New percutaneous synovial biopsy (PSB) techniques improve large joint access. These refined fluoroscopy-guided methods significantly increased the success rate of obtaining synovial membrane tissue for diagnosis.

Area of Science:

  • Orthopedics
  • Medical Imaging
  • Surgical Techniques

Background:

  • Percutaneous synovial biopsy (PSB) is crucial for diagnosing joint conditions.
  • Existing techniques for large joints (excluding the knee) have limitations.
  • Fluoroscopy guidance is essential for minimally invasive procedures.

Purpose of the Study:

  • To develop and refine percutaneous synovial biopsy (PSB) techniques for large limb joints.
  • To improve the success rate and safety of synovial tissue sampling.
  • To establish optimal procedural modifications for enhanced diagnostic yield.

Main Methods:

  • Development of new fluoroscopy-guided percutaneous synovial biopsy (PSB) techniques.
  • Application of modified techniques using Tru-Cut and Jamshidi needles.

  • Focus on needle placement, cutting window orientation, and optimal approach selection.
  • Biopsies performed on an outpatient basis under local anesthesia.

    • Main Results:

    • Eighty-four biopsies were successfully performed across various large joints (hip, shoulder, elbow, wrist, ankle).
    • Refined techniques, including needle combination and precise placement, significantly improved the success rate.
    • The success rate for obtaining synovial membrane increased from 48% to 81%.
    • No procedural complications were reported.

    Conclusions:

    • New percutaneous synovial biopsy (PSB) techniques offer an effective method for sampling large joints.
    • The refined fluoroscopy-guided approach enhances diagnostic accuracy and patient safety.
    • These improved techniques represent a significant advancement in minimally invasive joint diagnostics.
