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.

Purpose: To evaluate the clinical feature and the results of the treatment of Lisfranc joint fracture/dislocation with limited open reduction, pin fixation and Ilizarov external fixation. Materials and Methods: From June 2001 to May 2003, six patients with Lisfranc fracture/dislocation were treated. The average periods of follow-up was 23 months. After limited open reduction on the second tarso-metatarsal joint, we performed pin fixation of the above joint. On the other Lisfranc joint fracture/dislocation, closed reduction and the application of Ilizarov external fixator was done. This rigid system produced the early partial weight bearing and joint motion of the injured foot and ankle joint. The parameters used were radiographic evaluation, patient's clinical assesment and the AOFAS midfoot score. Results: We used the Myerson's criterier to evaluate the radiographic result. All cases could be achieved more than nearly anatomical reduction. Three cases of excellent and 3 cases of good result could be obtained in the evaluation of the patient's clinical assesment. The average AOFAS midfoot score was 87.2 ($76{\sim}95$) points. Conclusion: The treatment using Ilizarov external fixation on Lisfranc joint fracture/dislocation can be another useful method.

Bosworth fracture-dislocation of ankle is very rare, occurred by eversion and external rotation force. It is known as irreducible fracture by closed method. Also, compartment syndrome after ankle fracture are exceedingly rare. There are only a few reported cases of compartment syndrome after ankle fracture and compartment syndrome are involved commonly deep posterior compartment. We present a case in which a patient had a Bosworth fracturedislocation of the ankle underwent open reduction with internal fixation and subsequently occurred an anterior compartment syndrome of the leg.

Isolated fracture dislocation of the tarsal navicular bone is extremely rare. The mechanism of injury of this fracture dislocation is known as a horizontal or axial load on plantar flexed foot. Closed or open reduction is recommended for displaced navicular fracture. We report one case of isolated fracture dislocation of the tarsal navicular which was treated with closed reduction and percutaneous K-wire fixation.

Ankle injury is a very common injury. Especially it is the most commonly injured site in cases sports injuries. However, severe open ankle sprain (SOAS), defined as the tearing of the skin over the torn ligament in the ankle, is extremely rare, and no cases have been reported in Korea. In our center, we encountered a patient with a severe ankle open sprain, so we report and discuss that case.

The midtarsal joint is composed of the talonavicular and calcaneocuboid joints. It is also known as the Chopart joint. Midtarsal joint fracture and dislocation are relatively rare and frequently missed or misdiagnosed. A proper understanding about the anatomy of the midtarsal joint is an essential part in comprehending the mechanism of injury and rationale for treatment. Anatomical reduction of midtarsal joint with correction of the column in length and shape are important; however, it is technically challenging and may require open procedure. Herein, we described a case of initial open reduction and internal fixation for midtarsal joint fracture and dislocation with a brief literature review.

Calcaneus fracture with a subtalar dislocation are extremely rare. A case of a joint depression type calcaneus fracture with a lateral dislocation of the calcaneal posterior facet and tuberosity is presented. We treated it with open reduction and internal fixation with Steinmann pins and K-wires through limited posterior approach and obtained satisfactory radiographic and clinical outcome.

Traumatic dislocation of the peroneus longus tendon is an often unrecognized injury which has been reported to occur most commonly during sports activity. Most acute cases with early detection can be treated by simple repair of the tendon or retinaculum using one of several procedures available. Accurate treatment through a comprehensive evaluation of the ankle injury prevents suboptimal and sometimes unrecorrectable outcomes. The authors experienced concomitantly the peroneus longus tendon dislocation associated with a trimalleolar fracture of the ankle. We report this case a brief review of the literature.

Chopart joint fracture and dislocation are rare injuries compared with other joint injuries with various clinical manifestations. Moreover, there is a lack of knowledge of the radiological findings of the joints, and thus, the extent of joint ligament damage may be underestimated, leading to improper treatment. This paper reports three cases of Chopart joint injury and seeks to reconsider the importance of Chopart joint evaluation and treatment.

Tarsometatarsal fracture-dislocation is uncommon but severe lesion. Since this lesion is sometimes difficult to recognize by roentgenography, it is easily overlooked. Three patients were treated with open reduction and internal fixation with 3.5 mm cannulated screw and K-wire, two had treatment with open reduction and internal fixation with 3.5 mm cannulated screw only and two had treatment with dosed reduction and short leg cast only between January 1994 and May 1996. The duration of follow-up ranged from twelve to twenty-nine months after the diagnosis. Results were assessed by a subjective questiormaire, physical examination, and radiographic analysis. Multiple fixation techniques for maintaining the reduction of tarsometatarsl joint have been introduced. We recent]y used the 3.5 mm cannulated screw for internal fixation of the tarso-first and second metatarsal fracture-dislocation. We think cannulated screw fixation has several advantages; 1. The cannulated screw fixation is more rigid than the K-wire fixation. 2. There is an decreased risk of screw breakage with early weight bearing. 3. It is possible to compress the involved joints, if necessary. There were no disability in all patients. One patient who was treated with delayed open reduction and internal fixation with 3.5 mm cannulated screw and K-wire had a radiographic mild degenerative arthritis. And one patient who was treated with dosed reduction and short leg cast had a mild metatarsus adductus. But. these two patients were symptom free. There was no correlation between the severity of the diastasis and the patient s functional result.
