摘要

Synovial cysts are benign tissue masses that develop near joints and tendons as a result of fluid leakage. They can be difficult to eradicate, and adjacent tendon and joint surfaces can complicate their treatment. We retrospectively analyzed the data from 4 consecutive patients who had undergone hallux interphalangeal fusion from January 2009 to December 2010. Of the 4 patients, 3 were male and 1 was female, with a mean age of 55 +/- 22 (range 26 to 79) years. These 4 patients had developed painful interphalangeal arthritis with radiographic cystic changes of 1 to 4 years' duration. All patients were treated at a single facility, with surgical fixation of the joint performed by insertion of a single 43-mm headless lag screw across the in-terphalangeal joint. A final postoperative follow-up examination was performed at 22 +/- 7 (range 14 to 30) months postoperatively. The mean American Orthopaedic Foot and Ankle Society hallux functional scores increased significantly from 70.8 +/- 6.1 preoperatively to 90.5 +/- 5.2 postoperatively (p < .01). No complications were observed, and complete interphalangeal joint fusion was observed at a mean of 9.2 +/- 1.2 weeks. In conclusion, these preliminary data suggest that arthrodesis is an alternative effective treatment of symptomatic synovial cyst formation localized to the hallux interphalangeal joint.
