Abstract
The aim of this study was to compare the results of Matti-Russe (MR) procedure and interpositional techniques (IT) in the management of scaphoid non-union.
50 scaphoid non-unions were included in this retrospective study. Demographics, initial management of fracture, location of non-union, time to surgery, procedure done and immobilisation time were recorded. Radiographs were analysed for union and deformity correction. Functional outcome was analysed using the Herbert's grading system.
The mean age and time to surgery were 26.7 years and 15.9 months. Twenty-one patients had the MR procedure and twenty-nine patients had interpositional procedures with internal fixation. DISI was present in 17 patients. The mean postoperative change in the scapholunate angle with the MR procedure was 7.9° compared to 8.0° (p>0.05) for the IT procedures. Union rate was 76% for both procedures. The mean follow-up was 9.9 months. Functional results were Herbert 0 or 1 in 42 cases.
The only significant prognostic variables were location of non-union and time to surgery. Similar deformity correction was achieved using both IT and MP procedures. MP procedure can be used in the management of scaphoid non-union even in the presence of deformity with good functional results.
