Summary

Ulnohumeral arthroplasty for elbow arthritis offers modest range of motion improvements. While relatively safe, complete pain relief was achieved in only two-thirds of patients.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Degenerative arthritis of the elbow significantly impacts patient quality of life.
  • Ulnohumeral arthroplasty is a surgical option for managing severe elbow arthritis.

Purpose of the Study:

  • To evaluate the safety and efficacy of ulnohumeral arthroplasty.
  • To assess changes in pain and range of motion following the procedure.

Main Methods:

  • Nine ulnohumeral arthroplasties were performed on seven patients with degenerative elbow arthritis.
  • Patient outcomes were assessed at a mean follow-up of 26 months, focusing on pain levels and joint mobility.

Main Results:

  • Five out of nine elbows were pain-free post-surgery; two reported mild pain, and one reported moderate pain.
  • Significant improvements were observed in both elbow extension (p=0.02) and flexion (p=0.02).
  • One patient experienced a late supracondylar humerus fracture, successfully treated with open reduction and internal fixation.

Conclusions:

  • Ulnohumeral arthroplasty is a relatively safe and straightforward procedure for degenerative elbow arthritis.
  • The surgery provides modest gains in range of motion but does not guarantee complete pain relief for all patients.
