Methods Fourteen cases of thumb deformities were detected preoperatively by X-ray plain film, angiography and ultrasound examination. The deformities of bone, hemokinesis of thumbs and its blood supply were analysed. The results were compared with their pathological changes during the operation. The deformity was corrected by operations of bone resection, reconstruction of tendon insertion site and preservation of main arteries. Results There were bone deformities 13 cases, abnormal or absent tendon insertion of the main thumb 14 cases. The nutrient of the deformity thumb was supplied by main trunk artery in 11 cases. Conclusion Angiography and ultrasonic examination play an important role in the diagnosis of thumb syndactyly. It can help determine appropriate surgical procedure so that secondary deformities can be prevented after operation. 3 refs,5 figs.展开更多
