All patients received a single non-fractionated dose of 700 centigray of radiation at an average of two days following surgery (range: 1 to 3 days).
Radiation therapy of 700 centigray administered within three days after the open reduction and internal fixation of a fracture/dislocation has the beneficial result of minimizing the effects of HO formation at the elbow.
They originally used 2000 centigray in a divided dose regimen over 10 days.
McAuliffe and Wolfson reported eight cases of excision of elbow heterotopic ossification followed by 1000 centigray radiation treatment in five fractions over seven days.
Pain was centered chiefly at the thoracolumbar junction and persisted despite regional irradiation with 3,500
centigray.
In previous studies using the comet assay, changes in DNA migration (comet length) were detected at low levels of x-irradiation, 12.5
centigrays (rads) in human lymphocytes (Singh and Stephens 1997) and 50
centigrays (rads) in human sperm (Duty et al.
Final height after treatment for childhood acute lymphoblastic leukemia: comparison of no cranial irradiation with 1800 and 2400
centigrays of cranial irradiation.
In addition, they received 800
centigrays of total-body radiation followed by a final chemotherapy dose.
