          Abstract

          Resumen: Introducción: el tratamiento mediante cirugía artroscópica de las lesiones del manguito rotador ha desplazado a la cirugía abierta como primera opción de tratamiento. Existen diferentes técnicas quirúrgicas descritas para tratar las roturas masivas o no reparables. Desde hace unos años se viene utilizando un nuevo dispositivo que consiste en un balón subacromial biodegradable que actúa como espaciador entre la cabeza humeral y el acromion. Este trabajo pretende analizar los resultados de este implante. Material y métodos: realizamos un estudio observacional y retrospectivo de todos los pacientes a los que se les implantó un balón subacromial en nuestro centro entre 2017 y 2019. Se evaluó a los pacientes pre y postoperatoriamente mediante las escalas de Constant, DASH y EVA. Resultados: un total de 43 pacientes cumplieron los criterios de inclusión y el seguimiento mínimo de 24 meses. La puntuación media de la escala DASH pasó de 53.6 en la evaluación preoperatoria a 27.9 en la postoperatoria (p = 0.026). También se obtuvo una mejoría significativa en la escala de Constant, que pasó de una media de 37.9 a 61.8 (p = 0.037). En cuanto a la evaluación del dolor, la EVA media pasó de 7.44 a 3.38 (p = 0.916). En 90% de los pacientes no se objetivaron complicaciones ni necesidad de nuevas intervenciones. Conclusiones: el balón subacromial ha mostrado resultados favorables en nuestra serie de pacientes, por lo que podría suponer una opción válida de tratamiento en pacientes con roturas no reparables del manguito rotador.

          Abstract: Introduction: arthroscopic surgical treatment of rotator cuff tendon injuries has replaced open surgery as the first treatment option. Different surgical techniques have been described for massive or irreparable ruptures, and recently, a new device that consists of a biodegradable subacromial spacer between the humeral head and the acromion has been used. The present study aims to analyse the results of this implant in our experience. Material and methods: we conducted an observational and retrospective study of all patients undergoing subacromial spacer implantation at our centre from 2017 to 2019. Patients were assessed pre- and postoperatively using the Constant, DASH and VAS scales. Results: a total of 43 patients met the inclusion criteria and the minimum follow-up of 24 months. The mean DASH scale score went from 53.6 at preoperative assessment to 27.9 at postoperative assessment (p = 0.026). There was also a significant improvement in the Constant scale from a mean of 37.9 to 61.8 (p = 0.037). In terms of pain assessment, the mean VAS went from a mean of 7.44 to 3.38 (p = 0.916). In 90% of patients no complications or need for further interventions were objectified. Conclusions: the subacromial balloon has shown favorable results in our series of patients, so it could be a valid treatment option in patients with non-repairable rotator cuff tears.

          The results of repair of massive tears of the rotator cuff.

          Massive tears of the tendons of the rotator cuff cause atrophy and fatty degeneration of the rotator cuff muscles and painful loss of function of the shoulder. Repair of massive rotator cuff tears is often followed by retears of the tendons, additional muscular degeneration, and a poor clinical outcome. The purposes of this study were to determine whether a new method of repair of rotator cuff tendons can yield a lower retear rate and a better clinical outcome than previously reported methods, to assess the muscular changes following repair of massive tears of the musculotendinous units, and to correlate findings on magnetic resonance imaging with the clinical results. Twenty-nine massive rotator cuff tears involving complete detachment of at least two tendons were repaired operatively with use of a new laboratory-tested technique in a prospective study. At least two years (average, thirty-seven months; range, twenty-four to sixty-one months) postoperatively, twenty-seven patients were evaluated clinically and with magnetic resonance imaging to determine the clinical outcome, the integrity of the repair, and the condition of the rotator cuff muscles. The age and gender-adjusted Constant score improved from an average of 49 percent preoperatively to an average of 85 percent postoperatively, corresponding to a subjective shoulder value of 78 percent of that of a normal shoulder. Pain-free flexion improved from an average of 92 degrees to an average of 142 degrees, and abduction improved from an average of 82 degrees to an average of 137 degrees. Pain decreased and performance of activities of daily living improved significantly (p < 0.05). The seventeen patients who had a structurally successful repair all had an excellent clinical outcome. Muscle atrophy could not be reversed except in successfully repaired supraspinatus musculotendinous units. Fatty degeneration increased in all muscles. The method of repair of massive rotator cuff tears that was used in this study yielded a comparatively low retear rate and good-to-excellent clinical results; however, the repair did not result in substantial reversal of muscular atrophy and fatty degeneration. Retears occurred more often in patients who had had a shorter interval between the onset of the symptoms and the operation (p < 0.05). Patients who had a retear had improvement of the shoulder compared with the preoperative state, but they had less improvement than did those who had a successful repair.

            Questionnaire on the perceptions of patients about shoulder surgery.

            We developed a 12-item questionnaire for completion by patients having shoulder operations other than stabilisation. A prospective study of 111 patients was undertaken before operation and at follow-up six months later. Each patient completed the new questionnaire and the SF36 form. Some filled in the Stanford Health Assessment Questionnaire (HAQ). An orthopaedic surgeon assessed the Constant shoulder score. The single score derived from the questionnaire had a high internal consistency. Reproducibility, examined by test-retest reliability, was found to be satisfactory. The validity of the questionnaire was established by obtaining significant correlations in the expected direction with the Constant score and the relevant scales of the SF36 and the HAQ. Sensitivity to change was assessed by analysing the differences between the preoperative scores and those at follow-up. Changes in scores were compared with the patients' responses to postoperative questions about their condition. The standardised effect size for the new questionnaire compared favourably with that for the SF36 and the HAQ. The new questionnaire was the most efficient in distinguishing patients who said that their shoulder was much better from all other patients. The shoulder questionnaire provides a measure of outcome for shoulder operations which is short, practical, reliable, valid and sensitive to clinically important changes.

              The validity of pain intensity measures: what do the NRS, VAS, VRS, and FPS-R measure?

              The Numerical Rating Scale (NRS), Visual Analogue Scale (VAS), Verbal Rating Scale (VRS), and Faces Pain Scale-Revised (FPS-R) are valid measures of pain intensity. However, ratings on these measures may be influenced by factors other than pain intensity. The purpose of this study was to evaluate the influence of non-pain intensity factors on the pain intensity scales. We administered measures of pain intensity (NRS, VAS, VRS, FPS-R), pain unpleasantness, catastrophizing, depressive symptoms, and pain interference to 101 individuals with chronic lower back or knee pain. Correlation analyses examined the associations among the pain intensity scales, and regression analyses evaluated the contributions of the non-pain intensity factors (depressive symptoms, and pain unpleasantness, catastrophizing, and interference) to the VAS, VRS, and FPS-R ratings, while controlling for NRS, age, and gender. Although the NRS, VAS, VRS, FPR-S, scales were strongly associated with one another, supporting their validity as measures of pain intensity, regression analyses showed that the VRS also reflected pain interference, the FPS-R also reflected pain unpleasantness, and the VAS was not associated with any of the additional non-pain intensity factors when controlling for NRS, age, and gender. The VAS appears to be most similar to the NRS and less influenced by non-pain intensity factors than the VRS or FPS-R. Although the VRS and FPS-R ratings both reflect pain intensity, they also contain additional information about pain interference and pain unpleasantness, respectively. These findings should be kept in mind when selecting pain measures and interpreting the results of research studies using these scales. The influence of pain interference and pain unpleasantness on VRS and FPS-R, respectively should be kept in mind when selecting pain measures and interpreting the results of research studies using these scales.
