Spinal osteosarcomas are quite rare and the optimal treatment strategy is unknown. We report a series of 9 cases of osteosarcoma of the spine treated with intralesional resection and adjuvant combination therapy in order to evaluate their clinico-pathological correlation, recurrence rate and survival. Between 1980 and 2009, nine histologically confirmed cases of primary conventional osteogenic sarcoma of the spine were identified from Scottish Bone Tumour Registry. This prospectively collected registry database was retrospectively reviewed.Introduction

Aneurysmal bone cysts are uncommon benign lesions affecting the spinal column. They mostly occur in the lumbar spine and have a propensity to affect adjacent vertebrae. We describe 14 aneurysmal bone cysts affecting the spinal column from the Scottish Bone Tumour Registry with regard to assess the incidence, demography, biological behaviour and recurrence rate. We identified 14 patients with aneurysmal bone cysts affecting the spinal column. Case notes and radiographs were retrospectively reviewed from the Scottish Bone Tumour registry.Introduction
Materials and Methods
A consecutive series of 85 patients with Duchenne’s muscular dystrophy who underwent spinal fusion over a period of 16 years was followed up with regard to the progression of the scoliosis and pelvic obliquity. Of 74 patients with adequate radiographic follow-up, 55 were instrumented with the Luque single-unit rod system and 19 with the Isola pedicle screw system; seven were instrumented to L3/4, 42 to L5, 15 to S1 and 10 to the pelvis with intrailiac rods. The mean period of follow-up was 49 months (SD 22) before and 47 months (SD 24) after operation. There was one peri-operative death and three cases of failure of hardware. The mean improvement in the Cobb angle was 26° and in pelvic obliquity, 9.2°. Fusion to L3/4 achieved a poorer correction of both curves while intrapelvic rods, achieved and maintained the best correction of pelvic obliquity. Fusion to S1 did not provide any benefit over more proximal fusion excluding the sacrum, with regard to correction and maintenance of both angles. The Isola system appeared to provide and maintain a slightly better correction of the Cobb angle.
