Simultaneous Ipsilateral Floating Hip and Knee: A Complex Combination and Difficult Surgical Challenge

Abstract

Simultaneous ipsilateral floating hip and floating knee are extremely rare. To the best of our knowledge, only four cases have been described in the literature. This uncommon injury is mostly caused by high-velocity impact and associated with life-threatening lesions. We report a unique case of concomitant ipsilateral floating hip and floating knee following road traffic accident. The patient presented ipsilateral hip dislocation and acetabular, femoral, and tibial fractures associated with chest trauma. The aim of this report is to highlight the severity and rarity of this combination and to describe the therapeutic recommendations.

“Floating Hip” and “Floating Knee” Associated with Hip Dislocation, Sciatic Nerve Palsy, and Patella Fracture [RETRACTED]

“…Although similar cases of SIFHFK injuries have been described previously by Benabbouha et al 3 and Li et al, 4 E-mail address for M.K. Saini: sainimk.saini8@gmail.com…”

“…Although similar cases of SIFHFK injuries have been described previously by Benabbouha et al 3 and Li et al, 4 our case was peculiar because of the associated neck and the shaft of femur fracture, patella fracture with fracture acetabulum, and hip dislocation. SIFHFK injuries are typically the result of high-velocity trauma and should be approached in a multidisciplinary, stepwise manner for optimal surgical stabilization.…”

“…In this case, we chose SIF because the femur head fragment was free floating and we could achieve good static compression at neck fracture while planned for controlled dynamic compression at shaft fracture. In our case, the patient had excellent hip function with Harris hip score being 93 at 2 years follow-up, whereas other authors also reported fair to good clinical results in previous reports and reviews 3,4,11 .…”

“…SIFHFK injuries have been rarely reported in the literature, and only 2 cases of SIFHFK injuries with hip dislocation have been previously reported 3,4 . We hereby report on a unique case of SIFHFK with hip dislocation and patella fracture-associated sciatic nerve injury.…”

“…Open reduction of hip and tibial external fixation was done in the first stage for the grade 2 open fracture. In the second stage 2 days later, they did femoral nailing and posterior acetabular fixation [ 9 ].…”
