| Popis: | Category: Bunion; Midfoot/Forefoot Introduction/Purpose: Lapidus procedure (LP) is a powerful technique to correct hallux valgus (HV) deformities, with good long-term outcomes. However, postoperative complications may arise, as undercorrection of the deformity, nonunion, elevation and shortening of the first metatarsal (M1). The objective of this study was to correlate M1 shortening with transfer metatarsalgia, and clinical and functional outcomes in patients who underwent the LP. Methods: a retrospective review of 29 patients (36 feet) who were submitted to the LP for HV correction was performed. The average follow-up was 20 months. M1 length was analyzed using the Relative First Metatarsal Length (RML) measurement (Figure 1). When M1 shortens in relation to the second metatarsal, the RML measurements increase. The intermetatarsal angle (IMA) and hallux valgus angle (HVA) were also measured. Clinical and functional analyses were based on the VAS for pain, AOFAS, LEFS and SF-12 health survey. SF-12 is divided into physical and mental health composite scales (PCS-12 and MCS-12, respectively). Transfer metatarsalgia diagnosis was based on the clinical exam. Radiographic, clinical and functional measurements were compared using paired Wilcoxon signed-rank test and Student t test. Interobserver reliability of RML measurements was calculated using Intraclass Correlation Coefficients (ICC). A linear regression was performed to assess the correlation between RML and the clinical and functional questionnaires. Results: There was a significant M1 shortening of 2.28mm after the LP (p |
