OBJECTIVE Trauma-associated cartilage fractures occur in children and adolescents with clinically significant incidence. Several studies investigated biomechanical injury by compressive forces but the injury-related stress has not been investigated extensively. In this study, we hypothesized that the biomechanical stress occurring during compressive injury predetermines the biomechanical, bioch...

Spinal compression is traditionally assumed the principal biomechanical mechanism associated with occupationally related low-back disorders (LBD). However, there is little conclusive evidence demonstrating that compression is related to occupational LBD. The objective of this research was to examine whether axial compression in the lumbar spine can predict the probability that a lifting task sh...

Degenerative instability is difficult to define, diagnose, and treat. Diagnosis and treatment of degenerative instability are based on the biomechanical stability of the functional spinal unit as well as on the pathologic diagnosis of the disease. Recent advancements in biomechanical studies on the functional spinal unit and radiological diagnostic methods have introduced new diagnostic criteri...

Hydrological response of a watershed is a comprehensive symbol of environmental conditions and characteristics of the basin. Vegetation is one of the main factors in water resources status, erosion, and sediment of a watershed. Rangelands of Golestan province, Iran due to the geographical location, climate, and destruction of these resources as well as drastic land use changes from forests, and...

Tendon never restores the complete biological and mechanical properties after healing. Several techniques are available for tissue-engineered biological augmentation for tendon healing like stem cells. Recently, synovium has been investigated as a source of cells for tissue engineering. In the present study, we investigated potentials of fibroblast like synoviocytes (FLSs) in tendon healing. Si...

background: ligament reconstruction is a common procedure in orthopedic surgery. although several popular techniques are currently in use, new methods are proposed for secure fixation of the tendon graft into the bone tunnel. purposes: we sought to introduce our new technique of bashti bone plug for fixation of soft tissue graft in anterior cruciate ligament (acl) reconstruction and to compare ...

Considerable achievements having been recently made in modern diagnostics and treatment of keratoconus have not diminished the urgency of the given problem as the traditional views of the pathogenesis of keratoconus do not always allow to struggle effectively with this difficult and continuously progressing disease. The objective of the research was to study the peculiarities of biomechanical p...
