Risk Factors for Heterotopic Ossification in Traumatic Brain Injury: An Analysis of the Korean National Health...

Area of Science:

• Neuroscience
• Orthopedics
• Public Health

Background:

• Traumatic brain injury (TBI) can lead to heterotopic ossification (HO), a condition causing abnormal bone formation.
• Understanding HO risk factors in TBI patients is crucial for developing preventative strategies and improving patient outcomes.

Purpose of the Study:

• To investigate demographic, medical history, medication, and injury-related risk factors for HO in patients with TBI.
• To identify specific patient characteristics and clinical factors associated with increased HO incidence post-TBI.

Main Methods:

• Retrospective analysis of the Korean National Health Insurance Service (KNHIS) database.
• Inclusion of adult patients diagnosed with TBI (ICD-10 code S06) between 2004 and 2018.
• Analysis of factors including demographics, comorbidities, medications, and accompanying injuries.

Main Results:

• HO developed in 0.30% (1909/637315) of TBI patients.
• Risk factors included female sex, middle age (50s), preobesity/obesity, rheumatic diseases, comorbidities, and tracheostomy.
• Protective factors included smoking, anticonvulsants, antithrombotics, steroids, and NSAIDs.

Conclusions:

• Middle age, female sex, obesity, comorbidities, and disability increase HO risk in TBI patients.
• Certain medications (antiseptics) are associated with increased risk, while others (anticonvulsants, steroids, NSAIDs) are associated with decreased risk.
• Injury severity and systemic inflammation are implicated in HO development post-TBI.
