What is valgus hindfoot alignment?
Hindfoot valgus refers to malalignment of the hindfoot in which the mid-calcaneal axis is deviated away from the midline of the body. On the DP view, this results in an increase in the angle between the mid-calcaneal axis and the mid-talar axis (talocalcaneal angle) 1.
What causes hindfoot valgus?
Posterior tibial tendinopathy is a common cause of hindfoot valgus deformity. The prevalence of lateral hindfoot impingement has been found to increase with higher grades of posterior tibial tendon tear2. Patients with posterior tibial tendon dysfunction experience both pain and disability.
What does hindfoot varus mean?
Hindfoot varus describes a relatively varus position of the calcaneus which is adducted and rotated under the talus. This is best appreciated on a weightbearing DP foot radiograph as a relative reduction in the angle formed between the mid-talar and mid-calcaneal axes (the talocalcaneal angle).
What is Hindfoot impingement?
Lateral hindfoot impingement (LHI) is a subtype of ankle impingement syndrome with classic MRI findings. Biomechanically, LHI is the sequela of lateral transfer of weight bearing from the central talar dome to the lateral talus and fibula.
How is hindfoot alignment measured?
Fig. 6. Long axial view: hindfoot alignment is measured as the angle between the anatomical axis of the tibia (green line) and the axis of the calcaneus (red line).
How do you measure hindfoot valgus?
B, Hindfoot valgus angle is measured at intersection of line along medial calcaneal wall and line parallel to longitudinal axis of tibia. With progressive hindfoot valgus there is first abnormal contact between lateral talus and calcaneus (red) resulting in talocalcaneal impingement.
How is Calcaneovalgus treated?
Treatment. For most children with typical calcaneovalgus foot, no treatment is necessary, except for some home stretching exercises. The condition usually improves within the first several weeks of life. If there are other causes or associated conditions, those will be approached and managed as indicated.
Can hindfoot valgus be fixed?
The medial sliding osteotomy of the calcaneus is a simple and effective treatment for hindfoot valgus in pediatric patients with severe hindfoot valgus. It provides excellent correction of the deformity, allows early weight bearing, and preserves subtalar motion.
What causes anterior ankle impingement?
A common source of chronic ankle pain among athletes is anterior ankle impingement. This condition, sometimes called “footballer’s ankle,” causes pain in the front of the ankle joint. It’s caused by buildup of scar tissue or bone spurs, usually in response to an acute injury or chronic stress on the ankle.
What is heel valgus?
If you have rheumatoid arthritis it’s fairly common for your heel to drift outwards. This is known as valgus heel. It may not cause any problems if it doesn’t drift too far, but it can be troublesome if your arch flattens as a result. Early treatment of rheumatoid arthritis may slow the development of valgus heel.
What do you need to know about hindfoot valgus?
Hindfoot valgus. Hindfoot valgus refers to malalignment of the hindfoot in which the mid-calcaneal axis is deviated away from the midline of the body. On the DP view, this results in an increase in the angle between the mid-calcaneal axis and the mid-talar axis ( talocalcaneal angle ) 1 . Despite abduction of the calcaneus,…
Which is the correct definition of valgus deformity?
In the hindfoot ( Table 1 ), valgus deformity refers to the widening of the angle between the mid talar and mid calcaneal lines because the mid calcaneal line is deviated away from the midline of the body.
What is the MRI of lateral hindfoot impingement?
Lateral hindfoot impingement (LHI) is a subtype of ankle impingement with classic MRI findings (1). Biomechanically, LHI is the sequela of lateral transfer of weight bearing from the central talar dome to the lateral talus and fibula.
How is radiography used to measure foot alignment?
Radiography is used commonly for measuring foot alignment. In the context of AAFD, measurements are used principally to evaluate longitudinal arch flattening, hindfoot valgus, and forefoot abduction ( Table 1 ).
