Area of Science:

  • Orthopedics
  • Hand Surgery
  • Arthroscopy

Background:

  • Metacarpophalangeal (MP) joint arthroscopy is underutilized despite its potential.
  • Limited literature exists on MP joint arthroscopic anatomy and clinical applications.

Purpose of the Study:

  • To describe the arthroscopic anatomy of the MP joint.
  • To evaluate the clinical utility of MP joint arthroscopy for various conditions.

Main Methods:

  • Cadaveric dissection of 24 MP joints using small joint arthroscopy.
  • Identification of key arthroscopic anatomical landmarks.
  • Clinical case review of MP joint arthroscopy applications.

Main Results:

  • Detailed description of 7 arthroscopic anatomical landmarks, including collateral ligaments, synovial recesses, and meniscal equivalents.

    • Conclusions:

    • MP joint arthroscopy provides a clear view of intra-articular structures.
    • The technique is valuable for diagnosing and treating MP joint pathology.
    • Arthroscopic approach offers advantages similar to larger joint arthroscopy, with expanding indications.
