Summary

Capitellocondylar elbow replacements provided significant pain relief and improved range of motion in patients with arthritis. Survivorship analysis showed high prosthesis retention rates, despite notable complication rates including ulnar neuropathy.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Rheumatology

Background:

  • Elbow arthroplasty is a surgical procedure to restore function and alleviate pain in patients with severe elbow joint damage.
  • Capitellocondylar prostheses represent a specific type of total elbow replacement designed to mimic natural elbow biomechanics.

Purpose of the Study:

  • To evaluate the long-term clinical outcomes and survivorship of capitellocondylar elbow replacements.
  • To assess the functional improvements, pain relief, and complication rates associated with this prosthesis type.

Main Methods:

  • Retrospective analysis of 51 capitellocondylar elbow replacements in 41 patients (1976-1986).
  • Assessment of range of motion (flexion, extension, pronation, supination) and pain levels.
  • Radiographic evaluation using the Souter zonal system and Kaplan-Meier survivorship analysis.

Main Results:

  • Significant improvements observed in average flexion (20°), extension (4°), pronation (22°), and supination (36°).
  • 85% of patients reported complete pain relief; 15% experienced mild pain.
  • Complications included infection (8%), dislocation (6%), and ulnar neuropathy (31%). Survivorship was 88% at 1.4 years and 83% at 5.5 years.

Conclusions:

  • Capitellocondylar elbow replacements can achieve substantial functional restoration and pain relief in patients with elbow arthritis.
  • While effective, the procedure is associated with a significant risk of complications, particularly ulnar neuropathy.
  • Long-term survivorship is encouraging, but careful patient selection and management of potential complications are crucial.
