This study has shown high prevalence of LBP among future healthcare provider. These risk factors should be well established to minimize the prevalence of LBP among future health sciences students. Dentistry students at higher risk of developing LBP compared to other students.

BACKGROUND: The accessory navicular bone (ANB) is one of the most common accessory bones in the foot. Certain pathologies, such as posterior tibial tendon insufficiency are associated with ANB, and should be differentiated from midfoot and hindfoot fractures such as navicular tuberosity avulsion fractures. There are few studies addressing the prevalence and types of ANB in Saudi Arabia. OBJECTIVES: Determine the prevalence and morphological variations of ANB and its relation with age and sex in patients visiting foot and ankle clinics. DESIGN: Medical record review SETTING: Orthopedic foot and ankle clinic at a university hospital. PATIENTS AND METHODS: The presence of ANB was retrospectively analyzed in radiographs from patients who presented to the orthopedic foot and ankle at our university hospital from February 2010 to December 2020. The patients were stratified according to sex, age, and diagnosis. For each ANB, recorded information included site, size, classification, subtypes, and symptomatology. Purposive sampling was used to select the patients for the study (non-probability sampling). MAIN OUTCOME MEASURES: Prevalence of ANB in patients attending a foot and ankle clinic. SAMPLE SIZE: 117 patients and 194 feet. RESULTS: ANB was analyzed in 1006 radiographs from 503 patients. ANB was detected in 117 (23.3%) patients and 194 (19.3%) feet Prevalence was significantly higher in females (67.5%) than in males (32.5%) (Z=5.359, P <.001). The ages ranged from 19 to 86 years, with a mean age of 48.26 (14.5) years. The most common site was bilateral (77 patients, 65.8 %). Type I was the most common type, with a prevalence of 42.1%. There were no significant differences in types in relation to sex, but all types and subtypes differed significantly from each other. CONCLUSION: ANB was common among patients presenting to the foot and ankle clinic, with an overall prevalence of 23.3%. It should be considered among the differential diagnosis in chronic foot pain, and should be differentiated from midfoot and hindfoot fractures. Further studies with a larger, randomized sample are needed, for more accuracy and to confirm the reported results. LIMITATIONS: Retrospective chart review, non-probability sampling, and use of plain radiographs. CONFLICT OF INTEREST: None.

Introduction: The purpose of this study is to identify the knowledge of the general population about knee osteoarthritis and its surgical interventions in the management of knee osteoarthritis. Knee osteoarthritis is a prevalent disease. A lack of knowledge about the nature of the disease may delay seeking medical advice until the advanced stage of the disease. Methods: This cross-sectional study was conducted among 486 participants (≥18 years) who were sampled randomly from an osteoarthritis awareness campaign located within a shopping facility located in Riyadh in 2020. Data were collected via a structured questionnaire, which included six domains; demographic information, causes, symptoms, treatment, complications, and general questions. Data for this study were analyzed by using the Statistical Package for Social Studies (SPSS 22; IBM Corp., New York, NY, USA). Continuous variables were expressed as mean ± standard deviation and categorical variables were expressed as percentages. The t-test and one-way Analysis of Variance (ANOVA) were used for continuous variables. Univariate and multivariate logistic regression were used to assess the associated factors with a low level of knowledge. A P value of <0.05 was considered statistically significant. Results: Most of the participants in our study were males (56.8%) and Saudi nationals (89.7%). (83.74%). Consider that surgical intervention is the best treatment when non-surgical options do not work. The mean questionnaire score for the 486 participants was found to be 20.85 ± 5.29 out of 35 points. In comparing the male to female total scores, we found the mean female total score to be statistically significant and higher than that of the males with a P value of 0.036. Furthermore, we found that the non-Saudis had a total score higher than the Saudis with a P value of 0.016. On the other hand, the difference in the total scores between the city and rural area residents and different educational levels were statistically insignificant. Conclusions: Our results demonstrate that the majority of the community has satisfactory awareness about the treatment options of knee osteoarthritis. It also demonstrates the domains that require more effort for increased public awareness of knee osteoarthritis.

Patient: Male, 4-week-old Final Diagnosis: Arthrogryposis Symptoms: Limited hip motion Medication:— Clinical Procedure: Open reduction of hip and femoral shortening Specialty: Orthopedics and Traumatology Objective: Unusual or unexpected effect of treatment Background: Arthrogryposis is a congenital condition of multiple contractures of joints associated with hip dislocation. The outcome of open reduction of hip dislocation in arthrogryposis patients is debatable. Open reduction of arthrogryposis is challenging for shallow acetabulum and extensive adhesions and fibrosis. For this reason, a careful extensive release must be carried out to achieve the open reduction of the hip in arthrogryposis patients. The literature lacks surgical recommendations for open reduction of the hip in arthrogryposis patients and how to deal with cases of the extruded bone segment during open reduction. Case Report: The patient presented in the first few weeks of life with bilateral clubfoot and left hip dislocation. Clinical diagnosis of arthrogryposis was made after referral to a genetics specialist. The hip was clinically irreducible. The patient underwent open reduction and femoral shortening using the Smith Peterson approach at the age of 15 months, with accidental extrusion of the proximal femur, which was retained immediately. The clinical outcome showed a painless, good range of motion. Radiographically, features of avascular necrosis and healed osteotomy site were evident. Conclusions: A difficult hip reduction was expected in this arthrogryposis patient, which required careful dissection of surrounding fibrosis and appropriate femoral shortening. Careful dissection should be carried out during open reduction to avoid jeopardization of femoral head vascularity or even complete devitalization of the proximal femur.
