RESUMEN
INTRODUCTION: Femoral head fractures are rare injury compared to other hip pathologies and often associated with posterior hip dislocation. Such fractures are often fraught with complications even after successful surgical fixation. Pipkin described a classification system for such fractures, dividing them into four types, of which Type III (31C.3) fractures are associated with femoral neck fractures. These fractures are the least common and often associated with the worst outcomes. CASE REPORT: We report a rare case of Pipkin Type III fracture after attempted hip relocation and review literature on this topic. A 35-year-old female sustained a right posterior hip dislocation with femoral head fracture following a fall. After attempts of manipulation and reduction, she sustained an iatrogenic right femoral neck fracture resulting in a Pipkin III femoral head fracture. Open reduction and reduction of fracture achieved through headless compression screw of femoral head and cortical screws of femoral neck. Four months after surgery, the patient under osteonecrosis of the femoral head and subsequently required conversion to a right total hip arthroplasty. CONCLUSION: Femoral head fractures have serious sequelae and should be treated with caution. A high index of suspicion is required; hence, if clinically suspicious, proper imaging is paramount to prevent iatrogenic injury to the femoral neck resulting in subsequent avascular necrosis.
