Burn wounds are a complicated process with ongoing psychological and physical issues for the affected individuals. Wound healing consists of multifactorial molecular mechanisms and interactions involving; inflammation, proliferation, angiogenesis, and matrix remodeling. Amlodipine (ADB), widely used in cardiovascular disorders, demonstrated antioxidant and anti-inflammatory effects in some non-cardiovascular studies. It was reported that amlodipine is capable of promoting the healing process by regulation of collagen production, extracellular matrix, re-epithelialization and wound healing through its vasodilation and angiogenic activity. The objective of the current study is to appraise the wound healing capacity of amlodipine-loaded SLN (ADB-SLN) integrated into a hydrogel. The in-vitro characterization revealed that the optimized formulation was nanometric (190.4 ± 1.6 nm) with sufficiently high entrapment efficiency (88 % ± 1.4) and sustained ADB release (85.45 ± 4.45 % after 12 h). Furthermore, in-vivo evaluation was conducted on second-degree burns induced in male Sprague-Dawley rats. ADB-SLN gel revealed a high wound contraction rate and a significant improvement in skin regeneration and inflammatory biomarkers levels, confirming its efficiency in enhancing wound healing compared to other tested and commercial formulations. To conclude, the present findings proved that ADB-SLN integrated hydrogel offers a promising novel therapy for burn wound healing with a maximum therapeutic value.

Distal tibial fractures are common lower-limb injuries and are generally associated with a high risk of postoperative complications, especially in patients with multiple medical comorbidities. This study sought to ascertain the efficacy of retrograde intramedullary tibial nails (RTN) for treating extra-articular distal tibial fractures in high-risk patients. Between January 2019 and December 2021, 13 patients considered at high risk for postoperative complications underwent RTN fixation.

The study included 12 patients with a closed transverse femoral fracture (AO 32a3) treated with dynamization (all the screws distal of the nail were removed) because of delayed healing and followed up for at least 2 years. These patients were evaluated for the presence of bone union, cortex-like sclerosis (corticalization) distal to the nail, and the distance of the corticalization from the joint during follow- up after dynamization.

The aim of the study was to investigate the differences of the reamed versus the unreamed short proximal femoral nailing (PFN), in terms of the duration of surgery and the outcome. The impact of patients and fracture characteristics to the outcome was also evaluated.

In addition, these types of wounds are by definition contaminated. The major challenge in this context for any surgeon remains coverage.
