Methods

Our study group consists of Adolescent Idiopathic Scoliosis patients who presented consecutively in our institution from June to September 2010. They were either seen in outpatient clinics or as elective admissions prior to operative correction of their spinal deformity. The presence of an idiopathic scoliosis deformity and the absence of any abnormal neurological symptoms were our inclusion criteria. They were examined by two clinicians for the presence of IRR using a tendon hammer. As part of their management all such patients routinely undergo an MRI scan in our Trust to investigate for the presence of intraspinal pathology. When the IRR was present we looked at their MRI scans to identify any relevant abnormalities.

Results: We identified 100 subjects. There were 72 females and 28 males with an average age of 15 years. The IRR was present in 12 cases and in 6 of them the sign was present bilaterally. There were no further associated signs or symptoms. All cases had recently undergone MRI of their whole spine and their investigations did not demonstrate any abnormalities in the lower cervical spine.
