Hallux valgus (HV) is a common forefoot deformity for which numerous surgical techniques have been proposed, with the Lapidus procedure representing a powerful and durable solution, especially in cases of moderate to severe deformities and first ray hypermobility. Initially described in the early 20th century, the Lapidus procedure involves first tarsometatarsal joint (TMTJ) arthrodesis and has undergone multiple modifications over time to reduce complications such as nonunion, malunion, shortening, and recurrence. The technique offers triplanar correction, addressing axial, sagittal, and coronal deformity components. Despite its proven corrective potential, the procedure remains technically demanding, and no universal consensus exists on the ideal fixation method or postoperative protocol. Recent developments in fixation strategies—including crossed screws, locking plates, intramedullary nails, nitinol staples, external fixation, and arthroscopic approaches—have aimed to improve stability, union rates, and the possibility of earlier weight-bearing. This narrative review provides a comprehensive overview of the Lapidus procedure, focusing on surgical indications, technical variants, fixation methods, clinical outcomes, and complications, with the goal of offering practical guidance for optimizing surgical decision-making in various clinical settings.

The strength properties of softwood components with bonded joints reinforced with fasteners were investigated and compared. Initial tests of the strength of the glue joints were carried out, with a change in the type of adhesive used. The application method significantly influenced the shear strength of the joint. With the adhesive and pre-bonding systems used, the shear strength of the adhesive joint of pine wood (Pinus silvestris L.) with PUR and PVAC resin was determined. The industrial results were 31% lower than in the shear test of the wooden joint bonded with PVAC glue. In terms of transverse shear force with staples, the joint has a transverse holding force that is higher than components connected with screws or nails. As the number of glue sticks increased, the shear strength of the pine wood increased. The strengths of the joined components in the glue roller method had an intermediate value. They did not differ significantly between the two-row gluing systems used. An increase in the force required to shear the bonded joint was observed for the different adhesive systems, the fasteners used, and their density. Full article

Non-communicable diseases such as cardiovascular diseases, cancers, diabetes, and asthma are increasingly common due to factors like industrialization, urbanization, fast-paced life, stress, sedentary lifestyle, and unbalanced diet in the 21st century. These chronic conditions are a global epidemic, being among the top causes of death worldwide. Preventing these diseases through a nutritious diet is crucial, and scientific studies suggest that appropriate fruit intake, particularly apples, can lower the risk of various health issues. Apples, rich in bioactive compounds, vitamins, minerals, and dietary fiber, offer numerous health benefits. Regular consumption of apples helps reduce the risk of atherosclerosis, coronary artery disease, heart attacks, and diabetes, and also provides anti-asthmatic and anti-allergic effects. Apples aid in detoxification, improve digestion, enhance skin, hair, and nail health, and offer protection against cancers, Alzheimer’s, and Parkinson’s disease. Apples have been a dietary staple for centuries, consumed in various forms like juices, sauces, and ciders. The reviewed article emphasizes the health benefits of apples, highlighting their role in preventing civilization diseases. It also discusses the characteristics of common apple varieties and the impact of thermal processing on their nutritional content. Full article

Background: Foot deformities in children are common, and the majority can be treated conservatively. Nevertheless, there are deformities that require surgical treatment. These include rigid clubfeet, severe forms of pes planovalgus, pes cavus and several more. We retrospectively analysed the pseudarthrosis rate of surgical treatment of foot deformities with transcutaneous K-wire osteosynthesis in neurologically healthy children and adolescents. The aim of the study was to show that the results with K-wires are comparable to those with other osteosynthesis methods in the literature. Methods: A total of 46 paediatric patients aged 6 to 17 years treated between January 2010 and December 2015 met the inclusion criteria. Depending on the diagnosis, different surgical interventions were necessary. In clubfoot and pes planovalgus, representing n = 81, 70% of the whole collective triple arthrodesis with fusion of the talonavicular, calcaneocuboid and subtalar joints or Evans osteotomy was usually performed. Radiographs were taken at least 6 months post-surgery, and bony consolidation of the subtalar, talonavicular (TN), and calcaneocuboidal (CC) joints and the metatarsal I (MT I) osteotomy were assessed. If there was no evidence of fusion at this time, it was considered non-union. Results: In total, 117 arthrodesis procedures with K-wires were performed. Overall, 110 of the arthrodesis (94%) healed, and only 7 joints (6%) showed non-union (subtalar 0%, TN 7.7%, CC 6.5% and MT I 6.7%). All non-unions occurred in subjects with clubfoot deformities. No significant risk factors were observed. Conclusion: This study replicated the good consolidation rates reported in the literature with screws, plates, intramedullary nails or staples in arthrodesis of the adolescent foot in neurologically healthy subjects and confirmed the efficacy of K-wires. The main advantages of transcutaneous K-wire treatment are easy metal removal, lower osteosynthesis material costs and less concomitant damage. Further studies, especially randomised controlled trials, are needed to further investigate this topic. Full article

Wooden nail-stitched crates are widely used for fruit transportation. Bad stapled nails are transformed into severe product damage that creates stains on the crate due to its juice. In consequence, the final customer depreciates the product because the quality product is in doubt. Human visual inspection of badly stapled nails is a non-effective solution since constant criteria are difficult to reach for all of crate production. A system for the in-line inspection based on a conveyor belt of badly stapled nails in stitched crates is presented. The developed inspection system is discussed with the definition of the computer vision system used to identify fails and the description of image processing algorithms. The experiments are focused on a comparative analysis of the performance of five state-of-the-art classification algorithms based on a deep neural network and traditional computer vision algorithms, highlighting the trade-off between speed and precision in the detection. An accuracy of over 95% is achieved if the user defines the nail location in the image. The presented work constitutes a benchmark to guide deep-learning computer vision algorithms in realistic applications. Full article

Leg length discrepancies (LLD) are frequently associated with coronal malalignment. Temporary hemiepiphysiodesis (HED) is a well-established procedure for the correction of limb malalignment in skeletally immature patients. For treatment of LLD > 2 cm, lengthening with intramedullary devices gains increasing popularity. However, no studies have investigated the combined application of HED and intramedullary lengthening in skeletally immature patients. This retrospective single-center study evaluated the clinical and radiological outcomes of femoral lengthening with an antegrade intramedullary lengthening nail combined with temporary HED performed in 25 patients (14 females) between 2014 and 2019. Temporary HED through the implantation of flexible staples of the distal femur and/or proximal tibia was either performed prior (n = 11), simultaneously (n = 10) or subsequently (n = 4) to femoral lengthening. The mean follow-up period was 3.7 years (±1.4). The median initial LLD was 39.0 mm (35.0–45.0). Twenty-one patients (84%) presented valgus and four (16%) showed varus malalignment. Leg length equalization was achieved in 13 of the skeletally mature patients (62%). The median LLD of the eight patients with residual LLD > 10 mm at skeletal maturity was 15.5 mm (12.8–21.8). Limb realignment was observed in nine of seventeen skeletally mature patients (53%) in the valgus group, and in one of four patients (25%) in the varus group. Combining antegrade femoral lengthening and temporary HED is a viable option to correct LLD and coronal limb malalignment in skeletally immature patients; however, achieving limb length equalization and realignment may be difficult in cases of severe LLD and angular deformity, in particular.
