Summary

This study recommends the extensor digiti minimi tendon transfer to prevent recurrent ulnar drift in rheumatoid arthritis patients. This surgical technique effectively corrects the deformity with minimal functional issues.

Area of Science:

  • Orthopedic Surgery
  • Rheumatology
  • Hand Surgery

Background:

  • Rheumatoid arthritis frequently causes ulnar drift, a common deformity.
  • Existing surgical treatments for ulnar drift often result in recurrence.

Purpose of the Study:

  • To evaluate the efficacy of extensor digiti minimi tendon transfer in preventing recurrent ulnar drift.
  • To assess the functional outcomes of this tendon transfer in patients with rheumatoid arthritis.

Main Methods:

  • The extensor digiti minimi tendon insertion was relocated to a dorsal-radial position.
  • This tendon transfer was performed on 28 patients over 6 years.
  • Outcomes were evaluated more than 1 year post-surgery.

Main Results:

Related Experiment Videos

  • Metacarpal phalangeal joint extension averaged 52 degrees post-surgery.
  • No recurrence of ulnar drift was observed in any patient.
  • Slight hyperextension (<5 degrees) occurred in about half of patients but was not functionally problematic.

Conclusions:

  • Extensor digiti minimi tendon transfer is an effective method to prevent recurrent ulnar drift in rheumatoid arthritis.
  • This technique is recommended for patients undergoing metacarpal phalangeal joint replacement for rheumatoid arthritis.
