Abstract Introduction Recently, a paper was published containing the long-term results of the first ‘modern’ double rod instrumentation, the Cotrel–Dubousset instrumentation. Results showed an unexpected high rate of reoperation of nearly 50% due to late infections or chronic back pain occurring after surgery. Further research into the longterm complications of spinal fusion surgery in adolesce...

Fusion to the sacrum presents as a complex and difficult technical procedure with outcomes which have been up until recently, relatively poor, with high pseudoarthrosis rates and associated with the development of so called flat back deformity or loss of lumbar lordosis. Previous reports from the morbidity committee of The Scoliosis Research Society in the late 1970’s indicated that this did no...

Introduction According to the ‘vicious cycle’ hypothesis proposed by Dr Stokes, sensitivity to load has been implicated in the progression of spinal deformity during growth due to the reaction of vertebrae to mechanical loads on their growth plate. Mechanical loads on the vertebrae are altered by the mechanical stiffness of the spinal implant. Unfortunately, the relationship between the implant...
