Summary. Femoral fractures are common problem in Orthopaedic Traumatology.
Preservation of intramedular and periosteal vascularisation is very important
in the surgical treatment of these fractures. It is shown new internal
fixa-tor that provides fixation while application can be performed by minimally
invasive method with no contact between the implant and bone fragment in
fracture area. The device is selfdynamisible. It has been applied to 38
patients. In the beginning application has been performed using open method
on the fracture area, while later, after author has developed new, selfnavigatible
reduction device, application of internal fixator has been performed by
minimally inva-sive surgery, after closed reduction has been achieved.
Follow up was 2.1 year (4 months to 3.5 years). Bone healing was achieved
in all patients within 3.6 months (3-5 months) with big amount of periosteal
callus formation equally distributed around the fracture area. Self-dynamisation
of the implant has been proven radiologicaly. There was no any complication
in all patients treated.
Key words: Femur, Fracture, internal fixation, reduction device,

NOVA BIOLOŠKA METODA UNUTRAŠNJE FIKSACIJE
FEMURA
Kratak sadržaj: Prelomi femura su čest ortopedsko-traumatološki
problem. Očuvanje intramedularne i perisostalne vaskularizacije igra vrlo
važnu ulogu u lečenju svakog preloma duge kosti a naročito femura. U ovom
radu, prikaziju se rezultati primene jedne nove, originalne metode kojom
se postižu ciljevi očuvanja oba pomenuta vaskularna sistema duge kosti,
što nije moguće ostvariti drugim metodama. Novi implantat je u zoni preloma
odvojen od kosti, ne dolazeći u koliziju sa vaskularnim strukturama kosti,
a istovremeno je i samodinamizirajući čime se ostvaruju optimalni biomehanički
uslovi za zarastanje preloma. Do sada je primenjen na 38 pacijenata. U
početku aplikacija novog implantata je bila ostvarivana otvorenim putem
tj. otvaranjem mesta preloma a sada se izvodi minimalnom hirurškom intervencijom,
kroz dva mala reza van mesta preloma. Prethodna repozicija preloma se ostvaruje
pomoću samonavigacionog uredjaja za repoziciju kosti koga je takodje konstruisao
autor. Dužina praćenja bolesnika posle operacije je u proseku 2,1 godinu
(od 4 meseca do 3,5 godine). Do zarastanja je došlo kod svih pacijenata
u proseku u roku od 3,6 meseci (3-5 meseci) us stvaranje velike količine
periostalnog kalusa ujednačeno rasporedjenog celom cirkumferencijom oko
preloma. Samodinamizirajući efekat je dokazan radiološki. Nije bilo ni
jedne komplikacije.
