Comparative study between open and arthroscopic techniques for scaphoid excision and four-corner arthrodesis.This study presents our technique of arthroscopic scaphoid excision and four-corner arthrodesis and compares the clinical and radiological outcomes with those achieved with the open method.  Twenty-seven patients (14 in arthroscopy group and 13 in open group) were included.  Bone union was achieved in 13 of 14 patients in the arthroscopy group and in all 13 patients in the open group.  In the open group, severe stiffness (flexion-extension arc was 10°) occurred in one patient after surgery.  The mean postoperative flexion-extension arc was 75° and 51° in the arthroscopy group and open group, respectively.  The pain, clinical scores, and radiological indices were improved in both arthroscopy and open groups.  Arthroscopic and open scaphoid excision and four-corner arthrodesis did not show significant differences in clinical outcomes and bone union rates.  The arthroscopic method provided a superior range of motion.Level of evidence: III.
