BACKGROUND: Arthrocentesis has an effect of washing out inflammatory products that accumulate in the joint compartment of a dysfunctional TMJ. The procedure removes inflammatory cytokines, which are pain-causing substances, for early reduction of TMJ pain and quick recovery of jaw function, thus increasing the possibility of a successful rehabilitation. OBJECTIVE: The aim of the present study was to investigate the relationship between arthroscopy synovitis grade in patients with unilateral high condylar fractures and concentrations of the pro-inflammatory cytokines tumor necrosis factor (TNF)-alpha as well as of matrix metalloproteinases (MMPs) in washed-out synovial fluid (SF) samples obtained from those patients...

A series of surgical cases operated in our unit are considered to analyze and evaluate the different techniques and sequencing employed in the surgical management of double/triple mandibular fractures involving a condylar fracture. Deviating from the normal sequence of reducing and fixing the dentate segment first, we addressed the condylar segment first. A combination of different approaches for different cases such as a periangular with a vestibular, a preauricular and a retromandibular with a vestibular were used according to the type of fractures...

The purpose of this study was to investigate whether the location of the hinge affects the incidence of hinge fracture during medial closing-wedge distal femoral varus osteotomy (DFVO). Twenty knees from 10 fresh-frozen human cadavers (mean age, 75 ± 17 years) were used to perform uniplanar medial closing-wedge DFVO with a 7-mm wedge. Each specimen was randomly assigned to either group A (supracondylar hinge) or group B (lateral condylar hinge). The incidence of hinge fracture and stability was compared between both groups after uniplanar medial closing-wedge DFVO...

Aims Displaced fractures of the lateral condyle of the humerus are frequently managed surgically with the aim of avoiding nonunion, malunion, disturbances of growth and later arthritis. The ideal method of fixation is however not known, and treatment varies between surgeons and hospitals. The aim of this study was to compare the outcome of two well-established forms of surgical treatment, Kirschner wire (K-wire) and screw fixation. Patients and Methods A retrospective cohort study of children who underwent surgical treatment for a fracture of the lateral condyle of the humerus between January 2005 and December 2014 at two centres was undertaken...

Although rarely reported in the literature, serious occipital and condylar fractures have been diagnosed more often with the widespread use of computed cranial tomography in traumas. In this paper, a 16-year-old female with a left occipital fracture extending from the left occipital condyle anterior of the hypoglossal canal to the inferior part of the clivus is presented. The fracture which had caused a neurological deficit was cured with conservative treatment. For delayed hypoglossal nerve paralysis due to swelling within the canal, methylprednisolone was started, and a complete cure was attained in about 10 days...

Trauma to the mandible can occasionally be a life-threatening event. Although extremely rare with only 56 reported patients in the English language, fracture of the floor of the middle cranial fossa with protrusion of the mandibular condyle into the middle cranial fossa was first reported in 1963 by Dingman. The authors review the anatomy of the temporomandibular joint in relation to the middle cranial fossa and demonstrate the possible complications due to condylar intrusion with anatomical dissection.

Mandibulo-maxillary fixation (MMF) is indispensable for mandibular fracture treatment. Various means for MMF have been proposed, of which arch bars are widely considered to be the mainstay. However, disadvantages to this method have initiated a quest for an alternative, leading to the introduction of MMF screws. MMF screws have frequently been criticized for poor stability of fracture sites, root damage, hardware failure, and nerve damage. We retrospectively evaluate the FAMI (Fixation and Adaptation in Mandibular Injuries) screw in mandibular fracture treatment by scanning for clinically and radiologically visible complications...

Upper cervical fracture-dislocations are series of pathological injuries occurred in occipital, atlas and axis caused by traumatic impact, which often results in severe clinical consequences, such as paraplegia, quadriplegia, and even death. In light of the potential severe clinical outcomes, it is important to define the type of upper cervical fracture-dislocations depending on which the clinician can deal with the disease properly. Owing to its specific anatomical structures, the upper cervical fractures occurr to the unique osseous structures or ligamentous connections always present in predictable patterns...
