Kagadal Further work requires larger sample sizes with a model capable of reproducing in vivo conditions and multidirectional forces, with radiographic bone density controls. This limitation of the methodology is somewhat imposed by variations in product design.
Error bars represent upper limits of standard error to demonstrate maximum displacement. Pathologic study of degeneration and rupture of the supraspinatus tendon.
Am J Sports Med ; A description of the cyclical loading protocol used to measure maximum tensile strength and displacement of anchors can be found alongside the online version of this article at www. In a bovine humeral model, Galland et al 6 icomix that although traditional anchors had higher mean tensile strength and lower elongation values at failure, there was no statistical difference between those and all-suture anchors.
Generally speaking, the findings reported in this study are consistent with those reported in the literature. Designed the study, Performed experiments, Subsequent data analysis, Co-drafted the paper. However, these sizes were not tested. The outcome and repair integrity of completely arthroscopically repaired large and massive rotator cuff tears.
However, when comparing displacement between 50 cycles and failure, there was no statistically significant variation between anchors. The humeral heads were dissected from cadaveric donors and overlying soft-tissue was debrided to expose the bone surface over the greater tuberosity.
Potential benefits include decreased bone damage. The JuggerKnot anchor had the greatest displacement at 50, and cycles and also at failure, though this did not reach statistical significance icobix any other all-suture anchors Table II apart from the Q-FIX anchor at failure Fig.
Circumferential laser-marks indicate the range of the depth to which the inserter can be pressed. Published online Mar 1. Mechanical properties and failure mechanisms observed of tested anchors 13 The mean maximum tensile strength value was significantly higher for the traditional anchor Displacement between 50 and cycles, 50 and cycles, and 50 cycles to failure were determined Table III.
All four types of commercially available all-suture anchors and one traditional plastic anchor were obtained from the manufacturers. It should be noted that other sizes of ICONIX anchor are available and indicated for RC repair surgery, however, literature published by the manufacturer states that the ICONIX 3 is the strongest defined by maximum tensile strength anchor within oconix range. With regard to gap formation of the construct, we found that the plastic control anchor had a mean total displacement of The aim of this study was to compare the mechanical properties failure load and cyclic displacement and failure mechanisms of all-suture anchors with those of a traditional suture anchor in cadaveric human humeral heads.
Furthermore, in a complete human cadaveric RC repair model, a standard single-row metal anchor repair demonstrated up to 7. Viscoelastic properties of stryer suture material used for rotator cuff repair and arthroscopic procedures.
Anchors and Interference Screws. Arch Surg ; Experimental constructs failed by a variety of mechanisms, with the majority of all-suture anchors failing by anchor pull-out, whereby anchor integrity was maintained.
An initial 10 N tension was placed on the anchors to ensure proper deployment of the subcortical segment of the all-suture anchors and to prevent loading artefacts. Supplementary material A description of the cyclical loading protocol used to measure maximum tensile strength and displacement of anchors can be found alongside the online version of this article at www. Variation in number of UHMWPE sutures could affect the tensile strength stryjer suture anchors, and not all anchors contained the same number of sutures.
ICONIX IntelliBraid Suture Anchors by Stryker This study compared the mechanical properties stryjer currently marketed commercial all-suture anchors, using a biologically representative ex vivo model, with a traditional bone anchor comparator. JuggerKnot and Y-Knot anchors Displacement, after initial application of load, was recorded during cyclic loading.
Support Center Support Center. This is in contrast to the traditional anchors, which failed by a combination of suture failure, anchor pull-out or eyelet breaking, consistent with what has been previously reported. The suture threads emerging from the humeral head were secured within the upper clamps of the rig, with no recorded failure in any repeats at the suture-vice interface Fig.
With the exception of the Q-FIX 4. Mechanism of failure suture or interface was also recorded. Anchors tested A review of the literature and a search through the procurement department of our tertiary referral centre hospital was conducted to determine current commercially available all-suture anchors accurate as of Aprilof which four were found.
Biomechanical comparison of a single-row versus double-row suture anchor technique for rotator cuff repair. Cyclic loading of transosseous rotator cuff repairs: However, there is limited published evidence for the relative strength of fixation for all-suture anchors compared with traditional anchors.

Presenta claramente las actividades de cada fase y exhibe una secuencia de pasos que deben ser seguidos. El objetivo es que a partir de los casos de uso se obtenga el sistema final. El ciclo de vida incremental consiste en desarrollar por partes el producto de manera que puedas integrarlas funcionalmente. Fundamentos de los procesos Tiene que ser lo suficientemente flexible como para adaptarse a diferentes estilos y tipos de problemas. Se deben analizar todos los requisitos formaran parte del sistema y con estos construir el diagrama de clases, que representa las agrupaciones funcionales que estructuraran el sistema en desarrollo. Para esta fase se utilizan 3 herramientas: Modelo de Dominio: esto se refiere a identificar objetos y cosas del mundo real que intervienen con nuestro sistema.
