Sobre a emergência do material coreográfico no trabalho Silent Pact

In this essay, I critically reflect upon a choreographic process that evolved working from an intimate affective trace as a driving force. In Silent Pact (2018), I developed a practice of layering and distilling movement material as an improvisational practice that allows the affects of the dancing experience to be at the centre of the creative process. I define affective trace as an embodied felt-object, an imprint of an intensity that gathers in the dancing. Considering the implications of the perspective of the present in embodied research, I arrive at the idea of thinking dance improvisation as a practice of attending to the emergence of movement forming. Informed by a working approach that involves creating aesthetically stimulating choreographic spaces, I argue for the making of space as a form of choreographic thinking in which both movement and space are produced together (McCormack, 2015) from a process of “affective commotion” (Thain, 1998). I draw on the ideas of relational movement by Erin Manning (2013) and on emergence as an opened-futurity by Elizabeth Grosz (1998) to advance understandings of the experience of sensing as a choreographic tool. In addition, I suggest that Manning’s proposition of placing relation at the centre of analysis offers a model for advancing practices of seeing in movement research. The essay concludes with a reflection on the implications of a model of emergence for ways of doing in artistic practice.

Describo un proceso de estratificación y destilación de material coreográfico como una práctica de improvisación que permite que los afectos de la experiencia de improvisar estén en el centro de la composición. Defino el rastro afectivo como un objeto que se puede sentir en el cuerpo, como la huella de una intensidad que se forma en el acto de movimiento. Al considerar las implicaciones de la perspectiva del tiempo presente en la investigación desde el cuerpo, llego a la posición de pensar la improvisación de la danza como una práctica de atención a la formación del movimiento emergente. Desde una práctica de creación de espacios coreográficos, propongo la idea de la creación del espacio como una forma de pensamiento coreográfico donde el movimiento y el espacio se producen juntos (McCormack, 2015) a partir de un proceso de ‘conmoción afectiva’ (Thain, 1998). Propongo el marco conceptual del movimiento relacional de Erin Manning (2013) y el modelo de ‘emergencia’ como futuridad-abierta de Elizabeth Grosz (1998) como modelos para avanzar en la comprensión de la experiencia sensorial como herramienta coreográfica. Asimismo, sugiero que la propuesta de la relación como eje analítico (Manning, 2013) para desarrollar prácticas de ver en la investigación desde el movimiento. El ensayo concluye con una reflexión sobre el modelo de emergencia y sus implicancias para formas de hacer en la práctica artística.

Radial neck fractures in children: results when open reduction is indicated

BACKGROUND: Radial neck fractures in children are rare, representing 5% of all elbow pediatric fractures. Most are minimally displaced or nondisplaced. Severely displaced or angulated radial neck fractures often have poor outcomes, even after open reduction, and case series reported in literature are limited. The aim of the study is to analyze the outcomes of patients with a completely displaced and angulated fracture who underwent open reduction when closed reduction failed. METHODS: Between 2000 and 2009, 195 patients with radial neck fractures were treated in our institute. Twenty-four cases satisfied all the inclusion criteria and were evaluated clinically and radiologically at a mean follow-up of 7 years. At follow-up, the carrying angle in full elbow extension and the range of motion of the elbow and forearm were measured bilaterally. We recorded clinical results as good, fair, or poor according to the range of movement and the presence of pain. Radiographic evaluation documented the size of the radial head, the presence of avascular necrosis, premature physeal closure, and cubitus valgus. RESULTS: Statistical analysis showed that fair and poor results are directly correlated with loss of pronation-supination (P=0.001), reduction of elbow flexion-extension (P=0.001), increase of elbow valgus angle (P=0.002), necrosis of the radial head (P=0.001), premature physeal closure (P=0.01), and associated lesions (olecranon fracture with or without dislocation of the elbow) (P=0.002). DISCUSSION: In our cases, residual radial head deformity due to premature closure of the growth plate and avascular necrosis were correlated with a functional deficit. Associated elbow injury was coupled with a negative prognosis. In our series, about 25% of patients had fair and 20% had poor results. Outcomes were good in 55% and felt to represent a better outcome than if the fracture remained nonanatomically reduced with residual angulation and/or displacement of the radial head. This study reports the largest series of these fractures with a combination of significant angulation and displacement of the fracture requiring open reduction. We feel that open reduction is indicated when the head of the radius is completely displaced and without contact with the rim of the metaphysis

Brace treatment in juvenile idiopathic scoliosis: a prospective study in accordance with the SRS criteria for bracing studies - SOSORT award 2013 winner.

BACKGROUND: The Juvenile idiopathic scoliosis by age of onset, severity and evolutivity is source of great doubts concerning the purpose and use of conservative treatment. The different clinical experiences leave unsolved the question that arises in applying a conservative treatment when the patients are effectively forward a long growing period, in scoliosis characterized by inevitable evolutivity. The purpose of the present prospective study was to determine the effectiveness of conservative treatment in Juvenile idiopathic scoliosis. METHODS: From 1238 patients treated for idiopathic scoliosis between 1995 and 2012 fulfill the inclusion criteria 163 patients treated with PASB, Lyon brace and Milwaukee. Of these, 113 patients had a definite outcome, 27 have abandoned treatment e 23 are still in treatment. The minimum follow-up was 24 months. Radiographs were used to estimate the curve magnitude (CM) and the torsion of the apical vertebra (TA) at 5 time points: beginning (t1), 6 months after the beginning (t2), intermediate time between t1 and t4 (t3), end of weaning (t4), 2-years minimum follow-up (t5). Three outcomes were distinguished in agreement with SRS criteria: correction, stabilization and progression. RESULTS: The results from our study showed that of the 113 patients with a definite outcome CM mean value was 29.6 ± 7.5 SD at t1 and 16.9 ± 11.1 SD at t5. TA was 13.5 ± 5.4 SD at t1 and 8.5 ± 5.6 at t5. The variations between CM t5-t1 and TA t5-t1 were statistically significantly different. Curve correction was accomplished in 88 patients (77.8%), stabilization was obtained in 18 patients (15.9%). 7 patients (6.19%) have a progression and 4 of these were recommended for surgery. Of 26 patients who abandoned the treatment, at the time of abandonment (12.5 age) have achieved curve correction in 19 cases (70.0%), stabilization in 5 cases (19%) and progression in 3 cases (11%). Of these patients, reviewed at the end of growing, four have been operated on. CONCLUSIONS: Our study confirmed that conservative treatment with brace is highly effective in treating juvenile idiopathic scoliosis, in particular most patients reaching a complete curve correction and only 4.9% of patients need surgery

Histological changes of semitendinosus autograft after anterior cruciate ligament reconstruction in an immature rabbit model

INTRODUCTION: The anterior cruciate ligament (ACL) injury is one of the most common in the knee. Tendons can be used as alternative grafts for ACL repair, with tendon “ligamentization” often reported in literature. The purpose of this study was to evaluate the morphological and histological changes occurring in a semitendinosus tendon (ST) during ACL reconstruction in growing rabbits. MATERIALS AND METHODS: Twenty-one 8-week-old New Zealand white rabbits, weighing about 1500 g underwent reconstructive surgery on the right knee. In two cases the left knee was used to verify the normal microstructure of the ACL and ST in rabbits. The rabbits were then randomly divided into seven groups and sacrificed at 1, 4, 6, 8, 12, 24 and 48 weeks after surgery. The specimens were evaluated under light microscopy to analyze the changes in the intra-articular tract of the graft. The evidence of necrosis, neovascularization and organization of the collagen fibers were investigated. RESULTS: One month after surgery, numerous disorganized fibroblasts and collagenous fibers were identified. A marked reduction of cellular necrosis was observed in the early phase of the neo-ligament healing process. After 4 weeks, these fusiform-like cells became more rounded. By 8 weeks, the collagen fibers had become aligned in parallel with newly formed capillaries and highly differentiated fibroblasts. At 24 and 48 weeks the transplanted tendon differed histologically from both tendon and ligament. CONCLUSIONS: The data of the present study showed that ligamentization did not occur until at least 24 months post-operatively and, during healing, the grafted tendon assumed a unique micro-architecture that was a middle between a tendon and a ligament. The ACL reconstruction in pediatric age has become more frequent in these past recent years. The use of semitendinosus graft with preservation of its distal attachment should be the gold standard in skeletally immature patients
