Fracture treatment has experienced a fascinating evolution in the last years. The aim of this chapter is to reveal some clinical and biomechanical studies regarding innovative implants. After a short introduction (1), we intend to present our results regarding (2) dynamic condylar screw versus condylar blade plate in complex supracondylar femoral fractures; (3) biomechanical analysis of four types of implants in humeral fractures; (4) clinical and experimental studies for optimal stabilization of trochanteric fractures: the gliding nail; (5) intramedullary XS nail for pilon and ankle fractures: design, biomechanics, and clinical results; (6) the XS nail for the treatment of patella and olecranon fractures; and (7) plates with polyaxial stability for fractures of distal radius and proximal humerus. In conclusion, the authors highlight the advantages of these innovative implants in difficult trauma cases. Biomechanics 2 DCS versus CBP in complex supracondylar femoral fractures: a biomechanical studyDistal femoral fractures represent a challenge for orthopedic surgeons, and despite numerous biomechanical studies, the optimal implant is still controversial [1][2][3][4]. However, while plates with angular stability and retrograde interlocking nails are nowadays the best choice for treatment, CBP and DCS were the most used implants until the development of these innovative implants [5].In a biomechanical study from 2009, the authors compared the mechanical rigidity of the bone/implant (DCS or CBP) construct in complex supracondylar femoral fractures [5,6].Twelve synthetic composite femoral bones were fixed in the distal part with six DCS and six CBP, and then, the authors performed by osteotomy a bone defect of 1.5 cm to simulate a complex supracondylar fracture type A3/AO (Figure 1).The femurs were sectioned in the midshaft, and the proximal part of the distal fragments was fixed in a metallic adapter sleeve. The bone-implant constructs were tested for seven types of loading: (1) internal compression; (2) external compression; (3) anterior compression; (4) posterior compression; (5) axial compression; (6) external torsion; and (7) internal torsion.The compression tests were realized up to 350 N, and the applied torsion attended 25 Nm. The tests were repeated six times in order to establish the statistic dispersion. All the measurements for DCS were realized with or without compaction screw.The compression force and loading force were measured by a M221B04 (PCB Piezotronics force transducer), while linear deformation values for the compression were measured using two inductive transducers applied in frontal axis (TD1) and sagittal axis (TD2) (Figure 2). Data acquisition was realized by a six-channel admittance bridge, an interface board, and a digital data acquisition system DAQ1200 connected to a laptop.According to study measurements, by reporting the loading/unloading force to the transducer (TD1 and TD2) displacement, we represented hysteresis cycles as diagrams for the femur/DCS (with and without compaction screw)...

“…The XS nail ® (Intraplant ® ) for the treatment of malleolar fractures has a round profile and a diameter of 4.5 mm (Figure 1), or 3.5 mm for the XXS(L) nail [9,10]. Depending on the fracture to be treated, the XS nail is available with four to eleven locking holes with 9-mm spacing, with the two holes closest to the fixation having a longitudinal oval alignment.…”

“…• In osteoporotic bones, better stabilization using threaded wire and nail fixation than by using smallfragment screws. • Procedure protects soft tissue by using intramedullary positioning of the implant[1]. • Soft-tissue management of local complications made easier by intraosseous positioning of the implant.…”

In the period from 05/2000 to 01/2002, 194 ankle fractures were treated with the IP-XS-Nail((R)). Follow-up examinations were conducted on 162 patients with an average age of 51.2 years after an average of 15 months. 62 Weber B fractures (38.3%) and 45 Weber C fractures (27.7%) were evaluated. There were bimalleolar fractures in 55 cases (34.0%). According to the Olerud Score (clinical and radiologic score), 95 patients (58.6%) had an excellent, 54 (33.3%) a good, nine (5.5%) a moderate, and four (2.4%) an unsatisfactory result.
