Proximal Humeral Plating System

Print
The AOS PHP is indicated for fractures, fracture dislocations, osteotomies, and non-unions of the proximal humerus. The PHP is an anatomically designed, low profile, titanium locking plate and screw system.

It is designed to treat periarticular or intra-articular fractures of the proximal humerus. The anatomic shape and fixed screw take into account the current demands of surgeons for appropriate fixation, fatigue strength, and minimal soft tissue damage. Locking plates provide improved stability, even in patients with poor bone quality, while reducing screw- loosening. Loss of screw purchase in the bone can result in loss of fracture reduction. Locking plates and screws may also help to reduce the risk of avascular necrosis as the locking plate does not need compressive contact with the bone in order to maintain fracture reduction.

The plate is available in five lengths ranging from 3-14 holes. The system features 4 mm diameter Cancellous Locking Screws and 3.5 mm diameter Locking or Non-locking Cortical Screws.

Features & Benefits

  • Low profile plate and screws.
  • Designed to sit more distally to reduce the risk of subacromial impingement.
  • Proximal Screws with anatomic 130° neck-shaft angle.
  • Double-lead, threaded screw design allows screws to maintain directional alignment upon insertion and reduces cross threading.
  • Limited contact plate design reduces plate to bone contact, limiting vascular trauma and insult to bone.
  • Aiming blocks for easier targeting.
  • Divergent Proximal Screw trajectories for optimal articular reconstruction.
  • Offset Proximal Screws for improved A/P radiographic visibility.
  • Locking or Non-Locking Shaft Screws.
  • Angled Proximal Suture Holes to facilitate rotator cuff repair. Sutures can be attached after plate fixation.
  • Angled Shaft Suture Holes to facilitate deltoid attachment (8, 11, 14 hole plates only).
