“…Wong et al (2015) attempted to explain the complication of the Lapidus procedure (the 1st MCJ fusion) and found that there was high tensile stress located at the bone graft inferiorly that could lead to non-union of the fusion. Guo et al (2018) found that distal metatarsal osteotomy could reduce the sesamoid displacement and redistributed the plantar pressure whereas the team also compared bandaging, Kirschner fixation, and fiberglass fixation in their later study (Mao et al, 2017). Besides, Brilakis et al (2019) compared the procedure variation of Mitchell's procedure with and without pins and quantified the additional stability contributed by the use of pins.…”

Hallux valgus is a common foot problem affecting nearly one in every four adults. Generalized ligament laxity was proposed as the intrinsic cause or risk factor toward the development of the deformity which was difficult to be investigated by cohort clinical trials. Herein, we aimed to evaluate the isolated influence of generalized ligament laxity on the deterioration using computer simulation (finite element analysis). We reconstructed a computational foot model from a mild hallux valgus participant and conducted a gait analysis to drive the simulation of walking. Through parametric analysis, the stiffness of the ligaments was impoverished at different degrees to resemble different levels of generalized ligament laxity. Our simulation study reported that generalized ligament laxity deteriorated hallux valgus by impairing the loadbearing capacity of the first metatarsal, inducing higher deforming force, moment and malalignment at the first metatarsophalangeal joint. Besides, the deforming moment formed a deteriorating vicious cycle between hallux valgus and forefoot abduction and may result in secondary foot problems, such as flatfoot. However, the metatarsocuneiform joint did not show a worsening trend possibly due to the overriding forefoot abduction. Controlling the deforming load shall be prioritized over the correction of angles to mitigate deterioration or recurrence after surgery.

“…ese methods had been widely used in previous research of HV patients [21,22]. Our results showed that females had a higher incidence rate of HV, and the percentage of female patients was 87.0%, 96.0%, 95.9%, and 94% from group 1 to group 4, respectively.…”

“…At the same time, the peak load rate of Meta2 (Figure 2) and the peak impulse and contact duration of Meta2 and Meta3 (Figures 3(a) and 3(b)) were not significantly different between the four groups. e previous studies had shown greater loading on Meta2 and Meta3 during normal gait of HV patients [21,22,26]. It was also shown that the contact time had the tendency of increase between Meta2-3 and the plantar foot in the gait of HV patients [25,26].…”

Metatarsal pain is a common pathological outcome in patients with a hallux valgus (HV) deformity. However, the relationship between the degree of HV deformity and metatarsal pain has not been systematically examined. The purpose of the present study was to investigate the correlation between metatarsal pain and the degree of HV deformity. Between October 2017 and September 2018, 512 HV patients (944 feet) participated in an evaluation of their HV angle (HVA) using X-ray images. The participants were divided into four groups corresponding to their HVA (<15°, 15° to 20°, 21° to 40°, or >40°). Load rate, impulse, contact duration, and contact area were measured and recorded as dynamic gait parameters using the RsScan system. Data were evaluated using SPSS statistical software. The visual analog scale (VAS) was used to assess metatarsal pain. For the four HV deformity groups, the peak value of impulse and contact duration was concentrated on the second and third metatarsals (Meta2 and Meta3) (P<0.05); contact area was also shown on metatarsals 1, 2, and 5 (P<0.05). Metatarsal pain on Meta2 had the highest VAS score (VAS: 6.57), followed by Meta3 (Mean VAS: 5.72). In the HV > 40° group, the load location on Meta2 was transferred to Meta1. The percent of pain attributed to Meta2 and Meta3 was also increased in this group. These findings illustrated that metatarsal pain was primarily located on Meta2 and Meta3 in the different degrees of HV deformity. This information can provide the location to target for pain relief and help guide further rehabilitation.

“…In patients with HAV, there is an excessive pronation of the subtalar joint or an abnormality of this during any stage of the gait cycle, mainly in the propulsive period. As a result, it produces an abnormal function of the peroneus longus muscle and an instability of the fi rst ray during the propulsion [22][23][24][25][26].…”

Hallux Abductus Valgus (HAV) is a pathology that affects the fi rst metatarsophalangeal joint, in which there is a medial displacement of the metatarsal and a lateral deviation of the hallux, causing joint dysfunction and disability in the patient. There are two types of treatments for this condition (conservative and surgical), and both require an exhaustive biomechanical assessment, since biomechanics are the main cause of this deformity.The main objective of the article is the development of a biomechanical examination and assessment algorithm to be carried out systematically in patients with HAV.
