1. Osteoporosis should be classified as being with or without symptoms.
2. The type with symptoms (the acute bone atrophy of Sudeck) responded to roentgenotherapy in five out of six cases treated.
3. The roentgen-ray dosage is of such a type that erythema or burns will not occur.
4. In some cases of loss of function in joints associated with an inflammatory condition of the adjacent soft parts, the roentgen-ray apparently relieved the pain which was producing muscle spasm, and function of the joint returned.
5. The suggested roentgenotherapy for osteoporosis is purely empirical, and further proof of its true value is necessary.
