Orthosorb: a case of foreign-body reaction
1St. Vincents Hospital, Vancouver, B.C., Canada.
Summary
A rare foreign-body reaction occurred after poly-p-dioxanone pin fixation for a metatarsal osteotomy. Diagnosis involved imaging, and the patient experienced partial recovery with persistent pain.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
- Pathology
Background:
- Distal first metatarsal head osteotomies are common orthopedic procedures.
- Poly-p-dioxanone (PDS) pins are utilized for fixation due to their bioabsorbable properties.
Observation:
- A previously unreported foreign-body reaction was identified.
- The reaction was associated with poly-p-dioxanone pin fixation.
Findings:
- Diagnosis was confirmed via fine-needle aspiration under fluoroscopic guidance and computed tomography (CT) scan.
- The patient showed a positive response to conservative management and time.
Implications:
- This case highlights a potential complication of PDS pin fixation in foot surgery.
- Awareness of this reaction is crucial for orthopedic surgeons.
- Further investigation into PDS material biocompatibility may be warranted.
