A case of clinically diagnosed repetitive strain injury was referred for investigation to rule out the possibility of an occult bone disease.
The patient was a female keyboard operator who had pain and tenderness over the flexor muscles of the right hand and arm.
The pain was severe and almost constant.
The authors observed an increase in Tc-99m MDP delivery to the affected forearm during the dynamic sequence of a three-phase bone scintigram, indicating increased blood flow compared to the contralateral side.
The same result was achieved using quantitative blood flow measurements with the Doppler technique and Tc-99m HMPAO perfusion imaging.
These findings agree with recent studies that suggest increased total arm blood flow in repetitive strain injury and may provide an easy screening method.
