Clinical Scorecard: Investigation of Sternal Osteomyelitis Following Median Thoracotomy: A Prospective Cohort Analysis
At a Glance
Category
Detail
Condition
Sternal osteomyelitis (SO) post median thoracotomy
Key Mechanisms
Infection of sternal bone due to hematogenic spread or secondary to median thoracotomy; inflammation varies by histological section and surgical factors
Target Population
Patients undergoing median thoracotomy for cardiac surgery
Care Setting
Cardiac surgery and postoperative wound care units
Key Highlights
Secondary sternal osteomyelitis complicates 0.2–4.4% of median thoracotomy cases and is part of deep sternal wound infections.
Complete en bloc sternectomy with negative pressure wound therapy and flap coverage is effective for infection eradication.
Body mass index and left internal mammary artery (LIMA) harvest influence the degree of sternal bone inflammation; other comorbidities showed no significant impact.
Guideline-Based Recommendations
Diagnosis
Use microbiological and histopathological examination of resected sternal bone to confirm osteomyelitis.
Perform multiple histological sections of the sternum to assess inflammation extent.
Management
Indicate radical en bloc sternectomy when secondary closure is not feasible due to relapsing infections or bone destruction.
Apply negative pressure wound therapy post-debridement before secondary wound closure with musculocutaneous flaps.
Monitoring & Follow-up
Histopathological evaluation of resected bone sections to monitor inflammation intensity and infection resolution.
Risks
Higher body mass index correlates with increased sternal bone inflammation in specific sections.
LIMA harvest during coronary bypass surgery may increase inflammation in certain sternal sections.
Patient & Prescribing Data
Patients with deep sternal wound infections post median thoracotomy
Radical sternectomy combined with negative pressure wound therapy and flap coverage is effective; comorbidities like diabetes and smoking showed no significant effect on inflammation.
Clinical Best Practices
Interdisciplinary decision-making between cardiac and plastic surgeons for indication of radical sternectomy.
Use of en bloc sternectomy to remove infected bone entirely rather than piecemeal resection.
Employ negative pressure wound therapy followed by pedicled musculocutaneous flap coverage for wound closure.
