Ankylosing spondylitis (AS) is a chronic inflammatory disease affecting axial skeleton
which progresses to involve whole spine forming a rigid "bamboo spine"1.
All the cases were assessed for bone mineral density from appendicular as well as axial skeleton
Ankylosing spondylitis (AS) is a chronic inflammatory rheumatic disease that primarily involves the axial skeleton
and the sacroiliac joint.
Presence of axial skeleton
distinguishes FIF from teratoma; however, it can be seen only in 91% of cases on imaging.
It is a chronic, progressive, multi-system inflammatory disorder which primarily involves the sacroiliac (SI) joints and the axial skeleton
The hallmark feature, as was the case in our patient, is symmetric osteosclerosis in the diametaphyseal regions of the long bones with relative sparing of the axial skeleton
and epiphyseal regions .
The commonest pathologies in our study were metastasis and tuberculosis which are more common in the axial skeleton
like spine as compared to the appendicular skeleton such as long bones.
1,2) Osteosarcoma is an aggressive, malignant neoplasm that can occur as a primary bone tumor, affecting the appendicular or axial skeleton
or, rarely, with a soft-tissue in origin (ie, extraskeletal osteosarcoma).
The device must be so operationally equipped and installed with full acquisition processing and includes all requirements (gamma and CT camera requirements, software and hardware requirements) to obtain optimum image quality in investigations (especially in bone studies - both axial skeleton
, peripheral joint zones with prosthetics) with the lowest possible radiation exposure for the patient and for the shortest possible duration (scan time).
The authors have organized the fifty-three chapters that make up the main body of their text in six sections, covering general considerations, axial skeleton
fractures, upper extremity fractures and dislocations, lower extremity fractures and dislocations, pediatric fractures and dislocations, and intraoperative imaging.
The axial skeleton
, particularly the posterior elements are the most favorable sites of the osteoblastoma and account for 40% of the total, followed by those occurring in the long bones of the lower extremity, which account for 20%.
The axis of Barilium is unknown; however, Delapparentia can be clearly differentiated from Barilium (Norman, 2011a) in the rest of the axial skeleton
