Absorb the benefits of strong, versatile rotator cuff repair
TWINFIX◊ Ultra HA Suture anchors with ULTRABRAID◊ Suture combine strength, versatility and biocompatibility for optimal rotator cuff repairs.
Strength
- Transitional thread design provides secure fixation with distal “cutting” threads for easier insertion and proximal “locking” threads for stronger pullout strength, even in poor bone quality.1
- The anchor is designed to be supported by the internal driver to optimize force transfer during insertion into bone.
- ULTRABRAID Suture provides stronger knot strength than competitivesuture and a low-profile knot stack.2
Versatile
- Multiple anchor sizes: 4.5 mm, 5.5 mm 6.5 mm
- Multiple suture configurations; with double or triple ULTRABRAID Sutures.
- Specific hole preparation instruments address differing humeral bone quality.
Biocompatible
- Bio-composite material, PLLA-HA is a natural bone mineral shown to promote bone replacement.3
- HA (hydroxyapatite) exists in the body, making it naturally biocompatible.
- HA provides a consistent degradation cycle by neutralizing the acidity of the area, allowing higher strength retention over time.4
