Introduction: this study was aimed at assessing the effect of a new THORACOLUMBAR orthosis on patients with Scheuermann's kyphosis referred to Iran medical university of Tehran in collaboration with a clinic of technical ortopedea in Isfahan.Material and method: This new version of orthosis had a DYNAMIC system as compared to previous ones which enabled the spine to extend. a questionnaire along with a radiographic picture of spine were used for evaluating the efficacy of this kind of orthosis. Measurement of the Cobb angles was also performed in 3 stages.Results: mean difference correction of Cobb angle for DYNAMIC THORACOLUMBAR orthosis was 29.5% and mean difference correction of Cobb angle for Milwaukee was 35.5%. Difference of Cobb angle was measured by Cobb angle before application orthosis and by second month of its usage.Conclusion: results showed that not only was the new DYNAMIC THORACOLUMBAR orthosis effective in orthosis correction and improved Cobb angle at 2 months follow-up but also it was well accepted by the user thanks to its beautiful structure.

The aim of the present study was to design a new corrective and wireless THORACOLUMBAR bracing for individuals with functional THORACOLUMBAR kyphosis. For designing a new corrective and wireless THORACOLUMBAR bracing, we used elastic thoraco-lumbo-sacral support. The support structure of the present brace formed by six straps to adjust, two metals to hold, support structure in electronic form, and two local stabilizers with bending sensor. The software of this brace designed to be able to find out the bending angle of the bending sensor. Electronic system connects through mobile App using Bluetooth connection. To do this, the researcher must turn on the electronic circuit, then device and mobile phone connects with Bluetooth. After that, the bending sensor data transform to the mobile software and the software shows the amount of bending on the mobile phone. The new corrective and wireless THORACOLUMBAR brace designed in the present study could be used in the corrective training programs and also during daily activities. The alarm system of this brace made it a suitable and user-friendly brace for corrective aims of kyphosis malalignment. In patients with the all grade of abnormal kyphosis or lordosis, we mount the wireless THORACOLUMBAR brace strapped to the hip and chest. Bending sensors send information of the kyphosis or lordosis angle in sagittal plane to the microcontroller. When angle is greater than the normal angle, microcontroller switch on the vibration switch to alarm patient to correct his/her posture. The current wireless device deemed to use in the corrective training programs and also during daily activities in patients with some postural abnormalities.

Due to the lack of measurements in many regions, wave characteristics are estimated using different methods. Wave climate hindcasting/forecasting is mostly conducted by numerical models or empirical methods. Until now, different empirical methods have been developed for wave hindcasting. However, with the development of high speed processors, several sophisticated numerical models have been developed for wave prediction. These models are mostly phase-averaged spectral wave models developed in three generations. In the last two decades, third generation wave models have been used widely in academic and practical projects. In this regard, Port and Maritime Organization has produced his own model, PMO DYNAMIC. This model has been developed as a part of first three phases of Monitoring and Modeling of Study of Iranian Coasts project. PMO DYNAMIC package is a software available for engineering purposes. It has several modules that have been developed for different objectives. Wave model is the module which is used for the generation and transformation of wind waves in coastal areas. In this paper, in order to test the PMO DYNAMIC model capabilities, it has been applied for the prediction of wave parameters in Bushehr Bay and the results have been compared with MIKE21 SW model and measured data.

Background: In intertrochanteric fractures، DYNAMIC hip screw (DHS) is the most frequently used tool، but several studies did not give good results for this device in reverse-oblique and transverse fractures. Current study aimed to compare fixation results of reverse-oblique intertrochanteric and short-segment subtrochanteric fractures using DYNAMIC condylar screw (DCS) and DHS in patients referred to Alzahra and Kashani Hospitals in Isfahan, Iran.Methods: In a cross-sectional study، medical files of the patients referred to emergency units of the two hospitals who were diagnosed with intertrochanteric or subtrochanteric fractures and underwent DHS or DCS surgery more than 6 months before were assessed; they were invited for follow-up visit and examination. Written consent forms were taken from all the patients upon their entry; and they were examined in terms of complications including nonunion and failure of device and level of fracture improvement. These cases were evaluated by simple radiography ,too. Results obtained from examination of patients in addition to demographic information were recorded in the data collection form for each patient.Findings: Perfect union was observed in 14 (of 25) patients in DHS group and 21 (of 25) patients in DCS group (56% vs. 84%) six months after the surgery. Bone union was significantly better in DCS group (P=0.031). In addition, six months after the surgery, the devices used in 14 people in DHS group and 24 people in DCS group were fixed and the difference between the two groups was significant (P=0.001). 14 and 24 patients had total recovery in DHS and DCS groups، respectively (20% vs. 44%) with a significant difference (P=0.020).Conclusion: Considering obtained results, it can be concluded that using DCS is recommended over DHS due to severity of pain, bone union and fixation of the device.

Chordomas are rare tumors from primitive notochord. They are usually located at sacrococcygeal region when it affects the spine. We present a case of giant chordoma in the THORACOLUMBAR spine in Peru. A 43-year-old woman came to the hospital in Huanuco due to back pain and sensorymotor alterations in the lower limbs. Imaging confirmed an unresectable tumor involving the spine. Two years later, she came back with paraplegia, weight loss, severe anemia and complicated urinary tract infection. Magnetic resonance imaging confirmed a mass measuring 15×15×14 cm in T11, T12 and L1 which histopathology was consistent with chordoma. Chordoma is a rare tumor which should be included in the differential diagnosis of spinal tumors. An earlier diagnosis leads to more options of treatments and longer survival.
