Long-term results following proximal row carpectomy.

Abstract

The functional outcome, patient satisfaction, and x-ray film status for 23 wrists were examined an average of 6 years following proximal row carpectomy. Surgery was performed for Kienbock's disease, scapholunate dissociation with periscaphoid arthritis, and scaphoid nonunion not suitable for bone grafting. Twenty patients were satisfied with functional performance and pain relief. Wrist flexion-extension arc averaged 74 degrees, or 61%, of the opposite wrist at a later examination. Grip strength, corrected dor dominance, averaged 79% of the opposite side, reflecting an average improvement of 15 kg force. Radiocarpal arthritis developed in three wrists, but only one required arthrodesis for pain relief. The majority of patients experienced satisfactory pain relief, functional wrist motion, and effective grip strength following proximal row carpectomy. The results did not decline at an average of 6 years after surgery.
