Partial radiocarpal arthrodesis effectively treated wrist disorders, achieving bone union and pain relief in all patients. Radiocarpal fusion offers a viable solution for various wrist pathologies.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Wrist Arthroscopy

Background:

  • Partial radiocarpal arthrodesis is a surgical procedure to fuse specific joints in the wrist.
  • Indications include post-traumatic changes, Kienböck's disease, Madelung's deformity, and rheumatoid arthritis.

Observation:

  • Eight patients (5 male, 3 female; average age 44) underwent partial radiocarpal arthrodesis.
  • Procedures included radiolunate (5 cases) and radioscapholunate (3 cases) arthrodesis.
  • Follow-up focused on bone union, pain resolution, range of motion, and grip strength.

Findings:

  • All patients achieved bone union within 3 months.
  • Significant postoperative pain reduction was observed in 6 cases, with decrease in 2.
  • Radiolunate arthrodesis yielded a greater average flexion-extension arc (85°) and grip strength (68%) compared to radioscapholunate arthrodesis (35° and 51%, respectively).

Implications:

  • Partial radiocarpal arthrodesis demonstrates efficacy in managing diverse wrist disorders.
  • The choice of joint for arthrodesis impacts functional outcomes, with radiolunate fusion showing superior motion and strength.
  • Further research may explore long-term outcomes and optimal joint selection for specific wrist conditions.
