The Curious Case of the Flying Femoral Head - A Neck of Femur Fracture-Dislocation with Intrapelvic Lie of the Fractured Femoral Head.

Abstract

Hip dislocations are mainly high-energy injuries which generally occur posteriorly. The anterior dislocations of the hip are rare and this dislocation coupled with a neck of femur fracture is very less likely. This article presents a rare and challenging case of a 43-year-old chronic alcoholic man with an anterior hip dislocation and ipsilateral neck of femur fracture. The patient's history revealed a seemingly trivial domestic fall, but on examination, he exhibited severe pain, limb shortening, and external rotation in the left hip joint. Radiographic assessments initially suggested a posterior femoral head dislocation, but a subsequent computed tomography scan revealed an unusual scenario - the fractured femoral head had displaced anteriorly, traversing over the iliac wing, and settling in the pelvic cavity. Discussion of this unique case explores the infrequent association of anterior traumatic hip dislocations with femoral neck fractures. Prognosis in such cases is generally poor, with considerations for factors such as time to surgery, surgical findings, and patient age playing a crucial role in determining the optimal treatment strategy. The article delves into the challenges posed by the presented case, emphasizing the importance of appropriate diagnosis and surgical planning in managing these complex injuries. The rarity of the presented injury, coupled with the unexpected clinical course following surgery, underscores the importance of maintaining a high index of suspicion for unusual presentations, even in seemingly minor traumas. This article contributes valuable insights into the diagnosis, surgical management, and challenges associated with the rare combination of anterior hip dislocation and ipsilateral neck of femur fracture.
