Ulnar shortening osteotomy effectively treats ulnar impaction syndrome, improving wrist pain and function. This surgical technique offers rapid healing without the need for postoperative cast immobilization, leading to satisfactory patient outcomes.

Area of Science:

  • Orthopedic surgery
  • Hand and wrist surgery
  • Skeletal biomechanics

Background:

  • Ulnar impaction syndrome can cause significant wrist pain and dysfunction.
  • Surgical intervention is often necessary to alleviate symptoms and restore function.
  • Ulnar shortening osteotomy is a recognized surgical technique for managing this condition.

Purpose of the Study:

  • To evaluate the functional and radiographic outcomes of ulnar shortening osteotomy for ulnar impaction syndrome.
  • To assess the efficacy of a specific oblique osteotomy and compression plating technique.

Main Methods:

  • Retrospective analysis of 18 patients undergoing ulnar shortening osteotomy over 10 years.
  • Utilized an oblique osteotomy with AO compression plating.

  • Assessed outcomes using the modified wrist grading system of Chun and Palmer pre- and post-operatively.

    • Main Results:

    • All 18 osteotomies achieved bony union within 6-8 weeks.
    • Significant improvements noted in pain, function, grip strength, and range of motion at an average 3-year follow-up.
    • 16 out of 18 patients achieved excellent or good functional grades; no major complications, though 8 required plate removal for discomfort.

    Conclusions:

    • Ulnar shortening osteotomy with oblique osteotomy and AO compression plating is a straightforward and effective procedure for ulnar impaction syndrome.
    • The technique is associated with rapid bone healing and satisfactory functional and radiographic outcomes.
    • Postoperative cast immobilization is not necessary, potentially improving patient comfort and early mobilization.
