Area of Science:

  • Orthopedic surgery
  • Wrist biomechanics
  • Hand surgery

Background:

  • The pisiform bone is crucial for wrist stability.
  • Pisiform excision may lead to wrist dysfunction.
  • Pisotriquetral joint dysfunction requires evaluation.

Purpose of the Study:

  • To evaluate the functional outcomes of pisiformectomy.
  • To assess the impact of pisiform excision on wrist function.

Main Methods:

  • Functional evaluation of 20 patients post-pisiformectomy.
  • Comparison of operated vs. unoperated wrists.
  • Assessment of grip strength, wrist movement, and power.

Main Results:

  • 15 out of 20 patients reported complete symptom relief.

Related Experiment Videos

  • No significant differences in grip strength or wrist movement were observed.
  • Mild discomfort persisted in five patients.

    • Conclusions:

    • Pisiformectomy is a safe and effective treatment for pisotriquetral joint dysfunction.
    • Restoration of function and pain relief are common outcomes.
    • Surgical excision of the pisiform can be recommended.
