Abstract

Objective: The aim of this study was to investigate the effect of orthosis on tibiofemoral angle in infantile tibia vara. Method: A total of 14 subjects (9 male and 5 female) aged between 23-32 months were included in the study. The tibio femoral angles of the individuals were evaluated with universal goniometer before and 3 months after orthesis. Results and Conclusion: The mean tibiofemoral angle before orthosis was 14,36 ± 5,20 degrees in the subjects. The mean tibiofemoral angle after orthosis was 7.28 ± 2.68 degrees. It was determined that tibiofemoral angle decreased significantly after bracing (p<0.05). Bracing in infantile tibia patients may help reduce tibiofemoral angle in the early period. In the future; with larger sampling, control group and long-term follow-up studies can be planned.

Abstract

Amaç: Çalışmanın amacı infantil tibia vara’da ortezlemenin erken dönemde tibiofemoral açı üzerine etkisini incelemektir. Yöntem: Çalışmaya yaşları 23-32 ay arasında, 9’u kız, 5’i erkek toplam 14 birey alındı. Bireylerin tibio femoral açıları universal gonyometre ile ortezleme öncesi ve ortezlemeden 3 ay sonra değerlendirildi. Bulgular ve Sonuç: Ortezleme öncesi bireylerin tibiofemoral açı ortalaması 14,36 ± 5,20 derece olarak ölçüldü. Ortezleme sonrası tibiofemoral açı ortalaması ise 7,28 ± 2,68 derece olarak belirlendi. Ortezleme sonrası tibiofemoral açının ortezleme öncesine göre anlamlı derecede azaldığı tespit edildi (p<0,05). İnfantil tibia vara’lı bireylerde ortezleme erken dönemde tibiofemoral açıyı azaltmada etkili olabilir. Gelecekte; daha büyük örnekleme sahip, kontrol grubunun dahil edildiği ve uzun dönem takipli çalışmalar planlanabilir.
