We report outcomes for scapholunate-intercarpal ligamentoplasty ("SLIC procedure"), performed in 22 patients (mean age at surgery, 39.7 years), for reducible static scapholunate (SL) instability without repairable stump. Patients were evaluated for pain and active wrist range of motion, grip strength, functional scores (QuickDASH and PRWE) and radiological appearance (SL gap, SL angle, radiolunate angle, capitolunate angle), preoperatively and at a mean 28.3 months' follow-up (range 12-65). A CT scan without injection was performed at follow-up to measure the posterior radioscaphoid angle (PRSA). The objective was to assess radiological-functional correlations after SLIC ligamentoplasty and to analyze postoperative PRSA correction. The hypothesis was that correcting the PRSA improves clinical and functional outcomes. Pain on a visual analog scale improved significantly, from 2.7 to 0.7 at rest and from 7 to 3.2 during hand use. Mean wrist flexion was 46.4° and extension 59.1°. Grip strength reached 82.8% of the contralateral value. Functional scores improved significantly. Mean SL angle decreased significantly from 81.1° to 73.5°, and static scapholunate gap from 4.7 mm to 3.6 mm. Scaphoid subluxation was fully corrected in 15 cases (68%). PRSA angle was significantly corrected, from a mean 112.7° to 104.2°. Patients in whom PRSA was corrected showed a tendency for better clinical and subjective outcomes. There was 1 case of scaphoid necrosis, 7 of recurrent static instability, including 3 early at 4 months, 3 of scaphocapitate osteoarthritis, and 5 of carpal collapse with SLAC wrist. There were no significant correlations between clinical and radiological results in the medium term after SL ligamentoplasty by the SLIC procedure. The results were quite good in the medium term and pointed to the importance of correcting rotatory subluxation of the scaphoid, revealed by the PRSA, more than correcting the scapholunate gap.
