Subsidence following anterior lumbar interbody fusion (ALIF): a prospective study.
BACKGROUND Anterior lumbar interbody fusion (ALIF) is a widely used surgical technique for disorders of the lumbar spine. One potential complication is the subsidence of disc height in the post-operative period. Few studies have reported the rate of subsidence in ALIF surgery prospectively. We prospectively evaluated the rate of subsidence in adult patients undergoing ALIF. METHODS Results we...
متن کاملAnterior Lumbar Interbody Fusion
Historical Background Anterior lumbar interbody fusion (ALIF) was first used AQ1 in the treatment of tuberculosis and lumbar spondylolis-thesis. 1−3 Although described by Capener 4 in 1932 as the " ideal'' operation for spondylolisthesis, he further elaborated that " the technical difficulties of such procedure, however, preclude their trial.'' This statement was soon to be proven wrong by nume...
متن کاملStability After Anterior Lumbar Fusion with Interbody Cages: A Radiostereometric Evaluation
Background: Interbody cage stabilization as a stand-alone procedure in lumbar spine fusion is questioned due to inconsistent mechanical effects registered in human cadaveric studies. Even segmental mobility exceeding the normal range of motion is described after cage implantation. For the anterior interbody cage fusion, this potential, undesired destabilization is explained by the resection of ...
متن کاملAnterior interbody fusion of the lumbar spine.
Anterior interbody fusion of the lumbar spine by the extraperitoneal technique was performed in 47 patients with incapacitating low-back pain due to spondylolisthesis (26 patients) or disc degeneration (21 patients). The mean age was 38.2 years. Forty-five patients were re-examined 2--6 years postoperatively. According to the patients' own evaluation at follow-up, 53 per cent were free or almos...
متن کاملEffects of Anterior Interbody Cages on Lumbar Foraminal Dimensions
INTRODUCTION: Anterior lumbar interbody fusion (ALIF) using threaded cages has been shown to reduce segmental motion and restore the disc space. The effectiveness of these stand-alone cages in restoration and maintenance of intervertebral foramens has received little attention. Foraminal height reduces an average of 6.5 mm following disc removal, and interbody cages may indirectly increase and ...
