Reconstructing Pinch Strength after Ulnar Nerve Injury by Transferring the Opponens Pollicis Motor Branch

Jayme Augusto Bertelli

Abstract: Background: With ulnar nerve injuries, paralysis of the first dorsal interosseous(FDI) and adductor pollicis muscle weakens the patient’s pinch. In the palm, we transferred the opponens pollicis motor branch (Opp) to the deep terminal division of the ulnar nerve (DTDUN) for pinch reconstruction. Methods: Sixteen patients with ulnar nerve injuries around the elbow underwent reconstruction and were followed post-operatively for a minimum of 14 months. The… Show more

“…If concomitant distal suprascapular nerve injury is suspected, for example, in cases with scapular or distal clavicular fracture or shoulder trauma, the suprascapular nerve can be explored distally via a crescentic clavicular osteotomy, and the nerve followed through the suprascapular notch and visualized entering the muscle (Figure 4). This enables identification of a distal nerve injury, which can be bypassed with nerve transfer more distal and nearer its entry into the muscle (Bertelli, 2023).…”

“…(2019) to specifically target the first dorsal interosseous and adductor pollicis to restore pinch strength. In a series of 16 patients undergoing this nerve transfer, 15 achieved functional reinnervation of first web space muscles with a mean improvement in subterminal pinch strength from 0 to 2.4 kg, representing recovery of 61% of strength in comparison to the contralateral side (Bertelli, 2023).…”
