Artrodesis de las cuatro esquinas del carpo con placa y tornillos / Carpal four corner arthrodesis with plate and screws

Introducción y objetivos: La artrodesis de las cuatro esquinas (grande, ganchoso, semilunar y piramidal) suprime el movimiento de la articulación mediocarpiana (30% del total del movimiento de la muñeca) y permite movimiento sin dolor en la articulación radiocarpiana (63-70%). Nuestro objetivo es revisar nuestra experiencia con esta técnica realizada con placa y tornillos. Material y métodos: Estudio observacional, descriptivo y retrospectivo, sobre 11 pacientes, en 6 años, seguimiento medio de 29.4 ± 8 meses. Las variables analizadas fueron filiación, lesiones asociadas, intervenciones previas, aspectos quirúrgicos, complicaciones, entre otras. La edad media fue de 41.6 ± 5.8 años. Todos los pacientes fueron varones. El 72.7% de las manos fueron derechas. La muñeca dominante fue la afectada en el 72.7%. Hubo una fractura previa escafoidea en 3 casos, inestabilidad escafolunar en 7 casos e inestabilidad lunotriquetal en 1 caso. El tiempo quirúrgico empleado fue de 92.2 ± 24.7 minutos. Resultados: La consolidación sucedió en unas 10.6 ± 1.6 semanas. Hubo hasta un 36.4% de reintervenciones, para retirar placa y realizar artrodesis total de muñeca. Los resultados clínicos fueron: Mayo Wrist Score: 53.6 ± 28.4 puntos y E.V.A. final: 2.86 ± 2 puntos. Hallamos más complicaciones en aquellos pacientes que habían presentado lesiones previas escafolunares, p=0.01 (Chi Cuadrado). Se observó pseudoartrosis en el 11.1%. Los arcos de movimiento finales fueron: Flexoextensión final de 58.2 ± 11º, desviación radial de 11.1 ± 1º y desviación cubital de 20.7 ± 1.7º. Discusión: En nuestra experiencia, la artrodesis de las cuatro esquinas del carpo con placa y tornillos, es una técnica útil, en el tratamiento de las secuelas fundamentalmente tras inestabilidad escafolunar, aunque con riesgo de otras complicaciones, que han llevado en esta serie a reintervenir a la tercera parte de los casos, para retirarla y realizar artrodesis total de muñeca

Introduction and objetives: Four corner arthrodesis (capitate, hamate, lunate and triquetrum) suppresses the movement of midcarpal joint (30% of the total movement of the wrist) and allows movement without radiocarpal joint pain (63-70%). Our goal is to review our experience with this technique performed with plate and screws. Material and methods: It was an observational, descriptive and retrospective study on 11 patients, in 6 years. Follow up was about 29.4 ± 8 months. We analyzed some variables: affiliation, associated injuries, previous surgeries, surgical aspects, complications, among others. The average age was 41.6 ± 5.8 years. 72.7% of wrists were right. Dominant wrist was affected on 72.7% of patients. We appreciated previously a scaphoid fracture in 3 cases, scapholunate instability in 7 cases and lunotriquetal instability in 1 case. Surgery time was about 92.2 ± 24.7 minutes. Results: Fusion was reached in 10.6 ± 1.6 weeks. 36.4% of patients required plate removal and perform complete wrist arthrodesis. Clinical results were: Mayo Wrist Score: 53.6 ± 28.4 points and V.A.S.: 2.86 ± 2 points. We found more complications in those patients who had previous scapholunate injuries p =0.01 (Chi Square). Pseudoarthrosis was observed in 11.1%. Final movement arcs were: flexoextension 58.2 ± 11º, radial deviation 11.1 ± 1º and ulnar deviation of 20.7 ± 1.7º. Discussion: In our experience, carpal four corner arthrodesis with plates and screws is an useful technique in treating consequences of scapholunate instability. However, it exists other complications, which have led to reoperate in this serie the third of cases, in order to remove and make full arthrodesis of the wrist

Transferencias del extensor indicis proprius en casos de roturas del extensor pollicis longus / Extensor indicis proprius transferences in cases of extensor pollicis longus ruptures

Introducción y objetivos: La sutura directa en los casos de rotura del extensor pollicis longus (EPL) puede llevar asociado el fallo de la misma. Por ello, la transferencia tendinosa del extensor indicis proprius (EPI) es una buena alternativa. Nuestro objetivo es describir nuestra experiencia con esta técnica. Material y métodos: Estudio observacional descriptivo y retrospectivo sobre 29 casos. Variables: Edad, sexo, mano dominante, actividad laboral, tiempo quirúrgico. Análisis de resultados obtenidos en test de Geldmacher, SEEM y EVA. Resultados: Edad media de 48.04 ± 9.4 años. 72.4% varones, 27.6% mujeres. Brazo dominante en el 55.2%. 3.4% diabéticos y 6.9% con tratamiento corticoideo. Traumatismo directo en el 58.6%. Diagnóstico ecográfico en el 89.7%. Tiempo quirúrgico: 51.8 ± 12.5 minutos. Escala Geldmacher: 15.79 ± 5.8 puntos. Escala SEEM: 70.36 ± 20.4 puntos. Rotura de plastia en 13.8%. Altas por mejoría en 96.6%. Conclusiones: Las roturas de este tendón se asocian a fracturas de radio distal, tratamiento con corticoides, artritis reumatoide o tras osteosíntesis de fracturas de radio con placas volares. En nuestra experiencia, en los casos de rotura del EPL, consideramos que la trasposición del EPI es una alternativa eficaz, con un reducido número de complicaciones

Introduction and objectives: Direct suture in cases of rupture of extensor pollicis longus (EPL) tendon has been associated to suture tear. For this reason, tendon transfer of extensor indicis proprius (EPI) tendon is a good alternative. Our objective is describe our experience with this technique. Matherial and methods: Observational descriptive and retrospective study about 29 cases. Variables: Age, sex, dominant hand, laboral activity, time of surgery. We analize results with Geldmacher’ scale, SEEM and VAS scores. Results: Average age was 48.04 ± 9.4 years. 72.4% were males and 27.6% were females. Dominant arm was affected in 55.2% of cases. 3.4% were diabetics and 6.9% received corticoid treatment. Direct trauma appeared in 58.6% of cases. Sonographic diagnosis was in 89.7% of cases. Surgical time was of 51.8 ± 12.5 minutes. Geldmacher’ scale: 15.79 ± 5.8 points. SEEM score: 70.36 ± 20.4 points. Plastia rupture happened in 13.8% of patients. 96.6% of patients returned to their work. Conclusions: Ruptures of this tendon have been associated with distal radius fractures, corticoid treatment, rheumathoid arthritis or after osteosynthesis with volar plates in radius fractures. In our experience, in cases of rupture of EPL, we consider that transposition of EIP it is an effective alternative, with minimal number of complications

Introducción y objetivo. Las lesiones del fibrocartílago triangular (FCT) están asociadas en muchas ocasiones con inestabilidad de la articulación radiocubital distal. El tratamiento artroscópico de estas lesiones mejora el pronóstico funcional de los pacientes afectados. El objetivo del presente trabajo es evaluar los resultados funcionales y laborales de la reparación artroscópica con anclaje óseo sin nudo de lesiones del FCT asociadas a fracturas de extremidad distal del radio. Material y método. Estudio observacional, descriptivo entre noviembre de 2011 y enero de 2014 de 21 pacientes con fractura de radio distal asociada a lesiones tipo IB de Palmer (clases 2 y 3 de Atzei) del FCT tratados mediante reparación artroscópica con anclaje óseo sin nudo (PopLok® 2,8 mm, ConMed, EE. UU.). El tiempo medio de seguimiento fue de 18 meses. Analizamos los resultados funcionales (Mayo Wrist Score) y laborales. La edad media fue de 43,0 ± 8,8 años, con un 19% de mujeres. Se hallaron 5 casos con lesión escafolunar asociada. Resultados. La media obtenida en la escala funcional de Mayo Wrist Score fue de 83,4 ± 16,1 puntos. El tiempo de baja medio fue de 153,16 ± 48,5 días. La recuperación laboral sin limitaciones fue posible en el 89,5% de los casos. No se recogieron complicaciones postoperatorias. Conclusiones. La reparación artroscópica con anclaje óseo sin nudo de lesiones IB del FCT en pacientes con fractura de radio distal supone un método de tratamiento mínimamente invasivo, que mejora la tensión en la reparación y evita el posterior destensado, en nuestra experiencia, con baja tasa de complicaciones y buenos resultados funcionales y laborales (AU)

Introduction and objective. Lesions of triangular fibrocartilage (TFC) are associated with distal radioulnar joint instability. Arthroscopic treatment of these lesions improves functional outcome of affected patients. The aim of the present work is to evaluate functional and occupational outcome of TCF repair using an arthroscopic knotless anchor device in patients with associated distal radius fracture. Material and methods. An observational, descriptive study was carried out between November 2011 and January 2014 including 21 patients with distal radius fracture and Palmer 1 B lesions of TCF (Atzei class 2 and 3) that were treated by arthroscopic knotless anchor (PopLok® 2,8 mm, ConMed, USA). Mean follow-up was 18 months. Functional (Mayo Wrist Score) and occupational outcome results were analyzed. Mean age of the group was 43.0 ± 8.8 years, with 19% of the patients being female. There was an associated scapholunate lesion in 5 cases. Results. Functional results reached a mean of 83.4 ± 16.1 points onMayo Wrist Score. Mean sick-leave time was 153.16 ± 48.5 days. Complete occupational reintegration was reached in 89.5% of cases. There were no postoperative complications. Conclusions. Arthroscopic knotless anchor repair of 1 B TFC tears is a minimally invasive method of treatment that improves tension of fixation, avoiding subsequent loosen, in our experience, with few complications and good functional and occupational results (AU)
