Phosphaturic Mesenchymal Tumor-induced Osteomalacia Masquerading as an Orthopedic Polytrauma Patient: A Case Report and Review of the Literature.

Introduction: Phosphaturic mesenchymal tumor (PMT) is a rare benign tumor (500 cases to date) that can present in combination with a paraneoplastic syndrome called tumor-induced osteomalacia (TIO). To the best of our knowledge, it is the first case to date that presented as an orthopedic trauma patient.

Case Report: This is a case of a 61-year-old male who initially presented as a polytrauma patient, but further investigation revealed a PMT causing TIO.

Short-term Clinical Outcomes of Unexpected Culture-positive Cutibacterium acnes (Formerly Propionibacterium acnes) in Open Orthopaedic Surgery.

Introduction: The clinical significance and treatment recommendations for an unexpected positive Cutibacterium acnes (C acnes) culture remain unclear. The purpose of our study was to evaluate the clinical effect of a C acnes positive culture in patients undergoing open orthopaedic surgery.

Methods: Patients with a minimum of one positive C acnes intraoperative culture were retrospectively reviewed over a 7-year period.

Correction to: Early postoperative compilations of bone filling in curettage defects.

In the original publication of this article [1], there was a mistake in Figure 2. Figure 2a and Fig 2c should be swapped. The revised Figure 2 is shown below.

Early postoperative compilations of bone filling in curettage defects.

Background: Curettage is widely used in orthopedic oncology; the defect created frequently requires filling for mechanical and functional stability for the bones and adjacent joint. Allograft, bone graft substitute, and polymethyl methacrylate (PMMA) are the most common substances used each with their benefits and drawbacks. The aim of the study is to show that good functional result can be achieved with curettage and bone filler, regardless of type.

Proximal femoral reconstruction with a constrained acetabulum in oncologic patients.

Metallic endoprostheses are used for oncological reconstruction around the proximal femur and hip joint. Common modes of failure with hemiarthroplasty or standard hip arthroplasty after proximal femoral replacement include dislocation, late hip pain, and infection. The authors reviewed hospital records to identify patients undergoing constrained tripolar hip arthroplasty for oncological reasons between 2002 and 2012.

Giant cell tumor of bone in childhood: clinical aspects and novel therapeutic targets.

Giant cell tumor of bone (GCTB) is a rare primary bone tumor that primarily affects young adults, but can be seen in children. The primary modality of treatment is surgical resection; however, this is not always possible given the location and extent of the neoplasm. Recent developments in the understanding of the underlying molecular pathogenesis of disease have pointed to interactions between the stromal component producing receptor activator of nuclear factor-kappaB (RANK) and RANK-ligand (RANKL) causing the formation of osteoclast-like giant cells that drive bone destruction.

Limb-sparing surgery for distal femoral and proximal tibial bone lesions: imaging findings with intraoperative correlation.

Objective: Our purpose is to present normal and abnormal imaging findings associated with endoprosthetic reconstruction after limb-salvage surgery.

Conclusion: Endoprosthetic reconstruction varies with the location and size of the tumor, implant designs, and complications. Radiologists need to be aware of associated imaging findings seen in postoperative infection, tumor recurrence, and hardware failure.

Thermal ablation of osteoid osteoma: overview and step-by-step guide.

Osteoid osteoma is a small, benign but painful lesion with specific clinical and imaging characteristics. Computed tomography is the imaging modality of choice for visualization of the nidus and for treatment planning. Complete surgical excision of the nidus is curative, providing symptomatic relief, and is the traditionally preferred treatment.

Grading system for gunshot injuries to the femoral diaphysis in civilians.

One hundred patients had surgical treatment for a gunshot injury to the femur at the authors' hospital. Each injury was classified (Grade 1-3) based on clinical and radiographic signs of deep soft tissue necrosis. All patients were followed up for a minimum of 6 months (average, 18 months; range, 6 months-72 months).
