Salvage Hind-Foot Fusion Using a Tibiotalocalcaneal Intramedullary Nail
1. Tibiotalocalcaneal Intramedullary Nail The Tibiotalocalcaneal (TTC) Intramedullary Nail is a specially designed fixation device intended for use in complex hind-foot fusion procedures involving the ankle (tibiotalar) and subtalar joints. This retrograde nail is inserted through the calcaneus (heel bone), travels through the talus, and extends into the tibia. It incorporates locking screw options both […]

Adolescent Lateral Entry Femoral Nail (ALFN) vs Elastic Stable Intramedullary Nailing (ESIN) in Pediatric Diaphyseal Femur Fractures
Introduction Pediatric diaphyseal femur fractures are among the most common long bone injuries in children and adolescents. With modern orthopedic implants, two main fixation systems are used: the Elastic Stable Intramedullary Nailing (ESIN) and the Adolescent Lateral Entry Femoral Nail (ALFN). Understanding their indications and biomechanical differences is essential for achieving optimal healing and functional recovery. […]

Z-effect and Reverse Z-effect after Intramedullary Nails for Trochanteric Femur Fractures
The purpose of intramedullary nails with two lag screws was to increase bone purchase and rotational control inside the femoral head, preventing cutoff and eventual fixation failure. In comparison to an intramedullary nail with a single lag screw, a two lag screw design offers comparable rigidity and stability and has a noticeably higher failure strength. […]
