abstract objective: to present the changes in projected thoracic hypokyphosis and the behavior of lumbar lordosis within and below the fusion and to compare these changes between the harrington rod (hr) and posterior multisegmented hook instrumentation. methods: 178 patients with idiopathic scoliosis, who had undergone posterior spinal fusion with harrington technique (106 patients) or multiseg...

abstract study design . a retrospective radiographic review was undertaken in patients treated for ais. objectives. to determine the most important preoperative factors that affect on postoperative junctional kyphosis complication. methods sagittal spine profilewere measured on the standing radiographs before, after and in the last follow-up visit of the operated patients for ais. the following...

background: increased thoracic kyphosis more than normal ranges are assessed as abnormal. but normal ranges of thoracic kyphosis in deferent age groups have not been identified in our country yet. the aim of present study was investigation of normal ranges of thoracic kyphosis to use as a diagnosis tool in school aged children in kermanshah, western-iran. methods: a descriptive research designe...

To better understand the biomechanical mechanisms underlying the association between hyperkyphosis of the thoracic spine and risk of vertebral fracture and other degenerative spinal pathology, we used a previously validated musculoskeletal model of the spine to determine how thoracic kyphosis angle and spinal posture affect vertebral compressive loading. We simulated an age-related increase in ...

 Abstract Objective: To present the changes in projected thoracic hypokyphosis and the behavior of lumbar lordosis within and below the fusion and to compare these changes between the Harrington rod (HR) and posterior multisegmented hook instrumentation. Methods: 178 patients with idiopathic scoliosis, who had undergone posterior spinal fusion with Harrington technique (106 patients) or multise...

[Purpose] The purpose of this study was to investigate the effects of thoracic extension exercise on scapular alignment and thoracic kyphosis angle. [Subjects and Methods] Ten subjects with a kyphosis angle ≥40° and aged between 20 and 26 years participated in this study. This study investigated the scapular forward distance and thoracic kyphosis angle before and after the thoracic extension ex...

Purpose Previous studies have suggested an association between increased thoracic kyphosis and neural axis abnormalities in patients with adolescent idiopathic scoliosis (AIS). However, the basis for this finding is unclear, and this association has been mainly noted in retrospective studies on a non-consecutive series of patients. The purpose of this study was to assess the relationship betwee...

STUDY DESIGN Single-cohort laboratory-based study. OBJECTIVES To measure thoracic spine extension motion during bilateral arm elevation using functional radiography and photographic image analysis. BACKGROUND Impairment of thoracic spine extension motion may impact shoulder girdle function. Motion of the thoracic spine during arm movement has not been directly measured using functional radi...

Background & Objective:  Hyper- kyphosis negatively affects health status, physical mobility, and quality of life. Corrective exercise interventions are often utilized to manage subjects with thoracic hyper-hypnosis. The purpose of this study was to investigate the effectiveness of multimodal spine strengthening exercises (spinal strengthening, spinal alignment and other such exercises for incr...
