Summary
This study presents a radiographic staging system for basal joint osteoarthritis, guiding surgical treatment selection for thumb pain. It details reconstructive procedures from ligament repair to trapezial resection and implants.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Radiographic Imaging
Background:
- Osteoarthritis of the basal joint of the thumb is a common condition requiring surgical intervention.
- Various reconstructive procedures exist, but a clear rationale for selection is needed.
Purpose of the Study:
- To describe surgical techniques for basal joint osteoarthritis.
- To introduce a radiographic staging system to guide treatment selection.
Main Methods:
- Development of a tonometry applanation radiographic staging system based on trapezial articulation involvement.
- Description of surgical techniques including volar ligament reconstruction, interpositional arthroplasty, and trapezial resection with implant arthroplasty.
Main Results:
- Stage 1: Symptomatic laxity treated with volar ligament reconstruction.
- Stage 2: Treated with volar ligament reconstruction or interpositional arthroplasty based on cartilage condition.
- Stage 3: Ligament reconstruction with interpositional arthroplasty shows good results.
- Stage 4: Trapezial resection with implant arthroplasty or ligament reconstruction.
Conclusions:
- A radiographic staging system effectively guides surgical treatment for basal joint osteoarthritis.
- Specific procedures are recommended based on the stage of trapezial joint degeneration.
- The described techniques offer reliable outcomes for thumb osteoarthritis reconstruction.
