Item Cost effectiveness of different techniques in hallux valgus surgery.(Elsevier, 2016) Wagner, Emilio; Ortiz, Cristián; Torres, Karen; Contesse, Ivan; Vela, Omar; Zanoll, DiegoBACKGROUND: Different surgical techniques are available to correct each type of Hallux Valgus (HV) deformity, and all present similar good results. No information is available relative to the cost of each technique compared to their individual success. OBJECTIVE: To determine the cost-effectiveness-ratio (CER) of five different techniques for HV. METHODS: We included 245HV surgeries performed in 179 patients. The severity was defined according to radiological parameters. For mild to moderate HV we included the Chevron, Modified-Scarf and Ludloff techniques; for severe HV: either Poscow-osteotomy or Lapidus-arthrodesis fixed with plates or screws. Weighted costs were estimated. CER was expressed in $US dollars per AOFAS-point. RESULTS: The lowest weighted cost was observed for the Chevron-group, and the highest weighted cost was observed in the Poscow-osteotomy and Lapidus-arthrodesis fixed with plate groups. The AOFAS-score improvement was higher in the Chevron and Modified-Scarf groups. The CER found for Chevron and Modified-Scarf techniques were significantly less than for Poscow and Lapidus-techniques. CONCLUSION: Cost-Effectiveness-Ratio was lower, and therefore better, in the groups with mild to moderate deformities operated with Chevron or Modified-Scarf techniques. In severe HV, the three techniques investigated presented similar CER. CER analysis is an additional factor that can be included in the decision making analysis in hallux valgus surgery.
