- Outcomes:
- in the report by Larson CM, et al (2002), 15 patients (mean age, 21.7 years) underwent cannulated screw fixation of a Jones fracture;
- there were six treatment failures: four refractures and two symptomatic nonunions;
- mean time to full activity was 6.8 weeks for the patients with failure compared with 9 weeks for patients who did not have complications;
- although all patients were asymptomatic and radiographically progressing to union before return to full activity, only one of six patients with failures had complete radiographic union, compared with six of seven patients with no complications;
- there was a
higher proportion of elite athletes (division I or professional level) among the failure group (83%) compared with those without complications (11%);
- return to full activity, especially among elite athletes, before complete radiographic union was predictive of failure
