Herbivore-induced grow volatiles mediate safeguard regulation in maize foliage although not within maize roots.
With the exception of hamstring activation, lower limb electromyography measures were largely similar between ligament-reconstructed and matched control subjects, which was in contrast to the clinical findings. This result brings into question the significance of neuromuscular function at this long-term follow-up but raises new questions regarding the role of symmetry and pre-injury risk.

Ankle and hindfoot malalignment is a common finding in patients suffering from post-traumatic ankle osteoarthritis. However, no studies have addressed the effect of concomitant foot deformities on intrinsic foot kinematics and kinetics. Therefore, the objective of this study was to investigate the effect of ankle and hindfoot malalignment on the kinematics and kinetics of multiple joints in the foot and ankle complex in patients suffering from post-traumatic ankle osteoarthritis.

Twenty-nine subjects with post-traumatic ankle osteoarthritis participated in this study. COX inhibitor Standardized weight-bearing radiographs were obtained preoperatively to categorize patients as having cavus, planus or neutral ankle and hindfoot alignment, based on 4 X-ray measurements. All patients underwent standard gait assessment. A 4-segment foot model was used to estimate intrinsic foot joint kinematics and kinetics during gait. Statistical parametric mapping was used to compare foot kinematics and kinetics between groups.

There were 3 key findings regarding overall foot function in the 3 groups of post-traumatic ankle osteoarthritis (i) altered frontal and transverse plane inter-segmental angles and moments of the Shank-Calcaneus and Calcaneus-Midfoot joints in the cavus compared to the planus group; (ii) in cavus OA group, Midfoot-Metatarsus joint abduction sought to compensate the varus inclination of the ankle joint; (iii) there were no significant differences in inter-segmental angles and moments between the planus and neutral OA groups.

Future studies should integrate assessment of concomitant foot and ankle deformities in post-traumatic ankle osteoarthritis, to provide additional insight into associated mechanical deficits and compensation mechanisms during gait.

Hallux Valgus associated with medial column instability (disrupted Meary's line) can be corrected either with Lapidus-Akin or Scarf-Akin procedure. This study compares these two procedures to ascertain if type of surgical procedure performed affects the correction achieved and recurrence rate at 6 months following operative intervention.

This is a retrospective case series that reviews the incidence of early recurrence of Hallux Valgus deformity in 60 patients with an associated disrupted Meary's line who underwent either a Scarf-Akin osteotomy (n = 30) or a Lapidus-Akin procedure (n = 30) between January 2014 and January 2020. Radiographs, operative and clinical notes were utilized to determine degree of correction and recurrence of deformity at 6 months between both groups.

The study found a 47% higher recurrence rate in the Scarf-Akin osteotomy group compared to the Lapidus-Akin group at 6 month follow up. This result was statistically significant with a p-value of 0.002 (95% CI 7-49%). Lapidus-Akin procedure was also found to be superior to the Scarf-Akin procedure in achieving a better degree of correction in the Hallux Valgus angle by an average of 11 degrees.

A disrupted Meary's line is a risk factor for recurrence of Hallux Valgus deformity. The authors recommend that Lapidus-Akin procedure has a significantly reduced recurrence rate compared to a Scarf-Akin osteotomy in Hallux Valgus with disrupted Meary's line.

Four subjects (2 males and 2 females; 34-61 years old) were operated on their ankles due to chronic and deep OLT-Hepple grades 4 or 5 (1.8-2.2 cm2). Three subjects had OLT on the medial central trochlea, and 1 had a combined medial and lateral lesions. OLT were exposed through medial malleolus osteotomy, with an additional lateral arthrotomy in the combined lesions. Bi-phasic porous osteochondral scaffolds (single implant or 2 implants) were implanted in a press-fit manner using a designated surgical toolset. Treatment outcome was followed clinically (Foot and Ankle Outcome Score, EQ-5D 3L, Tegner activity scale) and by medical imaging (radiographs, magnetic resonance imaging) from 18 to 32 months. All Foot and Ankle Outcome Score values increased from preoperative to final follow-up values (Symptoms 62 to 71, Pain 53 to 84, ADL 60 to 89, Sport 19 to 65, and QoL 18 to 47). EQ-5D 3L increased from 0.59 to 0.76, and Tegner activity values increased from 1.5 to 3. Kellgren-Lawrence ankle radiographic scores remained stable (2 to 2). Postoperative MR evaluation demonstrated cartilage defect fill of 75% to 100% respect to the native cartilage in 3 subjects (4 OLTs), while 1 lesion was filled 25% to 50%. No graft related serious adverse events or graft failures were reported. The use of a bi-phasic osteochondral biodegradable aragonite-based scaffold in the treatment of complex OLT during the reported period presented positive and promising clinical and radiologic outcome, without serious adverse events or graft failures.
