title: An unreported cause of early postoperative dislocation following total hip revision: massive intra-capsular oedema related to inferior vena cava filter thrombosis.
abstract: Inferior vena cava (IVC) filters are widely used to prevent pulmonary embolism (PE) in patients with an absolute or relative contraindication for anticoagulants, during the peri-operative period of trauma or total joint replacement. No complication specific to the orthopaedic's aspect of this practice has been described. We report the case of a patient who had major femoral head/cup separation mimicking dislocation following revision total hip arthroplasty related to massive intra-capsular oedema produced by IVC filter thrombosis. The patient could be successfully treated non-operatively. Orthopaedic surgeons should identify and refer patients with a complicated IVC filter, to identify any migration or occlusion, and also be aware that removable filters must not be kept in situ, once the high-risk phase of developing PE is past.
