Surgical therapy of conservatively exhausted rhizarthrosis – total joint replacement or resection arthroplasty? A systematic review.
Clinical Scorecard: Comparative Analysis of Surgical Interventions for Advanced Rhizarthrosis: Total Joint Replacement Versus Resection Arthroplasty – A Systematic Review
At a Glance
Category
Detail
Condition
Rhizarthrosis (osteoarthritis of the thumb carpometacarpal joint)
Key Mechanisms
Idiopathic or post-traumatic cartilage wear due to high rotational and shear forces in the thumb CMC joint
Target Population
Patients typically over 50 years old, predominantly women, with symptomatic thumb CMC osteoarthritis
Care Setting
Orthopedic and hand surgery clinical settings for surgical management
Key Highlights
Rhizarthrosis prevalence increases with age, affecting up to 39% of women by age 80.
Third-generation dual-mobility prostheses show superior mid-term outcomes with low revision rates.
Systematic review evidence indicates prosthetic treatment offers faster pain relief and functional recovery than trapeziectomy-based procedures in the short term.
Guideline-Based Recommendations
Diagnosis
Clinical assessment of load-dependent thumb CMC joint pain and functional impairment.
Two-plane radiographs of the thumb to identify joint space narrowing, sclerosis, osteophytes, and subluxation.
Use Eaton and Littler classification for staging rhizarthrosis.
Consider CT for complex anatomy or preoperative planning; MRI reserved for specific indications.
Management
Surgical options include total joint arthroplasty with modern prostheses or trapeziectomy with/without ligament reconstruction or tendon interposition.
Third-generation dual-mobility prostheses (e.g., TOUCH®) recommended for improved functional outcomes and lower complication rates.
Resection arthroplasty remains an option but shows slower recovery and less favorable short-term outcomes compared to prostheses.
Monitoring & Follow-up
Postoperative assessment of pain (VAS), functional scores (DASH, QDASH, MHOQ), range of motion, grip and pinch strength.
Regular follow-up to detect implant loosening, instability, or need for revision surgery.
Long-term monitoring for prosthesis survival rates and functional maintenance.
Risks
Early prostheses had high rates of loosening and dislocation; modern designs reduce these risks significantly.
Potential complications include trapezial cup loosening and polyethylene wear leading to instability.
Resection arthroplasty may result in prolonged pain and functional impairment during recovery.
Patient & Prescribing Data
Patients with advanced symptomatic rhizarthrosis, predominantly women over 50 years old.
Modern thumb CMC prostheses provide faster pain relief, improved function, and better range of motion within 6 to 12 weeks postoperatively compared to resection arthroplasty.
Clinical Best Practices
Use standardized clinical and radiological criteria including Eaton and Littler classification for diagnosis and staging.
Prefer third-generation dual-mobility prostheses for surgical management to optimize outcomes and minimize revisions.
Implement comprehensive postoperative monitoring of pain, function, and implant integrity.
Consider patient-specific factors such as age, activity level, and anatomical complexity when selecting surgical intervention.
