Pullout forces of sutures in muscle lacerations.

摘要

The purpose of this study was to determine if complex suture techniques had higher pullout forces from muscle tissue than conventional stitching. Using transected cadaver muscle bellies, we performed repairs with various suture techniques and measured pullout forces. Epimyseal repair with conventional stitches (Kessler, figure eight, horizontal mattress) was inferior to complex stitches (modified Mason-Allen, perimeter). The combined complex stitches (perimeter and Mason-Allen) were strongest. Conventional stitches failed longitudinally through the muscle, whereas complex stitches failed transversely across the muscle. The complex combination of perimeter and Mason-Allen stitches had superior pullout resistance compared to conventional stitches.
