New blood vessels + fibroblasts + osteocytes
(Not too sure about timeline for osteocytes but this looks like it may contain woven bone??)

Fibrous nonunion
(Note the wide gap between the bone; pieces of bone weren’t closely enough aligned for complete healing)
Most common fracture in kids?

Salmonella
(Bone marrow > 50% cellularity = classic of SCD)

Tertiary syphilis
Neuropathic joint disease, neurosyphilis, CV syphilis
