Abstract:

Background: The purpose of the study was to evaluate the functional and radiographic outcomes of arthroscopic lunate decompression versus radial osteotomy in the treatment of Kienböck disease (KD).

Methods: In a prospective cohort design, we enrolled 82 patients with KD with Lichtman stages I to IIIb. Participants assigned themselves to groups by choosing either arthroscopic lunate core decompression and synovectomy (group A; n = 54) or radial osteotomy (group B; n = 28). For radial osteotomy, a distal radius volar approach was used and a shortening osteotomy (in negative and neutral ulnar variance) or lateral closing wedge osteotomy (in positive ulnar variance) was performed. Arthroscopic lunate core decompression was performed under direct visualization from the 3-4 portal using a shaver (through the 6R portal) and a cutting burr (through the trans-4 portal). The shortened Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score, visual analog scale (VAS) score for pain, wrist passive flexion/extension, grip strength, and radiographic assessments (Lichtman classification, radioscaphoid angle, carpal height ratio) were recorded before surgery and at the final follow-up.

Results: Sixty-four patients were included in the final analysis (44 in group A and 20 in group B). The mean ages of participants were 33 ± 11 years in group A and 31 ± 8 years in group B. The mean follow-up periods were 44 ± 20 months in group A and 37 ± 23 months in group B. The QuickDASH score, VAS score, and passive wrist movements significantly improved in both groups. Grip strength showed a significant increase in group A only. The postoperative functional analysis between the 2 groups showed no significant difference, except for the wrist passive extension, which was higher in group A. Lichtman staging remained the same in 79.5% and 73.6% of patients in groups A and B, respectively.

Conclusion: An arthroscopic lunate core decompression and wrist synovectomy has comparable midterm results to radial shortening osteotomy in the treatment of KD.
