Excision of the trapezium with Gelfoam interposition was performed in 35 thumbs, 34 of which were evaluated after an average 5 years. Twenty-four patients had unilateral procedures. The follow-up examination included a standardized questionnaire and clinical and radiological examinations. Pain relief was achieved in all cases. The patients considered that 32 of their operated hands had improved function, while two had not improved. All patients were satisfied with the final postoperative result. Adduction of the thumb to the index finger, and opposition to the tip of the little finger was possible in all cases. Weakness, in comparison to the other thumb, of lateral pinch (71%; P=0.0001), tip pinch (74%; P=0.007), and grip strength (85%; P=0.006) were observed. The first web span was preserved in all hands. Calculation of the trapezial space ratio demonstrated only slight, insignificant shortening (7%; P=0.06) of the thumb ray. No significant correlations between the postoperative trapezial space ratio and lateral pinch strength, tip pinch strength, and grip strength were observed. We conclude that excision of the trapezium and Gelfoam interposition has no specific complications and is a reliable surgical treatment for osteoarthritis of the trapeziometacarpal joint.
