The primary objective was to assess the diagnostic accuracy of a deep learning-based artificial intelligence model for the detection of acute appendicular fractures in pediatric patients presenting with a recent history of trauma to the emergency department. The secondary goal was to examine the effect of assistive support on the emergency doctor’s ability to detect fractures.

Introduction: Osteoid osteomas are benign osteoblastic bone tumors mostly seen in patients in the second or third decade of life, and they most frequently involve the femur and tibia. Hallux osteoid osteoma is an extremely rare occurrence with only 14 reported cases to date. Presentation of case: A 46-year-old woman with a right hallux pain for the last 18 months was admitted. Her foot radiographs showed a small sclerotic focus on the distal phalanx and degenerative changes in the interphalangeal joint of the hallux. The complaints of the patient were attributed to osteoarthritis involving the interphalangeal joint and non-steroidal anti-inflammatory drugs were administered; however, the patient’s condition did not improve, and hallux osteoid osteoma could not be correctly diagnosed until a CT scan was performed. Discussion: We present a case of hallux osteoid osteoma in which the diagnosis was delayed greatly due to the unusuality of the lesion location, the advanced age of the patient, and the uncertainty of the clinical and radiographic appearance. Conclusion: Although rare, osteoid osteoma may occur in the hallux. Even if the patient age, pain pattern, and radiographic findings do not exactly meet the classical definitions for osteoid osteoma, this tumor should always be included in the differential diagnosis list in patients presenting with foot pain.

Chronic nonbacterial osteomyelitis (CNO) is a rare autoinflammatory disease affecting the bone in which, diagnostic delays are common due to lack of physician awareness. The aim of this study was to evaluate the knowledge of orthopedic surgeons and pediatricians about CNO and to investigate the effect of professional experience on this process. This study was conducted between January-February 2025 using a 13-item online questionnaire comprising multiple-choice questions with clearly defined correct and incorrect answers. The questionnaire consisted of two main categories. The first category included questions regarding the clinicians' areas of specialization, professional experience, and training needs. The second category aimed to assess clinicians' knowledge levels about CNO. For each participant, the number and rate of correct and incorrect responses were calculated. The questionnaire was sent to a total of 551 clinicians and 244 of them (44.2%) (130 orthopedic surgeons, 114 pediatricians) completed the questionnaire. Of the 61 items, orthopedic surgeons had a median of 30 correct responses (26-35), while pediatricians had a median of 32 (28-36) (p = 0.023). The rate of giving the correct answers to the questions increased with the professional experience of the clinicians (p = 0.02). 116 (47.5%) clinicians stated that they didn't think to have sufficient knowledge about CNO and 212 (86.8%) clinicians stated that they'd like to participate in a training about CNO. This study demonstrates that both orthopedic surgeons and pediatricians still have significant knowledge gaps regarding CNO. Although the current level of awareness remains limited in both groups, they appear willing to acquire further knowledge. These findings highlight the need for focused educational programs to improve patient care.

Aim: To investigate the epidemiological characteristics of patients with pelvic fractures. Material and Methods: We evaluated age, gender, comorbid disease, admission season, mechanisms of the injury, type of the fractures (Young Burgess classification), associated injuries, and mortality of patients with pelvic fractures in the emergency department (ED). Results: Of the 919 patients included in the study, 307 (33.4%) were female and 612 (66.6%) were male. The mean age was 36,5±14,82 (18-80) years. The mean age of males was 35.1 ± 13.63 years, and it was 39.2 ± 16.63 years for females. Of the males, 46.4% were in the 28-37 years range. Comorbid diseases were found in 254 (27.6%) patients. Of the patients, 302 (32.9%) were admitted in winter and 285 (31%) in summer. It was mostly occurred due to automobile accidents 268 (29.2%), followed by falls from height 211 (23%). Automobile accidents were most common in the winter season, while falls from height was more common in the summer. While automobile accidents, falls from height, motorcycle accidents were more common in males compared to females, falls from own height, pedestrians hit by a car, and other injuries were observed more frequently in females than males (p
