Area of Science:

  • Orthopedic Surgery
  • Surgical Innovation
  • Wrist Biomechanics

Background:

  • Ulna-shortening osteotomy is a key procedure for ulnar-sided wrist pain.
  • Achieving precise osteotomy and stable fixation is crucial for successful outcomes.
  • Existing methods present challenges in accuracy and fixation.

Purpose of the Study:

  • To introduce a novel device for precise ulna-shortening osteotomy.
  • To evaluate the efficacy and reliability of this device in clinical application.
  • To assess the union rates and complication profile following the procedure.

Main Methods:

  • Development of a specialized device for ulna osteotomy and fixation.
  • Application of the device in 24 ulna-shortening procedures.

  • Fixation using a 3.5-mm AO dynamic compression plate.
  • Radiographic assessment of osteotomy site union.

    • Main Results:

    • Successful precise shortening of the ulna in all 24 cases.
    • Average radiographic union achieved at 8.1 weeks post-surgery.
    • Zero instances of nonunion or delayed union were recorded.
    • Average follow-up duration of 36 months.

    Conclusions:

    • The developed device facilitates accurate ulna shortening.
    • This technique leads to predictable and reliable bone union.
    • It offers a reliable solution for ulna-shortening osteotomy in managing wrist disorders.
