Abstract
Nerve impairment in the hand probably constitutes its major disability.
The functional outcome after nerve repair is determined by numerous
factors. As rule in all cases of never injury, the nerve must be repaired as
soon as it is diagnosed and should not be unduly delayed, but done alone
may result in frustrating outcome.
Tendon transfers follow a basic concept that nothing new is created but
functional parts are rearranged into the best possible working
combination i.e. involve redistribution, not creation, of new power units.
These involve detachment of the tendon distally, careful mobilization and
rerouting it to a new distal attachment.
The aim of this thesis is to give a general idea about the most common
methods for tendon transfers done for the various peripheral nerve
injuries of the upper limb and its effect on the patient.
This study included 10 patients with different nerve injuries of the upper
limb. The median nerve was injured in 2 patients, the ulnar nerve in 3
patients, and the radial nerve in 4 patients. One patient had a combined
low median and ulnar nerve injury. Tendon transfer was done, after
more than six months of the nerve injury and epineural repair in 8
patients. In the two remaining patients, who had posterior interosseous
nerve injury in the proximal third of the dorsum of the forearm, tendon
transfer was done after 4 months of the injury.
In general, early tendon transfer acts as a temporary substitute for the
paralyzed muscle until reinnervation occurs; so it acts as an internal
splint. If reinnervation is suboptimal, early tendon transfer acts as a
helper to augment the power of the muscle. If reinnervation fails to occur,
the tendon transfer acts then as a permanent substitute.
Key words; median nerve injury, ulnar nerve injury, radial nerve injury,
combined nerve injury, tendon transfer.
