Abstract

Aim: In this study we aimed to analyze the relationships
between patient and treatment related factors and healing time, alignment, LEFS
score by evaluating the results of patients whom were treated with MIPO for
extra-articular tibial fractures.

Material and Method: Thirty-three
patients with extra-articular tibial fractures that were treated with MIPO
between October 2010- April 2014 in our clinic were included in the study.
Patient related factors and surgical technique details were compared with functional,
clinical and radiological results.

Results: Mean
age of 33 patients was 46.1 (20-70). 12.1% of fractures was proximal, 33.3% was
diaphyseal, 54.5% was distal; 4 (12.1%) of them were type 1 open, 4 (12.1%)
were type 2 open, remaining 25 (75.8%) were closed fractures. All fractures
were healed an average of 21.2 weeks. Comminuted fractures which are result of
direct trauma frequently healed later. Also fractures of six patients with
complications healed within longer union times. There were 3 (9.1%) patients
with more than 5 degrees malalignment at the beginning and 4 (12.1%) at 12th
month. Patients’ functional status which were evaluated with LEFS score showed 4.72
decrease at an average but this much is clinically not significant. Plate span
ratio was not correlated with union time, malalignment and change in LEFS score.

Conclusion: MIPO
method allows rapid functional healing especially in comminuted fractures and
metaphyseal region fractures with relative stability and advantages of
biologically healing. With torsional and angular stability MIPO is a good
treatment option in simple fractures of diaphyseal region. this study we aimed to analyze the relationships
between patient factors, treatment factors and healing time, alignment, LEFS
score by evaluating the results of patients whom were treated with MIPO for
extra-articular tibial fractures.

Material
and Method: In
our study pre-operative patient factors and functional scores of 33 patients
whose extra-articular tibial fractures were treated with MIPO between October
2010- April 2014 and intra-operative surgical technique factors were checked
against functional, clinical and radiological results. Results were
statistically compared.

Results: Mean age of 33 patients was 46.1 (20-70). 12.1% of
fracture was proximal, 33.3% was diaphyseal, 54.5% was distal tibial fracture;
4 (12.1%) of them were type 1 open, 4 (12.1%) were type 2 open, other 25
(75.8%) were closed fractures. All fractures healed within a mean of 21.2 weeks
union time. Comminuted fractures which occur with direct trauma more frequently
healed within longer union times. Fractures of six patients with complication
healed within longer union times. There were 3 (9.1%) patients with more than 5
degrees malalignment at the beginning and 4 (12.1%) at 12th month. Patients’
functional status were evaluated with LEFS score and 4.72 point drop in mean is
clinically not important. Plate span ratio is not related with union time,
alignment and change in LEFS score.

Conclusion:
MIPO
method allows rapid functional healing especially in comminuted fractures and
metaphyseal region fractures with relative stability and biologically union.
MIPO is a good treatment option with torsional and angular stability in simple
fractures of diaphyseal region.

Eklem Dışı Tibia Kırıkları Tedavisinde Minimal İnvaziv Plak Osteosentez Uygulama Sonuçlarını Etkileyen Faktörler

Abstract

Amaç: Bu
çalışmada eklem dışı tibia kırıkları minimal invaziv plak osteosentezi (MİPO)
ile tedavi edilen hastalar değerlendirilerek hasta ve tedavi yöntemine ait
çeşitli faktörlerin; fonksiyonel, klinik ve radyografik sonuçlara olan
etkisinin araştırılması amaçlanmıştır.

Gereç ve Yöntemler: Ekim
2010 – Nisan 2014 tarihleri arasında eklem dışı tibia kırıkları MİPO tekniği
ile tedavi edilen 33 hasta değerlendirildi. Ameliyat öncesi hasta faktörleri,
fonksiyonel skor ve ameliyat esnasındaki cerrahi teknikle ilgili faktörler ile
fonksiyonel skor, klinik ve radyolojik sonuçlar ile kıyaslandı.

Bulgular: Ortalama
yaş 46,1 (20-70) idi. Kırıkların %12,1’i proksimalde, %33,3’ü diafizde, 18
(%54,5)’i distalde oluşmuştu. Kırıkların 4 (%12,1)’i tip 1 açık, 4 (%12,1)’i
tip 2 açık, diğer 25 (%75,8) kırık ise kapalı kırıktı. Tüm hastaların kırıkları
ortalama 21,2 haftada kaynadı. Direkt travma sonucu daha sık görülen parçalı
kırıkların daha geç kaynadığı tespit edildi. Komplikasyon gelişen altı hastanın
kırığı daha geç kaynadı. Dizilim bozukluğu 5 dereceden fazla olan hasta sayısı
ameliyat sonrası 3 (%9,1) iken, 12. ayda 4 (%12,1) olarak tespit edildi.
Fonksiyonel durumları LEFS skoru ile değerlendirilen hastaların LEFS skorundaki
ortalama 4,72 puanlık düşüşü klinik olarak anlamlı değildi. Plak kırık uzunluk
oranının; kaynama süresi, dizilim ve LEFS skorundaki değişimle ilişkisi
olmadığı görüldü.

Sonuç: MİPO
yöntemi özellikle parçalı kırıklarda ve metafizer bölge kırıklarında göreceli
stabilite ve biyolojik kaynamanın avantajları ile hızlı kaynama sağlayarak
fonksiyonel iyileşmeyi sağlamaktadır. Diafizer bölgenin basit kırıklarında
açısal ve torsiyonel stabil fiksasyon sağlaması sebebi ile MİPO alternatif bir
tedavi yöntemidir.
