Background: Fracture of Talus is a relatively rare disease, and treatment outcome is not always predictable. The aim of this study is to report our experience with the surgical treatment of fractures of talar body and neck.Methods: In a retrospective study, 16 patients (12 men, 4 women) with body and neck fractures of Talus were evaluated in a teaching hospital in Mashhad. The mean age was 24.8 years (15-50 years). The fracture pattern, mechanism of trauma, associated injuries, union rate, avascular necrosis, pain and disability were evaluated in mean follow-up period of 18 months (12-24 months).Results: All the patients showed union during the follow-up. Five patients (31%) had avascular necrosis. The mean for Hawkins score system was 8.25. All the cases showed evidence of pain and some disability at the end of study.Conclusion: Talus fracture is a disabling injury and high incidence of pain and activity restriction should always be expected, even with surgical treatment.

A 7-year-old boy was referred to us with a 3-month history of swelling and pain on his left ankle. On laboratory evaluation, he only had an elevated erythrocyte sedimentation rate. X-ray showed an extensive lytic lesion of the Talus bone. Chest roentgenogram was normal. The Mantuex skin test was negative. Histological examination of the biopsy tissue showed granuloma and caseating necrosis of tuberculosis. Talectomy with 6 months of antituberculous chemotheraphy resulted in a good clinical outcome.

Case: Isolated Talus osteomyelitis caused by Koch's bacillus (BK) is extremely rare. In this paper we report an isolated Talus bone tuberculosis in a 52 year-old man who presented a 2-month history of swelling, pain and functional disability of his right ankle. Surgical bone curetting and histological examination showed granuloma with central caseating necrosis. Acid fast stain and PCR examination of the sample showed Koch's bacillus which confirms TB of the Talus.

Introduction: Primary non-Hodgkin’s lymphoma of the bone (PLB) represents about 3% - 5% of all extranodal non-Hodgkin’s lymphoma (NHL) cases and 7% of primary bone tumors. It may occur at any age. The peak incidence for PLB is in the fifth and sixth decades of life, and it has a slight male predominance. The most commonly affected sites are the long bones. A palpable mass due to soft tissue extension of the bony disease is seen in almost half of all cases.Case Presentation: We report the case of an NHL (diffuse large B-cell lymphoma) in the Talus bone of a 17-year-old boy who was referred to our center in 2011 - 2012, which had an odd presentation. The patient’s first diagnosis was a simple ankle sprain, and he underwent conservative treatment. Given the patient’s deteriorating symptoms, further paraclinical evaluations were conducted, and fracture of the Talus was diagnosed, which was thought to be a cause of further osteonecrosis. Finally, because of lack of pain relief and due to MRI images, the suspicion of malignancy was raised. Open biopsy of the Talus showed NHL (diffuse large B-cell lymphoma).Conclusions: The present case is interesting because it expresses how such lesions can be met with diagnostic confusion.

Osteoid osteoma is benign bone tumor, in which Talus bone involvement is rare. This case was a 17 year old man with a right ankle pain and reduced range of motion since one year ago. Following clinical evaluation and radiological studies (X-ray, CT scan, and MRI), a bone tumor was detected in the Talus with a possible diagnosis of Osteoid osteoma. The patient was operated with ankle anterior approach and the tumor was resected from the site. The patient was discharged after two days. The patient's pain was eliminated after surgery. Ankle movements are back after two months. Due to the rare nature of the disease and clinical diagnostic problems and its unusual radiographic manifestations, osteoid osteoma in chronic ankle pain in young patients, is included in the list of differential diagnosis.

Background: The most common method of treatment for vertical Talus is the extensive soft tissue release. A minimally-invasive method based on Dobb's serial casting (Reverse Ponseti) was introduced 15 years ago and has yielded significant results. The aim of this study was to investigate and compares the midterm results of Casting with the extensive soft tissue release method. Methods: 12 patients with vertical Talus were included in a prospective study, 6 patients with 10 feet were treated with reverse ponseti, and 6 other patients with 10 feet with externsive soft tissue release. In an 18-24 months follow-up the results were compared together, using ankle range of motion, oxford questionnaire, and radiographic measurements. Results: The mean range of ankle motion was comparable in the two groups (p=0. 35), the oxford questionnaire score was not statistically different between the two groups (p=0. 876). Conclusion: With the comparable results between the ''reverse-ponseti'' casting land extensive surgical releases in this mid-term study, the casting technique is recommended because of its lower cost and non-invasive nature.
