Study limitations
intramedullary nailing [The primary limitation, malunion
Overall, this is a relatively favorable group, as they have little displacement with no need for reduction and, with that, they have little risk of malunion and rotation limitation. This contrasts with dislocated cases that often re-dislocate causing malunion or rotation problems, resulting in more intramedullary nailing [The primary limitation was the inevitable non-blinding of the clinical assessment. Again, at long-term follow-up the initial cast morphology revealed which group the patients were in. However, radiological assessments again were blinded.Second, this study was conducted with a small sample size of only 38 patients of the 47 primarily included patients. But with a follow-up percentage of 70%, in this young population with a relatively long follow-up period, this is a good response. Furthermore, a previous study showed that when cases are missing at random or completely at random, up to 60% loss to follow-up is acceptable, without influencing the outcome [
