The incident happened in November 2007 when the 46-year-old inmate whacked the little finger of his right hand on the edge of the table, according to local newspaper Arbetarbladet.
For the next ten weeks he was forced to wear a plastic splint to support the finger which was tender and swollen.
The prisoner made a personal injury claim over the matter.
The Legal, Financial and Administrative Services Agency (Kammarkollegiet) took the opinion of doctors and photographic evidence into consideration before making the decision.
They concluded that he suffered pain, injury and scarring and was therefore rightfully awarded financial compensation.
