Thumb Basal Joint Reconstruction
The reconstruction of the thumb’s basal joint is a difficult procedure due to the three different ligaments connecting to the degenerating bone. This bone, the trapezium, is removed during the surgery and a replacement cushion is placed in its spot. A donor tissue from elsewhere in the body, normally a piece of tendon, is used to reestablish a connection between the base of the thumb and index finger. This is a direct connection between the two bones and thus will behave slightly differently post-op.
Additionally, some surgeons hold the tissues and bones in place with a steel pin which may be removed later. Upon completion of the procedure, the patient will keep the thumb immobilized for about four to six weeks and may begin a rigorous therapy program for an additional four to six weeks afterwards.
