Effects of Calcium Carbonate Particulate Releasing Surgical Anchors on Bone and Tendon Healing

چکیده
The Calaxo @ screw, developed by Smith and Nephew, is a novel biomedical composite composed of poly-DL-lactide-co-glycolide (PLLA:PGA) 85:15 and calcium carbonate particulates. Comparisons to an identical surgical anchor composed of PLLA, largely considered an industry standard, shows increased mean failure strength in surgical reconstructions of the patellar-tibia complex in sheep. SEM imaging confirms the osteoconductivity of the Calaxo @ screw proposed in previous studies and also suggest a positive effect on the differentiation of tissues along the tendon-bone interface. These findings support the intended use of the Calaxo @ screw as a fixation device for rotator cuff repair procedures.

Frontal Plane Humeral Elevation Effects on the Pullout Strength of Suture Anchors Used in Rotator Cuff Repair
Frontal plane humeral elevation effects on the pullout strength of suture anchors used in rotator cuff repair The rotator cuff offers the stabilizing forces necessary for fine arm movement. The most common injury to the rotator cuff is the partial or full thickness tear of the supraspinatus tendon, which attaches the humerus to the scapula on the superior side, due to an acute or chronic injury...
متن کاملTendon-bone Healing in a Rat Cannulation Model
INTRODUCTION: Prior research has examined complex methods of biologic augmentation during rotator cuff repair, including tendon transplants and extracellular matrix grafts. Our proposed procedure utilizes local autogenous bone marrow delivered to the repair site via a cannulated humeral implant. Such marrow delivery channels could be developed for suture anchors and other surgical hardware and ...
متن کاملRotator Cuff Healing and the Bone Marrow ‘‘Crimson Duvet’’ From Clinical Observations to Science
The goal of improving rotator cuff healing has been a high priority for orthopedic shoulder surgeons since Codman showed the feasibility of repair in 1909. Early efforts were directed toward improving surgical techniques to optimize the mechanical tendon fixation to bone. These efforts have been very successful and include improved sutures and bone anchors, less complicated suture passing and k...
متن کاملComparison of the Fixation Strength of PEEK Knotless Suture Anchors for Rotator Cuff Repair
INTRODUCTION Rotator cuff injuries are common, with approximately 400,000 cuff repairs performed each year in the United States alone. Surgical repair of torn cuff tendons involves reattachment of the torn end of the tendon to the original footprint on the proximal humerus, typically using suture anchors. In recent years, suture anchors have evolved into knotless systems, which are designed to ...
متن کاملAchilles Tendon Repair Using the InternalBrace Principle.
Despite extensive research, the management of acute ruptures of the Achilles tendon remains an area of controversy, and there is no consensus regarding the optimal treatment. An InternalBrace (Arthrex, Inc., Naples, Florida) is a ligament augmentation repair using high strength sutures/tape and knotless bone anchors which encourages healing and allows early mobilization. This article describes...
