An intramedullary nail includes a shaft between a proximal end and a distal end. The distal end includes a first bend that extends from an anterior side of the intramedullary nail toward a posterior side and a second bend that extends from the posterior side toward the anterior side of the intramedullary nail. The two bends transfer an insertion force on a distal end of the intramedullary nail to, and along a longitudinal axis of the shaft of the intramedullary nail.

Bone fixation devices, systems, and methods

A femur fixation system includes an intramedullary nail that includes a first bending stiffness and a bone plate that includes a second bending stiffness and a second torsional stiffness. In the femur fixation system either at least one of the second torsional stiffness compensates for the first torsional stiffness and the first torsional stiffness is insufficient to enable the intramedullary nail to stabilize the bone fracture independently of the bone plate or the first bending stiffness compensates for the second bending stiffness and the second bending stiffness is insufficient to enable the bone plate to stabilize the bone fracture independently of the intramedullary nail.

A system for monitoring and controlling negative pressure wound therapy includes a microcontroller that controls means for maintaining reduced air pressure based on a pressure signal from a pressure sensor. The means for maintaining reduced air pressure may include a vacuum pump and valve. The system includes a mobile communication device having a microprocessor, touchscreen display, data storage device, GPS module, and wireless transceiver. The microprocessor generates control signals sent to the microcontroller to control the means for maintaining reduced air pressure to provide continuous or intermittent reduced air pressure. The microprocessor monitors the pressure signal and generates a closed-system alarm, leak-detected alarm or open-system alarm. The closed-system alarm indicates an air pressure leak rate below a closed-system threshold. The leak-detected alarm indicates an air pressure leak rate above a leak-detected threshold and below an open-system threshold. The open-system alarm indicates an air pressure leak rate above the open-system threshold.

An implant system includes a pair of fasteners, a plate, and a horseshoe-shaped clip member. The clip member is located within a recess of the plate and is shaped so as to cooperate with the recess so that lobes of the clip block installed fasteners from backing out, yet, the lobes may be purposefully be deflected to enable removal of fasteners if desired.
