Treatment of idiopathic postmenopausal osteoarthrosis of the trapeziometacarpal joint with the Epping resection arthroplasty technique.

Surgical treatment of idiopathic postmenopausal osteoarthrosis of the trapeziometacarpal joint with the Epping resection arthroplasty was performed in 57 cases in 49 women. Data show good pain relief (between 58% and 76%), very good subjective results with 89% patient satisfaction and Disability of Arm, Shoulder, Hand (DASH) scores in the lower third of the scale after 35 months' follow-up. Good functional results with respect to radial abduction (51 degrees) and palmar flexion (45 degrees), as well as improvement in strength measurements, could be achieved. Some patients (13%) reported remaining problems with occasional pain during performance of activities of daily life and work. A significant proximal metacarpal migration (31%) without correlation to objective or subjective outcome was found. The Epping procedure has proven to be a valuable alternative procedure to treat idiopathic postmenopausal trapeziometacarpal arthrosis after a midterm follow-up period. Still, careful patient selection is important and sufficient preoperative information necessary.
