The Treatment of Temporomandibular Joint Dislocation.
Deutsches Arzteblatt international, 2018Co-Authors: Ulla Prechel, Peter Ottl, Oliver M Ahlers, Andreas NeffAbstract:Background The estimated incidence of temporomandibular Joint Dislocation in Germany is at least 25/100 000 per year. A correct diagnosis and the initiation of appropriate treatment without delay are essential if permanent damage to the Joint is to be avoided. Methods This review is based on pertinent publications retrieved by a systematic search in the PubMed, Cochrane, Embase, and ZB Med databases. Results The initial search yielded 24 650 hits; duplicates were removed and 136 studies were chosen for further analysis. The diagnosis of temporomandibular Joint Dislocation is generally made clinically from the finding of a lower jaw that is fixed in the open position. Acute Dislocations are manually repositioned at once. The most common method is Hippocratic repositioning, in which the physician's thumb is placed laterally next to the teeth and the other fingers are placed on the lower surface of the lower jaw. The physician then exerts pressure, first caudally, then dorsally. Repositioning is carried out in two steps. For Dislocations that have been present for a longer time, manual repositioning may be ineffective and surgery may be needed. Recurrent Dislocation can be treated in a minimally invasive way with botulinum toxin injections or autologous blood therapy. Surgery may be needed if these methods are ineffective. Conclusion There have been no more than a few randomized, controlled trials of treatments for temporomandibular Joint Dislocation, in particular concerning minimally invasive and open surgical treatments, and therefore only limited evidence-based conclusions can be drawn. Nonetheless, the diagnostic and therapeutic standards that have been established in recent years have gained wide international acceptance.

botulinum neurotoxin injection for the treatment of recurrent temporomandibular Joint Dislocation with and without neurogenic muscular hyperactivity
Toxins, 2018Co-Authors: Kazuya YoshidaAbstract:The aim of this study was to compare treatment outcomes following intramuscular injection of botulinum neurotoxin (BoNT) in patients with recurrent temporomandibular Joint Dislocation, with and without muscle hyperactivity due to neurological diseases. Thirty-two patients (19 women and 13 men, mean age: 62.3 years) with recurrent temporomandibular Joint Dislocation were divided into two groups: neurogenic (8 women and 12 men) and habitual (11 women and 1 man). The neurogenic group included patients having neurological disorders, such as Parkinson’s disease or oromandibular dystonia, that are accompanied by muscle hyperactivity. BoNT was administered via intraoral injection to the inferior head of the lateral pterygoid muscle. In total, BoNT injection was administered 102 times (mean 3.2 times/patient). The mean follow-up duration was 29.5 months. The neurogenic group was significantly (p < 0.001) younger (47.3 years) than the habitual group (84.8 years) and required significantly (p < 0.01) more injections (4.1 versus 1.7 times) to achieve a positive outcome. No significant immediate or delayed complications occurred. Thus, intramuscular injection of BoNT into the lateral pterygoid muscle is an effective and safe treatment for habitual temporomandibular Joint Dislocation. More injections are required in cases of neurogenic temporomandibular Joint Dislocation than in those of habitual Dislocation without muscle hyperactivity.

Palmaris longus tendon transfer for treatment of distal radioulnar Joint Dislocation
Chinese Journal of Hand Surgery, 1996Co-Authors: Pla HuzhouAbstract:Objective: To find the rationale of palmaris longus tendon transfer for treatment of distal radioulnar Joint Dislocation. Methods: The width and thickness of each segment of palmaris longus tendon were measured in 30 upper limb specimens. Traction test was done in 9 tendons from fresh cadavers. In 30 patients clinically, the palmaris longus tendon was pulled through the holes made in the radius and the ulna in '8' shape and reduced the gap of the distal radioulnar Joint that was departed, and then the tendon was anchored on the palmer aponeurosis. Results: After follow-up of 5 months to 6 years, the gap of distal radioulnar Joint was reduced to 1.0～2.5 mm from 3.0～4.0 mm before surgery in x-ray. The outcomes were satisfactory. Conclusions: The length and width of palmaris longus tendon is suitable for this technique. The strength is adequate to pull the Joint together. This technique is simple and effective for treatment of old distal radioulnar Joint Dislocation,

Treatment of distal radioulnar Joint Dislocation and arthritis by Sauve-Kapandji procedure
Chinese Journal of Hand Surgery, 2008Co-Authors: Zhen-bing ChenAbstract:Objective To evaluate the clinical effectiveness of Sauve-Kapandji technique for the treatment of distal radioulnar Joint Dislocation and arthritis. Methods Twelve cases of distal radioulnar Joint Dislocation and arthritis were treated by Sauve-Kapandji technique. All cases were followed up for 9-32 months, with an average of 16 months. Pre-and postoperative wrist pain degree, wrist range of motion, grip strength and X-rays of wrist were evaluated. According to X-rays, the distance between radius and ulna and radiological union were observed. Function of the wrist was evaluated by Mayo scores. Self-evaluations of postoperative wrist function were evaluated by DASH questionnaire. Results Wrist pain score was 39±17 preoperatively and 23±13 postoperatively. The preoperative range of motion of ulnar and radial deviation was 26°±11°, while the postoperative range Was 41°±12°. Forearm rotation was 84°±21° preoperatively and 139°±33° postoperatively. The preoperative grip strength was 12.8±3.6kg, while postoperative was 24.0±7.4kg. The value of Mayo scores was 43±13 preoperatively and 73±16 postoperatively. Among the 12 cases, 3 were graded as excellent, 4 as good, 3 as fair and 2 as poor. The postoperative DASH score was 31±10 as compared to the preoperative 57±14. X-rays showed union of the distal radioulnar Joint and ulnar bone graft in all cases. Conclusion Sauve-Kapandji operation can relieve wrist pain, increase rotation and grip strength and improve wrist function in patients with distal radioulnar Joint Dislocation and arthritis. Key words: Arthrodesis; Treatment outcome; Dislocation of the distal radioulnar Joint
