Abstract
PURPOSE: This study aims to review the long-term efficacy of the endoscopy-assisted distal soft-tissue procedure (EDSTP) and to see whether operative correction can be maintained for >10 years. METHODS: All hallux valgus cases undergoing EDSTP from 2000 to 2006 were recruited. Preoperative, postoperative, and 10-year follow-up x-rays were analyzed. A pain score from the preoperative and >10-year follow-up was recorded. The American Orthopaedic Foot and Ankle Society (AOFAS) hallux score and Foot and Ankle Outcome Score (FAOS) were measured at the >10-year follow-up. RESULTS: A total of 85 cases met the inclusion criteria with an EDSTP performed between January 2000 and December 2006 and had a follow-up of >10 years. Hallux valgus angle corrected from 25.8° to 11.2° (P < .001), 1,2 intermetatarsal angle (1,2 IMA) improved from 13.5° to 9.5° (P < .001), and the tibial sesamoid position changed from 4 to 1 (P < .001). Pain improved from preoperative 6.5/10 to 0.5/10 (P < .001). AOFAS score was 93.5/100 at >10-year follow-up, and the FAOS was good in all 5 subcategories (range, 72.6-89.3). CONCLUSIONS: Our results show that the EDSTP has good early postoperative results that are maintained for >10 years. It provides good long-term radiological correction, in addition to lasting pain relief and great foot function, using only 5 incisions. LEVEL OF EVIDENCE: Level IV, case series.
