The dynamic effects of 5 degrees varus and valgus rearfoot wedging on peak hallux dorsiflexion were investigated in 30 asymptomatic subjects (5 males and 25 females). Statistically significant reductions in peak hallux dorsiflexion were found with rearfoot varus wedging and rearfoot valgus wedging. Furthermore, the reduction in peak hallux dorsiflexion occurring with rearfoot varus wedging was ...

Hallux valgus occurs almost exclusively in shoe – wearing societies. Coughlin and Thompson (2) noting the extremely high prevalence of bunions in American women in the fourth, fifth or sixth decade of life, implicated constricting footwear as a cause of hallux valgus. Likewise, in Japan, Kato and Watanabe (3) noted that the prevalence of hallux valgus in women increased dramatically following t...

BACKGROUND There have been few prospective studies that have documented the outcome of surgical treatment of hallux valgus deformities. The purpose of this investigation was to evaluate the effect of operative treatment of hallux valgus with use of a proximal crescentic osteotomy and distal soft-tissue repair on the first metatarsophalangeal joint. METHODS All adult patients in whom moderate ...

A case of posttraumatic checkrein deformity of the hallux is presented. This deformity is most often caused by scarring of the muscle belly or tethering of the tendon. A 22-year old woman developed a hallux checkrein deformity after a bimaleolar fracture. Intraoperatively, a linear scar tethering the muscle belly to the posterior tibia was observed. Resection of the scar allowed for full flexor...

A survey of 6000 schoolchildren discovered 36 cases of unilateral and 60 cases of bilateral hallux valgus, defined as a metatarsophalangeal angle of more than 14.5 degrees, measured on standing radiographs. Metatarsus primus varus was found not only in the early stages of hallux valgus but in the unaffected feet of children with unilateral hallux valgus. Adduction of the first metatarsal is not...

Hallux valgus is the abnormal lateral deviation of the great toe. The principal cause is biomechanical, specifically the habitual use of footwear which constricts the toes. In this study, descriptions of the anatomical changes of hallux valgus from published cadaveric and clinical studies were used to generate criteria for identifying the condition in ancient skeletal remains. The value of syst...

PURPOSE This study examined differences in ankle motion and plantar pressure between habitually barefoot male (HBM) and habitually shod male (HSM) during vertical jump. METHODS Eighteen habitually barefoot males and twenty habitually shod males volunteered to join the test. Distance between hallux and second toe was measured with Easy-Foot-Scan. Plantar pressure and ankle kinematics were meas...

BACKGROUND Currently, the metatarsophalangeal angle (hallux valgus angle) is measured based on radiographic images. However, using X-ray examinations for epidemiological or screening purposes would be unethical, especially in children. For this reason it is discussed to measure the hallux valgus angle of the margo medialis pedis (medial border of the foot) documented on foot outline drawings or...

Hallux rigidus refers to degenerative arthritis of the first metatarsophalangeal (MTP) joint. Although Davies-Colley provided the first description of the condition in 1887, Cotterill coined the term hallux rigidus to characterize the painful limitation of motion at the first MTP joint.15,18 After hallux valgus, it is the most common affliction of the great toe and the most common form of degen...

We reviewed the outcome of distal chevron metatarsal osteotomy without tendon transfer in 19 consecutive patients (19 feet) with a hallux varus deformity following surgery for hallux valgus. All patients underwent distal chevron metatarsal osteotomy with medial displacement and a medial closing wedge osteotomy along with a medial capsular release. The mean hallux valgus angle improved from -11....
