  42. Nonunion – Failure of the fragments of a broken bone to knit together.
  43. Osteoarthritis – Arthritis typically with onset during middle or old age that is characterized by degenerative and sometimes hypertrophic changes in the bone and cartilage of one or more joints and a progressive wearing down of apposing joint surfaces with consequent distortion of joint position and is marked symptomatically especially by pain, swelling, and stiffness.
