Background: The purpose of this study was to identify the clinical and radiological outcomes of hook plate fixation for lateral end fracture of the clavicle and acromioclavicular dislocation. Methods: There were a total of 20 cases with lateral end fracture of the clavicle and 16 cases with acromioclavicular dislocation. All patients were evaluated for range of motion, functional score by using Constant score, and American Shoulder and Elbow Surgeons shoulder index at just before implant removal and at final follow-up. Coracoclavicular distance was measured in acromioclavicular dislocation and bony union was evaluated in the lateral end fracture of the clavicle. Results: The clinical outcomes and range of motion were increased at the final follow-up compared with just before implant removal in both the lateral end fracture of the clavicle and acromioclavicular dislocation. In acromioclavicular dislocation, all cases-except one-showed maintenance of reduction after implant removal. Moreover, in the lateral end fracture of the clavicle, all cases-except one-showed bony union. Conclusions: Hook plate fixation in the lateral end fracture of the clavicle and acromioclavicular dislocation resulted in good clinical and radiological results.

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.

Purpose Displaced lateral end fracture of clavicle and acromioclavicular dislocation type Ⅲ∼Ⅵ may be required surgical treatment. Material and Methods : From May 1998 to March 2001, we operated with Welter plate with minimal incision by one surgeon. Immediately, pendulum and passive exercise was initiated after surgery. The shoulder function was evaluated using UCLA score. Average follow up was on 28(12∼45) months. Results : All 11 patients were regained satisfactory function. Average UCLA score was 31.9(29~35) at last follow up. Conclusion . The merit of Welter plate fixation with minimal incision is simple technique, reduced surgical time, smaller scar than large plate, strong fixation, early exercise, reduced implant failure. The disadvantage is expensive, skin irritatatation by long hook. But Welter plate fixation with minimal incision is a good method of internal fixation and excellent clinical result in surgical treatment of type H displaced lateral end fracture of the clavicle and type Ⅲ∼Ⅵ acromioclavicular dislocation.

Purpose: This study seeks to address the results of percutaneous lateral release and medial reefing for patients with recurrent patellar dislocation. Materials and Methods: This paper focuses on 27 cases from 25 patients who had a surgical operation at our hospital in a span of eight years and six months from the time of December 1996 to May 2005. The subjects consist of 11 males and 14 females, and their average age was 22.2 years old. All the patients had their trauma history, and the average frequency of dislocation before surgery was 11.5 times. Results: The congruence angle before operation was 23.3 degree on the average, while the lateral patellofemoral angle was -5.7 degree on average. However, the congruence angle after surgery came to -2.4 degree, while the lateral patellofemoral angle recovered to the normal range of within 11.5 degrees. Four cases showed the recurrent dislocation, and two out of those four cases had -35, -12 degrees of their lateral patellofemoral angle respectively and 59, 14 degrees of their congruence angle respectively. Conclusion: Using percutaneous lateral release with medial reefing can be considered as an effective treatment for recurrent patellar dislocation

Lateral and superior-lateral dislocations of the intact condyle are a rare complication, following traumatic insult to the mandible. We report an unusual case of a 54-year-old male patient who experienced both types of dislocations of the intact condyles with symphysis fracture following a road-traffic accident. Under general anesthesia, conventional manipulation was unsuccessful in relocating the condyles into the glenoid fossa. After applying a percutaneous traction force, using a bone traction hook placed at the sigmoid notch, the displaced intact mandibular condyles were repositioned, and the symphyseal fracture was finally reduced and fixed. The mouth opening was within normal limits, and favorable occlusion was confirmed one month postoperatively. To our knowledge, this is the first case of dislocation of both intact condyles--associated with symphysis fracture--being reduced with bone traction hook.

Purpose: To compare and analyze the outcome of primary clavicular lateral end resection method and conventional acromioclavicular (AC) joint reduction method in type III AC dislocation patients over 45 years. Materials and Methods: This study was performed on selected 24 cases of type III AC dislocation patients, over 45 years of age, operated at our hospital from 1998 to 2002. Group I consist of 12 patients who underwent primary clavicular lateral end resection methods (average age: 54.3 years$(45{\sim}72)$). Group II consist of 7 patients using Bosworth methods and 5 patients using Phemister methods (average age: 54.4 years$(45{\sim}71)$). Clinical outcome was evaluated by Weaver and Dunn method. Radiological results were compared by measuring coracoclavicular distance between normal and injured side. Results: As clinical outcome, good was 10 cases(83%); fair 2(17%) in Group I, and good 6(50%); fair 3(25%); poor 3(25%) in Group II. In contrast, the difference of coracoclavicular distance was not statistically significant between two groups before or after surgery, and last follow up. At the last follow up, there was no special correlation between the difference of coracoclavicular distance and clinical outcome. Conclusion: We considered that primary clavicular lateral end resection may be effective for prevention of arthrosis in AC joint in type III AC dislocation patients over 45 years.

Purpose: In previous study, the frequency of osteoarthritis and discomfort were high in ankle fracture-dislocation but detail results about ankle fracture-dislocation has rarely been investigated. In this study, we retrospectively analyze the outcome of the operative treatment of ankle fracture with dislocation for over-2 years follow up. Materials and Methods: There were 47 cases of ankle fracture-dislocation in our hospital from March 2007 to May 2010. We investigated 20 patients who underwent operation and were possible for over-2 years follow up. The result was estimated with the direction of dislocation, fracture type, the time of bone union and post-traumatic osteoarthritis with plain radiologic images. In clinical assessment, we statistically evaluated the function and pain through AOFAS score and Olerud & Molander scoring system. Results: By Lauge-Hansen classification, there were 13 cases(65%) of pronation-external rotation and 6 cases(30%) of supination-external rotation, 1 case(5%) of supination-adduction. AOFAS score was 85.5, and Olerud & Molander score was "excellent" in 8 cases, "good" in 5 cases, "fair" in 3 cases and "poor" in 4 cases. Postoperative complications in 4 cases revealed post-traumatic arthritis. All kinds of lateral dislocation of ankle fracture was 15 cases and the most common. Of these, all 3 cases, anterolateral dislocation showed post-traumatic osteoarthritis. Conclusion: In ankle fracture-dislocation, post-traumatic osteoarthritis occurred in 4 of 20 patient(20%). Especially, the possibility of post-traumatic osteoarthritis was more in cases of anterolateral or lateral dislocation. So, it must be needed that deliberate examination, for example, preoperative MRI and sufficient explanation to patient. Also, we have to follow up the patients carefully.

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.

Traumatic dislocation of the peroneal tendon is a rare injury. It should be distinguished from other conditions that can cause pain and disability of lateral aspect of the ankle joint. We experienced a case of chronic recurrent dislocation of the peroneal tendon, which was treated by deepening of the peroneal groove of the lateral malleolus and reattachment of the superior peroneal retinaculum. The clinical result was satisfactory.
