The authors present an anatomical study of a small flap that may be harvested from any of the palmar intermetacarpal spaces while performing fasciectomy in Dupuytren’s contracture. The flap is diamond-shaped, vascularised by two perforating branches originating from the underlying true digital arteries and may be rotated through 90° to 180° in either direction to provide skin cover and subcutaneous padding over the distal palm and/or the base of the finger.

Background. Posture disorders not treated in early childhood may lead to serious diseases and dysfunctions later. The aim of the study was to assess the incidence of lower limb defects in pre-school children. Material and methods. The study covered 513 children (252 girls and 261 boys) aged 4-6, in chosen kinder­gartens of the Łódź agglomeration . The child’s body posture was assessed using a visual method based on the Kasperczyk scoring scale in own modification. Results. Foot defects occurred in the examined group with a frequency of 85.58% (439/513): in 4-year-olds: 82.59%, in 5- and 6-year-olds: 87.5%. Foot defects were more common in girls in the entire study group (86.9 vs. 84.29%), in 4-year-olds (87.88 vs. 77.45%) and 6-year-olds (88.89 vs. 86.25%), and in boys in the 5-year-olds group (91.14 vs. 83.95%). Defects of the knee joints, including varus and valgus knee, occurred in the study group with a frequency of 52.83% (271/513): in 4-year-olds: 56.72%, in 5-year-olds: 45.63% and in 6-year-olds: 55.26%. Defects were more frequent in girls in the entire study group (54.37 vs. 51.34) and in 4-year-olds (58.59 vs. 54.90%), and in boys in the 5-year-old group (50.63 vs. 40.74%). In the 6-year-olds group, the defects were statistically significantly more common in girls than boys (63.89 vs. 47.5%, p = 0.0442). Conclusion. A high percentage of lower limb defects rate at more than half of the examined pre-school children population is disturbing and requires effective systemic action.

Tibial aplasia is an uncommon lower limb malformation that can occur isolated or be part of a more complex malformation pattern. We describe a 9-year-old boy born after uneventful pregnancy and delivery. Family history was negative for maternal diabetes and other malformations. The patient presented with left tibial aplasia and homolateral prexial foot polydactyly. He also displayed enamel dysplasia and bifid scotum with cryptorchidism. Literature review failed to identify a significant syndromic association between lower limb defects of the tibial type and the genital anomalies reported here. The combination of tibial aplasia with midline genital malformations further supports the hypothesis that the tibial ray development mirrors the morphogenetic process of the radial structures. Accordingly, the malformation pattern observed in the present patient may be pathogenetically explained by an insult occurring during late blastogenesis.

This paper presents a novel method for reference trajectory adaptation in lower limb rehabilitation exoskeletons during walking. Our adaptation rule is extracted from a cost function that penalizes both interaction force and trajectory modification. By adding trajectory modification term into the cost function, we restrict the boundaries of the reference trajectory adaptation according to the patient's motor capacity. The performance of the proposed adaptation method is studied analytically in terms of convergence and optimality. We also developed a realistic dynamic walking simulator and utilized it in performance analysis of the presented method. The proposed trajectory adaptation technique guarantees convergence to a stable, reliable, and rhythmic reference trajectory with no prior knowledge about the human intended motion. Our simulations demonstrate the convergence of exoskeleton trajectories to those of simulated healthy subjects while the exoskeleton trajectories adapt less to the trajectories of patients with reduced motor capacity (less reliable trajectories). Furthermore, the gait stability and spatiotemporal parameters such as step time symmetry and minimum toe off clearance enhanced by the adaptation in all subjects. The presented mathematical analysis and simulation results show the applicability and effectiveness of the proposed method and its potential to be applied for trajectory adaptation in lower limb rehabilitation exoskeletons.
