We describe the effects of the Austin bunionectomy on plantar pressure distribution and radiographic measurements in the forefoot in 31 subjects (44 feet) with mild-to-moderate hallux valgus deformity and 36 control subjects (36 feet). Plantar pressure measurements before and 24 months after surgery showed peak pressure beneath the hallux reduced to normal values. Peak pressure measurements beneath the first, second, and third metatarsal heads in hallux valgus feet were relatively unchanged after surgery and remained higher than normal values. The operation produced significant decreases in mean preoperative radiographic measurements of hallux abductus, metatarsus primus varus, and first metatarsal protrusion distance in these patients to below-normal values.

Background: Advances in the management of Achilles tendon rupture have led to the development of immediate weightbearing protocols. These vary regarding which ankle-foot orthoses (AFOs) are used and the number of inserted heel wedges used within them. Purpose: This study was conducted to evaluate plantar pressure measurements and temporal gait parameters within different AFOs, using different numbers of heel wedges. Study Design: Controlled laboratory study. Methods: Fifteen healthy participants were evaluated using 3 different AFOs, with 4 different levels of inserted heel wedges. Therefore, a total of 12 conditions were evaluated, in a sequence that was randomly allocated to each participant. Pressure and temporal gait parameters were measured using an in-shoe F-Scan pressure system, and range of movement was measured using an electrogoniometer. Results: Ankle-foot orthoses that were restrictive in design, combined with a higher number of inserted heel wedges, reduced forefoot pressures, increased heel pressures, and decreased the amount of time spent in the terminal stance and preswing phase of the gait cycle ( P = .029, .002, and .001). Conclusion: The choice of AFO design and the number of inserted heel wedges have a significant effect on plantar pressure measurements and temporal gait parameters. The implications of these changes need to be applied to the clinical management of acute Achilles tendon ruptures. This clinical management requires a balance between protected weightbearing and functional loading, requiring further research within a clinical context. Clinical Relevance: The biomechanical data from this research imply that a carbon-fiber AFO, with 1 heel raise, protects against excessive dorsiflexion while facilitating the restoration of near-normal gait parameters. This could lead to an accelerated return to function, avoiding the effects of disuse atrophy. This is in contrast to the rigid rocker-bottom AFO design with a greater number of heel-wedge inserts. However, research within a clinical context would be required to ascertain if these biomechanical advantages translate into a functional benefit for patients. The results should also be considered in relation to the amount of force a healing Achilles tendon can withstand.

Background No detailed comparative studies have been performed regarding plantar pressure changes between proximal dome and distal chevron osteotomies. This study aimed to compare radiographic and plantar pressure changes after distal chevron and proximal dome osteotomies and to investigate the effect of radiographic and plantar pressure changes on clinical outcomes. Methods This study included 26 and 22 patients who underwent distal chevron and proximal dome osteotomies, respectively. Visual analog scale (VAS) and American Orthopaedic Foot & Ankle Society (AOFAS) forefoot scores were used to evaluate pain and functional outcomes. Hallux valgus angle, intermetatarsal angle, talar–first metatarsal angle, and calcaneal inclination angle were measured in the evaluation of radiographic outcomes. Preoperative and postoperative plantar pressure changes were evaluated. Results There were no statistically significant differences between the two groups in age, body mass index, or AOFAS forefoot and VAS scores. In the proximal dome group, the pressure measurement showed significant lateralization of the maximal anterior pressure point in the forefoot (P < .001). In addition, the postoperative calcaneal inclination angle was significantly lower (P = .004) and the talar–first metatarsal angle was significantly higher (P < .001) in the proximal dome group. Postoperative transfer metatarsalgia was observed in one patient (3.8%) in the distal chevron group and five (22.7%) in the proximal dome group (P < .05). Conclusions Proximal dome osteotomy led to more lateralization of the maximum anterior pressure point, decreased calcaneal inclination angle and first metatarsal elevation, and related higher transfer metatarsalgia.

Category: Midfoot/Forefoot Introduction/Purpose: Hallux valgus (HV) is one of the most common forefoot problems. HV is defined as a hallux valgus angle of more than twenty degrees. HV can lead to alterations of the plantar pressure pattern and clinical gait. This study examined the relationship between gait alterations and HV deformities. Methods: We examined 500 residents (161 men and 339 women; >50 years of age) of Miyagawa village in Mie, Japan in 2009, 2011 and 2013. They performed a 6-meter walk test at normal and maximum speed. We examined gait speed, the number of steps, and footprint between patients with normal (HV angle <20; n=350) and HV (HV angle >20; n=150), and between normal-to-mild (HV angle <30; n=436) and moderate-to-severe (HV angle >30; n=64). Their plantar pressure patterns were measured using a gait analyzer (Walk Way MW 1000; Anima, Tokyo, Japan, Figure.1). Statistical analyses were performed using the chi-square test according to sex and use of the hallux ball; the t-test according to age, height, and weight; and logistic regression analysis adjusted for age, sex, and height according to gait speed and the number of steps. P value less than 0.05 was considered significant. Results: With regard to the plantar pressure pattern, the percentage of subjects in the HV group who left a footprint of the hallux ball was significantly lower than that in the normal group. The percentage of subjects in the moderate-to-severe group who left a footprint of the hallux ball was even lower. Analysis of the footprint revealed that the HV group used the hallux ball significantly less during toe-off than the normal group. At both normal and maximum speed, the number of steps and gait speed did not differ significantly between the normal and HV groups. However, when we compared normal-to-mild and moderate-to-severe groups, the number of steps in the moderate-to-severe group was significantly greater than in the normal-to-mild group at maximum walking speed. Conclusion: Analysis of the footprint revealed that the percentage of subjects in the HV group who was able to use the hallux ball during toe-off was significantly less than that in the normal group. The percentage of subjects in the moderate-to-severe group who could use the hallux ball in toe-off was even lower. HV can cause footprint alterations. Moderate-to-severe HV can cause not only footprint alterations but also gait alterations, especially when walking at maximum speed.

The purpose of this study was to determine the intra-observer and inter-observer reliability of physicians on a repetitive basis in making angular measurements of hallux valgus deformities. The hallux valgus angle, the 1–2 intermetatarsal angle, and the distal metatarsal articular angle and the assessment of congruency/subluxation of the first MTP joint were evaluated on a repetitive basis. Physicians were provided with a series of black and white photographs of radiographs with a hallux valgus deformity. Three different sets of photographs randomly ordered were sent at a minimum interval of six weeks to the participants. Participating physicians were extremely reliable in the measurement of the 1–2 metatarsal angle. 96.7% of the photographs were repeatedly measured within a range of 5 degrees or less. The angular measurements to determine the hallux valgus angle were slightly less reliable, but 86.2% of photos were repeatedly measured within a range of 5 degrees or less. In the measurement of the distal metatarsal articular angle, 58.9% of photographs were repeatedly measured within a range of 5 degrees or less. There was a wide range within physician evaluators who recognized very few congruent joints (2 of 21) and those who recognized several congruent joints (11 of 21). Most physicians appeared to be internally consistent in the assessment of MTP congruency; however, some photographs were much more difficult to assess than others. This study validates the reliability of the measurement of the hallux valgus and the 1–2 metatarsal angle. The inter-observer reliability in the measurement of the distal metatarsal articular angle is questioned.
