Locomotor Disability in the Elderly — Disease or Decay?

Case 1 The patient had straightforward nutritional osteomalacia. She lived alone in a country cottage and never went out (Hodkinson et al. 1973). She had been unable to walk for three months. Her oral intake of vitamin D was probably less than 15 iu daily. The plasma calcium was 5.5 mg/100 ml, and alkaline phosphatase only 13 K-A units/100 ml. She had Looser zones in the forearms, and histological osteomalacia. Vitamin D was given in an initial dose of 1.25 mg daily. She improved rapidly and was able to walk well until her death at 93.
