Summary
Cementless ball and socket trapeziometacarpal arthroplasty effectively treats osteoarthritis, providing significant pain relief and functional improvement for most patients. Revision surgery was needed for 13% of cases, but outcomes remained positive.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
- Reconstructive Surgery
Background:
- Trapeziometacarpal (TMC) osteoarthritis significantly impacts daily activities and quality of life.
- Surgical interventions aim to restore function and alleviate pain in advanced TMC osteoarthritis.
Purpose of the Study:
- To evaluate the efficacy and outcomes of cementless ball and socket TMC arthroplasty for Eaton and Littler stage II and III osteoarthritis.
- To assess clinical results, functional improvements, and radiographic findings associated with this arthroplasty technique.
Main Methods:
- A cohort of 36 patients (42 joints) underwent cementless ball and socket TMC arthroplasty between 1986 and 1992.
- Clinical outcomes were evaluated using pain relief, functional improvement, and specific functional tests.
- Radiographic monitoring assessed for radiolucent lines and loosening of implant components.
Main Results:
- 79% of evaluated patients reported good to excellent pain relief and functional improvement.
- All functional tests showed improvement post-surgery, with dramatic relief in daily living complaints.
- Radiolucent lines were present in 52% of monitored implants, and radiographic loosening in 32%, without correlation to clinical outcomes.
Conclusions:
- Cementless TMC arthroplasty is a viable surgical alternative to arthrodesis for selected TMC osteoarthritis patients.
- The procedure offers advantages in maintaining joint motion and stability.
- Failures can be salvaged with ligament reconstruction tendon interposition arthroplasty.
