Femoral Locking Plate Set

Product Overview

The Femoral Locking Plate Set is a comprehensive internal fixation system designed for the surgical management of femoral fractures across proximal, diaphyseal, and distal anatomical regions. Manufactured from high-strength medical-grade titanium alloy, this system features anatomically precontoured plates that conform precisely to the femoral surface, minimizing soft tissue irritation and facilitating fracture reduction. The locking screw technology provides angular stability, creating a fixed-angle construct that is particularly advantageous in osteoporotic bone and comminuted fracture patterns. Available in a wide range of plate configurations—including lateral proximal femoral locking plates, distal femoral locking plates, and supracondylar plates—this versatile system accommodates both left and right anatomies with multiple hole counts. Each plate incorporates combination holes that accept both locking and cortical screws, offering surgical flexibility, while the low-profile head design reduces tissue irritation. Combining anatomical fit, angular stability, and comprehensive sizing, this system delivers reliable clinical outcomes for orthopaedic trauma surgeons managing femoral fractures.

Indications for Use

The Femoral Locking Plate Set is indicated for the following clinical scenarios:

• Proximal femoral fractures including intertrochanteric, subtrochanteric, and basicervical fractures requiring lateral stabilization with locking plate technology.

• Femoral shaft fractures (diaphyseal) including simple, wedge, and comminuted fracture patterns where intramedullary nailing may be insufficient or contraindicated.

• Distal femoral fractures including supracondylar and intercondylar fractures (AO/OTA types 33-A, 33-B, 33-C) requiring anatomical reduction and stable fixation.

• Periarticular fractures involving the femoral condyles where subchondral support and anatomical contouring are critical.

• Osteoporotic fractures where angular-stable locking screws provide enhanced purchase in compromised bone quality, reducing the risk of fixation failure.

• Non-unions and malunions of the femur requiring osteotomy, realignment, and stable internal fixation.

• Pathological fractures secondary to benign or malignant lesions requiring stabilization and structural support.

• Revision surgeries following failed plating or nailing, where combination holes allow for screw placement in previously occupied trajectories.

Key Advantages

The Femoral Locking Plate Set offers a range of distinct clinical benefits that address the specific challenges of femoral fracture fixation.

Anatomically Precontoured Design – Each plate in the system is meticulously shaped to match the specific anatomical contours of the femoral region it is designed for. The lateral proximal femoral plate provides optimal fit for the greater trochanter and femoral neck region, while the distal femoral plate is contoured to respect the supracondylar anatomy. This precontouring reduces the need for intraoperative plate bending, preserves periosteal blood supply, and minimizes soft tissue irritation.

Angular-Stable Locking Technology – The locking screw mechanism creates a fixed-angle construct that functions as an internal fixator, providing superior stability in osteoporotic bone and comminuted fractures. Unlike conventional plating, the locking screws do not rely on friction between the plate and bone, preserving periosteal perfusion and reducing the risk of screw loosening. This technology is particularly valuable in metaphyseal fractures where bone quality is often compromised.

Versatile Combination Holes – Each plate features combination holes that accept both locking and cortical screws, allowing surgeons to choose the optimal screw type for each individual hole based on local bone quality and fracture characteristics. This flexibility provides both fixed-angle stability and the ability to apply interfragmentary compression when needed.

Comprehensive Left and Right Anatomical Options – The system includes both left and right versions for all lateral plates, ensuring an anatomical fit regardless of the side of injury. This side-specific design eliminates the need for plate reversal or extensive bending, reducing surgical time and improving implant congruity.

Low-Profile Head Design – The femoral plates feature a countersinkable head design that reduces soft tissue irritation and minimizes patient discomfort. This is particularly important in the proximal femur where the plate lies close to the gluteal muscles and fascia.

Durable Titanium Alloy Construction – Manufactured from medical-grade titanium alloy, the plates offer excellent corrosion resistance, biocompatibility, and MRI compatibility. The material's modulus of elasticity is closer to cortical bone than stainless steel, reducing stress shielding and promoting physiological load transmission during fracture healing.

Multiple Hole Count Options – With hole counts ranging from 3 to 13 holes depending on the plate type, the system accommodates varying fracture patterns and patient anatomies, from simple fractures requiring minimal fixation to complex comminuted fractures requiring extensive stabilization.

RFQ – Request for Quotation

Q1: What are the available plate materials, and are these plates compatible with both locking and cortical screws?
A: All plates in this set are manufactured from medical-grade titanium alloy, providing excellent biocompatibility, corrosion resistance, and MRI compatibility. The combination holes on each plate accept both locking and cortical screws, allowing surgeons to choose the optimal screw type for each individual hole based on bone quality and fracture characteristics. This versatility provides both fixed-angle stability and the ability to apply interfragmentary compression when needed. Screws are available in 3.5 mm, 4.0 mm, and 5.0 mm diameters.

Q2: What is the difference between the standard lateral proximal femoral plate and the LISS-type proximal plate?
A: The LISS-type plate (Less Invasive Stabilization System) is specifically engineered for minimally invasive plate osteosynthesis (MIPO), featuring a specially designed head geometry that facilitates submuscular insertion through small incisions. It is ideal for proximal femoral fractures where soft tissue preservation is a priority. The standard lateral proximal plate offers a more traditional design with a slightly different head contour and is suitable for both open and minimally invasive approaches. Both plate types provide angular-stable locking fixation and are available in left and right anatomical versions with multiple hole counts.

Q3: Can the Femoral Locking Plate Set be used for both open and minimally invasive surgical approaches?
A: Absolutely. The plates are designed with a low-profile, round, blunt edge that facilitates both open and minimally invasive insertion techniques. The LISS-type plates are particularly well-suited for percutaneous and submuscular approaches, reducing soft tissue trauma and preserving periosteal blood supply. The temporary K-wire fixation holes are useful for provisional stabilization before definitive screw placement, regardless of the approach chosen. The plates' anatomical contouring also simplifies reduction in open procedures.

Q4: What is the recommended technique for measuring screw length during surgery?
A: We recommend using the depth gauge (code 90000108) provided in the instrument set. The gauge is inserted through the drill sleeve after drilling, and the measurement is taken from the far cortex to the near cortex, with an additional 2 mm added for optimal thread engagement. Locking screws are available in various lengths, and it is crucial to select a screw length that engages both cortices in diaphyseal fractures or provides adequate subchondral support in metaphyseal fractures. For locking screws, ensure that the screw tip does not penetrate the far cortex excessively, as this may cause soft tissue irritation.

Q5: Are sterile-packaged options available for the plates and screws?
A: Currently, the plates and screws in the Femoral Locking Plate Set are supplied non-sterile and must be sterilized before use. We recommend steam sterilization at 134°C for 18 minutes. The plates are individually packaged and clearly labeled with the product code, side, and hole count. Sterile-packaged versions can be manufactured upon request for large-volume orders, with an additional lead time. For urgent sterile requirements, we can supply sterile screws through our manufacturing partners.

Q6: What are the standard packaging configurations, shelf life, and minimum order quantities?
A: All implants are supplied non-sterile and must be sterilized prior to use. The shelf life is indefinite when stored in a cool, dry environment. The standard MOQ is 10 units per plate size, but we are happy to accommodate mixed orders and trial kits for hospital evaluations. Screws can be ordered in boxes of 10 units (mixed lengths are acceptable). Instrument sets are typically supplied as a complete set (non-sterile) with a dedicated sterilization tray.
