Posterior interosseous nerve palsy is a rare syndrome frequently
unrecognized, while the clinical presentation is characteristic : finger extension
paresis associated with wrist extension in radially deviated position. Here, we
assessed our results of surgical treatment. METHODS:
A 20-year retrospective
study was carried out in our unit. Analysis of causes and an assessment of
postoperative functional outcome were performed. Our study was compared with
literature data. RESULTS: Eighteen cases were treated with a predominance in men
manual workers. The etiology of the posterior interosseous nerve palsy was tumor
in four cases, traumatic in two cases, iatrogenic in two cases and idiopathic in
ten cases. In seven of these ten cases, compression under the arch of the
extensor carpi radialis brevis was found. The postoperative results were
satisfactory with full recovery in nine out of fifteen cases treated by
neurolysis, depending on the duration of the paralysis. In the literature, we
found 264 cases over 50 years through a variety of clinical cases and five case
series. A predominance of tumor etiology was found. CONCLUSION: Ignorance of the
clinical presentation of a posterior interosseous nerve palsy frequently leads to
misdiagnosis. Early complete neurolysis enables a satisfactory functional recovery.
