Study: Arthrodesis most reliable technique to treat hallux rigidus
In a comparison study analyzing the differences between arthrodesis, joint replacement and resurfacing hemiarthroplasty in the treatment of advanced hallux rigidus, researchers all patients had good outcomes at 2-year follow-up, but arthrodesis was the most reliable technique.
“Arthrodesis is still the most reliable surgical procedure; however, it should be used only as a salvage procedure in the treatment of high-grade [hallux rigidus] HR, just as in other joints of the musculoskeletal system,” Mehmet Erdil, MD, and colleagues wrote in the study.
Erdil and colleagues studied 38 patients who underwent arthrodesis, joint replacement or resurfacing hemiarthroplasty for treatment of HR. They evaluated the patients using the American Orthopaedic Foot and Ankle Society-Hallux Metatarsophalangeal Interphalangeal (AOFAS-HMI) scale, VAS, and measuring their metatarsophalangeal range of motion, according to the abstract.
At 2-year follow-up, Erdil and colleagues found significantly improved AOFAS-HMI and VAS scores in all three groups, and they noted no major complications and good functional outcomes. In the arthrodesis group, the VAS scores were significantly improved over the patients who underwent joint replacement and resurfacing hemiarthroplasty. In both of those groups, there were no significant differences in VAS scores, according to the abstract.
