“…1 The scarf osteotomy, which was first reported in 1926, is used to correct mild to severe hallux deformities. Although the clinical results are satisfactory, [2][3][4] several complications of a mechanical nature have been reported, 5 notably fracture, troughing and stiffness, 1,[6][7][8][9][10] with percentages as high as 10, 35 and 41.7%, respectively. Troughing is defined as the collapse of the cortex of the dorsal half of the osteotomy and wedging into the softer cancellous bone, with or without rotation of the plantar half of the first metatarsal shaft.…”

Purpose Finite element (FE) analysis and clinical follow-up were used to evaluate the efficacy of modified scarf osteotomy for moderate-to-severe hallux valgus (HV). Method We retrospectively evaluated 42 patients (44 feet) who underwent modified rotational scarf osteotomy for moderate-to-severe HV at our institution between January 2010 and January 2019. Radiological indicators and subjective scores were recorded at different time points. To compare the results and elemental characteristics, a FE model of the metatarsophalangeal (MTP) joint that included anatomically realistic geometrical and structural characteristics was built. The biomechanical features and correction differences in dynamic loads as well as the incidence of troughing were estimated. Results Both the hallux valgus angle (HVA) and intermetatarsal angle (IMA) showed significant improvement 6 weeks postoperatively ( p < 0.05); additionally, the HVA increased from 6 weeks postoperatively to the last follow-up, while the IMA showed no significant changes ( p > 0.05). The subjective scores significantly improved from the preoperative period to the last follow-up. The percentages of troughing and recurrence were remarkably low in our pilot study because of the innate stability of the modified rotated fixation. Conclusion Our preliminary findings suggest that modified rotational scarf osteotomy offers sufficient stability, correct HV deformity effectively, and good clinical outcomes for moderate to severe HV.
