Abstract

Objective To describe the procedure and evaluate the results of a series of patients with stable and unstable pseudarthrosis of the scaphoids treated with the use of arthroscopy associated with cancellous bone graft and compression screw.

Methods Twenty-three patients were treated with this technique. The minimum postoperative follow-up was 12 months, and pre- and postoperative functional, clinical, and imaging analyses were performed.

Results Themean time from fracture to surgery was 26 months (12–60). Preoperative and postoperative clinical and radiological parameters were analyzed. The mean follow-up was 24.2 (12–60) months. Consolidation occurred in 22 patients (95.6%) in an average of 7.5 (4–12) weeks. Mean flexion range ofmotion improved from73.6° (60–80°) to 79.5° (60–90°); the range from 68.6° (50–80°) to 71.9° (45–85°); ulnar deviation from 20.6° (15–30°) to 26.9° (20–35°); and the radial deviation from 17.3° (15–25°) to 20.4° (10–25°). Pain (Visual Analog Scale [VAS] 0–10) improved from 7.3 (4–9) to 0.7 (0–6) and DASH functional scale improved from 49 (32–75) to 6 (2–12). The scapholunate angle improved from 69.1° (55–85°) to 48.4° (40–55°) and the radiolunar angle improved from 30° (10–40°) to 2.6° (0–8°).

Conclusion Treatment of stable and unstable pseudarthrosis of the scaphoid with spongy bone graft and percutaneous internal fixation, preferably with a headless compression screw, assisted by arthroscopy, showed good clinical and radiographic results in our series, with a short time for consolidation and functional recovery.

Work carried out at the Santa Casa de Misericórdia de Porto Alegre, Porto Alegre, RS, Brazil.
