Introduction

|---|
A traumatic dislocation of the hip associated with a femoral
head fracture was first described by Birkett1 in 1869. Almost a
century later, a classification of these injuries was proposed by Pipkin11,
whose name has since been associated with this lesion. The treatment
guidelines have evolved on the basis of a relatively limited series of
studies2,3,5,8,9,13,15. Emergency reduction of the hip is imperative,
regardless of the type or extent of the fracture13,16. Once reduction
is accomplished, further evaluation, including computed tomography,
is indicated to assess the congruity and stability of the joint.
Treatment options include nonoperative treatment, excision of fracture fragments,
open reduction and internal fixation, arthroplasty, and arthrodesis.
Complications associated with these injuries are avascular necrosis
of the femoral head, nonunion of the femoral head fragment, and
posttraumatic arthritis2,3,5-9,11-16.
We report on a patient with a Pipkin type-I fracture (fracture
of the femoral head distal to the fovea) treated . . . [Full Text of this Article]
