Summary
Coonrad prosthesis elbow replacement is a viable option for post-traumatic arthritis in carefully selected patients over 60. This study followed 53 patients, finding it reliable despite complex cases, with 38 elbows showing no progressive radiolucent lines.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
Background:
- Post-traumatic arthritis of the elbow presents significant management challenges, often requiring multiple prior surgeries and resulting in limited function or complications.
- Patients frequently have complex histories, including previous surgeries, joint stiffness, instability, or prior complications, making treatment decisions difficult.
Purpose of the Study:
- To evaluate the long-term outcomes of Coonrad prosthesis implantation for post-traumatic elbow arthritis.
- To assess the reliability and complication rates associated with this implant in a challenging patient cohort.
Main Methods:
- A retrospective follow-up of 55 consecutive elbow replacements using the Coonrad prosthesis for post-traumatic arthritis.
- Minimum two-year follow-up (mean 6.3 years) on 53 patients, analyzing revision rates, radiolucency, and functional outcomes.
- Detailed review of patient histories, including previous operations, complications, and pre-operative range of motion.
Main Results:
- Of 53 patients followed, 38 elbows showed no progressive radiolucent lines at follow-up.
- 10 patients (14 revisions) required further surgery, primarily for aseptic loosening.
- Two elbows were resected due to deep infection or bone resorption secondary to a foreign-body reaction.
Conclusions:
- The Coonrad prosthesis is a reliable option for treating post-traumatic elbow arthritis.
- Careful patient selection, particularly for individuals over 60 years old, is crucial for optimal outcomes.
- While effective, the prosthesis is associated with risks such as aseptic loosening and infection, necessitating vigilant monitoring.
