Clinical Evaluation of Allogeneic Growth Factor in Cervical Spine Fusion

evaluation of adjacent segment degeneration after cervical spine surgery: arthroplasty versus fusion

background : anterior cervical discectomy and fusion (acdf) is an effective treatment for disc herniations ; but some studies demonstrated that in the untreated levels adjacent to a fusion, increased motion might lead to an increased risk of adjacent segment degeneration (asd). on the other hand, methods of cervical disc arthroplasty (cda) have improved. the aim of this study is to evaluate and...

evaluation of sadr eminence in safavid period

چکیده: یکی از دوره های مهم تاریخی ایران به لحاظ تأمین استقلال ملی مذهبی و حتی تأثیر آن بر فرهنگ و مذهب ایرانیان، دوره صفویه است. رسمیت دادن و رواج مذهب شیعه توسط شاه اسماعیل اول، یکی از مهمترین اقدامات این دولت محسوب می شود. بنابراین برای اجرای این سیاست، وی منصب صدارت را به عنوان منصبی مذهبی- حکو متی ایجاد کرد .این منصب از دوره ی تیموریان ایجاد شده بود ولی در اواخر این دوره اهمیت بیشتری یافت...

Outcomes of instrumented fusion in the pediatric cervical spine.

OBJECT The most common cause of cervical spine arthrodesis in the pediatric population is instability related to congenital or traumatic pathology. Instrumenting the cervical spine can be challenging given smaller anatomical structures, less ossified bone, and future growth potential and development. Studies in adult patients have suggested that using screw constructs results in improved outcom...

Biomechanical evaluation of stand-alone interbody fusion cages in the cervical spine.

STUDY DESIGN An in vitro biomechanical investigation of the immediate stability in cervical reconstruction. OBJECTIVES The purpose of this study was to compare the segmental stability afforded by the interbody fusion cage, the anterior locking plate, and the "gold standard" autograft. SUMMARY OF BACKGROUND DATA Recently, interbody fusion cage devices have been developed and used for cervica...
