About this product

Delta Xtend™ Reverse Shoulder System focuses on external joints like shoulders as care device of Replacement / Reconstruction. This device is a sum of semi-constrained shoulder arthroplasty. It gallops the usual connection amid the scapular and humeral mechanism, rotating the scapulo-humeral joint center of rotary motion medially and inferiorly. By doing this, it augments the deltoid lever arm in addition to the deltoid stress consequently allowing the strength of the deltoid group to recompense for the rotator cuff shortage. The Delta XTEND™ humeral stalk is premeditated for the paved obsession. The glenoid part is bolstering less with four coil as key fixation and HA wrapping for minor obsession.

O sistema reverso do ombro de Xtend™ do delta focaliza em junções externas como ombros como o dispositivo do cuidado da recolocação/reconstrução. Este dispositivo é uma soma da artroplastia semi-confinada do ombro. Galopa a conexão usual entre o mecanismo scapular e humeral, girando o centro comum scapulo-humeral do movimento giratório medially e inferiorly. Fazendo isto, aumenta o braço de alavanca do deltoid além do que o esforço do deltoid que permite conseqüentemente que a força do grupo do deltoid recompense para a falta do punho de rotator. A haste humeral do delta XTEND™ é premeditado para a obsessão pavimentada. A parte glenoid está amparando menos com a bobina quatro como a fixação chave e o HA que envolvem para a obsessão menor.

Division: Shoulder Reconstruction

The DELTA XTEND System is a total semi-constrained shoulder arthroplasty. It reverses the normal relationship between the scapular and humeral components, moving the scapulo-humeral joint center of rotation medially and inferiorly. By doing this, it increases the deltoid lever arm as well as the deltoid tension therefore allowing the muscles of the deltoid group to compensate for rotator cuff deficiency. Each design feature of the Delta XTEND Reverse Shoulder System was chosen to accelerate recovery, optimize function and maximize survivorship.

The DELTA XTEND Shoulder Monobloc Humeral Stem is designed for cemented fixation, while the Modular Humeral Stem is designed for cementless fixation. The glenoid component is cementless with four screws as primary fixation and HA coating for secondary fixation.

Features & Benefits

	Features	Benefits
	Cementless Modular Humeral Implant	Fluted stem design based on the GLOBAL® Shoulder Stem Design - positioned in anatomic version for optimal press-fit fixation¹ Hydroxyapatite (HA) coated titanium alloy for cementless application ^2,3 Centered and eccentric options to suit anatomy and optimize press-fit fixation 155° neck shaft angle for optimal joint stability⁴ Reduced proximal geometry for bone preservation
	Cemented Monobloc Humeral Implant	Polished Cobalt Chromium alloy for optimised cemented fixation⁵ Reduced proximal geometry for bone preservation Standard and long monobloc stems with suture hole fins and proximal height laser markings on the trial stem for use in proximal bone loss cases
	Polyethylene Humeral Cups	Three cup thicknesses (+3, +6 and +9mm) to balance soft tissue for optimal deltoid function based on clinical heritage⁶
	Glenoid Component	Centre of rotation on glenoid bone surface for high resistance to loosening shear forces⁴ Two locking cannulated variable angle screws (compress and lock) and two compression screws with +/- 10 degrees adjustable angulation for metaglene primary fixation, to maximize resistance to loosening shear forces⁴ Curved back and smaller metaglene, for bone preservation and low positioning on the glenoid to reduce risk of scapular bone erosion⁷ Standard (13.5mm) and Long Peg (+10mm and +15mm) Metaglenes allow for primary, revision and bone grafting
	DELTA XTEND CTA Heads	Hemi-heads available in two diameters and two head heights for easy revision from reverse to hemi-arthroplasty if required Extended articular surface for articulation against acromion
