Spinal Fusion for Kyphosis in Achondroplasia

Journal of Pediatric Orthopaedics, 2004
Persistent thoracolumbar kyphosis in patients with achondroplasia is typically prevented with sitting modifications and bracing. When the kyphosis persists and progresses despite bracing, spinal fusion is indicated to prevent further progression and neurologic complications.

Cell technologies for spinal fusion

The Spine Journal, 2005
For a successful spinal fusion to occur, several vital elements are necessary. They consist of the presence of the bone-forming cell (osteoblast) or its precursor, the appropriate biological signals directing bone synthesis, and a biocompatible scaffold on which the process can occur.

Coblation of spinal endplates in preparation for interbody spinal fusion

Journal of Clinical Neuroscience, 2006
Posterior lumbar interbody fusion (PLIF) and anterior lumbar interbody fusion (ALIF) have become routine alternatives to intertransverse process fusion. The use of Coblation (ArthroCare Corporation, Sunnyvale, CA) allows for routine and reproducible removal of cartilaginous endplate down to the bony endplate.

Animal Models of Spinal Instability and Spinal Fusion

2020
This chapter reviews general concepts of spinal instability and stabilization. It focuses on animal models that have been used to evaluate novel osteoinductive growth factors or implantable, fusion enhancing biomaterials. The chapter discusses the models that enable examination of systemic factors influencing the fusion process.

Rationale for Spinal Fusion in Lumbar Spinal Stenosis

Spine, 1989
In order to define the indications for spinal fusion in patients undergoing decompression for lumbar spinal stenosis, 114 patients surgically treated were reviewed. Follow-up was 24 to 108 months. Patients were grouped into four categories: 15 with lateral recess stenosis, 45 with central-mixed stenosis, 43 with stenosis following prior lumbar surgery ...

Bracing of Spinal Fusions [PDF]

, 1990
The choice of the postoperative orthosis has always reflected the surgeon’s perceptions of the strengths and limitations of the surgical construct. Before the development of instrumentation systems, early spinal surgeons focused on creating a surgical procedure that would consistently result in a fusion.

Kinematic Analysis of Spinal Fusions

Investigative Radiology, 1976
Two cases with clinical suspicion of incompletely healed anterior fusion between L5 and S1 were examined by means of a roentgen stereophotogrammetric method. In both cases a pseudarthrosis was found. The method makes it possible to disclose rotations and translations between veretebrae with an accuracy of about 0.2degree and 30-120 mum, respectively.

Outcome of lumbar spinal fusion surgery in obese patients: a systematic review and meta-analysis.

The Bone & Joint Journal, 2015
The aim of this study was to determine whether obesity affects pain, surgical and functional outcomes following lumbar spinal fusion for low back pain (LBP).

Biomechanics of Spinal Fixation and Fusion

Spine, 1991
Recent experiments have shown that in the sheep spine a displacement of 5.2 mm and a strain of 36% was present at the lumbosacral joint, where fusion almost never occurred when multiple, small (5 mm x 14 mm) cancellous and corticocancellous bone grafts were placed in an interlocking fashion across the decorticated lamina of the lumbar spine and sacrum.

Assessing Spinal Instability or Indications for Spinal Fusion

1990
Every year 10 million Americans have acute low back pain; only 286,000 (0.04%) require an operation, of which approximately one-fourth (70,000) are spinal fusions.1 In the United States, 2% of the adult population have had a previous lumbar spinal operation, and it is probable there are 500,000 to 1,000,000 living adults who have had a lumbar spinal ...
