Home > Proximal Humerus Locking Plate
The proximal humerus locking plate is the threaded-locking member of the ZPLP shoulder range: a low-profile lateral plate whose head screws lock at fixed angles and converge into the humeral head, with inferomedial screws directed toward the calcar region. BoneCraft supplies it as a genuine original implant of the Zimmer Biomet ZPLP periarticular system, through independent distribution.
Varus collapse is the way proximal humerus fixations most often fail: the head fragment tips inward, screws migrate, and the construct loses the reduction millimetre by millimetre. The biomechanical answer is support at the inferomedial corner of the head — the calcar region — where a well-placed screw turns a tipping fragment into a supported one.
The locking plate builds that support into the implant. Its threaded head screws lock to the plate at fixed angles, so the head cluster holds its configuration in osteopenic bone, and the inferomedial screw path gives the surgeon a direct route to the calcar. Longer plates carry the construct into the shaft when the fracture line escapes the metaphysis. Reduction quality, screw placement and plate length remain with the operating surgeon.
The plate is positioned on the lateral cortex below the greater tuberosity line and fixed through the shaft first. Head screws are then driven along their fixed trajectories into the subchondral bone, including the inferomedial screw toward the calcar where the pattern calls for it.
