Abstract

Aim: In this
study; We aimed to evaluate the outcomes of distraction cases with distraction
osteogenesis technique using monolateral and annular external fixator in
patients who suffer from lower extremity shortness.

Patients and
Methods: In our study, we tried to explain the results of the lower extremity
osteotomy operations using  distraction
osteogenesis technique in the 16 lower extremities of 12 patients. Seven of the
patients were female and 5 of them were male. The mean age of the patients was
11.8 (4-26) years. Four of the patients' femurs, 4 of the patients' tibias, and
4 of the patients' both femurs and tibias were extended. A monolateral external
fixator (orthoFix) was used in the distraction of 15 patients, and Ilizarov's
ringed external fixator was used in the extension of one patient.

Results: The average
length of extension was 3.5 cm (2-7), the waiting period before extension was
13.2 days (9-20), the healing index was approximately 52 (31-90), the ratio of
gained lenght to the extended bone segment was approximately 13,6%
(5%-19%)  and the average duration of
stay of fixators was 182 days (140-270). Twenty complications were observed in
the 16 lower extremity lengthening procedures. The most common complication (in
9 patients) was angulation.

Conclusion: In the
extensions depending one Ilizarov's extension principles, the extensions are
successful;but  it should not be forgotten
that the number of complications might be excessive and operation experience is
also important.

Alt Ekstremite Uzatma Osteotomilerinin Klinik Sonuçları

Abstract

Amaç : Çalışmamızda; alt eksremite
kısalığı olan hastalarda, monolateral ve halkalı eksternal fiksatör
kullanılarak, distraksion osteogenezi tekniği ile yaptığımız uzatma
olgularımızın sonuçlarını değerlendirmeyi amaçladık.

Hastalar ve Yöntem: Çalışmamızda; 12 hastanın 16 alt
ekstremitesinde distraksion osteogenezi tekniği ile yapılan alt eksremite
uzatma osteotomilerinin sonuçlarını açıklamaya çalıştık. Hastaların 7'i kadın,
5'i erkek di. Ortalama yaş 11,8(4-26) dı. Hastaların 4'ünin femuru, 4'ünün
tibiası ve 4 hastanın da hem femuru hem de tibiası uzatılmıştır. 15 hastanın
uzatmasında monolateral eksternal fiksatör(orthofix), bir hastanın
uzatmasında  İlizarov'un halkalı
eksternal fiksatörü kullanıldı.

Bulgular: Ortalama uzama miktarı 3,5 cm(2-7),
uzatma öncesi bekleme süresi ortalama 13,2 gün(9-20), iyileşme indeksi ortalama
52(31-90), kazanılan uzunluğun uzatılan kemik segmentine oranı ortalama
%13,6(%5-%19), fiksatörlerin kalış süresi ortalama 182 gün(140-270)dür. Yapılan
16 alt ekstremite uzatma isleminde  20
komplikasyon görüldü. En sık görülen komplikasyon (9 hastada) Açılanmadır.

Sonuç: İlizarov'un uzatma prensiplerine
bağlı olarak yapılan uzatmalarda ,uzatmalar başarılı şekilde gerçekleşmektedir;
ancak komplikasyon sayısının fazla olabileceği ve operasyon deneyimin önemli
olduğu unutulmamalıdır.
