Inferior Dislocation of the Hip: A Case Report and Literature Review

Abstract

We report on a 17-year-old man who underwent open reduction and internal fixation for an inferior dislocation of the right hip and displaced fractures of the right femoral head and neck, and antegrade intramedullary nailing for a displaced fracture of the left femoral shaft. In addition, 13 men and 4 women aged 5 to 56 (mean, 23) years with 16 unilateral and one bilateral inferior dislocation of the hip were reviewed from the literature.

Total hip arthroplasty in neglected, obturator type, hip dislocation in a young adult – an unusual case and literature review

“…4,5 In an obturator type of anterior hip dislocation, the mechanism of injury involves a force applied to an abducted hip, which is then flexed and externally rotated to dislocate the femoral head to lie anterior and inferior to the obturator foramen. 6 In our case, the patient who was sitting on a tree branch accidentally slipped and fell with his hips still in flexed, abducted and externally rotated position; during his descent, his thigh was struck by another branch which probably lead to the obturator type of hip dislocation.…”

Inferior hip dislocation after falling from height: A case report

“…Hip dislocation often occurs with high-energy trauma, since the hip joint is stabilised by surrounding thick, strong muscles and ligaments [1] , [2] , [6] . There are two distinct mechanisms of injury in an inferior dislocation [7] . Dislocation could be resulted from a high-fall, leading to an axial load to the femur in a flexed position or from an injury that forces the hip into wide abduction [7] .…”

“…Traumatic inferior hip dislocation is the least frequently seen of all hip dislocations and is generally an injury of the adults. In literature, it has been reported to occur generally following high-energy trauma and commonly seen with a concomitant femoral head or neck fracture [3] , [4] .…”

Unusual Posterior Traumatic Hip Dislocations at Yopougon/Abidjan Teaching Hospital

“…Very few cases have been reported. Most of the earlier reported cases involved the pediatric age group [3] [6] [19]. When the hip dislocates inferiorly, it is flexed to an extent that the distal end of the femur rises above the horizontal plane of the pelvis at the acetabular fossae level.…”

“…When the hip dislocates inferiorly, it is flexed to an extent that the distal end of the femur rises above the horizontal plane of the pelvis at the acetabular fossae level. The exact sequence of events resulting in the deformity is not always remembered [3] [6] [19].…”
