Abstract

Objectives: This study aims is to investigate mechanicalproperties of intramedullary (IM) nailing and anatomicallocking plate in a bone model based on the hypothesis thattheir combined usage increases safety of fixation stabilization. Materials and methods: Twenty-one left distal femoralfracture models were used in the study. Bones were divided intothree equal groups. Group 1 specimens were fixed laterally bydistal femoral anatomical locking plate. Group 2 specimens werefixed with retrograde distal femoral IM nail. Group 3 specimenswere fixed with both distal femoral anatomical locking plateand retrograde distal femoral IM nail. In mechanical tests,alterations in axial loading, torsion angles, and load to failurevalues were measured and compared between groups. Results: Compared to group 1, group 2 was relativelymore resistant in axial load tests (p=0.225), andsignificantly more resistant in load to failure tests(p=0.048). Group 1 was relatively more resistant intorsional load tests (p=0.949) compared to group 2.Group 3 was significantly more resistant than group 1in axial (p=0.001), torsional (p=0.012) load tests andload to failure tests (p=0.008). Group 3 was significantlymore resistant compared to group 2 in axial (p=0.003),torsional (p=0.008) load tests, and relatively more resistant(p=0.059) in load to failure tests. Conclusion: Thanks to its high mechanical strength andearly mobilization capability, distal femoral anatomicallocking plate and IM nail combination might be a choiceof treatment in complicated osteoporotic or distal femoralfractures from high-energy trauma in young adults.

Özet

Amaç: Bu çalışmada, kombine kullanımlarının tespitstabilizasyonunun güvenliğini artırdığı hipotezinden yolaçıkılarak intramedüller (İM) çivi ve anatomik kilitli plağınmekanik özellikleri bir kemik modelinde araştırıldı. Gereç ve yöntemler: Çalışmada 21 sol distal femur kırığımodeli kullanıldı. Kemikler 3 eşit gruba ayrıldı. Grup 1örnekleri distal femur anatomik kilitli plak ile yandan tespitedildi. Grup 2 örnekleri distal femur retrograd İM çivi iletespit edildi. Grup 3 örnekleri hem distal femur anatomikkilitli plak hem distal femur retrograd İM çivi ile tespit edildi.Mekanik testlerde aksiyel yüklenme değişimleri, torsiyonaçıları ve kırılmaya kadar yüklenme değerleri ölçülerekgruplar arası karşılaştırıldı. Bulgular: Grup 1e göre grup 2 aksiyel yüklenme testlerindegöreceli olarak daha dayanıklı (p=0.225), kırılmaya kadaryüklenme testlerinde anlamlı şekilde daha dayanıklı (p=0.048)idi. Torsiyonel yüklenme testlerinde grup 1 grup 2yegöre göreceli olarak daha dayanıklı (p=0.949) idi. Aksiyel(p=0.001), torsiyonel (p=0.012) yüklenme testleri ve kırılmayakadar yüklenme testlerinde grup 3 grup 1den anlamlı şekildedaha dayanıklı idi (p=0.008). Grup 2ye göre grup 3 aksiyel(p=0.003), torsiyonel (p=0.008) yüklenme testlerinde anlamlıolarak, kırılmaya kadar yüklenme testlerinde (p=0.059)göreceli olarak daha dayanıklı idi. Sonuç: Yüksek mekanik kuvveti ve erken mobilizasyonimkanı ile distal femur anatomik kilitli plak ve İM çivikombinasyonu karmaşık osteoporotik veya genç erişkinlerdeyüksek enerjili travma kaynaklı distal femur kırıklarındatercih edilen bir tedavi olabilir.
