The surgical approach for humeral implant failure can be challenging due to neurovascular anatomy and the possible necessity of osteosynthesis removal. We present a rare case of humeral nail bending after secondary trauma in a patient with preexistent nonunion of the humerus after intramedullary nailing. During revision surgery, the nail was sawed in half and the distal part was removed, followed by plate osteosynthesis with cable fixation to achieve absolute stability. The patient regained a full range of motion 1 year after surgery, and complete healing of the fracture was seen on imaging.

Introduction: Subtalar joint arthrodesis is primarily indicated for advanced osteoarthritis, hindfoot deformity, and/or instability. During the first 6-10 weeks after surgery, there is an intermediary structurally weaker state before complete bony fusion of the calcaneus and talus occurs. Loading of the foot can lead to mechanical stresses and relative movements in the former joint gap, which can impede the fusion process.

Objective: Osteosynthesis in dislocated diametaphyseal forearm fractures is intended to restore anatomy and function. Antegrade intramedullary nailing in the radius is used to restore length, rotation, and axis within the age-specific correction limits. Sufficient stability ensures early functional postoperative treatment without load.

Distraction osteogenesis (DO) is a bone regenerative maneuver, which is conventionally done with external fixators and, more recently, with telescopic intramedullary nails. Despite the proven effectiveness, external approaches are intrusive to the patient's life while intramedullary nailing damages the growth plates, making them unsuitable for pediatric patients. An internal DO plate fixator (IDOPF) was developed for pediatric patients to address these limitations.

This study focuses on evaluating the failure resistance of a previously reduced tibia with internal fixation implants as PLate (PL) or InterMedullary Nail (IMN), subjected later to a tibial lateral trauma. To replicate this type of trauma, which can be caused by a road accident, a three-point bending test is considered using experimental tests and numerical simulations. The withstand evaluation of the tibia-PL and tibia-IMN structures was conducted by following the load transfer through, the bone and the used implants.

Objective: Closed manipulation and percutaneous pinning is standard of care for displaced supracondylar humerus fractures, yet the optimal pin configuration, particularly in the sagittal plane, is not well defined. This study evaluates how sagittal plane pin variations affect construct strength biomechanically.
Methods: One hundred synthetic pediatric humerus models were used to emulate supracondylar humerus fracture.
