The phrase "articular head" is not correct in written English.
It seems to be a misspelling or misinterpretation of "articular head," which refers to a specific anatomical structure in the context of joints.
Example: "The articular head of the femur fits into the acetabulum of the pelvis."
Alternatives: "articular surface" or "joint head."
Its pathological displacement results in lack of coordination of the articular head and disc during the mandible movements, causing acoustic symptoms in the form of glitches.
At the same time, compression by the articular head may damage the tympanic cord, leading to contracture of the stapedius muscle in a reflex mechanism transmitted via the facial nerve.
Acoustic symptoms within the joints, manifested as popping and cracking sounds, are an evidence of the lack of coordination between the articular head temporomandibular joint articular discs during mandible movements [ 2].
(iii) Microanatomy and histology observed in serial polished sections The polished sections reveal changes in microanatomy from the mid-diaphysis (section 1) to the proximal head of the humerus (sections 2 to 5) and then from the mid-diaphysis to the distal articular head (sections 6 to 9).
Geometric analysis software, 3D Reshaper (Technodigit, Gleizé, France), was used to deduce the coordinates of the articular head center by fitting a sphere to its point cloud, and the center of the acetabular component by fitting a circle to its point array, in both cases using the method of least squares.
We applied traction of 5 kg to the ipsilateral ankle compared to the articulation coxofemoral joint in order to obtain a paraphysiological diastase of the articular heads and to improve the spread of the intra-articular contrast agent.
This is due to missing teeth not being replaced, particularly in the support zones, as well as to pathological teeth attrition, promoting the reduction in occlusal height and posterior translocation of articular heads in central occlusion [ 23, 24].
The inclusion criteria included temporomandibular joint dysfunction pain manifested as lack of coordination in operation of articular heads and disc (disc translocation with or without disc blockade/crackling sounds/) and dysfunctions presenting with excessive masticatory muscle tone as the dominant problem and lack of benefits from previous treatment methods.
The reported causes for otolaryngological symptoms include common embryonic origin of the ear and the masseter muscles and the compression of vessels, nerves, and ligaments by posteriorly translocated articular heads of the mandible in the middle and inner ear regions [ 3, 4].
The purpose of this study was to evaluate high-energy, partial articular radial head fractures and identify any associated injuries of the elbow in reference to fracture location in the radial head.
The thickness of the articular surface, head height, is equally variable but shows a striking proportionality to the radius of curvature.
