It is thought to be a primary factor in the pathogenesis of many common pedal ailments, including plantar fasciitis, hallux valgus, metatarsalgia, Achilles tendinopathy, fatigue of the anterior extensor muscles, ulcers, and a variety of other pathologies that are seen in clinics daily. 3-5Īlthough milder than the spastic neuro-induced cases of equinus, the gastrocnemius contracture in the non-neurologically impaired population is being highlighted as a source of deformity that will lead to excessive strain throughout the foot. 1,2 Practitioners, however, are beginning to emphasize a form of soft tissue equinus that occurs as a result of an isolated contracture of the gastrocnemius muscle in the healthy adult population. Equinus of the foot is the most common deformity in children with spastic cerebral palsy and, as early as the 1920s, Swedish orthopedic surgeon Nils Silfverskiöld advocated the use of a gastrocnemius recession as a way to treat cerebral palsy patients who suffered from a contracture of the posterior calf muscles. Whitaker DPM, FACFASĮquinus has been investigated extensively throughout the literature, and can be described as an inability to dorsiflex the ankle joint enough to allow for normal pain-free ambulation.
Although milder than the spasticity-induced cases of equinus, limited ankle dorsiflexion in the non-neurological population is increasingly recognized as a source of excessive strain throughout the foot and a factor in the pathogenesis of many foot conditions.īy Nicholas V.
