Use of computer-assisted hexapod external fixators for complex foot and ankle reconstructions - An analysis of functional outcomes and complications.

Introduction: Foot and ankle pathology can often require complex surgical reconstruction. Until recently, circular external fixators such as the Ilizarov frame have proven to be useful, yet they fall short when progressive, precise corrections are required. Computer-assisted hexapod external fixators seek to address many of the shortfalls of traditional circular fixators.

Our systematic review sought to assess overall survival based on histology and surgical intervention.

Pseudolesions involving bone and soft tissue regarding orthopedic oncology.

Pseudolesions in bone and muscle are encountered mostly incidentally in routine imaging studies, especially due to the recent advancements on many different imaging modalities. These lesions can be categorized into the following categories: normal variants; congenital; iatrogenic; degenerative; and postoperative. In this review, we discuss the many different radiological characteristics of musculoskeletal pseudolesions that appear on imaging, which can prevent non-essential additional studies.

Background: The low incidence of myxofibrosarcoma (MFS) makes high power studies difficult to perform. Demographic and prognostic factors for MFS and how they differ from all extremity soft tissue sarcomas (STS) are not well understood. The purpose of this study was to characterize a large cohort of patients with MFS and evaluate epidemiologic and survival factors when compared to all STS.

Is Unplanned Excision of Soft Tissue Sarcomas Associated with Worse Oncological Outcomes?-A Systematic Review and Meta-Analysis.

Background: Soft tissue sarcomas are a group of rare neoplasms which can be mistaken for benign masses and be excised in a non-oncologic fashion (unplanned excision). Whether unplanned excision (UE) is associated with worse outcomes is highly debated due to conflicting evidence.

Methods: We performed a systematic review and meta-analysis following PRISMA guidelines.

Risk Factors and Management of Prosthetic Joint Infections in Megaprostheses-A Review of the Literature.

Prosthetic joint infection (PJI) is the most common mode of failure of megaprostheses, yet the literature on the topic is scarce, and studies report conflicting data regarding the optimal treatment strategy. Patients with megaprostheses PJI are often immunosuppressed, and surgeons must balance the trade-off between treatment efficacy and morbidity associated with the surgery aiming for infection eradication. Our review on megaprostheses PJI focuses on two axes: (1) risk factors and preventative strategies; and (2) surgical strategies to manage this condition.

Background: Foot and ankle soft tissue sarcomas (STSs) are rare neoplasms associated with a high risk of local recurrence and metastasis. Although amputation is often performed, its impact on prognosis remains unknown. The aims of our systematic review were identifying risk factors for (1) disease-specific death, (2) local recurrence, (3) metastasis, and assessing (4) whether the type of surgery (amputation or limb-salvage) affected disease-specific survival.

Unusual lipid poor spindle cell lipoma.

Spindle cell lipomas (SCLs) containing minimal fat are rare and can be diagnostically challenging due to their similar radiographic appearance to other benign and malignant tumours. SCLs are benign lipomatous tumours that typically occur in middle aged to elderly men as slow-growing, painless masses in the subcutaneous tissue of the posterior neck, shoulders or back. However, rarely these tumours can arise in unusual locations such as the lower extremities.

Subtrochanteric nonunion after intramedullary nailing due to pathological fracture: proximal femoral replacement as a salvage approach.

Purpose: To assess proximal femoral replacement as a treatment solution for nonunion of pathologic subtrochanteric fractures after cephalomedullary nailing in patients with pathological fracture and previously irradiated bone.

Methods: Retrospective review of five patients with pathological subtrochanteric femoral fractures that were treated with cephalomedullary nailing and developed a nonunion, which was revised with conversion to a proximal endoprosthetic replacement.

Results: All five patients had previously been treated with radiation.

PET-CT in the Evaluation of Neoadjuvant/Adjuvant Treatment Response of Soft-tissue Sarcomas: A Comprehensive Review of the Literature.

➢: In soft-tissue sarcomas (STSs), the use of positron emission tomography-computed tomography (PET-CT) through a standardized uptake value reduction rate correlates well with histopathological response to neoadjuvant treatment and survival.

➢: PET-CT has shown a better sensitivity to diagnose systemic involvement compared with magnetic resonance imaging and CT; therefore, it has an important role in detecting recurrent systemic disease. However, delaying the use of PET-CT scan, to differentiate tumor recurrence from benign fluorodeoxyglucose uptake changes after surgical treatment and radiotherapy, is essential.

Benign Bone Lesions Found in Childhood.

Benign bone tumors are a wide variety of usually asymptomatic neoplasms, which in most cases are diagnosed due to secondary causes. As such, their real incidence is unknown. In the majority of cases, plain radiographs are enough for diagnosis; more advanced imaging, such as CT scan or MRI is sometimes performed for equivocal lesions.

Management of Long Bones Metastatic Disease: Concepts That We All Know but Not Always Remember.

Bones are the third most common site of metastatic disease. Treatment is rarely curative; rather, it seeks to control disease progression and palliate symptoms. Imaging evaluation of a patient with symptoms of metastatic bone disease should begin with plain X-rays.
