Basal Joint Arthritis A Review of Pathology, History, and Treatment

The basal joint is a collection of articulations at the base of thumb that serve an important function in the overall dexterity of the hand. The unique anatomy of the basal joint provided many evolutionary advantages to the human hand, but also made this joint susceptible to arthrosis and degenerative changes. Surgical treatment of basal joint arthritis has continued to evolve since it was first described in 1949, including excisional arthroplasty, tendon interposition, ligament reconstruction, implant arthroplasty, and arthroscopy. A review of the pathoanatomy, history, and surgical treatments are assessed including a critical review of the literature.
