Summary
Plain film radiography reliably measures graft size for superior capsular reconstruction (SCR). This study proposes three standard graft patch sizes for massive rotator cuff tears, aiding surgical planning.
Area of Science:
- Orthopedic surgery
- Radiology
Background:
- Superior capsular reconstruction (SCR) addresses massive, irreparable rotator cuff tears.
- Accurate graft sizing is crucial for successful SCR outcomes.
Purpose of the Study:
- To assess the reliability of plain film radiography for determining SCR graft size.
- To develop a database for predicting graft dimensions.
Main Methods:
- Inter- and intra-rater reliability study using plain film radiography on healthy shoulders.
- Measurements taken between the superior glenoid and supraspinatus footprint with specific positioning.
- Database created from 30 subjects using the established protocol.
Main Results:
- Excellent inter-rater (ICC=0.94) and intra-rater (ICC=0.76) reliability for radiographic measurements.
- Three distinct medio-lateral patch sizes (33 mm, 38 mm, 47 mm) were identified.
Conclusions:
- Plain film radiography is a reliable tool for measuring the glenoid-to-footprint distance.
- Three standardized graft patch sizes are proposed for SCR procedures.
