Rheumatoid Forefoot Reconstruction in the Nonrheumatoid Patient.

Abstract

Recurrent pain and deformity following forefoot surgery can cause significant patient disability. In patients with rheumatoid arthritis, first metatarsophalangeal (MTP) joint arthrodesis with lesser metatarsal head resections-termed the rheumatoid forefoot reconstruction-has been shown to be a reliable operation for pain relief and deformity correction. Limited data, however, have been published on outcomes of the same forefoot reconstruction operation in the nonrheumatoid patient. Here, we describe our experience with this procedure in patients without rheumatoid disease, hypothesizing improved clinical and radiographic outcomes following surgery. Following chart review and reviewing billing codes, we retrospectively identified patients without a diagnosis of rheumatoid arthritis who underwent first MTP arthrodesis with lesser metatarsal head resections. Phone surveys were conducted to assess clinical outcomes including pain and patient satisfaction. Preoperative and postoperative radiographs were reviewed for 1, 2 intermetatarsal angle (IMA), hallux valgus angle (HVA), second MTP angle (MTP-2), and lesser MTP alignment (in both sagittal and axial planes). Postoperative radiographs were assessed for radiographic union. We identified 14 nonrheumatoid patients (16 feet) who underwent forefoot reconstruction. Of those, 13 patients (15 feet) were successfully contacted via follow-up phone survey at an average of 44.3 months postoperatively (range: 20-76 months). Mean postoperative satisfaction scores were 9.0 (out of 10). No patients required reoperation at final phone follow-up. Pain scores significantly decreased from 6.2 preoperatively to 1.9 postoperatively ( P <.001). Radiographic parameters (1,2 IMA, HVA, MTP-2, and lesser MTP alignment in the sagittal plane) improved with surgery ( P <.05), and all 16 feet achieved union of the first MTP arthrodesis. With decreased pain, high satisfaction rates, and improved radiographic parameters, first MTP arthrodesis coupled with lesser metatarsal head resection was a viable option for nonrheumatoid patients who failed prior attempts at forefoot reconstruction or have chronic forefoot pain with deformity.
