Simultaneous asymmetrical bilateral hip dislocations - A report of three cases with different presentations and management.

Background: Simultaneous traumatic dislocation of both the hips in an individual is an uncommon injury. It accounts for only 1-2% of all traumatic hip dislocations. Simultaneous traumatic dislocation of both the hips in opposite directions i.e., anterior dislocation of one hip and posterior of the other is even rarer. These asymmetric dislocations need prompt identification for appropriate management. While their management should proceed in a manner commensurate with the accepted management of isolated dislocations to avoid complications, it is the timely identification which is essential.

Study Details: Retrospectively the details of three patients with asymmetric bilateral hip dislocations were collected. The article describes the clinical presentation of each patient and the management offered to them. The follow up duration ranged from 15 months to 24 months.

Results: In the short term, the outcomes in terms of hip pain, movements at the hips and radiological parameters like absence of arthritic or avascular changes were found to be satisfactory in each patient.

Conclusion: Early diagnosis and prompt reduction is the essential first step in the appropriate management of these patients to prevent the possible complications. The associated fractures must be managed as per the established principles of trauma care. Long term follow up is essential for identifying if complications like avascular necrosis and secondary osteoarthritis develop after this uncommon injury.
