Pedicle screw constructs have been shown to increase fusion rates in the lumbar spine. Manufacturers have created pedicle screws with one or two degrees of freedom built into the screw head to allow for easier incorporation of the interlock...

The aim of this work was to evaluate the efficacy of dynamic anterior cervical plates following one-level anterior corpectomy with fusion (ACF) (i.e., C5-7) and two- to four-level ACF with posterior wiring and fusion (PWF). Dynamic plates (...
Can the thoracic kyphosis be modeled with a simple geometric shape? The results of circular and elliptical modeling in 80 asymptomatic patients [0.03%]

Implant retrieval programs have been effective in understanding implant failure and biomaterial compatibility in joint arthroplasty; however, its application has not been extended extensively to the assessment of spinal constructs and impla...
Anatomic and radiographic considerations for placement of transiliac screws in lumbopelvic fixations [0.03%]
腰骶骨盆固定手术中经髂骨螺钉置入的解剖和放射学考量

Lumbopelvic fixation in spinal and pelvic surgery relies on rods or screws as an iliac anchor. Secure placement of screws with maximum diameter and length for the greatest pullout strength requires knowledge of the iliac structure and of in...
Diagnosis of symptomatic disc by magnetic resonance imaging: T2-weighted and gadolinium-DTPA-enhanced T1-weighted magnetic resonance imaging [0.03%]
