Heterotopic ossification of the elbow treated with surgical resection: risk factors, bony ankylosis, and complications.
When the pathological stimulus is extensive ([greater than or equal to]20%) and there is proximity to the alveolar bone and/or the bone grafts are nearly to the root (40), the bone repair process overlaps the PDL reparation, resulting in root surface fusion, with the adjacent bone initiating an ankylosis (41).
The scans were reviewed by an experienced radiologist, who made anatomic measurements at the level of the cricoarytenoid joint to determine the presence and degree of ankylosis, narrowing, erosion, and density changes.
The only potential disadvantage of this technique is if the appropriate degree of abduction is not achieved, there will be a limited time of opportunity to change the position of the arytenoid before a joint ankylosis ensues.
The teeth were clinically vital, radio-graphically normal, with no pulp obliteration, and had no signs and symptoms of ankylosis or root resorption (Figures 7 and 8).
The radiographic characteristics as ossification of the anterior longitudinal ligament and ankylosis of the adjacent segments seem to be risk factors for the formation of a ROP [18].
It not only provides bony fusion and ankylosis but also provides stability and freedom from pain.
According to the medical history of the patient, she was previously diagnosed with congenital temporomandibular joint ankylosis (CTMJA).
The initial step in this approach requires a reading of the introductory paragraph of the first subsection of the Musculoskeletal --The Spine section, "Evaluation of the Spine." The last paragraph of this three-paragraph introduction reads: "After determination of the impairment from a spinal disorder has been obtained that value must be combined with the appropriate value of residual objective signs for ankylosis, and spinal cord and/or spinal nerve injury." (14) It is, thus, clear that the guides contemplate that an injured worker should obtain a rating for ankylosis, and possibly for any spinal nerve injuries, in addition to a rating for a disorder of the spine.
They recommended this type of splint and amount of time, because it allows physiological movements of the teeth during the healing process and it also results in a reduction of the incidence of ankylosis. In 2001, Vasconcelos et al.
The condition is called bilateral temporomandibular joint (TMJ) ankylosis. A condition in which the jaw joint becomes a mass of fused bone after improper fracture healing.
