Objective : The clinic study or report about Oriental Medical treatment about osteonecrosis is very insufficient. Therefore, we report a case about a sequela of operation of talus osteonecrosis treated by Oriental Medical treatments. Methods : The patient was managed by bee venom and Carthami Flos Herbal-Acupuncture, Sa-am and body acupucture, moxibustion, physical theraphy and herbal medicine. We evaluated the patient through Visual Analogue Scale(VAS). Results : After 25 days of treatment, the patient showed that clinical symptoms was decreased and VAS changed from 10 to 2. Conclusion : In this case, Oriental Medical treatments for a sequela of operation of talus osteonecrosis was effective. But further studies are required to confirm the effect of these methods.

A vascular necrosis of the talus has frequently been reported following trauma because talus has no muscle insertions, sixty percent of the surface of the talus is covered by hyaline cartilage, takes only a small area for entrance of a blood supply. Osteonecrosis is also associated with a variety of nontraumatic disorders. There are many indications for steroid usage, patient with rheumatoid arthritis, systemic lupus erythematosus, chronic obstructive pulmonary disease, and status- post renal or cardiac transplantation may be on long- term steroid usage, osteonecrosis may develop. A vascular necrosis of the talus secondary to chronic steroid usage is an unusual case. Delay in detection of osteonecrosis may lead to fragmentation and collapse of the talar body. When pain on range of motion is present and conservative treatment have been exhausted, surgical treatment is indicated, that is, fusion of the ankle joint. However it is important that conservative treatment may prevent its various sequelae with early diagnosis because steroid - treated patients have a more operative risk and increased risk for postoperative infection. We report a rare case of corticosteroid induced avascular necrosis of talus after cardiac transplantation.

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.

Purpose: The purpose of this study was to evaluate the radiological and clinical outcomes of tibiotalocalcaneal arthrodesis using retrograde compressive intramedullary nail for patients with complex hindfoot problems, including Charcot arthropathy, osteonecrosis of talus, combined arthritis of the ankle and subtalar joint, failure of previous ankle arthrodesis, and failed total ankle arthroplasty. Materials and Methods: Eighteen consecutive patients (10 men and 8 women) with an average age of 54 years (range, 42~72 years) underwent tibiotalocalcaneal arthrodesis using retrograde compressive intramedullary nail fixation. The mean duration of follow-up was 16 months (range, 12~23 months). Radiological evaluation included assessment of the union status of ankle and subtalar joints. Clinical evaluations included visual analogue scale (VAS) for pain and patient satisfaction, and postoperative complications were analyzed. Results: Radiological union was achieved in 14 ankle joints (77%) and 16 subtalar joints (88%) at an average of 16 weeks (range, 14~40 weeks) and 14 weeks (range, 12~24 weeks), respectively. The preoperative VAS were 4.6 (range, 4~8) at rest and 8.2 (range, 7~10) during walking, and the postoperative VAS were 2.2 (range, 0~3) and 4.6 (range, 4~6), respectively (p<0.05). There were 6 nonunions (4 ankle joints and 2 subtalar joints), 3 tibia fractures, 2 delayed union of ankle joints, and 2 breakage of the implant. Conclusion: Tibiotalocalcaneal arthrodesis using retrograde compressive intramedullary nail may be considered as a viable option in patients with complex hindfoot problems.
