Re-implantation of avulsed,
amputated thumb, fingers & foot
First successful thumb re-implantation
was performed in 1965 by Komatsu and Tamai. Since then, continuous
advances are taking place in digital re-implantations. Also
the patients demand for re-implantation of their amputated
parts, regardless of the nature of their injuries or the condition
in which fingers were transported. The surgeons must be able
to comply with this demand and provide results that will be
satisfactory in the terms of function and appearance. In avulsion
injuries of digits and thumbs, both vessels and nerves are
damaged. Usually it is not limited to the site of amputation
and on closer inspection of part, one may discover structures
dangling from its cut end. These may be tendon or nerves,
but rarely vessels. Vessels in this condition are commonly
avulsed distally. Viability in such amputated part can be
successfully restored either by bone shortening or by use
of vein grafts.
Transportation and Ischaemia time of
an amputated stump
Amputated part can be successfully
transported to micro-vascular unit by wrapping the amputated
stump in saline soaked pad or gauze. This stump should be
put in a polythene bag and this bag is put into another polythene
bag filled with ice. So the amputated stump will not come
in direct contact with ice. Stump should not be put directly
into water or saline solution to prevent maceration.
Normally
with such method, amputated digits or thumb remain viable
for more than 20hrs. (cold ischaemia time). If amputated stump
of digit is not kept in ice, even then it will remain viable
for more than 12hrs, (warm ischaemia time).
Re-implantation of thumb
The patient Mr. Dambar Rana, had crush and avulsion injury
of Rt. thumb just distal to Metacarpo-phallangeal joint. Patient
came well within warm ischaemia time carrying the amputated
stump and dangling tendons avulsed at level of distal forearm
from musculo tendinous junction. This thumb was successfully
re-implanted by doing 1.5 to 2cm shorting of bone distal to
M.P joint. In this one artery and two veins were anastomosed
without any vein graft. A single digital nerve was also successfully
anastamosed. Patient had complete functional recovery of Rt.
thumb.
Re-implantation of Foot
Mr. Shahwaz Khan, 12 yrs old child was brought from Saharanpur
with both fore feet amputated. Patient reached the hospital
8-10hrs after injury with both feet well kept in ice bags
and wrapped in saline soaked gauze. Rt. forefoot was successfully
re-implanted with all vessels, tendons and nerves repaired.
And in other limb, amputated stump of foot was covered with
a neuro sensory free flap. Patient had complete sensory and
functional recovery of Rt. foot. Now after 4 months, patient
can walk on his own feet.
