Innervation of the Wrist Joint and Surgical Perspectives of Denervation

Ultrasound-guided supracondylar radial nerve block for Colles Fractures in the ED

“…As shown in a previous cadaver study [1], most innervation to the dorsal distal radius originates from the posterior interosseus nerve. To the best of our knowledge, our cases are the largest series in the English literature that screened the effectiveness of the ultrasound (USG)-guided supracondylar radial nerve block on closed reduction of the distal radius fractures.…”

Proprioception of the Wrist Following Posterior Interosseous Sensory Neurectomy

“…24 These nerves include the posterior interosseous nerve, deep and dorsal branches of the ulnar nerve, superficial radial nerve, lateral antebrachial cutaneous nerve, medial antebrachial cutaneous nerve, palmar cutaneous branch of the median nerve, and anterior interosseous nerve. 24 Charcot arthropathy is unlikely to develop after PISN because none of the other branches that innervate the wrist joint are disturbed.…”

Evidence of Wrist Proprioceptive Reflexes Elicited After Stimulation of the Scapholunate Interosseous Ligament

“…Furthermore, it cannot be identified using sonographic techniques, which eliminated the possibility of inserting a capsular stimulating electrode to evaluate possible reflex reactions. The dorsal wrist capsule, innervated by terminal branches from the posterior interosseous, dorsal radial and ulnar sensory nerves, 41 has not been studied with regard to presence of proprioceptive nerve endings. Hence, we currently lack information on its possible role in wrist proprioception.…”
