Abstract

INTRODUCTION:

Psoas abscess associated with hip arthroplasty infection is a rare entity. The aim of this report was to review our experience.

MATERIAL AND METHODS:

Patients with computerized tomography (CT) diagnosis of psoas abscess associated with a hip arthroplasty infection from 2004 to 2009 were retrospectively reviewed. Demographics, microbiological data, CT results and outcome of each patient were recorded.

RESULTS:

Seven patients out of 214 evaluated by CT due to hip infection suspected were identified. Three women and 4 men, with a mean age of 69 years (range 46-89). Mean abscess diameter was of 62 x 47 mm. In all cases, a direct communication between abscess and prosthesis was observed. The most commonly isolated microorganisms were grampositive cocci. All patients were treated with two-stage revision surgery. After a mean follow-up of 65 months (28-113), six patients were in remission.

CONCLUSIONS:

The use of CT in the study of suspected infection of a hip arthroplasty identified a psoas abscess in 7 cases out of 214 evaluated. Patients treated with two-stage revision surgery and large debridement was associated with a good clinical outcome.
