C7 Nerve Transfer: Past, Present and Future
The talk features the evolution of contralateral C7
transfer, covering both experimental studies and
clinical experience. Various studies have been
conducted to answer questions concerning
contralateral C7 transfer. What is the functional
muscle innervation of each brachial plexus nerve
root? What is the never fiber composition and
distribution in C7 nerve root? Why is C7 nerve root
dispensable and compensable, even in ipsilateral C7
transfer? What are the major considerations in
selective/hemi-contralateral C7 root transfer and
ipsilateral C7 transfer? Should contralateral C7
transfer be performed in a staged fashion? Can
contralateral C7 nerve root be used to neurotize
multiple recipient nerves? What is the optimal way
and combination of doing so? New techniques such
as prespinal routing in contralateral C7 transfer will
be mentioned. Major challenges in C7 transfer,
65
challenges in C7 transfer, especially the difficulty in
achieving independent movement, are discussed.
Preliminary results of studies on brain plasticity following
contralateral C7 transfer will be reported. Other
indications of C7 transfer, e.g. repair of Bell’s palsy,
accessory nerve injury, and paraplegia, will also be
discussed.

Iatropathic Injuries of Peripheral Nerves
Incidence in the United Kingdom. A growing problem:
defects in teaching; defects in training. Reasons for
delay in recognition and in treatment: error in
diagnosis; failure to understand functional significance
of the peripheral nervous system; failure to recognize
the place of operation for diagnosis, for repair, for
palliation.
The spinal accessory nerve: delay in diagnosis;
functional consequences; the significance of neuropathic
pain. The problem of the nerves of cutaneous
sensation: the particular vulnerability of the medial
cutaneous nerve of forearm, the superficial radial nerve
and the sural and the saphenous nerve. Injury to major
nerves at the hip: predisposing factors; onset; expression
of neuropathic pain; depth of lesion; the indications for,
and results of second operation. Hazards of interscalene
and other brachial plexus local blocks. The formation of
the anterior spinal artery; the contribution of radicular
vessels; their vulnerability to tamponade. The
innervation of the shoulder joint. Recommendation
towards reduction of incidence of iatropathic lesion and
towards improvement in treatment.
