The scarcest of the Confederate produced Alabama Buttons. Most often encountered in Army of Tennessee camps and battle sites. This one was found near Utoy Creek, GA. My pictures donât do this button justice as it looks way better in hand.
Intra-articular loose bodies are chondral, osseous, or osteochondral fragments located in the articular cavity. They derive from the internal surfaces of synovial joints including bone surfaces covered by hyaline cartilage and capsule lined by the synovial membrane.he ability of US to diagnose intra-articular loose bodies greatly depends on a high degree of suspicion of the examiner, related to the knowledge of radiographic and clinical findings. Nowadays, radiography is still the modality of choice when a loose body is suspected on clinical grounds.
Also known as zygapophyseal or apopphyseal joint, is a synovial joint between the superior articular process of one vertebra and the inferior articular process of the vertebra directly above it. There are two facet joints in each spinal motion segment. The facet joints are situated between the pedicle and lamina of the same vertebra and form the articular pillars that act to provide structural stability to the vertebral column as a whole. Together with the disc, the bilateral facet joints transfer loads and guide and constrain motions in the spine due to their geometry and mechanical function.
