In this study, we present the case of a 42-year-old man with a fracture and dislocation of the left talus neck, and a fracture of the right talus neck due to a fall. This kind of fracture can be considered rare, and thus few cases have been reported. Fracture fixation was provided through cannulated screws on either side. Splints were removed after 6 weeks, and passive/active joint movement exercises were started. The patient was able to walk with partial weightbearing at 2 months and with full weightbearing at 3 months...

In scaphoid fractures, delayed diagnosis and nonunion are fairly common as a result of several factors, including the difficulty of radiographic diagnosis of non-displaced fractures and underestimation of the injury by the patient. Main factors to consider when deciding treatment are the type of fracture and fracture stability. In the stable nonunion (Type D1 according to the Filan and Herbert classification, or linear type of Ikeda's classification), percutaneous screw fixation without bone graft is recommended...

Osteoarthritis and articular cartilage injuries are common conditions in human joints and a frequent cause of pain and disability. Unfortunately, cartilage is avascular and has limited capabilities for self-repair. Despite the societal impact, there is little information on the dynamic process of cartilage degeneration. We performed a series of cyclic unconfined compression tests motivated by in vivo loading conditions and designed to generate mechanical fatigue. We examined the functional (both stress-stretch and creep) responses of the tissue after recovery from a specified number of loading cycles, as well as histology and second harmonic generation microscopy images...

OBJECTIVE: To report a familial case of Familial Exudative Vitreoretinopathy (FEVR) with an autosomal dominant inheritance pattern identified with the molecular analysis of FZD4. CASE REPORT: The proband is a 13 year-old boy who consulted for low vision. Fundus examination revealed a peripheral avascular zone and macular dragging, consistent with FEVR. Molecular analysis demonstrated a mutation of FZD4 in DNA from both the patient and his asymptomatic mother. DISCUSSION: This familial case was identified with the molecular analysis of FZD4 and shows the importance to explore first degree relatives in a sporadic FEVR case...

Traumatic hip dislocation is uncommon in children. Yet, it represents an orthopaedic emergency, because delayed treatment can lead to avascular necrosis of the femoral head. In this case a four-year-old boy and an eight-year-old girl were treated in an emergency department less than two weeks apart. They both received a posterior hip dislocation after accident during sledging. Their hips were reduced within six hours in the operating theatre, and the patients were discharged few days later. At the follow-up after six and 12 weeks both patients were doing well, and X-rays were normal...

The multifunctional growth factor CYR61/CTGF/NOV (CCN) 2, also known as connective tissue growth factor, regulates cellular proliferation, differentiation, and tissue regeneration. Recent literatures have described important roles of CCN2 in the meniscus metabolism. However, the mechanical stress-mediated transcriptional regulation of CCN2 in the meniscus remains unclear. The meniscus is a fibrocartilaginous tissue that controls complex biomechanics of the knee joint. Therefore, the injured unstable meniscus has a poor healing potential especially in the avascular inner region...

Down syndrome candidate region 1 (DSCR1) has two differentially regulated isoforms (DSCR1-1 and DSCR1-4) and is reported to play a role in a number of physiological processes, such as the inhibition of cardiac hypertrophy, attenuation of angiogenesis and carcinogenesis, and protection against neuronal death. However, the function of DSCR1 in the retina is still not clear. Therefore, we analyzed the expression and location of DSCR1 in the retina of neonatal mice with oxygen-induced retinopathy (OIR), and studied its effects on angiogenesis...

BACKGROUND: It has been reported that formononetin (FMN), one of the main ingredients from famous traditional Chinese medicine "Huang-qi" (Astragalus membranaceus [Fisch] Bunge) for Qi-tonifying, exhibits the effects of immunomodulation and tumor growth inhibition via antiangiogenesis. Furthermore, A. membranaceus may alleviate the retinal neovascularization (NV) of diabetic retinopathy. However, the information of FMN on retinal NV is limited so far. In the present study, we investigated the effects of FMN on the hypoxia-induced retinal NV and the possible related mechanisms...

Osteoarthritis of the hip remains a prevalent disease condition that influences ever-changing treatment options. Procedures performed to correct anatomic variations, and, in turn, prevent or slow the progression of osteoarthritis, are aptly referred to as types of hip preservation surgery (HPS). Conditions that predispose individuals to femoroacetabular impingement (FAI), including pincer- and cam-type morphology, and hip dysplasia are specifically targeted in HPS. Common surgical interventions include acetabuloplasty, osteochondroplasty, periacetabular osteotomy (PAO), and derotational femoral osteotomy (DFO)...
