Rigid equinocavovarus (ECV) is a complex foot deformity involving the hindfoot and midfoot, characterized by soft-tissue contractures, bony malalignment, and, in some cases, secondary arthritis. Surgical management of rigid ECV remains challenging because of the severity of the deformity and the need to restore functional alignment and stability. This case series describes the short-term clinical and radiographic outcomes of five patients with rigid ECV who underwent single-stage surgical correction using a modified Lambrinudi osteotomy combined with triple arthrodesis (TA) of the subtalar, talonavicular, and calcaneocuboid joints. The procedure aimed to correct fixed equinus deformity, achieve a plantigrade foot, and provide stable alignment. Patients were followed for 3–6 months postoperatively, with outcomes assessed through clinical examination, the American Orthopaedic Foot & Ankle Society (AOFAS) Ankle–Hindfoot score, and radiographic evaluation. All five patients achieved a pain-free, plantigrade foot, with radiographic evidence of union within 10–12 weeks. The mean AOFAS Ankle–Hindfoot score increased from 40.6 preoperatively to 88.2 at six months. Postoperative radiographs demonstrated satisfactory alignment and fusion. These findings suggest that modified Lambrinudi osteotomy combined with TA may be a promising surgical option for correcting rigid ECV and improving short-term functional outcomes. However, larger studies with longer follow-up periods are warranted to assess the durability of correction and long-term treatment outcomes.
