A comparative study for the usage of Fidji cervical cages after multilevel anterior cervical discectomy and fusion.

Background: Postoperative dysphagia is one major concern in the treatment for patients with cervical spine spondylosis by using anterior cervical discectomy and fusion (ACDF) with plating and cage system.

Purpose: To evaluate the influence of two types of surgery for multilevel cervical spondylotic myelopathy (CSM) on postoperative dysphagia, namely ACDF with cage alone (ACDF-CA) using Fidji cervical cages and ACDF with cage and plate fixation (ACDF-CP).

Methods: A retrospective study was performed in 62 consecutive patients with multilevel CSM, including 32 underwent ACDF-CA (group A) and 30 underwent ACDF-CP (group B).

Vitamin D improves the content of TGF-β and IGF-1 in intervertebral disc of diabetic rats.

Objective: The contents of transforming growth factor-β and insulin-like growth factor-1 in disc of diabetic rats were measured at three different periods after injected with 1,25-Dihydroxyvitamin D3, and compared with that in normal rats. The significance of content changes was also discussed.

Methods: Fourty-five Sprague-Dawley (SD) rats were divided into three groups, namely the experimental group (STZ+calcitriol), control group (STZ+citrate buffer), and normal group (citrate buffer).
