Glassman is an osteogenesis imperfecta, also known as brittle bone disease, characterized by generalized osteoporosis, blue eyes, progressive deafness and brittle bones. The patient’s pathology is characterized by a significant impairment of both chondrogenic and intramembranous bones, a thin cortical stem, an eggshell-like appearance in severe cases, and a widening of the epiphysis, which is characterized by fragile bones, easy fracture, and bending and deformity. Clinical manifestations include short stature, curvature and deformity of the head, spine and limbs, increased transparency of the sclera, exposure of the choroid, blue eyes in 90% of patients, progressive deafness in some patients, laxity of joint ligaments, increased joint mobility, easy dislocation of joints, fragile nails and hair, osteoporosis in general, and even cystic degeneration. Long bones are most prominent in performance.
