Partial Arthrodesis for the Treatment of Radiocarpal Osteoarthritis

Poorly reduced intra-articular fractures of the distal radius often result in the development of radiocarpal degenerative osteoarthritis. This complication is frequent, particularly when the fragments have healed malrotated or depressed in relation to the surrounding joint surface. Increased stress concentration in areas with a marked step enhances cartilage wear and subsequent synovitis. When symptomatic, this problem may be addressed by using a variety of noninvasive strategies including physiotherapy, resting splints, anti-inflammatory medication, and activity modification. If these methods fail, a number of surgical procedures may be indicated. This article reviews the technique, indications, and results of the different radiocarpal fusions that eventually may be used to alleviate the symptoms caused by a badly damaged radiocarpal joint.
