Pathogenic variants of sacsin (SACS) gene cause autosomal recessive Spastic Ataxia of Charlevoix-Saguenay (ARSACS). It is a hereditary neurological disorder manifested with gait ataxia, intentional tremor, lower limb pyramidal signs and pes cavus. It was originally described in the late 1970s and […]

Anterior Lumbar Interbody Fusion (ALIF) is a commonly performed spine surgery procedure used to treat lumbar conditions such as degenerative disc disease, spondylolisthesis, and spinal deformities. Traditionally, it has been performed using open and mini-open surgical techniques. Recently, however, […]

Chronic low back pain (CLBP) is a highly prevalent health problem. Recent research has suggested that disruption of body perception might contribute to the problem and represent a target for treatment. Valid and reliable outcome measures are required to understand the relationship between disrupted […]

Spinal Ewing's Sarcoma is a rare tumour predominantly affecting children and adolescents. We describe the case of an 18-year-old male patient who first presented with a primary extradural cervical Ewing's sarcoma tumour, and 5 years later had a recurrence with thoracolumbar and lumbosacral […]
