HighlightsSubluxation of the peroneal tendon is relatively infrequent.Subluxation of the peroneal tendon often misdiagnosed as ankle sprain.Avulsion of the superior peroneal retinaculum from is the main cause of peroneal tendon subluxation.Good outcomes can be achieved by peroneal groove deepening and retinaculum ligament repair.

IntroductionIn most cases, osteosarcoma occurs in the metaphysis of long bones such as femur, tibia, or humerus. Meanwhile, osteosarcoma of the talus is extremely rare.Presentation of caseWe presented a case of a thirty-eight-year-old male patient with osteosarcoma of the talus treatedwith limb salvage surgery. That procedure consists of wide excision as extra-articular resection“ totaltalectomy” followed by challenging reconstruction of the defect using fibular graft and followed by internal fixation and arthrodesis. We did an extraarticular resection of the talus, which consists of total talectomy and excision of the distal tibia and fibula. An ipsilateralnon vascularized fibular graft as harvested and placed in a horizontal plane to bridge the distal tibia and fibula to the navicular. The graft was fixated using 7.5mm cannulated headless screw and was followed by arthrodesis across the distal tibia and fibula to the calcaneus.DiscussionOptions for surgical treatment for osteosarcoma of the talus islimb salvage surgery. Extraarticular resection “total talectomy” and reconstruction using fibular bone grafttechnique creates a good functional outcome and no signs of local recurrence were found during one-yearfollow-upConclusionExtraarticular resection and reconstruction using fibular bone graftis a good technique for management of osteosarcoma of the talus.

Highlights Despite advances in the diagnosis and treatment of systemic lupus erythematosus (SLE), symptomatic osteonecrosis continues to be a significant comorbidity. Strategies to detect and manage early stages of osteonecrosis is necessary to prevent progression of this serious complication. We present a case of 23-year-old female diagnosed with osteonecrosis of the distal tibia and history of SLE.
