Complex distal femoral fractures in the fragile elderly patient treated by distal femoral replacement: A report of 3cases. / [Artículo traducido] Fractura de fémur distal compleja en el paciente frágil y anciano tratada mediante reemplazo femoral distal: reporte de 3 casos.

Complex distal femoral fracture (DFF) in the elderly patient is an infrequent but challenging scenario. In these fragile patients, DFF is associated with a high rate of medical complications and mortality. The optimum treatment remains controversial. Our aim is to propose our standard treatment, describe our results and discuss its clinical relevance. We describe 3cases of elderly and fragile patients with multiple comorbidities who suffered a complex DFF after low energy trauma. They were successfully treated through a primary arthroplasty with distal femoral replacement. All the 3patients presented early full weight-bearing mobilization (average time to first ambulation was 5days), good functional outcome (mean knee range of motion was 103°) and short hospital length of stay (mean of 10days). According to our experience, primary arthroplasty with distal femoral replacement could be a good therapeutic option for complex DFF in elderly patients.

La fractura femoral distal (FFD) compleja en el paciente anciano es infrecuente, pero su manejo es un desafío. En estos pacientes frágiles, la FFD se asocia a un elevado riesgo de complicaciones médicas y mortalidad. Su tratamiento óptimo sigue siendo controvertido. El objetivo del estudio es proponer nuestro tratamiento estándar, describir nuestros resultados y discutir su relevancia clínica. Reportamos 3 casos de pacientes ancianos y frágiles con múltiples comorbilidades que sufrieron una FFD compleja a causa de un traumatismo de baja energía. Fueron tratados con éxito mediante un reemplazo femoral distal (RFD). Los 3 pacientes presentaron una movilización precoz con carga completa (la media hasta la primera deambulación fue 5 días), buenos resultados funcionales (la media de rango de movimiento de la rodilla fue 103̊) y una estancia hospitalaria breve (media de 10 días). Según nuestra experiencia, la artroplastia primaria podría ser una buena elección terapéutica para las FFD complejas en los pacientes ancianos.(AU)

Validación de un cuestionario de conocimientos adquiridos por los pacientes tras un taller educativo de artroplastia de rodilla.

INTRODUCTION: Total knee arthroplasty (TKA) is a surgery that aims to restore function and relieve pain in advanced osteoarthritis. The Educational Workshop (EW) for TKA is given to patients in the pre-surgery period to inform them and facilitating their participation in their health process (empowerment). The aim of this study was developing and validating a self-administered questionnaire to evaluate the acquired knowledge after the EW by the patients who will undergo the TKA procedure. MATERIAL AND METHODS: It was a longitudinal and prospective observational study with a sample of TKA candidate patients. The phases for the construction and validation of this ad hoc questionnaire were: Phase 1: A panel of experts who agreed on a final questionnaire of 20 items; Phase 2: Pilot test administered to 47 patients; Phase 3: Final test of 11 items administered to 50 patients, before and after the EW; Phase 4: Re-test, after the EW and 2 weeks after, administered to 58 patients. RESULTS: One hundred and fifty five patients were included. The Cronbach's alpha coefficient for the item's internal consistency of the final questionnaire, 11 items, was 0.78. To reach the criterion validity, in pre-EW the mean number of hits was: 4.92 (SD=1.78) and in post-EW 10.68 (SD=0.55), a difference that had a statistical significance p<.0001, with no overlap in the 95% CI of the mean: 4.46-5.38/10.54-10.82. The test for stability and reliability, re-test, obtained a mean of right answers 10.87 (SD=0.33) and for the re-test of 10.70 (SD=0.59). The correlation of the interclass coefficient for the re-test was 0.99, which corresponds almost to a maximum concordance. CONCLUSIONS: The questionnaire developed in this study is a reliable and easy tool to evaluate the acquired knowledge in the EW for patients who will be TKA operated.

Biomechanical demands of percussive techniques in the context of early stone toolmaking.

Recent discoveries in archaeology and palaeoanthropology highlight that stone tool knapping could have emerged first within the genera Australopithecus or Kenyanthropus rather than Homo. To explore the implications of this hypothesis determining the physical demands and motor control needed for performing the percussive movements during the oldest stone toolmaking technology (i.e. Lomekwian) would help. We analysed the joint angle patterns and muscle activity of a knapping expert using three stone tool replication techniques: unipolar flaking on the passive hammer (PH), bipolar (BP) flaking on the anvil, and multidirectional and multifacial flaking with free hand (FH). PH presents high levels of activity for Biceps brachii and wrist extensors and flexors. By contrast, BP and FH are characterized by high solicitation of forearm pronation. The synergy analyses depict a high muscular and kinematic coordination. Whereas the muscle pattern is very close between the techniques, the kinematic pattern is more variable, especially for PH. FH displays better muscle coordination and conversely lesser joint angle coordination. These observations suggest that the transition from anvil and hammer to freehand knapping techniques in early hominins would have been made possible by the acquisition of a behavioural repertoire producing an evolutionary advantage that gradually would have been beneficial for stone tool production.

Ablation of frequent premature ventricular complex in an athlete.

Premature ventricular complex are common findings in the exam of many athletes. There is no extensive scientific evidence in the management of this situation particularly when associated with borderline contractile function of the left ventricle. In this case report, we present a 35-year-old asymptomatic healthy athlete with high incidence (over 10,000 beats in 24 h) of premature ventricular complex and left ventricular dilatation with dysfunction, which persisted after a resting period of 6 months without training. We performed radiofrequency ablation of the premature ventricular complex focus. After 1-year follow-up, he was asymptomatic without arrhythmia and the left ventricle normalized its size and function as shown by echocardiogram and cardiac magnetic resonance.

Un año de registro de traumatismos graves en Cataluña. Análisis de los primeros resultados / TraumCat: preliminary analysis of a year of severe trauma registry in Catalonia

Objetivo: Evaluar los resultados del primer año de implantación de un registro poblacional hospitalario de traumatismos graves en Cataluña (TraumCat). Método: Un total de 15 hospitales han recogido de forma prospectiva información sobre pacientes traumáticos graves, adultos y pediátricos (menores de 16 años), durante un periodo de un año (del 1 julio 2012 al 1 julio 2013) y la han introducido en un registro informatizado accesible en red. Resultados: Se han registrado 1.106 casos de pacientes con traumatismos de alta energía(12,2% en menores de 16 años). Un 84% de los traumatismos fueron no intencionales en adultos jóvenes. El 54,4% de los traumatismos se originaron en accidentes de circulación y el26,9% en precipitaciones. Un 5,4% correspondían a agresiones. Un 46% de pacientes presentaban un ISS mayor a 15, mientras que el NISS era mayor a 15 en un 51%. La tasa media de mortalidad fue del 10%. Sin embargo, en mayores de 60 años la tasa alcanzó el 25,2%.Conclusiones: TraumCat permite conocer la dimensión y evaluar el proceso asistencial en torno al traumatismo grave en Cataluña. Es preciso avanzar en la consolidación y mejora de esta herramienta como estrategia de monitorización del proceso asistencial y análisis de resultados (AU)

Objective: To analyze results of the first year’s use of the Hospital Population-Based Registry of Severe Trauma in Catalonia (TraumCat).Methods: Fifteen hospitals prospectively collected information on adults and children (< 16 years of age) with severetrauma for 1 year (July 1, 2012 to July 1, 2013). The information was stored in an online database. Results: The registry received 1106 cases of high-energy trauma (12.2% under the age of 16 years) were registered. Eight-four percent of the injuries in young adults were accidental; in the full cohort, 54.4% of the patients were injured in traffic accidents and 26.9% in falls. Personal violence accounted for 5.4%. The Injury Severity Score was over 15 in46% of the patients, and the New Injury Severity Score was over 15 in 51%. Mortality was 10% overall, but in patients aged over 60 years, mortality was 25.2%.Conclusions: TraumCat reveals the scope of severe trauma in Catalonia and facilitates analysis of the process of treatment of these injuries. This tool should be more firmly established and improved as a strategy for monitoring trauma care and outcomes (AU)

Women convicted of a sexual offence, including child pornography production: two case reports.

All available studies addressing the clinical and legal aspects of child pornography have systematically concerned male abusers. The social lens through which women are viewed tends to play down their responsibility in the sexual abuse of children. Unlike men, women rarely abuse children outside the close or family circle. Furthermore, they have frequently been abused themselves in their childhood. To our knowledge, no cases of women charged with sex-related offences, including child pornography, have been described in the literature. The psychopathological characteristics of female sexual abusers and of the two women in our cases tend to suggest that the deliberate downloading of child pornography images by women is unusual, as their deviant behaviour is not related to paedophile sexual arousal It is hypothesized that the act enables women perpetrators to satisfy the sexual urges of their spouse. Sexual abuse by women exists, but the nature of the abuse appears to be specific to the gender of the perpetrator. We present two cases of women charged with sexual offences concerning minors, including the production of child pornography material.

Sudden death due to cerebral malaria: a case report.

Malaria is generally diagnosed ante-mortem. Few post-mortem cases have been described in the literature. Post-mortem cases may present as sudden and unexpected deaths of young individuals rising suspicious of unnatural death, and may therefore be investigated by medical examiners. We present the case of a 24-year-old man who died a few days after returning from a trip to Mali (Africa). Death was attributed to cerebral malaria after a thorough post-mortem investigation. The pathological aspects underlying the fatal outcome are discussed.

Treatment of AO Type C Fractures of the Distal Part of the Humerus through the Bryan-Morrey Triceps-Sparing Approach.

Several alternative approaches have been described to avoid the complications related to the olecranon osteotomy used to treat distal articular humerus fractures. The published experience with the triceps-sparing approach is scant. In this prospective study, a total of 12 patients with an articular humeral fracture were treated using this approach. At a mean followup of 1,7 years, the average range of motion was 112.8° (range from 85° to 135°); the elbow flexion averaged 125.5° (range from 112° to 135°) and the deficit of elbow extension 14.6° (range from 0° to 30°). All the elbows were stable. The Mayo Elbow Performance Score (MEPS) averaged 93.3 (range from 80 to 100). In the present series no failure of the triceps reattachment to the olecranon was found, and all the patients recalled returning to their previous daily life activities without impairment with a satisfactory MEPS. As a conclusion, the triceps-sparing approach can be considered for treating distal articular humerus fractures. We consider that three clinical settings can be more favorable to use this approach: those cases in which a total elbow prosthesis might be needed, cases of ipsilateral diaphyseal fracture, or presence of previous hardware in the olecranon.

Proximal Femoral Nail Antirotation versus Gamma3 nail for intramedullary nailing of unstable trochanteric fractures. A randomised comparative study.

The purpose of this study was to compare the clinical results and the complication rates of a new generation of two intramedullary fixation devices: Proximal Femoral Nail Antirotation® (PFNA) and Gamma3®. We conducted a prospective randomised multicentre trial of 61 patients who underwent a PFNA fixation treatment (31 patients) or a Gamma3 nail (30 patients). We documented the fixation failure complications as well as data of the surgical procedure, the clinical and functional outcomes (the EuroQoL5 questionnaire, the Katz index score, the Short Form 36 (SF-36), and the Harris Hip Score) and the plain radiographic parameters at 3,6 and 12 months follow up. The PFNA and Gamma3 fixation devices were similar in terms of complication rates. The risk for experiencing a postoperative complication after Gamma3 nailing was 40% versus 45% after PFNA fixation. At the 6-month and 1-year follow-up evaluations, there were no significant differences in terms of range of motion, clinical scores and radiological outcomes.

Characteristics of French users of child pornography: description of a cohort subjected to forensic evaluation.

Child pornography is a form of sexual exploitation of children. The virtual aspect of this offence appears to be encouraged by the internet. It is important to know the profiles of the people downloading these images. The aim of our study was to identify the characteristics of people who are drawn to child pornography. Our study was based on psychiatric assessments carried out at the request of the law courts. The feeling of loneliness and poor social integration are evoked by a lot of users of child pornography. Generally, they have no criminal record.

[Evaluation of the results of the treatment of Vancouver B1 periprosthetic fractures and proposed indications for the use of cortical allograft as part of the fixation]. / Evaluación de resultados en el tratamiento de fracturas periprotésicas Vancouver B1 y propuesta de indicaciones del uso de aloinjerto cortical como parte de la fijación.

Currently there is limited information on the indications for the use of cortical allograft for the treatment of periprosthetic fractures on a stable stem. The purpose of this study was to retrospectively evaluate the treatment and the results obtained in this type of fractures and propose a series of criteria for the use of cortical allograft. Between 2003 and 2008 a total of 31 periprosthetic femur fractures were treated at our institution. Twelve of them were classified as B1: 6 were treated with a Dall-Miles (Stryker) system plate and 6 with the same plate supplemented with a structural cortical allograft over the medial cortex of the femur (DM and DM-Allo groups, respectively). An evaluation of the clinical and radiologic results was performed in the latest follow-up available. A patient in the DM-Allo group had rupture of a screw and 10 degrees varization; the fracture healed despite this and the patient had a satisfactory clinical course. The Oxford Hip Score was 9 points lower in the DM group compared with the DM-Allo group, and the EQ-5D health scale was 0.10 better for the DM group. The DM-Allo group had a longer hospital stay and more transfusion-related requirements. We think that the patients with clinical or radiologic criteria of osteoporotic bone may benefit from the use of a cortical allograft to favor healing and increase the bone stock. However, those advantages should be weighed considering the higher risk of surgical-related morbidity associated with the surgical insult.

Fractura de la coracoides, fractura del troquiter y lesión de Hill-Sachs después de un primer episodio de luxación anterior de hombro / Fracture of the coracoid process, the great tuberosity and Hills- Sachs lesion after first time anterior shoulder dislocation

La asociación de fractura de la coracoides, fractura del troquíter y lesión de Hill-Sachs en una luxación anterior de hombro es poco frecuente. Presentamos un caso, que después de un ataque epiléptico, presentaba esta lesión. Tratamos la lesión de manera conservadora, después de reducción cerrada bajo anestesia general. Realizar un diagnostico preciso con unas radiografías rutinarias de urgencias puede ser difícil, así la TAC va a ser de ayuda. Esta rara asociación de fracturas tiene que ser tratada primeramente con una reducción cerrada. Aunque la reducción cerrada de la luxación sea posible, se debe evaluar cada lesión por separado, por una posible indicación quirúrgica de la misma

Fracture of the coracoid's process, the great tuberosity, and Hill-Sachs lesion after first-time anterior shoulder dislocation is a rare association. We present a case with this lesion after epileptic convulsion. We used conservative treatment after closed reduction under general anaesthesia. To make the diagnosis is difficult with the usual radiographs in the emergency department, so CT scan can be helpful. This rare association of injuries are to be treated by primary closed reduction. Even if closed reduction has been possible, surgical options for each separate injury can be considered

[Spinal tuberculosis: early surgical treatment combined with medical treatment]. / Tuberculosis espinal: tratamiento quirúrgico temprano coadyuvante al tratamiento médico.

BACKGROUND: Spinal tuberculosis can produce kyphosis with neurologicaldeficit, despite antibiotic treatment. When there is no response to medical treatment, the recommended procedure is debridementand interbody fusion with bone autograft. The biological characteristicsof Mycobacterium tuberculosis do not prevent osteosynthesisof the infected bone from being performed. PATIENTS AND METHOD: Five patients with spinal tuberculosis and neurological deficitunderwent debridement, interbody fusion and anterior osteosynthesisin addition to medical treatment. In order to ensure stability, posterior fusion was also performed in three patients. All 5 patientsdisplayed weakness and paralysis of their lower extremities, two patients suffered an L4 radiculopathy, one developed paraparesiaand one was excluded due to a short follow-up. Mean value of vertebralkyphosis was 22,8 degrees and mean follow-up was 3,1 years. RESULTS: No patient had septic loosening or progression of the disease. Correction of kyphosis was 104,5% postoperatively and 80,5% atthe end of follow-up. All patients, apart from one with an L4radiculopathy, exhibited neurological recovery. CONCLUSIONS: Anterior instrumentation allows spinal decompression, septic focusdebridement, deformity correction and autologous bone grafting. In severe kyphotic flattening, it is advisable to associate alimited posterior arthrodesis. When pathological fractures appearor there is no response to antibiotic treatment, the combinationof medical and surgical treatment improves patients' outcome.
