Triple arthrodesis in rheumatoid arthritis.
Academic Article
Overview
abstract
Fifty-five patients with rheumatoid arthritis were treated with 65 triple arthrodeses of the hindfoot from March 1975 through July 1985. Twelve patients (12 procedures) have died, and follow-up evaluation could not be completed on three patients (four procedures), leaving 40 patients (49 procedures) available for clinical and roentgenographic evaluation. There were 32 women and eight men, with an average age at the time of surgery of 50 years. The follow-up period averaged five years. Standard operative technique involved medial and lateral incisions with staple fixation and local bone grafting. Correction of deformity was performed with closing wedge osteotomies. All patients had moderate to severe pain preoperatively and difficulty with ambulation. Postoperatively, 94% of the patients had significant pain relief and 83% had complete pain relief. Ambulatory status was improved in 80% of the patients. Ninety percent were at least community ambulators at the time of review, whereas more than half the patients were limited to household ambulation preoperatively. Complications included four superficial wound infections, all of which responded to local care. One patient required revision surgery for pseudarthrosis, and three patients had progression of ankle disease and required pantalar arthrodeses. There was no significant progression of fore-foot or knee symptoms, however, and there was no progression of ankle symptoms in patients whose hindfeet were corrected to 0 degrees-10 degrees valgus. Triple arthrodesis in the rheumatoid population has a high union rate. Pain relief and ambulation improvement can be expected.
