The most common cause of iatrogenic flatback syndrome is Harrington distraction instrumentation extending into the lower lumbar spine. Other common causes and exacerbating factors include failure to enhance regional lordosis during lumbar fusion for degenerative spondylosis, development of pseudarthrosis or postoperative loss of correction, development of kyphosis at the thoracolumbar junction,...

ABSTRACT Conventional chondrosarcomas rarely metastasize and it is extremely unusual to see multicentric- behaviour in malignant cartilage tumour. We report a 40 year old lady with presentation of two non-contiguous metachronous foci of low to intermediate grade of chondrosarcoma over left pelvic bone and right scalp respectively in the absence of pulmonary or visceral metastasis. KEY WORDS v...

Spinal trauma is a common problem in modern Orthopedics. Spine surgery has recently been transformed significantly by the growth of minimally invasive (MIS). Easily acceptable to patients as less with smaller incisions, MIS often perceived superior traditional open spine surgery. This study aims functional outcome (MIS) posterior thoracolumbar instrumentation fractures. Present was prospective ...

Adolescent idiopathic scoliosis (AIS) is usually instrumented using a posterior approach. Hardware removal may be performed for specific clinical reasons. Little data is available on whether removal influences curve magnitude. The aim of the paper is to evaluate the impact of instrumentation removal on curve progression, and the safety and efficacy of the procedure. We analyzed 59 patients who ...

A 38-year-old man was operated with posterior spinal decompression and pedicle screw instrumentation for his L2 fracture with incomplete neurological deficit. In the recovery, he complained of blindness in both eyes after twelve hours. Computed tomographic scan and magnetic resonance angiography revealed bilateral occipital lobe infarcts. He remained permanently blind even after three years fol...

with decompression of the spinal cord, is now widely used for the surgical management of infection, especially tuberculosis (Hodgson and Stock 1960), spinal tumours (Harrington 1981) and congenital spinal deformity (LeathermanandDickson1979). Therehasthusbeenan increasing interest in a direct surgical approach to vertebral bodies. Surgical approaches which allow exposure of the anterior aspect ...

PURPOSE To describe a technique involving posterior 360-degree stabilisation of the upper thoracic spine: spinal cord decompression, posterior vertebral body replacement, and then posterior instrumentation and intercostal posterolateral vertebral stabilisation. METHODS Three men and 4 women aged 41 to 77 (mean, 58) years underwent posterior 360-degree stabilisation of the upper thoracic spine...

BACKGROUND Conventional (rigid) fusion instrumentation is believed to accelerate the degeneration of adjacent discs by increasing stresses caused by motion discontinuity. Fusion instrumentation that employs reduced rod stiffness and increased axial motion, or dynamic instrumentation, may partially alleviate this problem, but the effects of this instrumentation on the stresses in the adjacent di...

OBJECT The most common cause of cervical spine arthrodesis in the pediatric population is instability related to congenital or traumatic pathology. Instrumenting the cervical spine can be challenging given smaller anatomical structures, less ossified bone, and future growth potential and development. Studies in adult patients have suggested that using screw constructs results in improved outcom...
