BACKGROUND Kyphosis is a cause of scapular dyskinesis, which can induce various shoulder disorders, including subacromial impingement syndrome (SIS). This study aimed to clarify the impact of kyphosis on SIS with use of cross-sectional data from the Locomotive Syndrome and Health Outcome in Aizu Cohort Study (LOHAS). METHODS The study enrolled 2144 participants who were older than 40 years an...

Kyphosis is an idiopathic disease characterized by abnormal, outward spinal curvature. A spontaneous outbreak and subsidence of kyphosis over a 4-mo period in the University of Wisconsin Swine Research and Teaching Center herd coincided with an accidental omission of vitamin D(3) in 1 of 2 premixes used in sow diets. This controlled experiment was conducted to determine whether vitamin D deleti...

We analysed the cases of lumbar kyphosis in 151 (21%) of a series of 719 patients with myelomeningocele. Three different types were distinguished: paralytic, sharp-angled and congenital. In a cross-sectional and partly longitudinal study the size and magnitude of the kyphosis, the apex of the curve and the level of paralysis of each group were recorded and statistically analysed. Paralytic kyph...

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...

OBJECTIVE The purpose of this study was to determine the prevalence of kyphosis in a Turner syndrome (TS) population. METHODS Standing lateral thoracic spine and standing anterior-posterior (A-P) scoliosis radiographs were obtained on all girls with TS between the ages of 5 and 18 years seen in a TS clinic between July 2000 and March 2001. Medical histories were reviewed, and a pediatric orth...

Congenital cervical kyphosis is a rare clinical condition. The purpose of this study was to review the surgical management and outcomes of 12 consecutive cases of congenital cervical kyphosis management by the same surgical team. The authors retrospectively analyzed the records of 12 patients (5 men and 7 women) with an average age of 18.4 years (range, 15-31 years) who underwent surgery for co...

BACKGROUND The efficacy of laminoplasty in patients with cervical kyphosis is controversial. The purpose of this study was to investigate the impact of the initial pathogenesis on the clinical outcomes of laminoplasty in patients with cervical kyphosis. MATERIAL AND METHODS A total of 137 patients with cervical spondylotic myelopathy (CSM) or ossification of the posterior longitudinal ligament ...

Surgical treatment of thoracolumbar burst fractures with posterior short-segment pedicle fixation usually provides excellent initial correction of kyphotic deformity, but a significant amount of correction can be lost afterwards. This study evaluates the clinical relevance of the short-segment pedicle fixation supplemented by laminar hooks (2HS-1SH) construct in the surgical treatment of thorac...

BACKGROUND Although thoracic vertebral malformations with kyphosis and scoliosis are often considered incidental findings on diagnostic imaging studies of screw-tailed brachycephalic breeds, they have been suggested to interfere with spinal biomechanics and intervertebral disc degeneration. It is however unknown if an abnormal spinal curvature also predisposes dogs to develop clinically relevan...
