Arthroscopic scaphocapitate fusion without bone graft; clinical and radiological outcomes.

PURPOSE: Scaphocapitate fusion (SCF) is an important surgical option for carpal pathologies, which are difficult to manage as Kienböck's disease. With the advantages of arthroscopy combined with percutaneous fixation techniques, arthroscopic scaphocapitate fusion can have the best outcome for the patient from a functional perspective. This study aims to evaluate the clinical, radiological, and functional results of arthroscopic SCF.

METHODS

The study included thirty patients with stage IIIB and IIIC Kienböck's disease. The articular surfaces were prepared using arthroscopic burr then fixed by Herbert screw. The mean follows up period was about 29 months.

RESULTS

SCF was achieved in approximately seven weeks. There was a statistically significant difference in pre- and post-operative grip strength and Mayo wrist score.

CONCLUSION

According to our study findings, arthroscopic SCF may be performed with significant improvements and satisfactory clinical and functional results in patients with stage IIIB and IIIC Kienböck's disease.
