Ulnar Nerve Injury and Froment’s Test: A Case Report

Abstract

Traumatic, peripheral nerve injuries can be easily missed in the emergency department. The attending physician needs to maintain a high index of suspicion when reviewing patients with extremity injuries. We present a case of a stable, 28-year-old male sustaining penetrating trauma to his right forearm with resultant, isolated ulnar nerve transection. Clinical findings and related anatomy are discussed pertaining to this patient's injury, with specific reference to Froment's test. This is a useful clinical adjunct when reviewing potential ulnar nerve injuries, demonstrating disruption of specific motor innervation to the thumb when such pathology exists. As a result, compensatory hyperflexion occurs with attempted thumb adduction, due to intact median nerve innervation of flexor pollicis longus. Early recognition of this pathology, whether isolated or concomitant, allows for early appropriate referral and improved patient outcomes.

Impact of physiotherapy rehabilitation in subject with Monteggia fracture with compartment syndrome- A case report

“…After the median nerve, the ulnar nerve is the second most common neuropathy that occurs after a fracture of the forearm. This also leads to chances of developing complex syndromes (Cloete and Lahri, 2019;Li et al, 2021). In the upper limb fractures, the most affected is the radial nerve.…”

Some Aspects of Diagnosis and Surgical Treatment of Upper Extremity Nerve Injuries

“…Огнестрельная травма нервного ствола является самым тяжёлым видом поражения. При этом отсроченная операция приводит к потере мышечной массы, развитию необратимых изменений в собственных мышцах кисти [25,29].…”
