Hallux valgus surgery side effects traduction

The first MTP becomes subluxed, what leads to a lateral deviation of the hallux, medial displacement of the distal end of the first metatarsal and bony enlargement of the first metatarsal head .Physical examination should be performed with the patient both seated and standing.With progression, the pull of the adductor hallucis tendon and the intermetatarsal ligament cause the sesmoids to erode the cristae underneath the first metatarsal cuasing the sesmoids to sublux laterally.In this foot deformity, the medial eminence becomes prominent as the distal end of the first metatarsal drift medially and the proximal phalanx deviates laterally.It has a higher prevalence in women (females 30% - males 13%)the elderly (35,7%) .The hallux abducts while the first metatarsocuneiform segments adduct.The severity of the hallux deformity is measured by (A) hallux valgus angle and (B) intermetatarsal 1-2 angle A common problem in people with hallux valgus (pre-operative), is one or more disorders in their gait pattern due to the deformity of the first metatarsophalangeal joint.Each photograph had a hallux valgus angle increased with 15 °.Dysfunctions that may be present: One of the procedures to determine hallux valgus is the use of radiographs. This is the angle formed between the longitudinal bisections of the first metatarsal and the proximal phalanx.In the study by Roddy et al (2007) , they have developed a tool that exists of 5 photographs, instead of 4 photographs which is the case in the Manchester scale.Research has shown that this test is reliable in terms of both re-test and inter-tester reliability (kappa values of 0.77 and 0.86).The angle created between the lines that longitudinally bisect the proximal phalanx and the first metatarsal is known as the hallux valgus angle. Angles of 20 degrees and greater are considered abnormal. The exact etiology is not well established, however, certain factors have been considered to play a role in the development of hallux valgus.

Figure 1: Hallux valgus is a disruption of the normal alignment of the metatarsophalangeal joint.The Manchester scale consists of standardized photographs of four types of hallux valgus: none, mild, moderate and severe. There is a high prevalence of hallux valgus in the overall population (23% in adults aged 18-65 years and 35.7% in elderly people aged over 65 years).When we have an angle less than 15°, there is no sign of hallux valgus.Gender(10x more frequent in women), shoewear (tight pointed shoes), congenital deformity or predisposition, chronic achilles tightness, severe flatfoot, hypermobility of the first metatarsocunieform joint, and systemic disease.

During weight bearing, the deformity is generally accentuated.
