Adolescent Hip Fracture-Dislocation: Transphyseal Fracture with Posterior Dislocation of the Proximal Femoral Epiphysis: A Case Report.

CASE: A 13-year-old male patient sustained a posterior transphyseal hip fracture-dislocation while playing football. A surgical hip dislocation with a trochanteric flip osteotomy, as described by Ganz and colleagues, was performed. Drilling of the dislocated epiphysis demonstrated no blood flow. Transepiphyseal and transphyseal fracture fixation with screws was performed. Two years after the injury, the patient had no evidence of osteonecrosis or functional limitations.

CONCLUSION: Traumatic transepiphyseal fracture-dislocations are rare injuries that commonly result in osteonecrosis. Application of the Ganz surgical hip-dislocation technique to a difficult pediatric hip fracture-dislocation achieved an excellent result.
