“…In order to design the polyaxial self-locking anatomical plate, the outer side of the distal tibia torsion angle must be considered [13, 14]. In this study, we found that the outer side of the distal tibia torsion angle was different from that found in previous studies [15, 16]. The torsion segment length is from where the outer side of the tibia begins to twist to the front of distal tibia's articular surface [17–19].…”

In order to provide scientific and empirical evidence for the clinical application of the polyaxial self-locking anatomical plate, 80 human tibias from healthy adults were scanned by spiral CT and their three-dimensional images were reconstructed using the surface shaded display (SSD) method. Firstly, based on the geometric data of distal tibia, a polyaxial self-locking anatomical plate for distal tibia was designed and constructed. Biomechanical tests were then performed by applying axial loading, 4-point bending, and axial torsion loading on the fracture fixation models of fresh cadaver tibias. Our results showed that variation in twisting angles of lateral tibia surface was found in various segments of the distal tibia. The polyaxial self-locking anatomical plate was constructed based on the geometry of the distal tibia. Compared to the conventional anatomical locking plate, the polyaxial self-locking anatomical plate of the distal tibia provides a better fit to the geometry of the distal tibia of the domestic population, and the insertion angle of locking screws can be regulated up to 30°. Collectively, this study assesses the geometry of the distal tibia and provides variable locking screw trajectory to improve screw-plate stability through the design of a polyaxial self-locking anatomical plate.

“…A varus malposition can be tolerated up to 25°, and recurvation is tolerable up to 20° [9]. Intramedullary nailing is the treatment of choice in cases of complicated and dislocated fractures, whereas the use of an external fixateur is an option for open and complicated fractures [5,10]. Open fractures of the lower extremity have a high incidence of non-union and infection, especially when the tibia is involved [3].…”

Salvage procedures in lower-extremity trauma in a child with hereditary motor and sensory neuropathy type I: a case report

et al. 2012

IntroductionFractures of the lower extremity are a common type of childhood injury and many can be treated without surgery. Dislocated and open fractures are an indication for fracture stabilization via either intramedullary nailing or, in the case of complicated fractures, external fixation. But if complications are likely because of diseases and disabilities (for example, a neuropathy) that can complicate the post-operative procedure and rehabilitation, what options does one have?Case presentationWe report a nine-year-old Caucasian girl who had hereditary motor and sensory neuropathy type I and who was admitted with a grade I open tibia fracture after a fall from a small height. Plain radiographs showed a dislocated tibia and fibula fracture. An open reduction with internal fixation with a compression plate osteosynthesis was performed, and soft tissue debridement combined with an external fixateur was undertaken. Three months later, she was re-admitted with localized swelling and signs of a local soft tissue infection in the middle of her tibia. Plain radiographs showed a non-union of the tibia fracture, and microbiological analysis confirmed a wound infection with cefuroxime-sensitive Staphylococcus aureus. Because of the non-union, the osteosynthesis was replaced with an Ilizarov external fixateur, and appropriate antibiotic therapy was initiated. Four months after the initial accident, the fracture was consolidated and we removed the external fixateur.ConclusionsIf there is a pre-existing neuropathy and if disease makes it difficult for a child to follow all post-operative instructions, salvage procedures should be kept in mind in case of complications. There are multiple therapeutic options, including osteosynthesis, intramedullary nailing systems, cast therapy, or an external fixateur like the Ilizarov or Taylor spatial frame system. The initial use of an external fixateur such as an Ilizarov or Taylor spatial frame in patients with pre-existing neuropathies should be kept in mind as a possible treatment option in complicated fractures, especially in a child with pre-existing neurological or endocrine pathologies.

Korrektur von sprunggelenksnahen Deformitäten mit dem Taylor Spatial Frame

Abstract: In cases of post-traumatic supramalleolar deformities with poor soft tissue and bone quality the Taylor spatial frame is a useful tool. Angular, axial, translational and rotatory deformities are corrected simultaneously without complex and time-consuming fixator reconstructions.
