Abstract
We reported 11 cases of non-traumatic posterior interosseous nerve paralysis, 6 males and 5 females, respectively.
Patient’s age ranged from 19-72 years with a mean of 44.8 years. Posterior interosseous nerve was surgically explored in all patients. Nerve entrapment occurred in 5 patients, in 4 of them it happened at the supinator, called arcade of Frohse. In another patient symptoms were caused by a space occupying lesion that was finally diagnosed as a fibromatosis of bursal wall. In addition, nerve constriction was observed in 5 patients at the level of the posterior interosseous nerve trunk. External neurolysis was performed in all patients. Recovery from paralysis was observed between months 2-9 with a mean of 5.1 months after surgery. This result was satisfactory in our opinion, because we could perform surgery in all patients in a period of time relatively short following paralysis, 1-6 months with a mean of 4.2 months, respectively.
