Insights
Heterotopic ossification (HO) is a complication in intensive care unit (ICU) patients. Three-phase bone scans (3pBS) can detect HO, with longer ICU stays correlating to more affected joints.
Area of Science:
- Medical Imaging
- Nuclear Medicine
- Intensive Care Medicine
Background:
- Heterotopic ossification (HO) is a recognized complication in intensive care unit (ICU) patients.
- Early detection and management of HO are crucial for patient outcomes.
Purpose of the Study:
- To examine the association of heterotopic ossification (HO) diagnosed by three-phase bone scan (3pBS) with various clinical parameters in ICU patients.
- To evaluate the utility of 3pBS in identifying HO in the ICU population.
Main Methods:
- Retrospective review of patient records from 2004-2016.
- Identification of patients diagnosed with HO via 3pBS and cross-referencing with ICU admission records.
- Analysis of demographic data, HO laterality, affected joints, and duration of ICU stay.
Main Results:
- 17 ICU patients were diagnosed with HO via 3pBS.
- HO was more common in males (92%) with a mean age of 38.
- HO predominantly affected lower limbs (hip) and upper limbs (elbow), with longer ICU stays correlating to more affected joints.
Conclusions:
- Heterotopic ossification (HO) is a significant complication in ICU patients.
- Three-phase bone scan (3pBS) is effective for early HO detection in this population.
- Screening ICU patients with 3pBS is recommended for timely management.
Background:
Heterotopic ossification (HO) is a potential complication in patients hospitalized in an intensive care unit (ICU). In this study we examined the association of HO diagnosed with three-phase bone scan (3pBS) in association with various parameters in patients previously hospitalized in ICU.
Material And Methods:
We retrieved patient records of the last 12 years subjected to 3pBS and diagnosed with HO from the Department of Nuclear Medicine (2004 up to 2016) and searched for a name match from ICU records.
Results:
We found 61 patients that had a positive 3pBS for HO of whom 17 patients were hospitalized in the ICU. Among the 17 patients, twelve fulfilled the study criteria and were included in the study. The mean age was 38 years and 92% were males. HO was unilateral in 7 and bilateral in 5 patients. Patients with unilateral HO had up to 2 joints with HO, while those with bilateral had up to 4 joints. HO was most frequently observed in lower limbs, with hip being the most common joint affected. In the upper limbs, HO occurred predominantly in bilateral joints with elbow being the most frequently involved joint. Patients with longer duration of ICU stay had more joints affected.
Conclusion:
HO is a potential complication in patients with ICU hospitalization. Since 3pBS is an imaging method for early detection of HO, patients hospitalized in ICU should be screened with 3pBS for appropriate management.
