AbstractAccurate evaluation, diagnosis, and management of mandibular fractures is essential to effectively restore an individual's facial esthetics and function. Understanding of surgical anatomy, fracture fixation principles, and the nuances of specific fractures with respect to various patient populations can aid in adequately avoiding complications such as malocclusion, non-union, paresthesia, and revision procedures. This article reviews comprehensive mandibular fracture assessment, mandibular surgical anatomy, fracture fixation principles, management considerations, and commonly encountered complications. In addition, this article reviews emerging literature examining 3-dimensional printing and intraoperative imaging.

This chapter summarizes the treatment options for different fractures of the mandible with emphasis on early mobilization and restitution of form and function. Emphasis in the management of mandibular fractures includes the establishment of the premorbid occlusion, surgical anatomy, the course of the inferior alveolar nerve, and biomechanics of the mandible. The principles of plating and the concepts of load-sharing and load-bearing osteosynthesis have also been discussed so that the reader will better understand the application of each in different fracture situations. The chapter concludes by briefly describing the complications of mandible fractures and their management.

Background: Fractures of the mandible can be studied and described in anatomic terms, functional considerations, treatment strategies, and outcome measures. The performance of any fixation system depends on multiple factors including plate adaptation, screw placement, bone quality, drilling conditions, and postoperative patient compliance. Bite force assesses masticatory muscle function under clinical and experimental conditions. Method: 30 patients with isolated, noncomminuted mandibular fractures were randomly divided into two equal groups. Group 1 patients were treated using 3-dimensional locking miniplates and group 2 patients were treated with standard miniplates. The bite forces were recorded at definite time intervals: preoperatively, and second week, sixth week, third month, and sixth month postoperatively. Result: At 6 weeks postoperative, 3 month postoperative, and 6 month postoperative, the mean bite force was found to be significantly higher among group 1 patients as compared to those in group 2 in all the sites. While at 2 week postoperative, the mean bite force was found to be significantly higher in Group 2 as compared to Group 1 at incisor region. Conclusion: The overall results of the present study show better performance in bite force for the 3-dimensional locking miniplate when compared with standard miniplates.

Background —The myocardium is unable to regenerate because cardiomyocytes cannot replicate after injury. The heart is therefore an attractive target for tissue engineering to replace infarcted myocardium and enhance cardiac function. We tested the feasibility of bioengineering cardiac tissue within novel 3-dimensional (3D) scaffolds. Methods and Results —We isolated and grew fetal cardiac cells within 3D porous alginate scaffolds. The cell constructs were cultured for 4 days to evaluate viability and morphology before implantation. Light microscopy revealed that within 2 to 3 days in culture, the dissociated cardiac cells form distinctive, multicellular contracting aggregates within the scaffold pores. Seven days after myocardial infarction, rats were randomized to biograft implantation (n=6) or sham-operation (n=6) into the myocardial scar. Echocardiography study was performed before and 65±5 days after implantation to assess left ventricular (LV) remodeling and function. Hearts were harvested 9 weeks after implantation. Visual examination of the biograft revealed intensive neovascularization from the neighboring coronary network. Histological examination revealed the presence of myofibers embedded in collagen fibers and a large number of blood vessels. The specimens showed almost complete disappearance of the scaffold and good integration into the host. Although control animals developed significant LV dilatation accompanied by progressive deterioration in LV contractility, in the biograft-treated rats, attenuation of LV dilatation and no change in LV contractility were observed. Conclusions —Alginate scaffolds provide a conducive environment to facilitate the 3D culturing of cardiac cells. After implantation into the infarcted myocardium, the biografts stimulated intense neovascularization and attenuated LV dilatation and failure in experimental rats compared with controls. This strategy can be used for regeneration and healing of the infarcted myocardium.

Chapter 27 discusses fracture fixation. Although many fractures are managed nonoperatively, others require various forms of surgical intervention. Fracture fixation can be conservative or surgical. The goal is to stabilize the fractured bone, enable fast healing, and return early mobility and function of the injured extremity. Orthopedic hardware permits stabilization of the fractured bone, expediting healing and early mobility. Percutaneous pins and wires can be used to apply traction to a fracture. External and internal fixation are used when more advanced operative intervention is required and encompass external fixator devices, pins/wires, screws, plates, and intramedullary nails/rods. Hardware is unfortunately susceptible to complication, including loosening, migration, fracture, and infection.

The results of treatment in 50 consecutive patients with established non-union of the scaphoid are presented. All patients were treated under the care of a single consultant, for the same indications. Russe bone graft is compared with wedge bone graft plus Herbert screw fixation, in terms of union and function. Overall, a higher success rate was obtained by wedge graft plus Herbert screw, and a significantly better range of movement. However, Russe bone graft appears equally satisfactory for fibrous non-union.
