Reducción cerrada y fijación intramedular de fracturas del cuello del quinto metacarpiano: técnica retrógrada vs. anterógrada. Estudio prospectivo / Closed reduction and intramedullary fixation of fifth metacarpal neck fractures: Retrograde vs. anterograde technique. Prospective study

Introducción: La fractura de quinto metacarpiano es una dolencia muy frecuente que puede ocasionar deformidad y afectación funcional para la prensión adecuada de la mano. La reinserción a las actividades cotidianas o laborales se relaciona con el tratamiento recibido y la rehabilitación. En fracturas de cuello de quinto metacarpiano la fijación interna con aguja Kirschner es un método de tratamiento convencional con variantes que afectan su desenlace. Objetivo: Comparar los resultados funcionales y clínicos del tratamiento de las fracturas de quinto metacarpiano con el uso de agujas Kirschner vía retrógrada versus anterógrada. Material y métodos: Estudio comparativo, longitudinal, prospectivo, realizado en un hospital de tercer nivel de Traumatología, en pacientes con fractura de cuello de quinto metacarpiano, con seguimiento clínico, radiográfico y con escala Quick DASH a la tercera, sexta y octava semana postoperatoria. Resultados: Se incluyeron 60 pacientes (58 hombres, 2 mujeres), con un promedio de edad de 29,63±10,15 años, con fractura de quinto metacarpiano, tratados mediante reducción cerrada y estabilización con aguja Kirschner. La vía anterógrada mostró un rango de flexión metacarpofalángica a las 8 semanas de 89,11 grados (p<0,001; IC95% [−26.81; −11,42]), un valor de la escala DASH de 18,17 (p<0,001; IC95% [23,45; 39,12]) y un promedio de 27,35 días de incapacidad laboral (p=0,002; IC95% [16,22; 62,14]), comparada con la vía retrógrada. Conclusión: La estabilización con aguja Kirschner vía anterógrada mostró superioridad en resultados funcionales y en amplitud de movimiento metacarpofalángica comparados con los operados por vía retrógrada a la octava semana del postoperatorio.(AU)

Introduction: The fifth metacarpal fracture is a frequent pathology that can cause deformity and functional impairment for the adequate grip of the hand. Reintegration into daily or working activities is related to the treatment received and rehabilitation. In fractures of the neck of the fifth metacarpal, internal fixation with a Kirschner's wire is a conventional treatment method with variants that affect its outcome. Aim of the study: To compare the functional and clinical results of the treatment of fifth metacarpal fracture with the use of retrograde versus antegrade Kirschner wires. Material and methods: Comparative, longitudinal, prospective study at a third-level trauma center in patients with a fifth metacarpal neck fracture, with clinical, radiographic and Quick DASH scale follow-up at the 3rd, 6th, and 8th postoperative week. Results: Sixty patients were included (58 men, 2 women), age of 29.63±10.15 years, with a fifth metacarpal fracture, treated by closed reduction and stabilization with a Kirschner wire. The antegrade approach showed a metacarpophalangeal flexion range at 8 weeks of 89.11° (p<0.001; 95% CI [−26.81; −11.42]), a DASH scale value of 18.17 (p<0.001; 95% CI [23.45; 39.12]), and an average of 27.35 days to return to work (p=0.002; 95% CI [16.22; 62.14]), compared with the retrograde approach. Conclusion: Stabilization with antegrade Kirschner wire showed superior functional results, and metacarpophalangeal range of motion, compared to those operated via retrograde approach.(AU)
