Summary
Psoas abscesses are a frequent complication of prosthetic hip infections, particularly hematogenous ones. Early diagnosis with CT scans is recommended for patients with prosthetic hip infection and a history of neoplasm.
Area of Science:
- Orthopedic Surgery
- Infectious Diseases
- Radiology
Background:
- Prosthetic hip infections can lead to serious complications.
- The association between prosthetic hip infection and psoas abscess is not well-established.
Purpose of the Study:
- To determine the frequency of prosthetic hip infections associated with psoas abscesses.
- To identify factors associated with the development of psoas abscesses in prosthetic hip infection patients.
Main Methods:
- A 2-year observational study was conducted.
- A case-control study design was used to analyze data from patients with prosthetic hip infection and psoas abscess.
Main Results:
- 12% of prosthetic hip infection patients had a concurrent psoas abscess.
- Psoas abscesses were significantly more common in hematogenous prosthetic infections (OR=93) and in patients with a history of neoplasm (OR=20).
Conclusions:
- Psoas abscess is a common, yet often under-diagnosed, complication of prosthetic hip infection.
- Abdominal CT scans are recommended for patients with hematogenous prosthetic hip infection or a history of neoplasm to detect psoas abscesses.
