Nerve Transfers for Brachial Plexus Reconstruction in Patients over 60 Years

Abstract

Negative expectations regarding nerve reconstruction in the elderly prevail in the literature, but little is known about the effectiveness of nerve transfers in patients with brachial plexus injuries aged over 60 years. We present a series of five patients (1 female, 4 male) aged between 60 and 81 years (median 62.0 years) who underwent nerve reconstruction using multiple nerve transfers in brachial plexopathies. The etiology of brachial plexus injury was trauma (n = 2), or iatrogenic, secondary to spinal surgical laminectomy, tumor excision and radiation for breast cancer (n = 3). All but one patient underwent a one-stage reconstruction including neurolysis and extra-anatomical nerve transfer alone (n = 2) or combined with anatomical reconstruction by sural nerve grafts (n = 2). One patient underwent a two-stage reconstruction, which involved a first stage anatomical brachial plexus reconstruction followed by a second stage nerve transfer. Neurotizations were performed as double (n = 3), triple (n = 1) or quadruple (n = 1) nerve or fascicular transfers. Overall, at least one year postoperatively, successful results, characterized by a muscle strength of M3 or more, were restored in all cases, two patients even achieving M4 grading in the elbow flexion. This patient series challenges the widely held dogma that brachial plexus reconstruction in older patients will produce poor outcomes. Distal nerve transfers are advantageous as they shorten the reinnervation distance. Healthy, more elderly patients should be judiciously offered the whole spectrum of reconstructive methods and postoperative rehabilitation concepts to regain useful arm and hand function and thus preserve independence after a traumatic or nontraumatic brachial plexus injury.

The Promise of Personalized Peripheral Nerve Surgery

“…Alternatively, costovertebral exarticulation of the first rib may be a viable alternative in patients with neurogenic thoracic outlet syndrome, as demonstrated in a retrospective clinical study [ 11 ]. Furthermore, research on nerve transfers for brachial plexus reconstruction in patients over 60 years underscores the importance of age-specific considerations in surgical decision-making [ 12 ]. By tailoring treatment strategies to the unique needs and physiological characteristics of older patients, clinicians can optimize outcomes and enhance quality of life, reaffirming the principle of personalized care in peripheral nerve surgery.…”
