105 Borderland Military Hospital of Żary, 68-200 Żary, Poland. Electronic address:

The paper presents an innovative osteofixation system designed for bone fracture stabilization. Its special feature, which makes it different from other similar systems, is the possibility to precisely adjust the implant to the shape of the bone. Such a precise adjustment is particularly important in the case of multiple fractures, where proper stabilization is a condition for restoring bone geometry and thus obtaining the biomechanical function of a given segment of the body lost due to fracture.

Comparing maximal forces in resorbable poly-L-lactic acid and titanium plates for mandibular fracture fixation.

Heliyon 2020 Apr 3;6(4):e03705. Epub 2020 Apr 3.

Department of Plastic Surgery, Vanderbilt University Medical Center, Nashville, TN, USA.

Treatment for mandibular fractures is commonly performed via open reduction fixation with mini titanium or resorbable plates and screws. The investigators hypothesized differences in maximum mechanical stress forces and deflection with each plating material; however, it was proposed that the experimental forces withstood by the resorbable system would be enough to withstand normal forces produced during mastication. The sample was composed of fresh cadaver mandibles that were harvested, fractured, and fixated with plates and screws. Read More

Masticatory Loading and Ossification of the Mandibular Symphysis during Anthropoid Origins.

Sci Rep 2020 Apr 6;10(1):5950. Epub 2020 Apr 6.

Department of Anatomy and Neurobiology, Northeast Ohio Medical University, Rootstown, Ohio, 44272, USA.

An ossified or 'fused' mandibular symphysis characterizes the origins of the Anthropoidea, a primate suborder that includes humans. Longstanding debate about the adaptive significance of variation in this jaw joint centers on whether a bony symphysis is stronger than an unfused one spanned by cartilage and ligaments. To provide essential information regarding mechanical performance, intact adult symphyses from representative primates and scandentians were loaded ex vivo to simulate stresses during biting and chewing - dorsoventral (DV) shear and lateral transverse bending ('wishboning').

Feline skull injuries: Treatment goals and recommended approaches.

J Feline Med Surg 2020 Mar;22(3):229-240

Department of Animal Medicine and Surgery, Universidad CEU Cardenal Herrera, C/Ramón y Cajal s/n, Alfara del Patriarca, 46115 Valencia, Spain.

Practical Relevance: Skull trauma in cats, which includes fractures of the mandible and maxilla, as well as temporomandibular joint (TMJ) conditions, is frequently encountered in general practice.

Clinical Approach: Head trauma requires immediate attention and the initial approach should be focused on stabilisation of the patient and evaluation of the major body systems, including respiratory and cardiovascular assessment, and neurological and ophthalmic examination. The head, oral occlusion and the patient's ability to open and close the mouth should be carefully evaluated. Read More

Insights Imaging 2020 Feb 19;11(1):30. Epub 2020 Feb 19.

Department of Experimental and Clinical Biomedical Sciences, Radiodiagnostic Unit n. 2, University of Florence-Azienda Ospedaliero-Universitaria Careggi, Largo Brambilla 3, 50134, Florence, Italy.

Mandibular fractures are among the most common maxillofacial fractures observed in emergency rooms and are mainly caused by road accidents. The clinical features of mandibular fractures include malocclusion and loss of mandibular function. Panoramic radiography is usually limited to isolated lesions, whereas computed tomography is the tool of choice for all other facial traumatic events. Read More

Pediatric Mandibular Condylar Fractures With Concomitant Cervical Spine Injury: A Treatment Protocol for Prevention of Temporomandibular Joint Ankylosis.

J Craniofac Surg 2020 May/Jun;31(3):e248-e250

Children's Hospital of Pittsburgh, University of Pittsburgh Medical Center, Pittsburgh, PA.

In pediatric patients with mandible fractures and concomitant cervical spine injury (CSI), treatment strategies may occasionally compete: condylar fractures require functional therapy with range of motion exercises of the temporomandibular joint (TMJ), while CSI requires neck immobilization. The authors report the case of a child presenting with bilateral condylar head fractures, a right parasymphyseal fracture, and concomitant CSI treated with cervical collar immobilization, who ultimately developed TMJ ankylosis. Here, the authors review mandibular condylar fracture management and suggest an approach for the pediatric patient presenting with condylar fractures and concomitant CSI requiring immobilization.

Surgical Management of Primary Chronic Osteomyelitis of the Jaws: The Use of Computer-Aided-Design/Computer-Aided Manufacturing Technology for Segmental Mandibular Resection.

J Craniofac Surg 2020 Mar/Apr;31(2):e156-e161

Department of General Surgery, Section of Maxillo Facial Surgery, Policlinico Vittorio Emanuele, University of Catania, Catania.

The term osteomyelitis of the jaws identifies different pathological patterns characterized by the involvement of the cortical bone and bone marrow in osteoarticular infections.At the head and neck level, the segment most affected by osteomyelitis is the mandible and in most of the cases the cause of the infection is bacterial, as a result of pulp or periodontal infections, post-extraction alveolitis, foreign bodies and fractures. The mandibular PCO often presents with an insidious onset, without a striking acute phase, and it is characterized by recurrent episodes of pain, swelling, lockjaw, latero-cervical lymphadenopathy, without signs of suppuration.
