Clinical symptoms and imaging findings of cervical instability in young adult / 中国骨伤

OBJECTIVE@#To explore clinical symptoms and X-ray imaging features of cervical instability in young adult represented by postgraduates with a master's degree in medicine.@*METHODS@#Totally 91 postgraduates with a master's degree in medicine were investigated from September to December 2021, including 45 males and 46 females;aged from 22 to 30 years old with an average of (25.30±2.18) years old. The cervical spondylosis-related discomfort symptoms of the subjects were collected and examined by the examiner for neck and shoulder tenderness point examination and cervical vertebra positive and lateral and functional X-ray radiography. According to the results of X-ray examination, the subjects were divided into stable cervical group and unstable cervical group.@*RESULTS@#Among 91 subjects, there were 50 patients with cervical instability, accounting for 54.90% of total number of subjects. The cervical curvature was abnormal in 78 patients, accounting for 85.70% of total number of subjects. Among 50 patients with cervical instability, 50 patients were diagnosed as cervical instability on the basis of angular displaxement(AD)≥ 11 °, including 13 cases of C3,4 instability, 30 cases of C4,5 instability and 7 cases of C5,6 instability;and 5 cases were diagnosed as cervical instability based on horizontal displacement(HD)≥ 3.5 mm, including 1 case of C3,4 instability and 4 cases of C4,5 instability. Compared with stable cervical group, the number of discomfort symptoms of neck pain, headache and shoulder pain in instability group was significantly higher than that of in stable cervical group(P<0.05);and the number of tenderness in spinous process space of C4,5 and C5,6, 2 cm adjacent to the spinous process of C2-C5 and the superior angle of the scapula (the stop point of levator scapulae) in the instability group was significantly higher than that in the stable cervical group (P<0.05);and the cervical curvature in the instability group was significantly lower than that in stable cervical group(P<0.05).@*CONCLUSION@#The incidence of cervical instability in young adult represented by postgraduates with a master's degree in medicine is high, they are mainly diagnosed as cervical instability on the basis of vertebral angular displacement ≥ 11°, and the instability segments are concentrated on C3,4, C4,5 and C5,6 segments, the occurrence of cervical instability is often accompanied by abnormalities of cervical curvature. Most of clinical manifestations are head, neck and shoulder pain, especially neck pain in unstable segment.

Research on the improved image tracking algorithm of athletes' cervical health / Pesquisa sobre o algoritmo de rastreamento de imagem aprimorado da saúde do colo do útero de atletas / Investigación sobre el algoritmo de seguimiento de imágenes mejorado de la salud cervical de los atletas

ABSTRACT Objective: With the increasing number and youth of patients with cervical spondylosis, people pay more and more attention to the cervical spine. Early diagnosis, intervention and treatment play an important role in the recovery of cervical spondylosis. With the continuous development of computer technology, the improvement of various modeling theories, and the application of image processing methods in orthopedics, new ideas are opened to observe cervical vertebra motion health. Methods: In this paper, the measurement of cervical motion is achieved by machine vision. A method of parameter measurement based on the constraint relationship of lower cervical motion is proposed. Based on image preprocessing, the left edge of the cervical vertebra was extracted and analyzed. Results: With the horizontal coordinate of registration point as the reference line, the changing trend of the angle between the left edge curve and the reference line of C4 and C5 vertebrae in the process of spontaneous flexion and extension of the cervical vertebrae was observed, and the movement rate of the cervical vertebrae was analyzed. Conclusions: It was found that the speed of the cervical vertebrae in the process of movement of the patients with cervical spondylosis showed jumping changes. Level of evidence II; Therapeutic studies - investigation of treatment results.

RESUMO Objetivo: Com o aumento do número e da juventude dos pacientes com espondilose cervical, as pessoas prestam cada vez mais atenção à coluna cervical. O diagnóstico, intervenção e tratamento precoces desempenham um papel importante na recuperação da espondilose cervical. Com o desenvolvimento contínuo da tecnologia computacional, o aprimoramento de várias teorias de modelagem e a aplicação de métodos de processamento de imagens na ortopedia, novas ideias se abrem para observar a saúde do movimento das vértebras cervicais. Métodos: Neste trabalho, a mensuração do movimento cervical é realizada por meio de visão artificial. É proposto um método de medição de parâmetro baseado na taxa de restrição de movimento cervical inferior. Com base no pré-processamento da imagem, a borda esquerda da vértebra cervical foi extraída e analisada. Resultados: Com a coordenada horizontal do ponto de registro como linha de referência, a tendência de mudança do ângulo entre a curva da borda esquerda e a linha de referência das vértebras C4 e C5 foi observada no processo de flexão espontânea e extensão do vértebras, vértebras cervicais e a taxa de movimento das vértebras cervicais. Conclusões: Verificou-se que a velocidade das vértebras cervicais no processo de movimentação de pacientes com espondilose cervical apresentou alterações de salto. Nível de evidência II; Estudos terapêuticos- investigação dos resultados do tratamento.

Sinal de Faget como manifestação clínica de brucelose. Relato de caso / Faget's sign as a clinical manifestation of brucellosis: Case report

Relata-se o caso de uma paciente do sexo feminino, 32 anos, comerciante, com manifestações sistêmicas de brucelose, como febre diária contínua, sinal de Faget, lombalgia, cervicalgia, náuseas e cefaleia. Quando questionada, a paciente referiu consumo de leite e queijo não pasteurizados de origem bovina. Nos exames laboratoriais, foram evidenciados leucocitose, linfopenia, proteína C-reativa dentro dos parâmetros da normalidade e ausência de transaminasemia, contrapondo achados clássicos da doença. Os exames de imagem mostraram sinais característicos de sacroileíte. O tratamento foi realizado com doxiciclina 100mg via oral a cada 12 horas e estreptomicina 1g via intramuscular diária. O resultado da titulação para brucelose foi positivo. A paciente teve boa resposta ao tratamento, mantendo-se afebril e em bom estado geral até a alta hospitalar, que ocorreu após 14 dias do início da medicação, tendo sido mantido o tratamento ambulatorialmente.

Radiographic lumbar spondylosis: Gender and age group prevalence in Nigeria

Background: Lumbar spondylosis (LS) increases with, and is perhaps an inevitable concomitant of age, and is a major cause of low back pain and disability in the elderly. The prevalence in Nigeria is poorly documented, and its knowledge will assist in patient management. Objective: The aim is to study the gender and age group prevalence of LS in Nigeria. Materials and Methods: This is a retrospective review of 368 anteroposterior and lateral lumbosacral spine spondylotic radiographs of patients of both genders. Data analysis was performed with IBM SPSS Statistics 20.0 (New York, USA). The value of P < 0.05 was considered statistically significant. Results: The age range was 17­90 years, mean (standard deviation) was 51.96 (13.49) years. The majority (201 [55%]) were aged 45­64 years. The males (217 [59%]) were aged 17­90 years, and the mean (standard deviation) was 52.28 (14.49) years, whereas the females (151 [41%]) were aged 17­80 years, and the mean (standard deviation) was 51.51 (11.95) years. The mean ages showed no significant gender difference (P = 0.429). Male: female ratio was 1.4:1. LS prevalence increased with age, peaked at 45­54 years in females, 55­64 years in males, and steadily declined to zero, in females after 80 years, and in males after 90 years. Conclusion: LS prevalence started as early as 17 years of life, increased with age, peaked at 45­54 years in females, 55­64 years in males, and steadily declined to zero, in females after 80 years, and in males after 90 years. Sex ratio showed slight male preponderance
