“…Micro-motions are caused by instability which is difficult to eliminate in fixation systems that rely on standard interlocking nails (von Pfeil et al 2005, Dejardin et al 2006. The work of Kaspar (Kaspar et al 2005) seems to corroborate the above findings. Functional weight bearing accelerates bone healing and it strengthens newly formed callus tissue (Sarmiento et al 1977, O'Sullivan et al 1994).…”

The treatment of comminuted tibial shaft fractures in canine patients is burdened by significant risk which involves bone healing complications, such as delayed bone union. Complications may result from iatrogenic damage to blood vessels during fracture stabilization. To minimize this risk, treatment methods increasingly often rely on the concept of biological osteosynthesis. One of such methods involves the treatment of fractures with the use of new hybrid fixator consisted of an interlocking nail connected with type I external fixator. Connection of the nail with external fixator has been recently developed to maximize treatment efficiency. This manner of stabilization increases bone-fixator construct strength on forces acting in the place of fracture. It also enables fracture fixation with minimal damage of the blood supply of bone fragments. This article describes surgical procedure of stabilization of comminuted tibial bone fractures in four dogs by the use of interlocking nail connected with external fixator type I, discusses and evaluates the results of clinical treatment with the involvement of the said fixator. To control bone consolidation process the radiograms were taken in 6 and 8 week of healing.In all cases, the reviewed methods of clinical treatment were successful in producing bone union after eight week of healing. During the whole period of observations no complication was observed. In all cases the intramedullary nail were left in the medullary canal after the healing process was finished. The fixator supported quick restoration of limb function after treatment.

“…This fatigue stress to screws may cause failure or produce metal splinters on their surface. [8,25,28] In our series, we used our newly designed unreamed IM nail and allowed FWB the day after surgery. We had no implant failure even in unstable and distal tibia fractures.…”

AMAÇTibia kırıklarının cerrahi tedavisinde oymalı ve oymasız seçenekler vardır. Oymalı çivilerin biyomekanik üstün-lükleri vardır ancak endosteal dolaşıma önemli ölçüde zarar verir. Oymasız çiviler ise endosteal dolaşımı korur fakat daha az stabil bir sabitleme sağlar. Her iki sistemde de distal kilit vidası kaynaklı instabilite nedeniyle hemen tam ağırlık vermek mümkün değildir. Ayrıca, distal kilit vidası, skopi kullanma ihtiyacının ve cerrahi sürenin uzamasından sorumludur. Bu çalışmada, yeni intramedül-ler çivi ve oymasız sistemle stabil bir sabitleme sağlayıp hemen tam ağırlık vermeye izin veren distal kilit vidası sisteminin klinik sonuçları sunuldu. GEREÇ VE YÖNTEM2008 ile 2010 yılları arasında yeni intramedüller sistemle ameliyat edilmiş 50 tibia kırığı (49 hasta) geriye dönük olarak değerlendirildi. Ameliyattan hemen sonraki 1. gün tam ağırlığa izin verildi. Hastalar ameliyat sonrası en az 10 ay takip edildi. BULGULARDistal kilitleme için ortalama skopi süresi 18 saniye (min: 10, maks: 30) idi. Ortalama kaynama süresi 9 hafta (min: 6, maks: 12). Nörovasküler yaralanma, derin enfeksiyon, yanlış veya gecikmiş kaynama ve kaynamama yoktu. SONUÇBiz bu çalışmamızla yeni geliştirdiğimiz intramedüller çi-vinin ve distal kilit vidası sisteminin distal kilit vidasından kaynaklanan stabilite problemlerinin çözülmesinde bir seçenek olabileceğini gösterdik. Ayrıca sistemimiz ameliyatta gereken skopi ihtiyacını da önemli ölçüde azaltmaktadır.Anahtar Sözcükler: Distal kilit vidası; skopi; hemen tam ağırlık verme; stabilite; tibia kırığı.

“…The speed of this healing process is influenced by the magnitude and direction of the interfragmentary motion (IFM) allowed within the fracture site. Factors that are known to influence IFM include weight bearing, nail diameter, number and orientation of locking screws used, and specialised implant design features such as angular-stable locking, compression locking, and controlled axial micromotion (Brown, Bryan, & Stevens, 2007, Dailey et al, 2013, Kaspar et al, 2005. Less attention, however, has been given to the role of the fibula in tibial IFM after IM nailing.…”
