Multiplanar (Suprapatellar) Tibial Intramedullary Nail System

Kangli Orthopaedics manufactures the Multiplanar (Suprapatellar) Tibial Intramedullary Nail System from titanium alloy for tibial intramedullary fixation procedures. The system combines a suprapatellar tibial nail configuration with multiplanar locking, full-thread locking screws in two thread forms, and terminal end caps. This component arrangement gives distributors and physicians a defined option for tibial shaft nailing and related orthopedic implant procedures.

Suprapatellar Entry for Tibial Nail Placement

The suprapatellar configuration positions the nail entry at the proximal tibia for a suprapatellar nailing approach. It establishes a defined route into the tibial canal when a suprapatellar tibial nail configuration is selected.

Straight-Nail Variant: Tibial Intramedullary Nail System

The Tibial Intramedullary Nail System is the straight-nail variant of this system, supplied in titanium alloy as a long-nail assembly for tibial shaft intramedullary fixation. It features a straight nail body, locking positions at separated ends, and two cannulated end-cap options. This configuration provides a defined longitudinal fixation path and allows the terminal finish to be selected according to the planned assembly.

Straight Tibial Nail Design

The long, straight nail follows the longitudinal axis of the tibia and maintains a continuous implant profile through the central shaft region. Its direct geometry is intended for tibial canal fixation without a shaped lateral offset in the nail body.

Multi-Point Locking Configuration

Transverse locking positions are located near the separated ends of the nail. This arrangement supports fixation at more than one point along the implant length and establishes a defined relationship between the nail and the tibial fixation path.

Cannulated End-Cap Options

The Cannulated Tibial Nail Normal End Cap provides a standard terminal closure for the nail. The Cannulated Tibial Nail Locking End Cap closes the nail while engaging the terminal locking interface. The appropriate option can be selected according to whether terminal locking is included in the planned tibial nail assembly.

Tibial Nail Diameter and Length Selection

Multiple nail diameters and lengths are available for selection according to the planned tibial fixation path. These options retain the same system configuration while allowing distributors and orthopedic specialists to specify the required implant dimensions.

Multiplanar Locking Options

The nail accommodates locking in multiple planes, allowing the selected locking direction to be matched to the planned construct. This arrangement distributes locking across several axes rather than limiting it to one transverse direction.

Full-Thread Locking Screws and Cancellous Thread Form

The full-thread locking screw carries threads along its whole working shaft instead of a smooth central section, so thread remains in contact with bone along the full length of the screw path rather than only at its ends.

The holding-type version puts a cancellous bone thread form on that shaft — a coarser, deeper profile shaped for cancellous bone, which is what the holding-type designation refers to. Where the metaphyseal segment of the tibia is being engaged, that thread form is available on the same full-thread screw geometry rather than requiring a separate screw family.

Double-Thread Screw Advance During Insertion

The holding-type screw is a double-thread design: two thread starts run along the shaft, so one turn of the driver advances the screw by two thread pitches instead of one. The screw therefore reaches its seated depth in fewer turns than an equivalent single-start thread, which shortens the insertion step at each locking site without changing the thread engagement once seated.

Tibial Nail End-Cap Components

The Tibial Suprapatellar Nail End Cap closes the opening at the suprapatellar end of the nail. The Locking End Cap (Tibial) engages with the terminal locking interface, providing a selectable end configuration for the planned locking arrangement. End caps are offered in 0 mm, 5 mm, 10 mm and 15 mm lengths.
