Caveat arthroplasty, surgery for presumed benign conditions, can mask underlying extraarticular tumors. Early detection and referral to orthopedic oncologists are crucial to avoid unnecessary procedures and ensure proper cancer treatment.

Area of Science:

  • Orthopedic Oncology
  • Surgical Pathology
  • Diagnostic Imaging

Background:

  • Caveat arthroplasty involves joint replacement for presumed non-neoplastic conditions.
  • These procedures may mask or delay the diagnosis of underlying extraarticular tumors.
  • Misdiagnosis can lead to delayed oncologic treatment and poorer patient outcomes.

Purpose of the Study:

  • To analyze cases of caveat arthroplasty performed before diagnosis of malignancy.
  • To identify factors contributing to misdiagnosis and delayed cancer detection.
  • To recommend strategies for avoiding caveat arthroplasty in suspected neoplastic cases.

Main Methods:

  • Retrospective review of 6 patients who underwent caveat arthroplasty.
  • Analysis of pre- and intraoperative findings, including radiographic evidence.

The Use of Mixed Reality in Custom-Made Revision Hip Arthroplasty: A First Case Report

Published on: August 4, 2022

  • Assessment of patient history, symptoms, and time to neoplasm discovery.

    • Main Results:

    • Three patients completed arthroplasty before neoplasm diagnosis (average 29 weeks post-op).
    • Three arthroplasties were aborted due to intraoperative discovery of malignancy.
    • Preoperative radiographs in 4 patients showed evidence suggestive of malignancy.

    Conclusions:

    • Caveat arthroplasty can be avoided by considering malignancy preoperatively, especially with atypical symptoms or history of cancer.
    • Intraoperative detection of neoplasm necessitates abortion of the planned arthroplasty.
    • Suspected malignancy cases require prompt referral to a musculoskeletal oncologist.
