PURPOSE Anterior cervical discectomy and fusion (ACDF) has become a common spine procedure, however, there have been no previous studies on whole spine alignment changes after cervical fusion. Our purpose in this study was to determine whole spine sagittal alignment and pelvic alignment changes after ACDF. MATERIALS AND METHODS Forty-eight patients who had undergone ACDF from January 2011 to ...

BACKGROUND The association between cervical lordosis (sagittal alignment) and neck pain is controversial. Further, it is unclear whether spinal manipulative therapy can change cervical lordosis. This study aimed to determine whether cervical lordosis changes after a course of spinal manipulation for non-specific neck pain. METHODS Posterior tangents of C2 and C6 were drawn on the lateral cerv...

introduction: after low back pain, the neck pain is the most prevalent pain among (especially elderly) peoples. the purpose of this study was to determine the effect of one period of exercise program on subjects neck rom and chronic neck pain. materials and methods:  for executing this study 60 elderly patient (24 males and 36 females) with mean age 56± 4.5 years old and 71± 4.4 kg with chronic...

OBJECTIVE This study investigates the impact of isometric contraction of anterior cervical muscles on cervical lordosis. METHODS 29 volunteers were randomly assigned to an anterior head translation (n=15) or anterior head flexion (n=14) group. Resting neutral lateral cervical x-rays were compared to x-rays of sustained isometric contraction of the anterior cervical muscles producing anterior ...

STUDY DESIGN Prospective study. OBJECTIVE To identify the impact of laminoplasty on range of motion (ROM) and sagittal alignment of the cervical spine. SUMMARY OF BACKGROUND DATA Cervical laminoplasty is an effective procedure decompressing multilevel spinal cord compression. Preoperative lordosis of the cervical spine is a prerequisite for laminoplasty, and maintaining postoperative lordos...

STUDY DESIGN Retrospective case series. PURPOSE To elucidate the impact of postoperative occiput-C2 (O-C2) angle change on subaxial cervical alignment. OVERVIEW OF LITERATURE In the case of occipito-upper cervical fixation surgery, it is recommended that the O-C2 angle should be set larger than the preoperative value postoperatively. METHODS The present study included 17 patients who unde...

Background & Aims: Cervical spine is prone to various abnormalities and sport injuries. There is still no non-aggressive measurement instrument with high reliability for easy and rapid assessment of cervical spine secondary complications. The aim of this research was to investigate the validity of goniometric method for cervical lordosis measurement through radiography. Method: In this study, 1...

A retrospective analysis of 500 patient radiographs was conducted to measure the clinical correlation of cervical lordosis measurements and incidence of motor vehicle accident (MVA). Five hundred lateral cervical radiographs were selected at random from the practice of one of the authors (DLM). The C1-7 angle of the cervical curve was then measured by two blinded examiners. Inter-examiner relia...

After performing anterior cervical corpectomy or discectomy for cervical spondolytic myelopathy or radiculopathy, iliac crest bone graft and fibular auto- or allograft is often used to achieve arthrodesis in the cervical spine. The purpose of this study was to evaluate the use of a cylindrical titanium mesh and locking plate system as an alternative technique in achieving anterior cervical fusi...
