INTRODUCTION Perioperative irradiation is often combined with spine tumor surgery. Radiation is known to be detrimental to healing process of bone fusion. We tried to investigate bone fusion rate in spine tumor surgery cases with perioperative radiation therapy (RT) and to analyze significant factors affecting successful bone fusion. METHODS Study cohort was 33 patients who underwent spinal t...

PURPOSE To assess the remodelling process of the bone graft and fused bodies after non-instrumented anterior interbody fusion with autogenous iliac graft in patients with spondylosis, infections, fractures, or disorders of the cervical spine. METHODS 68 patients aged 18 to 58 years who underwent non-plated anterior lower cervical interbody fusion with an iliac graft were retrospectively studi...

Osteoradionecrosis, a rare complication of radiation therapy, is a slow progression disease which affects the surrounding structures of spinal components. It essentially weakens the soft tissue and bony configuration and can cause nerve impingement or cord compression. We describe a patient who underwent radiotherapy for thyroid cancer and presented with cervical kyphosis with anterolisthesis o...

As with many other aspects of the foot, the rheumatoid foot, historically, has been treated symptomatically. If there is a painful tenosynovitis, synovectomy; a painful joint not responding to drug treatment, fusion; bony prominences (including metatarsal heads), excision; if the structure collapses, a valgus 'insole'; and if all else fails, bespoke footwear and discharge. But is this good enou...

During the years from 1948 to 1956 a lumbo-sacral inter-body spinal fusion was done on forty-eight patients through a posterior approach. The operations have been divided chronologically into three groups. Improvements in the surgical technique were added in the two later groups, so that ultimately a new operative procedure was evolved and used in the last group, which gave the highest rate of ...

Introduction: Spinal tuberculosis is the most common form of skeletal tuberculosis with the dorsolubar region being the most commonly affected region. The most dreaded complication of spinal tuberculosis is tubercular paraplegia seen in around 40% of the cases. There has been controversy regarding the surgical treatment of the disease and also the approach to be used and the use of implants. In...

A patients with atlantoaixial instability and osodontoideum underwent atlantoaixial fusion (Harms and Melcher technique) with demineralized bone matrix. But, unfortunately, the both pedicle screws in C2 were fractured within 9 weeks follow-up periods after several suspected episode of neck hyper-flexion. Fractured screws were not contact to occipital bone in several imaging studies, but it coul...

Spine disorders and intervertebral disc degeneration are considered the main causes for the clinical condition commonly known as back pain. Spinal fusion by implanting autologous bone to produce bony bridging between the two vertebrae flanking the degenerated-intervertebral disc is currently the most efficient treatment for relieving the symptoms of back pain. However, donor-site morbidity, com...

STUDY DESIGN A retrospective study. PURPOSE To evaluate the surgical results of computer-assisted C1-C2 transarticular screw fixation for atlantoaxial instability and the usefulness of the navigation system. OVERVIEW OF LITERATURE We used a computed tomography (CT)-based computer navigation system in planning and screw insertion in Magerl's procedure, which provides the most rigid atlantoax...

BACKGROUND Although autogenous iliac bone graft (AIBG) remains the gold standard for spine fusion, harvesting morbidity has prompted the search for alternatives especially for multi-segment fusion. This study aimed to evaluate the efficacy of using demineralized bone matrix (DBM) as a substitute of AIBG for long instrumented posterolateral fusion (≧ three-level fusion). METHODS A total of 47 ...
