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...

Facial asymmetry, following early childhood condylar trauma, is a common complaint among patients who seek surgical treatment. G.D.M., a 27-year-old male patient, sought professional help to correct his cosmetic flaw, caused by a condylar fracture when he was 8-years-old. After the proper orthodontic treatment, he underwent a double jaw orthognathic surgery and, 9 months later, a second one to correct the remaining asymmetry. Two years after this second procedure, the patient is still under surveillance and has no complaints...

Management of condylar fractures is a highly controversial and debatable area. Open reduction and internal fixation (ORIF) using an extraoral approach has certain benefits over the nonsurgical treatment. Risk of damage to the facial nerve and an extraoral scar remains constant deterrents. An endoscopic-assisted ORIF offers an intraoral approach, thus eliminating consequences such as scarring. Though this technique offers unparalleled advantages, it is associated with a steep learning curve. Surgical results improve only with patience and experience...

Diffuse sclerosing osteomyelitis (DSO) of the mandible is a poorly understood chronic disease. It is assumed to be a form of chronic osteomyelitis. Other forms of chronic osteomyelitis are chronic suppurative osteomyelitis (CSO) and osteoradionecrosis (ORN). This study aimed to investigate radiographic characteristics of DSO and compare these findings with the radiographic characteristics of CSO and ORN in order to radiographically distinguish these three diseases. In this retrospective study, 33 patients were clinically diagnosed with DSO (13), CSO (6), or ORN (14)...

BACKGROUND: Mandibular fractures, especially condylar fractures, are one of the most common facial fractures. Trauma to this region could possibly compromise masticatory performance, which is a vital function for humans. OBJECTIVE: To objectively determine masticatory performance (Mixing Ability Test; MAT) in patients treated for a unilateral condylar fracture, thereby comparing patients in open and closed treatment groups, and assessing whether there is a positive relationship between this performance and subjective mandibular function (Mandibular Functional Impairment Questionnaire; MFIQ)...
