Pipkin fracture dislocation with ipsilateral lateral collateral ligament and medial collateral ligament avulsion injury-a rare case report

Pipkin fractures are complex femoral head fractures typically associated with posterior hip dislocation. Concomitant injuries of the knee ligaments, especially involving both the medial collateral ligament (MCL) and lateral collateral ligament (LCL), are exceedingly rare. Early diagnosis and coordinated management are critical to preserving joint function and preventing long-term complications such as osteonecrosis or instability. We report an unusual case of a high-energy trauma resulting in a Pipkin type II fracture-dislocation with ipsilateral LCL and MCL avulsion injuries.
