A Closer Look at Fibrous Dysplasia Femur Fracture Five-year Follow-up: A Unique Case.

Introduction: Fibrous dysplasia (FD) is a benign skeletal disorder characterized by the replacement of normal bone tissue with disorganized fibrous tissue. Fractures are a significant complication of FD, particularly in the proximal femur, where deformities such as Shepherd's crook deformity can increase the risk.

Case Report: We present a case study of a 44-year-old male with unilateral monostotic FD, Shepherd's crook deformity, and a pathological femoral shaft fracture. The initial surgical approach involved valgus osteotomy, dynamic condylar screw (DCS) fixation, and multiple osteotomies of the femoral shaft. However, the patient experienced a refracture and implant failure, necessitating a second surgical intervention with a double-angled DCS and additional fixation. Post-operative follow-up revealed successful bone union and deformity correction, although a limb length discrepancy was noted.

Conclusion: This case highlights the challenges in managing FD-related fractures and the importance of addressing deformities and achieving optimal alignment. Individualized treatment approaches, careful implant selection, and post-operative rehabilitation are crucial for successful outcomes in FD-associated fractures.
