LungTx-Lock: Comparative Study Between Sternal Closure With Sternalock® Blue Versus Steel Wire Submitted To Bilateral Anterior Transsternal Thoracotomy (Clamshell) For Bilateral Lung Transplant
Study Details
Study Description
Brief Summary
This will be a prospective, randomized clinical trial, comparing the sternal alignment between the fixation with rigid plate X steel wires. Patients over 18 years of age, belonging to the lung transplant line in the State of São Paulo, who will undergo bilateral lung transplantation will be studied.

Outcome Measures
Primary Outcome Measures
- Sternal Alignment [1 month]
Sternal alignment will be analyzed through cross-sections of chest computed tomography by a certified radiologist. Two parameters will be used for sternal alignment: Misalignment: Significant:> 3mm; Non-significant: ≤3mm Deviation: Grade 1: ≤50% Grade 2:> 50%
- Sternal Alignment [3 months]
Sternal alignment will be analyzed through cross-sections of chest computed tomography by a certified radiologist. Two parameters will be used for sternal alignment: Misalignment: Significant:> 3mm; Non-significant: ≤3mm Deviation: Grade 1: ≤50% Grade 2:> 50%
- Sternal Alignment [6 months]
Sternal alignment will be analyzed through cross-sections of chest computed tomography by a certified radiologist. Two parameters will be used for sternal alignment: Misalignment: Significant:> 3mm; Non-significant: ≤3mm Deviation: Grade 1: ≤50% Grade 2:> 50%
Secondary Outcome Measures
- Bone healing [1 month]
Bone healing will be analyzed through cross-sections of chest computed tomography by a certified radiologist. • The degree of bone healing will be classified into 6 levels: 0- (A) No signs of consolidation (no clear consolidation, no union, sternal separation) (B) Minimal consolidation (sternal separation, lack of bone bridge) (C) Median consolidation (sternal separation with some trace of bone bridge, immature bone formation) (D) Moderate consolidation (partial bone connection indicating sternal stability) (E) Partial synthesis (significant bone bridge) (F) Complete synthesis (complete bone bridge)

- Pain [1 month]
The patients' postoperative pain will be assessed according to the Pain Score (Pain Score).
- Pain [3 months]
The patients' postoperative pain will be assessed according to the Pain Score (Pain Score).
- Pain [6 months]
The patients' postoperative pain will be assessed according to the Pain Score (Pain Score).
- Time to close the Rib cage [1 month]
Time to close the Rib cage will be measured from the insertion of the last chest drain until the total closure of the skin of the thorax.
- Time to close the Rib cage [3 months]
Time to close the Rib cage will be measured from the insertion of the last chest drain until the total closure of the skin of the thorax.
- Time to close the Rib cage [6 months]
Time to close the Rib cage will be measured from the insertion of the last chest drain until the total closure of the skin of the thorax.
