Background: Debate exists over the safety of rigid intramedullary nailing of femoral shaft fractures in skeletally immature patients. The goal of this study was to describe functional outcomes and complication rates of rigid intramedullary nailing in pediatric patients.
Methods: A retrospective review was performed of femoral shaft fractures in skeletally immature patients treated with trochanteric rigid intramedullary nailing from 1987 to 2009. Radiographs made at initial injury, immediately postoperatively, and at the latest follow-up were reviewed. Patients were administered the Nonarthritic Hip Score and a survey.
Results: The study population of 241 patients with 246 fractures was primarily male (75%) with a mean age of 12.9 years (range, eight to seventeen years). The majority of fractures were closed (92%) and associated injuries were common (45%). The mean operative time was 119 minutes, and the mean estimated blood loss was 202 mL. The mean clinical follow-up time was 16.2 months (range, three to seventy-nine months), and there were ninety-three patients with a minimum two-year clinical and radiographic follow-up. An increase of articulotrochanteric distance of >5 mm was noted in 15.1% (fourteen of ninety-three patients) at a minimum two-year follow-up; however, clinically relevant growth disturbance was only observed in two patients (2.2%) with the development of asymptomatic coxa valga. There was no femoral head osteonecrosis. Among the 246 fractures, twenty-four complications (9.8%) occurred. At the time of the latest follow-up, 1.7% (four of 241 patients) reported pain. The average Nonarthritic Hip Score was 92.4 points (range, 51 to 100 points), and 100% of patients reported satisfaction with their treatment.
Conclusions: Rigid intramedullary nailing is an effective technique for treatment of femoral shaft fractures in pediatric patients with an acceptable rate of complications.

Bone healing is a complex, dynamic process involving a series of well-coordinated stages, influenced by both mechanical and biological factors. The skeletal system, composed of inorganic (36%), organic (36%), and water (28%) components by volume, plays a crucial role in maintaining structural integrity and mineral homeostasis. Bone is classified into two main types based on microstructure: lamellar and woven bone, with lamellar bone being stronger and more durable.

Background: Flexible intramedullary nailing is an effective method of stabilization in pediatric patients with a humeral shaft fracture when surgery is indicated. Although these fractures are most often treated nonoperatively, operative indications include open fractures, bilateral injuries, compartment syndrome, pathologic fractures, neurovascular compromise, unacceptable alignment after attempted nonoperative treatment, and ipsilateral upper-extremity injuries. The current literature on flexible intramedullary nailing of the pediatric humeral shaft lacks concise descriptions of available entry points, which directly affect the subsequent technique, and of pertinent pediatric-specific anatomy.

Article Synopsis
- * A study conducted at a UK pediatric institution reviewed the medical records of 27 patients who underwent this treatment over 11 years, focusing on their preoperative management, surgical indications, and outcomes.
- * Results showed that all fractures healed successfully, though complications like implant issues and one case of nonunion during limb lengthening were noted, highlighting the effectiveness and safety of rigid intramedullary nailing when carefully planned within a multidisciplinary team.

Infected segmental bone defects (ISBD) of the femur and tibia pose a significant challenge. Traditionally, bone fixation in the first stage of the Masquelet technique involves external fixation, but intramedullary nail fixation has recently gained popularity. Despite this, little attention has been focused on the elaboration, implantation, and removal of the spacer around the nail.

Article Synopsis
- Proximal femoral nailing (PFN) is beneficial for treating intertrochanteric fractures but poses higher complication risks, especially in obese patients due to issues like poor technique and incorrect entry points.
- A study compared the outcomes of using an oriented flexible reamer versus a rigid reamer in PFN procedures on patients aged 65 and older, focusing on factors such as reduction quality and complication rates over a year of follow-up.
- Results indicated that patients treated with the flexible reamer had better outcomes, including a more favorable femoral neck-shaft angle, improved reduction quality, and a lower rate of complications compared to those treated with the rigid reamer.
