Risk factors associated with subtalar fusion within 5 years following calcaneal ORIF

Area of Science:

• Orthopedic Surgery
• Trauma Surgery
• Health Services Research

Background:

• Calcaneal fractures often require open reduction internal fixation (ORIF).
• Subtalar fusion (STF) may be necessary for persistent pain and arthritis post-ORIF.
• Identifying risk factors for STF after calcaneal ORIF is crucial for patient management.

Purpose of the Study:

• To evaluate patient demographics, comorbidities, and reimbursement data as risk factors for STF after calcaneal ORIF.
• To determine the association between specific comorbidities and the incidence of STF.
• To inform treatment strategies and optimize outcomes for patients with calcaneal fractures.

Main Methods:

• Retrospective analysis of a national claims database (2010-2021).
• Inclusion of patients who underwent calcaneal ORIF.
• Multivariate logistic regression to identify risk factors for STF within a 5-year follow-up period.

Main Results:

• Higher proportions of alcohol abuse, depression, drug abuse, obesity, and tobacco use were observed in patients who underwent STF.
• Depression (OR: 1.54) and obesity (OR: 1.58) were significantly associated with an increased odds of STF.
• No significant differences in reimbursement data or demographics were found between STF and non-STF groups.

Conclusions:

• Alcohol abuse, tobacco use, drug use, obesity, and depression are associated with an increased need for STF following calcaneal ORIF.
• These comorbidities represent key risk factors influencing the long-term outcomes of calcaneal fracture treatment.
• The findings highlight the importance of addressing these patient factors in surgical planning and post-operative care.
