Background: Essex-Lopresti injury (ELI) is one of the rare injuries of the elbow area, which includes fracture of radius head, disruption in the interosseous membrane of the forearm (IOM), and distal radio-ulnar joint dislocation. This happens as a result of transverse pressure on the elbow and forearm when falling down or when high energy is applied.Methods: In this study, we introduced a 40-year-old patient who suffered both bone forearm fracture in addition to the above injuries. First, the patient underwent both bone forearm ORIF surgery, and then fixation of radius head and distal radio-ulnar joint reduction and fixation.Results: After six months, the patient has 20 degrees of motion limitation only in the pronation state, and the joint’s motion range in other joints is complete.Conclusion: In general, the Essex-Lopresti injury (ELI) is one of the rare hand injuries that are difficult to diagnose with simple radiographs and requires great care.

Background: The purpose of this study was to investigate possible correlation between vitamin D in 13-36 month old children with tibial bone fracture.
Methods: This cross-sectional study was conducted on children aged 18 to 36 months who referred to a medical center in South-East of Iran with tibial fracture. All the demographic information was collected and vitamin-D levels were measured and statistically analyzed.
Results: A total of 30 children were included in the study, and the mean vitamin D level in these subjects was 31.6±6.1. This study showed no significant relationship between low vitamin D levels with increase in the risk of tibia fracture in children who had recently started walking.
Conclusion: The present study revealed a significant association between vitamin D level and its deficiency with an elevated risk of tibia bone fracture in toddlers between 18-36 months.

Background: Pulley is a synovial tissue that attaches the flexor tendons to the dorsal portions of the fibro-osseous tunnel near the tendon attachment. Pulley type A with ring structure is one of the most important pulleys in fingers. Two-stage reconstruction by silicon is the common treatment in damaged tendon which has long recovery time and the tendency of the repaired tendon to adhere to the fibrous-bone tunnel around it. Accordingly, the one-stage reconstruction by synthetic pulley is a promising approach to resolve the mentioned problems. Methods: In the present research, the polyurethane (PU) nanofiber scaffolds have been designed for synthetic pulley applications, and their mechanical and structural properties have been evaluated.Results: The structural properties of nanofiber scaffolds show similar properties to protein and polysaccharide fibers in the extracellular matrix (ECM). The Fourier transform infrared spectroscopy (FTIR) results confirmed the functional groups of PU without any unwanted reactions. The amount of stress (3.19 ± 0.54) and Young's modulus (1.20 ± 0.39) in PU nanofiber scaffolds show similar mechanical properties to natural pulley.Conclusion: The obtained results showed that the PU nanofibers scaffolds can be proposed as a suitable candidate for fabrication of synthetic pulley in flexor tendon injuries.
