Long-term results after repair and augmentation ligamentoplasty of rotatory subluxation of the scaphoid.
Twenty-two patients had scapholunate ligament repairs combined with a new augmentation ligamentoplasty for chronic scapholunate dissociation. All were evaluated by physical and radiologic examination after a mean postoperative follow-up period of 63 months (range, 12-134 mo). According to Green and O'Brien and Johnson and Carrera scores 5/8 had excellent, 13/12 good, and 4/2 fair results. Thirteen were free of pain; 6 had mild pain and 3 had moderate pain. Nineteen returned to their original occupation. There was an average loss of 10 degrees of flexion, 9 degrees of extension, and 11% of grip force compared with the opposite wrist. Radiologic examination showed an average decrease of 12 degrees of the scapholunate and 10 degrees of the radiolunate angles compared with the levels before surgery. No signs of degenerative osteoarthritis were found in 16 (73%) cases. Five wrists showed a distinct pattern of midcarpal degeneration correlating with notable dorsal intercalated segment instability after surgery, and 2 cases had signs of radioscaphoid degeneration.
