Summary
Scaphotrapezio-trapezoid arthrodesis for carpal instability showed a high nonunion rate. Four of five failed cases required surgical revision, highlighting potential complications of this surgical technique.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Musculoskeletal System
Background:
- Carpal instability and scaphotrapezial joint arthrosis are common conditions.
- Scaphotrapezio-trapezoid arthrodesis is a surgical option for these conditions.
Purpose of the Study:
- To evaluate the outcomes of scaphotrapezio-trapezoid arthrodesis.
- To identify complications associated with this surgical procedure.
Main Methods:
- Retrospective review of 19 cases undergoing scaphotrapezio-trapezoid arthrodesis.
- Assessment of healing using conventional and computed tomography.
- Analysis of correlation between surgical methods, immobilization time, and outcomes.
Main Results:
- Primary healing failure occurred in five out of 19 hands.
- No correlation was found between surgical techniques or immobilization duration and healing success.
- Four nonunions necessitated surgical revision.
Conclusions:
- Scaphotrapezio-trapezoid arthrodesis presents a significant risk of nonunion.
- The observed complications differ from those typically reported in the literature.
- This method may involve specific adversities requiring careful consideration.
