Study on Basal Joint Arthritis Prospective

The data in this prospective registry will be used 1) to define which surgical and nonoperative techniques are most effective at providing pain relief, restoring function, are cost effective, and patients are satisfied with their outcomes; and 2) to design focused clinical questions regarding the optimal treatment of basal joint arthritis of the thumb in future randomized controlled trials. There are no interventions or changes in patient care associated with this study.

Inclusion Criteria: * Patients who have symptomatic basal joint arthritis. * Patients who are capable of providing informed consent. Exclusion Criteria: * Patients younger than 18 years old at the time of enrollment. * Patients with neuromuscular disease affecting the operated hand, not caused by the CMC operation. * Patients with known inflammatory arthritic conditions, such as rheumatoid or psoriatic arthritis. * Patients with a history of or current infection of the basal joint of the affected hand. * Patients who are demented or are unable to provide informed consent. * Patients unable to comply with study guidelines. * Patients who have metacarpophalangeal joint hyperextension are NOT excluded. These patients will be followed and if they receive a capsulodesis or other procedure at the MCPJ at the same time as their basal joint arthroplasty this will be noted in their data records.
