Cross-cultural adaptation, reliability and validity of the Greek version of the Spinal Appearance Questionnaire (SAQ) in patients with adolescent idiopathic scoliosis.

Purpose: The Spinal Appearance Questionnaire (SAQ) is a widely validated tool for assessing perceptions of spinal deformity in adolescent idiopathic scoliosis (AIS) patients. This study aimed to develop and validate a Greek version of the SAQ (GR-SAQ).

Methods: A cross-cultural adaptation of the SAQ following international guidelines was performed.

Posterior lumbar interbody fusion versus circumferential fusion using the B-Twin expandable spinal system.

We reviewed the medical files of 32 patients with degenerative disc disease, spinal stenosis, and spondylolisthesis who underwent posterior lumbar interbody fusion using the B-Twin system. In 12 of these patients, posterior lumbar interbody fusion has been supplemented with posterior lumbar-instrumented fusion (circumferential fusion) because of spinal instability. Clinical and functional outcomes were assessed.
