Abstract
Purpose

To analyze the functional and radiological results as well as the complications of carpal scaphoid fractures treated by means of volar percutaneous fixation.

Materials and Methods

A retrospective study was carried out of 41 patients with a mean follow-up of 15 months (range: 12-54). Fractures included in the study correspond to those classified as types B1 and B2 on Herbert's scale further to a detailed radiographic study for the carpal scaphoid. Fractures of the tubercle and the proximal pole were excluded from the study. Demographic data were collected on the mechanism of injury, postoperative complications and any associated lesions. Clinical and radiological evaluations were performed. The adapted DASH questionnaire was used for the functional assessment.

Results

Fracture healing occurred at 7-and-a-half weeks. All patients started using their hand in the first 2 weeks. Mean wrist range of motion one year into follow-up was 70° of extension and 65° of flexion. The final score on the adapted DASH scale was 44 points when there were no associated lesions and 80 when the fracture was associated with other injuries. The complications rate was 5.8% intraoperatively (2 instances of guide wire breakage) and 5.8% during follow-up. All cases went on to heal, except for one which developed pseudoarthrosis. OR time was of 20 min on average.

Conclusions

Volar percutaneous fixation is a simple, rapid technique characterized by low morbidity rates and scarce significant complications, which accelerates the patients’ functional recovery.

Resumen
Objetivo

Analizar los resultados funcionales y radiológicos, así como las complicaciones de las fracturas del escafoides carpiano tratadas mediante la técnica de osteosíntesis percutánea volar.

Material y métodos

Se realizó un estudio retrospectivo de 41 pacientes con un seguimiento medio de 15 meses (12 a 54). Las fracturas incluidas correspondían a los tipos B1 y B2 de la clasificación de Herbert, tras el estudio radiográfico específico para el escafoides carpiano. Se excluyeron del estudio las fracturas del tubérculo y del polo proximal. Se recogieron datos demográficos y sobre el mecanismo causal, complicaciones postoperatorias y lesiones asociadas. Se realizaron evaluaciones clínicas y radiográficas. En la evaluación funcional se utilizó el DASH adaptado.

Resultados

La consolidación de la fractura se evidenció en una media de 7 semanas. Todos los pacientes comenzaron a utilizar la mano en las 2 primeras semanas. La movilidad media de la muñeca al año de seguimiento fue de 70° de extensión y de 65° de flexión. La puntuación final según la escala DASH adaptada fue de 44 puntos cuando no hubo lesiones asociadas y de 80 cuando la fractura se asociaba a otras lesiones. Hubo un 5,8% de complicaciones intraoperatorias (2 casos de rotura de aguja guía) y un 5,8% durante el seguimiento. Todos los casos consolidaron, salvo uno que evolucionó a seudoartrosis. La media del tiempo quirúrgico empleado fue de 20 min.

Conclusiones

La osteosíntesis percutánea por vía volar es una técnica sencilla, rápida, con mínima morbilidad, escasas complicaciones importantes y que acelera la recuperación funcional del paciente.
