A case of rheumatoid thumb carpometacarpal (CMC) arthritis with advanced osteolysis is reported. Although CMC joint arthrodesis was performed, bone union was not achieved, and pain and instability persisted. Therefore, first and second metacarpal bone fusion was performed with satisfactory results. While CMC joint arthrodesis or arthroplasty is typically performed, first and second metacarpal b...

BACKGROUND Analysis of arthrokinematics may have clinical use in the diagnosis of dynamic instability of the thumb and wrist. Recent technological advances allow noninvasive, high-resolution imaging of skeletal (thumb and carpal bones) structures during motion. QUESTIONS/PURPOSES The primary purpose of this study is to define the arthrokinematics, estimated joint contact patterns, and distrib...

We report a case of a carpometacarpal joint dislocation of the thumb associated with trapezium and Bennett's fractures. This combined injury pattern appears to be very rare. To our knowledge, no such case was found in the literature. The patient had open reduction internal fixation with pins and screws, with good functional outcome.

Introduction: Various conservative treatments for first carpometacarpal joint osteoarthritis have been reported. We aim to investigate the short-term effectiveness of conservative management interventions used to improve pain and function for adults with first carpometacarpal joint arthritis in a randomised controlled trial. Methods: A pragmatic 2 2 factorial randomised controlled trial will be...
