Traumatic hip joint dislocations account for 2-5% of total joint dislocations. Bilateral asymmetric hip joint dislocation with anteriorly and posteriorly dislocation is an even more rare case because it was according to G. Loupasis reported in 11 cases only since 1879. We want to report 2 cases of bilateral asymmetric hip joint dislocation with unilateral acatabulum fracture which happened in our hospital. Bilateral asymmetric dislocation of hip joint accompanied by unilateral fracture of acetabulum is a very rare case so statistical verification cannot be done. However, close examinations are required at early treatment and follow-up because the patterns of dislocation and fracture of hip joint are variable and an orthopedic emergent condition and several complications may occur at both hip joints.

Total Hip Replacement in a patient with chronic coxofemoral joint dislocation is a challenging problem because chronic coxofemoral joint dislocation causes severe morphological changes. These challenging factors make surgery more difficult and increase the possibility of postoperative complications including cup implant dislocation and prosthetic joint luxation. All patients were diagnosed having at least 2 months of coxofemoral joint dislocation. On physical examination, crepitus was noted in the coxofemoral joint. Radiographs revealed hip joint dislocation with mild to severe degenerative changes. Total hip replacement was planned for all patients. Dorsal acetabular rim deficiency in 3 cases was augmented using a locking plate and polymethylmethacrylate bone cement. All cases have shown difficulty in prosthetic joint reduction. Pectineus and rectus femoris muscle origin were released in all cases. At 12 months follow up, all patients showed satisfactory ambulation. The issues on perioperative prosthetic joint reduction and luxation due to chronic coxofemoral joint luxation with muscle contracture and dorsal acetabular rim deficiency can be resolved by muscle releasing and dorsal acetabular rim augmentation.

Chronic temporomandibular joint dislocation is defined as an acute dislocation that cannot be reduced or that recurs for more than one month. The management of dislocation depends on patient status and the duration of dislocation and ranges from conservative reduction to a surgical approach. In the present cases, a 64-year-old male was referred to our department for treatment of chronic dislocation for 6 weeks. The dislocation might be occurred by endotracheal intubation. A 70-year-old female was referred to our department with repeat right condyle dislocation after reduction of dislocation at a local clinic. When she visited for later treatment of new dentures, her condyle had been dislocated again for several weeks. In both cases, we tried to treat the dislocation with several manipulations, which were unsuccessful. Finally, chronic dislocation was successfully treated by surgical traction under general anesthesia without relapse. Surgical traction is a simple, effective option with the lowest morbidity of surgical procedures for chronic dislocation when conservative reduction is unsuccessful.

Sternoclavicular joint posterior dislocations are considered a very uncommon, and type of injury where if esophagus or airway injury occurs behind the clavicle, it poses a high risk to the patient. In addition, if epiphyseal fracture occurs as a result of the sternoclavicular joint posterior dislocation, surgical treatment is often required. However, in the absence of a complete ossification of the clavicle, it is difficult to differentiate between a simple dislocation and epiphyseal fracture-dislocation solely based on simple radiographs or computed tomography scans. In this case report, the authors present a case in which a sternoclavicular joint posterior dislocation was diagnosed in a 14-year-old male athlete. The case report discusses how the posterior dislocation without epiphyseal fracture was diagnosed using an ultrasound and subsequently treated with successful outcomes using manual reduction. The case report presents our findings along with discussion that includes a literature review of relevant research.

A subtalar dislocation of the foot is a dislocation of the talonavicular and talocalcaneal joint while the tibiotalar relationship is unchanged. Posterior subtalar dislocation in particular, is a extremely rare. Only a few cases were reported previously in the literature. We treated a 25 year-old man who sustained the posterior subtalar dislocation in high energy traffic accident. The dislocation of subtalar joint was reduced by closed means with excellent clinical result. In this paper, we report 1 case of posterior dislocation of the subtalar joint and describe the pathomechanics, diagnosis, and treatment.

Temporomandibular joint (TMJ) dislocation is defined that the disc-condyle complex is positioned anterior to the articular eminence in the open mouth position, and is unable to return to a normal closed mouth position without a manipulative maneuver. TMJ dislocation can recur habitually and result several problems to patients such as discomfort, pain, fear, and anxiety. The only definitive treatment for TMJ dislocation is surgical alteration of the joint itself. In most cases, however, a surgical procedure is far too aggressive for the symptoms experienced by the patient. In addition, the effect of surgical treatment may be insufficient, and the recurrence have been reported. It is also possible to develop several complications after surgical treatment. Therefore much effort should be directed at supportive therapy in an attempt to eliminate the disorder or at least reduce the symptom to tolerable levels. Through this cases the authors present favorable treatment outcome using occlusal splint with the patient of TMJ dislocation. Occlusal splint therapy can be considered as easy, safe, and useful non-invasive modality to treatment of TMJ dislocation.

Temporomandibular joint dislocation causes considerable pain, discomfort, and swelling. The anatomic construction of the articular fossa and the eminentia articularis may predispose to dislocation, and weakness of the connective tissue forming the capsule is believed to be a predisposing factor. The capsule may be stretched and, more rarely, torn. Dislocation may be unilateral or bilateral and may occur spontaneously after stretching of the mouth to its extreme open position, such as during a yawn or during a routine dental operation. Manual reduction with the patient under muscle-relaxing condition or anesthesia is recommended method. After the reduction of an acute dislocation, immobilization of the jaw is recommended to allow the stretched and sometimes torn capsule to heal, thus preventing recurrence. A Barton's bandage may be applied for 2 to 3 weeks to prevent the patient from opening the jaw too wide. But, it results in recurrent dislocation in the neurologically disabled patient, because of loose intermaxillary fixation. This is a case report about management of recurrent temporomandibular joint dislocation by multiple loop wirings and intermaxillary elastics in cerebrovascular accident patient.

Reasonable estimates of tunnel lining dislocations in the operation stage, especially under longitudinal differential settlement, are important for the design of waterproof gaskets. In this paper, a modified shell-joint model is proposed to calculate shield tunnel dislocations under longitudinal differential settlement, with the ability to consider the nonlinear shear stiffness of the joint. In the case of shell elements in the model, an elastoplastic damage constitutive model was adopted to describe the nonlinear stress-strain relationship of concrete. After verifying its applicability and correctness against a full-scale tunnel test and a joint shear test, the proposed model was used to analyze the dislocation behaviors of a shield tunnel in Shanghai Metro Line 2 under longitudinal differential settlement. Based on the results, when the tunnel structure is solely subjected to water-earth load, circumferential and longitudinal joint dislocations are all less than 0.1 mm. When the tunnel suffers longitudinal differential settlement and the curvature radius of the differential settlement is less than 300 m, although maximum longitudinal joint dislocation is still less than 0.1 mm, the maximum circumferential joint dislocation is approximately 10.3 mm, which leads to leakage and damage of the tunnel structure. However, with concavo-convex tenons applied to circumferential joints, the maximum dislocation value reduces to 4.5 mm.

흉쇄관절의 외상성 탈구는 드문 손상으로 전방 탈구가 후방 탈구에 비하여 흔하다. 후방 탈구는 종격동 구조물을 압박하여 잠재적 위험성이 있다고 잘 알려져 있지만 전방 탈구는 그러한 위험성에 대한 고려가 없었다. 전방 탈구라도 흉골 골절의 전방 각형성과 동반된 경우에 후방 탈구와 마찬가지로 종격동 압박이 발생 가능하며 그로인한 위험성이 있다. 본 저자들은 종격동 압박 증상이 있는 흉골 골절과 동반된 외상성 흉쇄관절 전방 탈구에 대하여 금속판을 이용해 수술적 치료를 시행하였고 비교적 양호한 결과를 얻었다. 이는 국내외에서 매우 드물게 보고되는 사례로 이를 문헌고찰과 함께 보고하고자 한다.

Fracture of the clavicle and dislocation of the acromioclavicular joint occur commonly as separate injuries. However, complete acromioclavicular dislocation with an ipsilateral clavicle fracture is quite rare. We experienced a case of acromioclavicular joint dislocation associated with fracture of clavicle and brachial plexus injury treated by open reduction and internal fixation.
