Plantar Pressure Changes in Hallux Valgus Deformity

Abstract

Hallux valgus deformity is a three-dimensional complex deformity characterized by lateral rotation of the first metatarsophalangeal joint and medial rotation of the proximal phalanx, accompanied by pain, swelling, and the presence of a bunion. Hallux valgus deformity is more common in women than men and its prevalence increases with age. Intrinsic and extrinsic factors are believed to play a role in developing hallux valgus deformity, but the exact cause is still unknown. Plantar pressure, defined as the pressure exerted by individuals on the soles of their feet when standing, has recently been accepted as a reliable biomechanical parameter for investigating and diagnosing various foot disorders. Plantar pressure measurements during standing, walking, or other activities provide detailed information for evaluating deformities involving the ankle, knee, hip, back, and other pathomechanics. They also provide targeted measurement results for monitoring the progression of deformities. Some research groups acknowledge the potential of plantar pressure distribution technology for diagnosing and analysing different foot abnormalities. Pedobarographic analysis, performed in static and dynamic modes, has been widely used in the literature to measure plantar pressure in individuals with hallux valgus deformity. However, in some studies, pressure-sensing insoles have also been used. When examining the literature based on the knowledge accumulated from the past to the present, there is no consensus on the relationship between hallux valgus and plantar pressure, and different views have been put forward.

Halluks Valgus Deformitesinde Plantar Basınç Değişimi

Abstract

Halluks valgus deformitesi, birinci metatarsofalangeal eklemin laterale rotasyonu ve proksimal falanksın mediale rotasyonu ile karakterize, ağrı, şişlik ve bunyonun eşlik ettiği 3 boyutlu kompleks bir deformitedir. Halluks valgus deformitesi, kadınlarda, erkeklere göre daha sık görülmekte olup yaşla birlikte görülme sıklığı artmaktadır. Halluks valgus deformitesinin oluşmasında intrinsik ve ekstrinsik faktörlerin rol oynadığı düşünülmektedir, ancak tam nedeni hala bilinememektedir. İnsanların ayaklarını yere basarken ayak tabanlarına uyguladığı basınç olarak tanımlanan plantar basınç, ayaktaki dağılımları sayesinde son zamanlarda çeşitli ayak bozukluklarını araştırmak ve teşhis etmek için güvenilir bir biyomekanik parametre olarak kabul edilmektedir. Ayakta durma, yürüme veya diğer aktiviteler sırasında yapılan ayak tabanı basınç ölçümleri, ayak bileği, diz, kalça, sırt ve diğer patomekanikleri içeren deformitelerin değerlendirilmesi için detaylı bilgi sağlamaktadır. Aynı zamanda deformitelerin ilerlemesini takip etmek için hedef odaklı ölçüm sonuçları sunmaktadır. Bazı araştırma grupları, ayak tabanı basınç dağılımları teknolojisinin farklı ayak anormalliklerinin teşhisi ve analizi için potansiyelini kabul etmektedir. Statik ve dinamik olarak iki şekilde gerçekleştirilen pedobarografik analiz, literatürde halluks valgus deformitesine sahip kişilerin plantar basıncını ölçmede sık kullanılmıştır. Ancak bazı çalışmalarda plantar basınç ölçen tabanlıklar da kullanılmıştır. Literatür, geçmişten günümüze gelen bilgiler ışığında incelendiğinde halluks valgus ve plantar basınç ilişkisine yönelik tam bir fikir birliği bulunamamakta olup, farklı görüşler öne sürülmektedir.
