Modern human society is continuously becoming more and more complex and interconnected, thanks to advanced sources of communication, social mobility, and international relations. A considerable amount of science and data is one of the products of this complex human system, which stresses the quality of information transfer and education for all, and also derives socio-cultural evolution. Scientific societies are one of the crucial parts of socio-cultural evolution by their creative role (1). Scientists' role, as the members of the professional society, is becoming more sub-specialized and, at the same time, more relied on other sub-specialized members of the system, to keep the system running together...

Background: Meniscus plays a pivotal role in normal function of knee joint and is exposed to heavy load of pressure and trauma. The aim in this study is to investigate ultrastructure of medial and lateral meniscus of Ovis aries, in addition to comparing the findings with human meniscal structure. Methods: 14 samples of freshly-excised meniscus of ovis aries were provided. After conventional preparation, the samples were studied via electron microscopy (EM) and its elements were microanalyzed. Results: In the macroscopic evaluation, the meniscus surface was completely smooth, but in the microscopic observation, longitudinal ridges and grooves were observed. In addition, several types of cells that were different morphologically and bundles of collagen fibers were observed. The major direction of collagen fibers was circumferentially, but there were radial fibers as well. In the microanalysis of the ovis aris meniscus, the following elements were present: sodium, carbon, and oxygen, with sodium having the highest percentage among the elements. In medial meniscus of the samples, a small amount of calcium was detected. Conclusion: By comparing the present findings with those of other studies, many similarities were observed between ultrastructure of ovis aries and human knee meniscus. The compatibility in the ultrastructures will imply the possibility of application of this specimen for xenograft meniscal transplant procedure.

Background: Carpal tunnel syndrome (CTS) is the most common compression neuropathy in the upper limb which needs surgery in many cases. Two common surgical incisions for carpal tunnel release (CTR) are classical incision and minimal incision. In this survey, the aim is to compare patient-reported outcomes of these two types of incisions. Methods: In this retrospective study, patients with CTS who underwent two different approaches for CTR (classical or minimal) during one year were included. The diagnosis was confirmed clinically and by electrodiagnostic studies. The patients were categorized into two groups regarding the type of surgery. At the 12-month visit, the patients were assessed for functional outcome, level of the pain, and satisfaction with Quick Disability of Arm, Hand and Shoulder score (QuickDASH), the visual analogue score (VAS) scale, and the scar appearance and symptom relief, respectively. Results: 39 patients were entered in this study, 3 of who had bilateral symptoms. The 42 operated hands were divided into two groups: classical incision group (n = 21) and minimal incision group (n = 21). No significant difference was discovered between the two groups considering age and sex. In addition, no significant difference was found in the variables evaluated between the two groups, except for the higher patient satisfaction with the scar appearance in minimal incision group after 12 months. Conclusion: After a one-year period, the minimal incision procedure had no priority to classical incision procedure, except for higher patient satisfaction considering the scar appearance.

When a happy six-year-old boy comes to your clinic with complaints of pain in his right hip after activity and his parents say their son has limping, which important disease should not be missed? The answer is the Legg-Calvé-Perthes disease (LCPD). This pediatric orthopaedic condition corresponds to an avascular necrosis of the proximal capital femoral epiphysis (1). Arthur T. Legg, Jacques Calvé , and Georg Perthes were the first to describe the disease in 1910 (2) and after 110 years, causes of the disease are still unclear...

This study addresses the approach to the failure of a femoral neck fracture fixation construct and is performed with the aim to discuss the causes and treatment options of the failure of a femoral neck fixation construct in a stepwise approach (Figure 1)...

Proximal humerus fracture-dislocation is a rare condition that occurs mostly in young adults due to high energy trauma and about 60-79 percent of misdiagnosis is occurred in the first diagnosis. In this article, we present two patients with proximal humerus fracture-posterior dislocation the fractures of whom were diagnosed, but after the radiographic studies including x-ray and computer tomography (CT) scan, the posterior dislocation was misdiagnosed. In addition, complications, management, and avoidance of this misdiagnosis were discussed.

Background: Laryngeal fractures are one of the complications of direct damage to the neck, which can lead to airway obstruction and life-threatening conditions. Other causes of laryngeal fractures include injuries during fights, sports injuries, hangings, and iatrogenic causes. In this study, we introduce a child with a laryngeal fracture following an accidental hanging. Case Report: A 9-year-old girl was presented to the emergency department with respiratory distress and inability to speak after being hanged by her scarf. We secured the cervical spine with a hard collar and provided two intravenous (IV) lines. Then, the patient was transferred to the radiology department to perform cervical and thoracic computerized tomography (CT) scans. In the cervical CT scan, the fracture of laryngeal cartilage was detected. We repaired the fracture by prolene sutures. Then the patient was transferred to the intensive care unit (ICU) ward. After 2 days, she was transferred to ward and discharged without any complications. Conclusion: The cervical trauma is a critical condition that must be managed carefully and urgently. For the rapid diagnosis of possible damage, imaging is necessary. Among all modalities, CT scan is the best choice for detection of the vertebral injuries and airway competence in emergent conditions.
