Damage control hip disarticulation: two-stage operation with index creation of a large medial flap for the septic hip.

Background: Although rarely performed, hip disarticulation (HD) is usually used for the patient with a non-viable leg who is also in extremis. HD was first used for trauma and infection; however, the technique was perfected during the age of hindquarter amputation for osteosarcomas. The operation performed by most surgeons today is still based on the oncological principles of high vessel control and ligation. When this approach has been used in the overwhelmingly infected or mangled extremity, it has resulted in high mortality rates. During the last 20 years, the concept of damage control operation has been embraced by emergency surgeons in all fields. We sought to extrapolate this concept and to apply it to the non-viable lower extremity.

Methods: We describe a new concept of damage control HD, review the technique and discuss our consecutive series of nine patients who underwent the procedure for trauma or necrotizing infection without flap dehiscence or mortality.

Results: All patients survived to hospital discharge. At time of discharge or at follow-up, six of the nine patients were able to transfer to a wheelchair.

Discussion: Proper disarticulations for infection need to address these two operative and postoperative issues: damage control debridement with creation of sufficient flap size and thorough postoperative wound care.Level IV.
