Objectives: This study aims to evaluate the efficacy of an alternative method by comparing an old established method with a new less invasive method in the surgical treatment of Stage 3A Kienböck’s disease.
Patients and methods: Between January 2014 and July 2018, a total of 35 patients (28 males, 7 females; mean age: 22.8±3.3 years; range, 17 to 29 years) who underwent surgery due to Kienböck’s disease were retrospectively analyzed. The patients were divided into two groups according to the procedure applied as the capitate forage procedure (CFP) group (Group 1, n=16) and the radial shortening osteotomy (RSO) group (Group 2, n=19). Patients with a minimum follow-up period of 18 months were examined according to the MAYO wrist scores pre- and postoperatively.
Results: The postoperative MAYO scores were statistically significantly higher in both groups (CFP, p=0.001; RSO, p=0.000). However, the osteotomy group showed statistically significantly higher results than the forage group in terms of not only postoperative scores, but also pre- and postoperative score difference (p=0.004).
Conclusion: Our study results confirm that both CFP and RSO are effective in the treatment of Stage 3A Kienböck’s disease. However, RSO should be the first choice in Stage 3A patients with high success rates. Supported by long-term follow-up results, CFP may be considered a minimally invasive alternative only in selected patients who avoid major surgery or expect a rapid return to work.
