Talar osteosarcoma treated with limb-sparing surgery: a case report

Reconstruction after Talar Tumor Resection: A Systematic Review

This systematic review investigated the functional outcomes and complications of reconstruction methods after talar tumor resection. A systematic search of PubMed, Embase, and the Cochrane Central Register of Controlled Trials databases identified 156 studies, of which 20 (23 patients) were ultimately included. The mean Musculoskeletal Tumor Society scores in the groups reconstructed using tibiocalcaneal fusion (n = 17), frozen autograft (n = 1), and talar prosthesis (n = 5) were 77.6 (range 66-90), 70, and 90 (range 87-93), respectively. Regarding complications, sensory deficits were observed in one patient (6%) and venous thrombosis in two patients (12%) in the tibiocalcaneal fusion group, while osteoarthritis was observed in one patient (100%) in the frozen autograft group. No complications were observed in the talar prosthesis group. Reconstruction with talar prosthesis seems preferable to conventional tibiocalcaneal fusion after talar tumor resection because it offers better function and fewer complications. However, as this systematic review included only retrospective studies with a small number of patients, its results require re-evaluation in future randomized controlled trials with larger numbers of patients.

Treatment of Osteosarcoma of the Talus With a 3D-Printed Talar Prosthesis

A 31-year-old male was diagnosed with osteoblastic osteosarcoma of the talus. Limb-salvage surgery for talar osteosarcoma was performed by replacing the intact talus with a 3D-printed talar prosthesis made from medical-grade titanium. The prosthesis had 3 tunnels for simulating the ligaments around the talus. At the last follow-up, the functional and clinical outcomes were excellent. Our patient achieved 93% restoration of the Musculoskeletal Tumor Society functional score as well as a Toronto Extremity Salvage Score of 93 points, and there was no local recurrence or distant metastasis. A 3D-printed talar prosthesis showed excellent functional and clinical outcomes for a patient with osteosarcoma of the talus. A 3D-printed implant is a feasible option for patients with osteosarcoma of the foot.

Osteosarcoma of talus with heterotopic ossifications and lung metastases

Osteosarcoma is the most common malignant bone tumor and is known to occur mainly in the metaphyses of long bones. However, a few cases of osteosarcoma in talus have been reported in older patients. We experienced an osteosarcoma of an 80-year-old male patient with a talus which is rarely reported and evaluated disease patterns with four different imaging modalities.

Tumours of the talus - A pictorial review

BACKGROUND

Primary bone tumours of the talus are a rare entity and seldom described in the literature. Due to this, often the diagnosis and management of such cases are delayed. This study aims to describe a spectrum of lesions identified within our department and provide a pictorial review with the goal to aid radiologists in the evaluation and diagnosis of such lesions.

MATERIALS & METHODS

A retrospective study was conducted within our department, identifying all talar lesions, confirmed on histopathological and radiological diagnosis.

RESULTS

Results revealed 75 cases of talar lesions. Benign tumours formed the bulk of the lesions identified accounting for 85% of all cases. The most common benign tumour was chondroblastoma (n = 23). Malignant tumours were detected in 6 cases. Other lesions included osteomyelitis and avascular necrosis.

CONCLUSION

We present a variety of tumours and tumour-like conditions of the talus. Radiologists as well as orthopaedic surgeons need to be aware of such lesions, to prompt early diagnosis and initiate management in timely fashion.

Osteosarcoma of the talus treated with extraarticular resection " total talectomy" and reconstruction using fibular bone graft: A case report

Introduction

In 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 case

We 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.

Discussion

Options 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-up

Conclusion

Extraarticular resection and reconstruction using fibular bone graftis a good technique for management of osteosarcoma of the talus.

•

Osteosarcoma of the talus is extremely rare.The accurate diagnosis can be complicated by subtle clinical features.

•

Patients with osteosarcoma of the talus could be considered for limb salvage surgery.

•

The limb salvage surgery consists of extra-articular resection total talectomy and reconstruction with fibular graft.

Massive Chondroblastoma of the Talus: Treatment With En Bloc Talectomy and Tibiocalcaneal Arthrodesis: Long-Term Follow-up of a Case

Chondroblastomas are benign bone tumors that are usually located at epiphyseal regions of long bones, and are rarely located at the talus. The usual treatment consists of curettage and filling of the bone defect with bone either bone grafts or some other material, such as cement. The authors present a case of a massive chondroblastma of the talus, extending outside of bone boundaries and with a huge soft tissue mass and invasion of the adjacent calcaneus. Management included an en bloc talectomy through a double medial and lateral approach, and curettage and filling with cement of the calcaneal extension. Reconstruction was done by means of a tibiocalcaneal arthrodesis. At 11 years of follow-up, no tumor recurrence has occurred, and the AOFAS functional score is 83 out of 100 points.

LEVELS OF EVIDENCE

Level IV: Therapeutic.

Osteosarcoma of the talus misdiagnosed as ankle arthritis: a case report

We present a 65-year-old man with osteosarcoma of the talus that was misdiagnosed as osteoarthritis. The patient eventually underwent below-knee amputation and adjuvant chemotherapy.

Osteosarcoma of the hands and feet: a distinct clinico-pathological subgroup

Osteosarcomas of hands or feet are rare, and seemingly these cases differ in presentation and behavior compared to those in usual locations. The clinico-pathological presentation of patients with osteosarcomas of the hand or foot was studied and compared with published cases. Forty osteosarcomas were identified among 4,221 cases, representing 0.95 % of all osteosarcomas. Thirty of these were well documented. Mean age at diagnosis was 43 years (hands) and 36 years (feet) and male-female ratio was 1.2:1 and 2.0:1, respectively. In the hand, 62 % of the osteosarcomas presented in the metacarpals and 23 % in the phalanges, and only two cases occurred in the carpal bones. Distribution in the foot was tarsal bones 56 %, metatarsal bones 33 %, and phalanges 11 %.Of the cases in the hand 54 % were of high grade and of those in the foot 71 %. Survival of osteosarcomas of the hand or foot was 81 %. Only patients with high-grade osteosarcoma died of the disease. Histological grade was the only significant variable related to survival. High-grade osteosarcoma of the hand or feet should be treated similar to those in conventional sites. Osteosarcomas of hands or feet are rare and in a relative high proportion are of low grade. Survival in high-grade cases is comparable to that in conventional sites.
