Background. The treatment of thoracic kyphosis and lumbar lordosis with the C-D method remains controversial. Material and methods. The lateral radiographs of 70 patients with King I, II, III, IV idiopathic scoliosis, treated with C-D instrumentation, were retrospectively analyzed. The average age was 14 +/- 1.8 years. Thoracic kyphosis between T2 and T12 and lumbar lordosis between L1 and L5 w...

We have evaluated the use of a synthetic porous ceramic (Triosite) as a substitute for bone graft in posterior spinal fusion for idiopathic scoliosis. In a prospective, randomised study 341 patients at five hospitals in the UK and France were randomly allocated either to autograft from the iliac crest or rib segments (171) or to receive Triosite blocks (170). All patients were assessed after op...

BACKGROUND Serial cast correction by using the Cotrel derotation technique is one of several potential treatments for progressive infantile scoliosis. This study reviews our early experience to identify which, if any, patients are likely to benefit from or fail this technique. METHODS We followed all patients treated at our institutions for progressive infantile scoliosis since 2003 prospecti...

Study Design Retrospective cohort. Purpose To review the clinical presentation of operated patients with delayed neurological deficits after osteoporotic vertebral fractures (OVFs). Overview of Literature Delayed neurological deficits can occur from 1 week to 5.7 months after OVFs. Baba has reported 78% good-to-excellent improvement (i.e., ≥50%) after 20 posterior (Cotrel-Dubousset) and 7 a...

BACKGROUND [corrected] Three-dimensional surgical correction of scoliosis was introduced in the 1980s by Cotrel-Dubousset. Initially only laminar and pedicular hooks, two rods (correcting and stabilizing), and transverse links joining both rods were used to correct and stabilize the spine. When implant systems had been developed and modernized, transpedicular screws in the lumbar segment were u...

BACKGROUND To evaluate the severity of lumbar spine pain and the extent to which it affects everyday activities in patients treated surgically for scoliosis. MATERIALS AND METHODS Sixty female patients who had undergone Cotrel-Dubousset instrumentation for idiopathic scoliosis were asked to complete a questionnaire. The mean age of the patients at the time of surgery was 15.5 years, and the m...

Scoliosis is a three-dimensional deformation of the spine that can be treated by vertebral fusion using surgical instrumentation. However, the optimal configuration of instrumentation remains controversial. Simulating the surgical maneuvers with personalized biomechanical models may provide an analytical tool to determine instrumentation configuration during the pre-operative planning. Finite e...

STUDY DESIGN A retrospective study of tissue surrounding titanium alloy spinal implants was performed using histological and electron microprobe analysis. PURPOSE To identify the metal debris generated by spinal implants, and then to evaluate the electron microprobe analysis results and the histological response of soft tissue surrounding the spinal implants. OVERVIEW OF LITERATURE Microsco...

BACKGROUND Long-term outcomes of patients undergoing extensive fusions for adolescent idiopathic scoliosis (AIS) have conflicting results. Moskowitz found uninstrumented scoliosis fusion patients had similar back pain as a normal age matched population. Recently, long-term outcomes of patients with Harrington rod instrumentation were reviewed and found similar functional outcome scores to non-s...
