A rare material reaction to suture anchors caused shoulder joint erosion and necrosis. Surgical removal of anchors led to rotator cuff healing, suggesting a foreign body bioreaction.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Pathology

Background:

  • Suture anchors are commonly used in orthopedic surgery for soft tissue fixation.
  • Material reactions to suture anchors, while possible, are infrequently reported in medical literature.
  • Diagnosing non-infectious complications of orthopedic implants can be challenging.

Observation:

  • A patient presented with symptoms suggestive of shoulder joint pathology.
  • Initial investigations, including infection markers, were negative.
  • A second surgery revealed bone erosion and necrotic tissue around the suture anchors, with anchors protruding from the bone.

Findings:

  • Pathological examination of necrotic tissue showed foreign body giant cells containing particulate material.

  • The rotator cuff healed after revision surgery without the use of anchors.
  • Infection was ruled out by multiple tests, indicating a non-infectious etiology.

    • Implications:

    • This case highlights the potential for rare material reactions to suture anchors, possibly metal- or suture-induced.
    • It underscores the importance of considering non-infectious inflammatory responses in cases of implant-related complications.
    • Further research into the biocompatibility of orthopedic implant materials is warranted to minimize such adverse events.
