Background/Objectives: Infrared thermography is an advanced technique that detects infrared light emitted by the body to map thermal changes related to blood flow. It is recognized for being noninvasive, fast, and reliable and is employed in the diagnosis and prevention of various medical conditions. In podiatry, it is utilized for managing diabetic foot ulcers, musculoskeletal injuries such as Achilles tendinopathy, and onychomycosis, among others. The primary objective is to analyze the application of thermography in podiatry as a diagnostic evaluation tool. Secondary objectives include evaluating the use of thermography in diagnosing musculoskeletal injuries, determining its role in preventing diabetic foot ulcers and onychomycosis, assessing its utility in sports performance evaluation with plantar orthoses, and reviewing its cost-effectiveness in detecting common foot conditions and deformities. Methods: A systematic review and meta-analysis of the existing literature on the use of thermography in podiatry were conducted. Studies addressing various applications of thermography were included, focusing on its effectiveness, sensitivity, and specificity. Both studies comparing plantar temperature before and after interventions with orthoses and those exploring thermography in diagnosing specific pathologies were analyzed. Results: Ten randomized clinical trials on the use of infrared thermography in podiatric conditions were included, with participant ages ranging from 18 to 80 years (n = 10–223). Treatments for Achilles tendinopathy, diabetic foot ulcers, and peripheral arterial disease were explored. Infrared thermography was utilized to measure thermal changes, evaluate plantar orthoses, and diagnose onychomycosis. The findings underscore the potential of infrared thermography in preventing and diagnosing various podiatric pathologies. Conclusions: Infrared thermography is a noninvasive technique in podiatry that provides real-time imaging without radiation. It is useful for detecting musculoskeletal injuries, diabetic skin ulcers, and onychomycosis and contributes to enhancing sports performance. In conclusion, it is a valuable tool in podiatric practice to optimize therapeutic approaches.

Background: Plantar fat plays a crucial role in protecting and cushioning the metatarsals. Its degeneration is a risk factor for the development of metatarsalgia and, consequently, predislocation syndrome. Objectives: To evaluate the relationship between plantar fat thickness and predislocation syndrome in an adult population, and to determine a possible association between a decrease in forefoot plantar fat and the presence of symptoms. Material and Methods: A retrospective observational study was conducted, including records of patients who visited the podiatry clinic between December 2022 and December 2023. Fifty complete records were selected, divided into two groups, one healthy and one pathological, aged between 18 and 70 years. An ultrasound examination of the plantar area of the second metatarsophalangeal joint was performed to assess the thickness of the fat and plantar plate. Results: The analysis of the 50 records, divided into healthy and pathological groups, reveals significant differences in the thickness of plantar fat and the plantar plate between the two groups. Subjects with predislocation syndrome have a significantly lower plantar fat thickness (0.566 cm) compared to the healthy group (0.941 cm) and also show a greater thickness of the plantar plate (0.359 cm vs. 0.244 cm). Statistical tests confirm these differences with high significance (p < 0.001). The ROC curve shows that plantar fat thickness is a good predictor of predislocation syndrome, with an area under the curve (AUC) of 0.923, emphasizing the utility of this measure in identifying the condition. Conclusions: Preliminary studies suggest that a reduction in plantar fat increases the predisposition to develop predislocation syndrome at the level of the second metatarsophalangeal joint.

Background: Currently, there is no scientific evidence regarding pain in the anesthetic block of the first toe according to the method of application. However, clinical evidence has highlighted the use of the carpule due to the low pain it causes during the administration of the anesthetic. Most studies on anesthesia and pain, especially using the carpule and distraction methods, belong to the field of dentistry. Objective: To compare the pain and effectiveness between the anesthetic block of the first toe using a carpule and syringe with Frost’s H technique and the modified Frost’s H technique. Method: A total of 564 subjects were selected and divided into four groups. Subjects were subjected to experimental conditions (randomization through the Random Allocation Software program 2.0), and divided into group 1 = 138 subjects, corresponding to the block with syringe and Frost’s H, group 2 = 141 subjects, corresponding to the syringe group and modified Frost’s H, group 3 = 141 subjects, corresponding to the carpule group and modified Frost’s H, and group 4 = 144 subjects, corresponding to the carpule group and Frost’s H. The same researcher generated the random allocation sequence, enrolled the participants, and assigned them to the interventions. Each subject was unaware of the anesthetic procedure assigned by the researcher. Outcome parameters were pain after anesthetic infiltration and its effectiveness. Results: The anesthetic block with carpule showed a lower pain score compared to the anesthetic block with syringe (2.8 vs. 5.3; p < 0.001). However, when analyzing effectiveness, a higher efficacy rate was obtained in the anesthetic blocks performed using the modified Frost’s H technique (97.5% vs. 88.1%; p < 0.001). Conclusions: The anesthetic block with carpule and the modified Frost’s H technique is less painful and more effective than the traditional anesthetic block.

Background: Plantar warts, caused by human papillomavirus (HPV), are a common condition that can be painful and resistant to treatment. There are various therapeutic options for managing them, but it is not always clear which are the most effective and tolerated by patients. Among the most commonly used treatments are a zinc and nitric complex (nitrizinc complex), cantharidin, and bleomycin, each with different mechanisms of action and profiles in terms of pain and patient satisfaction. Objectives: We aimed to evaluate and compare the clinical efficacy, post-treatment pain, and patient satisfaction among three common treatments (zinc and nitric complex, cantharidin, and bleomycin) in subjects with plantar warts, as well as identify the most effective and best-tolerated treatment. Materials and Methods: This is a retrospective case series study analyzing 60 records of subjects aged 18 to 40 years diagnosed with plantar warts without systemic diseases or allergies and without any prior treatment. Complete records from 2020 to 2023 were selected. Subjects were divided into three groups according to the treatment received (zinc and nitric complex, cantharidin, bleomycin), and demographic variables, post-treatment pain (measured using the visual analog scale), the number of sessions required, and satisfaction after discharge (evaluated with the Likert scale) were analyzed. Results: Of the 60 subjects included, the group treated with bleomycin experienced higher levels of pain after the first session (mean of 7.1 points on the VAS) compared to the cantharidin group (2.7 points) and the zinc and nitric complex group (1.1 points). However, the bleomycin group required fewer sessions for complete healing (an average of 1.8 sessions), while the nitric acid group needed more (3.4 sessions), with cantharidin falling in between (2.5 sessions). Regarding post-discharge satisfaction, all groups showed comparable scores (between 7.9 and 8.5 points), although cantharidin demonstrated slightly higher satisfaction. A statistical analysis showed significant differences in the number of sessions and post-treatment pain between treatments (p < 0.05) but not in final satisfaction. Conclusions: Although bleomycin treatment is more painful, it is the most effective in terms of reducing the number of sessions required for complete healing. Cantharidin offers a good balance between efficacy and patient satisfaction, while a zinc and nitric complex, although less painful, requires more sessions for complete treatment. Each treatment has specific advantages, suggesting that therapeutic choices should be personalized according to the patient’s needs and preferences.
