Introduction Hallux abductovalgus (HAV) is a multiplex deformity of the median(a) towboat involving abduction with external rotary motion of the first slam and adduction with internal rotation of the first metatarsal. The displacement of the big toe occurs at the metatarsophalangeal joint, whilst the metatarsal is displaced in the main at the metatarsal / medial cuneiform joint. Deformity is bankers bill by the degree of abduction of the big toe on the metatarsal is greater than 10-12 degrees (Boyd et al. 1994) Occurrence rates for the chequer sketched in the books vary, depending on the age of the participants investigated. Mann and Coughlin reported the frequency of hallux valgus in the adult shoe wearing population as 33% (Mann, RR,et al.1993) Similarly, Dawson et al, observed a rate of 38% in women betwixt 50 and 70 years (Dawson J, et al.2002). In contrast, Menz and churchman report that in a sample of 71 fourth-year adults (aged 75 to 93) 70% were found to have hallux valgus (Menz HB,et al, 2005).(Appendix 1) mint of the hallux valgus In the 19th century, the prevalent understanding of the bunion HAV was that it was purely an elaboration of the soft tissue, first metatarsal head, or both, virtually commonly caused by ill-fitting footgear (Frank et al. 2009).
Gould et al, also reported a higher(prenominal) relative incidence in females versus males, with a ratio of 2:1 to 4:1. Whether this finding indicates a truly change magnitude incidence in the female population or whether it reflects differences in footwear remains to be determined (Frank et al. 2009). Howeve r, surgeons slowly began to blot that bunio! ns could fix as a result of innumerable unalike factors, that they tended to be familial, and that they often were associated with other foot deformities such as work toe, over lap digits, clawed toe. Thus, treatment had varying results, with dispute over whether to remove the overlying bursa alone or in combination with an exostectomy of the medial head (Frank et al. 2009).
