Welcome
to my website!
Here
you can find information concerning lunatomalacia (also called
Kienbock Disease)
Own
experiences with operations, conversations with doctors, and parts of the
unfortunately very less literature which is available, are subject of this
representation.
Attention:
Thank
you very much, and I hope you will be better soon.
What
is lunatomalacia?
Lunatomalacia
(Kienböck´s disease, avascular necrosis of lunate)

Definition:
Marked
by asepsis (germ-free), rarely complete, most partly existing necrosis (
) of wrist os lunatum (lunate bone), caused by reduced blood supply.
Further on this causes an increasing osteolysis and a fracture of the lunate
bone. The consequence is an arthrosis (joint disease) of the carpal bones.
Synonyms:
Kienböck’s
disease
Referring
to Robert Kienböck (1871 – 1953), roentgenologist from Wien, who was the
first person that documented this disease in 1910.
Symptoms:
Your
wrist reacts with spontaneous pain on palpation and compression, painful
swelling, loss of strength and motion. These symptoms appear slowly, in the
beginning mostly unnoticed,
Mainly
the dominating hand is afflicted with this disease. But also both wrists can be
diseased. An American statistics with 423 participants (compare left hand side)
documents 58 persons with a result on both sides
Causes:
There
are no safe perceptions concerning the exact causes.
In
discussion are:
-
permanent
microtrauma (for example: persons who work with pneumatic hammers, store-masons,
etc.)
-
accidents
which cause vascular injuries or occlusions
-
vascular
abnormities
-
a
combination of several factors mentioned above
People
concerned:
rarely
young persons, adults mainly in the age of 20 up to 40 years
Diagnosis:
As
this disease is very seldom, it is rather improbable that the doctor you
consulted will come to an appropriate conclusion immediately after he noticed
the first symptoms. Tendinous synovitis, sprain and cancer are possibilities of
false estimations. So months and years often go by until after all the correct
diagnosis, called lunatomalacia , is found. Then phases I and II of this disease,
which have a very less chance to be healed without operation, are unfortunately
passed over most of the time. But mainly the disease only then attracts
attention when phase III has already shown up.
So if you have to suffer from the above mentioned
symptoms, point your doctor to the possibility of lunatomalacia. Thereby you
probably don’t have to go to a lot of different doctors during the following
years. Don’t let them calm you down with the reference to an inconspicuous
x-ray picture. You should insist on a MRT (nuclear resonance scanning) even if
it doesn’t belong to your doctor’s budget.
Examinational
methods:
RADIOLOGICAL:
-
computerized
axial tomography (CT); special x-ray examination. A computer shows
three-dimensional sectioned pictures of special parts of your body. Especially
qualified for the discovery of bone fractures which can’t be recognised by
conventional x-ray.
You will sit
comfortably on a chair and just put your hand in the machine. It doesn’t take
more than 2 minutes.
-
nuclear
magnetic resonance(MRT, MRI, NMR): no strain caused by x-ray beams. Strong
magnetic fields produce electromagnetic waves which show results like soft
tissue changes and vitality of bones.
You lie prone and get pushed into the so called “pipe”.
But don’t be afraid, it’s not dark in there. The pipe is open at head and
feet so you can watch the proceedings in the room. Only the keeping still for 15
min is not very convenient. To protect you against the loud noise of the machine,
you will get some ear stoppers.
First they make a normal “picture”. Then they will inject a
contrast medium into the back of your hand vein. Now the second picture follows.
It depends on if and how the medium gets concentrated in the lunate bone to find
out something about the bones blood supply.
ARTHROSCOPY:
Now
and then it may happen that in spite of using highly sensitive examinational
technologies like MRT and CT you can’t commit on the exact phase of the
disease and the thereby necessary surgical procedure. Then the wrist will be
examined by arthroscope (reflected) before the actual wrist operation takes
place or even during the operation itself. The patient is in local anaesthesia
or in complete narcosis, his arm is bloodless (compare below). Now the hand will
be put up and the wrist will be spread. Two or three little cuts in the skin (less
than 1 cm) are necessary to insert the arthroscope (small 2 mm long style with
palpatory stick and optical magnifying glass at the end) into the problematical
area. The palpatory stick can also be replaced by special mechanisms like small
forceps or fraises to remove the tissue which is in the way. A connected monitor
shows all afflicted parts of the joint and enables an exact result.

Therapy:
Conservative
(phase I and II)
Fixation
of wrist with a cuff for at least 6 weeks. This method hasn’t reached any
satisfying results up to now.
Operative
(phase III and IV)
in-patient
basis: about 1 week in hospital
or
ambulatory:
Discharge
a couple of hours after operation. I think that it is a good idea to offer the
ambulant way of operation in spite of the complexibility of this surgery. Of
course this only works if you can be sure to have permanent company and help
from a closely connected person. The day of operation and the second day are
definitely hard. On the third day at the latest, when you feel better again, you
will be happy to be at home. Why staying in hospital for some additional days,
getting bored and having a lot of supplementary costs? But in the meantime there
shall also exist hospitals which let their patients go home on the fourth day at
least. This would probably be a compromise. If you have to stay over night at
another place than at home, because you live too far away, (arrival the day
before and departure the day after the operation) you should definitely book a
hotel without full board and which is not very expensive. You will either be
interested in an exclusive hotel nor in extraordinary food! This money you can
save.
ANAESTHETIC PROCEDURES:
Your
operating surgeon will try to convince you of a general anaesthesia, which is
understandable in his situation. He can work in calmness and doesn’t have to
take care of a totally nervous and frightened patient. Nevertheless I insisted
on a local anaesthetic. This was a luck, because during the operation my lunate
bone was found to be in a surprisingly good condition, in spite of being in
phase III – IV. So my doctor and I could talk to each other and we decided not
to perform the originally planned partly artificial ankylosis but to carry out a
revascularisation. Up to now we achieved an exceptional healing process.
General
anaesthesia: so
called incubative anaesthesia
ADVANTAGE:
patient doesn’t notice anything during op.; fast and safe;
DISADVANTAGE:
communication between doctor and patient during op. is not possible; immediately
after awakening you will be in severe pain
You
will get an injection into your arm pit which narcotises your arm completely.
The patient will possibly get a light sleeping medicine to lower the excitement
ADVANTAGE:
the patient can be talked to at any time; use
a Discman with your favourite CD. This calms down your nerves. Your doctor will
support this idea, if you ask him. The brachial plexus anaesthesia will
possibly last some hours longer than the general anaesthesia. This is a pleasant
feeling, because you will be in great pain after a bone surgery.
DISADVANTAGE:
you can hear any kind of noise: hammering, sawing, drilling, ......
Attention:
on your way to the operation room you should hold your arm closely, because it
will be completely numb and seems to be a dead piece of meat which doesn’t
belong to yourself! Really horrible! You will run the risk to catch an injury of
your shoulder, if your arm falls down, because the weight is really considerable.
BlOODLESSNESS:
before
the surgeon makes the first cut, your whole arm must be bloodless. Thus a good
sight on the part to be operated shall be guaranteed and the danger to
unintentionally injure surrounding parts can be decreased. The whole performance
of the operation is so to speak depending on millimetres. To make the arm
bloodless they fix a pneumatic cuff around the brachial arm. Then the arm gets
wrapped tight by using an elastic, so that the blood will be pressed into the
direction of your shoulder. When the blood has passed the cuff, the tourniquet
will be blown up so that the blood can’t flow back into your hand. This
bloodless state may take up to two hours, so that the surgeon has to be done
with those activities which require an optimal view.
-
shortening
of radial bone: thereby both bones shall be brought to an equal level (Null
Variante). There are different starting points:
overlength
of ulna compared with radial bone (Ulna-Plusvariante) and
underlength
of ulna compared with radial bone (Ulna-Minusvariante).
The
last one predominates.
shortening
of capitatum
-
so
called spongiosa-plasty: filling up the necrotic lunate bone with bone tissue of
your own body, for example taken out of your iliac crest, which is the biggest
reservoir with the best bone forming (osteogenous) potency. Also spongiosa of
the pea shaped wrist bone (os pisiforme, no. 8 of picture above) or other wrist
bones are used.
-
insertion
of a blood conveying artery into the lunate bone.
Different
kinds of wrist bones are connected with screws to achieve a pain-free exertion,
for example STT-arthrodesis (the first letters of the related bones are used).
Also other wrist bone connections are thinkable. If necessary, the lunate bone
will be removed, too. After that limited bendings and turnings of the wrist are
still possible. The fingers are completely movable.
Last
solution, if nothing else helps. Complete stiffing of the wrist. Bending of
wrist not possible any more. Turning of wrist still possible. Fingers completely
movable.
The
lunate bone is removed and replaced by an implant (titanium, plastics or
unnecessary muscle tendons of your hand). Often noticed displacements (luxations)
and/or damages of the implants pointed out that this method does not correspond
with the knowledge of science any more.
To
achieve decompression, several wrist bones are removed and the rest of them will
be screwed with each other. Mobility is possible compared to the partly
arthrodesis mentioned above.
In
all phases of lunatomalacia a partly or complete enervation of the wrist can be
carried out. Also just one of these methods or enervation as an additional
operation are possible. Thus different nerve branches, which are sensitively
supplying the wrist, will be cut. By this they want to achieve that patients
won’t be in great pain any more in future.
Attention: This has nothing to do
with the mobility of your fingers, which is further on 100% guaranteed, as the
muscle tendons are not concerned!!!

Motion
therapy with a physical therapist who has experience (very important) with hand
operations!
-
If
you are in pain after exertion (of course only if you got rid of the plaster and
the threads), I recommend you to take short baths in ice-cold water which you
should fill in a tall pot. (Fill the water in there and put it into the
deep-freeze chest!)
Prognosis
This
disease is unfortunately not curable.
Any
operation which is necessary within phase III can, if being successful, reduce
or take away pain. But also a successful operation and a healing process over
years, which is almost free of afflictions, won’t guarantee that there won’t
show up a worsening of your wrist, which probably makes another op. necessary.
The rather less statistics of illness which exist are showing the whole spectrum
of possible healing processes, beginning with very bad up to very good.
Therefore no predictions can be ensured. With regard to the reduction of pain,
power, maintenance of mobility and the quality of life after operation,
the achieved results are mostly at least satisfactory!!!
Personal
remarks
It
will be a shock, if you are holding the depressing diagnosis of lunatomalacia in
your hands, that’s for sure. Life will change a lot in most cases: different
sportive activities and hobbies have to be cancelled from one day to the other.
Special wishes concerning your profession suddenly can’t be realised any more.
Many concerned people can’t go on practicing their profession, they have to
retrain or get unemployed.
Nevertheless:
My
doctor told me:
“The
worst you can do now is to be sorry for yourself and carry your ill hand around
like a dead part of your body which doesn’t belong to you.
He
is right!
Keep
all your courage and power! Have patience --- and take your fate tightly in both
of your hands (yes, it works!!!)
GOOD
LUCK!!!
