This is a meta-analysis to compare the results between laminoplasty and laminectomy followed by fusion for the patients with multilevel cervical compressive myelopathy. An extensive search of literature was performed in MEDLINE, Embase, the Cochrane library, CNKI, and WANFANG. The following outcome measures were extracted: the Japanese Orthopaedic Association (JOA) scores, cervical curvature in...

Study Design Retrospective cohort study. Objective To compare the clinical and radiographic outcomes of transforaminal lumbar interbody fusion (TLIF) and posterolateral lumbar fusion (PLF) in the treatment of degenerative spondylolisthesis. Methods This study compared 24 patients undergoing TLIF and 32 patients undergoing PLF with instrumentation. The clinical outcomes were assessed by visual a...

OBJECTIVE To evaluate the effectiveness of Pettibon spinal manipulation and anterior headweighting for correct cervical hypolordosis and forward head posture, quantified by measurements taken from pre and post intervention lateral cervical radiographs. METHODS A total of 15 subjects were selected for investigation at random. An initial seated lateral cervical radiograph was taken to evaluate ...

STUDY DESIGN This is a prospective study design. OBJECTIVE To test the interobserver and intraobserver reliabilities of 5 specific measures of global cervical sagittal alignment in patients with ankylosing spondylitis (AS), and to suggest a better means of measuring cervical sagittal alignment. SUMMARY OF BACKGROUND DATA The intraobserver and interobserver reliabilities of several different...

STUDY DESIGN Prospective cohort study. PURPOSE To study clinicoradiological parameters of zero-profile cage screw used for anterior cervical discectomy and fusion (ACDF). OVERVIEW OF LITERATURE Radiological parameters of various implants used for ACDF are available, but those for zero-profile cage are sparse. METHODS Patients with unilateral intractable brachialgia due to single-level cer...

Induction of lordosis as typical female sexual behavior in rodents is dependent on a mount stimulus from males and blood levels of estrogen. Periaqueductal gray (PAG) efferent neurons have been suggested to be important for lordosis behavior; however, the neurochemical basis remains to be understood. In this study, we neuroanatomically examined (1) whether PAG neurons activated by mating stimul...

BACKGROUND Loss of cervical lordosis is a significant factor in the development of degeneration of the spine with aging. This degenerative changings of the cervical spine would cause pressure effect on the cervical root and/or medulla spinalis. AIM Our goal is to understand the effect of the PEEK cage on cervical lordosis in the early postoperative period. Also, to interpret the effects of on...

Opening black box and the holistic concept of Milan Roth In experiments on the “Nervous Skeleton” and its way of growth Roth offered science on neurovertebral and neuro-osseous growth relations ,with tensionforces. Recent studies with MRI in idiopathic scoliosis confirm much of this11. If there is increased tension in the CNS, there must be increased contraction in muscles too, if their energy ...

To determine if helmet removal causes a significant increase in lordosis of the cervical spine in ice hockey players, we radiographically assessed the position of the cervical spine in subjects immobilized to a standard spine backboard wearing shoulder pads both with and without a helmet. Ten adult male volunteers (ages, 18 to 28 years) with no previous history of cervical spine injuries were f...

BACKGROUND Careful review of published evidence has led to the postulate that the degree of lumbar lordosis may possibly influence the development and progression of spinal osteoarthritis, just as misalignment does in other joints. Spinal degeneration can ensue from the asymmetrical distribution of loads. The resultant lesions lead to a domino- like breakdown of the normal morphology, degenerat...
