PURPOSE: Views on treatment procedures for condylar head fractures (CHFs) are far from reaching a consensus. The aim of this study was to evaluate the changes in disc status for anteromedial disc displacement with anchorage (AMDDwA) and without anchorage (AMDDwoA - just suturing to the adjacent TMJ soft tissue) in adult CHFs, to get a better understanding of this very complex process and to show that rigid disc anchorage is an essential technique for the treatment of CHF during the open reduction and internal fixation (ORIF)...

Introduction: Surgical treatment of condylar neck fractures requires an extraoral approach when, due to the degree of difficulty of the fracture, an intraoral approach or an endoscopically supported treatment is not possible. In contrast to the cosmetically more favorable oral approach, extraoral approaches offer a better overview of the operating field and thus an easier fracture repositioning and osteosynthetic treatment. In 2007, Marti et al. described a minimal pre- and retroauricular incision with no extension to the hair-bearing skin and which aimed to improve the parotidectomy approach...

Supracondylar femur fractures represent a challenging and common injury treated by many orthopedic surgeons. An array of surgical fixation options has been developed to help the treating surgeon restore normal anatomic alignment of these fractures, and lateral precontoured condylar femoral locking plates have become a common implant for most surgeons in treating these fractures. Though these precontoured plates provide significant benefit to the treating physician in regards to gaining appropriate bony fixation, common technical errors that may lead to malalignment when utilizing these plates have been described...

BACKGROUND: Fresh frozen human femurs are considered "the gold standard" in biomechanical studies of hip fractures, resembling the in vivo situation mostly. A more readily available alternative is formalin embalmed femurs. However, to which extent formalin affects key features of bone; its mechanical properties, bone mineral content and their mutual relationship over time, remains unknown. Accordingly, we measured the mineral parameters and related them to the mechanical properties of formalin fixed femurs after long-term storage...

PURPOSE: Fractures of the condylar process are frequent. Ideal management of these fractures, as discussed in the literature, is controversial. Some recent meta-analyses have favored open reduction and internal fixation using various approaches. A strictly transoral approach has been described to minimize scarring and risk of facial nerve injury but has restricted visibility. This retrospective study analyzed outcomes of patients with unilateral mandibular condyle fractures who were treated by open reduction and internal fixation through an endoscopic-assisted transoral approach...

BACKGROUND: Limited data have been published regarding the typical coronal dimensions of the femur and tibia and how they relate to each other. This can be used to aid in judging optimal operative reduction of tibial plateau fractures. The purpose of the present study was to quantify the width of tibial plateau in relation to the distal femur. METHODS: We reviewed 3D computed tomography (CT) scans taken between 2013 and 2016 of 42 patients (84 knees). We measured positions of the lateral tibial condyle with respect to the lateral femoral condyle (dLC) and the medial tibial condyle with respect to the medial femoral condyle (dMC) in the coronal plane...

This case report describes diagnosis, treatment, and outcome of maxillofacial trauma in a 9-week-old shih tzu. In addition to an open left mandibular body fracture and a right condylar process fracture, there were several relatively stable and minimally displaced right maxillary fractures. The torn soft tissues associated with the left mandibular body fracture were sutured closed, and a tape muzzle was placed. Due to sufficient fracture healing at the 2-week recheck examination, the tape muzzle was removed...

Background: Mandibular condylar fractures commonly occur after trauma and account for 25 to 35% of all mandibular fractures; its appropriate therapy still remains a point of controversy in children. The purpose of this paper is to describe the treatment of an 11-years-old male patient affected by neck-condylar fracture as result of trauma in evolutive age. Methods: No surgical treatment was performed. A functional therapy was applied with a jaw splint. A closed treatment for mandibular condyle fractures was preferred because the amount of condylar displacement wasn't considerable...
