Background & Aims: Thuracolumbar Unstable Fractures (T, L.U.F) are common after spine truma. Posterior pedicular fixation is a technique that is use for fixation of these fractures. This study evaluates the accuracy of pedicular screw placement in T, LUF with the assistance of plain radiography in operation rooms.   Materials & Methods: This study is a case-control and analytical study. 35 pa...

Background and Aim: Post-mortem structural changes in tissues cause technical difficulties in accurate histo-pathologic interpretation. In the present study, we evaluated the effects of microwave irradiation before tissue fixation on preventing post mortem autolysis and accelerating the process of tissue fixation in the kidneys. Materials and Methods: Twenty-four chickens randomly were divide...

Background: One of the most common orthopedic complaints is direct or indirect trauma to the knee with torn anterior cruciate ligament (ACL). Reconstruction of the torn ACL is emphatically offered in active individuals as by this operation, we prevent osteoarthritis, knee instability and injury to the meniscus. There are numerous methods for graft fixation in the femoral tunnel in ACL reconstru...

Potassium (K) fixation in soil is an important process which affects the availability of K to plants. There is limited information on K fixation capacity (PFC) of soils in Chahar Mahal & Bakhtiary province. This study was carried out with the aim of determining PFC and its relation with soil characteristics in 10 samples of surface soils in Chahar Mahal & Bakhtiary province. PFC was determined ...

Background: Open reduction and internal fixation is the standard surgical approach for lisfranc fracture, however, osteoarthritis is a long term complication.
