Impact of Minimally Invasive Intra-Capsular Metatarsal Osteotomy on Plantar Pressure Decrease: A Cross-Sectional Study

Metatarsalgia is a common pathology that is initially treated conservatively, but failure to do so requires surgery, such as the minimally invasive distal metatarsal osteotomy (DICMO). In this prospective study of 65 patients with primary metatarsalgia who underwent DICMO, plantar pressures, America...

Description
Summary:Metatarsalgia is a common pathology that is initially treated conservatively, but failure to do so requires surgery, such as the minimally invasive distal metatarsal osteotomy (DICMO). In this prospective study of 65 patients with primary metatarsalgia who underwent DICMO, plantar pressures, American Orthopaedic Foot and Ankle Society MetaTarsoPhalangeal-InterPhalangeal scale (AOFAS-MTP-IP) and Visual Analog Scale (VAS) were evaluated pre-operatively and post-operatively and there was a subgroup in which an inclinometer was used to observe the importance of the inclination of the osteotomy. The results show a significant reduction in plantar pressures after DICMO surgery without overloading the adjacent radii, especially in the subgroup with an inclinometer to guide the osteotomy. The AOFAS-MTP-IP scale evidenced a marked improvement in metatarsal function and alignment with scores close to normal. The VAS scale showed a substantial decrease in pain after DICMO osteotomy. DICMO, with an inclinometer for a 45° osteotomy, proved to be a safe and effective procedure for primary metatarsalgia, although further comparative studies are needed to confirm its superiority.
