Reparación de roturas del ligamento cruzado anterior con sistema aperfix / Anterior cruciate ligament reconstruction with the aperfix system

Introducción: la reconstrucción del Ligamento Cruzado Anterior (LCA) con isquiotibiales resistiría 1216 N, con una pérdida extensora de sólo un 3%. Nuestro objetivo es revisar nuestra experiencia con este procedimiento con el sistema Aperfix®. Material y métodos: Estudio observacional, descriptivo y retrospectivo. Tamaño muestral de 224 casos, seguimiento mínimo de 12 meses. Analizamos entre otros: filiación, movilidad, R.N.M., tiempo quirúrgico y escala Lysholm. Analizamos diferencias estadísticas entre el abordaje femoral desde el portal anteromedial o desde el túnel tibial, mediante los test t de Student, U de Mann Whitney y Chi Cuadrado, con S.P.S.S. 20.0. Resultados: Edad media de 36.5 ± 8.7 años, Lachmann previo en el 96.8% y Pívot Shift previo positivo en el 51.4%, lesiones meniscales asociadas en el 73.8%. Tiempo quirúrgico: 87.1± 18.9 minutos, Lachmann postquirúrgico en el 17.4% y Pívot Shift negativo en el 98.9%. Flexión final de 128.1 ± 5.2°, 95.8 ± 7 puntos de escala final de Lysholm. Complicaciones en el 11%. Altas por mejoría en el 98.9%. No hallamos diferencias significativas entre ambas formas de realización del túnel femoral. Sólo con respecto al tiempo quirúrgico, p=0.004, siendo éste algo mayor cuando se realizada desde el portal anteromedial. Conclusiones: En nuestra experiencia, la ligamentoplastia con el sistema Aperfix® mejora la escala Lysholm, con escasas complicaciones y buen resultado funcional. No hallamos grandes diferencias en cuanto a la realización del túnel femoral, sólo un mayor tiempo quirúrgico cuando se realiza desde el portal anteromedical.

Introduction: reconstruction of the anterior cruciate ligament (A.C.L.) with hamstring grafts would resist 1216 N, with an extensor loss of only 3%. Our goal is to review our experience with this procedure with the Aper x® system. Material and methods: Observational, descriptive and retrospective study. Sample size of 224 cases, minimum followup of 12 months. We analyzed among others: liation, mobility, M.R.I., surgical time and Lysholm’s scale. We analyzed statistical differences between femoral approach from anteromedial portal or from tibial tunnel, using the Student t, Mann Whitney U and Chi Square tests, with S.P.S.S. 20.0. Results: Mean age was 36.5 ± 8.7 years, Lachmann’s test previous surgery was positive in 96.8% and Pivot Shift in 51.4%. There were associated meniscal injuries in 73.8%. Surgical time was 87.1 ± 18.9 minutes. Post-surgical Lachmann’s test was positive at 17.4% and post-surgical Pivot Shift was negative at 98.9%. Final exion was 128.1 ± 5.2°, with 95.8 ± 7 points at Lysholm’s scale. There were complications in 11%. 98.9% of patients returned to their previous jobs. We did not nd signi cant differences between both forms of femoral tunneling. Only with respect to surgical time, p = 0.004, it was longer for cases operated by means of anteromedial portal. Conclusions: In our experience, ligamentoplasty with the Aper x® system improves Lysholm’s scale, with a few complications and good functional outcome. We do not nd great differences in performance of femoral tunnel, only a longer surgical time when it was performed from the anteromedial portal.

Tratamiento coadyuvante a la reparación artroscópica del manguito rotador con plasma rico en plaquetas / Coadjutant treatment for arthroscopic repair of a rotator cuff with plasma rich in platelets

Objetivos: Tras una acromioplastia aumenta a nivel subacromial T.G.F.-beta1 (p = 0.0001), P.D.G.F.-AB (p = 0.02) y bF.G.F. (p < 0.0001). La aplicación de plasma rico en plaquetas (P.R.P.) aportaría en mayor cuantía estos factores. Nuestro objetivo es comparar clínicamente, ecográficamente y biomecánicamente un grupo de 10 pacientes tratado con P.R.P., frente a otros 10 pacientes sin P.R.P., intervenidos con igual técnica artroscópica. Material y método: Estudio prospectivo, aleatorizado, evidencia I. Analizamos variables de filiación, clínicas, operatorias, tests Constant, D.A.S.H. (Disability Arm Shoulder Hand), análisis ecográfico y biomecánico. Seguimiento mínimo: 9 meses. Resultados: El tiempo rehabilitando con P.R.P. fue 5.7 ± 1.1 meses, frente a 7.5 ± 2.7 meses, sin P.R.P. Hubo diferencias ecográficas (3 meses) favorables para el PRP en grosor tendinoso (p=0.05), menor anchura y longitud de la zona desnuda humeral (p=0.02 y p=0.02). Hubo diferencias (9 meses), a favor del grupo con PRP en tests Constant (p=0.05), E.V.A. (Escala Visual Analógica) (p=0.04) y D.A.S.H. (p=0.04). No hubo diferencias biomecánicas, (9 meses), salvo en extensión y flexión (90º y 70º), mejores cuando se aplicaba PRP. Conclusiones: La aplicación de P.R.P. en la cirugía artroscópica de las roturas del manguito rotador, en nuestra experiencia, estaría indicada, ya que mejoraría los tests de Constant, E.V.A. y D.A.S.H., a los 9 meses de la cirugía. Mejoraría el grosor tendinoso, y disminuiría la anchura y longitud de la zona “calva” humeral, a los 3 meses. Mejoraría biomecánicamente la flexoextensión. Sin afectar al tiempo quirúrgico, reduciría la rehabilitación, la tasa de reintervenciones, con mejor satisfacción (AU)

Objectives: After acromioplasty, subacromial levels for TGF-beta1 (p = 0.0001), PDGF-AB (p = 0.02) and bFGF (p< 0.0001) increased. The application of plasma rich in platelets (PRP) would contribute greatly to these factors. Ourobjective is to clinically, ultrasonographically and bio-mechanically compare a group of 10 patients, treated with PRP, in comparison with another 10 patients without PRP undergoing the same arthroscopic technique Material and method: Prospective, randomized and evidence based study, in which we analyzed a number of variables,including background, clinical data, surgical data, Constant tests, DASH (Disability Arm Shoulder Hand), ultrasound and biomechanical analysis. Minimum follow-up: 9 months. Results: the rehabilitation time with PRP was 5.7 ± 1.1 months, in comparison with 7.5 ± 2.7 months without PRP. There were ultrasound differences (3 months) favorable for PRP in thickness (p=0.05), lesser width and length in the bare humeral zone (p=0.02 and p=0.02). There were differences (9 months) in favor of the PRP group in the Constant tests (p=0.05), CVAS (Cosmetic Visual Analogue Scale) (p=0.04) and DASH (p=0.04). There were no bio-mechanical differences (9 months), except in extension and flexion (90º and 70º), with improvements with the application of PRP. Conclusions: The application of PRP in surgical arthroscopy of the rotator cuff, in our experience, would be indicated, as it improves most of the Constant tests, CVAS and DASH 9 months after surgery. It improves tendineus thickness while decreasing the width and length of the bare humeral area after 3 months. It bio-mechanically improves flexion-extension. Without affecting the surgical time, it reduces rehabilitation, the re-intervention rate and offers improved satisfaction (AU)

Arthroscopic arthrodesis of the shoulder: Fourteen-year follow-up.

Shoulder arthrodesis is indicated in infections, brachial paralysis, irreparable rotator cuff tears, osteoarthritis without indication of prosthesis, rescue after arthroplasty, or after surgery for cancer. Arthroscopic arthrodesis is exceptional. Our aim is presenting our result after 14 years of follow-up of one patient. We present a case report of a 17-year-old male patient. He suffered fracture of left scapula (type V, Ideberg), fracture of left clavicle (type I, Craig), and fracture of left distal ulna. We realized osteosynthesis of clavicle (plate and screws) with the aim of treating this floating shoulder. Electromyography showed partial axonotmesis of axilar nerve. After 7 months of follow-up, axonotmesis was still present. We realized arthroscopic shoulder arthrodesis (three cannulated screws). Fourteen years later, shoulder movement was as follows: Flexion, 0-90°; maximum abduction, 40° with shoulder atrophy; Constant, 47 points; and UCLA, 17 points, without pain. Arthrodesis with screws reaches a subjective benefit in 82% of patients. Percentage of pseudarthrosis is less than in patients treated with plates, although the risks of infections, fractures, and material removal are greater than in patients treated with plates. Shoulder arthroscopic arthrodesis is exceptional, but it allows minimal surgical aggression.
