Posterior interosseous nerve syndrome after pneumatic hammer use: An uncommon condition.
AMERICAN JOURNAL OF INDUSTRIAL MEDICINE(2017)
Abstract
This case report presents a 27 year-old manual worker with right wrist extension deficit after pneumatic hammer handling. MRI and electromyographic studies revealed partial compromise of the posterior interosseous nerve (PIN) proximal to the branch for the extensor digitorum communis. The patient enrolled a 6-week rehabilitation period and recovered without remaing symptoms. PIN syndrome has mostly been associated with compressive neuropathies of the upper limb, but has seldom been reported in labor contexts. This case exemplifies an unusual presentation of PIN compression without a definite imaging diagnosis, where clinical presentation and electrodiagnostic studies are paramount for an accurate approach and understanding of the underlying condition.
