HUMERAL FRACTURE SYSTEM Key Benefits AEQUALIS™ Fixation Philosophy Fix the tuberosities in order to support the head AEQUALIS™ IM Nail Design Tuberosity-based screw pattern lags fragments perpendicular to the pull of the muscles Screw pattern supports periphery of humeral head fragment and avoids the articular surface Straight nail design avoids rotator cuff insertion A new perspective on fracture management Clinical Results • 24 patients treated with a mean age of 64 years (range, 27-83 years) for displaced unstable fractures using the AEQUALIS™ IM Nail • Patient follow-up averaged 9 months (range 6-18 months) • All fractures healed and all patients recovered enough motion to perform daily activities independently • No patient required further surgical intervention Advantages of IM Nailing • Less extensive soft tissue dissection maximizes periosteal blood supply while preserving vital surrounding structures. • Improved construct stability even in the case of comminuted fractures and osteopenic bone while still maintaining desired elasticity. • Fracture solutions, such as plating, are believed by some to be too rigid.5 • Efficient procedure, especially when using a percutaneous approach. Wright delivers another design philosophy The AEQUALIS™ IM Nail was created from extensive proximal humerus dimension and geometry studies.1 Additionally, the basic pathophysiology of displaced unstable 2, 3 and 4-part fractures was revisited,2, 3 resulting in the 5 design principles: 1 Humeral Head Support: The nail must act as a mechanical strut to support humeral head fragments under compressive forces thereby resisting valgus/varus subsidence.
