Lower spinal structure correlates well with positional behavior among mammals. Nonetheless, the functional morphology of the axial post-crania of australopithecines has received less attention than their appendicular skeletons. This paper presents a detailed description and comparative morphometric analysis of the australopithecine thoracolumbar vertebral series Stw-H8/H41, and examines spinal ...

Study Design. Prospective clinical study. Objective. This study compares the clinical results of anterior lumbar total disc replacement and posterior transpedicular dynamic stabilization in the treatment of degenerative disc disease. Summary and Background Data. Over the last two decades, both techniques have emerged as alternative treatment options to fusion surgery. Methods. This study was co...

STUDY DESIGN A retrospective radiological evaluation. PURPOSE To verify that PI is related with progression of IS as well as development of IS and to assess the differences of pelvic parameters between the L4 & L5 IS, as well as between single & two level IS. OVERVIEW OF LITERATURE High pelvic incidence (PI) has been known to be related with development of IS. However, the previous studies ...

BACKGROUND Given the dearth of normal values, we conducted a cross-sectional study of North American racially diverse children to determine normal values of interincisor distance and lower spine flexion. METHODS Demographs of 307 children aged 5-17 seeking treatment emergency care were obtained along with interincisor distance measured by incisor tooth-to-tooth gap, lower spine flexion measur...

of a male. The number of mounts attempted by a male was also scored and recorded. The results of all the experiments were converted to lordosis quotient (LQ), defined as a percentage of full lordosis response (perineum elevated, all four legs extended from the initial crouch position and the head at an angle of 450 from the floor) divided by the number of mounts. Each group consisted of six ani...

UNLABELLED The aim of the paper was to determine a correlation between the weight of a child's backpack, their body weight, and certain features of their body posture. MATERIAL AND METHODS The study group consisted of 109 children, all aged seven years. The parameters of body posture were determined using the Zebris Ultrasonic System. RESULTS The number of children carrying a school backpac...

BACKGROUND A prospective cohort study was performed to evaluate the clinical and radiological outcomes following posterior lumbar interbody fusion (PLIF) in patients treated with a PEEK cage compared to those treated with an autologous cage using the lumbar spinous process and laminae (ACSP). METHODS Sixty-nine consecutive patients with lumbar degenerative disc disease were randomly assigned ...

Nowadays, postural misalignments prevalence in students is increasingly evident and its early detection the best way to prevent complications adulthood. It also known that problems appear have association between them. The aim of this study was characterize spine, scapular pelvic girdles 213 school (124 males 89 females), aged 10 20 years, from Escola Básica e Secundária de Santa Maria (EBSSM)....

Discussion The PC population is not structurally different than the asymptomatic population. It will be the growth, in pathologic context, which disturb parameters. A lumbar lordosis which is not correlated with PI have to be consider like a result of the disease (postural troubles, neuro-motor disorders related with growth,...) and require a specific and early evaluation and treatment. Authors...

This study aims to assess the differences in the radiological and clinical results depending on the lordotic angles of the cage in posterior lumbar interbody fusion (PLIF). We reviewed 185 segments which underwent PLIF using two different lordotic angles of 4° and 8° of a polyetheretherketone (PEEK) cage. The segmental lordosis and total lumbar lordosis of the 4° and 8° cage groups were compare...
