Valgus malalignment of the ankle or hindfoot increases pressure over the lateral portion of the tibiotalar and talofibular joints. Due to the noticeable form it’s also referred to as a bunion or ganglion. 2 . External fixation with acute or gradual correction of deformities can be used to safely treat complex ankle deformity.

The average lateral distal tibia angle (LDTA) after age 4 to 5 years is 89° (1° of valgus), with the normal range of 86° to 92° (4° of valgus to 2° of varus); therefore, >4° of valgus … Ankle valgus is an insidious deformity that results in pronation of the foot and medial malleolar prominence.

Valgus deformity results from underdevelopment of the lateral tibial physis, leading to relative overgrowth at the medial side, thus forcing the ankle into a valgus configuration . 20 ° The Anatomic TF Angle = 20 ° valgus. the hindfoot valgus deformity is manually corrected (by inverting the hindfoot) in order to check for true ankle dorsiflexion and achilles contracture. Only 50% of all patients with end-stage ankle OA have normal hindfoot alignment. This happens because the tibia (larger of the two lower leg bones) is tapered at the bottom. Hallux Valgus Deformity (Bunionectomy) Unless the underlying causes of bunions are eliminated, they will only worsen over time. In contrast to foot deformities such as clubfoot and vertical talus, which are generally present at birth, valgus deformity of the hindfoot and/or ankle tends to become more prevalent as a child matures, begins ambulation, and gains weight .
