Lesión compleja del codo pediátrico: fractura de cóndilo externo asociada a luxación posteromedial de codo.
2020
espanolAntecedentes y objetivo: La fractura de condilo externo asociada a una luxacion posteromedial de codo es una entidad muy rara, de la cual existen muy pocos casos publicados. Nuestro objetivo es presentar un caso complejo tratado en nuestro centro, el diagnostico, el tratamiento elegido, y el seguimiento a las 9 semanas. Caso clinico: varon de 5 anos con una luxacion posteromedial de codo asociada a una fractura de condilo externo, diagnosticada mediante TC y tratada de forma quirurgica mediante un abordaje anterior sobre el codo, reduccion abierta y osteosintesis con agujas de Kirschner. Resultados: los resultados clinicos y radiologicos a las 9 semanas son excelentes, presentando un…
New intramedullary locking nail for olecranon fracture fixation--an in vitro biomechanical comparison with tension band wiring.
2010
The aim of this study was to determine the difference in displacement of a newly designed intramedullary olecranon fracture fixation device compared with multifilament tension band wiring after 4 cycles and 300 cycles of dynamic continuous loading.In eight pairs of fresh-frozen cadaver ulnae, oblique olecranon fractures were created and stabilized using either newly designed intramedullary olecranon nail or multifilament tension band wiring. The specimens were then subjected to continuous dynamic loading (from 25 N to 200 N) using matched pairs of cadaveric upper extremities. The Wilcoxon test was used to determine statistical differences of the displacement in the fracture gap.After 4 cycl…
Immediate Effects of Vibration Transmitted to the Hand
1981
Summary Three different research projects have been accomplished on the problems: biomechanical behaviour of the hand-arm-system; subjective sensation; physiological changes. Some of the main results were:—the wrist and—with smaller amplifications—the elbow show resonances at low vibration frequencies (10–20 Hz);—with constant acceleration subjective perception decreases with increasing frequency;—application of static grip force—without vibration—causes significant reduction of the skin temperature, which under vibration stress remains at the same lowered level.

The occupation of dental assistants (DAs) involves many health risks of the musculoskeletal system due to static and prolonged work, which can lead to musculoskeletal disorders (MSDs). The aim of the study was to investigate the prevalence of MSDs in DAs in Germany. Methods: For this purpose, an online questionnaire analyzed 406 (401 female participants and 5 male participants, 401w/5m) DAs. It was based on the Nordic Questionnaire (lifetime, 12-month, and seven-day MSDs’ prevalence separated into neck, shoulder, elbow, wrist, upper back, lower back, hip, knee, and ankle), and occupational and sociodemographic questions as well as questions about specific medical conditions. Results: 98.5% …
Effects of electromyostimulation versus voluntary isometric training on elbow flexor muscle strength.
2007
The purpose of this study was to determine whether 7 weeks of standardized (same number and duration of repetitions, sets and rest strictly identical) electromyostimulation training of the elbow flexor muscles would induce strength gains equivalent to those of voluntary isometric training in isometric, eccentric and concentric contractions. Twenty-five males were randomly assigned to an electromyostimulated group (EMS, n=9), a voluntary isometric group (VOL, n=8), or a control group (CON, n=8). Maximal voluntary isometric, eccentric and concentric strength, electromyographic (EMG) activity of the biceps and triceps brachii muscles, elbow flexor muscle activation (twitch interpolation techni…
Dynamische Analyse von Osteosynthesen am Olecranon: ein in-vitro Vergleich zweier Osteosynthesesysteme / Dynamic analysis of olecranon osteosyntheses…
2008
INTRODUCTION The aim of the present study was to develop a test setup with continuous angle alteration to imitate elbow joint motion for the mechanical evaluation of tension band wiring and a newly designed intramedullary nail. MATERIALS AND METHODS The servo-pneumatical test stand worked with a rotational angle-adjusted and a linear force-adjusted engine. The fracture model was dynamically tested under cyclic loading imitating elbow joint motion. In total, 14 fresh cadaver upper extremities underwent olecranon fracture by means of transverse osteotomy and were assigned to two groups: tension band wiring and intramedullary nailing. There was a continuous angle alteration between 0 and 1000 …
L'idrochinesiterapia nel recupero dell'arto superiore dopo allungamento dei flessori del gomito e asportazione di paraosteoartropatia di spalla in so…
2007
La spasticità, oltre a determinare alterazioni dei fisiologici schemi di movimento, siaccompagna a complicanze musoclo- scheletriche per le quali spesso si ricorre all'intervento chirurgico. La riabilitazione, partendo da un'accurata valutazione pre e postoperatoria del malato, da un lato mira al recupero e al mantenimento dell'articolarità, dall'altro al ripristino della motilità volontaria e della destrezza dei movimenti. L'idrochinesiterapia offre evidenti vantaggi nel trattamento di questi soggetti. In questo lavoro si espone la nostra esperienza su un paziente di 38 anni con esiti di trauma cranio-encefalico sottoposto dapprima ad intervento chirurgico sull'arto superiore ed in seguito…
Upper Limb Interventions.
2019
Ultrasound has been reported to be a quick, cheap, and effective imaging modality to guide the interventional procedures in the musculoskeletal system. The use of ultrasound results in increased accuracy of needle placement associated with a reduction of complications. In the upper limb, ultrasound-guided procedures are applied to joints and soft tissues around the shoulder, elbow, wrist, and hand. This article reviews the clinical and technical aspects of the most common procedures performed in this anatomic area.
Olecranon fractures in adults: factors influencing outcome.
2003
In a retrospective, non-randomized study, we reviewed our experience with the operative treatment of olecranon fractures to find out which factors correlate with subjective complaints and functional outcome. A total of 95 consecutive olecranon fractures were operatively treated in our level I trauma institution between 1 March 1992 and 1 March 2000. Medical records and X-rays of all patients were evaluated. Three patients died, 23 were lost to follow-up. Fifty-eight of 69 available patients (84.0%) were reviewed clinically and/or radiologically after a mean time of 36 months. Fracture type, fracture classification, associated lesions, technical correctness of osteosynthesis, age and comorbi…
