Summary
A new lunate prosthesis offers a pain-free option for severe wrist destruction. While reducing motion and strength, it provides a viable treatment for a condition with few alternatives.
Area of Science:
- Orthopaedic surgery
- Biomedical engineering
Context:
- Development of a novel lunate prosthesis at the University of Essen Orthopaedic Clinic.
- Availability in three distinct sizes to accommodate patient anatomy.
Purpose:
- To evaluate the efficacy and outcomes of a newly developed lunate prosthesis.
- To determine the suitability of the prosthesis for patients with complete lunate destruction.
Summary:
- Fourteen lunate prostheses have been implanted since 1974, with nine patients followed for an average of 2.1 years.
- Patients experienced an average 50% reduction in wrist range of motion and strength.
- A significant proportion of patients reported pain relief, even with evidence of progressive arthritis.
Impact:
- The lunate prosthesis represents a potential treatment option for severe lunate destruction where therapeutic alternatives are limited.
- Highlights the trade-off between pain relief and functional deficit (motion/strength) in wrist arthroplasty.
