Stages of vegetation development on talus area were studied to examine temporal changes in species composition and vegetation structure, and to elucidate the mechanism of early patch formation. While ground coverage of lichens, which may form substrate for moss colonization and mitigate the heat-stress on rocks, decreased gradully, coverage of mosses increased slightly during primary succession. Ecological role of mossess related with water retention in community may be very important not only at pioneer stage but also at later stages because of little soil development on this talus area. Species diversity and species richness increased during the early stages of succession. Parthenocis년 tricuspidata and Sorbaria sorbifolia var. stellipa dominated in liana stage, Ulmus davidiana for. suberosa and Lindera obtusiloba in shrub stage, and Fraxinus rhynchophylla and Actinidia arguta in subtree stage, however, was composed of mixed forest of several tree species. U. davidiana for. suberosa, L. obtusiloba, Securinega suffruticosa and Rhus chinensis were relatively important woody species in early patch forming process. The results, however, suggested that early establishment on talus area might be strongly associated with chance for safe-site because both pioneer species and later species could take part in early patch forming process.

Arthroscopic treatment has been reported to provide effective improvement of ankle function when used in treatment of small osteochondral lesion of talus; however, favorable long-term results have been less predictable for large osteochondral lesion of talus. In cases in which primary arthroscopic treatment fails, the decision regarding which subsequent technique to choose has become increasingly difficult, as good clinical outcomes may be unlikely for such patients irrespective of the surgical technique used. Redomicrofracture should be used judiciously for treatment of osteochondral lesion of talus in which arthroscopic treatment has failed.

Nonunion and avascular necrosis are well-recognized complications of severe ankle injury especially aftrer talar neck fracture. The treatment of avascular necrosis is controversial and methods of treatment are limited. Many modalities have been introduced for the treatment of avascular necrosis of talus. The prolonged non-weight bearing for 2~3 years is not practical but also is occasionally complicated by late segmental collapse. Operative treatment includes tibiotalar arthrodesis and talectomy with tibiocalcaneal arthrodesis, but arthrodesis in patients with talar avascular necrosis is technically demanding and cause stiff, immobile foot and relatively high failure rate was reported. It is desirable to preserve their original joint if possible. Vascularized fibular grafting has been reported as a joint preserving treatment option for osteonecrosis of the hip but has not been described for the ankle. The authors applied free vascularized fibular grafts for 3 cases of avascular necrosis of talus. We observed evidences of revascularization of necrotic talar body and progression of fracture healing and obtained satisfactory results at mean 8 months of follow-up. Vascularized fibular grafting is one of the better alternatives for treating avascular necrosis of talus. It is expected that vascularized fibular grafting can prevent the necrotic talar dome from progressing to collapse and promote directly restored vascularization and new bone formation.

Chondroblastoma is a rare benign tumor that produces giant cells and cartilage matrix. The tumor occurs in people between 10 and 25 years with slightly higher incidence in males. The condition occurs in the proximal epiphysis of the tibia and humerus, distal epiphysis of the femur, but its occurrence in the talus is relatively rare, accounting for 4% of the total number of chondroblastoma cases. Chondroblastoma is often misdiagnosed as a primary aneurysmal bone cyst, giant cell tumor, chondromyxoid, and lesion of a secondary aneurysmal bone cyst by fibrous dysplasia. The most commonly used surgical method for chondroblastoma is broad curettage with bone grafting. In general, an aneurysmal bone cyst is associated with a second degree chondroblastoma, which is approximately 20%. Chondroblastoma of the talus and secondary aneurysmal bone cysts can be misdiagnosed as primary aneurysmal bone cysts. This paper reports a case of a young male patient with chondroblastoma of the talus, which was initially misdiagnosed as an aneurysmal bone cyst with involvement of the talo-navicular joint.

Objective: This is the result of a study on patients with osteochondritis dissecans (OCD) of the talus whose pain was improved by Gamchobuja-tang (GBT). Methods: The patient took GBT for 46 days. We observed the progress of symptoms, patient compliances and side effects. Quality of life related to pain was quantified through the SF-36 and AQoL-6D questionnaires. The degree of pain in the talus and ankle areas was quantified using VAS and observed through the symptoms and frequency complained of by the patient. Results: According to the DPIDS, the patient was diagnosed with the 175 provision in Taeyangbing chestbind (大陽病 結胸). As a result, SF-36 score increased from 36 points to 74 points, and the AQoL-6D score increased from 74 points to 104 points. The visual analogue scale (VAS) of ankle pain lowered from 9 to 2. The number of days with VAS levels 1 also increased. Conclusions: Gamchobuja-tang is effective in reducing pain in the talus area caused by osteochondritis dissecans..

Brodie abscess is a localized form of chronic or subacute osteomyelitis that occurs most often in the long bones of the lower extremities of young adults. Involvement of the flat or small bones is less common. And there is no report of Brodie abscess which has two different lesion. We report a case of Brodie abscess of talus and distal tibia.

Concomitant fracture of medial tubercle of posterior process and lateral process of the talus has not been reported in Korean literature. Association between fracture of lateral and posterior process of talus is not clear. We treated with open reduction and screw fixation in fracture of lateral process and with excision of fragment of posteromedial tubercle of posterior process with satisfying result.

Talus fracture is less common than most fractures, and bilateral talar neck fracture is extremely rare. Complications associated with talus fractures are generally deemed common because of the anatomical characteristics of the talus, but few reports have described the methods of treating such complications and the results of bilateral talar neck fracture. We report here a case of bilateral Hawkins type II talar neck fracture that had good clinical results without complications after early surgical treatment.

Microfracture as a reparative strategy is the treatment of choice for an osteochondral lesion of talus. Although the results of microfracture are generally excellent, at least 30% of patients who received microfracture have acute or chronic ankle pain with several or unknown causes. The most important factor for unsatisfactory outcome after microfracture is the size of the lesion. For failed osteochondral lesion of talus, the second options are autologous osteochondral graft, autologous chondrocyte implantation, or re-microfracture. In this article, we present the autologous chondrocyte implantation as a second procedure for failed microfracture and compare its clinical outcome with other methods based on a literature review.

Despite the increasing number of osteochondral lesions of the talus, there are a lack of definite evidence-based treatment protocols. Several types of treatments are available, each having their advantages and disadvantages. First-line therapy consists of well-conducted conservative treatment. Surgical treatment is the second choice. Treatments are chosen based on the size of the lesion, location, chronicity, and the condition of the neighboring cartilage. This article reviews the current updates in the treatment of osteochondral lesions of the talus to help clinicians use the available treatment strategies more efficiently.
