Context: Kienbock disease is an idiopathic aseptic necrosis of the lunate, seen in adults of the younger age group. Although there are various surgical options, it is still controversial. Aims: The aim of this study was to evaluate functional outcomes after modified radial shortening osteotomy (RSO) for Kienbock. Settings and Design: Prospective interventional study using a consecutive sampling technique. Subjects and Methods: This prospective study was conducted at a tertiary care hospital. Our study was conducted between May 2022 and May 2023. Ten patients were treated by RSO, a lunate preserving extra-articular procedure, and followed up for 1 year. Range of movements (ROM), grip strength, and pain were evaluated in 10 patients. The outcome was measured by the Mayo wrist score. Statistical Analysis Used: Statistical data were analyzed by IBM SPSS 20.0 version software. Collected data were spread on Excel sheet and prepared a master chart. Through the master chart, tables, graphs, and diagrams were prepared. Results: Four males and six females with an average age group of 35.2 years with seven dominants and three nondominant were present in the study. After 1 year of follow-up, significant improvements in pain, grip strength, and ROM of the wrist were observed. Mayo wrist score was excellent in three, good in five, and fair in two. The mean Mayo score was 84.6. Conclusions: RSO, which is an extra-articular procedure, has good long-term clinical benefits and clinical improvement
