ultrasound examination has an important clinical significance in evaluating the degree of vascular lesions and guiding early interventions in the clinic.

Objective:To study the clinical application of hanging moxibustion in intervention of deep venous thrombosis (DVT) of lower extremity after intertrochanteric fracture of femur, in order to provide theoretical basis for the clinical application of suspension moxibustion.Methods:By adopting a controlled clinical trial method, a total of 100 patients with femoral intertrochanteric fracture who came to Keqiao District Hospital of Traditional Chinese Medicine, Shaoxing City, Zhejiang Province for orthopaedic surgery from January 2021 to September 2022 were selected by convenient sampling method and randomly divided into the control group and the observation group, 50 cases in each group. The control group was given routine nursing intervention, and the observation group was given the traditional Chinese medicine nursing intervention of hanging moxibustion on the basis of the control group. The changes of coagulation function indexes, hemorheology indexes, hemodynamics, the swelling degree score of the affected limb, and the Visual Analogue Scale (VAS) of the affected limb pain in the two groups of patients with intertrochanteric fracture before and 14 days after the intervention, and the incidence of lower extremity deep venous thrombosis (DVT) in the two groups after 1 d, 3 d, 7 d, and 14 d of intervention were observed and recorded.Results:After 14 days of intervention, D-dimer, fibrinogen and prothrombin time in the observation group were (380.64 ± 41.78) μg/L, (4.51 ± 0.49) g/L and (10.46 ± 1.04) s, respectively, which were better than those in the control group (464.91 ± 46.81) μg/L, (4.82 ± 0.56) g/L and (12.85 ± 1.12) s with statistical difference ( t=9.50, 2.95, 11.06, all P<0.05). After 14 days of intervention, the whole blood low tangential viscosity, whole blood high tangential viscosity and plasma viscosity in the observation group were (8.34 ± 0.42), (3.72 ± 0.28) and (1.21 ± 0.18) mPa/s, respectively, which were significantly lower than (8.90 ± 0.46), (4.13 ± 0.26) and (1.53 ± 0.22) mPa/s in the control group ( t=6.36, 7.59, 7.96, all P<0.05). After 14 days of intervention, the postoperative blood flow, maximum blood flow velocity and average blood flow velocity in the observation group were (1.89 ± 0.26) L/min, (31.57 ± 3.29) cm/s, (34.41 ± 3.62) cm/s, which were significantly higher than (1.45 ± 0.21) L/min, (24.18 ± 2.85) cm/s, (27.96 ± 3.15) cm/s in the control group ( t=9.31, 12.01, 9.50, all P<0.05). After 14 days of intervention, the total incidence of lower limb DVT in the observation group was 2.00%(1/50) , lower than 24.00%(12/50) in the control group, the difference between the two groups was significant ( χ2=10.70, P<0.05). Conclusions:Suspended moxibustion can significantly improve the coagulation function, hemorheology, hemodynamics, swelling and pain of the affected limb in patients with postoperative intertrochanteric fracture of the femur, and reduce the occurrence of DVT in the lower extremity. It is recommended to be widely used in clinical practice.
