Hallux valgus 15 ans kjeldset

Pain typically is localized to over the prominent medial eminence.There is continued debate over the association of poor-fitting footwear and bunions.Congruency of the first MTP join is important to evaluate on radiographic examination.The structures directly involved in a hallux deformity include the first metatarsophalangeal (MTP) joint, the abductor and adductor hallicus tendons, the hallucal sesamoid complex, the medial and lateral MTP joint capsules, the first tarsometatarsal (TMT) joint and the gastrocsoleus complex.Many experts feel high-heeled shoes with a small toe box or tight-fitting shoes do not cause the deformity.Connective tissue disorders with ligamentous laxity can develop hallux valgus deformities, including Marfan’s syndrome, Ehlers-Danlos syndrome, and Down syndrome.Hallux valgus has numerous recognized etiologies, including biomechanical, traumatic, and metabolic factors.

Some cases are congenital, secondary to the sloping orientation of the first tarsometatarsal joint.Neuromuscular disorders, such as cerebral palsy and Charcot Marie Tooth (CMT), are often associated with rigid bunions.A hallux valgus deformity, commonly called a bunion, is when there is medial deviation of the first metatarsal and lateral deviation of the great toe (hallux).An incongruent joint exists when the toe is in a valgus orientation and the articular surfaces do not align properly or concentrically.The condition can lead to painful motion of the joint and shoe wear difficulty.

Bio-mechanical instability is the most common etiology and is associated with flat feet, gastrocnemius contracture, excessive flexibility of ligaments, forefoot varus, and abnormal bone structure.
