[Long term results with a new lunate bone prosthesis].
In the University of Essen Orthopaedic Clinic a lunate prosthesis was developed. Three different sizes are available. The strongest indication for this prosthesis is complete destruction of the lunate. Advanced arthritis and heavy manual work are contraindications. Since 1974, fourteen prostheses have been implanted. Nine patients have been followed for an average of 2.1 years. Range of motion and strength of the wrist were reduced on the average of 50 percent. A higher proportion is free of pain despite evidence of progressive arthritis. This prosthesis may be a reasonable treatment modality for a problem without good therapeutic alternatives.
