The proportion of patients with end-stage ankle arthritis is increasing. The leading surgical methods for treating patients with end-stage ankle arthritis are ankle arthrodesis and total ankle arthroplasty. Ankle arthrodesis is considered the standard treatment for end-stage ankle arthritis. Many studies have been conducted on the two procedures, but it is unclear which is superior, and total ankle arthroplasty cannot be said to be a clear indication. Therefore, this review compares the advantages and disadvantages of two representative surgical methods for treating end-stage ankle arthritis.

Purpose: The fracture of talus has critical complications and results in various clinical outcomes. The purpose of this study is to evaluate clinical outcome and influence on involvement of ankle and subtalar joint. Materials and Methods: From December 1999 to December 2008, a total of 66 fractures and dislocations of talus was treated with minimal 9 months follow up period. Ankle-hindfoot scale of the American Orthopedic Foot & Ankle Society (AOFAS) was used to evaluate the clinical outcome. The complications and sequential radiologic findings were also analyzed. Results: There were 28 neck fractures, 11 lateral process fractures, 10 body fractures, 7 osteochondral fractures, 4 posteromedial tubercle fractures and 4 medial process fractures. In 38 cases, there were concomitant injuries. Ipsilateral ankle fracture, which found in 19 cases, was most common. The surgical treatment was performed in 36 cases. Mean AOFAS score was 85.5 (range, 72 to 96). In 13 of 47 cases, one or more fracture lines involving weight bearing surface were confirmed. The involvement of ankle or subtalar joint had resulted in unsatisfied outcome. Complications were developed as follows, post-traumatic arthritis in 8 cases, avascular necrosis in 3 cases, and deep infection in 2 cases. Conclusion: The involvement of ankle or subtalar joint in fractures of talus seemed to be common and to impact the clinical outcome. Meticulous consideration about that will be positively necessary.

Purpose: The purpose of this study was to assess the treatment outcomes and prognosis of Lisfranc joint fracture and dislocation according to the mechanism of injury and treatment method. Materials and Methods: Twenty six patients with Lisfranc fracture-dislocation who had been treated surgically were included in this retrospective study. The patients were divided into two groups according to mechanism of injury: direct crushing injury (16 patients) and indirect rotational or compressive injury (10 patients). The patients were also divided into three groups according to the surgical methods. The parameters used were radiographic evaluation, patients' subjective satisfaction levels, length of hospital stay, and the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score. Statistical analysis was performed. Results: The mean postoperative AOFAS midfoot score was 78.7. The mean length of stay was 39.6 days. Statistically significant differences in subjective satisfaction, AOFAS midfoot score, and length of hospital stay were observed between the two groups (p<0.05). However, no significance differences were observed between the three groups who were divided according to the different surgical methods (p>0.05). Conclusion: Mechanism of trauma and the severity of soft-tissue injury were significant prognostic factors affecting the surgical outcomes of Lisfranc joint fracture and dislocation.

Purpose: This study was designed to evaluate whether the method "Distal pulling with wire" after primary repair of Achilles tendon, can result in early restoration of ankle motion. Materials and Methods: In 14 cases of tendocalcaneus repair, the proximal stump was pulled down distally by wire and fixed the ends of wire to the transcalcaneal K - wire. We evaluated the range of motion of ankle joint at 4th, 6th, 12th week in 10 patients whom we followed up for more than 1 year. We evaluated the results of Achilles tendon repair by Hooker's criteria. Results: Range of motion of ankle joint revealed as follows. Degree of mean dorsiflexion improved - $5.1^{\circ},\;15.0^{\circ},\;22.4^{\circ}$ at 4th, 6th and 12th week respectively, while plantarflexion improved $21.5^{\circ},\;32.7^{\circ}$ and $42.3^{\circ}$ respectively. At one year follow up, seven of them had no problems in active daily life and sports activities. According to Hooker's criteria, the result rated excellent in nine, satisfactory in one. Conclusion: Early gain of ankle joint motion was possible by "Distal pulling with wire" after primary repair of Achilles tendon.

Purpose: To emphasize the importance of considering tuberculosis in atypical cases of foot and ankle by reporting clinical results of those cases. Materials and Methods: Seven cases which were diagnosed as tuberculosis around foot and ankle from March 1996 to June 2007 were included. We reviewed initial impressions, the time to be diagnosed, clinical symptoms, laboratory findings, radiological findings and the clinical results and complications. Results: We followed up at least 6 months ($6{\sim}24$ months) after surgery in all cases. Initially 2 cases had been diagnosed as cellulitis, 4 cases as chronic osteomyelitis, and 1 case as an ankle instability. Tuberculosis was diagnosed after biopsy in all cases. Mean duration of symptom was 15 months ($6{\sim}36$ months) except in infants. There were various radiologic manifestations such as osteopenia, bony erosion or destruction and cystic changes. Symptoms were relieved in all cases within 4 months with chemotherapy followed by surgical biopsy, except one ankle which had been misdiagnosed as ankle instability and joint destruction was developed after modified Brostrom surgery. Conclusion: It is important to perform a surgical biopsy for diagnosis and proper management even with a faint suspicion on tuberculosis in foot and ankle. And in case of need, when surgical biopsy is performed, curettage procedure may help to improve clinical result.

Purpose: To find out the priority of which procedure has had a better outcome both clinically and radiographically between the two groups, one is treated by primary repair and the other by modified Brostr$\ddot{o}$m's procedure, by comparing the postoperative ankle joint stability and the patient's degree of satisfaction. Material and methods: 16 cases were taken into consideration whose number of severed ligaments were at least two or more of the lateral collateral ligaments of the ankle, and also were confirmed intraoperatively. Among them, 8 cases were treated with primary repair and the other 8 cases were treated with primary repair and the other 8 cases by modified Brostr$\ddot{o}$m's procedure. Results: There was no distinguishable difference for the patient's degree of satisfaction between the two procedures above mentioned. In 3 cases treated with primary repair, functional instability was observed. In case of postoperative ankle joint stability, 7 of 8 cases treated by modified Brostr$\ddot{o}$m's procedure has revealed increased joint stability. And 3 of 8 cases which were treated by primary repair have showed postoperative residual instability. Conclusion: Actually, the severed ligament can not maintain its normal strength though several months has elapsed, and possible residual instability could be remained. Therefore, it can be expected that modified Brostr$\ddot{o}$m's procedure also would be a .good method in obtaining suitable ankle joint stability as well as subtalar joint stability because of its reinforcement using extensor retinaculum.

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.

The Lisfranc joint complex is an anatomical association of many bones and articulation, restrained by an even more complex network of ligaments, capsules, and fascia, which must work in concert to provide normal and painless motion. Careful diagnostic workup with high-quality radiographs and computed tomography of the foot are used to diagnose injuries and fractures of this complex. We have to understand the normal anatomy and injury mechanism in order to appropriately treat Lisfranc injuries. Good results have been associated with anatomic reductions of all bones, which was achieved with restoration of proper alignment.

Purpose: To evaluate the effect on clinical course of heterotopic ossification of distal tibiofibular syndesmosis after ankle fractures. Materials and Methods: From June 2001 to May 2004, we found nine cases of heterotopic ossification of distal tibiofibular syndesmosis after ankle fractures. There were 8 male patients and 1 female patient; their mean age was 42 years old. There were 6 Weber type B and 2 Weber type C fractures, and there is 1 case with posterior malleolus fracture only. Among them, 8 ankle fractures were operated. Follow up period was averaged for 14 months. We were able to review radiographs at initial injury and to review clinical menifestation and radiographs at last follow up. We used an ankle-hindfoot scoring system of AOFAS which combined symptom, function and alignment with maximum score of 100 point. Results: In all cases ankle dorsiflexion and plantarflexion were not significantly different from that of the contralateral side. The patients who had developed heterotopic ossification in distal tibiofibular syndesmosis had a similar functional score. The mean ankle-hind foot score was 94 points. Conclusion: We concluded that the heterotopic ossification of distal tibiafibular syndesmosis after ankle fractures had little effect on clinical course and range of motion of ankle joint.

We experienced a case of congenital insensitivity to pain with anhidrosis mimicking a chronic osteomyelitis of the talus, with recurrent ankle swelling and intermittent fever. He was misdiagnosed as low virulence osteomyelitis at other hospital in annual recurrence for 3 years. A Charcot joint in children is a very rare condition and diagnosis should be made in a careful approach.
