“…A number of studies deal with the change in the position of the scapula induced by movement or by the mutual position of the glenoid and proximal humerus during the locomotor cycle [10–12]. Studies measuring the variability of this inclination in the standardised rest position are lacking in the literature.…”

“…The variability of scapular inclination in relation to the thorax may be an important factor that distorts the final peri-operative evaluation of glenoid retroversion and may thus affect the surgical outcome. Various works deal with changes in scapular inclination in relation to the thorax during the locomotor cycle [10–12]. Fig.…”
BackgroundPreoperative planning with the aid of imaging methods is a principal factor in successful surgery on the shoulder. This work aims to evaluate the variability of glenoid version, spiralling twist and scapular inclination in relation to the frontal axis. Studies focusing on measuring the variability of scapular inclination in the standardised rest position are lacking in the literature.MethodsWe evaluated 104 CT scans of the shoulder. We measured the glenoid version with respect to the scapular axis at three levels. We measured the scapular inclination angle in relation to the sagittal plane and we determined scapular inclination in relation to the frontal axis. Statistical evaluation was performed using the marginal linear model and parameters were estimated using the generalised least squares method, which enables the dependency of measurements performed on the same subject to be taken into consideration.ResultsThe highest values of retroversion are attained by the glenoid in the cranial section (average -9.96°, range -29.7 to +13.2°). Proof of the spiralling twist is the decline in retroversion at the centre of the glenoid (average -2.09°, range -16.7 to +11.6°).Retroversion decreases further in the inferior direction (average -0.5°, range -20.9 to +17.5°). The average thoracoscapular angle is 45.46°, ranging from 13.1 to 69.0°. The average scapular inclination in relation to the frontal plane is 44.54°, ranging from 21.0 to76.9°.ConclusionsDuring preoperative planning, the surgeon should take into consideration not only the glenoid version in relation to the scapular axis, but also the value of the scapular inclination so as to eliminate possible surgical errors, optimise prosthesis implantation and thus decrease the risk of functional restrictions of the joint.Clinical trial registrationEthics Committee for Multi-Centric Clinical Trials (EK-554/14,29thApril 2014).

“…The possible causative factors are considered to include observer experience, overlying soft tissues, and assessment methods. The variety of assessment methods [10][11][12][13][14], such as differing planes of movement, static state or motion, load conditions, and whether viewing live or on video, may be the major factor in the unreliability of the 4-type treatment classification.…”

Por lo tanto, las luxaciones AC de cualquier grado pueden afectar al ritmo escapular y a su biomecánica.En este artículo se revisa el concepto de disquinesis, cuáles son los criterios para su evaluación y las diferentes clasificaciones.Además, se profundiza en la relación entre la luxación AC y la disquinesis. Los aspectos anatómicos, la presencia aumentada de la disquinesis en el contexto de las diferentes lesiones de la AC y las hipótesis sobre sus causas. Finalmente se comentan los resultados del tratamiento conservador y quirúrgico en el contexto de la luxación AC grado 3 en cuanto a la disquinesis.Type III acromioclavicular separation Rehabilitation Surgical treatment a b s t r a c tThe scapulothoracic and acromioclavicular (AC) joints are inter-related to form the shoulder suspensory complex. Therefore, patients with any kind of AC dislocation may present with biomechanical scapular alterations and suffer scapular dyskinesis.In the present article, the concept of dyskinesis is reviewed, as well as the evaluation criteria and the different types of classifications.The relationship between acromioclavicular joint dislocation and dyskinesis is also assessed.
