I am just touching on #2... Compression fracture of L2. While many would wonder why any L1/L2 nerve impingement would cause sciatica, it is because the sciatic nerve is (can be) composed of nerves from the entire lumbar plexus and any IVD protrusion into the spinal canal can cause cord compression or some degree of spinal stenosis may have occurred as a result of the vertebral body compression also pushing into the canal and onto the cord. Radiation treatment could result in demineralization of the spine and lead to further instability and possible compression. And (from a chiropractic viewpoint) she is also showing L4/L5 vertebral body rotation, sacral tipping which could be coming from the obvious thoracolumbar instability from the fracture (note the ramrod appearance of the L1 and some of L2. Full spine thoracolumbar films would shed more light on this. Decompression therapy with spinal manipulation would not be contraindicated, depending on the acute nature of pain onset and/or etiology symptoms.

3. Define abduction and adduction.

1. Melanoma, squamous cell, basal cell
2. Hinge- elbow; pivot- axis/atlas; plane- intercapal; condyloid- wrist; ball-and-socket- shoulder; saddle- trapeziometacarpal
3. abduction- something moves away from the body in frontal plane (angle w/ midline increases), adduction- something moves toward body in frontal plane (angle w/ midline decreases)
