Abstract

Objectives: We evaluated the effects of radial shortening osteotomy on the radiolunate joint load distribution. Materials and methods: This biomechanical study used standard left wrist models made of solid foam (Sawbones®, Malmö, Sweden). The radioulnocarpal joint load distribution was investigated in the normal wrist model and 2 mm and 4 mm radial shortening osteotomy models under 14 kgf and 25 kgf loads when the wrist position was neutral. Results: In the normal wrist group, the comparison of the average pressure distributions under the 14 kgf and 25 kgf loads shows that the increase at the ulnocarpal joint loading and the decrease at the radiolunate joint loading were statistically significant (p=0.012, p=0.036, respectively). When we compared the respective average pressure distributions after 14 kgf and 25 kgf loading, there were no significant differences between the normal wrist and the osteotomy groups. Conclusion: Consequently, radial shortening osteotomy is not effective in decreasing radiolunate joint loading when the wrist is in neutral position.

Özet

Amaç: Radyal kısaltma osteotomisinin, radiolunat eklem yük dağılımı üzerindeki etkileri araştırıldı. Gereç ve yöntemler: Bu biyomekanik çalışmada, sert köpükten imal edilmiş sol el bileği modelleri kullanıldı (Sawbones®, Malmö, Sweden). Radioulnokarpal eklem yük dağılımları, sağlam el bileği modellerinde ve 2 mm ve 4 mm radyal kısaltma osteotomisi modellerinde, 14 kgf ve 25 kgf yüklenmeler altında el bileği nötral pozisyonunda iken, araştırıldı. Bulgular: Sağlam el bileği modellerinde, 14 kgf ve 25 kgf yüklenme altında oluşan ortalama basınç dağılımları karşılaştırıldığında, ulnokarpal eklemdeki artış ve radiolunat eklemdeki azalma istatistiksel olarak anlamlı bulundu (sırasıyla, p=0.012, p=0.036). 14 kgf ve 25 kgf yüklenme sonrası oluşan ilgili ortalama basınç dağılımları karşılaştırıldığında, sağlam el bileği ve osteotomi grubu arasında anlamlı fark saptanmadı. Sonuç: Sonuç olarak, radyal kısaltma osteotomisi, el bileği nötral pozisyonunda, radiolunat ekleme binen yükleri azaltmada etkili değildir.
