A chihuahua with a valgus deformity in the left forelimb. Valgus is a term for outward angulation of the distal segment of a bone or joint. The opposite condition is called varus, which is a medial deviation of the distal bone. The terms "varus" and "valgus" always refer to the direction in which the distal segment of the joint points.
A bunion, also known as hallux valgus, is a deformity of the MTP joint connecting the big toe to the foot. [2] The big toe often bends towards the other toes and the joint becomes red and painful. [2] The onset of bunions is typically gradual. [2] Complications may include bursitis or arthritis. [2] The exact cause is unclear. [1]
Bunion (hallux valgus) deformity is actually part of a complex of anatomical derangements of protruding mass (bunion), buckling of big toe (hallux valgus) and the bone behind it (metatarsus primus varus), displaced sesamoid bones (detrimental to the important walking function of big toe), collapsed metatarsal arch and several other secondary changes that are the domino effects of metatarsal ...
On projectional radiography, the degree of varus or valgus deformity can be quantified by the hip-knee-ankle angle, [7] which is an angle between the femoral mechanical axis and the center of the ankle joint. [8] It is normally between 1.0° and 1.5° of varus in adults. [9] Normal ranges are different in children. [10]
A varus deformity is an excessive inward angulation (medial angulation, that is, towards the body's midline) of the distal segment of a bone or joint. The opposite of varus is called valgus. The terms varus and valgus always refer to the direction that the distal segment of the joint points.
Five studies examined associations between falls and foot disorders. Significant associations were found between falls and plantar fasciitis, corns or bunions and lesser toe deformity (such as Tailor's bunions). The results of these studies show that "Older people who fell were more likely to have foot pain, hallux valgus, and lesser toe ...
Akin osteotomy is a surgical procedure often used in the treatment of hallux valgus deformity, more commonly known as a bunion. [1] A bunion is a bony bump that forms on the joint at the base of the big toe, often resulting in the toe pointing abnormally toward the second toe.
Pathomechanic abnormalities involve shifting of the foot bones, which leads to a paradoxic flat foot, with a varus deformity instead of a valgus. [1] Multiple ligaments and the posterior tibial tendon attach to the navicular. These perform a significant function in acting as a dynamic stabilizer and maintaining bipedal biomechanics. [11]
