Study Design: To induce scoliosis in young female Wistar rats using a noninvasive method and to validate this model. Purpose: To induce scoliosis in a rat model noninvasively by bracing and to study the corresponding gene-expression profile in the spine and different organs. Overview of Literature: Scoliosis involves abnormal lateral curvature of the spine, the causes of which remain unclear. In the literature, it is suggested that scoliosis is genetically heterogeneous, as there are multiple factors involved directly or indirectly in its pathogenesis...

Study Design: Cross-sectional analytical study. Purpose: To evaluate the spinal radiological features in patients with Scheuermann's disease and the association between the thoracic kyphosis angle and clinical presentation. Overview of the Literature: Scheuermann's disease is the most common cause of hyperkyphosis of the thoracic and thoracolumbar spine in adolescents; however, literature is limited in this area. Methods: Data regarding 150 successive X-ray images of 95 males and 55 females diagnosed with Scheuermann's disease were retrieved from the digital archives of the Maccabi Healthcare Services in Tel Aviv...

Study Design: A prospective, within-group cohort study of 46 patients with chronic low-back pain (CLBP). Purpose: To assess the responsiveness of the Persian Functional Rating Index (PFRI) and to determine the minimal clinically important change (MCIC) of the PFRI in a cohort of patients with CLBP. Overview of Literature: The FRI is an instrument for assessing pain and disability in patients with low-back pain. No study so far has examined the responsiveness of the PFRI...

Cervical kyphosis is a rare condition that can cause significant functional disability and myelopathy. Deciding the appropriate treatment for such deformities is challenging for the surgeon. Patients often present with axial neck pain, and it is not uncommon to find coexisting radiculopathy or myelopathy. The optimal approach for addressing this complex issue remains controversial. A comprehensive surgical plan based on knowledge of the pathology and biomechanics is important for kyphosis correction. Here we reviewed diagnoses of the cervical spine along with the literature pertaining to various approaches and management of cervical spine...
