Material reaction to suture anchor.

Arthroscopy

Orthopedic Center of Southern Illinois, Mount Vernon, Illinois, USA.

Published: March 2004

The authors present a case of material reaction to suture anchor, which is rarely reported. Leukocyte rate, leukocyte differential, multiple cultures, and gram stain test could not prove infection. A second surgery for exploration of the shoulder joint was performed to reconstruct the rotator cuff without using anchors, and the rotator cuff tear healed after the second surgery. During the second surgery, the bone surrounding the anchors was found to be eroded and substituted with necrotic tissue. The anchors protruded outside the bone. The pathological examination of the necrotic tissue showed multinucleated giant cells of foreign body type, some of which had engulfed minute splinters of particulate foreign material. Either metal- or suture-induced bioreaction is suspected in this case.

Background: Groove pancreatitis (GP) is a form of pancreatitis that affects the pancreaticoduodenal groove area, which lies between the head of the pancreas, the second part of the duodenum and the distal bile duct, presenting as abdominal pain and gastric outlet obstruction. In this study, we present the clinical and radiological characteristics of individuals diagnosed with groove pancreatitis at our center and discuss the use of a conservative treatment approach in managing GP.

Methods: The data of patients with groove pancreatitis treated at our center between January 2012 and December 2021 was analyzed.
