Is ankle taping effective to limit the ankle dorsiflexion in a single-training session? An observational study in semi-professional basketball players

ABSTRACT BACKGROUND: Ankle taping (AT) is effective in preventing ankle sprain injuries in most common sports and is employed in rehabilitation and prevention sports. OBJECTIVE: This study aimed to investigate the effectiveness of AT to restricting excessive frontal plane ankle movements in semi-professional basketball players throughout the training session. DESIGN AND SETTING: A cross-sectional study was performed at the Universidad Europea de Madrid. METHODS: Forty male and female semi-professional basketball players were divided into two groups. The ankle dorsiflexion range of motion (ROM) and interlimb asymmetries in a weight-bearing lunge position were evaluated at four time points: 1) with no tape, 2) before practice, at 30 min of practice, and 3) immediately after practice. RESULTS: In male basketball players, no differences were observed in the right and left ankles between the baseline and 30 min and between baseline and 90 min of assessment. In female athletes, significant differences were reported between baseline and pre-training assessments for the right ankle and also significant differences between baseline and 90 min in both ankles. CONCLUSIONS: Ankle taping effectively decreased the ankle dorsiflexion ROM in male and female basketball players immediately after application. However, ROM restriction was very low after 30 and 90 min, as assessed in a single basketball practice. Therefore, the classic taping method should be revised to develop new prophylactic approaches, such as the implementation of semi-rigid bracing techniques or the addition of active stripes during training or game pauses.

Uso de dispositivos móviles y alteraciones cervicales en estudiantes universitarios / Use of mobile devices and cervical disorders in university students / Uso de dispositivos móveis e distúrbios cervicais em estudantes universitários

Las alteraciones cervicales son un problema multifactorial que afecta a la sociedad moderna. Posturas viciosas, traumatismos y defectos congénitos relacionados con la columna cervical pueden desarrollar inestabilidad, pinzamiento radicular, cervicoartrosis y cervicalgias. Objetivo. Relacionar el uso de dispositivos móviles con las alteraciones cervicales en estudiantes universitarios. Materiales y métodos. Estudio descriptivo, observacional, que se realizó entre los meses de mayo y julio del 2023, cuya muestra fue de 172 estudiantes universitarios que se obtuvo aplicando la fórmula para el cálculo muestral de poblaciones conocidas, mediante un muestreo no probabilístico.

Risk Factors for Symptomatic Cyclops Lesion Formation after Anterior Cruciate Ligament Reconstruction / Fatores de risco para formação de lesão cyclops sintomática após a reconstrução do ligamento cruzado anterior

Abstract Objective To evaluate the incidence of symptomatic cyclops lesions requiring surgical treatment after anterior cruciate ligament (ACL) reconstruction and to establish possible intraoperative risk factors related to it. Methods Three hundred and eighty-nine patients aged between 18 and 50 years who underwent primary ACL reconstruction were retrospectively evaluated. Patients were divided into groups according to the presence or absence of symptomatic cyclops lesions, and their characteristics were compared. Patients with associated lesions that required additional surgical procedures (except anterolateral extra-articular procedures) were not included. The rate of symptomatic cyclops lesions was recorded and the following parameters were evaluated: age, gender, time from injury to surgery, graft type and diameter, femoral tunnel perforation technique, fixation type, presence of knee hyperextension, preservation of the ACL remnant, associated anterolateral extra-articular procedure, associated meniscal injury and participation in sports. Results 389 patients were evaluated and 26 (6.7%) patients developed cyclops. The patients with and without cyclops lesions did not differ in age, time from injury to surgery, graft type or diameter, surgical technique, femoral fixation method, presence of knee hyperextension, remnant preservation and associated meniscal injury. The group with cyclops lesion had a higher proportion of females (10 (38.4%) vs 68 (18.7%); OR = 2.7; p= 0.015), higher proportion of extra-articular reconstruction (18 (11.8%) vs 8 (3.4%); OR = 3.8; p= 0.001) and higher proportion of sports practice (23 (8.6%) vs 3 (2.5%); OR = 3.6; p= 0.026). Conclusion In our series, 6.7% of the patients required arthroscopic removal of cyclops lesions. Female gender, associated extra-articular reconstruction and sports practice were factors related to this lesion. Remnant preservation had no relationship with cyclops lesion formation.

Resumo Objetivo Avaliar a incidência de lesões cyclops sintomáticas que precisam de tratamento cirúrgico após a reconstrução do ligamento cruzado anterior (LCA) e estabelecer os possíveis fatores de risco intraoperatórios relacionados a elas. Métodos Trezentos e oitenta e nove pacientes com idades entre 18 e 50 anos submetidos à reconstrução primária do LCA foram avaliados de forma retrospectiva. Os pacientes foram divididos em grupos de acordo com a presença ou ausência de lesões cyclops sintomáticas e suas características foram comparadas. Não foram incluídos pacientes com lesões associadas que necessitassem de outros procedimentos cirúrgicos (à exceção de procedimentos extra-articulares ântero-laterais). A taxa de lesões cyclops sintomáticas foi registrada e os seguintes parâmetros foram avaliados: idade, sexo, tempo da lesão à cirurgia, tipo e diâmetro do enxerto, técnica de perfuração do túnel femoral, tipo de fixação, presença de hiperextensão do joelho, preservação do LCA remanescente, associação a procedimento extra-articular ântero-lateral, lesão de menisco associada e participação em esportes. Resultados Dos 389 pacientes avaliados, 26 (6,7%) desenvolveram lesão cyclops. Os pacientes com e sem lesão cyclops não diferiram quanto à idade, tempo da lesão à cirurgia, tipo ou diâmetro do enxerto, técnica cirúrgica, método de fixação femoral, presença de hiperextensão do joelho, preservação do LCA remanescente e lesão de menisco associada. O grupo com lesão cyclops apresentou mais mulheres (10 [38,4%] vs. 68 [18,7%]; razão de probabilidades [OR] = 2,7; p= 0,015), maior proporção de reconstrução extra-articular (18 [11,8%] vs. 8 [3,4 %]; OR = 3,8; p= 0,001) e maior proporção de prática esportiva (23 [8,6%] vs. 3 [2,5%]; OR = 3,6; p= 0,026). Conclusão Em nossa série, 6,7% dos pacientes necessitaram de remoção artroscópica das lesões cyclops. O sexo feminino, a reconstrução extra-articular associada e a prática esportiva foram fatores relacionados a essa lesão. A preservação do menisco remanescente não foi associada à formação de lesões cyclops.

Impaired flexibility in patients with tropical spastic paraparesis/HTLV-associated myelopathy: evaluation via pendulum fleximeter / Flexibilidade prejudicada em pacientes com paraparesia espástica tropical/mielopatia associada ao HTLV: avaliação via flexímetro pendular

Abstract Background Flexibility is crucial to the harmonious execution of joint movements. While skeletal muscle dysfunction in patients with HTLV-1 can interfere with mobility, it is unclear whether these patients experience reduced flexibility. Objective To evaluate the differences in flexibility between HTLV-1-infected individuals with and without myelopathy compared with uninfected controls. We also investigated whether age, sex, body mass index (BMI), physical activity level, or lower back pain influence flexibility in HTLV-1-infected individuals. Methods The sample consisted of 56 adults, of which 15 did not have HTLV-1, 15 had HTLV-1 without myelopathy, and 26 had TSP/HAM. Their flexibility was assessed using the sit-and-reach test and a pendulum fleximeter. Results No differences in flexibility were observed between the groups with and without myelopathy and controls without HTLV-1 infection using the sit-and-reach test. The pendulum fleximeter results of individuals with TSP/HAM presented the lowest flexibility among the groups with respect to trunk flexion, hip flexion and extension, knee flexion, and ankle dorsiflexion, even after adjusting for age, sex, BMI, level of physical activity, and lower back pain using multiple linear regression models. Additionally, HTLV-1-infected individuals without myelopathy demonstrated reduced flexibility in movements: knee flexion, dorsiflexion, and ankle plantar flexion. Conclusions Individuals with TSP/HAM demonstrated reduced flexibility in most of the movements evaluated by the pendulum fleximeter. Additionally, HTLV-1-infected individuals without myelopathy demonstrated reduced knee and ankle flexibility, potentially representing a marker of myelopathic development.

Resumo Antecedentes A flexibilidade é fundamental para a execução harmoniosa dos movimentos articulares. Embora a disfunção do músculo esquelético em pacientes com HTLV-1 possa interferir na mobilidade, não está claro se esses pacientes apresentam flexibilidade reduzida. Objetivo Avaliar as diferenças de flexibilidade entre os indivíduos infectados com e sem mielopatia e o grupo controle sem infecção HTLV-1. Também investigamos se idade, sexo, índice de massa corporal (IMC), nível de atividade física ou dor lombar influenciam a flexibilidade em indivíduos infectados pelo HTLV-1. Métodos A amostra foi composta por 56 adultos, dos quais 15 não possuíam HTLV-1, 15 possuíam HTLV-1 sem mielopatia e 26 possuíam TSP/HAM. A flexibilidade foi avaliada por meio do teste de sentar e alcançar e do flexímetro de pêndulo. Resultados Não foram observadas diferenças na flexibilidade entre os grupos com e sem mielopatia no teste de sentar e alcançar. Os resultados do flexímetro pendular dos indivíduos com TSP/HAM apresentaram a menor flexibilidade entre os grupos em relação à flexão do tronco, flexão e extensão do quadril, flexão do joelho e dorsiflexão do tornozelo, mesmo após ajuste para idade, sexo, IMC, nível de atividade física e dor lombar usando modelos de regressão múltipla linear. Além disso, os indivíduos infectados pelo HTLV-1 sem mielopatia demonstraram redução da flexibilidade nos movimentos de flexão do joelho, dorsiflexão e flexão plantar do tornozelo. Conclusão Indivíduos com TSP/HAM demonstraram redução da flexibilidade na maioria dos movimentos avaliados pelo flexímetro pendular. Além disso, indivíduos infectados pelo HTLV-1 sem mielopatia demonstraram redução da flexibilidade do joelho e tornozelo, representando potencialmente um marcador de desenvolvimento mielopático.

Evaluation of the rotary kinematics between actual and set speeds of X-Smart Plus, VDW.Silver and iRoot motors

Abstract The present study evaluated the actual rotational speed of three different endodontic motors compared to the values provided by the manufacturers. A total of three endodontic motors (X-Smart Plus, VDW.Silver, and iRoot) were tested at 400 rpm and 800 rpm and 2 N/cm2 torque. The kinematics of the devices was recorded by using a custom angle-measuring disc with a 50-mm diameter attached to the handpiece provided by the manufacturer, whereas their movement was captured by a high-speed camera at 2,400 frames per second, 800 x 800 pixel-resolution and distance of 0.3 m from the target object. Statistical analysis was performed at a significance level of 5%. At 400 rpm, the iRoot motor had a value of 17.94 rpm above that indicated by the manufacturer, which was significantly different from those of X-Smart Plus (5.20 rpm below that indicated by the manufacturer) and VDW.Silver (0.62 rpm above that indicated by the manufacturer) motors (P < 0.05). At 800 rpm, the iRoot motor had a value of 51.34 rpm below that indicated by the manufacturer, whereas the X-Smart Plus motor had a value of 13.00 rpm below that indicated by the manufacturer (P > 0.05). The VDW.Silver motor statistically differed from the iRoot and X-Smart Plus ones, showing a value of 1.68 rpm above that indicated by the manufacturer. In conclusion, the X-Smart Plus, VDW.Silver, and iRoot motors showed lower variations in the rotational speed values compared to those reported by their manufacturers. The endodontic motors presented different behaviors between them, with the VDW.Silver motor presents the most accurate values and the iRoot presents the most divergent values.

A análise estatística foi realizada com nível de significância de 5%. A 400 rpm, o motor iRoot apresentou 17,94 rpm acima do indicado pelo fabricante, sendo o valor significativamente diferente do X-Smart Plus (5,20 rpm abaixo do indicado pelo fabricante) e VDW.Silver (0.62 rpm acima do indicado pelo fabricante) (P > 0,05). A 800 rpm, iRoot apresentou 51.34 rpm abaixo do indicado pelo fabricante e X-Smart Plus 13,00 rpm abaixo do indicado pelo fabricante (P > 0,05). VDW.Silver foi estatisticamente diferente de iRoot e X-Smart Plus, apresentando 1,68 rpm acima do indicado pelo fabricante. Concluiu-se que os motores X-Smart Plus, VDW.Silver e iRoot apresentaram baixa variação na velocidade rotacional quando comparada ao fornecido pelo fabricante. Os motores endodônticos apresentaram diferentes comportamentos entre eles, sendo que o motor VDW.Silver apresentou valores mais acurados enquanto o iRoot foi o mais divergente.

A Case Study of Successful Ayurveda Management in the Patient of Migraine (Ardhavabhedaka) and Motion Sickness

Migraine is a type of Headache characterized by moderate to severe throbbing pain, generally associated with nausea, vomiting and light sensitivity. It can be correlated to Ardhavbhedaka, which according to the Ayurvedic science is caused by simultaneous vitiation of all the three Doshas viz. Vata, Pitta and Kapha. Motion sickness is also a common disorder wherein patient suffers from symptoms like nausea, vomiting, increased salivation, dizziness, upon getting triggered by certain movements. In this case study, a female patient of middle age group (Madhyam Avastha) suffering from long standing migraine and motion sickness since past 15 years (on and off), hampering her day to day activities, was administered with the treatment protocol as per Ayurveda resulting in significant relief to her symptoms. The treatment, planned according to her pulse diagnosis and clinical examination, was based on herbal supplements, Panchakarma (detoxification) in the form of Virechana, home remedies, Marmaa therapy, dietary and lifestyle modifications. The treatment was focused on removing the toxins (Aam) from the body with the help of detox (Virechana). This also resulted in alleviation of the vitiated Vata and Pitta Doshas and restoration of the Jatharagni (digestive fire). The treatment modality has been effective to reduce the episodes significantly.

Encanto: a família e a abordagem do médico de família e comunidade / Encanto: the family and the family physician's approach / Encanto: la familia y el abordaje del médico familiar y comunitario

Encanto é uma animação de 2021 dos estúdios Disney. Retrata a história de uma família multigeracional que divide o mesmo domicílio, habitante de uma aldeia nas montanhas da Colômbia remota. A orientação familiar é atributo da Atenção Primária à Saúde e a abordagem familiar é competência do médico de família e comunidade. Esta resenha propôs-se a analisar os elementos de abordagem e terapia familiar presentes em Encanto, com base no Modelo em Quatro Etapas de Salvador Minuchin. A audiência do filme possibilita ao médico de família identificar padrões e transações familiares disfuncionais, além de elementos de terapia familiar, por isso ele pode ser útil como material de formação em abordagem familiar. Também pode ser usado como ferramenta de "cinematerapia" com as famílias que estão em acompanhamento na Atenção Primária por problemas semelhantes aos da trama.

Encanto is a 2021 animation from Disney studios. It portrays the story of a multigenerational family who share the same home, inhabitants of a village in the mountains of remote Colombia. Family centeredness is an attribute of Primary Health Care, and the family approach is the competence of the Family Physician. This review proposes to analyze the elements of approach and family therapy present in Encanto, based on Salvador Minuchin's Four-Step Model. The film's audience enables the Family Physician to identify dysfunctional family patterns and transactions, in addition to elements of family therapy, which is why it can be useful as training material in family approach. It can also be used as a "Cinematherapy" tool with families who are being monitored in Primary Care for problems similar to those in the plot.

Dyslipidemia as a risk factor for acute myocardial infarction in postmenopausal women: An observational study

Objective: This study has evaluated risk factors, especially dyslipidemia, for an acute myocardial infarction (AMI) in postmenopausal women. Materials and Methods: This was a hospital-based, observational, single-center study among 100 postmenopausal women admitted to the medicine ward with AMI. They were categorized based on lipid profile groups, viz., dyslipidemic group and non-dyslipidemic group. All clinical parameters were studied between the groups. Results: Among anthropometric profiles, in the comparison of mean height (cm), weight (kg), body mass index (BMI) (kg/m2 ), and waist circumference (WC) (cm) for the dyslipidemic group and non-dyslipidemic group, only WC was statistically significant (P < 0.001). Most patients were hospitalized between 6 and 12 h after the onset of symptoms. At the time of hospitalization, most patients from both groups were observed to have diabetes and hypertension with poor control of postprandial blood sugar, glycated hemoglobin, and diastolic blood pressure (DBP) (P < 0.05). The dyslipidemic group’s mean C-reactive protein was higher (P < 0.05). The comparison of mean total cholesterol, triglyceride (TG), low density lipoprotein-cholesterol in mg/dL, and TG: high density lipoprotein was significantly increased (P < 0.001), while high density lipoprotein-cholesterol (mg/ dL) was significantly decreased (P < 0.001) in the dyslipidemic group. ST-segment elevation myocardial infarction is standard in both groups. The maximum patient has regional wall motion abnormality in echocardiography after day 3 of admission. Among the dyslipidemic group, ejection fraction was on the lower side, and the predominant complication was in the left ventricular failure (LVF) (P < 0.05). Conclusion: WC has a positive association with patients with AMI who have dyslipidemia and can be used as an indicator of the risk of AMI when BMI is normal. WC is a surrogate marker of abdominal fat mass (subcutaneous and intra-abdominal); increased WC is a significant component marker of metabolic syndrome and insulin resistance related to cardiovascular mortality. There was poor glycemic control and blood pressure (mainly DBP) among the dyslipidemic patients. Hypertriglyceridemia is the most common lipid abnormality, followed by hypercholesterolemia among the dyslipidemic group. LVF is the most common complication in dyslipidemic patients.

Predicting respiratory motion using an Informer deep learning network / 中华放射医学与防护杂志

Objective:To investigate a time series deep learning model for respiratory motion prediction.Methods:Eighty pieces of respiratory motion data from lung cancer patients were used in this study. They were divided into a training set and a test set at a ratio of 8∶2. The Informer deep learning network was employed to predict the respiratory motions with a latency of about 600 ms. The model performance was evaluated based on normalized root mean square errors (nRMSEs) and relative root mean square errors (rRMSEs).Results:The Informer model outperformed the conventional multilayer perceptron (MLP) and long short-term memory (LSTM) models. The Informer model yielded an average nRMSE and rRMSE of 0.270 and 0.365, respectively, at a prediction time of 423 ms, and 0.380 and 0.379, respectively, at a prediction time of 615 ms.Conclusions:The Informer model performs well in the case of a longer prediction time and has potential application value for improving the effects of the real-time tracking technology.

After 1:1 propensity score matching method was used to match the patients in the 2 groups, a total of 58 pairs of patients were successfully matched. In the operative group, there were 24 males and 34 females with a mean age of (40±14) years and a body mass index of (23.7±3.4) kg/m 2; in the non-operative group, there were 22 males and 36 females with a mean age of (42±13) years and a body mass index of (23.5±3.9) kg/m 2. Elbow flexion-extension, forearm rotation, Mayo elbow performance score (MEPS), Quick-disabilities of the arm, shoulder and hand (q-DASH) score and complications were compared between the 2 groups. Results:There was no significant difference in the baseline data between the 2 groups, indicating comparability ( P>0.05). All the patients were followed up for (24±9) months. At the last follow up in the operative and the non-operative groups, respectively, the elbow flexion-extension was 134° (132°, 136°) and 134°(131°, 136°), the forearm rotation 176° (174°, 179°) and 178° (175°, 179°), the MEPS 100 (100, 100) and 100 (100, 100), the q-DASH score 0 (0, 0) and 0 (0, 0), showing no significant differences between the 2 groups in the above items ( P>0.05). Elbow pain was reported respectively in 4 (6.9%) and 6 (10.3%) patients in the operative and non-operative groups, showing no significant difference between the 2 groups ( P>0.05). Conclusion:The outcomes of operative and non-operative treatments of isolated Mason type Ⅱ radial head fracture are comparable.

Effect of three-dimensional motion platform training on balance and walking function of stroke patients / 中国康复理论与实践

ObjectiveTo explore the clinical efficacy of three-dimensional motion platform training on balance and walking function of stroke patients. MethodsFrom August, 2021 to August, 2022, 80 stroke patients from Second Affiliated Hospital of Guangzhou Medical University were selected and randomly divided into control group (n = 40) and experimental group (n = 40). The control group received routine rehabilitation training, and the experimental group received three-dimensional motion platform training on the basis of routine rehabilitation training. Before and four weeks after treatment, the Berg Balance Scale (BBS), Functional Ambulation Category (FAC) and 3D gait analysis (step speed, step frequency, percentage of standing phases on the affected side, percentage of double support phase) were used to assess the balance and walking function of patients. ResultsFour weeks after treatment, the scores of BBS, FAC, and step speed, step frequency, percentage of standing phases on the affected side and percentage of double support phase significantly improved in both groups (|t| > 4.423, |Z| > 5.292, P < 0.001), and they were better in the experimental group than in the control group (|t| > 3.748, |Z| = 2.646, P < 0.05). ConclusionThree-dimensional motion platform training could facilitate to improve the balance and walking function of stroke patients.

Cortical Mechanisms of Multisensory Linear Self-motion Perception / 神经科学通报·英文版

Accurate self-motion perception, which is critical for organisms to survive, is a process involving multiple sensory cues. The two most powerful cues are visual (optic flow) and vestibular (inertial motion). Psychophysical studies have indicated that humans and nonhuman primates integrate the two cues to improve the estimation of self-motion direction, often in a statistically Bayesian-optimal way. In the last decade, single-unit recordings in awake, behaving animals have provided valuable neurophysiological data with a high spatial and temporal resolution, giving insight into possible neural mechanisms underlying multisensory self-motion perception. Here, we review these findings, along with new evidence from the most recent studies focusing on the temporal dynamics of signals in different modalities. We show that, in light of new data, conventional thoughts about the cortical mechanisms underlying visuo-vestibular integration for linear self-motion are challenged. We propose that different temporal component signals may mediate different functions, a possibility that requires future studies.

Advances in the study of morphological changes of optic nerve and retina in horizontal eye movement / 中华实验眼科杂志

The impairment of optic disc and retinal function caused by intraocular pressure is one of the main causes of irreversible visual impairment.In addition to the effects of intraocular pressure, studies have found that ocular adduction and horizontal abduction movements affect the optic disc and surrounding retinal tissue, which result in mechanical pressure and traction having influences on tissue and this change is related to the rotation angle, speed, and age, etc.Studies have found that horizontal eye movements can cause changes in the nasal and temporal sides of the optic disc, as well as the surrounding retinal and choroidal structures, and these changes vary among different age groups.This paper reviewed the current research on the effects of horizontal eye movements on the morphology of the optic nerve and retina, in order to provide some useful clues for the treatment of relevant diseases in clinical practice.

Clinical effects of modified open elbow arthrolysis in the treatment of post-traumatic elbow stiffness / 国际外科学杂志

Objective:To study the clinical efficacy of modified open elbow arthrolysis in the treatment of traumatic elbow stiffness.Methods:A retrospective analysis was performed on 120 patients who underwent modified open elbow arthrolysis in Beijing Jishuitan Hospital from January 2018 to December 2020. The age of the included patients was (37.7±12.4) years (ranged 18-64 years), including 54 males and 66 females. The medical records were reviewed, the range of motion (ROM) and functional status of the patients before operation and at the last follow-up were compared including visual analogue scale (VAS), Mayo elbow performance score (MEPS), Disabilities of the arm, shoulder and hand (DASH) score. Complications and secondary operations were also recorded. Measurement data with normal distribution were presented as mean ± standard deviation( ± s) and comparison between groups was conducted using the t-test; Measurement data of skewed distribution were expressed as M ( Q1, Q3), and Rank-sum test was used for inter-group comparison. Results:The preoperative extension of 120 patients was 43.6° (33.8°, 60.1°), the flexion was 78.7° (59.8°, 98.1°), and the flexion-extension ROM was 25.6° (0.0°, 54.5°); the preoperative pronation was 51.8° (33.0°, 67.0°), the supination was 85.1° (65.7°, 90.0°), and the rotation ROM was 136.9° (99.1°, 157.5°). Postoperative extension was 14.2° (7.0°, 24.8°), flexion was 129.5° (120.0°, 138.1°), flexion-extension ROM was 115.5° (94.4°, 127.3°); postoperative pronation was 65.0° (47.1°, 75.0°), the supination was 88.3° (78.6°, 90.0°), and the rotation ROM was 151.9° (131.7°, 163.4°). Postoperative extension, flexion, flexion-extension ROM, pronation, supination, and rotation ROM were all higher than those before operation, and the differences were statistically significant ( P<0.001). The VAS of 120 patients was 1.0 (0.0, 3.0) scores before operation and 0.0 (0.0, 1.0) scores after operation. The MEPS was 60.0 (50.0, 75.0) scores before operation and 100.0 (85.0, 100.0) scores after operation. The preoperative DASH was 37.5 (20.1, 51.3) scores, and the postoperative DASH was 7.9 (3.3, 13.3) scores. The postoperative VAS, MEPS, and DASH were significantly improved compared with those before operation, and the differences were statistically significant ( P<0.001). Residual ulnar nerve symptoms occurred in 18 cases, recurrence of heterotopic ossification in 42 cases, and hematoma in 3 cases. Conclusions:Modified open elbow arthrolysis is a safe and effective surgical method for the treatment of traumatic elbow stiffness. It can significantly improve the function of the patient, reduce the occurrence of elbow instability, avoid the use of external fixators, and reduce the cost of the patient.
