【Abstract】This paper discussed the injury mecha-
nism and management of a patient who had concomitant
ipsilateral hip and knee dislocations and contralateral open
leg fracture.
A 32-year-old man presented with ipsilateral fracture-
dislocations of the left hip (Pipkin’s type IV) and knee
(Moore II) joints and contralateral open fracture of the leg
bones after a car accident. After emergency resuscitative
measures, the hip joint was reduced and Pipkin’s fracture
was fixed using Ganz approach with lag screws; knee joint
was reduced closely and tibial plateau fracture was stabi-
lized with lateral buttress plate and a transarticular span-
ning fixator. The open fracture on the other leg was de-
brided and fixed with an external fixator. There was no insta-
bility in both joints after fixation when he was examined
under anesthesia. The fractures united after 3 months and
the patient had no residual instability of hip and knee. There
was no clinical or radiological evidence of osteonecrosis in
the hip joint after 6 months. At one-year follow-up, he had
satisfactory functional outcome with almost normal range
of motion at both joints.
Ipsilateral hip and knee dislocations are rare injuries and
more caution is needed for early diagnosis. A timely appro-
priate intervention can provide good functional outcome to
the patient in this situation.
