TL;DR: In effect, the procedure is an arthroplasty, either increasing the range of motion at the base of the thumb or improving position of the thumbs with or without increased range ofmotion.
Abstract: Excision of the greater multangular together with portions of the base of either the first, second, or both first and second, metacarpals has been used as an adjunct procedure in the mobilization of the thumb when it is limited by degenerative arthritis, arthrosis as a result of trauma, severe contracture at the base of the thumb as a result of direct injury, or contracture secondary to adjacent injury. Excision of the the greater multangular and release of the soft tissues may sufficient in some instances to correct all contracture, while in others a split-thickness skin graft or abdominal pedicle flap may be necessary to maintain full motion of the thumb web. Improvement in range of motion at the base of the thumb may usually be expected, although occasionally only limited motion may persist, even though there is improvement in the position of the thumb. In effect, the procedure is an arthroplasty, either increasing the range of motion at the base of the thumb or improving position of the thumb with or without increased range of motion.

TL;DR: It seems logical that fusion of bones in the wrist would most probably involve those whose bony growth occurred at identical periods of development, and anatomic facts show that ossification centers appear in different years for each of the carpal bones except the greater multangular and the scaphoid bone, both of which show ossifying centers in the sixth year of life.
Abstract: Congenital fusion of carpal or tarsal bones is a rare anomaly. It may occur independently but usually is associated with synostosis of some of the interphalangeal joints. There are amazingly few English and American papers on the subject. Foreign writers offer varied arguments for their individual theories regarding the cause of this anomaly. I believe that one should accept only the scientific anatomic facts which tend to bear out the theory of arrested or defective development. These anatomic facts show that ossification centers appear in different years for each of the carpal bones except the greater multangular and the scaphoid bone, both of which show ossification centers in the sixth year of life. Because of this embryonic similarity, it seems logical that fusion of bones in the wrist would most probably involve those whose bony growth occurred at identical periods of development. Rochlin 1 in 1928 reported symmetric fusion of

TL;DR: The functional analysis of the tangential fiber layer in the articular cartilage shows that the first carpometacarpal joint is adapted only to movements typical for a saddle-shaped joint.
Abstract: Forty-eight carpometacarpal joints of the thumb (dissecting room material) were investigated roentgenologically and macroscopically. The localization of arthrotic lesions of the articular surfaces of the first metacarpal bone and the greater multangular bone support the view that arthrosis of the first carpometacarpal joint is due primarly to mechanical factors. The opposition movement of the thumb is combined with a pronating rotation of the first metacarpal bone. This rotation leads to an incongruity of the joint and in consequence to an extreme diminuition of the pressure transmitting area. Photoelastic experiments demonstrate that the point-like contact areas are subjected to an extremly high stress. The functional analysis of the tangential fiber layer in the articular cartilage shows that the first carpometacarpal joint is adapted only to movements typical for a saddle-shaped joint.

TL;DR: Eighty cases of peritrapezial arthritis of the thumb treated by Swanson's trapezial implant have been reviewed and the cases of failure by implant instability and its causes are emphasized.
Abstract: Eighty cases of peritrapezial arthritis of the thumb treated by Swanson's trapezial implant have been reviewed by the authors. They advocate a slightly modified technique and emphasize the importance of "varisation" of the implant and of correct resection of the greater multangular bone. Follow-up was at least one year in all cases, maximum 10 years, the mean being 3 1/2 years. Results were judged as very good in 75% of the cases, fair in 20% and poor in 5%. This study emphasized the cases of failure by implant instability and its causes. In 8 cases, abnormal wear of the implant or of the scaphoid bone raises the question of long-term tolerance of silicone implants.
