Fracture and dislocation of the four lateral metatarsal head and neck at the metatarsophalangeal joint, which may be associated with a hyperextension force, axial load, and additional rotating force, has rarely been reported. The patient was a 32-year-old man who sustained the injury in a motor vehicle accident. Manual reduction was easily performed but maintenance of reduction was difficult, due to the associated fractures of the metatarsal necks. Thus percutaneous internal fixation with Kirshner's wires was required.

Recurrent dislocation of elbow joint occurs relatively rarely by the injury of the collateral ligament which contributes elbow joint stability. Among them, posterolateral rotatory instability occurs by the injury to the lateral ulnar collateral ligament. We experienced a case of recurrent dislocation of elbow joint due to posterolateral rotatory instability. We treated operatively with lateral ulnar collateral ligament reconstruction using the palmaris longus tendon by technique of Nestor et al. We report it with literature analysis.

Clavicular hook plate is known to be an effective treatment on acromioclavicular (AC) joint injury, but there have been some reports of complications, like osteolysis and bony erosion of the undersurface of acromion. Fifty-five year old male underwent open reduction and hook plate insertion on Rockwood type 5 acromioclavicular joint dislocation. He complained of protrusion of posterior acromion at 1 month after the surgery, and acromial fracture was noted in simple radiographs. The hook plate was removed and any other treatment for osteosynthesis was refused by the patient. At the 18 months after the surgery, the patient had no pain and a full range of motion with no tenderness around the shoulder joint. After two years, plain radiographs revealed complete bony union of the acromion fracture.

Mandibular condylar hyperplasia is an uncommon condition of excessive unilateral growth of the condyle causing facial asymmetry and occlusal alterations. The etiology of condylar hyperplasia is unclear, but several factors are suspected, including previous trauma, hormonal disturbances, and abnormal functional loadings. Acute or chronic recurrent dislocation of temporomandibular joint (TMJ) is common, but long-standing dislocation is rare. We present two cases of the exophytic condylar hyperplasia that lasted for over 20 years with TMJ dislocation. In both cases, we performed a condyloplasty to restore normal occlusion and facial symmetry, with satisfactory results.

Purpose : There has been considerable controversy as to the method of the treatment of acute acromioclavicular joint dislocation classified to type III injury. The purpose of this study is to compare the conservative and operative treatment of the type III acute acromioclavicular joint dislocation in terms of clinical and radiological results. Materials and Methods: We treated 31 cases of acute, type III acromioclavicular joint dislocation, 17 cases were treated by operative methods and 14 patients by conservative treatment, and 1 year minimum follow-up was done from January 1990 to January 1996. We used UCLA Shoulder Rating Scale for clinical results. And for the radiological results coracoclaviclar distance were measured. We used Fisher's exact test for statistical analysis of results between the two treatment methods. Results: Fifteen(88.2%) of seventeen patients in operative treatment and eleven(78.6%) of fourteen patients in nonoperative treatment were rated excellent or good on the UCLA rating scale. In radiographic evaluation, the average coracoclavicular distances of preoperative state, immediate postoperation(or postreduction) and last follow-up were as follows. In operative cases, it was 1.75±0.21mm, 1.14±0.24mm and 1.33± 0.22mm respectively. In nonoperative cases, it was 1.65±0.14mm, 1.26±0.26mm, and 1.42±0.27mm respectively. Conclusion : This study demonstrated that there was no significant difference in clinical and radiological results between the operative and nonoperative treatment groups. So, nonoperative treatment is recommended for acute type III acromioclavicular dislocation as general rule.

Purpose: We wanted to evaluate the clinical outcomes after operative treatment using two suture anchors and Kirschner wire for treating acute Rockwood type V acromioclavicular joint dislocation Materials and Methods: Between May 2006 and May 2009, 10 patients underwent surgical treatment for acute Rockwood type V acromioclavicular joint dislocation using two suture anchors and Kirschner wire and they were followed for a mean of 12.0 (range: 7-31) months. We analyzed the functional results by the Korean shoulder score, the Constant-Murley score and the reduction state of the acromioclavicular joint at the last follow-up. Results: All the cases achieved a satisfactory outcome. The mean Korean shoulder score was 89.9 (range: 81-100) points and the mean Constant-Murley score was 87.8 (range: 82-93) points. According to the radiologic findings, 8 patients achieved anatomical reduction of the acromioclavicular joint: there was a slight loss of reduction in one patient and a partial loss of reduction in one patient. None of the patients had deep infection or re-dislocation. Conclusion: The operative treatment using two suture anchors and Kirschner wire may be used for acute Rockwood type V acromioclavicular joint dislocation, and it has an advantage in that it can prevent chondral injury of the joint.

Purpose: We evaluate clinical manifestations and radiologic features of ankle fracture & dislocation, as well as the usefulness of computed tomography on posterior ankle fracture & dislocation to study factors contributing to ankle fracture & dislocation. Material and Methods: Ankle dislocation was defined as the center of talar body being translated over the cortex of tibia on AP or lateral view on simple X-ray. Surgical treatments of 30 patients from January 2007 to March 2012 were categorized according to the injury mechanism, the direction of dislocation and fracture site. Joint involvement of posterior malleoalr fracture was evaluated through simple x-ray and computed tomography. We treated surgically if posterior malleolus fracture involves more than 25% of dital tibial articular surface. Thereafter, clinical outcomes were identified through radiographs and by using the AOFAS score. Results: The mean age was 42(13-78) years old, and slip down was the most common injury mechanism (13 cases). Car accident (6 cases) and fall accident (4 cases) were the next frequently found injury mechanisms. As for the types of ankle fracture, posterior fracture and dislocation (21 cases, 43.3%) was most commonly found. Out of these 21 cases, 15 cases involved trimalleolar fracture, and 19 cases were associated with posterior malleolar fracture. Danis-weber type B and C patients were 11 cases and 10 cases respectively. Articular involvement of posterior malleolar fracture turned out to be average 27.9%(5.1%~49.1%) on simple x-ray. The rate was evaluated as average 31.7%(12.6%~55.3%) on computed tomography which was conducted 15 times, and led us to more meaningful data. Conclusion: Anterolateral fracture and dislocation often accompanied open dislocation. Posterior fracture dislocation was most commonly found. Posterior malleolus was an important factor that ensures posterior stability of the ankle joint. Computed tomograph is useful to evaluate the articular involvement of posterior malleolar fracture.

A 22-year-old man was hospitalized with a sternoclavicular joint (SCJ) dislocation caused by a traffic accident. Surgical reduction and fixation of the SCJ were performed using a T-plate. SCJ dislocation is rare, accounting for less than 1% of all dislocations, and is usually treated conservatively, although severe cases may require surgery. Surgery typically involves joint reduction and fixation using an autologous tendon graft, but this has disadvantages such as the requirement for additional surgery to obtain autologous tissue and an extended operative time. To overcome these issues, here, we performed a simple SCJ reduction and fixation using a T-plate and achieved good results.

Purpose : The aim of this study was to investigate the effect of the autologous blood injection (ABI) for chronic recurrent temporomandibular joint (TMJ) dislocation using magnetic resonance imaging (MRI). Materials and Methods : ABI was applied to 14 patients who had chronic recurrent TMJ dislocation. MRIs of the patients were taken and compared before and one month after the injection. Results : All of the patients had no dislocations of their TMJs on clinical examination one month after the injection. In the pre-injection, unilateral or bilateral TMJ dislocations were observed on MRIs in all patients. One month after the injection, TMJ dislocations were not observed in MRI evaluation of any patients. A significant structural change that caused by ABI was not observed. Conclusion : The procedure was easy to perform and it caused no foreign body reaction. However, it was unclear how the procedure prevented the dislocation.
