Anteroposterior (AP) X-ray of the proximal femur demonstrating internal fixation of an intertrochanteric fracture using a short cephalomedullary nail. The radiographic study shows a titanium alloy intramedullary nail positioned within the femoral shaft, secured proximally by two parallel cephalic lag screws extending into the femoral head to stabilize the fracture site. A single distal locking screw is visible at the inferior end of the nail to prevent rotation and axial displacement. The image displays acceptable closed reduction with evidence of radiographic healing, characterized by the continuity of the cortical bone and callus formation across the fracture line at the 4-month postoperative stage. Anatomical landmarks including the acetabulum, femoral head, and greater trochanter are clearly visible, illustrating the proper alignment and tip-apex distance of the orthopedic hardware for hip fracture management.

Anteroposterior (AP) X-ray of the proximal femur demonstrating an intramedullary nail fixation for an intertrochanteric fracture. The diagnostic image shows a cephalomedullary nail positioned within the femoral canal, secured by a proximal helical blade extending into the femoral head and a distal transverse locking screw. Annotated green lines indicate the Neck-Shaft Angle (NSA), measuring the alignment between the femoral shaft and neck axes. Specific geometric measurements are labeled for post-operative monitoring: Line A measures the distance from the helical blade's distal end to the nail's lateral cortex to monitor blade backout; Line B (yellow) measures distance to the medial cortex to assess femoral neck shortening or cut-through; and Line C (blue) measures distance to the superior cortex to evaluate for superior cutout. This radiograph illustrates key orthopedic parameters used to evaluate the mechanical stability and potential complications of proximal femoral internal fixation during clinical follow-up.

This anteroposterior (AP) x-ray radiography shows the surgical fixation of an intertrochanteric femoral fracture using a long cephalomedullary nail. The orthopedic construct consists of a radiopaque intramedullary nail inserted into the femoral shaft, with a thick cephalic lag screw and a secondary integrated stabilization pin (anti-rotation pin) extending proximally through the femoral neck and into the femoral head. The imaging demonstrates the fracture site located between the greater and lesser trochanters, showing signs of surgical reduction and stabilization. The cortical margins of the proximal femur appear irregular and disrupted consistent with a high-energy or unstable fracture pattern (OTA/AO type 31). This diagnostic image illustrates the standard of care for stabilizing extracapsular hip fractures to facilitate weight-bearing and bone union while preventing collapse or varus deformity. Relevant for orthopedic trauma education, specifically in understanding intramedullary fixation mechanics and proximal femoral anatomy.
