Background: The proximal femur is one of the most common sites involved by fibrous dysplasia. In cases with mild deformity that does not require corrective surgery, occasional patients suffer sustained pain because of repeated microfractures. This study aimed to clarify the outcomes of surgery with autogenous fibular cortical strut grafting and compression hip screw fixation.
Methods: Since 2002, eight consecutive patients (nine hips) with femoral neck fibrous dysplasia without severe deformity were prospectively treated with autogenous fibular strut grafting and compression hip screw fixation.
Results: Mean age of patients was 35 years. Mean follow-up of patients after surgery was 75 months. Most of the patients could walk with full weight-bearing 2 weeks after surgery. Functional score of lower extremity was significantly improved from 65 % to 95 % (P = 0.001). Femoral neck angle was increased from 127 to 130. Donor site of strut cortical fibula showed good regeneration with β-tricalcium phosphate.
Conclusions: Autogenous fibular cortical strut grafting and compression hip screw fixation achieved good post-operative function and provided an early return to work for adult patients with fibrous dysplasia of the femoral neck with mild but prolonged symptoms. Morbidity in the donor site of fibula strut is minimal with the use of β-tricalcium phosphate.

Objective: To determine the utility of a triangular margin as an imaging diagnostic feature for fibrous dysplasia.
Materials And Methods: We retrospectively reviewed all surgically biopsied or managed benign and malignant bone tumors by a single orthopedic oncologist over 19 years (2003 to 2022). A musculoskeletal radiologist and an orthopedic oncologist, both with >10 years of experience, retrospectively evaluated all imaging in consensus.

Ossifying fibroma (OF) is a rare, benign fibro-osseous neoplasm that primarily originates from membranous bones. While most frequently documented in equines, OF has also been reported in other species, including dogs, though it remains uncommon. The condition poses significant diagnostic challenges due to its ambiguous presentation, often requiring differentiation from other benign and malignant intraosseous lesions.

Ossifying fibroma (OF) is a slow-growing, expansive, and benign fibro-osseous neoplasm that is rare in cattle. It mainly affects the craniofacial bones, especially the mandible. Here, we report 2 cases of mandibular OF in Nelore and mixed-breed steers with enlarged masses in the rostral portion of the mandible.

Background: Fibrous dysplasia (FD) is the most common benign tumor of the ribs, with surgical resection being the preferred treatment modality for rib FD, leading to enhanced quality of life and favorable outcomes. The complexity of surgical intervention varies depending on the location of costal FD, presenting challenges for both open surgical and thoracoscopic approaches. In this study, we present a novel technique for three-port robotic-assisted costectomy utilizing a Gigli saw, detailing our initial findings and outcomes.

Fibro-osseous tumors of the craniofacial bones are a heterogeneous group of lesions comprising cemento-osseous dysplasia (COD), cemento-ossifying fibroma (COF), juvenile trabecular ossifying fibroma (JTOF), psammomatoid ossifying fibroma (PsOF), fibrous dysplasia (FD), and low-grade osteosarcoma (LGOS) with overlapping clinicopathological features. However, their clinical behavior and treatment differ significantly, underlining the need for accurate diagnosis. Molecular diagnostic markers exist for subsets of these tumors, including GNAS mutations in FD, SATB2 fusions in PsOF, mutations involving the RAS-MAPK signaling pathway in COD, and MDM2 amplification in LGOS.
