POSTER ABSTRACTS - ISAKOS

They were submitted to the Shock Wave therapy in
doctor's office, with an only application of 4000
impulses, with high energy (E9), after local
anesthesia.
After the application, the patients remained
immobilized with a cast per 8 weeks (the first one)
and 6 weeks (the second one) being evaluated in 4
weeks, 6 weeks, 8 weeks with and 13 X-rays
control.
Results:
To the end of 8 weeks after the application and
use of the cast glove, the patient of the
Scaphoid´s non-union presented formation of
bone bridge enters the fragments in the control x-
rays and remission of the painful symptoms.
To the end of 13 weeks the simple x-rays
evidenced consolidation of the bone fail line.
In the patient with non-union of the base of the
fifth metatarsus we removed the synthetic plaster
boot with 43 days when presented in the x-rays
control consolidation of the fracture line.
Conclusion:
The Extra corporeal Shockwave Therapy must be
considered as alternative in the treatment of
Scaphoid´s and the fifth Metatarsus’s non-union.
It presents as advantages not to be invasive, not
to present significant complications beyond lesser
operational costs; being prevented on the other
hand, the significant potential risks described in
literature, of the traditional surgical procedures.

Cementing Techniques in Total Knee
Replacement

There is a large deficit of evidence in the modern
literature upon cementing techniques in the
procedure of Total Knee Replacement compared
to that published for Total Hip Replacement and
there is no recognised ` best` or standardised
technique.
We set out to investigate the most common
techniques in modern practise in the UK today by
modern laboratory based research. Variables
included cement preparation, cement application
and temperature. Our aim was to see if there was
any measureable differences between the
techniques with special regard to the cement
pressurisation and strength of fixation in order to
define a standardised technique.
In our study we have used Tibial saw bones,
electronic pressure transducers, and industrial
standard stress rigs to evaluate the pressures that
each technique generates and the strength of
prosthesis fixation that is acheived for a variety of
cements at a spectrum of temperatures

Although minimizing blood loss in TKA, the use of
tourniquet is controversial due to the risk of
pulmonary thromboembolism. In this study, we
compared blood loss in relation to use tourniquet
during TKA.
This study was
retrospective study of 62 patients receiving
cemented or hybrid TKA ( NexGen, Zimmer). In
the T group, 25 patients received TKA with
tourniquet after synovectomy. In the LT group, 18
patients had surgery with tourniquet after
osteotomy. In the NT group, 19 patients had
surgery without tourniquet. ConstaVac blood
conservation system II (CBC II, Stryker) was used
in all cases after surgery. Intraoperative and
postoperative blood loss, decreased Hb, and the
effect of CBC II were investigated.
Mean intraoperative blood loss was
141ml in the T group, 414ml in the LT group, and
409ml in the NT group. There was a significant
difference between T and LT, NT groups. Mean
postoperative blood loss was no difference in
each group (T:412ml, LT:519ml, NT:672ml). Total
blood loss was significantly less in T group.
However, ther was no difference in the decrease in
Hb among each group (T:3.8, LT:3.9, NT:3.8g/dl).
Postoperative autotransfusion was performed in
17 of 25 cases in the T group (mean reinfusion:
303ml), 14 of 18 cases in the LT group (354ml),
and all of 19 cases in the NT group (393ml).
Allogenic blood transfusion was necessary in 3
