腱板大 • 広範囲断裂に対する Debeyre-Patte 変法の腱板前進長評価

抄録

Background: It is important to demonstrate how we can advance the tip of torn rotator cuff in the decision of the operative procedure. The purpose of this study is to investigate the advanced length of the tip of torn rotator cuff after modified Debeyre-Patte procedure by magnetic resonance imaging (MRI).
Methods: We investigated 10 shoulders (6 rights, 4 lefts) of 10 patients after modified Debeyre-Patte procedure between 2008 and 2010. The mean contraction period, the mean age at operation, and the mean follow-up period were 5.6 months, 65.5 years old, and 20.6 months, respectively. We measured the advanced length of the tip of torn rotator cuff on the MRI in the preoperative and postoperative periods. The subacromial bursa portion of the largest rotator cuff tear on oblique coronal plane at superior facet and middle facet were identified. We discussed the relationship between fatty degeneration and the advanced length of the tip of torn rotator cuff. The preoperative fatty degeneration was judged by Goutallier's classification.
Results: The mean advanced length of the tip of torn rotator cuff was 40.0mm on average (21.7mm to 58.3mm) at superior facet and 44.6mm on average (26.5mm to 58.5mm) at middle facet. The advanced length wasn't related to be the amount of fatty degeneration.
Conclusion: These clinical results are good, and the advanced length of the tip of torn rotator cuff is considered to be one of the useful indicators of the decision of the operative procedure.
