Social and economic benefits of flexible intramedullary nails in the treatment of pediatric femoral shaft fractures.

All patients between the ages of 5 and 15 years with isolated femoral shaft fractures treated at our institution with flexible intramedullary nails between 1996 and 1998 were examined and compared to an age-matched group of patients treated with spica casting. All fractures healed well with no significant complications. Patients treated with flexible intramedullary nails achieved earlier independent ambulation, at an average of 19 days, compared to 106 in the control group (P<.0001). They also attained earlier independent bathroom use (21 versus 79 days, P<.0001). Hospital stays were significantly shorter as well (6 versus 29 days, P<.0001). These patients also returned to school earlier, at 28 days postinjury, compared to 120 days for patients in spica casts (P<.0001). The use of flexible intramedullaty nails allowed patients and their families to achieve independence months earlier than the spica cast patients. Earlier return to school, independent ambulation, and independent bathroom use are advantages of this treatment modality.
