Introduction Femoral shaft fractures are among the most common long bone fractures in pediatric patients, constituting approximately 1.6% of all pediatric fractures. These fractures result from high-energy trauma, such as road traffic accidents (RTAs) and falls from height, making them a significant concern in pediatric orthopedic trauma. The management of femoral shaft fractures varies according to patient age, fracture pattern, and associated injuries, necessitating a tailored approach for optimal outcomes.  Materials and Methods A prospective study was conducted over a period of 1 year in the Department of Orthopedics, Shadan Institute of Medical Sciences, Teaching Hospital & Research Centre. Patients aged 5–16 years diagnosed with closed femoral shaft fractures and treated with TENS were included. This study evaluates the functional outcome of femoral shaft fractures in pediatric patients treated with TENS, focusing on healing time, complications, weight-bearing status, and overall functional recovery. A prospective study was conducted on pediatric patients aged 5–16 years with closed femoral shaft fractures treated using TENS.  Results The most common fracture type in this dataset is transverse (25 cases), followed by oblique (15 cases) and comminuted (10 cases). This distribution suggests that the majority of fractures in this dataset are relatively stable (transverse and oblique), with a smaller proportion being more complex (comminuted). The fracture heals on average in 8.2 weeks, but full functional recovery (full weight-bearing) takes longer, at 10 weeks. Patients can begin partial weight-bearing at 6 weeks, which is an important milestone in the rehabilitation process. The most common complication in this dataset is nail prominence (6%), followed by limb length discrepancy (4%) and infection (2%). The majority of patients (40 out of 50, or 80%) achieved an excellent outcome. A smaller proportion (8 out of 50, or 16%) had a satisfactory outcome. Only a few patients (2 out of 50, or 4%) had a poor outcome.
