Confronted with increasing problems of financing in health care, some question the relevance of certain interventions of high technicality. Today, the limiting factor for practitioners is not any longer situated at the technical and technological level (the survival of macro replantations is assured in 85-90%) but moves slowly and surely towards the economic level. It is true that medicine has a price and that if a technique is expensive, it should at least be justified at the human level and superior to other less expensive therapeutic options which are available. In this article, we will first focus on the long-term outcome of patients and also on the functional benefit which brings them replantation compared to patients who underwent a regularization of their stump and possibly a reconstruction enabling them to be correctly fitted with a prosthesis.

La première épreuve d’évaluation de l’endurance isométrique des muscles extenseurs du tronc a été décrite par Hansen dès 1964. En 1984, suite à l’étude de Biering-Sorensen, ce test a été largement diffusé dans la littérature sous le nom de « test de Sorensen ». Sa notoriété résulte de son prétendu caractère prédictif de l’occurrence, chez les sujets masculins, d’une lombalgie au cours de l’année à venir. Il s’effectue en décubitus ventral avec le tronc en débord de table, les membres inférieurs étant fixés ; dans cette position le sujet doit maintenir le plus longtemps possible son tronc à l’horizontale. Ce test a été utilisé dans de nombreuses études, de façon standardisée ou modifiée. Il semble discriminatif, reproductible et sans danger, mais les avis divergent toujours dans sa capacité à prédire l’apparition d’une lombalgie, de la présence d’une différence intersexuelle et de l’influence du poids corporel sur le temps de maintien. Si la participation des muscles extenseurs de hanche ne fait plus de doute, leur contribution exacte demeure inconnue. L’influence de facteurs individuels (tel que la motivation) constitue toujours un élément limitant l’interprétation des résultats. Malgré ces inconvénients, le test de Sorensen s’est imposé comme un outil de référence pour apprécier les performances musculaires du patient lombalgique et leur évolution suite à un programme de réhabilitation.

The first test for evaluating the isometric endurance of trunk extensor muscles was described by Hansen in 1964. In 1984, following a study by Biering-Sorensen, this test became known as the “Sorensen test” and gained considerable popularity as a tool reported to predict low back pain within the next year in males. The test consists in measuring the amount of time a person can hold the unsupported upper body in a horizontal prone position with the lower body fixed to the examining table. This test has been used in many studies, either in its original version or as variants. Although its discriminative validity, reproducibility, and safety seem good, debate continues to surround its ability to predict low back pain; in addition, the gender-related difference in position-holding time remains unexplained and the influence of body weight unclear. A contribution of the hip extensor muscles to position holding has been established, but its magnitude remains unknown. The influence of personal factors such as motivation complicates the interpretation of the results. Despite these drawbacks, the Sorensen test has become the tool of reference for evaluating muscle performance in patients with low back pain, most notably before and after rehabilitation programs.
