Abstract
Objectives

We studied the use of vascularized bone graft (VBG) in combination with a fixation with screw in patients with scaphoid nonunion and avascular proximal poles.

Materials and methods

Between January 2006 and December 2009, we treated 10 patients with scaphoid nonunion with avascular proximal poles. There were 10 males with nonunion. Their average age was 27 years (range: 18–46 years). The average followup was 18 months (range: 12–43 months). The clinical valuation was the scale of pain (VAS), the range of motion and grip strength. The radiological valuation included radiographies, CT and MRI. We studied the scapholunate angle, the Carpal Height Index by Nattrass et al. and the Mayo Wrist Score.

Results

The mean preoperative VAS was 4.5 (2–8) and postoperative VAS 1 (0–2). All patients achieved union in an average time of 15 weeks (range: 6–25 weeks). X-rays and CT showed a complete osseous union in all patients. Carpal Height Index was a mean of 1.50 preoperative and 1.58 postoperative. The scapholunate angle was a mean of 52° preoperative and 49° postoperative. Mayo Wrist Score was 53 preoperative and 92 postoperative.

Conclusions

We have found that the technique which combines VBG with mini acutrak® screw, is successful in treating scaphoid nonunions with avascular poles. We prefer to use the vessel 1, 2 ICSRA. If this vessel is occasionally absent, other pedicles may be used.

Resumen
Objetivo

Evaluar los resultados del injerto óseo vascularizado (IOV) de la arteria 1, 2 suprarretinacular intercompartimental (1,2 SRIC) junto con la fijación, en pseudoartrosis de escafoides y necrosis del polo proximal.

Material y método

Realizamos un estudio retrospectivo, entre enero de 2006 y diciembre de 2009. Se trata de 10 pacientes con pseudoartrosis de escafoides con necrosis del polo proximal. Todos eran varones con edad media de 27 años (rango: 18–46). El seguimiento medio fue de 18 meses (rango: 12–43). La evaluación clínica incluye el dolor según la escala visual analógica (EVA), el balance articular y la fuerza de prensión. La evaluación radiológica incluye radiografías, TC y RNM. Se midió el ángulo escafolunar y la altura carpiana de acuerdo con el índice de Nattrass et al. La escala utilizada fue la Mayo Wrist Score.

Resultados

La consolidación tuvo lugar en todos en un tiempo medio de 15 semanas (rango: 6–25 semanas). La media de EVA preoperatoria fue de 4,5 (2–8) y postoperatoria de 1 (0–2). El índice de la altura carpiana de Nattrass preoperatorio fue de 1,50 y postoperatorio de 1,58. El ángulo escafolunar medio preoperatorio fue de 52° y postoperatorio de 49°. Los valores preoperatorios de la Mayo Wrist Score fueron de 53 y los valores postoperatorios de 92.

Conclusiones

La técnica que combina el IOV y la fijación con un tornillo mini-acutrak® presenta buenos resultados, en el tratamiento de las pseudoartrosis de escafoides con necrosis del polo proximal. Preferimos el uso de la arteria 1,2 SRIC. En el caso de que esta arteria esté ausente se pueden utilizar otros pedículos vasculares.
