Los alumnos trabajaron por equipos con el método de Aprendizaje Basado en la Resolución de Problemas (ABRP). De esta manera, se aseguró la consecución de los objetivos formativos y se dio a conocer la forma de trabajo del médico radiólogo, el proceso de razonamiento diagnóstico, los sistemas de información de los hospitales y en particular del Picture Archiving and Communication System (PACS). PublicationShoulder problems after percutaneous antegrade intramedullary nailing in humeral diaphyseal fractures using contemporary straight third-generation nail(Elsevier, 2023-05-26) Garriguez Pérez, Daniel; Roman Gómez, Julia; Scarano Pereira, Juan Pablo; Ponz Lueza, Virginia; García-Fernández, Carlos; Lópiz Morales, María Yaiza; Marco Martínez, FernandoBackground: Antegrade intramedullary nailing in humeral shaft fracture has been abandoned by certain orthopedic surgeons because of rotator cuff injury caused by first- and second-generation intramedullary nails (IMNs). However, only a few studies have specifically addressed the results of antegrade nailing for the treatment of humeral shaft fractures with a straight third-generation IMN; thus, complications need to be re-evaluated. We hypothesized that fixation of displaced humeral shaft fractures with a straight third-generation antegrade IMN with the percutaneous technique avoid shoulder problems (stiffness and pain) incurred by first- and second-generation IMNs. Methods: This was a retrospective, single-center, nonrandomized study of 110 patients with a displaced humeral shaft fracture between 2012 and 2019 treated surgically with a long third-generation straight IMN. Mean follow-up was 35.6 months (range, 15-44 months). Results: There were 73 women and 37 men with a mean age of 64.7 ± 19 years. All fractures were closed (37.3% 12A1, 13.6% 12B2, and 13.6% 12B3 AO/OTA classification). Mean Constant score was 82 ± 19, Mayo Elbow Performance Score 96 ± 11 and the mean EQ-5D visual analog scale score was 69.7 ± 21.5. Mean forward elevation 150° ± 40°, abduction 148° ± 45°, and external rotation 38° ± 15°. Symptoms associated with rotator cuff disease were present in 6.4%. Evidence of radiographic fracture healing was detected in all but 1 case. One postoperative nerve injury and 1 adhesive capsulitis were present. Overall, 6.3% underwent second surgeries (4.5% were minor surgeries like hardware removal). Conclusion: Percutaneous antegrade intramedullary nailing of humeral shaft fractures with a straight third-generation nail considerably reduced complications related to shoulder problems and achieved good functional results. PublicationImpact of Heart Failure on In-Hospital Outcomes after Surgical Femoral Neck Fracture Treatment(MPDI, 2021-02-22) Marco Martínez, Javier; Bernal Sobrino, José Luis; Fernández Pérez, Cristina; Elola Somoza, Francisco Javier; Azaña Gómez, Javier; García Klepizg, José Luis; Andrès, Emmanuel; Zapatero Gaviria, Antonio; Barba Martín, Raquel; Marco Martínez, Fernando; Canora Lebrato, Jesus; Lorenzo Villalba, Noel; Méndez Bailón, ManuelBackground: Femoral neck fracture (FNF) is a common condition with a rising incidence, partly due to aging of the population. It is recommended that FNF should be treated at the earliest opportunity, during daytime hours, including weekends. However, early surgery shortens the available time for preoperative medical examination. Cardiac evaluation is critical for good surgical outcomes as most of these patients are older and frail with other comorbid conditions, such as heart failure. The aim of this study was to determine the impact of heart failure on in-hospital outcomes after surgical femoral neck fracture treatment. Methods: We performed a retrospective study using the Spanish National Hospital Discharge Database, 2007–2015. We included patients older than 64 years treated for reduction and internal fixation of FNF. Demographic characteristics of patients, as well as administrative variables, related to patient’s diseases and procedures performed during the episode were evaluated. Results: A total of 234,159 episodes with FNF reduction and internal fixation were identified from Spanish National Health System hospitals during the study period; 986 (0.42%) episodes were excluded, resulting in a final study population of 233,173 episodes. Mean age was 83.7 (±7) years and 179,949 (77.2%) were women (p < 0.001). In the sample, 13,417 (5.8%) episodes had a main or secondary diagnosis of heart failure (HF) (p < 0.001). HF patients had a mean age of 86.1 (±6.3) years, significantly older than the rest (p < 0.001). All the major complications studied showed a higher incidence in patients with HF (p < 0.001). Unadjusted in-hospital mortality was 4.1%, which was significantly higher in patients with HF (18.2%) compared to those without HF (3.3%) (p < 0.001). The average length of stay (LOS) was 11.9 (±9.1) and was also significantly higher in the group with HF (16.5 ± 13.1 vs. 11.6 ± 8.7; p < 0.001). Conclusions: Patients with HF undergoing FNF surgery have longer length of stay and higher rates of both major complications and mortality than those without HF. Although their average length of stay has decreased in the last few years, their mortality rate has remained unchanged.

Correlation with screw out of vault penetration and functional situation. Prospective study(Elsevier, 2023-07-25) Lópiz Morales, María Yaiza; Rodriguez Gonzalez, Alberto; Martín Albarrán, Susana; Moreu Gamazo, Manuel; Ponz, Virginia; García Fernandez, Carlos; Marco Martínez, FernandoIntroduction: Baseplate screws have been suggested as a possible cause of suprascapular neuropathy after reverse total shoulder arthroplasty (RTSA). This study aims to investigate the association between screw penetration out of the vault, electromyographic study and the clinical outcomes. Methods: 31 patients who underwent RTSA for cuff tear arthropathy were prospectively enrolled. They were followed up for a minimum of 24 months. All underwent computed tomography 6 months postoperatively in order to determine the extraosseous position of the screws (perforation of the second bone cortex and protrusion into the supra or infraspinatus fossa). Electrodiagnostic evaluation was performed preoperatively and postoperatively to stablish any relation between cortex perforation of the screw and SSN injury. Clinical outcomes pre and postoperatively (Constant score, ranges of motion, and VAS) of patients with and without documented injury were recorded. Results: 14 patients (45.2%) had abnormal preoperative SSN electrodiagnostic study (chronic or disuse injuries) and 6 patients (19.4%) abnormal postoperative study (acute injury. Of these last 6 patients: 2 cases appeared over the pre-existing lesion and 4 appeared over an intact preoperative nerve, all of them affecting the infraspinatus branch of the SSN. Perforation of the second cortex was detected for 60% of superior screws and 40% of posterior screws. The mean lengths of the superior and posterior screws were 30 and 18.2 mm, respectively. Patients with screw perforation of the second cortex were assessed as having a high risk of nerve injury (40% vs. 9.5%). Conclusions: Preoperative SSN injuries do not have a significant clinical impact and do not predispose to an acute postoperative SSN lesion. The Constant Score and VAS scale for patients with acute SSN injuries were not statistically different than those without SSN injury. Extraosseous position of the screw increases the probability of a SSN injury to 31%. This risk is higher with the posterior screw, which leads us to question whether it is really necessary to use it.
