Abstract

Amaç: Parçalı tibia kırıklarınnın
tedavisinde kullanılan intramedüller çivinin kilitleme vidalarında deformasyon
sıklıkla görülmektedir. Bu çalışmanın amacı tibia intramedüller çivileme
sisteminde beş farklı proksimal kilitleme vidasının bükülme dirençlerini
karşılaştırmaktır.

Metod: 50 adet vida üç farklı
çapta(4.5 mm, 5 mm ,5.5 mm) ve 2 farklı yiv şeklinde( yivli ve yivsiz)olacak
şekilde beş farklı gruba ayrıldı. 34 mm iç çapa sahip bir paslanmaz çelik tüp tibiayı
temsil etmek üzere hazırlandı. Tüm vidalara uygulama sonrası üç nokta bükülme
testi yapıldı.

Sonuçlar: Yivsiz 4.5 mm ve yivli 5mm
vida gruplarının ortalama değerleri yivsiz 5 mm, yivli 5.5 mm ve yivsiz 5.5 mm
gruplarına gore anlamlı derecede düşük bulundu(p=0.000)


























Çıkarımlar: Proksimal kilitleme vidasının
deformasyonundan kaçınmak için yivsiz 4.5 mm ve yivli 5 mm vidaların
kullanılması uygun olmayabilir. Yivsiz 5 mm, yivli 5.5 mm ve yivsiz 5.5 mm
vidaların güvenli bir şekilde kullanılması önerilebilir.

Comparison of the Resistance of Proximal Locking Screws in Tibia Nailing System – A Biomechanical Study

Year 2018, Volume: 25 Issue: 1, 19 - 25, 01.03.2018

Abstract

Purpose:  Locking screw deformation is common in nailing
of comminuted tibia fractures.  The aim
is to compare five different proximal locking screws bending resistance in
tibia nailing system.

Methods: 50 screws were divided into
five groups. A stainless steel tube which has a 34 mm internal diameter was
prepared representing the proximal tibia. A 3-point bending tests were
performed on locking  screws for
determining their yield points with 3 different dimensions (4.5 mm, 5 mm and
5,5 mm) and with 2 different screw 
thread (low threaded and unthreaded).

Results: The mean yield point values
of smooth 4.5 mm and threaded 5 mm low locking screws were statistically
significant less than that of smooth 5 mm, low threaded 5.5 mm and smooth 5.5
mm,(P=0.000).


























Conclusions:  To avoid proximal locking screw deformation,
use of smooth 4,5 mm and low threaded 5 mm locking screws should be avoided in
nailing of comminuted   tibia fractures
of unreliable persons.  Smooth 5 mm, low threaded
5.5 mm and smooth screws 5.5 mm may be used safely.
