Summary

Total elbow replacement using capitellocondylar prostheses showed improved motion but limited functional gains. Complications like dislocation and nerve palsy occurred, though the lateral Kocher approach reduced ulnar-nerve issues.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Retrospective review of 40 total elbow replacements using capitellocondylar prostheses.
  • Average follow-up of 7.2 years in 35 patients.

Observation:

  • Significant improvements in pronation, supination, and flexion.
  • Limited improvement in elbow extension.
  • Ewald et al. rating improved from 30 to 88 points.
  • American Rheumatism Association functional score improved in only 4 patients.

Findings:

  • 29% malarticulation or dislocation rate.
  • 2 deep infections requiring prosthesis removal.
  • 10 prostheses showed radiolucent lines without pain or loosening.
  • 7 transient ulnar-nerve palsies observed.

Implications:

  • The capitellocondylar prosthesis offers functional improvements but has notable complication rates.
  • Adoption of the lateral Kocher approach decreased the incidence of ulnar-nerve palsy.
  • Further research needed to optimize outcomes and minimize complications in total elbow arthroplasty.
